Ingredients and Substitutions
I love these fajita chicken sandwiches as much as I love my Cajun chicken sandwich. It’s quick, easy, and tastes so good. The combination of chicken and cheese is heavenly. With the same ingredients, you can make both chicken fajita wraps and chicken fajita rice, except for a few additional ingredients. Here’s why you will love this chicken fajita sandwich recipe.
For the Chicken Marinade
- Chicken - I have used boneless skinless chicken breast. You can also use boneless skinless chicken thighs.
- Olive Oil - Olive oil works great. You can substitute it with any cooking oil with a neutral flavor and high smoke point.
- Lemon juice - I have used fresh lemon juice. Fresh lime juice also works great. Substitute with rice vinegar.
For the Fajita Seasoning
You can use store-bought Fajita seasoning or make it easily at home. All you need is to combine paprika, cayenne pepper (or any spicy chili powder), onion powder, garlic powder, cumin powder, oregano, salt, and black pepper powder. Your homemade fajita seasoning is ready.
For the Fajita Vegetables
You will need bell peppers & onions. I have used red bell pepper, green bell pepper, and yellow bell pepper. You can use any color of bell pepper you have.
For the Sandwiches
- Sandwich Bread/ hamburger buns - I have used sliced sandwich bread to assemble the sandwich. But you can also use burger buns or any of your favorite bread. Go for lettuce leaves and make healthy chicken fajita wraps, tortillas, or tacos.
- Tomato sauce - I have used hot and sweet tomato sauce here. It gives a sweet and spicy flavor. You can also use sriracha or any hot sauce here. Or you can use tomato ketchup.
- Butter (For toasting the sandwich bread) - You can also use oil.
- Cheese - I have used both processed cheese slices and mozzarella. You can use any cheese of your choice like Cheddar, Monterey Jack Cheese, or any Mexican Cheese. Do not skip it. This truly adds a delicious flavor to the sandwich. This fajita sandwich is incomplete without the cheese.

How to Make Chicken Fajita Sandwiches (Step-by-Step with Photos)
Preparations
- Prepare the Fajita Seasoning: In a small bowl, combine all the ingredients mentioned under fajita seasoning. Remove 1 teaspoon seasoning from it and set it aside. We will use that later.
- Marinate the Chicken: Slice the chicken breast in half. You will get 4 slices from 2 chicken breasts. Set it aside. In a big bowl, combine the rest of the fajita seasoning, oil, and lemon juice. Marinate the chicken breast with it for at least 4 hours. Cover and keep it in the refrigerator.
Making the Chicken Fajita Sandwich
- Cook the chicken: Heat 2 teaspoons of oil in a pan over medium-high heat. When the pan is hot, place the chicken breasts on it. Fry until char marks appear on both sides. Remove it on a plate. Let it cool down for 10 minutes. Slice the chicken breasts into thin strips.
- Cook the Fajita Vegetables: Scrape off the burnt bits on the pan or you can wipe them with a kitchen tissue. To the same pan, add 1 teaspoon of oil. Add onions and bell pepper. Stir-fry for 2 minutes. Add the reserved fajita seasoning. Cook it for 1 more minute or until vegetables are soft. Add 2 tablespoons tomato sauce (optional). Add it as it gives some moisture to the veggies. Combine. Remove from heat.
- To assemble the sandwich: Place a sandwich bread slice. Top it with the cheese (processed cheese slice and mozzarella cheese), fajita vegetables, and chicken.
- Cover it with another bread slice. Apply butter on the top slice. Place the butter side of the sandwich in a heated pan. Cook on low heat for a minute or until crisp and golden. Apply butter on the other side of the sandwich. Flip it. Cook for a minute and remove.
- Chicken Fajita Sandwich is ready to serve. Slice it in half and serve hot with tomato sauce or hot sauce, sour cream, salsa, or Guacamole.
Tips for Making the Best Chicken Fajita Sandwich
- Slice the chicken breast in half to ensure even cooking.
- Pan-fry the vegetables separately. Make sure the vegetables are charred but not overcooked.
- Marinate the chicken for 4 hours or overnight for the best flavors. It makes the chicken soft, juicy, and flavorful. However, if short of time, you can marinate it for 30 minutes. Transfer the marinated chicken to an airtight container and keep it in the refrigerator.
- Grill the chicken on high heat. The pan should be very hot. When you put the marinated chicken in the heated pan, you should hear a sizzling sound. This will seal the outer surface of the chicken & lock the moisture inside. Cook the chicken until char marks appear on it. It will result in the best juicy and moist chicken that is crispy outside with a nice smoky flavor.

Notes
- Slice the chicken breast in half. This helps the chicken breast to cook evenly.
- Marinate the chicken for 4 hours or overnight. Marinating the chicken for longer hours makes it soft and juicy. This will also increase the flavor of the chicken. However, if short of time, you can marinate for 1 hour.
- To marinate, transfer the chicken to an airtight container, and keep it in the refrigerator.
- Grill the chicken on high heat - The pan should be very hot. When you put the marinated chicken on it, you should hear a sizzling sound. This will seal the outer surface of the chicken & lock the moisture inside. It will result in the best juicy and moist chicken that is crispy outside.
- Cook the chicken - Make sure to cook the chicken until it is cooked through. You can make a small cut in the middle to check that it is no longer pink in the middle. It should be white or opaque in the middle.
- Cook the chicken until char marks appear on it. It will give a nice smoky flavor to the chicken.
- Give at least 10 minutes of resting time to the chicken, once it is cooked. Then slice it.
- Pan-fry the vegetable separately. Make sure the vegetables are charred but not overcooked.
- Tomato sauce is not a part of the chicken fajita. The addition of tomato sauce to veggies makes them soft and moist. I love to add them to make sandwiches.
- Adjust the quantity of fajita seasoning as per your taste.
