👨🍳 How to Make Chicken Fajitas Step-by-Step
Step 1: Marinate the Chicken
In a zip-top bag or shallow bowl, mix together all the marinade ingredients. Add the chicken strips and toss to coat. Refrigerate for 30–60 minutes to let the flavors soak in.
Step 2: Sear the Chicken
Heat 2 tsp olive oil in a large skillet over medium-high heat. Remove the chicken from the marinade (discard the rest) and add to the pan. Cook for 4 minutes, flipping once the underside is browned. It should be about halfway cooked.
Step 3: Add Veggies
Add the sliced onions and bell peppers. Continue cooking for 5–8 minutes, stirring occasionally, until the vegetables are softened and the chicken is fully cooked (internal temp should hit 165°F / 74°C).
Step 4: Assemble & Serve
Warm the tortillas and pile on the fajita mix. Add your favorite toppings and dig in! 🌮

- Double the batch – Leftovers are great in salads, bowls, wraps, or quesadillas
