Homemade Taco Seasoning Recipe

Mix the following taco seasoning ingredients in a bowl and store in an airtight container in the pantry or a cool cupboard.  Makes about 3/4 cup.  Use 3 to 4 Tablespoons as a substitute for store bought taco seasoning.

  • 1/2 cup nutritional yeast
  • 2 teaspoon garlic powder
  • 2 teaspoon onion powder
  • 2 teaspoon cumin
  • 2 teaspoon paprika
  • 2 teaspoon chili powder
  • 4 teaspoons salt


I love sour cream on this dish before any other toppings.  It’s hard to spread sour cream over corn chips, though, so I put the sour cream in a piping bag and pipe it onto the walking taco casserole.

If taking walking taco casserole to a potluck or covered dish supper, wait to add the Fritos corn chips, sour cream and toppings until just before serving.

If you are planning leftovers, serve Fritos corn chips and toppings on the side, so everyone can customize the toppings on their own individual servings.  Store the baked casserole in an airtight container in the fridge for up to 4 days.  Reheat leftovers in microwave or oven.  Then serve with corn chips, sour cream and toppings on the side.

To freeze walking Taco Casserole, complete the recipe through step 8. Seal the pan with plastic wrap and then with aluminum foil. Store it in the freezer for up to 4 months. To bake the frozen casserole, thaw it in the fridge overnight and then bake and top according to the recipe. (Baking times straight from the fridge will be a little longer.)
