Step 1

Place cauliflower florets in a large saucepan and cover with around 1.5 L / 3 pints of water. Bring to the boil and boil for 15-20 mins or until cauliflower has softened (test with a fork). Drain and transfer to a baking dish.

Step 2

Melt the butter in the same saucepan you used to cook the cauliflower, on medium - high. Add cornstarch / cornflour and stir well with a whisk for about 1 minute to make sure it’s cooked through. This will stop it tasting like flour in the final sauce. Tip: Aim for a lemon curd consistency here - if it’s too thin, add another ½ tbsp cornstarch / cornflour and mix well.

Step 3

Turn off the heat to pour in milk (this will stop the sauce becoming lumpy). Whisk through quickly, then pop back onto low heat and keep whisking until thickened, around 1 minute. Tip: If the sauce becomes too thick at this stage, add a little more milk to loosen.

Step 4

Add 1 cup of cheddar cheese and stir to melt it through the sauce. Tip: You can increase heat slightly to help the cheese melt if needed.

Step 5

Season with nutmeg, and optional salt and pepper to taste. Mix well. Tip: If the sauce is too thick to pour, add a little more milk once again to loosen.

Step 6

Pre-heat oven to 180°C / 360°F.

Step 7

Pour the cheese sauce over the cauliflower florets, making sure each piece is well coated. Top generously with remaining 1/2 cup cheddar cheese. Bake for around 20 minutes or until the cheesy top is bubbly and golden brown.
