Spice up your weeknight dinner with these juicy chicken fajita burgers. Ground chicken gets a tasty fajita seasoning and tops are loaded with sweet cooked peppers and onions, melty Monterey Jack, plus smooth guacamole. They're quick to whip up and bring a fresh twist to a classic meal that's super satisfying.

I first made these when I wanted fajitas but something easy to hold. Everyone loved them so much they’re now a go-to dinner at our house.

What You Need

  • Fresh lime juice: adds zing to both guacamole and the chicken mix
  • Avocado: mashed for creamy guacamole that cools down the spices
  • Monterey Jack cheese: melts nicely and adds rich flavor without stealing the show
  • Red bell pepper and yellow onion: sautéed for sweet, soft crunch and caramelized flavor
  • Chili powder, cumin, oregano, and garlic powder: create the true taste of fajitas
  • Ground chicken: lean and juicy, great for holding all those spices
  • Fresh cilantro: gives a fresh bright flavor that lifts the whole dish
  • Buns: pick ones that are soft but strong enough to hold everything together

How To Make It

Make The Guacamole First
Use a fork to mash avocado until it's almost smooth but still a bit chunky. Mix in chopped cilantro, diced onion, garlic powder, lime juice, salt, and pepper. Taste and add more lime or salt to get it just right. This guac adds smooth brightness that balances the spices.
Mix The Chicken
Combine chili powder, cumin, oregano, garlic powder, cilantro, lime juice, salt, and pepper in a large bowl. Add the chicken and gently mix with your hands until everything is combined. Shape into four equal patties. Lay them on parchment paper so they don't stick.
Cook Peppers And Onions
Heat olive oil in a skillet over medium-high. Toss in thin sliced red bell pepper and yellow onion. Stir occasionally for 6 to 8 minutes until they soften and start to brown a little. Take them out and set aside.
Cook The Patties
Turn heat down to medium, add more olive oil if pan looks dry. Add chicken patties and let cook without moving for 4 to 5 minutes. Flip carefully so they don’t break. Put a slice of Monterey Jack on each patty and keep cooking until the patties reach 165°F inside and cheese melts.
Put The Burgers Together
If you like, toast or warm the buns. Place a patty on the bottom bun, top with the cooked peppers and onions, then spoon the guacamole on. Finish with the top bun and serve right away for the best taste and texture.

I love how fresh lime juice lifts every bite, from the chicken mix to the guacamole. The first time I served these was out on the porch with a cold drink. That citrus hit was the perfect match for smoky spices and it stuck with me—simple, happy moments.

Storage Tips

Keep leftover cooked patties in an airtight container in the fridge for up to three days. Reheat gently in a pan or microwave. Add a splash of water and cover to keep them moist. Store guacamole separately because it goes brown quickly. Before serving, stir in some fresh lime juice to brighten it up again.

Swap Ideas

You can use ground turkey or lean pork instead of chicken with the same spice mix. Switch Monterey Jack for Pepper Jack to add some heat. If you can't find fresh cilantro, flat leaf parsley works but tastes different. Store-bought guacamole is fine if it has simple fresh ingredients and no extras.

Serving Tips

Try these with crunchy sweet potato fries or a simple green salad for a well-rounded meal. Add salsa or pickled jalapeños for extra zing. You can even wrap the burgers in big lettuce leaves for a low-carb meal.

Put ground chicken, spices, lime juice, cilantro, salt, and pepper in a big bowl. Use your hands to mix gently till just combined. Cut into four pieces and form into patties. Keep them on parchment paper so they don't stick.
