This hearty Chicken Bacon Crunch Casserole has become my go-to recipe whenever I need a crowd-pleasing comfort food that delivers maximum satisfaction with minimal effort. The combination of tender chicken, smoky bacon and that irresistible crunchy topping creates a dish that disappears fast at any gathering.
I first made this casserole when hosting an impromptu dinner for neighbors during a power outage. We had to use my gas stove, and this simple dish brought so much comfort during a stressful evening that it's now requested at nearly every gathering.
Ingredients
- Cooked chicken breast: The foundation of our casserole that soaks up all the creamy goodness. Rotisserie chicken works perfectly here for convenience and flavor
- Bacon: Adds that irresistible smoky flavor that elevates the entire dish. Look for thick-cut bacon for the best texture and taste
- Sour cream: Creates the rich, tangy base for our sauce. Full-fat works best for creaminess
- Cream of chicken soup: Provides body and savory depth to the sauce without extra work
- Cheddar cheese: Sharp varieties add the best flavor contrast. Freshly grated melts much better than pre-shredded
- Mozzarella cheese: Creates those perfect cheese pulls. Fresh mozzarella can be used but will release more moisture
- Garlic and onion powder: Infuse flavor throughout without the texture of fresh aromatics
- Ritz crackers or cornflakes: The secret to that golden, buttery crunch topping that makes this dish unforgettable
- Melted butter: Transforms the cracker topping into crispy, golden perfection
Step-by-Step Instructions
- Preheat and Prepare:
- Turn your oven to 375°F and ensure the rack is positioned in the center. While it heats, take a moment to properly grease your casserole dish, making sure to get into the corners where sticking often occurs. A light coating of butter or cooking spray works well here.
- Create the Creamy Base:
- In a spacious mixing bowl, combine the sour cream and cream of chicken soup first, whisking until completely smooth. This step ensures no lumps in your final sauce. Add the garlic powder, onion powder, salt and pepper, stirring to distribute the seasonings evenly throughout the creamy mixture.
- Incorporate the Proteins and Cheese:
- Gently fold in your cooked chicken pieces, ensuring they're bite-sized for the perfect texture. The chicken should be cool enough to handle easily. Next, add about 3/4 of your crumbled bacon, saving some for the top garnish. Finally, fold in both cheeses, but work quickly and with a light hand to avoid compacting the mixture too much.
- Prepare the Crunchy Topping:
- The topping makes this dish special. Place your crackers or cornflakes in a zip-top bag and crush them with a rolling pin until they're broken down but still have some texture. Melt your butter completely, then drizzle it over the crumbs while stirring, ensuring every piece gets coated for maximum crispiness.
- Assemble and Bake:
- Spread your chicken mixture evenly in the prepared dish, using a spatula to create a level surface. Sprinkle your buttery crumb mixture evenly across the top, covering the entire surface. Finish with the reserved bacon crumbles for an extra flavor boost. Bake until you see bubbling around the edges and the top turns a beautiful golden brown.
- Rest and Serve:
- Allow the casserole to rest for 5 full minutes after removing from the oven. This crucial step lets the sauce thicken and the flavors settle. Sprinkle with fresh herbs if using, which adds both color and a fresh flavor contrast to the rich casserole.

The first time I made this recipe, I accidentally added twice the amount of bacon called for. What seemed like a mistake turned into a family tradition. My daughter now insists that "extra bacon" is the only acceptable way to make this casserole, and honestly, I cannot disagree with her logic.
Make It Ahead
This casserole is perfect for meal prep and busy schedules. You can assemble the entire dish up to 24 hours before baking and store it covered in the refrigerator. When ready to bake, simply allow it to sit at room temperature for about 20 minutes before placing it in the oven. If baking directly from the refrigerator, add 5-10 minutes to the cooking time and cover with foil for the first half of baking to prevent the topping from burning before the center heats through.
Perfect Pairings
Balance the richness of this casserole with some lighter sides. A simple green salad dressed with a tangy vinaigrette cuts through the creaminess perfectly. Steamed green vegetables like broccoli or asparagus also make excellent companions. For a complete comfort food experience, warm dinner rolls or garlic bread help soak up every last bit of the delicious sauce. During warmer months, I love serving this with a side of fresh sliced tomatoes sprinkled with a little sea salt.
Customize Your Casserole
This recipe welcomes adaptation based on what you have on hand. The chicken can be replaced with leftover turkey after holidays for an entirely new meal. For a bit of brightness, stir in a cup of thawed frozen peas just before baking. Mushrooms sautéed until golden add wonderful earthy notes. If you prefer a kick of heat, add a few dashes of hot sauce to the creamy mixture or sprinkle some red pepper flakes into the topping. The casserole can also accommodate leftover cooked pasta or rice mixed into the base for a more substantial dish.
