Chicken fajita tacos soak up a punchy lime-and-spice marinade, then sizzle with sweet peppers and onions for a taco night that smells like your favorite Tex-Mex grill. Pile the juicy strips into warm tortillas and watch them disappear.
If you’ve tried our saucy ground beef tacos or the melty cheese pull of street corn quesadillas, you’ll love how these fajita-style tacos turn humble chicken into a fast week-night feast. They’re bright, colorful, and ready for every topping in your fridge.
Cooking fajitas at home is easier than it looks. The marinade mixes in one bowl, the veggies cook while the chicken rests, and everything comes together in the same skillet—so clean-up is low stress. Plus, one batch makes six hearty tacos, but the seasoned chicken keeps well for salads, burrito bowls, or quesadillas later in the week.
Why This Recipe Works
Lime Marinade Tenderizes and Flavors. A short bath of lime juice, olive oil, and warm spices loosens the chicken’s fibers so it stays moist on the stove. The acid also wakes up dried herbs like oregano and cumin, giving every bite bright flavor that rivals a restaurant sizzling platter.
High-Heat Sear Creates Char Without a Grill. Cooking the peppers first lets the skillet reach a steady heat. When the chicken hits the pan, the surface is hot enough to caramelize the spices in seconds, forming tasty brown edges while the inside stays juicy.
One-Pan Method Saves Time and Dishes. Vegetables sauté first, then rest on a plate while the chicken cooks in their seasoned oil. The veggies go back in at the end to warm through, so you get full fajita flavor with only one pan to wash.
Flexible Serving Options Keep Leftovers Exciting. Leftover filling works in quesadillas, taco salads, or breakfast burritos. Because the marinade is mild-medium, it pairs just as well with scrambled eggs the next morning as it does with tortillas tonight.
Ingredients & Substitutions
- Chicken Breasts (1½ lb, thin strips) – Thighs add extra richness if you prefer dark meat.
- Marinade – Olive oil, lime juice, oregano, cumin, garlic powder, smoked paprika, onion powder, chili powder, salt, pepper, and a pinch of red pepper flakes for heat. Swap fresh lime for bottled only in a pinch; fresh juice gives brighter flavor.
- Bell Peppers – A mix of red and green adds color and sweetness. Yellow or orange peppers are fine substitutes.
- Onions – Red onion brings mild sweetness; green onions add freshness. A white onion can stand in if that’s what you have.
- Flour Tortillas (6, 8-inch) – Corn tortillas work but may tear; use two stacked if you go that route.
- Toppings – Shredded cheddar, salsa, guacamole, taco sauce, sour cream. Pick your favorites or set up a DIY bar.
Expert Tips
- Slice Chicken Evenly for Fast, Even Cooking. Aim for ½-inch thick strips. When pieces are uniform, they cook in the same amount of time, so you avoid over-done ends and under-done centers. A quick freeze (15 minutes) firms the chicken and makes slicing cleaner.
- Marinate Ahead, but Not Forever. One hour is plenty for tender strips; four hours deepens flavor. Overnight is okay, but more than 12 hours can turn the texture mushy because lime juice is acidic. Keep the bag flat in the fridge so every piece sits in liquid.
- Heat Matters. Use medium-high heat for peppers so they blister without steaming. After removing the vegetables, let the pan re-heat for 30 seconds before adding chicken. The sizzle you hear is moisture evaporating and spices roasting—keys to fajita char.
- Warm Tortillas Right Before Serving. A quick turn in a dry skillet (15–20 seconds each side) makes tortillas soft and pliable. Stack them in a towel-lined bowl to keep them steamy until everyone is ready to fill.

Chicken Fajita Tacos with Peppers and Onions
Ingredients
Method
- Marinate the ChickenIn a large resealable bag, combine olive oil, lime juice, salt, pepper, oregano, cumin, garlic powder, chili powder, smoked paprika, onion powder, and red pepper flakes. Add chicken strips, press out air, seal, and massage to coat. Refrigerate at least 1 hour (up to 4; see tip).
- Cook the VegetablesHeat 1 Tbsp olive oil in a large skillet over medium-high. Add bell peppers and red onion wedges. Cook, stirring every minute, until edges char and centers soften, about 5–6 minutes. Add green onions for the last 60 seconds. Transfer vegetables to a plate and tent with foil.
- Sear the ChickenReturn the skillet to medium-high and pour in remaining 1 Tbsp oil. Using tongs, add marinated chicken in a single layer. Discard excess marinade. Cook 5 minutes undisturbed to brown, then flip and cook 3–4 minutes more, turning occasionally, until no pink remains and internal temperature reaches 165 °F.
- Finish Fajita MixReturn peppers and onions to the skillet. Toss with chicken for 1 minute so flavors mingle and everything is piping hot. Taste and add salt if needed.
- Warm TortillasWhile the filling finishes, heat a dry skillet over medium. Warm each tortilla 15–20 seconds per side until flexible and lightly spotted. Stack in a clean towel to keep warm.
- Assemble TacosSpoon chicken-pepper filling down the center of each tortilla. Top with cheese, salsa, guacamole, taco sauce, and sour cream as desired. Fold and serve hot.
