Creamy Ritz Chicken Casserole
Creamy Ritz chicken casserole is the kind of weeknight dish that tastes like you spent way longer on it than you did. Tender shredded chicken, a tangy sour cream sauce, and a buttery, crunchy cracker topping come together in under 10 minutes of hands-on time.

If you keep a rotisserie chicken in the fridge and a sleeve of Ritz in the pantry, you are already halfway to a dinner that will disappear fast. This is the version I turn to when I want zero-fuss comfort food.
Why This Casserole Is a Keeper
The sauce is rich and tangy, with sour cream adding a little brightness that cuts through the richness. The Ritz topping stays crisp in the oven, giving every bite that irresistible buttered cracker crunch.
I love that it tastes like something simmered for hours, but it uses just a handful of pantry staples. Leftovers are somehow even better the next day, as the flavors settle in.
Ingredients

- 4 cups cooked shredded chicken: from a rotisserie or 4 poached breasts
- 1 can (10.5 oz) cream of chicken soup
- 1 cup sour cream
- 1/2 cup whole milk
- 1 tsp garlic powder
- 1/2 tsp onion powder
- salt and black pepper, to taste
- 2 cups crushed Ritz crackers: about 1 sleeve, crushed but still with some texture
- 1/4 cup melted unsalted butter
- 1 cup shredded sharp cheddar cheese: optional, but makes it extra creamy
Substitutions and Swaps
- Use cooked turkey: for a post-holiday twist.
- Greek yogurt: can replace the sour cream for a tangier, lighter option.
- Add a diced jalapeño: to the filling for a little heat.
- Swap in cream of mushroom soup: if you prefer.

How to Make Creamy Ritz Chicken Casserole
Step 1: Whisk the Creamy Sauce

Preheat your oven to 350°F (180°C). In a large bowl, whisk together the 1 can cream of chicken soup, 1 cup sour cream, 1/2 cup milk, 1 tsp garlic powder, and 1/2 tsp onion powder until smooth. Season with a small pinch of salt and a few cracks of black pepper.
The mixture will be thick but spreadable. Give it a taste and adjust the salt, keeping in mind the crackers and soup already bring plenty of saltiness.
Step 2: Fold in the Chicken and Cheese

Add the 4 cups shredded chicken and the 1 cup shredded cheddar to the bowl. Fold it all together with a rubber spatula until the chicken is evenly coated. The mixture should be creamy and scoopable, not dry.
If it seems too stiff, stir in a splash more milk. You want it loose enough to spread easily but not runny.
Step 3: Crush the Ritz Topping

Place the 2 cups Ritz crackers (roughly 1 sleeve) in a zip-top bag and crush them with a rolling pin. Stop when you have a mix of fine crumbs and some larger pieces about the size of a pea. Pour the crumbs into a small bowl, drizzle the 1/4 cup melted butter over top, and stir with a fork until all the crumbs are evenly moistened and clumpy.
This uneven texture is what keeps the topping crispy rather than sandy. The larger bits stay crunchy even after baking.
Step 4: Assemble the Casserole

Lightly grease a 9×13-inch baking dish. Spread the chicken mixture into an even layer, then scatter the buttery cracker crumbs evenly over the surface. Make sure the crumbs cover all the way to the edges so every bite gets that crunch.
For extra golden spots, you can dot a few thin pats of cold butter across the topping before baking.
Step 5: Bake and Serve Hot

Bake the casserole for 25 to 30 minutes, until the topping is deep golden brown and the filling is bubbling around the edges. Let it rest for 5 minutes on a cooling rack before scooping onto plates.
The casserole will be piping hot, so a short rest helps it set up just enough to serve neatly. Scoop right from the dish and enjoy the contrast of creamy filling and crisp crumbs.
Tips for the Best Casserole
- Use rotisserie chicken for the fastest prep and an extra boost of savory flavor.
- Do not crush the crackers into a uniform powder. Chunky, uneven crumbs stay crispier.
- For a thicker sauce, reduce the milk to 1/4 cup.
- Let the casserole sit for 5 minutes after baking so the filling firms up slightly and serves without running.
Storing Leftovers
- Refrigerate: Store in an airtight container in the fridge for up to 4 days.
- Reheating: Reheat individual portions in the microwave, or cover the whole dish with foil and warm in a 325°F oven for about 15 minutes.
What to Serve with Ritz Chicken Casserole
A simple green salad with a lemon vinaigrette cuts through the richness beautifully. Steamed green beans or roasted broccoli also work well. For something heartier, try serving it over egg noodles to catch every last bit of sauce.
Frequently Asked Questions
Can I use fresh uncooked chicken instead of rotisserie?
Yes. Poach 3 to 4 boneless, skinless chicken breasts in simmering water for about 15 minutes, then shred them once cool enough to handle.
Can I make this casserole ahead of time?
Absolutely. Assemble everything except the cracker topping, cover, and refrigerate for up to 24 hours. Just before baking, add the topping and bake as directed.
Can I freeze this casserole?
Yes. Freeze the unbaked casserole without the topping for up to 3 months. Thaw overnight in the fridge, add the topping, and bake.
