Brussel Sprout Casserole is a creamy, cheesy side dish loaded with tender Brussels sprouts and crispy bacon. It’s a great place to start if you want to win over someone who usually skips Brussels sprouts.

Serve this alongside roast turkey, crockpot ham, or honey garlic pork tenderloin for a hearty and delicious meal.

Holly’s Recipe Highlights: Brussel Sprout Casserole

  • Flavor: Creamy, cheesy, and savory, with smoky bacon and a crisp, golden panko topping that balances the earthy Brussels sprouts.
  • Why Make It: Precooking the halved Brussels sprouts helps them become tender quickly, so the casserole only needs about 15 minutes in the oven to turn bubbly and golden.
  • Tools: An 8×8-inch baking dish keeps the casserole filling deep enough to stay creamy and bake evenly.

Ingredient Notes

  • Brussels Sprouts: Choose firm, bright green sprouts and remove any damaged outer leaves. Trim the stem ends and halve the sprouts so they cook quickly and evenly.
  • Bacon: Cook the bacon until crisp before adding it so it retains some texture in the creamy casserole. Precooked real bacon pieces are also a convenient shortcut.
  • Heavy Whipping Cream: Creates a rich, creamy sauce without a separate roux. Half-and-half can be used for a lighter casserole, but the finished sauce will be thinner.
  • Cheddar Cheese: Sharp cheddar adds the most flavor, while shredding it from a block generally produces a smoother melt. Bagged shredded cheese is an easy shortcut, and you can also substitute Gruyère, Monterey Jack, Swiss, or a cheddar blend.
  • Panko Bread Crumbs: Their coarse, airy texture creates a lighter, crunchier topping than traditional breadcrumbs.

Golden Creamy Casserole Tips

  • Drain the Water: Drain the cooked Brussels sprouts thoroughly. Excess water is the biggest enemy of a creamy sauce.
  • Cut Large Brussels: Quarter especially large sprouts so all the pieces cook at approximately the same rate and become evenly tender.
  • Boil Brussels Until Slightly Firm: Keep the sprouts slightly firm after boiling since they continue cooking in the oven.
  • Get a Head Start: Cook the bacon ahead and refrigerate it for a quick head start on dinner.
  • Make Ahead: Assemble the creamy portion ahead if needed, refrigerate it, then add the panko immediately before baking so the topping stays crisp.

Leftovers Made Easy

  • Keep leftovers in an airtight container in the refrigerator for up to 4 days and in the freezer for up to 3 months. After freezing Brussels will be less crisp. Thaw overnight in the refrigerator.
  • Reheat in a 350°F oven, covered loosely with foil, for 15 to 20 minutes or until heated through. Remove the foil during the last 5 minutes so the panko topping can crisp up.

  1. I make this for church potlucks. I triple the recipe. Prepare the ingredients the night before, then assemble and bake Sunday morning. Before I leave for church I cover with heavy duty foil, then wrap in a thick bath towel to keep the heat in. This dish is always eaten up before any of the other dishes. Yummy!
