This Cauliflower & Broccoli Au Gratin is a rich and creamy dish that’s perfect as a side or even a main course for vegetarians. The vegetables are lightly steamed to retain their crispness before being enveloped in a decadent, cheesy béchamel sauce. The golden, crunchy breadcrumb topping adds texture, while the sharpness of cheddar cheese perfectly complements the mild flavor of the cauliflower and broccoli. This comforting and elegant dish is great for holiday meals, family dinners, or any time you crave something hearty and flavorful.
Ingredients:
- 1 medium head of cauliflower, cut into florets
- 1 medium head of broccoli, cut into florets
- 2 tablespoons unsalted butter
- 2 tablespoons all-purpose flour
- 1 ½ cups whole milk
- 1 cup shredded sharp cheddar cheese
- ½ cup grated Parmesan cheese
- ¼ teaspoon nutmeg (optional)
- Salt and pepper, to taste
- ½ cup breadcrumbs
- 1 tablespoon olive oil
- Fresh parsley, chopped (for garnish)
Instructions:
- Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
- Steam the vegetables: In a large pot of boiling water, steam the cauliflower and broccoli florets for about 5-7 minutes, or until just tender. Drain and set aside.
- Make the béchamel sauce: In a medium saucepan over medium heat, melt the butter. Stir in the flour and cook for 1-2 minutes, stirring constantly, until the flour is lightly golden. Slowly whisk in the milk and cook until the mixture thickens, about 5 minutes. Season with nutmeg, salt, and pepper.
- Add the cheese: Remove the sauce from heat and stir in the cheddar and Parmesan cheeses until melted and smooth.
- Assemble the gratin: Place the steamed cauliflower and broccoli into the prepared baking dish. Pour the cheese sauce evenly over the vegetables, making sure they are well coated.
- Prepare the topping: In a small bowl, mix the breadcrumbs with olive oil. Sprinkle the breadcrumb mixture over the top of the cheese-covered vegetables.
- Bake the gratin: Place the dish in the preheated oven and bake for 20-25 minutes, or until the top is golden brown and bubbly.
- Garnish and serve: Remove from the oven and let the gratin cool for a few minutes. Garnish with fresh parsley before serving.
Enjoy this creamy, cheesy goodness!
