Ingredients

• 1 head cauliflower
• 4 tablespoons butter
• 3 tablespoons all-purpose flour
• 2 cups milk
• 0.5 cups heavy cream
• 1 teaspoon Dijon mustard
• 0.5 teaspoons garlic powder
• 1 teaspoon salt
• 0.5 teaspoons black pepper
• 1.5 cups sharp cheddar cheese, grated
• 0.5 cups Parmesan cheese, grated
• 0.5 cups breadcrumbs
• 1 tablespoon olive oil
• 2 tablespoons fresh parsley, chopped (optional garnish)

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

Bring a large pot of salted water to a boil. Cut the cauliflower into bite-sized florets and blanch them in the boiling water for 4-5 minutes until just tender. Drain well and set aside.

Step 3

In a medium saucepan, melt the butter over medium heat. Stir in the flour and cook for 1-2 minutes, whisking constantly, to make a roux.

Step 4

Gradually whisk in the milk and heavy cream, ensuring there are no lumps. Cook the mixture for 4-5 minutes, stirring constantly, until thickened.

Step 5

Add the Dijon mustard, garlic powder, salt, black pepper, and 1 cup of the grated cheddar cheese. Stir until the cheese is completely melted and the sauce is smooth.

Step 6

Place the blanched cauliflower in a greased 9x13-inch baking dish. Pour the cheese sauce evenly over the top, making sure all the florets are well coated.

Step 7

In a small bowl, combine the breadcrumbs, remaining cheddar cheese, Parmesan cheese, and olive oil. Mix well and sprinkle the mixture evenly over the cauliflower.

Step 8

Bake in the preheated oven for 20-25 minutes, or until the top is golden brown and bubbling.

Step 9

Let the cauliflower au gratin cool for 5 minutes before garnishing with fresh parsley (optional) and serving.
