• Ingredient	Quantity	Notes

  Bell peppers (red, yellow, orange)	3 large	Sliced thin
  Yellow onion	1 medium	Sliced thin
  Olive oil	2 Tbsp	For roasting chicken and vegetables
  Fresh lime juice	1 lime (about 2 Tbsp)	Essential final touch, for serving
  Chili powder	2 tsp	Homemade Fajita Seasoning: Whisk these spices together
  Cumin	1 tsp
  Onion powder	1 tsp
  Garlic powder	1 tsp
  Kosher salt	1/2 tsp	To taste; adjust as needed
  Red pepper flakes	Pinch	Optional, for a kick

The Countdown: How to Make It in 5 Simple Steps

Follow these steps for guaranteed success and a perfect char.

1. Preheat & Prep: Preheat your oven to 425°F (220°c). This high heat is crucial for achieving that beautiful roast and char on your ingredients.
2. Make the Seasoning: In a small bowl, quickly whisk together your homemade fajita seasoning: chili powder, cumin, onion powder, garlic powder, salt, and a pinch of red pepper flakes.
3. Toss Everything: Directly on your large sheet pan, combine the chicken strips, sliced bell peppers, and yellow onion. Drizzle with olive oil and sprinkle the seasoning mix generously over everything. Toss with tongs until every piece is evenly coated.
4. Spread & Roast: Arrange everything in a true single layer on the baking sheet. If the pan is crowded, use two! Roast for 15-20 minutes, or until the chicken is fully cooked (165°F/74°c}) and the veggies have tender, slightly charred edges.
5. The Final Sizzle: Squeeze the fresh lime juice over the entire pan straight from the oven. This bright acidity “wakes up” all the savory flavors.

Chef’s Secrets: Pro-Tips for Sizzle & Char

Want to take your fajitas from great to legendary? These simple tricks make all the difference.

• The Sizzling Platter Trick: For that authentic “sizzling platter” effect, warm your serving platter in the oven for the last 5 minutes of cooking. When you transfer the hot chicken and veggies from the baking sheet, they’ll hit the warm platter with an impressive hiss that keeps them hotter for longer.
• Char Your Tortillas: Don’t just warm your flour tortillas—lightly char them! Place them directly over a gas burner flame for a few seconds per side (using tongs!) or sear them in a dry skillet. This adds a subtle, irresistible smokiness that complements the seasoning perfectly.
• Customize Your Creations: Set out a spread of fajita toppings in small bowls and let everyone build their own perfect wrap.

Build Your Perfect Bite: Toppings Spread

• The Base: Warm flour or corn tortillas.
• The Creamy Element: Sour cream, Greek yogurt, or Mexican crema.
• The Fresh Additions: Diced avocado or guacamole, pico de gallo, or fresh cilantro.
• The Extra Zing: More fresh lime juice or your favorite hot sauce.

FAQs: Your Quick-Fire Fajita Questions, Answered

Can I use chicken thighs instead? Absolutely! Boneless, skinless chicken thighs will work wonderfully and stay incredibly juicy. Just note that the cooking time may be slightly longer, so check for doneness around the 20-minute mark.

My veggies are getting soggy. What happened? Crowding the pan is the usual culprit. For the best roast and char, you must use a truly large sheet pan and ensure the chicken and veggies are spread in a single layer. If they overlap, they steam instead of roast. Use two pans if necessary!

What other seasonings can I add? A teaspoon of smoked paprika would add a lovely, smoky depth to the homemade fajita seasoning. Alternatively, a pinch of cayenne pepper will give it extra heat.

The Final Takeaway

See? Incredible, restaurant-quality chicken fajitas don’t require any special equipment or chef-level skills. With one pan and a handful of simple ingredients, you can create a meal that’s as fun to eat as it is delicious.
