why this recipe works

So, what makes this fajitas seasoning blend "keto diet friendly"?

Homemade fajita seasoning features simple ingredients from your spice cabinet and is also free of any questionable additives, dyes and ingredients (like maltodextrin, which is commonly found in store-bought fajita seasonings).

This keto fajita seasoning recipe includes all the spices that bring big flavor. Plus, we're using a little bit of granulated golden monk fruit sweetener for a touch of sweetness to keep this spice mix sugar-free and low in net carbs.

Our homemade fajita spice blend is:

• easy to make and ready in minutes
• versatile and simple to modify to your own taste preferences
• the perfect, multi-use spice mix for a variety of dishes
• a sugar-free, low-carb and gluten-free seasoning spice mix

ingredients for low-carb fajita seasoning

This homemade seasoning is ready in just five minutes and it requires less than 10 ingredients.

To make it, you will need:

• salt
• black pepper
• garlic powder (or garlic granules)
• onion powder
• ground cumin
• chili powder
• ground coriander
• optional chipotle powder, adobo chili powder or cayenne pepper if you want an extra kick
• granulated monk fruit sweetener - I like Lakanto's Golden or Brown sweetener (affiliate links) but feel free to use your favorite sugar substitute.

The chipotle powder, adobo chili powder and cayenne pepper are great options if you want to give this homemade fajita seasoning mix a bit more heat.

Without it, the spice level is pretty mild. A bit of chipotle powder or ground cayenne pepper will up the spiciness to a medium high heat.

a five-minute keto fajita seasoning recipe

I love a good homemade spice blend or dry rub recipe, mostly because they're so simple to make and just five minutes of prep will set you up with an easy blend to use for several different meals.

Make sure you have an airtight container to store the seasoning mix. A mason jar, glass canister, empty spice bottle or even a plastic bag (I use a Stasher bag, pictured below) are good storage options for keeping the low carb fajita seasoning fresh and dry.

tips for the best results

• This keto fajitas seasoning is what I use in my keto chicken fajitas recipe. I marinade the chicken with olive oil, lime juice and lemon juice along with a tablespoon of this spice mix, and I also stir it in with the bell peppers and onions while they sauté. You can use it in the same way for a beef-based fajitas recipe with skirt steak or flank steak.

• The sweetener is entirely optional. Feel free to leave it out if you are looking for more of a traditional taco seasoning.

• As I mentioned above, this low-carb fajita seasoning blend can be modified to fit your own taste preference. For a medium-high heat, make sure to use a touch of ground pepper like cayenne, chipotle powder or adobo chili powder.

• Taste the spice mix after all of the ingredients are well combined. This will help you determine whether it needs more salt, spice or even sweetness.

• This sugar free fajita seasoning recipe will keep well for four to six months when stored in an airtight container in a cool, dry place.
