• Cut your cauliflower into floret and cook it in a steamer. If you do not own a steam, it is not the end of the word, I have cooked it in salted boiling water before, cook it until a knife can enter the vegetable easily.

Bechamel

• Prepare your ingredients: Mise en place.
• In a pot, on low to medium heat, melt the butter.
• Add the flour.
• Stir well, you have a roux.
• Add a little bit of milk and stir. Repeat until you have poured all the milk.
• Season to taste.Stir (still on low to medium heat) until the sauce coats the back of the spoon

Assembling gratin

• In an oven dish, place the cauliflower, pour the bechamel heavenly on top of it.
• Add the cheese on top.
• Cook in the oven 15-20 minutes at 400F and serve!
