Ingredients (Serves 6–8)

1 lb (450 g) ground beef
1 packet taco seasoning (or 2 tablespoons homemade)
1 small onion, diced
1 can (10 oz) diced tomatoes with green chilies (like Rotel-style)
1 can (15 oz) whole kernel corn, drained
1 can (10.5 oz) cream of chicken soup
1 cup sour cream
2 cups shredded Mexican blend cheese (divided)
3 cups crushed tortilla chips
½ teaspoon garlic powder
½ teaspoon cumin
Salt and black pepper to taste

Optional add-ins:

1 can black beans, drained
1 diced jalapeño
½ cup chopped bell peppers
Fresh cilantro for garnish

Step-by-Step Instructions

1️⃣ Preheat the Oven

Preheat your oven to 180°C (350°F). Lightly grease a 9×13-inch baking dish.

2️⃣ Cook the Beef

In a large skillet over medium heat, cook the ground beef and diced onion until browned and fully cooked.

Drain excess grease.

Stir in:

Taco seasoning
Garlic powder
Cumin
Salt and pepper

Add the diced tomatoes with green chilies and simmer for 3–4 minutes.

3️⃣ Prepare the Creamy Mixture

In a separate bowl, mix together:

Cream of chicken soup
Sour cream
1 cup shredded cheese

Stir until smooth and creamy.

4️⃣ Assemble the Casserole

Layer the ingredients in this order:

Half of the crushed tortilla chips
Half of the beef mixture
Half of the corn (and beans if using)
Half of the creamy mixture

Repeat layers once more.

Top with the remaining 1 cup of shredded cheese.

5️⃣ Bake

Bake uncovered for 25–30 minutes, or until hot and bubbly and the cheese is melted and lightly golden.

Let the casserole rest for 5–10 minutes before serving to help it set.

Tips for the Best Casserole

✔ Slightly crush the tortilla chips but don’t pulverize them — you want some texture.
✔ Use freshly shredded cheese for better melting.
✔ Let it rest before serving to prevent it from being too runny.
✔ Add extra jalapeños if you like more heat.
✔ For extra crispiness, add a few whole chips on top before baking.

Flavor Variations

🌶 Spicy Version

Add chopped jalapeños, hot sauce, or pepper jack cheese.

🫘 Bean Lover’s

🐔 Chicken Swap

Substitute shredded rotisserie chicken for ground beef.

🧀 Extra Cheesy

Add an additional layer of cheese between every layer.

🥑 Fresh Toppings

Top with sliced avocado, pico de gallo, or chopped cilantro after baking.

What to Serve With It

This casserole is hearty on its own, but pairs well with:

Mexican rice
Refried beans
Simple green salad
Guacamole and salsa
Warm flour tortillas

Storage & Reheating

Refrigerator:
Store leftovers in an airtight container for up to 4 days.

Reheat:
Microwave individual portions or bake at 175°C (350°F) for 10–15 minutes until warmed through.

Freezer:
Freeze tightly wrapped for up to 2 months. Thaw overnight in the refrigerator before reheating.

Make It Ahead

You can assemble the casserole up to 24 hours in advance and store it covered in the refrigerator.

When ready to bake, allow it to sit at room temperature for 20–30 minutes before placing in the oven.

Why This Recipe Works

The combination of seasoned beef and tomatoes provides bold flavor, while the creamy soup and sour cream create richness that balances the spice. The tortilla chips absorb just enough moisture to soften slightly while still maintaining a satisfying texture.

The melted cheese ties everything together, creating a warm, comforting dish that’s both nostalgic and flavorful.
