Ingredients You Need

Chicken and Marinade

1 ½ pounds boneless skinless chicken breasts, thinly sliced into strips
- You can use chicken thighs if you prefer richer flavor and more forgiveness with cooking time.
3 tablespoons neutral oil (avocado, canola, or light olive oil)
2 tablespoons fresh lime juice (about 1 large lime)
1 tablespoon orange juice (optional, adds a hint of sweetness)
3 cloves garlic, minced
1 ½ teaspoons chili powder
1 teaspoon ground cumin
1 teaspoon smoked paprika
½ teaspoon dried oregano
½ teaspoon onion powder
½ to 1 teaspoon kosher salt, to taste
¼ teaspoon black pepper
¼ to ½ teaspoon cayenne pepper, to taste (optional for heat)

You can swap individual spices with a good quality fajita or taco seasoning blend if you want a pantry shortcut. In that case, use about 2 ½ tablespoons seasoning plus 2 tablespoons oil and lime juice.

Vegetables

1 large yellow onion, thinly sliced
1 red bell pepper, thinly sliced
1 green bell pepper, thinly sliced
1 yellow or orange bell pepper, thinly sliced
1 tablespoon oil
Pinch of salt and pepper

Use any mix of bell peppers you have on hand. Frozen sliced peppers and onions work in a pinch; just cook them a bit longer to drive off extra moisture.

Tortillas and Toppings

8 to 10 small flour tortillas or corn tortillas
- Choose flour tortillas for soft, flexible fajitas or corn tortillas for a gluten friendly option.
1 cup shredded cheese (cheddar, Monterey Jack, or a Mexican blend)
1 avocado, sliced or mashed
½ cup sour cream or plain Greek yogurt
½ cup salsa or pico de gallo
Fresh cilantro, chopped
Extra lime wedges

You can use store brand tortillas and cheese without any problem; the seasoning and fresh lime carry most of the flavor.

Equipment List

Large cast iron skillet or heavy stainless steel skillet
Cutting board and sharp knife
Mixing bowl or zip top bag for marinating
Tongs or spatula
Measuring spoons and cups

How to Make How to Make Chicken Fajitas

Step 1: Prep the Chicken and Marinade

Slice the chicken into thin strips about ½ inch wide. Place the strips in a bowl or zip top bag.

Add oil, lime juice, orange juice, garlic, chili powder, cumin, smoked paprika, oregano, onion powder, salt, pepper, and cayenne. Toss everything until the chicken coats evenly, then chill for 20 to 30 minutes while you prep the vegetables.

Step 2: Slice the Vegetables

Peel and slice the onion into thin half moons. Core and seed the bell peppers, then slice them into thin strips.

Keep the slices similar in size so they cook at the same rate. Set the vegetables aside near the stove so you can move quickly once the skillet heats.

Step 3: Cook the Vegetables

Heat 1 tablespoon oil in a large skillet over medium high heat until it shimmers. Add the sliced onions and peppers in an even layer.

Sprinkle with a pinch of salt and pepper. Cook 5 to 7 minutes, stirring occasionally, until the vegetables soften and develop a few charred spots while they still keep some bite, then transfer them to a plate.

Step 4: Cook the Chicken

Return the skillet to medium high heat and add a drizzle of oil if the pan looks dry. Add the marinated chicken in a single layer, working in batches if needed so you avoid crowding the pan.

Let the chicken cook undisturbed for 2 to 3 minutes so it browns, then stir and cook another 3 to 4 minutes until the strips cook through and no pink remains. If the pan starts to smoke too much, lower the heat slightly.

Step 5: Combine Chicken and Vegetables

Add the cooked peppers and onions back into the skillet with the chicken. Toss everything together so the vegetables pick up the flavorful juices and browned bits from the pan.

Squeeze a little extra lime juice over the top and taste a piece of chicken. Adjust salt or lime if needed so the flavors pop.

Step 6: Warm the Tortillas

While the chicken and veggies stay on low heat, warm your tortillas. Heat a dry skillet over medium heat and warm each tortilla for about 20 to 30 seconds per side until soft and pliable.

You can also wrap a stack of tortillas in a slightly damp paper towel and microwave for 30 to 45 seconds. Keep them wrapped in a clean kitchen towel so they stay warm at the table.

Step 7: Build and Serve

Set out the skillet of chicken fajitas, warm tortillas, and all your toppings. Fill each tortilla with a few strips of chicken, some peppers and onions, and your favorite toppings like cheese, avocado, salsa, and sour cream.

Finish with a squeeze of lime and a sprinkle of cilantro. Expect a little mess and enjoy every saucy bite.

Recipe Variations

Gluten friendly: Use corn tortillas and confirm your spice blend and salsa use gluten free ingredients.
Dairy free: Skip cheese and sour cream or use plant based versions and extra avocado for creaminess.
Vegan: Swap chicken with sliced portobello mushrooms, extra peppers, and black beans or tofu strips marinated in the same seasoning.
Low carb: Serve the fajita chicken and veggies over lettuce, cauliflower rice, or zucchini noodles instead of tortillas.
Extra protein: Add black beans or pinto beans to the skillet in the last few minutes of cooking.
Extra veggies: Toss in sliced mushrooms, zucchini, or cherry tomatoes near the end so they stay bright and tender.

Ways to Serve

Classic style in warm tortillas with cheese, salsa, avocado, and lime.
Fajita bowls over rice, quinoa, or cauliflower rice with beans and shredded lettuce.
Stuffed into crisp lettuce cups with salsa and a little Greek yogurt.
Over baked potatoes with cheese, salsa, and cilantro.

Storage Success

Let the chicken and vegetables cool to room temperature, then store them together in an airtight container in the fridge for up to 4 days. Reheat in a skillet over medium heat with a splash of water or lime juice so the chicken stays juicy. You can also reheat in the microwave in short bursts and stir between each round. Store tortillas at room temperature in their package, and slice fresh toppings like avocado right before serving.
