Ingredients
- Sour cream: this provides tanginess and creaminess that forms the base of our sauce
- Cream of chicken soup: creates a rich consistency and depth of flavor without extra work
- Worcestershire sauce: just a teaspoon adds that umami depth that makes the sauce irresistible
- Lemon juice: brightens all the flavors and balances the richness of the cream components
- Cooked chicken breasts: choose plump ones and cook them just until done to keep them juicy
- Ritz crackers: these buttery crackers create the perfect golden topping that makes this dish special
- Butter: use unsalted so you can control the seasoning level of your dish
- Poppy seeds: they add a subtle nutty flavor and beautiful contrast against the golden topping
Step-by-Step Instructions
- Prepare the baking dish:
- Preheat your oven to exactly 350°F and lightly grease your 8×8 inch baking dish. Using a proper size dish ensures the perfect ratio of topping to filling. Make sure to coat all sides to prevent sticking.
- Create the cream sauce:
- In a medium bowl combine the sour cream and cream of chicken soup until completely smooth. Whisk in the Worcestershire sauce and lemon juice until fully incorporated. This sauce should be thick but pourable with no lumps.
- Arrange the chicken:
- Spread your cooked chopped chicken pieces evenly across the bottom of your prepared baking dish. Make sure the chicken pieces are bite sized but not too small. The chicken forms the substantial base of this dish.
- Pour the sauce:
- Evenly pour your cream sauce mixture over the chicken layer making sure to cover all the chicken pieces. Use a spatula to spread it to the edges if needed. Every bite should have sauce.
- Prepare the topping:
- In a separate bowl gently combine the crushed Ritz crackers with melted butter until every crumb is coated but not soggy. The butter should be warm but not hot enough to make the crackers mushy.
- Add the finishing touches:
- Sprinkle the buttery cracker mixture evenly over the sauce layer then distribute the poppy seeds across the top. Press very lightly to help the topping adhere to the sauce below.
- Bake to perfection:
- Place the casserole in the preheated oven and bake for exactly 20 minutes or until you see the edges bubbling and the topping has turned a beautiful golden brown. Let stand for 5 minutes before serving.

The poppy seeds are more than just a pretty topping in this recipe. They add a subtle nutty flavor and satisfying crunch that elevates this simple casserole to something special. My grandmother always insisted on adding them generously saying that the tiny seeds were what transformed an ordinary chicken dish into something company worthy.
Make Ahead and Storage
This casserole is perfect for planning ahead. You can assemble it completely up to 24 hours before baking just cover tightly with plastic wrap and refrigerate. When ready to cook remove from the refrigerator 30 minutes before baking to take the chill off. Leftovers will keep beautifully in the refrigerator for up to 3 days. Reheat individual portions in the microwave for 1 to 2 minutes or larger amounts in a 325°F oven until warmed through about 15 minutes.
Delicious Variations
While the classic recipe is perfect as is there are several delicious ways to make it your own. Try adding a cup of steamed broccoli florets or sautéed mushrooms to the chicken layer for extra vegetables. For a cheesy version mix in 1 cup of shredded cheddar or Gruyère into the sauce. You can also add herbs like thyme or tarragon to the cream mixture for an aromatic twist. Some families even layer cooked egg noodles on the bottom for a complete one dish meal.

Serving Suggestions
This casserole stands beautifully on its own but pairs wonderfully with simple sides. Serve alongside steamed green beans or a crisp green salad dressed with vinaigrette to balance the richness. For heartier appetites offer a side of white or brown rice to soak up the delicious sauce. Warm dinner rolls or crusty bread make excellent accompaniments for gathering every last bit of that creamy goodness from your plate.
The History Behind the Dish

This recipe represents the best of that era's ingenuity combining simple ingredients into something greater than the sum of its parts. The dish has remained popular through generations because it delivers reliable comfort while allowing for personal touches and adaptations based on family preferences.
Recipe FAQs
- → Can I prepare this casserole ahead of time?
Yes! You can assemble the casserole up to 24 hours in advance and refrigerate it covered. Just add the cracker topping right before baking to keep it crispy. You may need to add 5-10 minutes to the baking time if cooking directly from the refrigerator.
- → What can I serve with poppy seed chicken casserole?
This versatile dish pairs wonderfully with steamed rice, egg noodles, or mashed potatoes. For vegetables, consider roasted broccoli, green beans, or a simple side salad to balance the creamy richness of the casserole.
- → Can I freeze this casserole?
Yes, this casserole freezes well. Prepare through step 3, but don't add the cracker topping. Cover tightly and freeze for up to 3 months. When ready to cook, thaw overnight in the refrigerator, add the cracker topping, and bake as directed, adding about 10-15 extra minutes.
- → How do I know when the casserole is done?
The casserole is done when the topping is golden brown and the sauce is bubbling around the edges, typically after about 20 minutes at 350°F. Since the chicken is pre-cooked, you're primarily heating everything through and melding the flavors.
- → Can I use other crackers besides Ritz?
Absolutely! While Ritz crackers provide that classic buttery flavor, you can substitute other crackers like saltines, butter crackers, or even crushed corn flakes. For a healthier option, try whole grain crackers or a mixture of panko breadcrumbs and grated parmesan.
- → Why add poppy seeds to the casserole?
Poppy seeds add a pleasant visual contrast, subtle nutty flavor, and slight crunch to the casserole. They're a traditional ingredient that complements the creamy sauce and buttery topping, but the dish would still be delicious without them if you prefer to omit.
