These Chicken Fajita Burgers are packed with bold flavor – juicy chicken, smoky peppers and onions, toasty buns, and a hefty dollop of guac. A burger/fajita mashup you’ll want on repeat!

Just when you thought a burger couldn’t get any better…

The Mash Up You Didn’t Know You Needed!
Okay, kids, this little burger is what happens when a chicken burger meets fajitas and falls in love. A little chicken fajita burger baby, if you will.
We’re talking seasoned chicken patties that you grill (or pan-fry) that you’ll top off with sweet and smoky grilled onions and peppers and our homemade guacamole. It all gets piled on a buttery, toasty bun.
You’ll get the satisfying hand-held mess of a burger, the flavor punch of fajitas, and the kind of goodness that makes people stop mid-bite to say, “Where have these been all my life?”
Similar to my taco sliders, but also totally different, you know?
♥ 3 Reasons You’ll Love This Recipe:
- Weeknight Friendly, Weekend Worthy: The chicken patties are simple to mix and fast to cook. Easy, but impressive, and perfect with a margarita on the rocks.
- A Classic, But Not: This one checks all the boxes without feeling like it’s trying too hard.
- Take Out Vibes, Homemade Goodness: This eats like a $20 burger from the fancy burger joint with the menu that has 30 different burger varieties.
Ingredient Notes:
We’ve broken this up into 2 sections – one for the chicken patties and one for the fajita veggies. You’ll find the full amounts and instructions down in the recipe card.
For the burgers:

Ground Chicken – We go for a ground chicken that’s 92% lean. It’ll cook up nice and moist, so long as you don’t overcook it.
Panko – The panko helps hold the chicken together and adds a light texture to the burger.
Hot Sauce – We mix in our favorite Cholula hot sauce to add a hit of flavor. This doesn’t make the burgers spicy.
Seasoning – You’ll also mix in some garlic powder, onion powder, salt, cumin, and chili powder to add the fajita seasoning flavors to the chicken burger.
For the veggies:

Bell Pepper & Onion – Some thinly sliced bell pepper and onion is pretty much required for any fajita recipe! You can use any color of bell pepper that you like for these. We use sweet onion but other varieties are okay too.
Butter – For sautéing the pepper and onion in the skillet.
Seasoning – We’re adding the same seasoning we used for the chicken burgers to the fajita vegetables.
Step by Step:

Combine all of the chicken burger ingredients in a large bowl and mix well. I like to use my hands to really get it combined.

Form the mixture into 4 round patties. I like to make a slight indention in the center with my thumb to help the burgers hold their shape while grilling.

Place the chicken patties on a hot grill over medium heat and cook for about 5 minutes per side. Top with cheese during the last minute. Use a meat thermometer to be sure it reaches a safe temp of 165 degrees.

Melt some butter in a skillet and add the thinly sliced peppers and onions. Sprinkle with the seasoning and stir to coat. Cook until tender crisp and slightly browned, about 8 minutes.

Toast the burger buns and spread with guacamole, then top with a chicken burger patty and fajita veggies. Serve hot!

My Favorite Thermometer!
I love using this meat thermometer for making sure the meat is fully cooked! Easy for beginners & absolutely worth the low cost.
Helpful Tip!
Storage:
Cooked chicken patties will keep in the fridge for 3 to 4 days.
Sautéed peppers and onions: store separately in the fridge for up to 4 days.
Guacamole is best eaten fresh, but you can press plastic wrap directly on top to help keep it green for 1 to 2 days.
Buns: store at room temp, and toast right before serving for max deliciousness.

Chicken Fajita Burgers
Ingredients
For the burgers:
- 1 pound ground chicken
- 1 large egg
- 1/2 cup panko bread crumbs
- 1 tablespoon Cholula hot sauce or your favorite brand
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon salt
- 1/2 teaspoon cumin
- 1/2 teaspoon chili powder
For the veggies:
- 2 bell peppers your choice of colors
- 1 small sweet onion
- 2 tablespoons butter
- 1/2 teaspoon garlic powder
- 1/2 teaspoon cumin
- 1/2 teaspoon chili powder
- 1/2 teaspoon salt
For making the sandwich:
- 4 sandwich buns buttered and grilled
- 4 slices cheddar cheese
- 1/2 cup homemade guacamole
Instructions
To make the burgers:
- In a large bowl, combine the ground chicken, egg, bread crumbs, hot sauce, garlic powder, onion powder, salt, cumin, and chili powder. Use your hands to combine fully.
- Divide into 4 balls and pat out into patties a bit larger than your buns. Use your thumb to make a light indentation in the center of each patty. This will help to keep the patties from shrinking and puffing up too much as they cook.
- Place the chicken patties on a hot grill or pan over medium heat and cook for 5 minutes. Flip and continue cooking for 5 minutes or until cooked through to an internal temp of 165. Add the cheese over the top during the last minute of cooking.
To make the veggies:
- While the burgers are cooking, heat a large skillet over medium high heat and melt the butter. Thinly slice the peppers and onions and add to the skillet. Sprinkle with the garlic powder, cumin, chili powder, and salt and stir to coat the peppers.
- Cook, stirring often, until peppers and onions are tender crisp and slightly browned, about 8 minutes.
To assemble:
- Spread the toasted buns with guacamole, top with a burger patty, and pile the vegetables over the top. Serve hot.

The best chicken burger I’ve ever had! Unfortunately, I didn’t have avocados or guacamole so used mayo. I also cooked it in a frying pan. It was amazing. Thanks for sharing!
