Easy Taco Casserole with Tortillas and Chips

My favorite easy taco casserole recipe gives you all the flavor of a taco night, cut into neat squares like lasagna. A crisp flour tortilla crust holds everything together, a layer of chips soaks up the cheesy taco beef, and more chips on top stay crunchy.

Tips and Notes Before You Start

• The tortilla crust is the secret. It keeps it all from sliding apart.
• The chips inside soften on purpose. They soak up the sauce like tortillas in an enchilada casserole. The ones on top stay crunchy.
• A full jar of salsa keeps it saucy. The filling stays moist, and the crisp tortilla bottom still holds up.
• Taste before you salt. Chips, salsa, and taco seasoning are all salty, and mine needed no extra salt at all.
• It feeds a crowd. One pound of beef makes 6 to 8 generous squares.

What You’ll Need for Taco Casserole

Flour tortillas. Use the big burrito-size ones, 10 inches across. It took 5 of mine to cover the bottom of a 9×13, with one torn into pieces to patch the corners.

Crushed chips. Use plain tortilla chips or go for more flavor and use your favorite Doritos (I used the classic nacho cheese ones here). You’ll need about half a bag, crushed. Cool Ranch or Fritos work too, as do slightly stale chips!

Ground beef. I like 85/15, which has enough fat to taste beefy without making the casserole greasy. Spoon off most of the fat after browning.

Salsa. Make your own or use a jar. I think a smooth, restaurant-style salsa works especially well, because it gives you plenty of sauce without big chunks of tomato. If yours is chunky, a few seconds in the blender will smooth it out.

Black beans and corn. Drain and rinse the beans so the filling doesn’t get muddy. I used frozen corn straight from the bag, with no need to thaw it. Canned corn works too, drained.

Taco seasoning. Two tablespoons of my homemade taco seasoning or one store-bought packet. Both work fine. Either way, skip any extra salt until you’ve tasted the filling, since the Doritos and salsa are salty too.

Cheddar. Shredded cheddar or a Mexican blend. It goes in three places: stirred into the filling, sprinkled over the tortillas, and melted on top.

Onion and garlic. Diced and minced.

How to Make Taco Casserole

Heat your oven to 350°F with a rack in the middle, and butter or spray a 9×13 baking dish. We’re really making this in two parts: a crisp tortilla and chips base in the dish, and a cheesy taco filling in the skillet.

Step 1: Line the dish with tortillas

Lay the tortillas in the dish, overlapping them and letting them come about an inch up the sides. Then tear one into pieces to fill the corners and any gaps. Round tortillas in a rectangle dish always leave little triangles at the corners, so don’t worry if it takes some patching. Just make sure no dish shows. My first try left a strip of bare dish down each side, so I tore up one more tortilla to fill them in.

Pop the dish into the oven while you cook the filling, about 5 to 8 minutes. This helps because the tortillas dry out a little, so the bottom bakes up crisp instead of soft.

Step 2: Brown the beef and onion

In a large skillet over medium-high heat, brown the beef and onion together, breaking up the meat as it cooks, for about 8 minutes. Add the garlic for the last minute, then spoon off most of the fat. Stir in the taco seasoning and cook it for a minute, which wakes up the spices.

Step 3: Add the beans, corn, and salsa

Add the beans, corn, and salsa and stir everything together. Let it simmer for 2 to 3 minutes, stirring, until it’s thick enough to mound on a spoon but still a little saucy. Here’s how to tell: drag a spoon through the filling. If it leaves a path that doesn’t fill right back in with liquid, you’re there. Be careful not to cook it much past that point, since the Doritos drink up sauce in the oven and it keeps thickening as it bakes.

Step 4: Stir in some of the cheese

Take the skillet off the heat and stir in the filling cheese until it melts. This is the trick that makes the filling creamy and holds it together, so the squares don’t fall apart when you serve them.

Step 5: Build the base

Take the dish out of the oven. Sprinkle the chip-layer cheese over the tortillas, then the chip layer in an even layer. The cheese melts and glues the chips to the tortillas, which helps everything come out together as one square.

Step 6: Add the filling and the rest of the cheese

Spoon the beef mixture over the chips and spread it gently to the edges. Spooning it on in dollops, then spreading, keeps you from pushing the chips around underneath. Top it with the remaining cheese.

Step 7: Bake, then add the crunchy top

Bake it uncovered for 20 minutes, until the cheese is melted and the edges are bubbling. Then scatter the crunchy-top chips over the cheese and slide it back in for 5 more minutes. The chips toast just enough in that time. If they went on at the beginning, they’d be soft and too dark by the time the casserole was hot.

Step 8: Let it rest, then cut

Let the casserole sit for 10 minutes before you cut it, so the cheese sets and your squares hold their shape. I cut mine into 6 big squares, 2 across and 3 down, but 8 smaller ones are plenty for most people. Use a sharp knife and press straight down through the tortilla crust rather than sawing. The crisp edges take a little extra push, just like cutting through a hard taco shell. Then slide a thin spatula underneath and lift.

You’ll notice the chips under the beef soften into the filling, a lot like tortillas in an enchilada casserole. That’s normal, and it’s why the extra chips go on top at the end.

Step 9: Add the toppings

Add the toppings right before serving, because lettuce wilts quickly on a hot casserole. We like shredded lettuce, diced tomato, sour cream, green onion, sliced black olives, and a little cilantro. Jalapeños are there if you like some heat. You can top the whole dish, or set everything out in little bowls and let everyone build their own square.

Can I Make Taco Casserole Ahead?

Yes. Build it all the way through the top layer of cheese, but hold back the crunchy-top chips. Let it cool, then cover it and keep it in the fridge for up to 1 day. When you’re ready, bake it covered for 20 minutes, then uncovered for 15 to 20 minutes, until it’s hot in the middle. Add the top Doritos for the last 5 minutes.

How to Store and Reheat Taco Casserole

I like to cut the leftovers into squares and pack them into individual containers, then label each one with the date. That way they’re grab-and-go lunches. Keep them covered in the fridge for up to 3 days. You can learn more about how I store leftovers safely in my guide here.

To reheat, warm a square in a 350°F oven for about 15 minutes, or in the microwave for 1 to 2 minutes. Add fresh toppings after reheating. The chips on top will soften overnight, so a handful of fresh ones brings the crunch back.

Taco Casserole FAQs

Why is my taco casserole soggy or dry?

It almost always comes down to the filling. Too wet, and the chips and tortillas go soft. Simmered too long, and it bakes up dry. Stop when a spoon leaves a trail but the filling still looks a little saucy, and don’t skip drying the tortillas in the oven first.

Can I use corn tortillas?

Yes. Corn tortillas are smaller, so you’ll need about 8 to 10 of them to cover the dish, overlapped and patched the same way.

Is taco casserole spicy?

Not with mild salsa and regular taco seasoning. For more heat, use medium or hot salsa, pepper jack cheese, or pile on the jalapeños.

Can I make it with chicken or ground turkey?

Yes. Ground turkey browns the same way as beef. For chicken, soften the onion in a little oil, stir in the seasoning, then add about 2 cups of cooked, shredded chicken with the beans, corn, and salsa.
