A Simple Roadmap to Mexican Casserole Success

Step 1: Warm Up the Oven

Fire up your oven to a toasty 350°F (175°C) so it’s ready for the delicious casserole.

Step 2: Brown the Beef

Drizzle olive oil into a skillet and heat it up over medium flame.

Toss in the ground beef and cook until it turns a beautiful golden brown, breaking it up into crumbly pieces.

Step 3: Spice Up the Mixture

Stir in these flavor-packed ingredients:
  • Taco seasoning
  • Black beans
  • Corn
  • Diced tomatoes
  • Salsa
  • Salt
  • Pepper

Let the mixture simmer and get friendly for about 5 minutes.

Step 4: Create Tasty Layers

Grab a 9×13-inch baking dish and give it a quick spray or butter coating. Start building your flavor tower:
  • First layer: Half of the tortilla strips
  • Second layer: Half of the beef mixture
  • Third layer: Half of the shredded cheese

Repeat these layers one more time for maximum deliciousness.

Step 5: Add the Finishing Touches

Dollop sour cream across the top, sprinkle remaining cheese, and scatter black olives if you’re feeling extra fancy.

Step 6: Bake to Perfection

Slide the casserole into the preheated oven and bake for 25-30 minutes.

You’ll know it’s ready when the cheese turns melty and starts to bubble with excitement.

Step 7: Let It Rest

Pull the casserole out and give it a few minutes to calm down before serving.

This helps the layers set and makes cutting easier.
