Recipe Instructions
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This will ensure the casserole cooks evenly, with the perfect golden-brown crust.
Step 2: Prepare the Tortilla Base
Take a 9×13-inch baking dish and grease it lightly with cooking spray or butter. Lay the flour tortillas in the pan, ensuring they overlap slightly and cover the bottom completely. Gently fold the edges of the tortillas to fit the pan, creating a tortilla “crust” that will hold all of the savory ingredients inside.
Step 3: Cook the Ground Beef and Onion
In a skillet over medium heat, cook the ground beef and chopped onion together, stirring frequently to break the beef into small pieces. Continue cooking until the beef is browned and the onion is tender, about 7-8 minutes. Once cooked, drain any excess fat from the skillet.
Step 4: Add Taco Seasoning and Tomato Sauce
Stir in the taco seasoning mix (or homemade taco seasoning) and tomato sauce into the beef and onion mixture. Mix well to combine, and let it simmer for 2-3 minutes to allow the flavors to meld together.
Step 5: Assemble the Casserole
Spoon the beef mixture over the tortilla base in the prepared pan. Spread it out evenly, then sprinkle with shredded cheddar cheese. This will create a nice cheesy layer that will melt beautifully during baking.
Step 6: Prepare the Egg Mixture
In a blender or using a hand whisk, beat together the eggs, milk, and Bisquick until smooth and well combined. This mixture will form the “impossible” crust of the casserole as it bakes, providing a firm, yet tender texture on top.
Step 7: Pour and Bake
Pour the egg mixture evenly over the beef and cheese layers in the pan. Make sure it covers everything. Place the pan in the oven and bake for 35-40 minutes, or until the casserole is set, golden brown on top, and a knife inserted into the center comes out clean.
Step 8: Let the Casserole Rest
Once the casserole is done baking, remove it from the oven and allow it to cool for about 10 minutes before serving. This cooling period helps the casserole set and makes it easier to cut into neat slices.
Step 9: Serve and Enjoy
Serve your Impossible Tortilla Casserole with optional toppings such as chopped tomatoes, shredded lettuce, and sour cream. These add freshness and balance out the rich, cheesy casserole.
