How to Make Poppy Seed Chicken

Follow these simple steps — the full printable recipe card is usually at the bottom of the original post.

STEP ONE – Preheat oven to 350°F (175°C). Lightly grease a 9×13-inch casserole dish.

STEP TWO – In a large bowl, combine sour cream, condensed cream of chicken soup, poppy seeds and black pepper.

STEP THREE – Stir in the cooked chicken until well coated.

STEP FOUR – Transfer the chicken mixture to the prepared casserole dish and spread evenly.

Variation: For a heartier dish, spread 2–3 cups of cooked rice in the bottom of the casserole dish before adding the chicken mixture.

STEP FIVE – In a small bowl, mix crushed Ritz crackers with melted butter until the crumbs are evenly moistened.

STEP SIX – Sprinkle the buttery cracker mixture evenly over the casserole. Optionally, add an extra teaspoon of poppy seeds on top.

STEP SEVEN – Bake at 350°F for 25–30 minutes, until the filling is hot and bubbly at the edges and the cracker topping is lightly browned. Garnish with chopped parsley if desired and season with additional salt and pepper to taste.

Storage and Reheating

Refrigerator: Cover leftovers tightly or place in an airtight container; refrigerate for 3–4 days. Reheat covered with foil in a 350°F oven for about 20 minutes, or microwave in short intervals until heated through.

Freezing: Baked casserole can be frozen up to three months. Cover tightly with foil or transfer to an airtight container. Thaw overnight in the fridge and bake until warmed through, adding about 15 minutes to the original baking time.

Make-Ahead Tips

Make ahead and refrigerate: Assemble the casserole, cover tightly, and refrigerate for a few days before baking. Add about 10 minutes to the baking time when cooking from chilled.

Make ahead and freeze (unbaked): Prepare the casserole without baking and freeze in an airtight container. Thaw overnight in the refrigerator and bake, adding about 10 extra minutes to the bake time.
