What Ingredients You Will Need

This recipe uses simple, fresh ingredients that pack a big flavor punch. Many of these are pantry staples, and you can easily swap or adjust them to suit your preferences.

Chicken: 1 lb (450g) boneless, skinless chicken breasts or thighs (thighs are juicier, but both work).
Bell Peppers: 2 large, assorted colors (red, yellow, or green), sliced into strips.
Onion: 1 large red onion, sliced into thin wedges.
Olive Oil: 2 tbsp (for grilling and marinade).
Lime Juice: Juice of 2 limes (freshly squeezed for best flavor).
Garlic: 3 cloves, minced.
Spices: 1 tsp chili powder, 1 tsp ground cumin, 1 tsp smoked paprika, ½ tsp onion powder, ½ tsp garlic powder, ¼ tsp cayenne pepper (optional for heat), salt and pepper to taste.
Cilantro: Fresh, chopped (optional for garnish).
Tortillas: 6-8 flour or corn tortillas, warmed.
Toppings: Sour cream, guacamole, shredded cheese, salsa, or any other favorites.

If you’re missing an ingredient, don’t worry! Swap lime juice for lemon, or use yellow onions instead of red. You can even toss in mushrooms or zucchini to mix up the veggies. This recipe is super forgiving.

Equipment Needed

Grill or Grill Pan: For that perfect smoky flavor and gorgeous char marks.
Tongs: Essential for flipping and handling the chicken and veggies.
Mixing Bowls: For whisking the marinade and tossing the veggies.
Knife & Cutting Board: To slice the chicken, peppers, and onion.
Ziplock Bag or Container: To marinate the chicken effectively.
Cast Iron Skillet: An alternative to grill veggies indoors.

Don’t have a grill? No problem! A stovetop grill pan or even a regular frying pan works just fine. For extra convenience, you can use pre-sliced veggies from the store and save time on prep!

Preparation Method

Make the Marinade: In a mixing bowl, whisk together olive oil, lime juice, garlic, chili powder, cumin, smoked paprika, onion powder, garlic powder, cayenne (if using), and a pinch of salt and pepper.
Marinate the Chicken: Place chicken in a ziplock bag or container, pour the marinade over, and ensure it’s evenly coated. Seal and refrigerate for at least 30 minutes (up to 4 hours for deeper flavor).
Prepare the Grill: Preheat your grill to medium-high heat (around 375°F or 190°C). Lightly oil the grates to prevent sticking.
Slice the Veggies: While the chicken marinates, slice the bell peppers and onion into strips.
Grill the Chicken: Remove chicken from the marinade and place it on the grill. Cook for 6-8 minutes per side or until the internal temperature reaches 165°F (74°C). Set aside to rest for 5 minutes before slicing.
Grill the Veggies: Toss the sliced veggies with a drizzle of olive oil and a pinch of salt. Grill them directly on the grates or use a grill basket, turning occasionally, until they’re softened and lightly charred (about 5-7 minutes).
Warm the Tortillas: Wrap tortillas in foil and place them on the grill for 1-2 minutes, or heat them individually in a skillet.
Assemble the Fajitas: Slice the chicken into thin strips. Fill each tortilla with chicken, veggies, and your favorite toppings. Garnish with cilantro and serve with lime wedges.

Pro tip: Don’t overcrowd the grill! Cooking the chicken and veggies in batches ensures even grilling and perfect char marks.

Cooking Tips & Techniques

Don’t Skip the Marinade: The lime juice tenderizes the chicken while the spices infuse it with bold flavor.
Use a Meat Thermometer: Ensure the chicken reaches 165°F (74°C) for food safety and optimal juiciness.
Rest the Chicken: Letting it rest after grilling locks in the juices and makes slicing easier.
Char the Veggies: Aim for lightly blackened edges for that smoky fajita flavor.
Multitask: While the chicken rests, grill your veggies and warm up the tortillas—it’s a time-saver!

If your grill runs hot, keep an eye on the veggies—they can char quickly! And don’t forget to taste and adjust the seasoning before serving.

Variations & Adaptations

Vegetarian Option: Swap chicken for grilled portobello mushrooms or tofu.
Low-Carb Version: Serve the chicken and veggies over lettuce wraps or cauliflower rice instead of tortillas.
Seasonal Twist: Add zucchini or asparagus during summer, or butternut squash in the fall.
Spice Level: Adjust cayenne to your liking—or add jalapeños to the mix for extra heat.
Cheese Lover’s Dream: Sprinkle shredded pepper jack or queso fresco over the fajitas before serving.

Last week, I tried adding pineapple chunks to the mix—it added a delightful sweetness! Feel free to experiment and make this recipe your own.

Serving & Storage Suggestions

Serve these fajitas hot, right off the grill. Pair them with sides like Mexican rice, refried beans, or a simple green salad. A cold drink like margaritas or a refreshing lime soda complements the meal perfectly.

Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, simply warm the chicken and veggies in a skillet over medium heat or in the microwave. If freezing, store the chicken and veggies separately from the tortillas and consume within 2 months.

The flavors deepen overnight, making leftovers even more delicious! Wrap them in fresh tortillas and enjoy a quick lunch the next day.

Nutritional Information & Benefits
