How to Make the Cheesy Tex-Mex Beef Casserole
A perfectly layered casserole delivers balanced bites every time. Follow this simple step-by-step guide.
Step 1: Preheat and Prepare
Preheat your oven to 375°F (190°C).
Grease a 9×13-inch baking dish lightly with oil or cooking spray.
A well-greased dish prevents sticking and creates beautifully defined layers once sliced.
Step 2: Brown the Beef
Heat a large skillet over medium-high heat.
Add the ground beef and cook until browned, about 5–7 minutes.
🔍 Pro Tip:
Drain any excess fat for a cleaner, less oily result.
Step 3: Add Aromatics & Seasoning
Add the diced onion and cook for 3–4 minutes until softened.
Add garlic and cook for 30 seconds until fragrant.
Sprinkle in the taco seasoning and mix well.
This step “blooms” the spices, enhancing aroma and depth by releasing essential oils.
Step 4: Combine Ingredients
Stir in:
- Black beans
- Corn
- Tomatoes with green chilies
Mix until everything is evenly incorporated. This becomes the flavorful base that carries the entire dish.
Step 5: Layer the Casserole
In the baking dish:
- Spread half the meat mixture.
- Sprinkle 1 cup crushed tortilla chips.
- Pour half the enchilada sauce.
- Add 1 cup cheese.
Repeat with:
- Remaining meat
- Sour cream (spread gently)
- Remaining sauce
- Remaining chips
- Final layer of cheese
This creates a beautiful multi-layered effect.
Step 6: Bake
Cover with foil and bake for 20 minutes.
Remove the foil and bake for 10–15 minutes more until cheese is bubbly and golden.
Step 7: Rest & Serve
Let the casserole rest for 5–10 minutes.
This allows the layers to settle and makes slicing easier.
Top with:
- Fresh cilantro
- Sliced avocado
- Lime wedges

Common Mistakes & How to Avoid Them
