Ingredients - Notes & Substitutions

Here’s what you need to make these juicy and delicious sheet pan fajitas:

Chicken: I prefer chicken tenders since they require minimum prep and are the right size for this recipe. If they are too thick, cut them in half ’length-wise’. If using boneless, skinless chicken breasts, cut each breast lengthwise into ½-inch thick pieces, and if those slices are too wide, cut them in half. Veggies: Peppers and onions are the classic Mexican fajita vegetables. While filming this recipe, I used one red and one yellow pepper, but any color assortment will do. For a bit more spice, replace one bell pepper with a poblano pepper instead. Taco Seasoning: I like to make a homemade blend of fajita seasoning since I can customize the salt and heat levels. To make that, you will need salt, ground cumin, ground coriander, garlic powder, Mexican chili powder, paprika, dried oregano, and cayenne. Alternatively, use 2 to 3 Tablespoons of your favorite store-bought taco seasoning (I prefer Trader Joe’s brand).

How to Make Sheet Pan Chicken Fajitas

This recipe is as simple as season, cook and serve! Here are the step-by-step instructions and photos:

Step 1: Prepare Homemade Taco Seasoning

In a small bowl combine salt, ground cumin, ground coriander, garlic powder, Mexican chili powder, paprika, dried oregano, and cayenne. This recipe for homemade fajita seasoning is good for 1 to 1.5 pounds of protein plus veggies. Skip this step if using store-bought taco seasoning.

Step 2: Season Chicken, Onions & Peppers

In a large mixing bowl or a gallon-size ziplock bag (easy clean-up), add chicken tenders, sliced peppers, and onions. Add avocado or canola oil and toss well using tongs. Coating with oil first allows the spices to stick evenly. Now add salt and seasoning and toss until everything is coated evenly. If using a ziplock bag, seal the ziplock bag and shake the bag till well coated.

Step 3: Roast in the Oven

Turn the oven on HIGH Broil mode. Spread the seasoned chicken, peppers, and onions evenly on an aluminum foil-lined baking sheet. Avoid using parchment paper as the edges might burn. Place the baking sheet on the top layer, making sure there’s a 2.5 to 3-inch clearance from the broiler plates, or else the chicken will burn. Broil for 10-12 minutes, or until chicken is cooked through. Check the chicken at the 10-minute mark.

Serving Suggestions

This sheet pan fajitas chicken recipe is incredibly versatile. Feel free to serve it as follows:

The Best Fajita Topping Sauces: Drizzle a generous portion of one or more of the following topping sauces, such as Pico De Gallo, Creamy Avocado Dressing, Guacamole, Restaurant-Style Salsa, or Mango Salsa. Burritos: Warm flour tortillas over the stovetop or wrap them in foil and warm in the oven while the chicken is broiling. Fill and top with your favorite condiments and gently roll into a flavor-packed burrito. Tacos: Place crispy yellow or blue corn taco shells onto a baking sheet and toast in the oven during the last 2 minutes of cooking time. Fill, dollop, and drizzle to enjoy as crunchy tacos. Enchiladas: Microwave corn tortillas in the microwave on HIGH for 30 seconds. Lightly oil a 13 x 9-inch casserole dish and coat the bottom with a ladle of enchilada sauce (a 12-oz store-bought jar will do). Dip each tortilla in the enchilada sauce, then scoop ¼ cup of the chicken mixture into each tortilla, gently roll, and place in the pan, seam side down. Top with remaining enchilada sauce and 1 cup shredded Cheddar, Monterey Jack, or a blend of Mexican cheeses. Bake for 15 minutes in a preheated 350-degree oven and garnish with cilantro, sour cream, or your favorite toppings! Tostadas: Spread 8 corn tortillas out on a foil-lined baking sheet. Lightly spray with oil, and season with salt. Bake in preheated 400-degree oven for 8 minutes, flipping halfway through. Top with the chicken fajita mix and your favorite toppings. Serve with accompaniments: Serve with a side of Mexican rice or Mexican quinoa, and Creamy Black Beans for a simple weeknight meal. Low-Carb Fajitas: Serve the fajitas in almond flour tortillas, or over a bed of greens or crisp lettuce cups, such as romaine, baby spinach, or butter lettuce.

How to Store

Store chicken fajitas in an airtight container and refrigerate for up to 5 days. To reheat, simply heat in the microwave for 30 to 45 seconds. I do not recommend freezing chicken fajitas as the onions and peppers become extremely soggy after defrosting and do not taste good.

Recipe Tips & Notes

Substitute chicken tenders with 1-lb boneless, skinless chicken breasts or thighs. Cut each breast lengthwise into ½-inch thick pieces, then cut that in half, width-wise. If you prefer dark meat, use an equal amount of boneless, skinless chicken thighs, following the same slicing guidelines. Taco seasoning: I prefer the flavor and aromatic quality of homemade fajita seasoning, so highly recommend it. Alternatively, use 2 to 3 tablespoons of your favorite store-bought seasoning packet instead. I like Trader Joe’s brand. Bake in one even layer. For even cooking, use a large enough sheet pan so the chicken and vegetables can be spread into a single layer. Air Fryer Instructions: To make fajitas in the air fryer, follow the detailed instructions listed here: air fryer chicken fajitas. Meal Prep and use in a variety of meals: Make a double batch and transform the fajitas into burritos, tacos, enchiladas, or tostadas. Follow the instructions above to create a fun and creative Mexican meal. For low-carb fajitas, serve the chicken mixture in almond flour tortillas, or over a bed of greens or crisp lettuce cups, such as romaine or butter lettuce.
