Pasta Taco Casserole with Doritos is my answer to the dreaded phrase, “Mom! What’s for dinner?!” You know those nights when you’re barely able to make it through the witching hour(s) between after school and bedtime? Yeah, that’s where this hearty recipe comes in super handy. It’s chock full of taco flavors that kids and adults love with pasta and crunchy Doritos on top. This recipe is a twist on my Taco Pasta Salad  which is always a crowd favorite.

What are your tips for surviving that busy after school time? I would love to hear your ideas in the comments below. Let’s get through this craziness together!

This simple supper recipe has all of your favorite taco flavors but mixed with tender pasta and baked in a casserole dish! Ultimate comfort food, right here. And the best part is, you probably have all the ingredients for this dinner in your kitchen right now! Here’s what you need:

  • A pound of ground beef.  You could substitute ground chicken or turkey too!
  • Cooked Rotini pasta. If you don’t have rotini on hand but you have elbow macaroni, by all means use it! Any shape of pasta will do in this easy recipe.
  • Onions and green bell pepper. These veggies will give lots of flavor and color in the casserole. You can use red, yellow or orange bell peppers too!
  • A packet of taco seasoning. Use a store bought packet for ease, or you can make your own! Try my Homemade Taco Seasoning recipe. It’s simple to make and tastes so good!
  • One cup of salsa. Any brand or level of spiciness will work for this recipe. I always have to keep it on the mild side for my kiddos.
  • Some diced tomatoes. You can use regular tomatoes or find flavored diced tomatoes in a can.
  • Cheddar cheese. I use at least a couple of cups of nice, sharp cheddar in this taco casserole but you could use a mild Monterrey Jack, spicy Pepper Jack, or a combination of your favorite cheeses.
  • Doritos Tortilla Chips. This is my children’s favorite part! Taco casserole with Doritos crushed on top make such a fun and delightful supper. I like to use the nacho cheese flavor, but honestly you could use any flavor you like.

This casserole is perfect as is, or you can top it with sour cream, shredded lettuce, extra salsa, guacamole, chopped green onions or sliced avocado.
