What You’ll Need

Are those pictures making you hungry yet? I’m right there with you. Here’s what we’ll need to get started. Scroll down to the recipe card for exact amounts.

• Veggies: Grab a red onion and an orange, red, and yellow bell pepper for great flavor and color!
• Olive Oil
• Chicken: We’re using boneless skinless chicken thighs, but chicken breast works too.
• Taco Seasoning: Try making your own using the tips below. But a store brand works fine too.
• Fajita Fixings: We love corn tortillas, pico de gallo, fresh cilantro, jalapeno, limes, and sour cream. But feel free to use any fixings you love!

How to Make Your Own Fajita Seasoning

Ready-made seasoning is totally fine if you’re in a rush, but I strongly recommend making your own if you have a little extra time! Plus, if you make a big batch, it will last you through multiple Taco Tuesdays. To make the seasoning use a combination of the following spices:

• Chili Powder (1 tbsp)
• Onion and/or Garlic Powder (1 tbsp)
• Sea Salt (1 tsp)
• Dried Oregano (1/2 tsp)
• Ground Cumin (1 tbsp)
• Smoked Paprika (1 tbsp)
• Black Pepper (1 1/2 tsp)
• Red Pepper Flakes (optional)

This will provide you with around 1/3 cup of seasoning.

How to Slice the Chicken and Vegetables

Cutting chicken and vegetables into slices can be a bit tricky, so here are a few tips to help you out:

• For the Vegetables: Carefully slice the onion and peppers in half, and then slice the halves into 1/4 inch pieces.
• For the Chicken: Cut the chicken against the grain (the tiny white fibers) in one clean motion, so that the strips will be perfectly tender when cooked.  

How to Make Sheet Pan Chicken Fajitas

Here’s what you’ll need to do to put it all together. Dinnertime has never been so easy! Check out the recipe card at the end of this post for detailed instructions.

• Prepare: Preheat your oven to 400 degrees.
• Veggies: Place sliced vegetables onto a sheet pan and toss them with olive oil and taco seasoning. . Cook for about 5 minutes.
• Chicken: While the veggies are cooking, slice the chicken into ¼ inch slices and then toss them with olive oil and taco seasoning. When the 5 minutes are up, remove the pan from the oven and place chicken onto the sheet pan. Place the sheet pan back in the oven for 15 more minutes or until an instant read thermometer registers 165 degrees.

Tips and Tricks

Now that you know what to do, here are some useful tips on making the best sheet pan chicken fajitas:

• Chicken Thighs vs Chicken Breasts: Chicken thighs are so forgiving as they do not get dry if a little overcooked, but you could use chicken breasts instead.
• Line Sheet Pan: Line your sheet pan with foil for an even easier clean up.
• For Crunchy Vegetables: The vegetables in this recipe get nice and soft, if you like your vegetables with more crunch do not precook them.
• Spread Out Vegetables and Chicken Strips: Make sure you spread them out on the pan so that everything cooks evenly. Also, make sure your chicken gets to 165 degrees before you take the pan out of the oven to avoid undercooked chicken.

What to Serve With Sheet Pan Chicken Fajitas

Wondering what to serve with these sheet pan chicken fajitas? These are a few of my favorite sides:

• Cheesy Taco Beer Dip: A fun appetizer served with chips!
• Grilled Corn: juicy corn on the cob would go great with the other veggies.
• Salad: throw some greens on the side of those fabulous fajitas!
• Sweet Plantains: I know, I know; these are fajitas and fajitas are Mexican. I am from Texas and Jorge is from Puerto Rico and sometimes we mix those backgrounds…and trust me, it’s a delicious mix!

How to Store and Reheat Leftovers

Fajitas are best when eaten warm from the oven on the day they are made, but you can enjoy leftovers if there are any left.

• Store: Preserve them for 3-4 days in an airtight container in the fridge.
• Reheat: To reheat them, toss the chicken and vegetables in a pan until warm again, or simply heat everything up in the microwave for 30 seconds. 
• Freeze: We don’t recommend freezing leftovers since the cooked veggies will get really soft.
