Ingredients for Chicken Fajita Skillet

For the Skillet

1 lb chicken breast, sliced into thin strips
3 bell peppers (any color), sliced into strips
1 large onion, sliced
2 tablespoons olive oil
1 tablespoon fajita seasoning (or a mix of chili powder, cumin, garlic powder, and paprika)
Salt and pepper to taste
Juice of 1 lime
Fresh cilantro for garnish

Instructions For Chicken Fajita Skillet

1. Season the Chicken and Veggies

In a large bowl, toss the chicken strips, sliced peppers, and onions with olive oil and fajita seasoning until well coated.

2. Heat the Skillet

Heat a large skillet or cast-iron pan over medium-high heat. You want it nice and hot to get a good sear.

3. Cook the Fajita Mix

Add the chicken and vegetable mixture to the skillet. Cook for 8–10 minutes, stirring occasionally, until the chicken is cooked through and the vegetables are tender-crisp with some charred edges.

4. Add Lime Juice

Squeeze fresh lime juice over the skillet and stir to combine. This adds a bright, zesty finish to the dish.

5. Garnish and Serve

Garnish with fresh cilantro and serve immediately with your favorite fajita accompaniments.

Helpful Cooking Tips

Don’t overcrowd the pan; if your skillet is small, cook in two batches to ensure everything gets a nice sear instead of steaming.

Slice the chicken and vegetables into uniform strips for even cooking.

Use a cast-iron skillet if you have one for the best restaurant-style char.

Variations

Make it spicy

Add sliced jalapeños or a pinch of cayenne pepper to the seasoning mix.

Use different protein

Steak or shrimp also work beautifully in this recipe. Adjust cooking times accordingly.

Vegetarian option

Skip the chicken and add more vegetables like mushrooms, zucchini, or black beans.
