Dinner tonight is Sheet Pan Chicken Fajitas! This easy dinner recipe is a family favorite! A flavorful seasoning mix + a rainbow of veggies make this sheet pan dinner delicious! (Gluten-Free, Dairy-Free)
Can we all agree that fewer dishes to wash is an amazing thing?
I love tossing sheet pan dinners or one-pan dinners into our rotation for crazy nights. It’s just SO NICE to have simple, easy dinner recipes AND not to have too many dishes to wash! (THREE CHEERS FOR EASY CLEAN UP!)
It’s a huge bonus when that dinner tastes as amazing as these Sheet Pan Chicken Fajitas.
Thin strips of tender chicken are tossed with a smoky, savory spice blend and a rainbow of colorful fresh vegetables then tossed into the oven on a sheet pan for a simplified, hands-off healthy dinner. They’re not traditional, but they ARE crazy easy and delicious.
Did I mention the fewer dishes thing? Because… so great. Even better? This easy recipe starts with simple ingredients. Here’s what you need to make some seriously yummy sheet pan chicken fajitas…
Gather Your Ingredients
One thing you’ll love about these easy chicken fajitas is how simple the ingredients list is! It makes for minimal prep and keeps things easy. Let’s take a look:
- CHICKEN. I use boneless, skinless chicken breast for these gluten-free chicken fajitas, but chicken thighs will also work. I cut it into thin slices (about 1/2″ wide). This helps the chicken cook evenly.
- A TRIO OF BELL PEPPERS. These sheet pan chicken fajitas are so pretty and colorful, thanks to a trio of colorful bell peppers. You can use any 3 bell peppers you like, but I like mixing red, green, and yellow bell peppers for a colorful, delicious meal.
- ONION. Similarly, you can choose white or red onion for these sheet pan fajitas. The red onions are so pretty that they’re my go-to!
- CILANTRO. Some fresh cilantro keeps the flavor from getting too heavy. I love the brightness it adds! (If you’re not a cilantro fan, you can skip it)
- A SAVORY SPICE MIX. Here’s where things get fun! I love a blend of chili powder, cumin, onion powder, garlic powder, and smoked paprika to make a quick homemade fajita seasoning. You could probably get by with a packet of taco seasoning or a packet of Siete fajita seasoning, if you prefer!
- LIME JUICE + OIL. Then, I finish things up with a combination of fresh lime juice and a little oil. It keeps things bright and keeps the chicken fajitas from sticking to the pan. You can use olive oil or avocado oil for this recipe. Your choice!
How To Make Sheet Pan Fajitas, Step By Step
As always, you can find the full recipe, with ingredient amounts, detailed instructions, and tips in the recipe card below!
- Preheat oven to 425 degrees F. Lightly grease a sheet pan and set aside.
- Make Seasoning Mix. In a small bowl, combine chili powder, cumin, garlic and onion powder, smoked paprika, and salt.
- Combine Fajitas Mixture. In a large bowl (or right on the baking sheet if you want to save a dish), combine bell peppers and onion. Add chicken and cilantro. Sprinkle with spice mixture, and drizzle with lime juice and oil. Toss with tongs or your hand to combine well.
- Roast. Spread fajitas mixture out on a baking sheet in a single layer. Bake at 425 degrees F. for 25-30 minutes, or until chicken is cooked through and peppers and onions are starting to char. (If you want, you can put the pan under the broiler for 1-2 minutes at the end to get more charring.)
- Serve & Store. Serve the fajitas in tortillas with guacamole, salsa, sour cream or crema, or spoon onto burrito bowls or taco salads with your favorite toppings. Leftover fajitas can be stored in an airtight container in the fridge 3-4 days.
What To Serve With These Fajitas
If you want to fill this out a bit, here’s how I make my sheet pan chicken fajitas into a whole meal.
- WARM TORTILLAS. You can use corn tortillas or flour tortillas, based on your preference or dietary needs. We’re gluten-free, and I like Mission gluten-free tortillas. (See the FAQ for a paleo/non-tortilla option!)
- GUACAMOLE. I will never say no to a chance to eat guacamole. It’s really nice here next to the chicken and peppers mixture. (Avocado slices also taste great!)
- PICO DE GALLO OR SALSA. I love to finish these with pico de gallo or salsa. So bright and fresh!
- BEANS (OR BEANS & RICE). Some seasoned black beans (or some Charro beans and Mexican restaurant rice!) on the side makes me feel like I’m at a restaurant instead of my kitchen!
- SOME FRESH FRUIT OR FRUIT SALAD. For a light, refreshing side dish, I love adding some fresh fruit (pineapple or watermelon are nice!) or fruit salad. This honey lime fruit salad is so light and cool. It’s a delicious complement to the heat and spices of the fajitas.
FAQ + Tips For The Best Sheet Pan Chicken Fajitas
PRO TIP: CUT EVERYTHING THE SAME THICKNESS. One big tip to help your sheet pan chicken fajitas cook evenly is to cut things the same thickness. I like 1/4″ thick strips of peppers and onions and 1/2″ thick strips of chicken. It’ll help things cook at the same rate.
WANT MORE CHAR? BROIL IT AT THE END! Since you won’t get a traditional char from the fajitas-style cooking in a pan on the stove, you can mimic this effect by putting the fajitas under the broiler for 1-2 minutes at the end of the cooking time. Watch the mixture carefully so it doesn’t burn!
PALEO? WATCHING CARBS? You can totally serve this fajita mixture in a paleo burrito bowl with some cilantro lime cauliflower rice, or wrapped in Siete grain-free tortillas. You can even turn it into a fajitas “taco salad” by putting the fajitas mixture on a big bed of lettuce, with some guacamole and pico de gallo.
