How to Make the Perfect Chicken Fajita Skillet with Peppers & Onions

This simple process focuses on building layers of flavor by searing the chicken first, then softening the vegetables, and finally combining everything with a quick deglaze. For best results on achieving that perfect sear, see tips on high-heat cooking from Serious Eats.

Step 1: Season and Sear the Chicken Strips

Toss chicken strips with 2 tablespoons of fajita seasoning until fully coated in the spice mix.

Heat 1 tablespoon of olive oil in your large skillet over medium-high heat. Cook the chicken for 5–7 minutes, stirring often, until browned and cooked through.

Step 2: Sauté the Onions and Peppers

Remove the cooked chicken and set it aside. Add the remaining oil to the hot skillet.

Add sliced onions and peppers; sprinkle with the remaining seasoning and sauté for 5–7 minutes until they show slight charring.

Step 3: Deglaze the Skillet for Flavor

Pour in the chicken broth or water into the hot pan immediately.

Use a wooden spoon to scrape up all those flavorful browned bits stuck to the bottom of the skillet.

Step 4: Combine Chicken and Vegetables

Return the seared chicken strips to the skillet with the softening vegetables.

Stir everything together well to coat and allow the mixture to heat through for about one minute.

Step 5: Finishing Touches for Maximum Flavor

Remove the entire skillet from the heat source immediately once everything is hot.

Squeeze the fresh lime juice evenly over the entire mixture and toss gently one final time.
