All of your taco favorites combined into one healthy and comforting beef taco casserole! Great for a satisfying meal, meal prep, and paleo and Whole30 approved!
This recipe first appeared on Instagram in partnership with Cece’s Noodle Co.
Who else is a fan of casserole 😏😁 to be honest, I don’t think I really knew what a casserole was until I really started getting into cooking and was looking at different recipes every day on the computer.
My mom never really made them (at least not that I can remember, but I do have the worst memory ever). But I now love them! It’s a hearty and cozy meal, all packed into one big baked dish. So today I’m taking one of our favorite meals (tacos!) and sharing a paleo and Whole30 approved beef taco casserole!
How to make Whole30 Beef Taco Casserole
The beauty of casseroles is you literally mix all the ingredients together, place them in a large baking dish, and let the oven bake them together until all the flavors are melded together. It usually has some kind of binding agent to help it hold together so you can cut into it like a pie (probably the wrong analogy, but that is what my brain can think of at the moment ha).
This beef taco casserole does just that, and you only need less than 10 ingredients! Here is what you need:
- ground beef
- yellow onion
- bell peppers
- kale
- cherry tomatoes
- taco seasoning
- sweet potato noodles
- salsa
- mayo
- salt & pepper
We start off my sautéing the ground beef until slightly browned. Then we add in the onion and some taco seasoning and sauté for a couple more minutes. Next add the peppers, kale, the remaining taco seasoning, and some salt and pepper, and cook for a couple more minutes.
Turn off the heat and add the sweet potato noodles and cherry tomatoes and transfer to a greased baking dish. Make the binder by mixing together the mayo and some of the salsa. Distribute over the taco casserole and mix to combine. Then we just bake until firm and crispy on top!
I love topping it with avocado, more salsa, cilantro, and hot sauce, but whatever you like will work! If you find it a little runny (more on that below), you can eat it out of a bowl!
How to meal prep/prep in advance
Beef taco casserole is a great dish to prep ahead of time or meal prep for the week! There are a few different ways you can meal prep it:
- Make the beef and veggie mixture and just store it in the fridge. Then, when you are ready to assemble, just put it in a large glass baking dish, make the salsa and mayo mixture, and bake.
- Bake it on Sunday and store in the fridge for a quick meal during the week. Either reheat it in the oven or microwave depending on your setting.
If you have leftovers, just store it in the fridge in a tightly sealed glass container. It saves well and should be good for up to a week.
Can you freeze Beef Taco Casserole
Yes! Depending on how you want to serve it, you can freeze two different ways:
- Bake it and then freeze the whole casserole. You will need to defrost the whole casserole when you are ready to eat, but makes a great option for a family.
- Bake it and then cut it into serving portions and freeze them individually. Then you just need to defrost each serving when you are ready to eat.
To defrost, just place in your fridge the night before and it should be ready to heat up the next day. To reheat, you can either put it in the microwave for a quick option or bake it in the oven until warmed through.
Can I use a different meat?
Yes, any meat will really work! You can substitute ground chicken or ground turkey and I think even shredded chicken will work just find. You just won’t have to cook shredded chicken beforehand.
Tips to avoid a runny casserole
A few factors play into how this casserole will turn out. The goal for it is to stay together and not be runny. You will have a little excess liquid, but don’t want too much.
To avoid a runny beef taco casserole, try to use a chunky salsa. If it is has too much liquid, it will transfer over when you bake it. If you can only find a more liquid salsa, add more mayo for a binder.
Second, make sure you drain all the liquid from the beef before mixing it with the rest of the ingredients. I use a slotted spoon to transfer it over.

Transfer mixture to the baking dish, leaving behind the grease.
- In a small bowl, mix together 1 cup salsa and mayo. Pour over sweet potato and beef mixture, evenly distributing. Use a fork to make sure it is evenly spread throughout the casserole. Top with more salsa if desired and bake for 35 minutes until firm and crispy on the top. Let rest for 5 minutes to firm up some more. Top with your favorite toppings and enjoy!

1. This looks awesome!
2. I hate HATE to be that person, but I also HATE mayo, is there any other type of binder I could sub in? Maybe arrowroot powder, or almond flour? I’m really sorry I honestly just HATE mayo.
thanks so much for this dope recipe!
Kelly
January 4, 2019 at 6:19 pmHaha!! Thank you! You could maybe try an egg or two mixed with the salsa and some almond or arrowroot flour. The mayo helps it stick together, but the arrowroot might do the same. Let me know if you try it!

April 9, 2019 at 6:37 pmThis is sooooo good! Thanks for the awesome recipe!

