Sheet Pan Chicken Fajita with Sour Cream Lime Sauce
Sheet Pan Chicken Fajita Recipe
This sheet pan chicken fajita is an easy, flavorful weeknight dinner that bakes all on one tray. With simple prep, minimal cleanup and a total cook time under 30 minutes, it’s perfect for busy cooks who want bold fajita flavors without fuss. The chicken is marinated with warm spices, roasted with bell peppers and onions, and served with a tangy sour cream-lime sauce. Serve in warm tortillas or over rice for a quick family meal.
The recipe uses pantry-friendly spices—cumin and chili powder—for an authentic fajita taste. The sour cream-lime sauce brightens the dish and pairs perfectly with the roasted vegetables and juicy chicken. This method is flexible: use chicken breasts as written or swap for thighs or thinly sliced beef if you prefer.

Chicken Fajita Ingredients
These ingredients are typical pantry staples and produce you can easily find at most grocery stores:
- Cumin – adds warm, earthy flavor to the fajita seasoning.
- Chili powder – gives mild heat and depth; it also complements the lime in the sauce.
- Chicken breast – sliced into strips; bakes quickly and stays juicy when marinated.
- Ground black pepper – for balanced spice without overpowering the dish.
- Lime wedges – essential for finishing the fajitas with fresh acidity.
- Bell peppers – colorful and sweet when roasted; use as many as you like.
- Tortillas – warm flour or corn tortillas for serving.
- Sour cream – forms the base of the lime sauce and softens the spice.
- Cilantro – fresh herb garnish that brightens each bite.
Main Ingredients
- 2 lbs chicken breast, cut into strips
- 3 small bell peppers, sliced
- 1 cup red or yellow onion, sliced
Marinade
- 2 tablespoons olive oil (or any neutral oil)
- 1/2 teaspoon salt
- 1 teaspoon ground cumin
- 1/2 teaspoon chili powder
- 1/2 teaspoon ground black pepper
Sauce
- 1/2 cup light sour cream
- 1 tablespoon lime juice
- 1/2 teaspoon granulated sugar
- 1/4 teaspoon chili powder
- 1/4 teaspoon ground black pepper
Garnish
- Fresh cilantro
- Additional lime wedges or a splash of lime juice
Instructions
- Prepare the marinade: whisk together the olive oil, salt, ground cumin, chili powder and black pepper in a bowl.
- Divide the marinade in half. Toss the chicken strips in one half so they are evenly coated. For best flavor, marinate the chicken for at least 4 hours or overnight in the refrigerator.
- Place the sliced bell peppers and onions in a separate bowl and toss them with the remaining half of the marinade.
- Preheat the oven to 400°F (200°C). Arrange the marinated vegetables on a sheet pan and place the chicken strips in the center or in a single layer across the pan.
- Bake in the preheated oven for about 26 minutes, or until the chicken is cooked through and the vegetables are tender and slightly charred at the edges.
- While the fajitas bake, make the sauce: combine the light sour cream, lime juice, granulated sugar, chili powder and ground pepper in a small bowl. Stir until smooth and chill until ready to serve.
- When the chicken is done, remove the sheet pan from the oven. Squeeze fresh lime over the chicken and vegetables, and scatter chopped cilantro on top.
- Serve the chicken and vegetables in warmed tortillas or over rice. Drizzle with the sour cream-lime sauce and add extra lime wedges on the side.
Tips & Variations
- Swap chicken breast for thighs or thinly sliced flank steak for a different texture and flavor.
- If you prefer more char, broil for 1–2 minutes at the end of baking—watch closely to avoid burning.
- Make it low-carb by serving over lettuce or cauliflower rice instead of tortillas.
- Adjust the chili powder to taste for milder or spicier fajitas.
- Double the sauce if you like extra creaminess for dipping or drizzling.
