Flour tortillas and fajita seasoning mix on a table.

How to Make Sheet Pan Fajitas

Step #1: Preheat your oven to 425°F (218°C). Divide the chicken, bell peppers, and onions evenly between two rimmed half-sheet pans.

Step #2: In a small bowl, whisk together the fajita seasoning and vegetable oil. Drizzle half of the mixture over each baking sheet. Toss the chicken and vegetables until they are well coated in the seasoning.

Step #3: Place both sheet pans in the preheated oven and bake for 10 minutes.

Step #4: Turn on the oven’s broiler. Char the fajitas to your liking by broiling, checking, and stirring every 60-90 seconds, which should take about 3-5 minutes in total.

Step #5: Serve in a warm flour tortilla or in a lettuce wrap and with your choice of toppings.

Expert Tips

  • Line with Parchment Paper: Lie your sheet pan with parchment paper before arranging the chicken and vegetables. It prevents sticking, and makes cleanup even easier. Just be sure to leave some space around the edges for proper heat circulation.
  • Pat Dry to Enhance Spice Adhesion: Before adding seasoning, pat the chicken and vegetables dry with paper towels. This removes excess moisture and helps the spices stick to your ingredients.
  • Warm Tortillas for Better Texture: Lightly fry the tortillas in a pan or dry skillet using a bit of olive oil. You can also directly heat them over a gas flame just until they’re warm and pliable. This will greatly improve their texture and flavor.
  • Fajita Marinade: Marinate the chicken in a mixture of fajita seasoning, fresh lime juice, and oil for at least 30 minutes prior to cooking to deepen the flavor.
  • Finishing with a Broil: For the last few minutes of cooking, switch to the broiler setting to char the chicken and vegetables lightly, adding a smoky depth.

Frequently Asked Questions

What’s the best way to keep vegetables crisp in Sheet Pan Fajitas?

Roast at a high temperature, around 425°F (218°C), and ensure vegetables are not overlapping on the pan. This promotes caramelization and prevents them from steaming and becoming soggy.

How can I accurately ensure the chicken in my Sheet Pan Fajitas is fully cooked?

Use a meat thermometer to check the internal temperature of the chicken. It’s safe to eat when the temperature reaches 165°F (74°C). This avoids undercooking or drying out the meat.

What are some creative and tasty toppings for Sheet Pan Fajitas?

Classic toppings like sour cream, guacamole, and salsa are great. You can also try pickled red onions, grated cheese, or a squeeze of fresh lime juice for added zest.

Can I incorporate beans into the Sheet Pan Fajitas for more texture and protein?

Yes, adding cooked black beans or pinto beans during the last few minutes of cooking adds protein and texture. Ensure they’re warmed through before serving.

What’s a simple way to increase the spice level in Sheet Pan Fajitas?

For more heat, add sliced jalapeños or a few dashes of hot sauce. You can also sprinkle extra chili powder, paprika, or cayenne pepper into the seasoning mix.

Storage Info

You can store Sheet Pan Fajitas in an airtight container in the refrigerator for up to 3-4 days. For freezing, just place the cooled fajitas in a freezer-safe container or bag, where they’ll stay good for up to 2 months. To reheat, thaw in the refrigerator if frozen, then warm in a skillet over medium heat or in the microwave, stirring occasionally, until heated through.

  1. Made this tonight for a crew of college boys. They loved it because it was tasty, and I loved it because it was easy! I cut up the chicken last night, tossed half the seasoning and a little olive oil into a ziplock bag with it, and let it sit until just before cooking. Chopped up the veggies ahead and stored them in another ziplock bag until cooking. Worked beautifully and made for no prep except for making the guacamole! Perfect for a crowd!

      1. Yes, you can use one full sheet pan (18 inches by 26 inches) instead of two half sheet pans (18 inches by 13 inches).

    1. Hi, Crystal! I’m so sorry, I’m not sure how I missed putting in the serving information into the recipe card. This recipe makes two full half-pans of fajita filling, so it should serve between 10-12 people.