Amanda Lussiana
January 5, 2019 at 10:46 amDo you think spiralized butternut squash would work? If not I’ll have to break down and sprialize my own potatoes. Can’t find a prepackaged version. This is purely a lazy question 🤣
Kelly
January 7, 2019 at 10:59 amHaha! Yes, that will totally work and will be a great sub!
Amanda
January 9, 2019 at 11:41 amI put in the effort for the sweet potato, used ground turkey and it was bomb! My husband and kids weren’t so sure about all the veggies, but ALL loved it!
Kelly
January 10, 2019 at 4:59 pmHaha yes!!! So glad to hear that! Happy y’all enjoyed!
Michelle
January 7, 2019 at 8:34 pmI made this tonight using butternut squash noodles and it turned out great!!
Kelly
January 8, 2019 at 9:38 amLove that sub! Glad you enjoyed it Michelle!

It’s become a regular side dish or main meal in my household.
Kelly
September 4, 2020 at 10:30 amSo happy to hear that Jacqueline! Thank you for the review!
Sabrina
January 7, 2019 at 9:02 pmKelly, this recipe was out of this world! If I’m being honest, I was a little skeptical about the mayo but you don’t even notice it. My husband actually made extra salsa/mayo to top his. Absolutely delicious!!!
Kelly
January 8, 2019 at 9:39 amHaha!! I love when that happens lol! I’m glad y’all liked it – thank you for trying it!!
Sasha
January 7, 2019 at 9:28 pmMade this today and it was delicious! 🤗 Your blog post above with tips and tricks were very helpful! Easy read, easy to follow, delicious result! I’m also stoked for the homemade taco seasoning that was in the recipe and can’t wait to use it in other recipes! 😊
Kelly
January 8, 2019 at 9:39 amYay! So glad you liked it Sasha! And I love having that homemade taco seasoning on hand! Thanks for trying it!
Kathleen Pina
January 11, 2019 at 12:03 pmMade this recipe last night, and loved it. Having the leftovers for lunch today and just as yummy. My husband loved it too, and he’s tough to please!
Kelly
January 14, 2019 at 9:33 amAlways good when the husband approves! So glad you liked it Kathleen and thanks for trying it!
Caitlin Mundy
January 15, 2019 at 3:00 amI’ve now made this recipe a few times, once subbing sweet potato cubes for the spiralized noodles (which works, even though the noodles are much better) and topped with black bean chipotle dip, avocado and extra cilantro. It’s amaxing no matter what, and so simple to follow! I needed a quick easy dinner tonight with some lunch leftovers and it was done in 35 mins. My mom who hates all Mexican food even tasted it, and LOVED it. Great work here Kelly! Keep it up
Kelly
January 16, 2019 at 12:11 pmYay!! So glad to hear that and also glad that Stac liked it (I think that is your mom’s name if I’m remembering haha)! Thanks so much girl!
Shaina

You must not be from the Midwest 😂 I literally just found out this year that not everyone in the US refers to a baking dish as a “casserole dish”.
Great looking recipe, super excited to try it!
Kelly
January 31, 2019 at 7:48 pmHaha yes!! I am from the Northeast lol! I’m a fan of them now though! Hope you enjoy Anna 🙂
Kathy
February 27, 2019 at 11:32 amSeems like a great way to use left over taco meat. Similar but different flavors
Kelly
March 11, 2019 at 10:51 amYes! It would be great with any leftover meat!
Abbie (lifeoffelm.eats)
March 4, 2019 at 11:44 amI made this recipe last night. So easy and super tasty! My husband, who is a VERY picky eater, also ate it and LOVED it! Will definitely make again!
Kelly
March 6, 2019 at 11:16 amYay! So glad to hear that! Love when the husbands approve. Thanks for trying it Abbie!
Amanda Acquino
March 10, 2019 at 8:17 pmThis recipe is BOMB. I am not a vegetable person at all and this is the perfect meal for me! I am going into my 2nd week of Whole30 and I’m excited to have some delicious meals.
Kelly
March 11, 2019 at 7:46 amYay! I try to get in as many veggies as I can in meals and this makes me so happy to hear! Thanks so much for trying it Amanda and good luck on your Whole30!
Leah
March 12, 2019 at 12:07 amHi! I really hate to be that picky person who can’t eat such and such but, I can’t do peppers of any color. I love them but, they don’t love me! Lol! Anyway, I am afraid if I leave them out all together the casserole will be too runny. Any ideas for substitutes? Maybe mushrooms? Thanks in advance!
Kelly
March 12, 2019 at 11:15 amHi Leah! No worries! I would definitely add something in their place. Any veggie would work that you like – carrots, broccoli, cauliflower, zucchini, mushrooms….some of those aren’t your typical taco favors, but I still think it would be good. Hope that helps!
