Add t500 g Brussels sprouts to a pan of boiling water and simmer for 4 minutes.
In a separate pan, melt 50 g Butter and add 2 Shallots. Cook until softened, about 4 minutes.
Add 4 tablespoon Plain flour and mix together.
Add 500 ml Semi-skimmed milk and whisk it in. Add 100 ml Single cream and whisk again.
Add 90 g Cheddar cheese and 1 tablespoon Dijon mustard. Heat gently until the cheese has melted.
Transfer the cooked sprouts to a baking dish and pour over the cheese sauce.
Sprinkle over 40 g Panko breadcrumbs and 1 sprig Thyme. Bake in the oven for 25-30 minutes.
Notes
We used fresh Brussels sprouts for this recipe. If you are using frozen, then you will need to cook them in boiling water for a little longer.
Don't cook the sprouts in the pan for too long. They will still need to be a little hard, as they will continue cooking in the cheese sauce in the oven.
Add some paprika and cayenne is nice if you want a smoky flavour.
You can use cheddar, Parmesan or mozzarella in the cheese sauce.
