Chef's Tips

Use lean ground beef (90/10) to reduce grease and calories

Let the casserole rest for 5-10 minutes after baking for easier slicing

Make your own taco seasoning to control sodium levels

Toast the tortilla chips lightly before adding for extra crunch

🔧 Troubleshooting Tips

If too watery, drain vegetables well and simmer beef mixture longer to reduce liquid
If too dry, add extra salsa or a can of enchilada sauce
If chips are burning, cover with foil for the last 10 minutes of baking
If beef mixture is too bland, add extra taco seasoning or cumin

Vegetarian: Replace beef with extra beans, quinoa, or plant-based crumbles
Spicy kick: Add diced jalapeños, chipotle peppers, or hot sauce

Breakfast version: Add scrambled eggs and serve for brunch

FAQ

Can I use ground turkey instead of beef?

Absolutely! Ground turkey or chicken works great as a leaner alternative. You may want to add a tablespoon of oil when cooking since they're leaner than beef.

Can I make this casserole ahead of time?

Yes! Assemble everything except the tortilla chip topping, cover and refrigerate up to 24 hours. Add chips and cheese just before baking, adding 10 minutes to the baking time.

How can I make this spicier?

Add diced jalapeños, use hot salsa instead of mild, add cayenne pepper or hot sauce to the beef mixture, or use pepper jack cheese instead of regular Mexican blend.

Can I freeze this casserole?

Yes! Freeze before adding the chip topping for best results. Wrap tightly and freeze up to 3 months. Thaw overnight, add fresh chips and cheese, then bake.

What can I substitute for taco seasoning?

Make your own with: 1 tbsp chili powder, 1 tsp cumin, 1 tsp paprika, ½ tsp garlic powder, ½ tsp onion powder, ¼ tsp oregano, and salt to taste.

Why are my tortilla chips soggy?

Add the chip topping right before baking, not during assembly. Also make sure to drain all canned ingredients well to reduce moisture in the casserole.

Can I make this in a slow cooker?

Yes! Brown the beef first, then add all ingredients except chips to slow cooker. Cook on low 4-6 hours. Top with chips and cheese in last 30 minutes or broil briefly after.

Is this kid-friendly?

Very! Use mild salsa and omit jalapeños for picky eaters. Kids love the cheesy, crunchy layers. You can also let them top their own portions with sour cream and guacamole.

This is my new go-to for Taco Tuesday! So much easier than making individual tacos and my kids actually ate their vegetables. The crunchy chip topping is genius!

I'm vegetarian so I used plant-based crumbles and extra beans - absolutely delicious! My meat-eating husband didn't even notice the difference.

Really tasty! Only wish is that I'd added more seasoning - next time I'll double the taco seasoning. That crispy cheese layer on top though? *Chef's kiss*

This saved my weeknight dinner routine! I prep the beef mixture on Sunday and just assemble and bake during the week. My toddler calls it 'nacho dinner' and begs for it!

As a Mexican-American, I was skeptical but this hits the spot! I use homemade salsa and add some cumin. Reminds me of my abuela's enchilada casserole but easier!

Solid comfort food! I used ground turkey to lighten it up and added extra corn and black beans. Would've given 5 stars but mine came out a bit watery - make sure to drain everything!

This is SO much better than takeout! I love that I can make it ahead and just pop it in the oven after work. The leftovers make amazing burrito filling!

My wife is gluten-free and this recipe worked perfectly with GF chips! We top it with fresh pico and avocado. Better than any restaurant version!

Really good! I wish I'd made more because my teenage boys demolished it. Pro tip: I broiled it for 2 minutes at the end for extra crispy cheese.

This casserole is dangerous - I could eat the whole pan myself! That combo of creamy, cheesy, and crunchy is addictive. Already made it twice this month!