Leah
March 12, 2019 at 1:14 pmGreat suggestions! Thank you!
Kelly
March 13, 2019 at 8:05 pmYou are welcome!
Allie
March 13, 2019 at 4:37 pmThis looks amazing! I’m working on my grocery list for meals I’ll be making next week, and am definitely including this one. I’m generally not a picky eater at all, but I can’t stand kale. Do you have any suggestions for substitutes?
Kelly
March 13, 2019 at 8:08 pmHey Allie! You can substitute any green that you like – spinach, turnips, collards… or you could just leave it out and add a little more of the other veggies if you wanted. I just try to get some green in most meals, so I added it in there. Hope the helps!
Krysta
March 18, 2019 at 3:47 amGreat recipe!!!! Do you think this would freeze well??
Kelly
March 20, 2019 at 11:51 amHi Krysta! Yes, it would freeze great! You can either freeze the whole thing and then defrost and bake again, or freeze individual servings and heat up again. Both ways work! Hope that helps.
Jenna
March 20, 2019 at 8:47 pmThis was DELICIOUS!! I loved it so much and so did the hubby. I added fresh squeezed lime, Greek yogurt, and cilantro. Yum!!
Kelly
March 31, 2019 at 12:36 pmYum! Love those toppings! So glad you guys enjoyed it, thanks for trying it Jenna!
Joanie
March 26, 2019 at 9:13 amDo you boil the noodles first, or add them dry?
I’ve seen recipes that do it both ways.
Kelly
March 31, 2019 at 12:39 pmHi Joanie! You add the noodles to the pan and mix them with the other ingredients. They will bake in the oven. Hope that helps!
Megan
August 19, 2019 at 6:35 pmWish that was written into the recipe
Kelly
September 3, 2019 at 12:09 pmHi Megan! I will always say if something is cooked. Since it doesn’t specify, they are raw. I can update the recipe though to make it more clear.
Caitlynn
April 2, 2019 at 7:22 pmThe flavor combo is awesome! Also, you can’t even tell there’s kale in here. Seems like a winner for picky vegetable eaters.
Kelly
April 15, 2019 at 9:34 amSo glad you liked it Caitlynn! And I’m all about trying to sneak in the veggies. Thanks for trying!
Lindsay Himelright
August 5, 2019 at 5:26 pmWhoa! I made this last night to have for dinner tonight, and it was the most delicious #whole30 meal I’ve eaten! It’s extremely flavorful with just the right amount of kick at the end. My husband loved it too!
Thank you @eatthegains for creating this masterpiece! Delish!
Kelly
August 16, 2019 at 4:11 pmSo happy you loved it Lindsay!! And I always love it when the guys can get on board too! Thank you for trying it and I’m glad you enjoyed!
Allyson Morris
August 12, 2019 at 10:28 pmThis recipe is absolutely delicious!! I have made it several times & it is always a family hit! Thank you for sharing your delicious creations ❤️
Kelly
August 16, 2019 at 4:15 pmSo glad to hear it Allyson! Thank you for trying it!!
Marissa B
August 21, 2019 at 6:59 pmThis recipe is so good! It made a huge casserole! I cut individual portions and froze them because this casserole is just too good to waste. It is so easy to prepare, and it has great flavor. It wasn’t runny at all. I will definitely be making this again!
Kelly
September 3, 2019 at 12:13 pmSo happy to hear that Marissa!! Love that you froze some for later too. Thank you for trying it and glad you enjoyed!
Steffi G
August 26, 2019 at 11:28 amThis is awesome! I usually hate meal prep because I can’t eat the same dish more than two days in a row. With this recipe, I tripled the amounts and ate it for lunch and dinner until it was finished. It is so damn good!
Kelly
September 3, 2019 at 12:17 pmAw yeah, that makes me so happy! I agree, I get tired of eating the same thing. I’m so happy you liked it – thanks for trying it Steffi!
Maria
September 16, 2019 at 8:35 amStumbled across this on Pinterest and it has easily become one of my favorite meals!!! I’ve made it for new mamas and friends and it becomes one of their go-to’s as well. My toddler approves too, which is always a win! I recommend prepping the veggies in advanced so it’s less time in the kitchen all at once.
Kelly
September 19, 2019 at 2:30 pmI love hearing that! And just a good tip! So glad it’s been a hit and thank you for trying it Maria!
Karissa Hall
December 13, 2019 at 3:57 pmCould cauliflower rice be used as a substitute to the noodles?
Kelly
December 18, 2019 at 4:14 pmHi Karissa! I think so, but I’m not sure how much you would need. You could also sub a different kind of noodle if needed. Let me know if you try it!
