🍚 Rice and Grains

A warm, seasoned rice dish makes the perfect side to soak up all that fajita goodness.

• Cilantro Lime Rice – zesty and fresh, just like your favorite takeout spot

• Mexican Rice – tomatoey, savory, and studded with veggies

• Cauliflower Rice – for a lighter, low-carb option

• Quinoa – adds extra protein and a slightly nutty flavor

Pro tip: Use leftovers to build fajita bowls the next day!

🫘 Beans and Legumes

No Tex-Mex meal feels complete without some beans on the side:

• Refried Beans – creamy and classic

• Black Beans – seasoned with garlic, cumin, and lime

Tips for the Best Sheet Pan Chicken Fajitas

• 🔪 1. Slice Everything Evenly

  Uniform slices = even cooking.

  • Chicken: Cut into thin, even strips so it cooks quickly and doesn’t dry out.

  • Peppers and onions: Go for ¼-inch strips so they roast beautifully without getting mushy or burning.

  🔥 2. Use a Hot Oven

  Roast at 425°F (220°C) to get that nice charred edge — the kind that makes fajitas taste like they just came off a cast iron skillet. This high heat caramelizes the veggies and seals in moisture in the chicken.

  🌶️ 3. Don’t Overcrowd the Pan

  Spread your chicken and veggies out in a single layer with space between them. If the pan is too crowded, they’ll steam instead of roast. Use two sheet pans if needed!

  🧂 4. Season Generously

  The key to bold fajita flavor is the seasoning mix. Make your own with:

  • Chili powder, paprika, cumin, garlic powder, onion powder, salt, pepper, and a squeeze of lime juice.
    If using store-bought seasoning, check for added salt so your fajitas don’t turn out too salty.

  🍋 5. Add Lime Juice Before Serving

  A squeeze of fresh lime juice right out of the oven makes everything pop! It brightens the flavors and gives that signature fajita zing.

  🫓 6. Warm the Tortillas

  Don’t forget the tortillas!

  • Wrap them in foil and warm in the oven for the last 5 minutes of roasting, or

  • Quickly toast them in a dry skillet for soft, pliable wraps that won’t crack.

  🥑 7. Add a Creamy or Crunchy Topping

  Balance all that bold roasted flavor with creamy or fresh toppings:

  • Creamy: Avocado, sour cream, or Greek yogurt

  • Crunchy: Shredded lettuce, radishes, or pickled onions

  • Fresh: Chopped cilantro, diced tomatoes, salsa fresca

  🥣 8. Meal Prep Like a Pro

  • Slice and season everything in advance — store in the fridge up to 24 hours before baking.

  • Double the batch and use leftovers in rice bowls, salads, or quesadillas later in the week.

Storage Instructions

Refrigerator:

• Store cooked fajita mixture in an airtight container for up to 4 days.

• Keep toppings and tortillas separate for best freshness.

Reheat:

• Reheat in a skillet over medium heat or in the microwave until warmed through.

Freezer:

• You can freeze the uncooked seasoned chicken and veggies in a zip-top bag. Thaw overnight and roast when ready!

Meal prep tip: Divide into containers with rice or tortillas on the side for grab-and-go lunches.

Frequently Asked Questions

Can I make this ahead of time?

Yes! You can slice and season everything ahead of time and store it in the fridge for up to 24 hours. Then just toss it on the pan and roast when you’re ready.

Both chicken breasts and thighs work well — thighs are juicier, breasts are leaner. Just slice them thinly for quick, even cooking.

Can I make this spicy?

Absolutely! Add a pinch of cayenne or some sliced jalapeños to the sheet pan before roasting.

Is this recipe gluten-free?

Yes — just use gluten-free corn tortillas and make sure your seasonings don’t contain hidden gluten.
