Ingredients

Gather the following ingredients to whip up your Sheet Pan Chicken Fajitas:

• Chicken – You can opt for chicken breasts or boneless thighs. Thighs tend to stay juicier, while breasts cook faster.
• Mini Sweet Peppers – I prefer these for their sweetness and juiciness. Regular bell peppers work just as well!
• Red Onions – Milder and more colorful than white onions, making them a great choice for these fajitas.
• Garlic – Fresh minced garlic adds a wonderful depth of flavor!
• Fajita Seasoning – You can make your own blend using chili powder, smoked paprika, cumin, onion powder, salt, and pepper, or use a store-bought mix.
• Olive Oil – This will help your fajitas brown nicely in the oven.
• Lime Juice – Perfect for marinating and serving, lime juice brightens the dish wonderfully.
• Tortillas – Flour tortillas (6 or 7-inch) are ideal for serving; don’t forget to warm them up!
• Optional toppings – Sour cream, guacamole, cheese, or salsa can enhance your fajitas.

How to Make Sheet Pan Chicken Fajitas

This sheet pan version of chicken fajitas is a lifesaver on busy days when time is short but taste is a priority. Plus, it’s very adaptable; you can leave out ingredients you don’t like or mix in your favorites!

Step 1: Prep the Chicken and Veggies

• Cut the chicken against the grain into chunky strips to keep them juicy.
• Halve, core, and deseed the sweet peppers.
• For the onions, cut them into petals for a lovely presentation and even cooking.

Step 2: Marinate

• In a large bowl, combine chicken, peppers, onion, olive oil, lime juice, and seasoning. Toss well and let it marinate for at least 15 minutes (or even overnight) in the fridge for maximum flavor.

Step 3: Roast in the Oven

• Spread the mixture on a large, greased baking sheet.
• Roast in the preheated oven at 375ºF for about 20 minutes, tossing halfway to ensure even cooking.
• For that charred flavor, broil for an additional 3-5 minutes, rotating often.
• Serve immediately with warm tortillas and toppings of your choice!

Serving Suggestions

Pair your fajitas with delicious toppings like sour cream, guacamole, sliced jalapeños, shredded cheese, fresh cilantro, and of course, some fragrant lime wedges. A side of yellow rice and seasoned black beans rounds out this wonderful meal perfectly!

Fajitas Variations

Feel free to switch things up with your fajitas! Here are some ideas you might enjoy:

• Substitute chicken with steak, pork, shrimp, or even fish—just adjust the cooking time.
• Mix in additional veggies like zucchini, mushrooms, or cauliflower.
• Add a bit of heat with cayenne pepper or your favorite hot sauce in the marinade.
• Transform the fajitas into bowls by serving over rice.
• For a low-carb option, enjoy on lettuce wraps or low-carb tortillas.

Storing and Reheating Chicken Fajitas

Fridge: Allow cooked fajitas to cool, then store in an airtight container for up to 4 days.

Freezer: Uncooked fajitas can be frozen (in marinade) for up to 2 months. Avoid freezing cooked fajitas; they can become soggy.

Reheat: Warm the cooked fajitas in a skillet over medium-low heat or microwave in 30-60 second increments.
