Weeknight dinners don’t need to be complicated to be satisfying. These sizzling chicken fajitas bring bold flavor, juicy chicken, and tender-crisp veggies to your table in under 40 minutes. You can make them on a sheet pan for minimal cleanup or in a skillet for that charred, restaurant-style sear.
Either way, they’re fresh, colorful, and endlessly customizable. Set out warm tortillas and your favorite toppings, and dinner practically serves itself.
Why This Recipe Works
- Two cooking methods, same great result: The sheet pan version is hands-off, while the skillet version gives rich caramelization. Both produce tender, flavorful chicken and vibrant peppers.
- Quick marinade with pantry spices: Chili powder, cumin, and smoked paprika deliver authentic fajita flavor without a long marinating time.
- Thin slicing = fast cooking: Cutting chicken and vegetables into similar sizes ensures everything cooks evenly and quickly.
- Flexible and forgiving: Use chicken thighs or breasts, swap peppers, or add mushrooms or zucchini.
It all works.
- Perfect for meal prep: The leftovers reheat well, and the components can be prepped in advance.
Ingredients
- 1.5 pounds boneless, skinless chicken (breasts or thighs), sliced into thin strips
- 3 bell peppers (any colors), sliced into thin strips
- 1 large red onion, thinly sliced
- 2–3 tablespoons olive oil
- 2 teaspoons chili powder
- 1.5 teaspoons ground cumin
- 1 teaspoon smoked paprika (or sweet paprika)
- 1 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/2 teaspoon dried oregano
- 1/4–1/2 teaspoon cayenne pepper (optional, to taste)
- 1 teaspoon kosher salt, plus more to taste
- 1/2 teaspoon black pepper
- Zest and juice of 1 lime
- 8–12 small flour or corn tortillas, warmed
- Optional toppings: sliced avocado, guacamole, sour cream or Greek yogurt, salsa, pico de gallo, shredded cheese, chopped cilantro, extra lime wedges
Step-by-Step Instructions
- Prep the produce: Thinly slice the bell peppers and red onion. Pat the chicken dry, then slice into thin strips, about 1/2 inch wide.
- Make the seasoning blend: In a small bowl, combine chili powder, cumin, smoked paprika, garlic powder, onion powder, oregano, cayenne (if using), salt, and black pepper.
- Season and marinate: In a large bowl, toss the chicken with half the oil, half the seasoning blend, and half the lime zest and juice. In another bowl, toss the peppers and onions with the remaining oil and seasoning.
Let sit 10–20 minutes while you heat the oven or skillet.
- Choose your method:
- Sheet pan: Preheat oven to 425°F (220°C). Arrange peppers and onions on a large sheet pan in a single layer. Scatter chicken on top, leaving space between pieces.
- Skillet: Heat a large cast-iron or stainless-steel skillet over medium-high until very hot.
Add a drizzle of oil. Cook chicken in batches, 3–4 minutes per side, until browned and cooked through. Remove and set aside.
Sauté peppers and onions until tender-crisp with some char, about 5–7 minutes. Return chicken to the pan, add remaining lime juice and zest, and toss.
- Bake (sheet pan method): Roast 18–22 minutes, stirring halfway, until chicken is cooked through (internal temp 165°F/74°C) and vegetables are tender with a little color. For extra char, broil 1–2 minutes at the end, watching closely.
- Taste and adjust: Squeeze on more lime, add a pinch of salt if needed, and toss everything to coat.
If you like it saucier, add a splash of chicken broth or a teaspoon of honey mixed with lime for gloss and balance.
- Warm the tortillas: Wrap in foil and warm in the oven for 5 minutes, or toast directly over a gas flame for a few seconds per side until lightly charred and pliable.
- Serve: Pile the chicken and veggies into warm tortillas. Add your favorite toppings, and finish with fresh cilantro and a squeeze of lime.
Storage Instructions
- Refrigerate: Store cooled chicken and vegetables in an airtight container for up to 4 days.
- Freeze: Freeze portions in freezer-safe bags for up to 2 months. Thaw overnight in the fridge before reheating.
- Reheat: Warm gently in a skillet over medium heat with a splash of water or broth, or microwave in 30-second bursts, just until hot to avoid drying out.
- Tortillas: Store separately.
Re-warm right before serving for best texture.

Pitfalls to Watch Out For
- Overcrowding the pan: Crowded skillet or sheet pan = steaming instead of searing. Use a large pan or cook in batches.
- Uneven slicing: Thick pieces take longer and can overcook the thinner ones. Aim for uniform strips.
- Skipping the salt or acid: Fajitas need enough salt and a bright hit of lime.
Taste and adjust before serving.
- Overcooking chicken: Pull it at 165°F (74°C). Dry chicken is the quickest way to ruin great spices.
- Cold pan for skillet method: If the pan isn’t hot, you won’t get that signature char. Preheat thoroughly.
Alternatives
- Protein swaps: Use steak (skirt or flank, thinly sliced), shrimp (cook 2–3 minutes per side), or tofu (press and slice into slabs, then strips).
Portobello mushrooms make a hearty vegetarian option.
- Low-carb or gluten-free: Serve over cauliflower rice or salad greens, or use corn tortillas or lettuce wraps.
- Different veggies: Try poblano peppers, mushrooms, zucchini, or cherry tomatoes. Add at the right time so they don’t overcook.
- Flavor twists: Add a teaspoon of chipotle in adobo for smoky heat, or swap lime for a splash of orange juice for a Tex-Mex vibe.
- Dairy-free creaminess: Top with avocado, guacamole, or a drizzle of cashew crema instead of sour cream.
FAQ
Can I make the marinade ahead of time?
Yes. Mix the oil, spices, lime zest, and juice up to 3 days in advance and store in a jar in the fridge.
Toss with chicken and veggies 10–20 minutes before cooking.
How do I keep the peppers from getting soggy?
Slice them thin but not paper-thin, don’t overcrowd the pan, and cook over high heat. In the oven, use a hot sheet pan and consider a brief broil at the end for extra char.
What’s the best cut of chicken for fajitas?
Chicken thighs stay juicy and forgiving, but chicken breasts also work well when sliced thin and cooked quickly. The seasoning and lime keep both tender and flavorful.
How spicy are these fajitas?
Mild to medium.
The base spice blend is warm but not hot. Add cayenne or fresh jalapeño to increase heat, or skip the cayenne for a kid-friendly version.
Can I double the recipe?
Absolutely. Use two sheet pans and rotate them halfway through, or cook in skillet batches so everything sears instead of steams.
What sides go well with fajitas?
Spanish rice, cilantro-lime rice, black or pinto beans, corn salad, or a simple green salad all pair nicely.
Chips and salsa or guacamole are always welcome.
How do I warm tortillas so they stay soft?
Wrap in foil and heat in a 300°F oven for 8–10 minutes, or warm in a dry skillet 20–30 seconds per side. Keep them stacked and wrapped in a clean towel to retain heat.
