Slice the Chicken: Begin by cutting the chicken breast into thin strips. A sharp knife will make this task easy, preparing the chicken to soak in those marvelous flavors.

Prepare the Vegetables: Next, slice the bell peppers and onion into strips, ensuring they’re roughly the same thickness for even cooking. The bright colors will bring your dish to life!
-
Heat the Oil: In a large skillet, heat the olive oil over medium heat. Allow the oil to warm up and shimmer; this means it’s ready for cooking.

How to Store and Freeze One-Pan Chicken Fajitas
Fridge: Store any leftover one-pan chicken fajitas in an airtight container in the fridge for up to 3 days to maintain their flavor and freshness.
Freezer: If you want to freeze the fajitas, place the chicken and pepper mixture in a freezer-safe bag, removing as much air as possible. They can be frozen for up to 3 months.
Reheating: To reheat, thaw overnight in the fridge, then warm in a skillet over medium heat until heated through, making sure not to overcook.
Tortillas: If you’ve made extras, wrap tortillas tightly in plastic wrap and store in the fridge for up to a week or freeze them for longer freshness.
Tips for the Best One-Pan Chicken Fajitas
-
Perfectly Slice Chicken: Ensure the chicken is cut into even strips for consistent cooking, allowing the flavors to blend beautifully.
-
Fresh Ingredients: When possible, use fresh bell peppers and onions for a vibrant taste. Frozen veggies can become mushy and lose their crunch.
-
Watch the Heat: Keep the skillet on medium heat; high heat can scorch the chicken and veggies, compromising their delightful texture and flavor.
-
Customize Seasoning: Feel free to adjust the fajita seasoning based on your preference—add extra spice for a kick, or keep it mild for the kiddos.
-
Warm Tortillas: Warm your tortillas in a pan or microwave before serving; this enhances their flavor and makes them easier to wrap around the filling.
Make Ahead Options
These one-pan chicken fajitas are perfect for meal prep enthusiasts looking to save time during busy weeknights! You can slice the chicken and vegetables (bell peppers and onion) up to 24 hours in advance, storing them in airtight containers in the refrigerator to maintain their freshness. If you’re planning further ahead, the sliced ingredients can also be prepped 3 days prior; just be sure to keep the chicken separate from the vegetables to prevent any moisture transfer. When you’re ready to whip up your meal, simply heat a skillet, add the olive oil, and cook the chicken until browned, then toss in the veggies and fajita seasoning until everything is tender and delicious. You’ll enjoy flavorful, restaurant-quality results with minimal effort!

One-Pan Chicken Fajitas Recipe FAQs
How do I choose ripe bell peppers?
Absolutely! For juicy, sweet bell peppers, look for ones with a firm texture and vibrant color. Avoid any that have dark spots or wrinkles—those are signs of aging. Ideally, you want them to feel heavy for their size, indicating their freshness and juiciness.
How should I store leftover one-pan chicken fajitas?
Store your leftovers in an airtight container in the refrigerator. They’ll stay fresh for up to 3 days. Just make sure to let the chicken and veggie mixture cool down to room temperature before sealing it away, as this helps maintain their delicious flavors.
Can I freeze one-pan chicken fajitas?
Very! To freeze, first let the chicken and veggies cool completely. Then, transfer them to a freezer-safe bag, pressing out as much air as possible. This way, they’ll keep well for up to 3 months! When you’re ready to enjoy them again, simply thaw overnight in the fridge and reheat in a skillet.
What should I do if my chicken is tough?
If your chicken turns out tough, it’s likely overcooked. To ensure tender chicken next time, try slicing it against the grain and keeping close watch while cooking. Aim for an internal temperature of 165°F and remove it from heat as soon as it reaches that temperature. Quick cooking over medium heat helps lock in moisture!
Are these fajitas safe for children and pets?
Absolutely! However, if your little ones or pets are sensitive to spice, reduce the fajita seasoning or try a mild variant. Always check the ingredients used to ensure they’re safe; for pets, avoid ingredients like onions, which can be harmful.
