What Is A Walking Taco?

If you’ve ever been to a kid’s birthday party, graduation party or school sports concession stand in the midwest, you’ve probably tried a walking taco.

All the goodness of Mexican tacos like seasoned ground beef, beans, cheese, are piled into a personal-sized bag of crushed tortilla chips and topped with veggies, sour cream and salsa. They are a delicious and portable meal that both kids and adults love!

While the idea of being portable is convenient, walking tacos in casserole form is a great option for a weeknight meal at home. It contains all the components of tacos that you love, all in one pan!

Quick Look at this Walking Taco Casserole Recipe

  • Ready In: 30 minutes
  • Serves: 8
  • Flavor: Classic taco flavors, melty cheese, and crunchy tortilla chips
  • Equipment: Skillet and a 9×13 baking dish
  • Great For: Taco Tuesday, busy weeknights, potlucks, and game day

What you’ll need for this recipe:

  • Ground beef – Any kind will do. You will drain any excess grease after cooking.
  • Black beans – A second form of protein in this casserole. I love having beans with my Mexican food, so I like the combo of both meat and beans in here.
  • Salsa – Homemade or store-bought is fine. You choose the level of spice.
  • Taco seasoning – I’ve made my own, but most time the packet at the grocery store is just too easy to pass up.
  • Doritos – Or any brand equivalent of nacho cheese tortilla chips. I prefer using these instead of corn chips, or Fritos, as they have more flavor.
  • Toppings – Any veggies or other toppings you’d put on a taco can be used. Find a list of suggested toppings further down in this post.

How to Make Walking Taco Casserole

Make the meat filling – Brown the ground beef and onion until the beef is no longer pink. Drain any excess grease, then stir in the taco seasoning, black beans, green chiles, and salsa. Cook for 2–3 minutes until heated through.

Layer – Spread half of the crushed Doritos into a greased 9×13 baking dish. Top with half of the meat mixture and half of the shredded cheese. Repeat the layers.

The easiest way to crush the chips is to open the bag and use your hands to crush all the chips inside. Good way to get some aggression out!

Bake – At 350 degrees for 20 minutes until cheese is melted and bubbly. Let the casserole rest for about 5 minutes before serving so it holds together a little better when scooped.

What to Serve with Walking Taco Casserole

I like to top the casserole with veggie toppings and leave any sauces for people to add themselves. How perfect would this recipe be for Cinco de Mayo party?

Let everyone customize their own serving with their favorite taco toppings. Some of our favorites include shredded lettuce, diced tomatoes, avocado, black olives, jalapeños, cilantro, pico de gallo, sour cream, salsa, or queso.

This casserole is hearty enough to serve on its own, but it also pairs well with Mexican rice, chips and queso, or fresh fruit like these Watermelon Sticks.

Recipe Variations

The best thing about this taco bake is how customizable it is. Here are some ideas to cater to many different dietary and taste preferences:

  • Double the ground beef for an all-meat recipe or sub in ground turkey or chicken!
  • To make a vegetarian dish, use 2 cans of either pinto, black beans or canned corn.
  • Make your own taco seasoning to adjust the spice and sodium levels to your needs.
  • Use a spicier salsa or a specialty one like salsa verde.
  • Cheddar, Monterrey Jack, pepper jack or a “Mexican” blend cheese are other cheese options.
  • Although there may be cross-contamination during manufacturing, brand name Doritos do not contain gluten. Use certified gluten-free tortilla chips if gluten is an issue.

The possibilities are endless!

How to Store Leftovers

If you are serving fewer people and assume you’ll have leftovers, leave a section of the casserole free of any toppings and store them separate for another time . Leftover taco bake can be kept in an airtight container in the refrigerator for 3-4 days.

The casserole can easily be reheated in the microwave and then topped with your desired toppings. The chips will be slightly soggier when reheated, but overall, the leftovers are just as good!

I would not recommend freezing the casserole, but you could make and freeze the meat & bean mixture and thaw before assembling.

FAQ

Yes! Assemble everything except the chips and add them just before baking for the best texture.

Yes. Fritos create a more traditional walking taco flavor, while Doritos make the casserole cheesier.

Absolutely. Simply replace the beans with another half pound of ground beef.
