HOW TO MAKE BEEF ENCHILADA CASSEROLE?
Start by browning the ground beef in a large skillet over medium heat. When the beef is about halfway browned, add the onion and cook until the beef is fully browned and the onions are soft. Now reduce the heat and add the garlic, cooking for about 1 minute and stirring constantly. Then add 1 cup of the enchilada sauce, beans, and green chiles. Stir to combine cooking over low heat for a few minutes. Now spread a couple of tablespoons of enchilada sauce on the bottom of the casserole dish. Layer 1/4 of the tortillas on the bottom, then spread 1/3 of the beef mixture and 1/4 of each cheese. Then repeat these layers two more times. Finally, top with the last layer of flour tortillas, the remaining enchilada sauce, and the remaining cheese.

Cover the baking dish with foil and bake for 35 minutes or until the cheese is melted and the casserole is heated. Sprinkle with diced avocado, diced tomatoes, minced jalapeno, and chopped cilantro. Let sit for 5-10 minutes before slicing so that the casserole is easier to cut.
