Instructions
Preheat oven to 350 degrees.
In a large pot or Dutch oven, brown the beef and onions. Add the garlic and cook for another minute. Drain. Add 2 tablespoons of the taco seasoning and 1/3 cup water and cook until liquid has reduced. Remove from pan and set aside.
In the same pot, melt butter over medium heat. Stir in remaining 2 tablespoons of taco seasoning, salt, and pepper. Add the flour and cook for a couple of minutes until thick. Slowly whisk in the beef broth and milk until combined and cook for 3-5 minutes or until mixture is thick. Stir in the reserved meat mixture, corn, and beans.
Pour into an 11X17 inch baking dish. Top with crushed tortillas. Bake for 10 minutes. Sprinkle the cheese on top and bake for 2-4 minutes or until cheese is melted.
