Sheet Pan Chicken Fajitas to the Rescue

Ingredients You Need
- Chicken breasts (or thighs): Boneless, skinless, and sliced into thin strips for even cooking.
- Bell peppers: Use a mix of red, yellow, and green for a colorful dish.
- Onion: Adds a subtle sweetness when roasted.
- Olive oil: Helps the seasoning stick and ensures everything gets a nice char.
- Fajita seasoning: A blend of chili powder, cumin, smoked paprika, and garlic powder for that signature fajita taste.
- Lime juice: Brightens everything up with fresh citrus flavor.
- Tortillas & toppings: Warm flour or corn tortillas, guacamole, sour cream, salsa, shredded cheese, and fresh cilantro.
How to Make Sheet Pan Chicken Fajitas
Step 1. Prep the Ingredients. Slice the chicken, bell peppers, and onions into thin, even strips for quick, uniform cooking.
Step 2. Season Everything. In a large bowl, toss the chicken and veggies with olive oil, fajita seasoning, and fresh lime juice until evenly coated.
Step 3. Arrange on a Sheet Pan. Spread everything out on a large sheet pan in a single layer to ensure even roasting. Avoid overcrowding—use two pans if needed.
Step 4. Bake to Perfection. Roast in a 425°F oven for 18-22 minutes, flipping halfway through, until the chicken is fully cooked and slightly caramelized on the edges.
Tips for the Best Baked Chicken Fajitas
- Slice Everything Evenly – This ensures the chicken and veggies cook at the same rate.
- Don’t Overcrowd the Pan – Spread everything out so it roasts instead of steaming.
- Broil for Extra Char – If you love that sizzling, restaurant-style finish, broil for 1-2 minutes at the end for a nice char.
- Use Chicken Thighs for Extra Juiciness – They stay incredibly moist and flavorful.
- Make It Spicy – Add a pinch of cayenne pepper or a sliced jalapeño for some heat.
Serving Ideas & Toppings
- Classic Style: Warm tortillas, fresh lime wedges, and shredded cheese.
- Low-Carb: Serve over cauliflower rice or in lettuce wraps.
- Burrito Bowl: Pair with rice, black beans, and guacamole.
- Breakfast Fajitas: Scramble some eggs and serve the fajita mix over them.

Hi Molly, I made this and your shrimp sheet pan fajitas at the same time! Probably could have made it easier on myself, but I think all of the ingredients in the shrimp one is required, and this chicken sheet pan fajitas came out so well and was so delicious. All the flavors were so great. Really easy and so delicious! I made a delicious black bean side to go with that and made homemade guacamole so it was a wonderful night for everybody
Thanks, Barbara!
This looks yummy.
How many servings in this recipe? I see the serving size is 1 gram, but not the number of servings. Also, are the tortillas part of the 230kcal count?
Hey Mary! This recipe serves 5. The calories count includes the tacos but it depends on what tacos you buy. The nutrition information is an approximation!
Quick and easy meal that my whole family loved! This will be a new staple meal for us! Thank you!
I thought with pcos you should stay away from “white carbs” like white tortillas in this recipe. Am I wrong? I want to make this!
I was wondering if you could use cooked turkey instead of chicken?
Made this tonight it was so simple and soooo good!
Love that, Keesha! Thanks!
I’ve made this a few times now! It’s a super easy weeknight meal that the whole family loves! Thank you!
I was looking for an easy mid-week sheet pan dinner and I came across your recipe. I made it and it was a great success. My kids loved it and so did I. It was delicious. I love sheet pan meals – I’m always trying to save time (or maybe we’re just always running late for meals). Anyway, I’ll be making this again.
Thanks Edwina! So glad you and your kids loved it! It’s one my faves. I don’t think it’s just you—I’m always trying to save time too, especially during the week. I also have an easy sheet pan sausage and veggies recipe if you need any more!
