How to Make Sheet Pan Chicken Fajitas

Step-by-Step Cooking Instructions

Step 1: Heat the oven to 425°F (220°C). Line a large rimmed sheet pan with foil or parchment for easy cleanup.

Step 2: Slice the chicken, peppers, and onion into thin strips. Pat the chicken dry with paper towels.

Step 3: In a large bowl, mix olive oil, lime juice, and the fajita seasoning (or spice blend). Add the chicken and toss to coat well.

Step 4: Add the sliced peppers and onion to the bowl. Toss until everything is evenly coated with oil and spices.

Step 5: Spread the chicken and vegetables in a single layer on the sheet pan. Do not crowd; use two pans if needed.

Step 6: Roast for 18–22 minutes at 425°F (220°C), until the chicken is cooked through (165°F/74°C). For a light char, broil for 2–3 minutes at the end.

Step 7: Squeeze extra lime over the pan, sprinkle with cilantro, and serve hot with warm tortillas and your favorite toppings.

Tips for Texture, Timing & Tools

• Use a hot oven (425°F) for tender chicken and crisp edges.
• Cut chicken and veggies into even strips so they cook at the same rate.
• Do not crowd the pan. Overcrowding steams the food and softens the peppers.
• Preheat the sheet pan for extra char on the veggies.
• Warm tortillas in foil in the oven for the last 5 minutes, or toast them in a dry skillet.

Storage & Reheating

How to Store It Right

• Cool leftovers, then store chicken and veggies in an airtight container for up to 4 days.
• Keep tortillas and toppings separate for the best texture.
• For freezing, store the cooked chicken and veggies in freezer bags for up to 2 months. Thaw in the fridge overnight.

Reheating Without Losing Flavor

• Skillet: Reheat over medium heat with a splash of water or lime juice for 3–4 minutes.
• Oven: Spread on a sheet pan, cover loosely with foil, and warm at 350°F (175°C) for 8–10 minutes.
• Microwave: Reheat in short bursts and stir once to keep from drying out. Add a squeeze of lime after.

FAQs

Can I use chicken thighs instead of breasts?

Yes. Use boneless, skinless thighs, sliced thin. They stay very juicy. Roast for about the same time and check for 165°F (74°C).

What size sheet pan should I use?

A standard half-sheet pan (18×13 inches) works well. If the pan looks crowded, split the mix across two pans.

How do I make these fajitas less spicy?

Skip the cayenne and use mild chili powder. You can also add more lime and a little honey to balance heat.

Can I prep this ahead?

Yes. Slice chicken and veggies and toss with the spice mix up to 24 hours ahead. Store covered in the fridge. Cook when ready.
