Comfort food doesn’t get much better than this beef burrito casserole. Seasoned ground beef, veggies, rice, and beans are baked together and then topped with melty cheese for a delicious healthy casserole recipe. High protein, gluten-free, and great for meal prep.
Preheat oven to 375 degrees and grease a 9×13 inch baking dish.
Make your beef mixture. Heat up a large skillet over medium heat. Add olive oil and let it get hot (about 30 seconds). Add your onions and salt and pepper and saute for 3-4 minutes until softened. Next, add your beef and break it up with the back of a spoon or meat chopper. Saute for 4-5 minutes. Stir in taco seasoning and saute until meat is browned. Add ground beef mixture to the casserole dish, leaving behind most of the excess grease.
Assemble casserole. Add diced peppers, beans, salsa, rice, and salt and pepper to your casserole dish and mix well to combine, making sure everything is evenly distributed. Pour in broth and stir again until well combined, pushing down the ingredients so they are evenly incorporated. The ingredients should be mostly covered by the liquid.
Bake. Cover with aluminum foil and bake for 40-45 minutes until veggies are softened. Remove the foil and cook for another 10 minutes uncovered until the liquid is fully absorbed. Remove from the oven and sprinkle with shredded cheese. Bake for another 5 minutes until the cheese is melted. Let cool for 5-10 minutes and slice into 8 equal-size pieces.
