Sheet-Pan Chicken Fajitas with Lime Crema

This sheet-pan chicken fajita dinner brings together juicy roasted chicken, sweet bell peppers, and red onion on a single baking sheet.

A sprinkle of fajita seasoning, a blanket of melted cheese, and a cool lime crema finish make every bite golden and mouthwatering. It's the kind of meal that looks and tastes like you spent hours, but it comes together in about half an hour.

Sheet-pan dinners are the ultimate weeknight shortcut, and these chicken fajitas are no exception. Everything roasts together on one pan, so the chicken stays tender while the peppers and onions caramelize at the edges.

A final broil with cheese and a drizzle of lime crema turns the whole tray into a sizzling, flavor-packed centerpiece. Serve with warm tortillas and let everyone build their own fajitas at the table.

Ingredients

Why this recipe works

Roasting the chicken and vegetables on a single sheet pan allows the high oven heat to caramelize the natural sugars in the peppers and onions, creating deep, sweet flavor.

The chicken breast strips cook quickly and stay juicy because they're cut thin and roasted at 425°F (220°C), not sautéed in a crowded skillet. The direct heat also gives the edges a light char that mimics the flavor of a grill.

The fajita seasoning is applied directly to the chicken and vegetables before roasting, so every bite is evenly seasoned. Broiling the cheese at the end creates a bubbly, golden crust that contrasts with the tender chicken.

The lime crema adds a cool, tangy finish that balances the smoky spices, and the cilantro brings a fresh, herbal note that brightens the whole dish.

Notes and substitutions

Use a good-quality fajita seasoning or make your own with chili powder, smoked paprika, cumin, garlic powder, onion powder, and salt. If using a store-bought blend, check the label for added salt and adjust the amount to taste. Slicing the chicken breast into even strips ensures it cooks at the same rate as the peppers and onions.

A large rimmed baking sheet is essential to keep everything in a single layer, which promotes even browning. If the pan is crowded, the vegetables will steam instead of roast. For a spicier version, add sliced jalapeños or use a hot chili powder in the seasoning. You can also swap the chicken for thinly sliced steak, but adjust the cooking time accordingly.
