Ingredients

• 2 cups broccoli florets
• 2 cups cauliflower florets
• 3 tablespoons unsalted butter
• 3 tablespoons all-purpose flour
• 2 cups whole milk
• 1.5 cups sharp cheddar cheese
• 0.5 cups Parmesan cheese
• 0.5 teaspoons garlic powder
• 0.25 teaspoons black pepper
• 0.5 teaspoons salt
• 0.75 cups panko breadcrumbs
• 1 tablespoon olive oil

Directions

Step 1

Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish.

Step 2

Bring a large pot of salted water to a boil. Add the broccoli and cauliflower florets and blanch for 3 minutes. Drain and transfer immediately to an ice bath to stop the cooking process. Drain again and set aside.

Step 3

In a medium saucepan, melt the butter over medium heat. Once melted, whisk in the flour and cook for 1-2 minutes until lightly golden, stirring constantly.

Step 4

Gradually whisk in the milk, ensuring there are no lumps. Cook for 3-4 minutes until the mixture begins to thicken.

Step 5

Reduce the heat to low and stir in the cheddar cheese, Parmesan cheese, garlic powder, black pepper, and salt until smooth and creamy.

Step 6

Place the blanched broccoli and cauliflower into the prepared baking dish. Pour the cheese sauce evenly over the vegetables, ensuring they are well-coated.

Step 7

In a small bowl, combine the panko breadcrumbs with olive oil. Sprinkle this mixture evenly over the top of the gratin.

Step 8

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

Step 9

Remove from the oven and let cool for 5 minutes before serving. Enjoy your creamy and cheesy Broccoli Cauliflower Gratin!
