I used to think chicken fajitas were just a sizzly show at restaurants until I tried making this marinade at home.
Tender blackened chicken and crisp peppers completely changed my mind. My family actually requests this meal on busy weeknights now. It is a total game changer for easy dinners.

Ingredients for Chicken Fajitas
I always keep these simple staples on hand for a fast weeknight meal. My go to method uses thighs for extra flavor.
- 1.5 lbs chicken thighs (sliced into strips)
- 2 tbsp lime juice
- 1 tbsp soy sauce
- 1 tsp liquid smoke. I recommend this for that grilled flavor
- 2 tbsp cumin
- 2 tsp kosher salt
- 2 tsp chili powder
- 1 tsp smoked paprika
- 1 tsp onion powder
- 0.25 tsp cayenne pepper
- 0.33 cup chopped cilantro
- 4 cloves garlic (minced)
- 2 tbsp vegetable oil
- 2 tbsp butter
- 3 small bell peppers (sliced). My preference is red and yellow for color
- 1 medium onion (sliced)
- 12 6 inch flour tortillas
- 1 cup shredded Monterey Jack cheese. In my experience, melting it in the tortilla is best

Step by Step Instructions
I recommend slicing the chicken against the grain so it stays incredibly tender.
Step 1: Place the sliced chicken in a bowl and toss with lime juice, soy sauce, liquid smoke, cumin, salt, chili powder, smoked paprika, onion powder, cayenne, cilantro, and garlic. Let it sit for 15 minutes.
Step 2: Heat a 12 inch cast iron skillet over medium high heat with vegetable oil. Add chicken in batches, leaving space so it sears properly. Cook for 2 minutes per side until blackened, adding butter halfway through.
Step 3: Remove the chicken and tent with foil. In the same hot skillet, add the sliced peppers and onions with the remaining marinade. Saute for 2 to 3 minutes until crisp tender.
Step 4: Warm tortillas in a clean pan and sprinkle with cheese until melted. Serve the pepper mixture and chicken in the warm tortillas.

Storage and Serving Tips
Store leftover chicken and peppers in an airtight container in the fridge for up to four days. I recommend reheating them in a skillet over medium high heat so the veggies do not get soggy. You can also freeze the cooked meat for up to three months for quick future meals.
FAQs
Can I marinate the chicken for longer than 15 minutes?
Yes, you can marinate the chicken in the fridge for up to 24 hours for even deeper flavor.
Can I use chicken breasts instead of thighs?
Absolutely. Slice the breasts horizontally into thin cutlets so they cook evenly without drying out.
How do I get the chicken blackened without burning it?
Make sure your skillet is very hot before adding the oil and cook the chicken in batches without crowding the pan.
