Chicken Avocado Quesadilla

My daughter walked into the kitchen one afternoon demanding quesadillas, but with a twist. She wanted something more than cheese, something that felt like dinner but still had that crispy, melty comfort she craved. I scanned the fridge and spotted leftover grilled chicken and a couple of avocados that needed using. What happened next became our new weeknight staple. The combination of smoky seasoned chicken, creamy avocado, and sharp melted cheese tucked into a golden tortilla was so good we made it three times that week.

I started making these on Sunday evenings when I wanted something satisfying but didnt want to spend an hour at the stove. My husband would sit at the counter with a beer, watching me flip the quesadillas until they turned that perfect shade of golden brown. The smell of toasted tortillas mixed with cumin and lime always filled the kitchen, and he would steal little pieces of chicken before I could even assemble them. Now its become our unofficial end of the weekend meal, something we look forward to after a long couple of days.

Ingredients

• Boneless, skinless chicken breasts: I like using medium sized breasts because they cook evenly and slice beautifully, if theyre too thick just pound them gently to an even thickness.
• Olive oil: This helps the spices stick to the chicken and keeps it from drying out on the grill pan.
• Chili powder, cumin, garlic powder: These three spices create that warm, smoky flavor that makes the chicken taste like it came from a taqueria.
• Salt and black pepper: Simple but essential for bringing out all the other flavors in the chicken.
• Ripe avocados: Make sure theyre soft but not mushy, you want them to mash smoothly with just a few chunks for texture.
• Lime juice: Freshly squeezed is best, it brightens the avocado and keeps it from browning too quickly.
• Fresh cilantro: I chop it finely and fold it into the mash for little bursts of herbaceous flavor.
• Flour tortillas: Go for the larger 10 inch size so you have plenty of room to load up the filling without it spilling out.
• Monterey Jack cheese: It melts beautifully and has a mild creamy flavor, but sharp cheddar works great if you want more bite.
• Red onion: Thinly sliced raw onion adds a sweet sharpness that cuts through the richness of the avocado and cheese.
• Cooking spray or olive oil: Just a light coat on the skillet prevents sticking and helps the tortilla crisp up without getting greasy.

Instructions

Get the grill pan ready:

Preheat your grill pan or skillet over medium high heat until a drop of water sizzles on contact. This ensures you get those nice charred marks on the chicken.

Season the chicken:

Toss the chicken breasts in a bowl with olive oil, chili powder, cumin, garlic powder, salt, and black pepper until every surface is coated. The oil helps the spices cling and adds moisture.

Grill the chicken:

Place the seasoned chicken on the hot grill pan and cook for 5 to 6 minutes per side, until the internal temperature reaches 165 degrees and juices run clear. Let it rest for 5 minutes before slicing thinly against the grain.

Make the avocado mash:

In a separate bowl, mash the avocados with lime juice, chopped cilantro, and salt until mostly smooth but with some chunks remaining for texture. Taste and adjust seasoning if needed.

Assemble the quesadillas:

Lay out the tortillas and spread a generous layer of avocado mash on half of each one, then top with sliced chicken, red onion, and shredded cheese. Fold the tortillas in half to enclose the filling.

Cook until golden:

Heat a large skillet over medium heat and lightly coat with cooking spray or olive oil, then cook the quesadillas two at a time for 2 to 3 minutes per side until golden brown and the cheese is fully melted. Press gently with a spatula to help everything meld together.

Slice and serve:

Remove the quesadillas from the skillet and let them cool for a minute or two, then cut each one into wedges with a sharp knife. Serve warm with your favorite toppings on the side.

Save

One night I made these for a group of friends who came over unexpectedly, and I worried they wouldnt be enough. But everyone kept asking for seconds and thirds, scraping up every last bit of avocado mash with the crispy edges of the tortilla. Someone said it tasted like the best parts of a burrito and nachos had a baby, and honestly I couldnt have described it better. That night these quesadillas became more than just a quick dinner, they became something I was proud to share.

Choosing Your Chicken

Fresh chicken breasts work beautifully here, but I wont lie, Ive used rotisserie chicken more times than I can count when Im racing against the clock. If you go that route, just shred or chop the meat and toss it with a little chili powder and cumin to wake up the flavor. You can also use leftover grilled chicken from another meal, which makes this recipe even faster. The key is making sure the chicken is seasoned well, because bland chicken will make the whole quesadilla fall flat no matter how good the avocado mash is.

Getting the Avocado Just Right

I learned the hard way that rock hard avocados will never mash properly, and overripe ones turn into a watery mess that leaks out of the tortilla. You want avocados that yield to gentle pressure but still hold their shape when you cut them open. If theyre not quite ripe, leave them on the counter for a day or two, and if you need to speed things up, tuck them in a paper bag with a banana. The lime juice not only adds brightness but also slows down browning, so your mash stays vibrant green even if you make it a little ahead.

Serving Suggestions and Add Ins

These quesadillas are fantastic on their own, but a dollop of sour cream, a spoonful of salsa, or a drizzle of hot sauce takes them to another level. Sometimes I add diced tomatoes or pickled jalapeños to the avocado mash for extra texture and heat, and my husband loves it when I throw in a handful of black beans for more protein. You can also serve them with a simple side salad or tortilla chips and guacamole if youre feeding a crowd.

• Try adding a sprinkle of cotija cheese on top right before serving for a salty, crumbly finish.
• Swap Monterey Jack for pepper jack if you want a little kick baked right into the quesadilla.
• Leftover quesadillas reheat surprisingly well in a skillet over low heat, just cover with a lid to help the cheese melt again.

Save

This recipe has saved more weeknights than I can count, and it never gets old because you can tweak it based on what you have or what youre craving. I hope it becomes one of those go to meals in your kitchen too, the kind you make without thinking because you know itll always turn out delicious.

Recipe FAQs

→ Can I make this ahead of time?

You can prepare the avocado mash and slice the grilled chicken up to 2 hours ahead, storing them separately in airtight containers. Assemble and cook the quesadillas fresh for best texture and melted cheese.

→ What's the best way to grill the chicken evenly?

Pound the chicken breasts to uniform thickness before seasoning. This ensures even cooking in 5-6 minutes per side. Let the meat rest for 5 minutes after grilling before slicing to retain juices.

→ How do I prevent the tortilla from getting soggy?

Assemble the quesadillas just before cooking and avoid over-spreading the avocado mash. The warm cheese and chicken release moisture, so timing is key. Cook immediately after assembly for crispy results.

→ What cheese works best as a substitute?

Monterey Jack melts beautifully, but sharp cheddar, Oaxaca, or a blend of mozzarella and cheddar also work well. Choose cheeses that melt smoothly for that gooey texture.

→ How can I make this gluten-free?

Use certified gluten-free flour tortillas or corn tortillas as your base. All other ingredients, including the chicken seasoning and avocado mash, are naturally gluten-free. Always verify ingredient labels.

→ Can I add other fillings?

Absolutely. Diced tomatoes, jalapeños, black beans, corn, or caramelized onions enhance the flavor profile. Layer additions between the avocado mash and cheese to keep the tortilla from getting soggy.
