What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, so you probably have them on hand already.

• Chicken: 1.5 pounds (680g) boneless, skinless chicken breasts or thighs, sliced into thin strips (thighs add more juiciness!)
• Bell Peppers: 3 medium (about 450g), a mix of red, yellow, and green, sliced into strips (adds vibrant color and sweetness)
• Onion: 1 large yellow or white onion, thinly sliced (adds depth and natural sweetness)
• Olive Oil: 2 tablespoons (I prefer extra virgin for flavor)
• Garlic Powder: 1 teaspoon (for that subtle, savory kick)
• Chili Powder: 2 teaspoons (adds smoky warmth)
• Cumin: 1 teaspoon (classic fajita spice)
• Paprika: 1 teaspoon (smoked if you want a deeper flavor)
• Oregano: ½ teaspoon (Mexican oregano preferred if you can find it)
• Salt: 1 teaspoon (adjust to taste)
• Black Pepper: ½ teaspoon freshly ground
• Lime Juice: Juice of 1 lime (about 2 tablespoons) added after cooking for a bright finish
• Fresh Cilantro: A handful, chopped (optional, for garnish)
• Tortillas: Flour or corn, warmed, for serving

If you want to swap chicken for shrimp or tofu, that works great too! Use almond flour for a gluten-free option when warming tortillas, or swap olive oil for avocado oil if you prefer a higher smoke point. I usually recommend brands like McCormick for spices because they’re consistent and fresh, but feel free to use what you love.

Equipment Needed

• Baking Sheet: A large rimmed sheet pan (around 18×13 inches / 46×33 cm) to spread out the chicken and veggies evenly.
• Parchment Paper or Silicone Baking Mat: Optional but helpful for easy cleanup and preventing sticking.
• Mixing Bowl: For tossing chicken and veggies with spices and oil.
• Sharp Knife and Cutting Board: For slicing chicken, peppers, and onion.
• Tongs or Spatula: For turning ingredients halfway through roasting.

If you don’t have a rimmed baking sheet, you can use a roasting pan or even a cast-iron skillet—just ensure there’s enough space for everything to roast without crowding. A silicone mat lasts forever and is worth the small investment, but parchment paper works just fine. For budget-friendly options, I’ve found basic aluminum pans work well, but watch the cooking time slightly as heat conduction might differ.

Preparation Method

1. Preheat your oven to 425°F (220°C). This high heat is key for crispiness.
2. Slice the chicken breasts or thighs into even strips, about ½ inch (1.3 cm) thick, so they cook uniformly.
3. Prepare the veggies: Core and slice bell peppers into similar strips; peel and thinly slice the onion.
4. In a large mixing bowl, combine olive oil, garlic powder, chili powder, cumin, paprika, oregano, salt, and black pepper. Whisk together to make a spice marinade.
5. Add the chicken and veggies to the bowl. Toss everything thoroughly until all pieces are evenly coated with the seasoned oil.
6. Spread the chicken and vegetables in a single layer on the prepared baking sheet lined with parchment or a silicone mat. Avoid overcrowding, or else they’ll steam instead of crisp.
7. Roast in the preheated oven for 20-25 minutes, flipping everything halfway through at about 12 minutes. You want the chicken to get a little golden and the edges of the peppers to caramelize nicely.
8. Check doneness: The chicken should reach an internal temperature of 165°F (74°C). The veggies should be tender but still have a slight bite.
9. Remove from oven and squeeze fresh lime juice over the entire sheet for a bright, tangy finish.
10. Garnish with chopped cilantro if using, then serve immediately with warmed tortillas and your favorite fajita fixings like sour cream, guacamole, or shredded cheese.

Pro tip: If your chicken pieces vary in size, remove smaller ones earlier to prevent drying out. And don’t skip the halfway flip—it keeps everything cooking evenly and encourages that crispy texture we all crave.

Cooking Tips & Techniques

Here’s what I’ve learned after making this recipe more times than I can count. First, don’t crowd your sheet pan—overlapping leads to soggy veggies and steamed chicken, which nobody wants. Spread things out to give the heat room to work its magic.

Use a high oven temperature—425°F (220°C)—to get that crispy exterior. Lower temps will cook the food but won’t develop that wonderful caramelization.

Season generously. The spice blend is where the flavor lives. I always taste the seasoning mix beforehand to make sure it’s balanced—sometimes a pinch more salt or chili powder can make all the difference.

Flip halfway through roasting. This simple step keeps the chicken juicy and ensures even cooking on both sides. Trust me, skipping it means unevenly cooked pieces that are less enjoyable.

Lastly, add the lime juice after cooking. It wakes up the whole dish with brightness and balances the smoky spices beautifully.

Variations & Adaptations

You can easily switch up this recipe to suit your taste or dietary needs. Here are a few ways I’ve played around with it:

• Protein Swap: Use thinly sliced steak, shrimp, or tofu instead of chicken. Shrimp only needs about 10 minutes in the oven, so add it later in the cooking time.
• Vegetarian Version: Double the peppers and onions, add sliced mushrooms or zucchini for extra veggies, and serve with black beans or rice.
• Spice Level: Adjust by adding cayenne powder or chipotle chili powder for a smoky heat, or leave it mild for kids.
• Cooking Method: Try cooking in a cast-iron skillet on the stove over medium-high heat for a quicker fajita experience with a great sear.
• Allergen Adaptations: Use gluten-free tortillas or serve over cauliflower rice to keep it grain-free.

One time, I swapped bell peppers for colorful poblano and Anaheim peppers—added a smoky twist that was a hit at a family BBQ. Don’t be afraid to experiment with what’s in your fridge!

Serving & Storage Suggestions

These easy crispy sheet pan chicken fajitas are best served hot right out of the oven, wrapped in warm tortillas with your favorite toppings. I love pairing them with a dollop of sour cream, fresh guacamole, and some tangy salsa. A side of Mexican rice or black beans rounds out the meal perfectly.

If you have leftovers, store them in an airtight container in the fridge for up to 3 days. Reheat gently in a skillet over medium heat to bring back some crispness, or microwave covered for about a minute. The flavors actually deepen overnight, so leftovers can taste even better the next day.

For longer storage, freeze cooked fajita strips in a sealed bag or container for up to 2 months. Thaw overnight in the fridge before reheating.

Nutritional Information & Benefits

This recipe is packed with lean protein from the chicken and vibrant nutrients from the bell peppers and onions, making it a balanced, wholesome meal. One serving (about 1/4 of the recipe without tortillas) typically contains around 300 calories, 35g of protein, 12g of fat, and 10g of carbohydrates.

Bell peppers are rich in vitamin C and antioxidants, supporting immune health, while the spices add flavor without extra calories or sodium. Using olive oil contributes heart-healthy fats. This dish is naturally gluten-free (just watch your tortilla choice) and can be adapted for low-carb or paleo diets easily.

Personally, I appreciate how this fajita recipe fits clean eating goals without sacrificing any of the fun or flavor.

Reheat in a skillet over medium heat to keep the chicken crispy, or microwave covered for about 1-2 minutes for convenience.

Fresh is best for crispiness, but if using frozen, thaw completely and pat dry to avoid sogginess before roasting.

Flour tortillas are classic, but corn tortillas add authentic flavor and are gluten-free. Warm them before serving for softness and pliability.
