Taco Casserole with Doritos

This taco Dorito casserole is the easiest way to feed a crowd! Plus, with little kids, there's no need to worry about the taco shells breaking, the contents falling out of the tortilla, or messy toppings all over the floor (moms out there, I know that you can relate)! Instead, you'll just assemble all of your favorite taco ingredients -- plus a few added veggies -- in one casserole dish. It's an awesome prep-ahead option for busy weeknights, it's a meal that your entire family will love, and it eliminates the stress of last-minute dinners.

In this dish, Doritos take the place of traditional taco shells or soft flour tortillas, while also adding so much zesty flavor and crunchy texture to the dish. Plus, the first layer of chips forms a great little crust at the bottom of the taco bake. So, so good!

Dorito Casserole Ingredients

This is just a quick overview of the ingredients that you'll need for our favorite Dorito taco bake. As always, specific measurements and complete step-by-step cooking instructions are included in the printable recipe box at the bottom of the post.

• Ground beef: or substitute with ground turkey.
• Taco seasoning mix: if you would rather use homemade taco seasoning, that's fine -- just omit the water called for in the ingredient list.
• Water: as instructed on the taco seasoning packet, you need water to thin the sauce (since the taco seasoning packets including thickening agents).
• Sweet red bell pepper: a great way to sneak some extra veggies into your family! You can omit the bell pepper if you like, or use a different color sweet bell pepper, such as green bell pepper. Diced onion is also a nice substitute.
• Salsa: use a spicy salsa for added heat, or keep it mild with your kids' favorite.
• Corn: swap out the can of corn for about 1 cup of frozen corn kernels if you prefer.
• Doritos: any flavor will work! I use Nacho Cheese Doritos here, but Cool Ranch and Spicy Sweet Chili Doritos are also great options.
• Shredded cheese: I keep it simple with a package of pre-shredded Mexican style cheese (a blend of Monterey Jack, cheddar, asadero, and queso quesadilla cheeses), but you can use grated cheddar cheese if you like.

How to Make Dorito Casserole

This easy casserole comes together quickly and can be assembled in advance for convenient family dinners!

1. Cook the ground beef and bell pepper in a skillet until the meat is no longer pink. Drain off the fat.
2. Add the taco seasoning and the water to the skillet with the ground beef mixture; simmer for 3-4 minutes so that the sauce thickens.
3. Stir in salsa and corn.
4. Arrange half of the coarsely crushed Doritos in the bottom of a large baking dish. Sprinkle with half of the cheese.
5. Spread the meat mixture over the chips and cheese.
6. Bake, uncovered, in a 350°F oven until the filling is hot and bubbly, about 20 minutes.
7. Sprinkle the remaining cheese and chips on top.
8. Return to the oven for about 5 more minutes, or until the cheese melts.

What to Serve with Mexican Casserole with Doritos

This cheesy casserole goes well with any of these sides:

• Refried Beans or Ranch-Style Beans
• Black Bean and Corn Salad or Summer Corn Salad
• Skillet Cornbread, Honey Cornbread, Corn Sticks, Mexican Cornbread, or Corn Muffins
• Tortilla Chips with Salsa, Guacamole, or Queso
• Easy Pico de Gallo
• Rice
• Green Salad with Red Wine Vinaigrette, Mixed Greens with Dijon Vinaigrette, Wedge Salad, Caesar Salad, or House Salad with Candied Pecans
• Broccoli and Cheese

Storage

• To prep ahead, prepare the beef mixture in advance and store it in an airtight container in the fridge for 1-2 days before assembling the casserole.
• Leftovers will keep in an airtight container in the fridge for 3-4 days or in the freezer for up to 3 months, although the chips on top may become soggy as they sit.
• Reheat individual servings in the microwave for 30-60 seconds (loosely covered). To reheat an entire casserole, allow the dish to sit on the counter for at least 30-60 minutes so that it comes to room temperature. Tent loosely with foil (to prevent the top from getting too dark), and warm in a 350°F oven until heated through, about 15-20 minutes.

Recipe Variations

• Swap out the ground beef and use ground turkey or ground chicken instead.
• Try adding other veggies to the filling. You might like to sauté some diced onion with the ground beef, or mix in some steamed baby broccoli florets or a can of diced green chiles. Minced garlic would also be a great flavor booster.
• Black beans, kidney beans, or pinto beans would also make a great addition to the taco bake.
• Add a can of drained Rotel diced tomatoes with green chilies if you'd like some zesty kick! Be warned, the Rotel tomatoes can definitely get spicy!
• Instead of a packet of taco seasoning mix, feel free to use your favorite homemade taco seasoning in this recipe. If using homemade taco seasoning, omit the water called for in the ingredients. The store-bought packets of seasoning mix require water to thin the sauce (since the mix has thickening agents in it).

Tips for the Best Dorito Casserole Recipe

• Keep a close eye on the casserole during the final few minutes, since the chips on top can burn easily.
• Set up a "taco bar" and let your family members garnish their individual servings with their favorite taco toppings, such as fresh cilantro, sliced green onions, minced red onion, sliced black olives, sour cream, diced avocado, guacamole, extra salsa.
• Cooking for a Smaller Family? Cut the ingredients in half and bake the casserole in an 8-inch square pan.
