Make Chicken Fajita Sandwiches: A Simple Method

Step 1: Marinate the Chicken
Start by seasoning the chicken thighs with taco seasoning. You can use store-bought or make your own blend. Ensure the chicken is well-coated, then allow it to sit for at least 15 minutes to absorb the flavors.
Step 2: Cook the Chicken
In a large skillet or grill pan, heat 1 tablespoon of vegetable oil over medium-high heat. Add the marinated chicken thighs and cook for about 5-7 minutes on each side or until they are fully cooked and reach an internal temperature of 165°F (75°C). Once done, remove from heat and let them rest for a few minutes before slicing.
Step 3: Sauté the Vegetables
In the same skillet, add another tablespoon of vegetable oil if needed, and toss in the sliced onions and bell peppers. Season with 1/2 teaspoon of taco seasoning, salt, and pepper. Sauté for about 5-7 minutes until the vegetables are tender and slightly caramelized.
Step 4: Prepare the Chipotle Sauce
In a mixing bowl, combine the mayonnaise, pressed garlic, lemon or lime juice, and chipotle chili powder. Mix until smooth, and adjust the seasoning with salt and additional chipotle powder if desired.
Step 5: Assemble the Sandwiches
Slice your rolls and layer the sliced chicken, sautéed vegetables, and a slice of cheese on each roll. If you prefer melted cheese, you can pop the assembled sandwiches under the broiler for a minute or two until the cheese is bubbly.
Step 6: Serve and Enjoy
Spread the chipotle sauce generously on the inside of the top half of the roll, place it on the sandwich, and serve with your favorite sides. These Chicken Fajita Sandwiches are perfect for sharing, so don’t forget to invite your friends or family to enjoy!
Spring–Summer–Fall–Winter Ideas

- In spring, add fresh avocado slices for a creamy texture.
- During summer, serve with a side of corn salad for a refreshing contrast.
- In fall, try adding roasted butternut squash for a sweet twist.
- In winter, pair with a warm soup, like a spiced tomato bisque.
Little Things that Matter
Don’t rush the marinating process. The longer the chicken sits with the seasoning, the more flavorful it will be. Also, feel free to customize your sandwich with additional toppings like jalapeños, fresh cilantro, or a squeeze of lime for an extra zing. The key to delicious Chicken Fajita Sandwiches lies in the balance of flavors, so don’t skimp on the seasoning!
Meal Prep & Storage Notes
If you’re looking to meal prep, the chicken and sautĂ©ed vegetables can be stored in an airtight container in the refrigerator for up to 4 days. Reheat them in a skillet or microwave before assembling your sandwiches. For longer storage, consider freezing the cooked chicken and veggies, which can last up to 3 months. Just be sure to thaw them in the fridge before reheating.
Helpful Q&A
Can I use chicken breast instead of thighs?
Absolutely! Chicken breast is a leaner option, but it may dry out if overcooked. Keep an eye on the cooking time to ensure they remain juicy.
What can I substitute for mayonnaise?
If you’re looking for a lighter option, Greek yogurt works well as a substitute for mayonnaise in the chipotle sauce. It will give you the creaminess without all the calories!
Are these sandwiches spicy?
The spice level can be adjusted based on your preferences. If you prefer a milder flavor, reduce the amount of chipotle chili powder or use a less spicy cheese. Conversely, if you love heat, add more seasoning or fresh jalapeños.
Can I make this recipe vegetarian?
Yes! Substitute the chicken with grilled portobello mushrooms or marinated tofu for a delicious vegetarian option. Just follow the same cooking method for the vegetables and sauce.
