The sizzling, the smoke, the dramatic presentation—it all seemed like an over-the-top way to serve what was essentially just grilled chicken and peppers. Then I decided to try making them at home.

Ingredients and Preparation

Main Ingredients

• 1 ½ pounds boneless, skinless chicken thighs (or substitute chicken breast)
• 2 tablespoons lime juice (freshly squeezed)
• 1 tablespoon soy sauce
• 1 teaspoon liquid smoke (optional but recommended for extra depth of flavor)
• 2 tablespoons cumin
• 2 teaspoons kosher salt (use slightly less if using table salt)
• 2 teaspoons chili powder
• 1 teaspoon smoked paprika
• 1 teaspoon onion powder
• ¼ teaspoon cayenne pepper (adjust based on spice preference)
• ⅓ cup fresh cilantro, chopped
• 4 cloves garlic, minced
• 2 tablespoons vegetable oil (for searing)
• 2 tablespoons butter (for extra flavor when cooking the chicken)
• 3 small bell peppers (red, yellow, or orange), sliced
• 1 medium onion, sliced
• 1 teaspoon kosher salt (for the vegetables)
• 12 small flour tortillas (sometimes labeled “fajita size”)
• 1 cup shredded Monterey Jack cheese (optional)

For Garnish

• Sour cream
• Chipotle mayo
• Guacamole
• Lime wedges
• Chopped cilantro

Alternative Ingredients

• Protein Swap – Use beef strips or even shrimp instead of chicken.
• Vegetarian Option – Replace the chicken with portobello mushrooms or firm tofu.
• Cheese Variations – Try Oaxaca, cheddar, or a Mexican cheese blend.
• Gluten-Free Version – Use corn tortillas instead of flour tortillas.

Step-by-Step Instructions

1. Marinate the Chicken

• Slice the chicken thighs into 1-inch wide strips.
• In a medium bowl, combine the lime juice, soy sauce, liquid smoke, cumin, salt, chili powder, smoked paprika, onion powder, cayenne pepper, cilantro, and garlic. Stir well.
• Add the chicken to the marinade and toss until fully coated.
• Let the chicken marinate for at least 15 minutes, but ideally up to 24 hours in the refrigerator for maximum flavor.

2. Prepare the Vegetables

• Slice the bell peppers into thin strips.
• Cut the onion in half, then slice into thin half-moon shapes.
• Set the vegetables aside while the chicken marinates.

3. Sear the Chicken

• Heat a 12-inch cast iron skillet (or your sturdiest pan) over medium-high heat for at least 2 minutes.
• Add 2 tablespoons of vegetable oil and swirl to coat the pan.
• Using tongs, place the chicken strips into the pan, shaking off excess marinade. Do not overcrowd the pan—cook in batches if necessary.
• Sear for about 2 minutes per side until the chicken is browned.
• Add 1 tablespoon of butter to the pan, letting it melt under the chicken for extra richness.
• Flip the chicken and cook until the internal temperature reaches 165°F (or cut a piece open to check that it’s fully white inside).
• Transfer cooked chicken to a plate and cover loosely with foil to keep warm.

4. Cook the Peppers and Onions

• In the same pan, add 2 more tablespoons of oil over medium-high heat.
• Toss in the sliced peppers and onions, sprinkle with 1 teaspoon of salt, and pour in any remaining chicken marinade.
• Cook for 2 to 3 minutes, stirring occasionally. Adjust cooking time depending on your preference—traditional fajitas have slightly firm peppers, but you can cook them softer if you prefer.
• Once done, return the chicken to the pan and toss everything together.

5. Warm the Tortillas

• Heat a clean, dry skillet over medium heat.
• Warm the tortillas one by one, adding a sprinkle of cheese while heating if desired.
• Once warm, keep tortillas wrapped in a clean kitchen towel until ready to serve.

Beginner Tips and Notes

• How to Know if the Chicken is Cooked – The safest way to check is using a meat thermometer. Chicken should reach 165°F internally. If you don’t have one, slice a piece open—there should be no pink inside.
• Avoid Overcrowding the Pan – Crowding the skillet will steam the chicken instead of searing it. Work in batches if needed.
• Control the Spice – The cayenne pepper adds heat, so adjust according to your preference. If you want milder fajitas, reduce or omit it.
• How to Get the Perfect Sear – Ensure the pan is very hot before adding the chicken. This helps achieve a flavorful crust.

Serving Suggestions

• Side Dishes – Serve with Cilantro Lime Rice, black beans, or a fresh green salad.
• Toppings – Add guacamole, salsa, pickled onions, or extra shredded cheese for variety.
• Sauce Pairings – Drizzle with chipotle mayo, sour cream, or a squeeze of lime juice for extra flavor.

Storage and Leftovers

• Refrigeration – Store leftovers in an airtight container in the fridge for up to 3 days.
• Reheating – Warm chicken and vegetables in a skillet over medium heat or microwave in short intervals.
• Freezing – The cooked chicken can be frozen for up to 2 months. Defrost in the fridge overnight before reheating.
