I think sheet pan meals are the ultimate weeknight solution. What could be easier than everything tossed together, poured onto one pan, and popped in the oven? Weeknight dinner - done in a flash!
Just as great as the easy prep and cooking, using a sheet pan also means clean-up is a breeze! Just one sheet pan (plus a knife and a cutting board) to wash and you are done with the dishes.
Ingredient Notes
The full list of ingredients and quantities can be found in the recipe card below.
- Boneless, skinless chicken breast: You can also use chicken tenders if you don't want to spend time slicing the chicken. Some grocery store meat counters will also slice chicken breast for you.
- Bell peppers: I suggest red and yellow for this recipe but any type of bell pepper works in fajitas.
- Cilantro: Fresh cilantro is a must for this recipe. If you don't like cilantro you can add some extra lime juice but leaving it out will change the taste of the finished dish.
- Taco seasoning: You can make my favorite taco seasoning or use a pre-made seasoning of your choice.
- Corn tortillas: Taco-size tortillas are ideal for fajitas as well. You can use flour tortillas if you prefer.
- Guacamole: Use your favorite recipe or buy it pre-made at the grocery store. You can substitute sliced avocados.
Put these fajitas on your meal plan for next week. They are packed with flavor and make a great way to kick off Taco Tuesday in the new year!
How to make this recipe
When I think about the ideal weeknight meal, it's something that's easy and doesn't require a ton of hands-on time. Sheet pan meals generally tick both of those boxes - which means they are ideal for a weeknight dinner.
- Prep the veggies. You start this dish by adding the sliced veggies to one half of a baking sheet and tossing them with oil, salt and pepper.
- Season the chicken. Then you'll season the chicken by tossing it with olive oil and taco seasoning. If you want to keep this a true one-pan recipe, you can do this right on the baking sheet, though I typically use a small bowl to pre-mix the taco seasoning and the oil.
- Bake the fajitas. Bake the peppers, onions and chicken for about 20 minutes, stirring once after about 10 minutes.
- Heat the tortillas. I like to sear my tortillas a bit to heat them. You can do this on an outdoor grill, in a grill pan on the stovetop, or directly on your stove burner if you have a gas stove. Use caution with the last method to make sure they don't catch fire! You can also wrap them in aluminum foil and warm them in a 300°F oven.
Step 5 | Finish and serve. Once the fajita mixture is finished baking, remove the pan from the oven and drizzle the chicken and veggies with lime juice. Then assemble the fajitas and serve immediately.
Additional Notes from the Kitchen
- Try to slice the veggies and chicken to a similar size and thickness to ensure everything cooks evenly.
- Always use a rimmed sheet pan, or a half sheet pan, to avoid messes. I also like to line the pan with parchment paper to make clean-up even easier!
Serving Suggestions
Once the chicken and veggies are done baking and the tortillas are warmed, just add cheese, guacamole and any other toppings you like! I typically use corn tortillas for fajitas but you can sub flour tortillas if you prefer.
You can top these fajitas with pretty much anything you like - guacamole, pico and a bit of Greek yogurt or sour cream are my favorite options.
Fajitas are essentially a meal on their own but if you want to add a side that can double as a topping this Grilled Corn Salsa works well.

I LOVE sheet pan dinners! After a long day chasing two toddlers around the last thing I want to do is tons of dishes! I can’t do grains or corn but I think I’ll turn these into fajita bowls with cauliflower rice!!
FoodieGirlChicago
I think they would be great over cauliflower rice as well!

We are on the same brain wavelength - I can't stop making sheet pan steak fajitas (and I finally took the time to photograph them last week so I can get them up on the blog soon). I love how easy sheet pan dinners are, and that I can prep everything the night before, leave the sheet pan in the fridge, and pop it straight into the oven when I get home from work. SO EASY!

Yep no question, this is the ultimate weeknight meal. I tend to add a little extra cayenne pepper to mine for that extra burst of spice but it is so easy to prepare and so good!
