When you want maximum Tex-Mex flavor with minimal cleanup, Sheet Pan Chicken Fajitas with Lime Crema is the ultimate solution. Juicy chicken breast strips, sweet bell peppers, and sliced red onions are tossed in a smoky homemade spice blend, roasted at high heat until caramelized, and drizzled with a velvety, zesty lime crema.
The secret to juicy sheet pan chicken that doesn’t dry out while waiting for the peppers to soften is Roasting at High Heat (425°F / 220°C) on a Preheated Sheet Pan without Overcrowding. Searing the meat and vegetables on a hot pan browns the edges quickly, trapping the chicken juices while keeping the peppers tender-crisp.

Key Ingredients Overview
- Chicken Breast or Thighs: 1½ lbs boneless, skinless chicken sliced into uniform ½-inch strips.
- Bell Peppers & Onions: 3 colorful bell peppers (red, yellow, green) and 1 large red onion, sliced lengthwise.
- Smoky Fajita Spice Mix: Chili powder, ground cumin, smoked paprika, garlic powder, onion powder, dried oregano, salt, and black pepper.
- Lime Crema: Sour cream (or plain Greek yogurt), fresh lime zest, lime juice, garlic powder, and a pinch of salt.
- Warm Tortillas: Small flour or corn tortillas for serving.
Step-by-Step Instructions
1.Whisk the Zesty Lime Crema:3 min.
In a small bowl, whisk together ½ cup sour cream (or plain Greek yogurt), 1 tablespoon fresh lime juice, 1 teaspoon lime zest, ¼ teaspoon garlic powder, and a pinch of salt until smooth and pourable. Cover and chill in the fridge until ready to serve.
2.Slice & Season Chicken and Veggies:5 min.
Preheat your oven to 425°F (220°C). Slice 1½ lbs chicken breasts, 3 bell peppers, and 1 red onion into ½-inch wide strips. In a large bowl (or directly on a large rimmed sheet pan), toss everything with 3 tablespoons olive oil, 1½ teaspoons chili powder, 1 teaspoon cumin, 1 teaspoon smoked paprika, ½ teaspoon garlic powder, ½ teaspoon onion powder, 1 teaspoon salt, and ½ teaspoon black pepper.
3.Roast at High Heat:20 min.
Spread the chicken and vegetables in a single, even layer across the baking sheet (ensure the pan isn’t overcrowded so ingredients roast instead of steam). Bake for 18 to 22 minutes, tossing halfway through, until the chicken is cooked through (165°F / 74°C internal temperature) and the pepper edges are charred and caramelized.
4.Warm the Tortillas:5 min.
During the last 5 minutes of roasting, wrap a stack of flour or corn tortillas in aluminum foil and place them on the bottom oven rack to warm through.
5.Assemble & Serve Hot:2 min.
Remove the sheet pan from the oven. Squeeze fresh lime juice over the hot chicken and peppers. Drizzle generously with the chilled lime crema, garnish with fresh chopped cilantro, and serve immediately with warm tortillas!

Expert Tips for Success
- Don’t Overcrowd the Sheet Pan: Trapped steam prevents caramelization! If your baking sheet is small, split the chicken and veggies between two separate sheet pans for maximum charred edges.
- Cut Strips Uniformly: Slice chicken and peppers into equal ½-inch thicknesses so everything cooks through at the exact same time without drying out the meat.
- Greek Yogurt Swap: For a lighter, higher-protein crema, swap sour cream for plain whole-milk Greek yogurt—it offers the same rich tang with fewer calories.
