How long will cheesy white sauce last in fridge?

And how would I reheat it?

It will freeze beautifully! Take it out the day before you need it. Reheat gently in microwave but if it's too thick, tip into pan and whisk in a bit more milk til it's the right consistency.

I freeze pots and pots of white sauce in cream pots - just the right amount for one serving.

Great thank you. I just want to use it tomorrow I think so will put in fridge but good to know for next time