Jenna
January 6, 2020 at 12:27 pmI have made this recipe over and over and over because it it that good!! I even got my mom hooked on the recipe! I slightly altered it to fit with what was in my fridge and my favorite is adding in some zoodles (cooked first and drained well) and using chipotle lime mayo. I always make this during a whole30 and make is frequently when not doing W30!! Thanks for the flavorful meal!
Kelly
January 9, 2020 at 9:54 pmOMG chipotle lime mayo!? That sounds so good! Love that you add veggies and make it your own too! So glad you like it Jenna!
Molly
January 12, 2020 at 10:53 amWhat type of salsa did you use?
Kelly
January 12, 2020 at 3:35 pmHey Molly, I don’t recall off the top of my head, but any kind you like should work. Just make sure it is Whole30 compliant if you are on the Whole30.
Amber Orman Pugh
March 4, 2020 at 11:13 amSo yummy! I can do much cheese/ dairy due to a milk allergy- this recipe doesn’t even need it!
Kelly
March 5, 2020 at 10:48 amYay, so glad you like it Amber! Thanks for trying it!
Jo
March 10, 2020 at 12:57 amThis recipe is very simple but so tasty. My family couldn’t stop commenting about how delicious it was. I made my own sweet potato noodles as pre-packaged noodles aren’t something I can get in my town but they’re simple enough to make with a vegetable spiralizer. I also used a homemade Whole30 compliant tomato sauce instead of salsa as I had some in the fridge to use up. But other than that, I stuck to the recipe. It’s a recipe that is going into our family recipe folder so we can make it again.
Kelly
March 23, 2020 at 11:24 amAw yay, I love hearing the whole family loved it! Love that you made it work for you too. Glad you guys enjoyed it and thank you for trying it!
Julie Kemp
April 18, 2020 at 9:54 amOBSESSED. So easy and my husband loved it. Our grocery was out of SP noodles so we subbed in carrot noodles, which worked great. We will prob add this to our weekly rotation of recipes 😅 was also amazing as leftovers!!
Kelly
April 19, 2020 at 6:02 pmLove the carrot noodle sub! So glad you everyone liked it Julie and thanks for trying!!
Allie
April 20, 2020 at 2:41 pmThis sounded amazing, but I was surprised to learn it was even better than it sounded, Ive already recommended to all my friends. We had ours with tostitos for a little added crunch. As an added bonus, my genius husband added a fried egg and salsa one morning and it was all of a sudden a delicious breakfast taco bowl. We WILL be making this again!
Kelly
April 27, 2020 at 10:10 amHaha yay! Love the addition of Tostitos to it and a fried egg!! So glad you guys liked it and thanks for trying!
Melissa Acker
May 18, 2020 at 4:20 pmNot entirely sure how this recipe doesn’t have a full five stars from everyone. My hobby is making meals from food bloggers who dedicate their lives to creating awesome recipes and this one hands down takes the cake for best recipe I have ever made! It’s creative, it’s insanely easy to make, so nourishing and the best part, my boyfriend loves it just as much as I do! This is a staple in our household and we can’t thank you enough for sharing your genius with us! I can tell you right now we wouldn’t be so well fed without you!
Kelly
May 27, 2020 at 10:56 amWell this is the best comment ever! Thank you so much Melissa and I’m so glad you enjoyed it! THANK YOU for trying it!
Stephanie
May 24, 2020 at 2:13 pmThis recipe was SO good, and even hubby approved 🙂 I was a little worried that the mayo would taste a little funky but it wasn’t even noticeable. Just the perfect amount of creaminess!
Kelly
May 27, 2020 at 1:22 pmSo glad you both enjoyed! Thanks for trying it Stephanie!
Amanda
May 25, 2020 at 2:29 pmI love this recipe but just found out I am allergic to egg. Do you have a substitute for mayo?
Kelly
May 27, 2020 at 1:24 pmI would look for an egg free mayo – I know they make that! If not, you can maybe try coconut cream instead. I haven’t tried it so not sure how it would work, but it might!
Gillian Klein
August 6, 2020 at 8:57 pmLove this recipe! I’ve made it multiple times and I love having the taco seasoning on hand already, it makes it super quick!
Kelly
August 17, 2020 at 10:01 amSo glad to hear that Gillian! Glad you like it and I love having the homemade seasoning on hand too!
Grace
August 10, 2020 at 8:54 pmI’ve made this recipe several times and it’s always delicious!! I’m lazy and can’t find pre-made spiraled sweet potatoes so I shred them in the food processor and it still turns out amazing! Thanks for sharing this recipe!
Kelly
August 17, 2020 at 9:55 amI love that idea of shredding in the food processor! So glad you like it Grace and thanks for trying!!
Emilee
January 6, 2021 at 3:53 pmMy whole family LOVES this meal! So easy to make & so, so good!!
