Traditionally, fajitas are made in a sizzling hot cast iron griddle, but busy weeknights call for quick cooking, easy-to-clean-up meals. That’s why sheet pan recipes are brilliant. It’s an easy, efficient way to prepare everything you need for a meal on one pan and it's especially perfect for making fajitas.

Taco seasoning is a powerhouse, transforming humble ingredients like bell peppers, onions, and chicken breasts into a satisfying, flavorful filling to wrap in warm tortillas. Store-bought taco seasoning is easy and convenient or make your own for a fun weekend pantry project.

Choose a colorful mix of peppers for some flair and added flavor. The peppers and onions need a head start to ensure they’re tender enough, so get them roasting in the oven while you slice the chicken into strips. Halfway through, the chicken gets added to the pan (you could swap in beef or pork here, or use all veggies for a vegetarian spin).

For these sheet pan chicken fajitas, the only extra prep is heating tortillas on the stovetop, an easy task while your oven does the heavy lifting (and something kids can help do, too!).

A quick homemade crema—sour cream thinned with a bit of water (or lime juice) for a citrusy twist, and seasoned with salt—adds a refreshing finishing touch to drizzle on top before you dive in to dinner.

Ingredients

  • 2 tablespoons olive oil
  • 2 bell peppers
  • 1 medium yellow onion

  • 1 lime
  • 1/4 cup sour cream
  • Salt and pepper
  • Optional: 1 1/2 cups hot cooked rice

Tips

  • For a faster way to heat the tortillas, wrap them in foil and place them in the oven during the last 5 to 7 minutes of cooking the peppers, onions, and chicken. They’ll heat up nicely and the ease of prep is enough to forgive the lack of char you’d get from heating them in a skillet.
  • Cooked rice isn’t a necessity, but it bulks up the meal. You could even opt for a fajita bowl and serve the tortillas on the side.
