Can I grill the chicken instead?
Absolutely! Grilling adds a nice smoky flavor. Cook over medium-high heat for about 4-5 minutes per side.
🛒Ingredients
- Chicken breast – I love using chicken breast for this because it’s lean, cooks quickly, and soaks up all the marinade flavors beautifully. Slice it into ½-1 inch strips so everything cooks evenly.
- Bell peppers – Go for tricolor peppers if you can! The mix of red, yellow, and green adds a lovely sweetness and makes the fajitas look extra vibrant.
- Brown onion – Caramelizes beautifully in the pan, adding just the right amount of sweetness to balance out the spice.
- Lime juice – A must! It gives everything a fresh, zesty kick and tenderizes the chicken.
- Cumin – Warm and earthy, this is what makes fajitas taste like fajitas!
- Smoked paprika – Adds a subtle smokiness that makes you feel like you grilled everything over an open flame. If you only have regular paprika, that works too.
- Garlic – Freshly minced for the best flavor. No jarred stuff here!
- Cayenne & chili powder – Adjust depending on your spice tolerance. I like a little heat, but you can dial it back if you prefer.
- Salt & pepper – Brings out all the flavors and ties everything together.
- Olive oil – Helps the marinade coat everything evenly and keeps the chicken juicy.
- Crushed red chili flakes – Totally optional, but if you love extra heat, go for it!
- Small tortillas – Warm them up before serving! A quick toast on a dry skillet makes them soft and pliable.

🥘 How To Make Chicken Fajitas
- Prep the veggies – cut bell peppers and onions into ½-inch thick strips.
- Make the marinade – in a large bowl, whisk together lime juice, cumin, smoked paprika, garlic, cayenne, chili powder, salt, pepper, olive oil, and red chili flakes.
- Marinate the chicken – toss chicken strips with 2 heaping tablespoons of marinade. Cover and refrigerate for 20-30 minutes.
- Coat the veggies – toss the sliced peppers and onions with the remaining marinade.
- Cook the veggies – heat a large skillet over medium-high heat with a little oil. Sauté peppers and onions until soft but still crisp. Set aside.
- Cook the chicken – in the same pan, cook the chicken 2-3 minutes per side until golden brown and cooked through.
- Combine & serve – return veggies to the pan, mix well, and drizzle with lime juice. Serve hot in tortillas with your favorite toppings!
Can I use chicken thighs instead of breasts?
Yes! Chicken thighs are juicier and add extra flavor.
📋Tips
- What’s the best way to warm tortillas? Toast them on a dry skillet for a few seconds per side or microwave them wrapped in a damp towel.
- For juicier chicken – let it marinate at least 30 minutes (or overnight for extra flavor). However, you can cook the fajitas right away in just 15 minutes, too (still flavorful!)
- Don’t overcook – thin chicken strips cook quickly! Remove them as soon as they are golden brown.
- Use a cast iron skillet – helps get that perfect char on the chicken and veggies.
- Swap proteins – try shrimp, beef, or tofu for a variation.
- Make it low-carb – serve over a salad or in lettuce wraps instead of tortillas.
- Add more veggies – mushrooms or zucchini work great too!
- Use store-bought seasoning – if you’re in a hurry, a fajita seasoning mix works well.
🍱Storage Instructions
- 🍱To Store. Keep in an airtight container in the fridge for up to 4 days.
