Sheet Pan Chicken Fajitas are a Fabulous Weeknight Meal!
One area that I have struggled with through the years is healthy dinners.
Historically, I do great with meals for the whole family at breakfast and lunch. By dinner time, everything falls apart.
I get up so early (3:30 am) that by 6 pm I rarely feel motivated to cook a full meal. Because of this, I have a strong preference for meals that can be prepped early in the day (or even on the weekend) and pulled out at dinner time.
I am happy with salads and bowls, but the boys and hubby want a "meal"
One way that I've found that works for our family is sheet pan dinners.
These Sheet Pan Chicken Fajitas are jam-packed with flavor and the perfect balance between healthy and comfort food. You can pile on the cheese and sour cream, or skip it all together. (Or get crazy and make a yogurt sauce.)
I like to make a double batch so that I have chicken and vegetables to throw on a bowl or even a salad later in the week. (This requires two large pans because you don't want to crowd things.)
Next time you know you need a quick and easy meal that the whole family will approve of, give these Sheet Pan Chicken Fajitas a try!
It's like getting dinner and lunch prep done at the same time. #winning
How to Make Sheet Pan Chicken Fajitas
1 First, cut the chicken breast into strips and place in a shallow dish.
2 Next, whisk together the lime juice, avocado oil, garlic, and Southwestern seasoning in a small bow. Reserve 3 tablespoons of the marinade and pour the remaining marinade over the chicken. Marinate for 30 minutes and up to 2 hours.
3 While the steak marinades chop your vegetables.
4 Place a sheet pan in the oven and preheat the oven to 400 degrees. Carefully remove the sheet pan from the oven and arrange the chicken, onions, and peppers on the sheet pan. Bake for 25 to 30 minutes, brushing halfway through with the reserved marinade.

How Do I Season Chicken for Fajitas?
There are several ways that you can choose to season chicken for fajitas.
1. I've used a homemade marinade that uses a Southwestern seasoning blend. This gives you all the benefits of the taste of a homemade marinade without having to mix up a custom spice blend.
2. You can purchase a packet of Fajita seasoning.
3. You can make a marinade with a custom fajita seasoning blend. Here is a good example.
Are Fajitas Healthy?
Fajitas can undoubtedly be a part of a healthy diet, provided the portion size is sensible. If you are watching calories, you want to pay close attention to the amount of cheese and sour cream you use. Go heavy on the veggies, and keep the chicken to a 4-ounce serving or less. Another option is to skip the tortilla and serve over a bed of greens.
Tips
- If You don’t have Southwestern Seasoning, use 1 teaspoon chili powder, ½ teaspoon each cumin, garlic powder, salt, and paprika. Fajita season or taco seasoning also work.
- I use organic flour tortillas for the family, and gluten free organic corn tortillas for myself.
Variations
- Cut a zucchini and yellow squash into matchsticks and toss with a tablespoon of olive oil. Sprinkle with salt. Add to the Sheet Pan Chicken Fajitas in the last five minutes of cooking.
- For a little more heat, add in ½ teaspoon crushed red pepper to the marinade.
- Serve with Avocado Cream or Bacon Guacamole.
- Instead of serving with cheddar cheese, serve with crumbled quasi fresco or grated Monterey Jack Cheese
