Ingredients

  • Boneless skinless chicken thighs chopped: They stay juicy and soak up fajita flavors so well Look for chicken with a healthy pink color and little excess fat
  • Green and red bell peppers sliced: Add crispness and color Choose peppers that feel firm and glossy
  • Sweet onion sliced: Brings mellow sweetness Slice it evenly for even cooking A medium sized sweet onion works best
  • Taco seasoning: Gives that iconic fajita kick A homemade or store bought blend works
  • Large flour tortillas: The foundation for a sturdy golden quesadilla Use fresh soft tortillas for easy folding
  • Shredded Mexican cheese: Melts beautifully and adds flavor Use a blend with Monterey Jack and cheddar for the best texture
  • Ripe avocados: The base for rich creamy guacamole They should yield just a bit with gentle pressure
  • Onion for guacamole diced: Adds zing For guac opt for a white onion if possible
  • Cilantro chopped: Brightens flavors Look for fresh crisp leaves
  • Jalapeño peppers diced: Bring just the right amount of heat Choose shiny firm peppers and remove seeds for mild guacamole
  • Medium tomato diced: Introduces freshness and a touch of tang Roma tomatoes work well here
  • Juice of two limes: For zing and to keep guacamole vibrant Use fresh limes and roll before juicing for extra juice
  • Salt and pepper to taste: Essential for seasoning everything Use flaky salt if available for guacamole

Step-by-Step Instructions

Prep and Season the Chicken:
Chop the chicken thighs into bite sized pieces Pat them dry so they sear well Toss with taco seasoning until evenly coated This seasoning creates a savory crust on the chicken
Cook the Chicken:
Heat a splash of oil in a large skillet over medium high heat Add the chicken spaced out so it browns not steams Sear for about 8 to 10 minutes turning occasionally until golden and cooked through Remove chicken from pan
Sauté the Vegetables:
In the same skillet add the sliced peppers and onions Stir frequently and cook over medium heat for about 6 to 7 minutes They should be just tender and lightly caramelized not mushy You want the veggies to still have a bit of bite
Combine Chicken and Vegetables:
Return the cooked chicken to the skillet and toss everything together Let them mingle over the heat for another minute or two so flavors combine Allow to cool slightly so the cheese does not melt too soon when assembling
Make the Guacamole:
Cut avocados open and remove the pits Scoop flesh into a bowl and mash until mostly smooth Add diced onion cilantro jalapeño tomato lime juice salt and pepper Mix just until combined so some chunks remain Taste and adjust seasoning as you like
Assemble Quesadillas:
Lay a tortilla flat Sprinkle a generous handful of cheese over half the tortilla Top with chicken and vegetable mixture then another layer of cheese Fold the tortilla over pressing gently Repeat with remaining tortillas and filling
Cook the Quesadillas:
Heat a clean skillet or griddle over medium heat Place folded quesadillas in batches and cook 2 to 3 minutes per side Press gently with a spatula to help the cheese melt evenly When each side is golden brown and crisp remove to a cutting board
Serve and Enjoy:
Let quesadillas rest one or two minutes for the cheese to set Cut each into wedges Serve warm with the fresh guacamole on the side or spooned right on top

My favorite part of this recipe is the sizzle and aroma of onions and peppers hitting the hot pan My kids always rush to the kitchen as soon as the smell fills the house Watching them gather around for their favorite dinner is the best reward every time

Storage Tips

Leftover quesadillas store well in an airtight container for up to three days in the fridge To reheat warm them on a skillet over low heat to restore crispness Guacamole is best fresh but you can press plastic wrap directly onto its surface and chill for one day to minimize browning

Ingredient Substitutions

You can use chicken breast in place of thighs but watch for dryness For a vegetarian twist swap in sautéed mushrooms and black beans If you do not like heat in your guacamole skip the jalapeños and add more tomato or extra cilantro
