Ingredients
Method
- Measure your spices: Add all ingredients to a small bowl. Level off each measurement for consistency.
- Whisk to combine: Use a fork or small whisk to break up any clumps and blend everything evenly.
- Taste and adjust: Pinch a tiny amount and taste. Add more salt for savoriness, cumin for earthiness, paprika for sweetness/smoke, or cayenne for heat.
- Store properly: Transfer to a clean, dry, airtight jar. Label with the date and spice blend name.
- Use it: For fajitas, use about 1 to 1.5 tablespoons per pound of protein. Add a squeeze of lime and a splash of avocado oil when cooking for classic sizzle.
What Makes This Recipe So Good

- Truly keto-friendly: No added sugars or starches, and you control the sodium.
- Big flavor, simple ingredients: Chili powder, cumin, smoked paprika, garlic, onion—classic fajita notes with a smoky edge.
- Budget-friendly and flexible: Cheaper than store-bought packets and easy to tweak for heat or smokiness.
- Meal-prep friendly: Make a larger batch and season proteins or veggies throughout the week.

Ingredients
- 2 tablespoons chili powder
- 1 tablespoon ground cumin
- 1 tablespoon smoked paprika (or sweet paprika if you prefer)
- 2 teaspoons garlic powder
- 2 teaspoons onion powder
- 1 teaspoon dried oregano
- 1 teaspoon fine sea salt (adjust to taste)
- 1 teaspoon freshly ground black pepper
- 1/2 to 1 teaspoon crushed red pepper flakes (optional, for heat)
- 1/4 teaspoon cayenne pepper (optional, for extra kick)
- 1/2 teaspoon lime zest powder or citric acid (optional, for a tangy note)
How to Make It

- Measure your spices: Add all ingredients to a small bowl. Level off each measurement for consistency.
- Whisk to combine: Use a fork or small whisk to break up any clumps and blend everything evenly.
- Taste and adjust: Pinch a tiny amount and taste.
Add more salt for savoriness, cumin for earthiness, paprika for sweetness/smoke, or cayenne for heat.
- Store properly: Transfer to a clean, dry, airtight jar. Label with the date and spice blend name.
- Use it: For fajitas, use about 1 to 1.5 tablespoons per pound of protein. Add a squeeze of lime and a splash of avocado oil when cooking for classic sizzle.
Keeping It Fresh
- Use an airtight container: A glass spice jar with a tight lid keeps aroma and potency intact.
- Avoid heat and light: Store in a cool, dark cabinet—no sunlight or stovetop proximity.
- Mind the moisture: Always use a dry spoon.
Moisture leads to clumping and dull flavor.
- Best-by guideline: For peak flavor, use within 6 months. It won’t “go bad” quickly, but spices lose their punch over time.

Benefits of This Recipe
- Low-carb and sugar-free: Keeps carbs minimal for keto, unlike some store blends with sugar or cornstarch.
- Clean ingredients: No anti-caking agents or additives—just real spices.
- Customizable: Adjust heat, salt, and smokiness to fit your taste and diet.
- Time-saving: Pre-mixed seasoning makes fast dinners even faster.
- Versatile use: Season fajitas, taco bowls, eggs, roasted cauliflower, or grilled shrimp.
What Not to Do
- Don’t skip the salt entirely unless you need to. A small amount wakes up all the other flavors.
- Don’t store near steam (like above the stove).
Steam causes clumping and weakens the spices.
- Don’t use stale spices: If your chili powder smells flat or dusty, your blend will taste bland.
- Don’t overdo the heat on your first batch. Start with less cayenne and adjust next time.
- Don’t rely on this alone for “sizzle”: The sear comes from hot oil and a hot pan. The seasoning provides flavor, not char.
Variations You Can Try
- Citrus-forward: Add 1/2 teaspoon citric acid or extra lime zest powder for a tangy finish.
- Chipotle smoky: Swap half the smoked paprika for ground chipotle chili for deeper heat and smoke.
- Herby twist: Add 1/2 teaspoon coriander and 1/2 teaspoon thyme for a bright, aromatic edge.
- Salt-free: Skip the salt if you’re watching sodium and season the finished dish to taste.
- Mild family version: Omit cayenne and red pepper flakes; rely on smoked paprika for warmth without the burn.
- Tex-Mex taco crossover: Add 1/2 teaspoon ground coriander and a pinch of cinnamon for a taco-style blend that still works for fajitas.
FAQ
How much seasoning should I use per pound of meat?
Use about 1 to 1.5 tablespoons per pound.
If your meat is very thick or you like bolder flavor, go up to 2 tablespoons and taste as you cook.
Is this seasoning spicy?
It’s moderately spiced by default. The heat comes from red pepper flakes and cayenne, which you can reduce or omit for a mild version.
Can I use this for vegetables only?
Absolutely. Toss sliced bell peppers, onions, and zucchini with avocado oil and 1 tablespoon of seasoning, then roast or sauté until tender and slightly charred.
What’s the best oil to use for keto fajitas?
Avocado oil is ideal because it has a high smoke point and a neutral flavor.
Ghee also works well for rich, buttery notes.
Can I turn this into a marinade?
Yes. Mix 1.5 tablespoons seasoning with 2 tablespoons avocado oil and 1 tablespoon lime juice per pound of protein. Marinate 20–30 minutes, then cook hot and fast.
Is this gluten-free?
Yes, as written it’s naturally gluten-free.
Just confirm your individual spice brands if you’re highly sensitive to cross-contamination.
How long does it last?
For best flavor, use within 6 months. It’s still safe after that, but the aroma and intensity fade.
What if I don’t have smoked paprika?
Use sweet paprika and add a pinch of ground chipotle or a drop of liquid smoke to the pan while cooking. Or simply keep it classic with regular paprika.
