Easy Chicken Casserole Recipe Ritz: Buttery Crumb Topping With Creamy Filling

This casserole delivers creamy comfort with a buttery Ritz crumb topping that bakes to golden perfection.

An easy one-dish solution, it combines tender chicken and a velvety filling under that signature crispy layer.

Ingredients for Easy Chicken Casserole Recipe Ritz

Tender chicken, velvety filling, and buttery Ritz crumbs come together for pure comfort.

The chicken is the foundation—opt for boneless, skinless breasts from a trusted butcher or Whole Foods for consistent quality. Perdue or Tyson are reliable supermarket options. For the Ritz crackers, a full sleeve yields just the right amount of crumbs (about 1.5 cups crushed). The butter should be high-quality, like Land O’Lakes, to ensure that rich, golden finish on the topping.

No cream of chicken soup? Cream of mushroom works in a pinch with a slight flavor shift. Greek yogurt can replace the sour cream at a 1:1 ratio for a lighter touch. If cheddar isn’t on hand, Monterey Jack melts beautifully and offers a milder taste. For extra depth, swap dried thyme for fresh (use triple the amount)—just strip the leaves from the stems.

Assemble the casserole up to a day ahead—just refrigerate before baking (add 10 minutes to cook time). Leftovers keep 3-4 days in the fridge or freeze for 2 months. The topping may soften when stored but crisps up if broiled for a minute or two before serving.

Step-by-Step Instructions for Chicken Casserole With Ritz Topping

This method ensures a creamy filling with a perfectly golden, buttery crumb topping every time.

Step 1: Prepare the Chicken and Aromatics

Cut the 1.5 lb Boneless, Skinless Chicken Breasts into bite-sized pieces—this ensures even cooking and easy serving. I prefer uniform, 1-inch cubes for consistent texture throughout the casserole.

Finely dice the 1 whole Yellow Onion and 2 pieces Celery Stalks until you have about 1 cup total. Mince the 2 cloves Garlic Cloves and set all aromatics aside in one bowl. This mise en place approach keeps the cooking process smooth and efficient.

Step 2: Create the Creamy Filling Base

In a large mixing bowl, combine the 2 cans Cream of Chicken Soup, 1 cup Sour Cream, 0.5 cup Chicken Broth, and 0.25 cup Whole Milk. Whisk until completely smooth—you should see no lumps or separation in the mixture.

Add the diced yellow onion, celery stalks, minced garlic cloves, 1 tsp Dried Thyme, 0.5 tsp Salt, and 0.25 tsp Black Pepper. Stir to distribute the seasonings evenly. This base delivers the creamy texture promised while packing in savory depth.

Step 3: Assemble and Top the Casserole

Fold the cubed boneless, skinless chicken breasts and 2 cups Shredded Cheddar Cheese into the creamy mixture. The cheese should be evenly distributed but not fully melted yet—that happens during baking. Transfer everything to a greased 9×13-inch baking dish.

For the topping, crush the 30 pieces Ritz Crackers into coarse crumbs (not powder). Melt the 0.5 cup Unsalted Butter and pour it over the crumbs, tossing to coat evenly. Sprinkle this buttery mixture uniformly over the casserole, pressing down lightly to adhere.

Step 4: Bake to Golden Perfection

Preheat your oven to 375°F. Bake the casserole uncovered for 30-35 minutes. You’re looking for two visual cues: the filling should be bubbling at the edges, and the topping should turn a deep, golden brown.

If the topping browns too quickly, tent loosely with foil for the remaining time. The casserole is done when the internal temperature reaches 165°F and the center no longer jiggles when gently shaken. Let it rest for 5-10 minutes before serving to allow the filling to set.

Make-Ahead Tips for This easy chicken casserole recipe ritz

Assembly Ahead

I always assemble this casserole the night before baking. After topping with the buttery Ritz crumbs, cover tightly with plastic wrap and refrigerate for up to 24 hours. The flavors meld beautifully overnight. 💡

Baking Adjustment

When baking from cold, add 10-15 minutes to the cooking time. Remove the plastic wrap and let it sit at room temperature for 30 minutes before baking to take the chill off.

Topping Protection

To prevent soggy crumbs when storing, keep the buttery Ritz topping separate until ready to bake. Store the crumb mixture in an airtight container at room temperature, then sprinkle just before baking.

Freezer Friendly

This casserole freezes wonderfully for up to 2 months. Assemble completely, wrap tightly in foil, then place in a freezer bag. Thaw overnight in the fridge before baking as usual. ❄️

Crispy Finish

For extra crunch on reheated leftovers, broil for 2-3 minutes until the topping is golden. Watch closely to avoid burning. The butter in the Ritz crumbs helps them re-crisp beautifully.
