How Long does White Sauce Last in the Fridge?

It usually surprises people to learn how well white sauce freezes. Although I have discovered a small tub of sauce that was 12 months old and still good during a fridge clean-up, the sauce can be stored for up to three months.

The bechamel (white) sauce needs to be mildly reheated before use and can be stored in the refrigerator for up to five days. While highly convenient if you want to jump on your meal plan, save the sauce in the freezer if you don’t want to use it immediately or if you have leftovers from a meal.

What is the Best Advice on Freezing White Sauce?

It’s time for you to start freezing it right away. The most crucial action is to wait until the white sauce has completely cooled to room temperature before freezing it. Afterwards, you can move:

  • Grab a freezer bag, then spoon your sauce inside. To defrost portions at a time, you should spoon in the amount of one portion. Fill bags as needed until all of the sauce has been utilized.
  • Seal: Tightly close the bags, squeezing out as much air as you can in the process.
  • Find a container that can hold all your bags and place them inside. Because milk and cheese can absorb other freezer odors that can ruin your silky smooth white sauce, we double-layer both ingredients.
  • Freeze: Pack the container with the bags, cover it with tape, and put it in the freezer.

  • All-Purpose Flour – Flour thickens this sauce when combined with milk and butter.

The best way to store white sauce is to freeze it after it has been prepared. Ensure that you leave a small amount of head space in the container. The sauce will expand when frozen, so don’t put it in a glass container – it can break and leak. Use resealable plastic bags or a rigid freezer-safe container to store your sauce. Leave about an inch of head space and cover the container tightly with an airtight lid. Write the date and storage instructions on the container.

Refrigeration can keep white sauce fresh for several days. However, it’s important to keep a careful eye on it. If the sauce begins to smell unpleasant, throw it away. Some people opt to save the liquid and reheat it. But this could cause the sauce to turn lumpy. When this happens, whisk the sauce vigorously to remove lumps.
