Chicken Fajita Burgers
A simple chicken fajita marinade turns plain-old chicken into juicy and tender chicken burgers that are full of flavor. Top them with peppers and onions for a fun twist on chicken fajitas!

Fajitas are summer thing for me because what’s better than a quick-to-make dinner along with chips, salsa, and guacamole when it’s hot outside? But instead serving up the chicken fajitas on a sizzling hot platter we’re going burger-style because burgers are a summer thing, too, and I always love a good mash-up.
And as much as I love the sweet peppers piled on the burger with a bit of melty cheese it’s the tender, juicy chicken breasts that are really the star of the show. So this post is more about the chicken fajita marinade – a simple marinade that turns a boring old piece of chicken into something a little more special.

Ingredients
- Boneless, skinless chicken breasts: Pound them out to an even thickness so they cook evenly.
- Chili seasoning or taco seasoning: There’s one tablespoon in the marinade and a teaspoon for the peppers and onions.
- Lime juice and zest
- Honey
- Olive oil
- Kosher salt
- Fresh cilantro
- Bell peppers
- Red onion
- Sliced Monterrey jack cheese or pepper jack cheese
- Burger buns
- Toppings: Guacamole and sour cream

How to Make Fajita Burgers
☑️ Marinate the Chicken
Combine one tablespoon of the seasoning, lime juice, honey, olive oil, salt, and cilantro in a large resealable bag. Place the chicken breasts in the marinade and seal the bag. Marinate the chicken for at least 30 minutes but no longer than an hour in the refrigerator.
☑️ Cook the Peppers and Onions
Heat the olive oil in a large skillet over medium heat. Add the sliced onions and peppers and stir to coat them in the oil. Add the chili seasoning and lime juice and cook the peppers and onions until they start to soften, about five to eight minutes. Transfer the cooked peppers and onions to a plate.
☑️ Cook the Chicken
Remove the chicken from the marinade and allow the excess to drip off. Cook the chicken breasts in the same pan for about 10 minutes or until the chicken is cooked through (the internal temperature should be 165°F).

☑️ Assemble the Burgers
Top the burgers, while they’re in the pan, with the peppers and onions. Add a piece of cheese on top. Turn the heat off and cover the pan with a lid.

Ingredients
For the Chicken
For the Burgers
- 1 tablespoon olive oil
- 2 large bell peppers sliced
- 1/2 medium red onion sliced
- 1 teaspoon chili seasoning or taco seasoning
- Juice of 1/2 a lime
- 4 slices Monterrey jack cheese
- 4 hamburger buns
- Optional toppings: sour cream and guacamole
Instructions
- Combine all of the ingredients for the marinade in a large resealable bag. Place the chicken breasts in the marinade and seal the bag. Sort of smoosh the chicken around in the marinade so all of the pieces are coated. Marinate the chicken for at least 30 minutes but no longer than an hour in the refrigerator.
- Heat one tablespoon of olive oil in a large skillet over medium heat. Add the sliced onions and peppers and stir to coat them in the oil. Add the chili seasoning and lime juice and cook the peppers and onions until they start to soften, about five to ten minutes. Transfer the cooked peppers and onions to a plate.
- Remove the chicken from the marinade and pat it dry with paper towels. In the same skillet, cook the chicken breasts on one side for about four to five minutes or until it turns golden brown. Turn the chicken and cook it on the other side for another four to five minutes or until the chicken is cooked through (the internal temperature should be 165°F).
- Turn the heat off and place the cooked peppers and onions on top of the chicken in the skillet. Add the cheese and cover the skillet with a lid until the cheese has melted.
- Place the pepper and cheese topped chicken breasts on the hamburger buns. Top with sour cream and guacamole, if using.

Happy summer cooking!

I made this but didn’t do burger buns just the chicken, peppers and cheese and it was delicious. Reheated well the next day, too.
So glad you liked it!
