The Crispiest, Easiest Chicken Fajitas You’ll Ever Make

Let’s be honest: the best part of any roasted chicken is that shatteringly crispy, golden-brown skin. I’ve been a fan since I was a kid, sneaking the best bits off the Thanksgiving turkey before my mom could even carve it! That’s why I’m swapping the usual boneless chicken for rich, skin-on thighs in this fajita recipe. We pan-sear them to crispy perfection before roasting them on a single sheet pan with a rainbow of peppers and onions. The result is an incredibly flavorful, easy-to-make meal that will change how you think about fajitas forever. For a creamy, spicy finish, don’t forget a drizzle of Lime Sriracha Aioli!

Ingredients

• 1 medium red bell pepper, about 6 oz / 170g, seeded and sliced
• 1 medium yellow bell pepper, about 6 oz / 170g, seeded and sliced
• 1 medium green bell pepper, about 6 oz / 170g, seeded and sliced
• 1 small onion, about 5 oz / 140g, sliced
• 4 cloves garlic, minced
• 3 tablespoons avocado oil or olive oil, divided
• 1 tablespoon fresh lime juice
• 3 tablespoons Fajita Seasoning, divided
• 8 bone-in, skin-on chicken thighs, about 2 lbs / 900g
• 1 lime, cut into wedges, for serving
• Handful of torn fresh cilantro, or 2 green onions, sliced, for garnish

Instructions

1. Directions1. Preheat oven to 400°F / 200°C. In a large bowl, toss the bell peppers, onion, garlic, 2 tablespoons of oil, lime juice, and 2 tablespoons of fajita seasoning. Spread the coated vegetables in a single layer on a large, rimmed baking sheet.2. Heat the remaining 1 tablespoon of oil in a large cast-iron skillet over medium-high heat. While the pan heats, pat the chicken thighs completely dry with a paper towel and season on all sides with the remaining 1 tablespoon of fajita seasoning.3. Place the chicken in the hot skillet skin-side down and sear until crispy and golden brown, about 3-4 minutes per side. Note: The chicken will not be fully cooked at this stage.4. Arrange the seared chicken thighs on top of the vegetables on the sheet pan. Bake for 15-20 minutes, or until the chicken is cooked through (reaching an internal temperature of 165°F / 74°C) and the vegetables are tender. Serve immediately with lime wedges and a garnish of cilantro or sliced green onions, if desired.

Pro Tips

• For the absolute crispiest skin, pat the chicken thighs completely dry with a paper towel before you season and sear them. Moisture is the enemy of crispiness!
• Don’t overcrowd the sheet pan. If your pan is too full, the vegetables will steam instead of roast. Use two pans if necessary for the best results.
• This recipe is versatile! You can use boneless chicken thighs or breasts. Simply cube the raw chicken, toss it with the seasoning, and add it directly to the sheet pan with the vegetables, adjusting the bake time as needed.

FAQ

Q: How do you get the chicken skin so crispy
A: For the crispiest skin, first pat the chicken thighs completely dry with a paper towel. Then, sear them skin-side down in a hot skillet for 3-4 minutes until golden brown before baking.

Q: Can I use boneless chicken for this recipe
A: Yes, you can use boneless chicken thighs or breasts. The recipe notes suggest cubing the raw chicken, tossing it with seasoning, and adding it directly to the sheet pan with the vegetables, adjusting the bake time as needed.

Q: What internal temperature should the chicken reach
A: The chicken is fully cooked and safe to eat when it reaches an internal temperature of 165°F (74°C). Use a meat thermometer for the most accurate result.
