How to make  Cauliflower Gratin

Ingredients

Here’s what you’ll need to create this cheesy masterpiece:

• 1 medium head of cauliflower (about 2 pounds), cut into florets
• 2 tablespoons unsalted butter (plus extra for greasing)
• 2 tablespoons all-purpose flour
• 1 ½ cups whole milk (warm)
• ½ cup heavy cream
• 1 cup Gruyère cheese, grated
• ½ cup Parmesan cheese, grated
• ½ teaspoon garlic powder
• ½ teaspoon nutmeg (optional but recommended)
• Salt and freshly ground black pepper, to taste
• ½ cup breadcrumbs (panko works great for crunch)
• 1 tablespoon olive oil (for mixing with breadcrumbs)
• Fresh parsley (optional garnish)

Directions

1. Blanch the cauliflower: Bring a pot of salted water to a boil. Add cauliflower florets and cook for 5 minutes until slightly tender. Drain and set aside.
2. Prepare the béchamel: Melt butter in a medium saucepan over medium heat. Whisk in flour and cook for 1–2 minutes to create a roux. Slowly whisk in warm milk and cream, stirring continuously until smooth and thickened.
3. Season the sauce: Add garlic powder, nutmeg, salt, and pepper. Stir in half of the Gruyère and Parmesan until melted and creamy.
4. Assemble: Spread a thin layer of sauce in the greased baking dish. Arrange cauliflower florets and pour the remaining sauce over them. Sprinkle with remaining cheese.
5. Top and bake: Mix breadcrumbs with olive oil, then sprinkle on top. Bake for 25–30 minutes until golden and bubbly.
6. Optional broil: For an extra-crispy crust, broil for 2 minutes.
7. Serve: Garnish with fresh parsley and serve warm.
