Easy Sheet Pan Chicken Fajitas with Citrus Marinade + Charred Jalapeño Crema

When weeknights get busy, sheet pan chicken fajitas are a lifesaver. This version combines a bright citrus marinade with roasted poblanos and bell peppers, finished with a smoky, dairy-free charred jalapeño crema. It’s simple to prepare, bakes all on one sheet pan, and delivers a balanced, protein-packed meal that’s easy to customize to different dietary needs.

Whole Ingredients, Bold Flavor

The heart of this dish is the citrus-marinated chicken. Orange zest and juice brighten the flavor while smoked paprika, cumin, and coriander add warmth and depth. These simple pantry spices pair beautifully with roasted peppers and onions to create a meal that’s satisfying and full of color.

The charred jalapeño crema is creamy and cooling, made here with dairy-free yogurt for a probiotic boost, though regular sour cream or Greek yogurt works just as well if dairy isn’t a concern. Charred jalapeños bring a subtle smokiness and a controllable heat that complements the citrusy chicken.

Easy Sheet Pan Chicken Fajitas with a Zesty Citrus Twist

Oven-baked fajitas are incredibly versatile. Serve the roasted chicken and peppers in warm corn tortillas, crisp lettuce cups, or over a bed of greens for a lighter, low-carb option. I like to finish mine with avocado slices, extra cilantro, and a squeeze of the roasted lime for a bright finish.

This one-pan dinner is perfect for family meals or for prepping a few portions to enjoy during the week. Leftovers reheat nicely in a skillet or the oven without losing their flavor.

Charred Jalapeño Crema:

• 1 large jalapeño, halved and seeds removed
• ⅓ cup dairy-free yogurt or sour cream

HOW TO MAKE SHEET PAN CHICKEN FAJITAS WITH CITRUS MARINADE + CHARRED JALAPEÑO CREMA (GLUTEN & DAIRY-FREE)

1. Preheat the oven to 425°F (220°C).
2. Line a large sheet pan with parchment for easy cleanup. Arrange the chicken, bell pepper, poblano, and red onion in sections in an even layer on the pan.
3. In a small bowl, whisk together avocado oil, orange zest and juice, smoked paprika, cumin, garlic powder, oregano, coriander (if using), and sea salt. Pour this marinade over the chicken and vegetables, then toss with your hands or tongs until everything is evenly coated. Nestle the lime halves cut-side up on the pan to roast alongside.
4. Roast for 18–20 minutes, flipping everything once halfway through, until the chicken is cooked and the vegetables are tender with caramelized edges. For extra char, broil for the final 1–2 minutes—watch closely so nothing burns.
5. While the sheet pan roasts, heat a dry skillet over medium-high heat. Place the jalapeño halves cut-side down and sear for 3–4 minutes until the skin blisters and blackens in spots. Transfer the jalapeño to a blender with the dairy-free yogurt (or sour cream), lime juice, salt, cilantro, and garlic if using. Blend until smooth and creamy. Taste and adjust seasoning as needed.
6. To serve, layer the roasted chicken and veggies into warm tortillas or lettuce cups. Add avocado slices, a generous drizzle of the jalapeño crema, and finish with a squeeze of the charred lime.

RECIPE SUBSTITUTIONS & TIPS

This recipe is easy to adapt based on preferences or what you have on hand:

• Swap thin-sliced chicken breasts for boneless chicken thighs if you prefer a juicier result.
• Use shrimp for a lighter, quicker-cooking option—reduce roasting time accordingly.
• If you don’t have poblanos, sliced zucchini, mushrooms, or additional bell peppers all work great roasted alongside the chicken.
• For the crema, Greek yogurt or sour cream are excellent substitutes if you aren’t avoiding dairy.
• Adjust the heat by using more or fewer jalapeños, or substitute a milder pepper such as Anaheim if you want less spice.
• Serve in gluten-free corn tortillas, lettuce cups, or over greens to fit gluten-free or low-carb diets.

Can I make these sheet pan chicken fajitas ahead of time?

Yes. Marinate the chicken and prep the vegetables up to 24 hours ahead, then roast when you’re ready to eat. Leftovers keep well in the refrigerator for up to four days. Reheat gently in a skillet or oven to preserve texture and flavor.

Is the charred jalapeño crema spicy?

The crema typically has a mild-to-medium kick, depending on the jalapeño. Removing the seeds reduces heat; leaving them in increases it. You can also roast an extra jalapeño for more intensity or use a milder pepper for a gentler flavor.

Notes

• Broiling at the end adds extra char and smoky flavor—watch carefully so ingredients don’t burn.
• Adjust flavors to taste: more citrus for brightness, more smoked paprika for a deeper smoky note, or extra cilantro for freshness.
• If using shrimp, reduce roasting time to prevent overcooking.
• For meal prep, store sauce separately to keep textures fresh.
