Ingredients:
- 2 cups broccoli florets
- 2 cups cauliflower florets
- 2 tablespoons unsalted butter
- 2 tablespoons all-purpose flour
- 1 ½ cups whole milk
- 1 teaspoon Dijon mustard
- 1 cup sharp cheddar cheese, shredded
- ½ cup Parmesan cheese, grated
- ½ teaspoon garlic powder
- Salt and pepper, to taste
- ¼ cup panko breadcrumbs
- 2 tablespoons fresh parsley, chopped (optional)
Instructions:
- Preheat the oven: Preheat your oven to 375°F (190°C). Grease a baking dish and set aside.
- Cook the vegetables: In a large pot, bring salted water to a boil. Add the broccoli and cauliflower florets and cook for 3-4 minutes, until just tender. Drain and set aside.
- Make the cheese sauce: In a medium saucepan, melt the butter over medium heat. Stir in the flour and cook for 1 minute, whisking constantly. Gradually whisk in the milk and cook for about 3-5 minutes until thickened. Stir in the Dijon mustard, garlic powder, cheddar cheese, and Parmesan. Season with salt and pepper to taste.
- Assemble the gratin: Spread the broccoli and cauliflower evenly in the prepared baking dish. Pour the cheese sauce over the vegetables, ensuring they are well coated.
- Top with breadcrumbs: In a small bowl, mix the panko breadcrumbs with a little melted butter (optional) and sprinkle over the top of the gratin.
- Bake: Bake the gratin for 20-25 minutes, or until the top is golden brown and crispy. If needed, broil for an additional 2-3 minutes to achieve a crispier top.
- Garnish and serve: Remove from the oven, garnish with fresh parsley if desired, and serve hot.
