What are Walking Tacos?

Walking tacos are an easy, customizable way to enjoy taco fillings served in a chip container. Traditionally, you fill a single-serving bag of Doritos or Fritos with seasoned ground beef, shredded lettuce, diced tomatoes, shredded cheese, salsa, sour cream, and hot sauce, then eat from the bag with a fork. This casserole captures those same flavors in a 9×13-inch pan for a shareable, fork-and-plate friendly version.

I grew up enjoying a version of this dish my mom called “taco salad.” This casserole keeps the familiar flavors but presents them as a warm, shareable meal rather than a salad or individual chip bags.

All of the ingredients needed to make walking taco casserole recipe in individual measuring cups and ramekins.

Key Ingredients and Substitutions

See the recipe card below for exact measurements.

  • Ground beef: Lean ground beef works well here. Substitute ground turkey or chicken for a lighter option.
  • Chicken broth: Used to simmer the seasoned beef and keep it moist; beef broth works too.
  • Taco seasoning: Use a favorite store-bought mix or homemade seasoning. Adjust spice level to taste.
  • Nacho cheese sauce: A simple homemade sauce made from a roux (butter + flour), milk, chili powder, salt, and shredded cheddar and Monterey Jack melts into a smooth, creamy topping.
  • Fritos and Doritos: The recipe uses both for texture and flavor, but you can swap Fritos for tortilla chips or use only one chip type if preferred. Fritos add a distinct corn flavor.
  • Toppings: Classic choices include shredded iceberg lettuce, diced tomatoes, red onion, sour cream, and hot sauce. Optional extras: avocado or guacamole, pico de gallo, black olives, pickled jalapeños, and green onions.

How to Make Walking Taco Casserole

1. Preheat the oven to 350°F and spray a 9×13-inch baking dish with non-stick spray.

2. Brown and season the meat: In a large skillet over medium-high heat, crumble and brown the ground beef. Drain excess fat, then stir in chicken broth and taco seasoning. Cook until the broth evaporates, then remove from heat.

Slowly whisk in milk and bring to a gentle simmer, whisking until thickened. Remove from heat and stir in shredded cheddar and Monterey Jack a handful at a time until smooth.

Storage and Reheating

Let leftovers cool completely before covering tightly or transferring to an airtight container. Store in the refrigerator for 3–4 days. To freeze, use a freezer-safe container and keep up to 3 months. Thaw overnight in the refrigerator before reheating. Note: the cheese sauce can change texture slightly after freezing and reheating; reheat gently to restore creaminess.
