Prepare a 9x13 inch baking dish by spraying it with oil or a non-stick cooking spray. Preheat the oven to 350ºF.

In a large skillet, add the ground beef and onions. Cook over medium heat stirring often until meat is brown and onions have softened.

Once meat and onions are fully browned, drain off excess fat. Add in water and taco seasoning, stir and simmer for 3-4 minutes.

Add the enchilada sauce and beans to the skillet and stir to fully combine.

Sprinkle about 4 cups of Fritos onto the bottom of your baking dish, then top the Fritos with 1 cup of cheddar cheese. Spread the meat mixture on top of that for the next layer then top with remaining cheese.

Bake at 350ºF for about 20 minutes until the cheese is melted and bubbly. You’re your casserole is out of the oven, top with the remaining Fritos.

Allow to cool slightly, then serve with optional topping such as lettuce, tomato, green onions, sour cream, or guacamole.

Enjoy!
