Prep
1
Shred the cooked chicken into bite-sized pieces using two forks or your hands. If the chicken is dry, drizzle with a splash of water or chicken broth and cover to steam briefly before shredding.
2
Dice the yellow onion finely. Mince the garlic cloves.
3
Grate the cheddar cheese on the medium setting of a box grater. Set aside.

4
In a mixing bowl, combine the shredded chicken, diced onion, minced garlic, grated cheddar, salt, and black pepper. Toss everything together until well distributed.
5
Lay out the tortillas on a clean surface. Divide the chicken and cheese mixture evenly among them, spreading it across one half of each tortilla.
Cook
6
Heat a large frying pan over medium heat. Add 1 tablespoon of sunflower oil and let it shimmer.

8
Flip the quesadilla carefully and cook the other side for another 3–4 minutes until golden and the cheese is fully melted through.
9
Repeat with the remaining tortillas, adding more oil as needed. Keep finished quesadillas warm on a baking sheet in a low oven (80°C / 175°F) while you cook the rest.
Serve
10
Transfer quesadillas to a cutting board. Let them rest for 1 minute, then cut each into three wedges.
11
Serve immediately while the exterior is still crisp. A dollop of yogurt on the side adds brightness — Petra's signature move to wake up yesterday's bird.

Techniques
Safety & Storage
Cooking Temperature
Ensure leftover chicken reaches 74°C/165°F throughout when cooking. The recipe uses day-old chicken so verify proper reheating to eliminate pathogens before combining with cheese and tortillas.
Cross Contamination
Use separate cutting boards for shredding chicken and dicing vegetables/onions. If using the same board, sanitize thoroughly between protein and produce items.
Storage
The leftover chicken must have been stored at 4°C/40°F or below for no more than 3-4 days prior to this recipe. Discard if storage history is unknown or exceeded recommended timeframe.
High Risk Population
This dish contains dairy and repurposed leftover protein. Pregnant individuals, elderly, young children, and immunocompromised persons should verify the chicken's storage date and ensure thorough cooking before consumption.
Shelf Life
Cooked quesadillas should be consumed within 2 hours of preparation. Do not leave at room temperature for more than 2 hours total including serving time.
Handling
When shredding chicken by hand, wash hands thoroughly with soap before and after handling raw protein. Ensure hands are dry before seasoning and combining ingredients.
Equipment Safety
When pressing quesadillas with spatula in hot pan, use heat-resistant utensil. Keep finished items warm at 80°C/175°F minimum in oven - do not hold in danger zone between 4-60°C/40-140°F for extended periods.
Pro Tips
Technique
Press the quesadilla gently but firmly with a spatula while it cooks — this creates even contact with the hot pan and ensures that beautiful golden crust. No pressing means pale, sad spots and cheese that hasn't committed to melting properly.
Flavor Boost
Stir a spoonful of pickle brine or chopped pickled jalapeños into the chicken mixture before assembling. The acid wakes up yesterday's bird in a way that plain salt and pepper simply cannot.
From the chef
Yesterday's roast chicken doesn't want to sit sad in its container waiting to be microwaved into oblivion. No — it wants a second act. This quesadilla is that second act: crispy tortilla, melted cheddar, a little onion and garlic to wake things up, and suddenly I'm not eating leftovers, I'm eating lunch. The yogurt on the side? That's the punctuation mark that makes yesterday's bird feel relevant again.
