Start by cooking your butter and flour together for a quick roux, then slowly whisk in your milk in small splashes. Taking your time with the milk is the real secret to keeping this classic béchamel silky and lump-free. Just keep gently stirring until it builds body and coats a spoon nicely.
It makes an incredible base for hearty lasagna layers, bubbling gratins, or an easy homemade mac and cheese if you melt in shredded cheese. If it sets up too much while sitting on the counter, simply whisk in a splash of warm milk to loosen it right back up.
