Store-bought fajita seasoning packets are not only expensive, they often contain fillers and carry a risk of gluten cross-contamination. This quick and easy homemade gluten-free fajita seasoning recipe is made with simple pantry spices, safe for kids, and ready in minutes.

Two tablespoons equal one packet – perfect for chicken fajitas, beef, shrimp, or even veggie fajitas.

It’s full of flavour but gentle enough for kids, making it the best fajita seasoning recipe for families.

Ingredients Required to Make Gluten-Free Fajita Seasoning Mix

Here’s what you’ll need to make about ⅔ cup of seasoning (10 packet-equivalents):

2 tablespoons + 2 teaspoons (18g) chili powder (gluten-free certified)
2 tablespoons (14g) smoked paprika (or regular paprika)
2 tablespoons (12g) ground cumin
2 tablespoons (18g) garlic powder
2 tablespoons (18g) onion powder
1 tablespoon (4g) dried oregano
2 teaspoons (4g) ground coriander (optional)
2 teaspoons (10 – 12g) salt
1 teaspoon (2g) ground black pepper
½ teaspoon (1g) cayenne pepper (optional – leave it out if your kids don’t like spice, as even a little can make the mix quite hot).

👩‍👧 Kid-Friendly Note

Cayenne pepper is what really adds heat in this mix. Even a small amount can make fajitas too spicy for most kids. If your kids prefer milder flavors, leave it out entirely or keep just a tiny pinch for warmth without the burn.

How to Make Gluten-Free Fajita Seasoning

Add all ingredients to a small mixing bowl.
Stir or whisk until evenly combined.
Transfer to an airtight jar or container. Store in a cool, dry place for up to 6 months.

How to Use This Homemade Fajita Seasoning

2 tablespoons = 1 store-bought packet
Cook with 1 lb (450g) of chicken, beef, shrimp, or veggies.
For saucier fajitas, add 2–3 tablespoons of water and a drizzle of oil when cooking with the spice mix.

These spices work beautifully for chicken fajitas, beef fajitas, shrimp fajitas, or veggie fajitas – so it’s a really versatile seasoning blend you’ll always want in your pantry.

Substitutions & Alternatives

Mild for kids: Skip cayenne and halve the chili powder.
No chili powder? Use extra paprika with a pinch more cumin.
Low-salt option: Leave out the salt and season to taste at the end.
Herby twist: Add thyme or parsley for extra fragrance.
