Recipe Information
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)
Instructions
Preheat your oven to 375°F (190°C).
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.
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.
Gradually whisk in the milk and heavy cream, ensuring there are no lumps. Cook the mixture for 4-5 minutes, stirring constantly, until thickened.
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.
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.
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.
Bake in the preheated oven for 20-25 minutes, or until the top is golden brown and bubbling.
Let the cauliflower au gratin cool for 5 minutes before garnishing with fresh parsley (optional) and serving.
