My aunt Helen made this for every church potluck from 1975 until she passed, and people still ask me for the recipe. Only 4 ingredients!

This oven baked 4-ingredient poppy seed chicken is pure Midwestern church-basement nostalgia. My Aunt Helen brought a pan of this to nearly every potluck from the mid-70s on, and there was never a spoonful left. It’s creamy, comforting, and wonderfully simple—just chicken, a pantry-friendly sauce, and that unmistakable buttery Ritz and poppy seed topping. This is the kind of recipe you make when you want something cozy, crowd-pleasing, and dependable, without pulling out half the pantry.

Serve this casserole hot, straight from the oven, with something that can soak up the creamy sauce. Steamed white rice or buttered egg noodles are classic partners, and a simple green vegetable—like roasted broccoli, sautéed green beans, or a crisp lettuce salad—keeps the plate balanced. A pan of soft dinner rolls or crusty bread is also nice for scooping up the extra sauce, and if you’re feeding a crowd, a fruit salad or coleslaw rounds out that familiar potluck-style spread.

Servings: 6

4 cups cooked shredded chicken (from about 1 rotisserie chicken or 1 1/2 pounds cooked chicken)

Preheat your oven to 350°F (175°C). Lightly grease a 9x13-inch or similar-sized oval baking dish so the casserole releases easily after baking.

In a large mixing bowl, combine the cooked shredded chicken and the condensed cream of chicken soup. Stir until the chicken is evenly coated and the mixture is creamy and uniform. Taste and, if desired, season very lightly with salt and pepper, keeping in mind the soup and crackers are already salty.

Transfer the creamy chicken mixture to the prepared baking dish and spread it into an even layer, smoothing the top with a spatula or the back of a spoon.

Place the Ritz crackers in a large zip-top bag and crush them with your hands or a rolling pin until you have coarse, pea-sized crumbs—some texture is good. In a medium bowl, stir together the crushed crackers and the melted butter with poppy seeds until all the crumbs are evenly moistened and speckled.

Sprinkle the buttery Ritz and poppy seed mixture evenly over the chicken layer, covering it from edge to edge. Gently pat the crumbs so they adhere but don’t pack them down too firmly.

Bake the casserole, uncovered, in the preheated oven for 25–30 minutes, or until the filling is hot and bubbly around the edges and the cracker topping is golden brown.

Remove from the oven and let the casserole rest for about 5–10 minutes before serving. This short rest helps the creamy interior thicken slightly so it scoops more neatly. Serve warm, spooning generous portions to show off the creamy chicken beneath the crisp topping.

If you grew up on church suppers, you’ve probably seen a few versions of this casserole, and it’s very forgiving. You can use any cooked chicken you like: leftover roast chicken, poached chicken breasts, or a store-bought rotisserie bird all work. White meat tends to shred more neatly, but a mix of white and dark meat adds more flavor and moisture. If you prefer a slightly looser sauce, stir in a splash or two of milk, chicken broth, or even sour cream with the condensed soup, but keep in mind that this will make the filling a bit softer. For a lighter touch, you can substitute reduced-fat condensed cream of chicken soup and use slightly fewer crackers; just know that the original version is unapologetically rich. If you don’t have Ritz, any buttery round cracker will do, though the flavor will shift slightly. You can also scale this down by half and bake it in an 8x8-inch dish for a smaller household. Food safety tips: Always start with fully cooked chicken; this recipe is designed to heat and meld flavors, not to cook raw poultry. If you cook the chicken yourself, cool it quickly and refrigerate within 2 hours, then shred and use within 3–4 days, or freeze for longer storage. When baking the casserole, make sure the center is piping hot; an internal temperature of 165°F (74°C) ensures it’s safe. Leftovers should be cooled promptly, refrigerated in a covered container, and eaten within 3–4 days. Reheat portions until steaming hot all the way through, either in the oven or microwave, and avoid reheating more than once for best quality and safety.
