Walking Taco Casserole is a 30-minute hearty and delicious Tex-Mex meal. Everything you love about classic beef tacos is baked into this kid-friendly Frito casserole! It’s simple to make, and a fun dinner idea for Taco Tuesdays or Cinco de Mayo.

Have you ever been to a county or state fair, and noticed people eating food out of a single serving bag of Fritos or Doritos? Well, they were enjoying walking tacos!
A walking taco is a delicious portable meal that is eaten right from a bag of corn chips. Along with the chips is a serving of taco-seasoned ground beef and usually, diced tomatoes and shredded cheese.
This walking taco bake puts a casserole twist on that fabulous fair food. But the best part of this dish is, there’s plenty of room for extra toppings, and it makes enough to feed six people, not just one!

Why We Love Walking Taco Casserole
- Quick, easy, and fun!
Making this recipe is easy, and if you have kids or grandkids, they can help assemble the layers into the pan.
- Can be made ahead for busy nights.
If your family is constantly on the go, this beef taco bake will save you a lot of time on busy nights.
Make it when you have a few spare minutes. Then, pop it in the freezer (without the chips) and it will keep for up to 4 months!

INGREDIENT Notes + Substitutions
- Lean Ground Beef – To prevent this dish from being greasy, we recommend using a lean blend of hamburger meat.
85/15 is a great choice because there is some fat (which adds flavor), but not so much that the grease soaks into the other casserole ingredients.
- Shredded Mexican Cheese – Because this is a Tex-Mex dish, we use a blend of Mexican cheeses.
Pre-shredded cheese is the most convenient, but if you can afford it, buy a block of cheese and shred it yourself. Freshly shredded cheese melts better than the packaged shreds, and it tastes better, too!

Tips for Making a Fabulous Taco Bake
- Break up the taco meat as it cooks.
If you have big clumps of ground beef in the casserole, you’ll end up with pieces that don’t have enough seasoning.

- Let the mixture simmer until the pan is almost dry.
When you add the canned tomatoes to the skillet, there will be a lot of liquid. Simmer the mixture long enough for that liquid to cook off. This will prevent your taco bake from being wet and runny.

- Don’t be shy with the cheese!
Sprinkle 1/2 cup cheese over the taco casserole mixture. Scatter the Fritos over the that, then top it off with the remaining 1/2 cup cheese.

- Bake until the filling is bubbly and golden brown.
It’s important to cook your taco bake long enough to melt all of that wonderful cheese.

Walking Taco Casserole FAQ
Unlike a traditional walking taco, which is taco seasoned beef and toppings eaten from a bag of corn chips, both Frito pie and walking taco casserole are baked dishes.
The ingredients are nearly identical, but some versions of Frito pie include a crust.
Use your favorite taco toppings to jazz up the casserole. Good choices are diced avocado, pico de gallo, jalapenos, and sour cream.
Make Ahead Instructions
Fritos (and similar corn tortilla chips) quickly soak up any liquids that are nearby, and then they become mushy.
So, to make the walking taco bake ahead for a freezer meal to bake later, it’s important to assemble the casserole without the chips. Make the recipe up to step 4, as written in the recipe card, below.
Then, a couple of days before you want to cook the meal, transfer the dish to the fridge so it can thaw out.
When it is thawed, add the chips and cheese. Then, cover the dish and bake in a 350°F. oven for 45 minutes, removing the foil for the final 15 minutes of cook time.

Instructions

I confused where is the hot sauce coming from?
Bec @ The Feathered Nester says
Hi Cathy,
I’m sorry for the confusion. What we’re referring to are the reserved juices from the can of Rotel tomatoes. Some people are unable to find that product in their area, so in the notes,we mention using hot sauce as a substitute.
