Which ingredients do we need?
Seriously, this is such an easy recipe and you can really make do with what you have in the fridge. Traditional fajitas have bell peppers and onions, but I couldn’t resist throwing in some zucchini and mushrooms.
Here’s what you need for chicken fajitas
- chicken breast– cut into strips (1×2 inches).
- veggies– bell peppers and onions sliced into strips. Add in quartered mushrooms and zucchini strips as well if you’d like!
- fajita seasoning– you can purchase pre-made fajita seasoning for a shortcut, or make your own.
- olive oil & lime juice
- toppings– we love adding fresh cilantro and avocado slices. See below for more delicious fajita toppings!
Tips for perfect fajitas
Some serving suggestions:
- cilantro
- avocado slices or guacamole (see how to cut an avocado here)
- salsa or pico de gallo
- sour cream or greek yogurt
- cheese (not authentic but my kids love it)
- pickled onions or jalapenos
Prep ahead and eat later
You can meal prep this recipe in one of two ways:
- Assemble ahead– you can pre-slice your veggies and chicken, toss in olive oil, lime juice and seasoning, and store in an air tight container in the fridge for 2-3 days.
- Check the expiry date on your chicken before storing to make sure it is safe to store uncooked for this period of time.
- when you are ready to cook, simply spread out on a sheet pan and bake for 15-20 minutes!
- Cook ahead– these sheet pan chicken fajitas were one of our Lunch Prep Challenge recipes back in 2017. Cook ahead, portion out into 2 cup meal prep containers, and reheat as needed for lunches or dinners. It would freeze well, too!
- for eating at lunch, I like serving with a tortilla boat, as it’s less messy. Keep tortillas and filling separate until you are ready to serve.
Can I swap the bell peppers or onions?
Yes, you definitely could do that. Replace with vegetables that will roast through in 15 minutes such as mushrooms, zucchini, small cut broccoli or cauliflower, halved brussels sprouts, or green beans. These are not in any way traditional ingredients, but would work if you are trying to clean out the fridge.
-
- roasted sweet potato cubes would be tasty in sheet pan fajitas, but require closer to 25 minutes to cook through in the oven
- portobello mushrooms are great for a vegan version of this recipe; check out these Portobello Fajita Vegan Meal Prep Bowls (omit the quinoa and use tortillas)
Can I freeze this recipe?
After cooking- yes. Before cooking- I think it will work as a freezer to sheet pan meal, but haven’t tried. Thaw completely before spreading out on a sheet pan and cooking as directed.
Can I make these fajitas low carb or keto?
Swap the sugar for either monk fruit sweetener (around 1/4 of the amount), or leave out altogether.
