Ingredients

Why this recipe works

The method of layering mashed potatoes, chicken, and béchamel creates a harmonious dish where each component maintains its distinct texture and flavor.

The mashed potato base acts as a sturdy, creamy foundation that soaks up the juices from the chicken and sauce, while the béchamel binds the layers together with its silky richness. Baking the casserole allows the flavors to meld and the top to become golden and bubbly, creating a delightful contrast with the soft interior.

Using a glass baking dish allows you to see the beautiful layers, and it also conducts heat evenly, ensuring the casserole bakes uniformly.

The béchamel sauce, made with butter, flour, and milk, provides a classic, comforting richness that complements the savory chicken and the mild, nutty flavor of kaşar cheese. The final addition of pepper strips not only adds a pop of color but also a slight freshness that cuts through the richness.

Notes and substitutions

Kaşar cheese is a Turkish semi-hard cheese that melts beautifully and has a mild, buttery flavor. If you can't find it, a combination of mozzarella and provolone is an excellent substitute. For the best texture, use starchy potatoes like Russets or Yukon Golds for the mash, as they create a fluffier, creamier base. The chicken can be replaced with turkey or even leftover rotisserie chicken for a quicker version.

Make sure the potatoes are well-drained and hot when mashing to ensure a smooth, lump-free texture. The béchamel sauce should be cooked until it thickens enough to coat the back of a spoon; this ensures it won't be too runny in the casserole. Feel free to adjust the amount of black pepper or add a pinch of cayenne for a little heat. The dish can be assembled ahead and refrigerated, but you may need to increase the baking time.

• kaşar cheese: If kaşar cheese is unavailable, use a combination of mozzarella and provolone for a similar stretchy, melty texture. Or use full-fat mozzarella for a milder flavor.
• chicken breast: Boneless, skinless chicken thighs can be substituted for the breast. They are juicier and more forgiving, but dice them the same size and cook until they reach 165°F (74°C).
• green peppers: Use any color bell pepper you like. Yellow or orange peppers will add a touch of sweetness to the chicken layer.
• all-purpose flour: For a gluten-free béchamel, use a 1:1 gluten-free all-purpose flour blend. The sauce may need a few extra minutes to thicken.
