One of the best things about this recipe, in my opinion, is that you can use Brussels sprouts fresh from the produce section or frozen Brussels sprouts. Because we live in an area of the world where we get produce that’s mainly in-season I can’t always get fresh Brussels sprouts when I want them. If you’re making this recipe with fresh Brussels sprouts, be sure to parboil or lightly steam them first. If you’re making it with frozen Brussels sprouts, simply thaw and follow the recipe as directed!

Easy Brussels Sprouts Gratin with Bacon
Recipe: Ingredients
- 8 slices bacon
- 4 tablespoons unsalted butter
- 3 tablespoons all purpose flour
- 1/3 cup dry white wine
- 2 1/2 cups milk
- 2 cups shredded cheddar cheese
- 2 cups shredded mozzarella cheese
- 1 cup parmesan cheese freshly grated
- a pinch of nutmeg
- salt and pepper (to taste)
- 1 kilo Brussels Sprouts (fresh or frozen, thawed, about 2 pounds)
- 1 cup panko breadcrumbs
- 2 tablespoons bacon fat (reserved)
Recipe: Instructions
- Preheat your oven to 375 degrees Fahrenheit.
- In a large oven-safe skillet (cast iron is best) over medium heat, cook the bacon just until barely crisp. Remove the bacon to a plate.
- Remove the bacon fat from the pan and reserve it in a bowl.
- If using fresh Brussels sprouts, slice them in half and parboil them in some water for about 3 minutes or until bright green and just barely soft. If using frozen Brussels sprouts, let them thaw in the fridge overnight or run them under some hot water to thaw completely before using. If possible, slice them in half.
- Add the butter to the pan and when it's bubbly, add the flour and whisk to combine.
- Toast the flour and butter mixture for about 1 minute, stirring constantly, and add the wine.
- Whisk the flour mixture and wine together until combined (about 1 minute) and then slowly add the milk about 2 tablespoons at a time, whisking constantly.
- Continue whisking and turn the heat to medium low as the mixture bubbles.
- Add the cheeses one at a time and continue whisking as they melt into the sauce.
- Add the nutmeg and salt and pepper (to taste).
- Add the Brussels sprouts and stir well to combine.
- Crumble the bacon and stir it in too. Turn off the heat under the pan and smooth out the top of the mixture.
- In a bowl, combine the panko breadcrumbs with about 2 tablespoons of the warm (liquid) bacon fat. Sprinkle the breadcrumb mixture over the top of the creamy Brussels Sprouts mixture to form a crust.
- Bake for about 25-30 minutes at 375 degrees Fahrenheit or until the sauce is bubbly and the crust is golden brown.
