In the past, we’ve fallen into the trap of ordering takeout whenever we were too busy or too tired to cook.

Chicken fajitas are like the healthy older sibling of chicken tacos. They’re full of lean protein, tasty vegetables, and generally not a whole lot else – maybe some homemade guacamoleand shredded cheese. They’re simple yet full of flavor, and even though they look fancy they’re basically just like these shredded chicken tacos with extra veggies. So they’re the perfect alternative for shaking up Taco Tuesdays!

How To Make Easy Sheet Pan Chicken Fajitas In The Oven

Traditionally, the fajita chicken, peppers, and onions would be grilled and served in a hot cast iron pan with tortillas and toppings on the side. However, let’s make this easy. If you’re baking the chicken, then you might as well bake the vegetables too – and while you’re at it, why not throw it all on one pan?

1. Prep the seasoning blend
2. Slice the peppers and onions
3. Lay the chicken tenders*, peppers, and onions out on a sheet pan and sprinkle with the seasoning blend
4. Finish with lime juice, salt, and pepper
5. Bake until cooked through
6. Slice the chicken
7. Serve with warm tortillas and toppings!

Note: Raw chicken can sometimes be extra juicy, so try to let as much excess liquid drip off the chicken before it goes onto the baking sheet. (You can even try patting it dry with paper towels if it’s extra gross). This will prevent the peppers and onions from getting soggy while they cook.

What Makes These The Best Sheet Pan Chicken Fajitas

• One baking sheet = only one pan to clean after dinner (or no pans to clean, if you line it with foil like we do!)
• Cooking the peppers and onions with the chicken means extra flavor from all the seasonings you would normally only put on the chicken
• We had 15 minutes of hands-off cooking time to prep the guacamole and tortillas, and relax a little
• The entire meal took only 20 minutes to make
• Chicken fajitas are delicious, healthy, and filling!

This recipe really was the perfect solution for a quick dinner on busy weeknights. The fact that it only took 20 minutes and required virtually zero cleanup was amazing in and of itself, but made even better by how tasty it was.
