Ingredients
Main Ingredients
- 1 lb (450g) boneless, skinless chicken breasts, sliced into thin strips
- 1 red bell pepper, sliced
- 1 yellow bell pepper, sliced
- 1 green bell pepper, sliced
- 1 medium red onion, sliced
- 3 tablespoons olive oil
The chicken gives this dish its protein. I love using boneless, skinless chicken breasts for their lean quality. The bell peppers add color and sweetness. I prefer a mix of red, yellow, and green for a vibrant look. The red onion adds a nice zing. Olive oil helps everything cook well and adds flavor.
Seasonings
- 2 tablespoons fajita seasoning (store-bought or homemade)
- 1 teaspoon garlic powder
- 1 teaspoon cumin
- Salt and pepper to taste
The fajita seasoning is key. It brings that classic flavor we love. Garlic powder adds depth, while cumin gives warmth. Salt and pepper are essential to enhance all the flavors. You can adjust these to match your taste.
Serving Essentials
- Tortillas (flour or corn) for serving
- Fresh cilantro, chopped (for garnish)
- Lime wedges (for serving)
Tortillas are a must for serving. They hold all the goodness. Fresh cilantro adds a pop of flavor and looks great on the plate. Lime wedges let you squeeze fresh juice over your fajitas. This brightens the dish and balances the flavors.

Step-by-Step Instructions
Preparation Steps
1. Preheat the oven
Set your oven to 425°F (220°C). This step is key for perfectly cooked fajitas.
2. Combine ingredients in a bowl
In a large bowl, mix the sliced chicken, red bell pepper, yellow bell pepper, green bell pepper, and red onion. This blend gives great color and flavor.
Cooking Process
3. Drizzle and season the mixture
Pour 3 tablespoons of olive oil over the chicken and veggies. Then, sprinkle 2 tablespoons of fajita seasoning, 1 teaspoon of garlic powder, 1 teaspoon of cumin, and add salt and pepper. Toss everything until well coated. This ensures each bite is packed with flavor.
4. Spread on the baking sheet
Line a large baking sheet with parchment paper or foil. Spread the chicken and vegetable mixture in one layer. This allows them to cook evenly and get that nice char.
Baking Instructions
5. Bake and monitor cooking time
Place the sheet pan in the preheated oven. Bake for 20-25 minutes. Stir halfway through for even cooking. Check that the chicken is cooked through and the veggies are tender.
6. Cooling and serving recommendations
Once done, take the sheet pan out and let it cool for a few minutes. Serve the fajitas hot on warm tortillas. Top with chopped cilantro and a squeeze of fresh lime juice for a burst of brightness.
Tips & Tricks
Cooking Tips
To get the perfect chicken texture, slice your chicken thin. Thin strips cook fast and stay juicy. Use a meat thermometer; chicken should reach 165°F (75°C).
For tender vegetables, cut them into equal sizes. This helps them cook evenly. Stir halfway through baking for the best results. You want them soft, but still colorful and crisp.
Serving Suggestions
Serve your fajitas family-style on the baking sheet. This makes it fun and easy for everyone to help themselves. Place warm tortillas alongside. It adds to the experience!
Garnishing can elevate your dish. Use fresh cilantro for a pop of flavor. Lime wedges add a zesty touch that brightens the whole meal.
Cleanup Tips
Cleanup can be a breeze with these tips! Line your baking sheet with parchment paper. It prevents sticking and makes cleanup easier.
If you use foil, make sure to fold it neatly. This helps catch drips and makes for a quick cleanup. Either way, you’ll save time and effort!
Pro Tips
- Marinate for Flavor: For an extra burst of flavor, marinate the chicken in the fajita seasoning, olive oil, and lime juice for at least 30 minutes before cooking.
- Veggie Variations: Feel free to mix in other vegetables like zucchini, mushrooms, or corn for added texture and taste.
- Serve with Sides: Complement your fajitas with sides like guacamole, salsa, or sour cream to enhance the dining experience.
- Perfect Tortillas: Warm your tortillas on a skillet for a few seconds on each side before serving to make them more pliable and flavorful.
Variations
Ingredient Variations
You can easily change the main protein in this dish. Swap chicken for shrimp or beef. Shrimp cooks fast and adds a nice twist. Beef gives a heartier flavor.
You can also use different vegetables. Try zucchini, mushrooms, or corn. Each veggie brings its own taste and texture. Mix and match to find your favorite combo.
Flavor Variations
If you wish to make your own seasoning, it’s simple. Combine chili powder, paprika, and onion powder for a tasty mix. You can also add garlic powder and cumin for depth. This way, you control the spice level.
Want more heat? Add jalapeños to the mix. Slice them thin and toss them in with the other veggies. They will give your fajitas a spicy kick!
Dietary Variations
For a gluten-free meal, use corn tortillas instead of flour ones. They taste great and fit your diet. Check labels to ensure all ingredients are gluten-free.
Looking for a low-carb option? Skip the tortillas altogether. Serve the fajitas over a bed of lettuce. You’ll still enjoy all the flavors without the carbs.
Storage Info
Leftover Storage
To keep your chicken fajitas fresh, store them properly. First, let the fajitas cool to room temperature. Then, place them in an airtight container. This helps seal in the flavor and moisture. Make sure to refrigerate them within two hours of cooking.
- Use shallow containers for quick cooling.
- Label containers with dates to track freshness.
Reheating Instructions
For reheating, you want to keep the fajitas tasty. The best method is using the oven. Preheat it to 350°F (175°C). Spread the fajitas in a single layer on a baking sheet. Heat for about 10-15 minutes until warm.
You can also use a microwave. Put the fajitas in a microwave-safe dish. Cover them with a damp paper towel. Heat in short intervals, stirring in between, until warm.
- Check that the chicken reaches at least 165°F (74°C) to ensure it’s safe to eat.
- Add a splash of lime juice to brighten the flavor when reheating.
Freezing Tips
If you want to save fajitas for later, freezing is a great option. First, let the leftovers cool completely. Then, place them in freezer-safe bags or containers. Remove as much air as possible to prevent freezer burn.
- Freeze in portion sizes for easy meals later.
- Label bags with dates for easy tracking.
When you’re ready to eat, thaw the fajitas in the fridge overnight. Reheat them in the oven or microwave as described above. This method helps maintain their texture and flavor.
FAQs
How do I know when the chicken is cooked?
To check if the chicken is cooked, use a meat thermometer. The safe internal temperature for chicken is 165°F (74°C). Insert the thermometer into the thickest part of the chicken. If it reads 165°F, the chicken is ready. This step ensures your chicken is safe to eat and juicy.
Can I use a different cooking method?
Yes, you can! If you don't want to use a sheet pan, try grilling or sautéing. For grilling, heat the grill to medium-high and cook the chicken and veggies until done. If you sauté, use a large skillet over medium heat. Both methods will give you tasty fajitas.
