Ingredients You’ll Need
These sheet pan fajitas are made with simple ingredients and a quick homemade seasoning.
- Chicken Breasts – sliced into thick strips so they stay juicy as they roast.
- Bell Peppers – use a mix of colors for the prettiest pan.
- Red Onion and Garlic – roast until sweet and tender.
- Olive Oil – helps everything roast evenly.
- Fajita Seasoning – chili powder, cumin, paprika, coriander, onion powder, salt, and pepper.
- For Serving – flour tortillas, lime wedges, fresh cilantro, and sliced avocado.
Step-by-Step Instructions
First, prep the pan. Preheat the oven to 425°F. Line a large baking sheet with parchment paper.
Next, assemble. Spread the chicken, bell peppers, onions, garlic, and olive oil on the baking sheet. Mix the seasoning ingredients and sprinkle evenly over everything.
Now toss and bake. Toss to coat, spread into a single layer, and bake for 15-20 minutes, stirring once halfway through, until the chicken is cooked and the vegetables are tender.
Warm the tortillas. In the last 5 minutes, wrap a stack of tortillas in foil and place them on the baking sheet.
Finally, serve. Serve with warm tortillas, lime wedges, cilantro, and avocado.
That’s it! Fajita night made easy.
Expert Tips
Cut everything evenly. Similar-sized strips cook at the same rate.
Use a big pan. A single layer helps everything roast instead of steam.
Broil for a char. A minute or two under the broiler adds those classic fajita edges.
Finish with lime. A squeeze of fresh lime right before serving brightens everything up.
Storage & Reheating Tips
- Best Enjoyed Fresh: Fajitas are best served immediately.
- Short-Term Storage: Wrap leftovers in foil or store in an airtight container in the fridge for up to 2 days.
- Reheating: Warm in a pan over medium heat or microwave until heated through.
Recipe Variations
I love these fajitas as they are, but it’s easy to make your own.
Use different colored peppers and onions, or add sliced zucchini or mushrooms.
Swap the chicken for shrimp or steak, adjusting the bake time as needed.
Serve over rice or lettuce for a low-carb fajita bowl.
Serving Suggestions
Top your fajitas with sour cream, salsa, shredded cheese, or homemade guacamole.
Serve with Mexican rice, refried beans, or fried corn on the side.
Recipe FAQs
1. Can I use chicken thighs?
Yes. Boneless, skinless thighs stay juicy and work great.
2. Can I use store-bought fajita seasoning?
Absolutely. Use about 2 tablespoons in place of the homemade blend.
3. How do I know the chicken is done?
It should reach 165°F inside and no longer be pink.
4. Can I make these ahead?
They’re best fresh, but leftovers keep for up to 2 days in the fridge.
5. Are they spicy?
They’re mildly spiced. Add cayenne or jalapeños for more heat.
