How to make Bechamel sauce without butter - it's creamy, silky smooth and so delicious. Use this sauce for many classic comfort food dishes even if you've run out of butter.
Add the olive oil to a saucepan and warm it for a couple of seconds before adding the flour.
Once the flour has been added mix it together with a whisk or wooden spoon to form a paste and let it cook for one minute (this cooks the flour so you don't have a floury taste in your sauce).
Add 1/4 of the milk and whisk constantly to remove any lumps. Once it has started to thicken add a little more milk (around 1/4 at a time) until you have used up all the milk.
Continue to heat the sauce whilst stirring until thick. Once it's thick enough to coat the back of a metal spoon, take it off the heat and add nutmeg, salt and pepper and cheese if making a cheese sauce.
If making a cheese sauce stir the sauce until the cheese has melted. You may need to put it back on the heat for a few seconds. If it thickens too much add another splash of milk.
Notes
The best cheese to add to bechamel sauce is something that melts well such as parmesan, gruyere, fontina or cheddar.
