Lime Sheet-Pan Chicken Fajitas with Quick Avocado Guacamole

Sheet pan chicken fajitas are the ideal weeknight dinner: everything roasts together on one pan, developing charred, smoky flavor, then gets stuffed into warm tortillas with plenty of lime, cheese and creamy toppings.

We make fajitas often because they’re easy to prep ahead, quick to assemble and almost always provide leftovers. Marinating the chicken and vegetables a day ahead is a great time-saver and intensifies the flavor, but this sheet pan method is especially simple and reliable, even without long marination.

This version is bright with lime and balanced by a touch of honey and smoky spices. I often reach for these flavors when I want something fresh and zesty instead of richer autumnal dishes. The combination of peppers, onions and chicken roasted until caramelized makes a classic, crowd-pleasing filling.

This method works brilliantly

fajita marinade

Start by coating the peppers and onions in half the marinade and roast them first so they get nicely caramelized. Then move them to one side of the pan and add the marinated chicken to roast the rest of the way. This simple sequencing ensures each component cooks to the right doneness without overcooking or crowding the pan.

The marinade is lime-forward with olive oil, lime zest and juice, honey for balance, and a warming blend of cumin, chili powder and smoked paprika. Garlic, salt and black pepper finish it off. Tossing half the marinade with the veggies and using the rest on the chicken keeps flavors consistent and bright.

Top the finished fajitas with crumbled cotija cheese and chopped cilantro for freshness. Avocado slices or a quick guacamole add creaminess; a spoonful of sour cream (or even a little mayo) and a generous squeeze of lime complete the plate. Serve with warmed tortillas and crunchy chips for scooping.

My quick guacamole is a pared-down mix of mashed avocado, lime juice, diced onion, cilantro and salt and pepper—nothing fancy, just bright and creamy to complement the fajitas.

These fajitas are a go-to for busy nights: minimal hands-on time, big flavor and easy cleanup. They’re adaptable too—use chicken thighs for more richness, swap in different colored peppers, or serve the mixture over rice or salad for a fajita bowl.

These sheet pan chicken fajitas are an easy weeknight meal, bright with lime and loaded with roasted peppers and onions.

Ingredients

  • 1/3 cup olive oil
  • 1/4 cup freshly squeezed lime juice
  • 2 tablespoons fresh lime zest
  • 1 tablespoon honey
  • 1 teaspoon cumin
  • 1 teaspoon chili powder
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon salt
  • 1/2 teaspoon black pepper
  • 2 garlic cloves, minced
  • 2 bell peppers (mix of red, orange or yellow), sliced
  • 1 sweet onion, sliced
  • 1 pound chicken breasts, cut into 1-inch pieces
  • 1/4 cup chopped fresh cilantro, plus more for serving
  • lime wedges, warm tortillas, cotija cheese and sour cream for serving

Quick Guacamole

  • 2 avocados
  • 1 to 2 limes, juiced
  • 2 tablespoons diced onion
  • 1/4 cup chopped cilantro
  • salt and pepper to taste

Instructions

  • Note: if desired, you can marinate the peppers and chicken separately up to 24 hours ahead.
  • Preheat the oven to 425°F. Prepare a baking sheet by lining with foil or spraying with nonstick spray.
  • Whisk together the olive oil, lime juice, lime zest, honey, cumin, chili powder, smoked paprika, salt, pepper and minced garlic.
  • Place the sliced peppers and onions on the baking sheet. Add half the marinade and toss until evenly coated. Roast for 15 to 20 minutes, tossing once or twice, until caramelized.
  • Meanwhile, place the chicken pieces in a bowl and pour the remaining marinade over them. Let sit until the peppers are roasted.
  • When the peppers are done, push them to one side of the pan and spread the chicken in a single layer on the empty side. Roast for about 15 minutes more, or until an instant-read thermometer registers 165°F for chicken pieces.
  • Assemble fajitas by filling warm tortillas with roasted peppers and onions and the cooked chicken. Finish with a squeeze of lime, crumbled cotija, sour cream or guacamole and chopped cilantro.

Quick Guacamole

  • Mash the avocados and stir in lime juice, diced onion, chopped cilantro and salt and pepper to taste. Serve immediately on the fajitas or on the side.
