Dry spices, including chili powder, garlic, onion, paprika, cayenne pepper, crushed red pepper, cumin and salt, blend together well, creating an easy homemade fajita seasoning mix. Use the mix immediately, or add a small amount of cornstarch to it to prevent stored fajita seasoning from clumping or absorbing moisture.
Combine 1/4 cup of chili powder with 1 tablespoon of each of the following spices: cumin, onion powder and garlic powder. Mix in 2 tablespoons of sea salt, 2 tablespoons of paprika and 1 teaspoon of cayenne pepper. The ratios can be adjusted to taste. Optional extra ingredients include crushed red pepper flakes for added heat, sugar for a touch of sweetness and crushed bouillon cubes for depth.
Cooks can also marinate fajita ingredients instead of using a dry rub. For example, combine 1/2 cup of olive oil with 3 tablespoons of Worcestershire sauce, soy sauce, steak sauce or hot sauce. Mix in 1/3 cup of fresh lime juice, 3 or 4 cloves of minced garlic and dry seasonings, including 1 teaspoon of salt, 1/2 teaspoon of black pepper, 1 tablespoon of sugar, 1 tablespoon of cumin, 1 tablespoon of chili powder and 1/2 teaspoon of red pepper flakes. Allow the meat or veggies to marinate in the refrigerator in a covered dish or resealable bag for two hours or longer, according to a beef fajita recipe on ThePioneerWoman.com.
