Chicken and Spinach Quesadilla

The skillet was still warm from breakfast when I decided to throw together whatever was left in the fridge. A bit of cooked chicken, some spinach that needed using, and a block of mozzarella that had been staring at me all week. I folded it all into a tortilla, pressed it down with my spatula, and watched the cheese start to ooze out the sides. That first bite, with its crispy edges and melty center, turned leftovers into something I now crave on purpose.

I made these for my sister one evening when she stopped by unannounced. She was between meetings and starving, and I was out of impressive ingredients. I sliced the quesadilla into wedges, set them on a plate with some salsa, and she ate every piece standing at the counter. She still texts me asking how I made them taste so good, and I still tell her it was just Tuesday night and whatever I had on hand.

Ingredients

• Cooked chicken breast, shredded or diced: Leftover rotisserie chicken works beautifully here and saves you from cooking meat from scratch, just shred it with two forks.
• Fresh spinach, roughly chopped: It wilts down fast, so dont worry if the pile looks huge at first, it shrinks to almost nothing once it hits the heat.
• Shredded mozzarella cheese: Mozzarella melts smooth and stretchy without getting greasy, but feel free to mix in cheddar or Monterey Jack if you want more sharpness.
• Olive oil: Use this for sauteing the filling and greasing the skillet, it adds a subtle richness that butter alone doesnt quite give.
• Small onion, finely chopped: Optional but worth it, the onion adds a little sweetness and depth once it softens in the pan.
• Garlic, minced: Just one clove is enough to make the whole filling smell incredible without overpowering the other flavors.
• Salt, black pepper, and smoked paprika: These three seasonings bring the filling to life, the paprika adds a hint of smokiness that makes it taste more complex than it actually is.
• Large flour tortillas: Go for the 10 inch size so you have enough room to load in the filling and still fold it neatly in half.
• Butter or additional olive oil: This is what makes the outside golden and crispy, dont skip it or youll end up with a pale, sad quesadilla.

Instructions

Saute the aromatics:

Heat 1 tablespoon olive oil in a large skillet over medium heat, then add the onion and garlic if youre using them. Let them sizzle for about 2 minutes until they smell sweet and toasty.

Wilt the spinach and combine the filling:

Toss in the spinach and stir it around until it collapses into a soft heap, about 2 to 3 minutes. Add the chicken, salt, pepper, and smoked paprika, stirring everything together until its warmed through, then take the skillet off the heat.

Assemble the quesadillas:

Wipe the skillet clean with a paper towel. Lay a tortilla flat, sprinkle a quarter of the cheese over one half, then pile on a quarter of the chicken spinach mixture and fold the tortilla in half. Repeat with the remaining tortillas.

Grill until golden:

Heat half a tablespoon of butter or olive oil in the skillet over medium heat. Slide in a quesadilla and let it cook for 2 to 3 minutes per side, pressing gently with your spatula, until both sides are golden and the cheese has melted into gooey submission.

Slice and serve:

Let the quesadilla cool for a minute so you dont burn your mouth, then cut it into wedges with a sharp knife. Serve warm with whatever toppings make you happy.

One night I made a double batch and packed the extras in foil for my neighbor who had just had a baby. She told me later that she reheated one at midnight and ate it over the sink, still half asleep. It became our little tradition, I'd make quesadillas whenever life got messy, and shed text me a photo of her late night snack. Food doesnt have to be fancy to feel like care.

Choosing Your Cheese

Mozzarella is my go to because it melts so smoothly and doesnt overpower the chicken and spinach. But Ive also used Monterey Jack when I wanted something creamier, and sharp cheddar when I was in the mood for a bolder bite. A Mexican blend works well too, especially if you like a little kick. The key is to use something that melts easily and doesnt get oily or rubbery under heat.

Making It Your Own

This recipe is forgiving enough to handle substitutions without falling apart. If you dont have chicken, try black beans or sauteed mushrooms for a vegetarian version. Swap the spinach for kale or even roasted red peppers if thats what you have. I once added a spoonful of cream cheese to the filling and it made everything richer and creamier. Trust your instincts and use what sounds good to you.

Serving and Storing

These quesadillas are best eaten right after theyre made, while the outside is still crispy and the cheese is molten. But if you have leftovers, wrap them in foil and store them in the fridge for up to two days. Reheat them in a dry skillet over medium low heat to bring back some of that crispness, microwaving will make them soggy. Serve with salsa, sour cream, or guacamole on the side, or just eat them plain if youre too hungry to wait.

• Pair them with a simple side salad or tortilla chips and salsa for a more complete meal.
• If youre feeding a crowd, keep finished quesadillas warm in a low oven while you cook the rest.
• Slice them into smaller pieces and serve as an appetizer at parties, they disappear fast.

This quesadilla has become my answer to whats for dinner when I dont have an answer. Its quick, satisfying, and somehow always tastes better than the sum of its parts.
