Ingredients for Southern Poppy Seed Chicken

For the chicken:

• 4 cups cooked shredded chicken (about 1 rotisserie chicken)
• 1 can (10.5 oz) condensed cream of chicken soup
• 1 cup sour cream
• 2 teaspoons poppy seeds
• 1/2 teaspoon garlic powder
• 1/2 teaspoon onion powder
• 1/4 teaspoon black pepper
• 1/4 cup chicken broth or milk (optional, to loosen)

For the topping:

• 1 sleeve buttery round crackers (about 1 1/4 cups crushed), such as Ritz
• 1/2 cup (1 stick) unsalted butter, melted
• 1 tablespoon poppy seeds

Ingredient Notes

• Crackers: Buttery round crackers give the classic flavor. Crush them to coarse crumbs.
• Poppy seeds: They add a nutty flavor and the dish’s signature look.
• Sour cream: It adds tang and makes the sauce creamy. Greek yogurt works in a pinch.

How to Make Poppy Seed Chicken Casserole

Step 1: Prep

Heat the oven to 350 degrees F and grease a 7×11 inch or 9×9 inch baking dish.

Step 2: Mix the filling

In a large bowl, stir together the chicken, soup, sour cream, 2 teaspoons poppy seeds, garlic powder, onion powder, and pepper until evenly coated. Add a splash of broth if it feels stiff.

Step 3: Spread

Spread the mixture into the baking dish in an even layer.

Step 4: Make the topping

Mix the crushed crackers, melted butter, and 1 tablespoon poppy seeds until the crumbs are evenly coated. Sprinkle over the chicken.

Step 5: Bake

Bake for 25 to 30 minutes, until the sauce is bubbling around the edges, the topping is golden brown, and the casserole is hot in the center (165°F / 74°C).

Step 6: Rest and serve

Rest for 5 minutes, then serve over egg noodles or rice.

Why This Poppy Seed Chicken Casserole Recipe Works

Because the chicken is already cooked, the casserole only needs to heat through, so the chicken stays tender instead of drying out. The sour cream and soup make a thick, creamy sauce that does not split in the oven. And the butter-soaked crackers crisp into a golden crust that gives the creamy filling a satisfying crunch.

My Best Tips for Southern Poppy Seed Chicken

• Use rotisserie chicken for the juiciest result.
• Do not skip the butter on the crackers. It makes the crust crisp and golden.
• Crush the crackers coarsely. Fine crumbs turn pasty.
• Do not overbake. Once the topping is golden and the edges bubble, it is done.
• Serve it hot over noodles or rice for the best texture.

Poppy Seed Chicken Casserole Variations

With broccoli

Fold in 2 cups of steamed broccoli florets for a chicken broccoli version.

Without canned soup

Use a homemade sauce of 2 tablespoons butter, 2 tablespoons flour, and 1 1/4 cups chicken broth, simmered until thick.

Lighter version

Use Greek yogurt in place of sour cream and a reduced fat soup.

Crispy panko topping

Swap half the crackers for panko for an extra crunchy crust.

How to Store and Reheat

Refrigerate leftovers within 2 hours and use within 3 to 4 days. Reheat to 165°F (74°C), as Ohio State University Extension recommends for leftovers. The topping softens, so crisp it in a 350°F oven for 10 minutes. Freeze the unbaked casserole, without the topping, for up to 2 months.

Make ahead

Assemble the filling up to 24 hours ahead and refrigerate. Add the buttered topping just before baking.
