Traditional gravy starts with a roux: 1:2 mixture of fat to all-purpose flour. While the fat that is used in gravy is often butter, other oils, margarine, and bacon fat can also be used. What does this mean for the cleaning up process? It means that you’re going to need to think twice about pouring this delicious sauce down the drain, as it can cause huge problems when it comes to your sewers. So, how do you properly dispose of gravy? In this article, we take a look at how you should not dispose of gravy, your best options for disposal, and whether or not you can save gravy for future use.

Harmful ways to dispose of oils & fats

Due to the fact that gravy either contains oils, fats, or both, it cannot be poured down the drain. So, does that mean that the only option is to pour your gravy in your trash bin? Unfortunately, this is not a safe option either.

Expert Home Tips tells us more about the worst ways to dispose of oils and fats:

“You might think that a small amount of oil rinsed down the sink won’t do any harm, but it all adds up. Oil and water don’t combine, meaning that the oils and fats gather together, producing fatbergs. Pouring oils and fats directly into your rubbish bin can result in oils spilling out when bags rip. This can attract vermin and potentially be harmful to the environment. For this reason, we must take great care to place oil and fat in sealed containers when we dispose of it.”

The best way to dispose of gravy


So, how are you supposed to get rid of gravy if you can’t pour it down the sink or throw it in your garbage bin? Are you just doomed to hold onto it forever? Fortunately, there is one safe way to best dispose of gravy, and that involves letting it solidify before disposal.

Buster Plugholes explains the best way to dispose of gravy:

“Any leftover cooking fat in a roasting tray, for example, should be emptied into a container such as a fat trap or an old margarine tub. Here fats and grease can be collected and allowed to sit, cool, and solidify. At this point, the contents can be disposed of in the bin. This routine won’t take long at all and will not only help wider society but also reduce the potential for a clogged sink in your home.”

Can gravy be saved for reuse?

Unfortunately, gravy cannot last more than two days in the refrigerator without perishing, making it a bad candidate to save for reuse. While you can extend its life if you reboil it before serving it again, it’s usually best to dispose of gravy after a meal if you don’t intend on freezing it.

The Kitchn tells us more on how to reuse gravy by freezing it:

“If you don’t plan on eating up the gravy in a week, freeze it! A flour-based gravy can keep for up to four months in the freezer. Freeze it in containers, freezer bags, or even ice cube trays if you plan to use up just a little of it at a time. Unfortunately, cream or milk-based gravies will not freeze well, as these gravies will separate during the thawing process.”
