Walking Taco Casserole Recipe (Delicious Taco Night Dinner Recipe)

Walking tacos are traditionally made inside individual bags of chips (such as Doritos or Fritos) where you layer the taco toppings inside the bag, on top of the chips! They’re made to be eaten while “walking” or on the go. This casserole version takes all those ingredients and flavors of a classic walking taco, but instead, layers everything into a casserole dish. Perfect family style dinner that is cozy, easy, shareable, and everyone loves.

The crunchy chips act as the taco shells, the saucy taco seasoned ground beef and beans make this a hearty taco dinner, and of course the fresh toppings make it complete – just like a classic taco!

Serve this for an easy weeknight meal that the entire family is sure to love, to celebrate Cinco de Mayo, serve it at a family gathering, or it’s great for game day as well.

The best part is that there are so many ways to customize it to exactly how you want it. Let’s learn how to make this easy casserole recipe with tons of tips, variations, and ideas to make it uniquely your own for your family ❤︎

How To Make Walking Taco Bake (Printable Recipe Card)

Preheat the oven to 375°F. Lightly spray a 9×13-inch casserole dish with nonstick cooking spray. 

Pour about 3/4 of the bag of Fritos into the bottom of the baking dish and spread them out into an even layer. Reserve the rest for a crunchy topping for serving. 

In a large skillet, over medium-high heat, cook and crumble the ground beef until it’s no longer pink. Drain excess grease from the skillet. 

Add the packet of taco seasoning and water into the skillet. Bring the mixture to a low boil and then reduce to medium heat, and let it simmer for about 5 minutes or until thickened. 

Stir in the pinto beans and Rotel until combined and let simmer for 5 minutes. When done, remove the skillet from the heat. 

Sprinkle 1 cup of shredded cheese over top the layer of chips inside the casserole dish. Spoon the hot taco meat mixture over top the cheese in an even layer. Spread gently so the chips and cheese mostly stay in the same place. 

Sprinkle the remaining 1 cup shredded cheese evenly over top the ground beef mixture. 

Bake uncovered for 18-22 minutes or until the cheese is fully melted and bubbly around the edges. 

Remove from the oven and let the casserole rest for 5 minutes to set slightly. Top the casserole with the remaining Fritos chips, shredded lettuce, diced tomato, sliced jalapeños (if using), dollops of sour cream, and any other favorite toppings. Enjoy! You can top the entire casserole with the toppings or top individual servings instead. 

How To Store and Reheat Leftover Walking Taco Casserole 

Keep leftovers stored in the refrigerator, covered in the pan or remove individual servings to an airtight container, for up to 3 days. I recommend keeping the extra Fritos stored separately and not on top of the casserole in the fridge. 

You can reheat portions of the leftover casserole in the microwave for 1-2 minutes or untiled heated through. I prefer scraping off the toppings before microwaving, and then adding them back on the warmed leftovers. 

Substitutions and Ingredient Notes

• Ground Beef : Ground turkey or ground chicken is another option.
• Taco Seasoning : I like the mild taco seasoning but you can use regular, spicy, cheesy, low-sodium, etc.
• Pinto Beans : Any canned bean that has been drained and rinsed can be used in this recipe; black beans, navy beans, chili beans, ranch style beans, or refried beans (you can’t drain these but they will still work in the recipe, just simmer for a bit longer).
• Rotel : I use the mild version but feel free to spice it up and use the medium or hot Rotel tomatoes. If you want no spice at all then use a can of petite diced tomatoes.
• Fritos : Use the chili cheese Fritos for mild kick and flavor, or stick with original Fritos (this is what I use). Other options are Doritos or tortilla chips.
• Shredded Cheese : I use medium cheddar cheese but any shredded cheese can be used – Mexican blend cheese, pepper jack, Monterey Jack, or a fiesta blend cheese.

Pro Tips From The Test Kitchen

• Let the beef mixture simmer as needed until it’s thickened and not to runny/saucy. If it looks watery then give it more time. You want to remove as much moisture as possible to prevent the casserole and chip layer from being too soggy and wet.
• Draining and rinsing the beans removes excess starch and sodium, which keeps the filling from becoming too wet. Draining the Rotel helps control moisture, so the casserole stays thick and scoopable rather than water, especially since the Fritos form the base. 
• If you prefer more spice then try some of these ideas; use hot taco seasoning, use Pepper Jack shredded cheese, use a can of hot Rotel tomatoes, and choose spicier toppings such as jalapeños with seeds intact or pickled jalapeños. Other options are to add some spicier dried seasonings such as chili powder, cayenne pepper, or chipotle seasoning.
