Place them in a bowl and add:
- Smoked paprika
- Cumin
- Chili powder
- Garlic powder
- Onion powder
- Oregano
- Salt
- Black pepper
- Olive oil
Toss until the chicken is evenly coated.
Step 2: Prepare the Vegetables
Slice the bell peppers and red onion into thin strips.
Keep the vegetables roughly the same size so they cook evenly.
Step 3: Cook the Chicken
Heat a large skillet over medium-high heat.
Add the seasoned chicken and cook for approximately 6–8 minutes, turning occasionally.
The chicken should be golden on the outside and cooked through.
Transfer the chicken to a clean plate.
Step 4: Cook the Peppers and Onion
Add another tablespoon of olive oil to the skillet.
Add the sliced peppers and onion.
Cook for approximately 6–8 minutes, stirring occasionally.
The vegetables should become tender while developing lightly charred edges.
Step 5: Add the Garlic
Add the minced garlic.
Cook for about 30–60 seconds, stirring constantly.
Be careful not to burn it.
Step 6: Combine Everything
Return the cooked chicken to the skillet.
Toss everything together and cook for another 1–2 minutes.
Squeeze fresh lime juice over the chicken and vegetables.
Taste and add additional salt or chili powder if desired.
Step 7: Warm the Tortillas
Warm the tortillas in a dry skillet for approximately 20–30 seconds per side.
Alternatively, wrap them in foil and warm them in the oven.
Step 8: Serve
Place the chicken and vegetables inside the warm tortillas.
Top with avocado, salsa, cilantro, and any other dairy-free toppings you enjoy.
Serve with fresh lime wedges.
Tips for the Best Chicken Fajitas
- Slice the chicken evenly so it cooks at the same rate.
- Don’t overcrowd the skillet.
- Cook the vegetables over fairly high heat for lightly charred edges.
- Use fresh lime juice for the best flavor.
- Warm your tortillas before serving.
- Add toppings just before eating for the best texture.
The key is cooking the chicken and vegetables quickly over relatively high heat. This keeps the chicken juicy while giving the vegetables delicious caramelized edges.

How to Store Dairy-Free Chicken Fajitas
In the Refrigerator
Store the cooked chicken and vegetables in an airtight container for up to 3 days.
Keep tortillas and toppings separate.
Reheating
Reheat the chicken and vegetables in a skillet over medium heat until warmed through.
Freezing
The cooked chicken and vegetables can be frozen for up to 3 months.
Allow them to thaw in the refrigerator before reheating.
For the best texture, add fresh toppings after reheating.
Common Mistakes to Avoid
Overcrowding the Pan
Too much food in the skillet can cause the chicken and vegetables to steam instead of brown.
Cutting the Chicken Too Thick
Thick pieces take longer to cook and can become dry on the outside before the center is ready.
Burning the Spices
Keep an eye on the skillet when cooking the seasoned chicken.
Overcooking the Vegetables
Fajita vegetables are best when they’re tender but still have some bite.
Forgetting the Lime
Fresh lime juice adds acidity that balances the smoky spices.

Why These Chicken Fajitas Are So Flavorful
The secret is the homemade fajita seasoning.
Smoked paprika provides a subtle smoky flavor, while cumin adds warmth and depth. Chili powder brings mild heat, and garlic and oregano round everything out.
Cooking the chicken separately from the vegetables also allows both ingredients to brown properly instead of releasing too much moisture into the pan.
Finally, fresh lime juice brings everything together and keeps the dish tasting fresh rather than heavy.
