Roasted Cauliflower with Cheddar Cheese Sauce

This roasted cauliflower with cheddar cheese sauce is the ultimate vegetarian comfort food, offering a sophisticated twist on a British classic. By steaming the cauliflower whole before roasting, the florets maintain a perfect texture that pairs beautifully with the rich, velvety cheese sauce. The result is a bubbling, golden-brown gratin that feels both indulgent and nutritious, making it a standout centrepiece for any meat-free meal.

Ideal as a substantial main course or a luxurious side dish for a traditional Sunday roast, this recipe relies on high-quality mature cheddar to provide a deep, savoury flavour. It is a family-friendly favourite that is remarkably simple to prepare, yet looks elegant when brought straight from the oven to the dining table. Serve it alongside crisp green vegetables or a fresh seasonal salad for a balanced and satisfying dinner.

Ingredients for Roasted Cauliflower with Cheddar Cheese Sauce

  • 1 large head cauliflower (about 450g total)

  • 4 tablespoons (1/2 stick) unsalted butter

  • 30g plain flour

  • 1/8 teaspoons fine sea salt

  • 475ml whole milk

  • 275g Cheddar cheese or similar, grated (about 300ml )

  • 12- by 8-inch baking dish

Position a rack in the middle of the oven and preheat to 191°C. Arrange a steamer rack over a large pot of boiling water.

Remove the green outer leaves from the cauliflower, place it on the steamer rack, and steam until tender, about 10 minutes. Transfer to a large bowl to cool. Once the cauliflower is cool enough to handle, use your hands to gently break the florets from the thick central stalk—try to break the cauliflower into large florets rather than small pieces. Arrange the florets, in one layer, in a 12- by 8-inch baking dish and set aside.

In a large heavy saucepan over moderate heat, melt the butter. Reduce the heat to low, add the flour and salt, and whisk until both are incorporated and the mixture turns golden brown, about 2 minutes. Raise the heat to moderate and add the milk, whisking constantly, until a smooth sauce forms (the sauce should be thick and glossy, but still runny), about 5 minutes. (If the sauce is too thick, gradually whisk in additional milk until the desired consistency is achieved.) Add 120g the grated cheese and whisk until melted, about 1 minute. Pour the cheese sauce over the cauliflower, making sure to cover all the florets. Sprinkle with the remaining 30g cheese and season with pepper, then bake until the cauliflower is golden brown and the cheese sauce is bubbling, about 30 minutes.
