Ingredients You’ll Need for the Best Mexican Casserole

Let’s begin with the core ingredients that form the foundation of this satisfying casserole. Everything you need can be found in your local grocery store—and you may already have most of it on hand.

Main Ingredients:

• 1 pound ground beef – We recommend lean ground beef (85/15 or 90/10) for best flavor without excess fat.
• 1/2 cup chopped onion – Yellow or white onions both work perfectly.
• 1 can (15 oz) black beans, drained and rinsed – These add fiber, texture, and plant-based protein.
• 1 can (14.5 oz) diced tomatoes, undrained – Adds a sweet, tangy acidity.
• 1 can (10 oz) enchilada sauce – Use mild, medium, or spicy based on your preference.
• 1 can (4 oz) diced green chilies – Mild heat and authentic Tex-Mex flavor.
• 1 can (15 oz) corn, drained – Sweet and juicy, corn balances the savory spices.
• 1 package (1 oz) taco seasoning mix – Or use homemade seasoning for complete control over salt and spice levels.
• 6 flour tortillas, cut into strips – These absorb the sauce and create soft, warm layers.
• 2 cups shredded cheddar cheese – Sharp cheddar is ideal, but you can mix in Monterey Jack or Mexican blend.
• 1 cup sour cream (optional) – Creamy topping to mellow the spices.
• 1/4 cup chopped fresh cilantro (optional) – Adds freshness and color as a garnish.

Step-by-Step Guide to Making Savory Mexican Casserole

Step 1: Preheat the Oven and Prepare the Dish

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with cooking spray or a light coating of oil to prevent sticking.

Step 2: Cook the Ground Beef and Onions

In a large skillet over medium heat, add the ground beef and chopped onion. Cook until the beef is browned and the onions are soft—about 7–10 minutes. Drain any excess fat to keep the casserole from becoming greasy.

Step 3: Add Vegetables and Seasoning

Stir in the black beans, diced tomatoes (with their juices), enchilada sauce, green chilies, corn, and taco seasoning. Mix well to combine all ingredients. Simmer for about 5 minutes, allowing the flavors to meld.

Step 4: Layer the Ingredients in the Baking Dish

Start by laying half of the tortilla strips across the bottom of the greased dish. Next, spread half of the beef mixture over the tortillas, then sprinkle 1 cup of shredded cheddar cheese on top. Repeat with remaining tortillas, meat mixture, and cheese.

Step 5: Bake the Casserole

Bake the casserole in the preheated oven for 20–25 minutes, or until the cheese is melted and bubbly. If you prefer a golden-brown crust on top, broil for the last 2–3 minutes—but watch carefully to avoid burning.

Step 6: Cool and Serve

Let the casserole cool for 5–10 minutes before slicing. This helps it set and makes serving easier. Top with a spoonful of sour cream and a sprinkle of fresh cilantro if desired.

How to Make This Mexican Casserole Your Own

Spice It Up or Tone It Down

If you enjoy heat, consider adding chili flakes, jalapeños, or using a spicy enchilada sauce. For a milder version, skip the green chilies and choose mild taco seasoning.

Swap the Protein

This recipe works beautifully with:

• Ground turkey or chicken – A leaner option with great flavor.
• Shredded rotisserie chicken – Saves time and adds tenderness.
• Lentils or extra beans – Make it vegetarian and protein-rich.

Go Low-Carb or Gluten-Free

Replace flour tortillas with low-carb tortillas, corn tortillas, or even zucchini slices for a lower-carb, gluten-free option.

Dairy-Free Version

Use plant-based cheese and coconut yogurt in place of cheddar and sour cream. You’ll still get that creamy texture with no dairy involved.
