Important Note About The Sheet Pan
It's important to note that I'm using a big sheet pan here, not a standard-sized cookie sheet. If you only have standard-sized cookie sheets, you can cook the potatoes on one pan and the chicken and veggies on another.
Tips For The Best Sheet Pan Fajitas
- Cut matters - cut the potatoes into small cubes so they cook evenly with the chicken
- Don't overcrowd the pan - use a large sheet pan so everything roasts instead of steams
- Adjust spice for adults - The base seasoning is mild, but you can add hot sauce at the table for adults who like it spicy
- Broil for extra color: A quick 2-3 minutes under the broiler will caramelize the veggies a little bit, if you like it more browned
Serving Ideas

These fajitas are incredibly versatile. Try them with these suggestions:
- Wrapped in warm tortillas
- Served as a fajita bowl
- Tucked into lettuce wraps for a lower-carb option
- Over some rice, quinoa, or beans
- Topped with avocado, cilantro, dairy-free sour cream, or a drizzle of ranch.
- Alongside tomato avocado salad
Make-Ahead & Storage Tips
- Make it for meal prep: Store leftovers in an airtight container for up to 4 days.
- To reheat: Warm it in a skillet on the stove, in the oven at 300°F for 5-10 minutes, or in the microwave until heated through.
- Prep ahead: Chop the veggies and mix the seasoning the night before to save time.

Serving Your Fajita Sheetpan
- In my house, the men like to put the chicken and veggies into a tortilla and top with fresh avocado and cilantro, then have the potatoes on the side. I'm watching my macros, so I skip the tortilla and serve mine in a bowl with avocado, cilantro, and some fresh lime slices.
