Cauliflower and Bacon Gratin Recipe

Preheat oven to 375°F.

Bring a large pot of water to a boil. Cook cauliflower florets over medium-high heat for about 5 minutes. Drain then set aside.

Melt butter in a saucepan over medium heat. Set aside half of the melted butter. Add flour, stirring constantly for 2 minutes. Slowly add milk, stirring, and allow mixture to boil. Whisk constantly until thick, about 5 minutes. Remove from heat. Add cheddar cheese and about ¹⁄³ cup Parmesan cheese. Season with salt and pepper.

Pour some of the sauce into an 8-inch oval baking dish. Add cauliflower, then top with remaining sauce. Sprinkle with remaining Parmesan cheese, and drizzle with remaining melted butter. Top with bacon.

Bake in the preheated oven until top bubbles, about 15 minutes.
