Creamy Curry Chicken Casserole with Mozzarella

A comforting one-dish meal combining tender chicken breast with a mild, creamy curry sauce enriched by sour cream and mayo, topped with melted mozzarella. The spice rub adds depth while the curry powder provides warm, aromatic flavor without heat. Serve hot straight from the oven for an easy weeknight dinner that feels restaurant-quality. This version streamlines prep by pan-searing rather than fully cooking the chicken, reducing overall time while maintaining moisture and tenderness.

Instructions

  1. 1

    Preheat oven to 375°F and spray baking dish with non-stick spray.

  2. 2

    Combine ground thyme, poultry seasoning, salt, and black pepper into a rub.

  3. 3

    Trim chicken breasts and coat evenly with spice rub.

  4. 4

    Heat olive oil in a large frying pan over medium-high heat and brown chicken on both sides until golden but not cooked through.

  5. 5

    While chicken browns, whisk together mayo, sour cream, cream of chicken soup, curry powder, and lemon juice until smooth.

  6. 6

    Cut each browned chicken breast into three thick strips.

  7. 7

    Arrange chicken strips in the prepared casserole dish in a single crosswise layer.

  8. 8

    Pour sauce evenly over chicken strips.

  9. 9

    Sprinkle grated mozzarella cheese across the top.

  11. 11

    Let rest 2-3 minutes before serving.

Tips

Tip 1

Brown chicken only until golden on both sides; it finishes cooking in the oven and stays more tender than pre-cooked chicken.

Tip 2

Use fresh-squeezed lemon juice for brightness that cuts through the richness of mayo and sour cream.

Tip 3

Curry powder strength varies widely by brand; start with 1 tablespoon and taste the raw sauce, adjusting before baking if needed.

Good to Know

Storage

Cover and refrigerate up to 3 days. Reheat covered in 190C oven for 15-20 minutes until warmed through.

Make Ahead

Assemble casserole through cheese topping up to 8 hours ahead; refrigerate covered. Bake from cold, adding 5-10 minutes to cook time.

Serve With

Serve directly from baking dish while hot. Pairs well with steamed rice, roasted vegetables, or a simple green salad to balance richness.

Common Mistakes

Watch

Cook chicken completely before baking to avoid undercooked chicken in final dish.

Watch

Underbrown chicken to prevent dry, tough texture after baking.

Watch

Stir sauce ingredients thoroughly to avoid lumps from cream of chicken soup.

Watch

FAQ

Can I make this with chicken thighs instead of breast?

Yes. Use the same weight of boneless thighs; they release more fat and stay juicier. Brown the same way and extend baking by 3-5 minutes since thighs are thicker. Flavor deepens with thigh meat.

What if my curry powder is very spicy?

Start with 1.5 teaspoons instead of 1 tablespoon, taste the raw sauce, and adjust before baking. Some brands labeled curry are mild while others are hot; testing prevents overseasoning.

How long does this keep and can I freeze it?

Refrigerate covered for 3 days. Freezing is possible but the sauce texture becomes slightly separated on thawing; best frozen before baking. Thaw overnight and bake as directed.
