Poppyseed Chicken Casserole

• The filling starts with cooked chicken, so prep stays focused on mixing rather than raw-meat timing. A rotisserie chicken gives this casserole a practical head start and keeps the ingredient list short.
• Crushed buttery crackers provide contrast against the soft filling. Dividing them between the mixture and the top gives each scoop some texture, while melted butter helps the upper layer brown evenly.
• Six portions make this a sensible dinner for a family table. It also works for planned lunches, because the square-cut leftovers reheat without needing a separate sauce or fresh garnish.

• 3 cups cooked rotisserie chicken, diced or lightly torn (420 g)
• 1 (10.5-ounce) can condensed cream of chicken soup (298 g)
• 1 cup full-fat sour cream (240 g)
• 1/3 cup chicken broth (80 g)
• 1 teaspoon garlic powder (3 g)
• 1/2 teaspoon black pepper (1 g)
• 2 cups buttery round crackers, crushed, divided (170 g)
• 6 tablespoons unsalted butter, melted (85 g)
• 1 tablespoon poppy seeds (9 g)
• 2 tablespoons chopped parsley, optional (8 g)

Ingredient notes

• Cooked rotisserie chicken keeps the casserole quick. Use three cups from breast, thigh, or a mixture, cut into bite-size pieces. Dark meat is especially useful if the chicken was frozen before assembling, because it stays more forgiving in a creamy bake.
• Condensed cream of chicken soup supplies body and seasoning in one can. Cream of mushroom works when that is already open, although its earthier flavor changes the familiar profile. Choose regular sour cream, not a pourable substitute, for a thicker filling.
• Chicken broth loosens the soup and sour cream enough for an even coating. Store-bought broth is completely fine here. Use low-sodium broth if that suits your pantry, then taste the mixed filling before adding any salt.
• Buttery round crackers are the classic topping choice. Crush them into irregular pieces rather than fine dust, which gives the finished casserole more distinct crunch. Keep half separate until the end, so the top remains dry before baking.
• Poppy seeds are small but noticeable, so measure them instead of scattering by guesswork. Parsley is optional and mainly adds color. Skip it if you are keeping the ingredient list lean, or use sliced scallions after baking.

1. 1Heat the oven

   Set an oven rack in the center position and heat the oven to 350°F. Lightly butter a 9-by-13-inch baking dish, including the corners. Set the dish on a rimmed sheet pan if you prefer easier handling when the hot casserole comes out of the oven.

2. 2Mix the creamy filling

   In a large bowl, stir together condensed soup, sour cream, chicken broth, garlic powder, and black pepper until no streaks remain. The mixture should look thick but easily spoonable. If it seems stiff, add another tablespoon of broth rather than adding extra sour cream.

   

3. 3Fold in chicken and crackers

   Add the cooked chicken, poppy seeds, and half of the crushed crackers to the bowl. Fold gently until every piece is coated. Avoid vigorous stirring, which can break the chicken into threads and turn the crackers soft before they reach the oven.

   

4. 4Fill the baking dish

   Scrape the mixture into the prepared dish and spread it into an even layer with a spatula. Press gently into the corners without packing it down. An even surface helps the center heat at the same pace as the edges and makes cleaner portions later.

5. 5Add the buttered topping

   Combine the remaining crushed crackers with melted butter in a small bowl. Toss until the pieces look lightly coated, then scatter them evenly over the filling. Leave the topping loose instead of pressing it down, which gives it more room to crisp and brown.

6. 6Bake and rest

   Bake for 25 to 30 minutes, until the topping is golden and the filling bubbles around the edges. Let the dish stand for 10 minutes before scooping. This short rest firms the creamy layer, prevents messy servings, and gives the cracker crust time to settle.

• Dice or lightly tear the chicken into similar-size pieces before mixing. Large chunks can leave some servings sparse, while very fine pieces disappear into the sauce and lose their distinct texture.
• Use a 9-by-13-inch dish for the stated bake time. A smaller, deeper dish needs longer in the oven, and a larger dish can dry the filling before the cracker topping colors.
• Crush crackers in a zip-top bag with a rolling pin. Stop when you have both small crumbs and pea-size pieces. That mix creates a sturdier, more interesting top layer.
• If the topping browns before the filling bubbles, loosely lay foil over the dish. Remove it for the final few minutes if the crackers need more color.

Serve generous squares with a crisp green salad dressed simply with lemon and oil. Steamed green beans, roasted carrots, or buttered peas fit the creamy filling well. For a larger table, add warm rolls and let the casserole carry the main job. A spoonful of cranberry sauce also works nicely beside it. Plan on six servings from this pan, with smaller portions if there are several side dishes.
