This hearty Cheddar Bacon Green Bean Casserole transforms the traditional holiday side into an indulgent dish worthy of any dinner table. The combination of fresh green beans, crispy bacon, and sharp cheddar creates a comforting casserole that balances freshness with rich, savory flavors.
I first made this casserole when looking for ways to convince my vegetable-averse nephew to eat green beans. The addition of bacon and cheese worked like magic, and now it's requested at every family gathering regardless of the season.
Ingredients
- Fresh green beans: deliver the perfect tender crisp texture that canned beans simply cannot match
- Sharp cheddar cheese: provides the bold flavor foundation choose an aged variety for maximum impact
- Bacon: adds smoky depth and crispy texture look for thick cut with good fat marbling
- Cream of mushroom soup: creates the classic casserole base without extra work
- Panko breadcrumbs: offer superior crunch compared to regular breadcrumbs
- Smoked paprika: brings subtle smokiness that enhances the bacon flavor
- Whole milk and heavy cream: create the perfect richness balance
Instructions
- Prepare the beans:
- Blanch green beans in boiling salted water for precisely 4 to 5 minutes until they reach that perfect bright green color and slight tenderness. This crucial step ensures they retain texture through baking rather than becoming mushy. The ice water bath immediately stops the cooking process, preserving that ideal texture.
- Cook the bacon:
- Render the bacon over medium heat until each piece reaches optimal crispiness. This takes patience, about 8 to 10 minutes, but creates both the crispy bacon pieces and the flavorful fat that becomes the foundation of our sauce. The rendered fat carries intense flavor that store bought bases simply cannot match.
- Create the cheese sauce:
- Begin with the bacon fat and butter as your flavor base, then build layers of taste with sautéed onions and garlic. The flour creates the roux that thickens everything to that perfect creamy consistency. When adding the milk and cream, pour slowly while constantly whisking to prevent any lumps from forming in your sauce.
- Assemble and bake:
- Gently fold the blanched green beans into your creamy cheese sauce, ensuring each bean gets thoroughly coated. The layering process of beans, sauce, cheese, and bacon creates distinct flavor pockets throughout the casserole. The final breadcrumb topping develops a golden crust that provides textural contrast to the creamy interior.

The smoked paprika might seem like a minor addition, but it truly transforms this dish. I discovered this secret ingredient when preparing the casserole for Thanksgiving several years ago when I accidentally grabbed smoked paprika instead of regular. The subtle smokiness complemented the bacon so perfectly that it became a permanent addition to my recipe.
Storage Tips
This casserole keeps beautifully in the refrigerator for up to 3 days when stored in an airtight container. For best results when reheating, cover with foil and warm in a 325°F oven until heated through, about 20 minutes. Remove the foil for the last 5 minutes to restore some crispness to the topping. I recommend avoiding microwave reheating which tends to make the green beans soggy and the topping soft.
Ingredient Substitutions
While fresh green beans provide the best texture, frozen green beans can work in a pinch. Thaw completely and pat dry before using. For a vegetarian version, omit the bacon and use 2 tablespoons of butter plus 1 teaspoon of liquid smoke for that smoky flavor. The cream of mushroom soup can be replaced with cream of chicken or even cream of celery soup depending on your preference. For a gluten free adaptation, use gluten free flour for the roux and replace the panko with crushed gluten free crackers or cornflakes.
Serving Suggestions
This versatile casserole pairs beautifully with holiday classics like roast turkey or ham, but also works alongside simple grilled chicken or steak for everyday meals. For a complete comfort food experience, serve it with mashed potatoes and meatloaf. During summer months, it makes an excellent accompaniment to barbecued ribs or grilled sausages. If serving for a potluck, place the casserole dish on a trivet with a serving spoon that has a large enough bowl to scoop up plenty of the creamy sauce along with the beans.
Seasonal Adaptations
Summer version can incorporate fresh herbs like basil or thyme from the garden.
Fall variation works wonderfully with addition of sautéed mushrooms.
Winter holiday version benefits from a sprinkle of nutmeg in the sauce.

Enjoy this elevated green bean casserole that is sure to become a favorite. It's a dish that brings comfort and flavor to any occasion.
