Burrito Casserole

Step 1
Preheat the oven to 350 degrees F (175 degrees C). Coat a casserole dish with cooking spray.

Step 2
Heat olive oil in a large skillet over medium heat. Add onion and cook until translucent, 3 to 5 minutes. Add beef and increase the heat to medium-high. Cook and stir until browned and crumbly, 5 to 7 minutes. Drain and discard grease.

Step 3
Combine refried beans and burrito seasoning in a bowl and mix well. Add mixture to the beef and stir until well combined.

Step 4
Mix condensed soup and sour cream together in a bowl.

Step 5
Place a layer of chips into the prepared casserole dish to just cover the bottom. Follow by 1/2 of the meat mixture, 1/2 of the soup mixture, 1 cup shredded Mexican cheese blend, and 1/2 of the salsa. Repeat layers once more, then top with remaining cheese.

Step 6
Bake in the preheated oven, uncovered, until hot and bubbly, 20 to 30 minutes.
