You sure can. Taco seasoning is just a mixture of spices. If you're making your own, we would recommend trying: 1 tablespoon chili powder 1 teaspoon cumin 1 teaspoon paprika 1/2 teaspoon onion powder 1/2 teaspoon garlic powder 1/2 teaspoon of salt (to your preference) 1/4 teaspoon oregano and a pinch of red pepper flakes (if you like spice, add more) A package of taco seasoning mix usually has about 2 tablespoons in it, so once you've combined your spices together well you can use 2 tablespoons in this easy chicken taco bake recipe and save the rest in an airtight container for later!
