A stunning centerpiece that transforms the humble cauliflower into a decadent, cheesy masterpiece. This whole-baked version features a rich, velvety mornay sauce and a golden, bubbling crust that's perfect for Sunday roasts or a vegetarian main.
Bring a large pot of salted water to a boil. Remove any large outer leaves from the cauliflower, but keep the smaller, tender ones attached. Carefully lower the whole cauliflower into the water and boil for 15 minutes. Drain thoroughly and set aside.
Preheat your oven to 180°C (160°C fan/gas 4). In a medium saucepan, melt the butter over medium heat. Stir in the flour and sweet smoked paprika, cooking for 1-2 minutes to create a roux.
Remove the pan from the heat and gradually whisk in the milk until the mixture is smooth and lump-free. Stir in the English mustard. Return the pan to the heat and bring to a boil, whisking continuously until the sauce thickens.
Stir in two-thirds of the cheese and whisk until completely melted. Taste and season with salt and pepper as needed.
Place the boiled cauliflower in the center of a deep baking dish. Pour the cheese sauce evenly over the top and sprinkle with the remaining cheese. Bake uncovered for 30-35 minutes until the sauce is golden brown and bubbling.
Scatter the finely chopped chives over the cauliflower just before serving.
To prevent a watery sauce, ensure the cauliflower is very well-drained and patted dry after boiling. For extra crunch, you can mix a handful of panko breadcrumbs with the final layer of cheese before baking.
