Does marmite go bad?

In this article, we will answer the question “Does marmite go bad?”, can out-of-date marmite make you sick, what foods should not be eaten past their expiration, and how to eat marmite.

Does marmite go bad?

Although marmite has a pretty long shelf-life, it eventually goes bad. The best-by date printed on the marmite container only informs us about how long the product will retain peak quality. The product may not necessarily go past the printed date. However, you can discard your marmite if it has an off-taste or off-smell.

Can out-of-date marmite make you sick?

No, out-of-date marmite won’t make you sick. Marmite does not come with an expiry date but a best-by or a best-before date. The best-by timeline is more or less 18 months. It can go up to 2 years. 

Marmite can be safely consumed past the printed date because It has a lot of added salt. The salt acts as a preservative and makes marmite shelf-stable. 

What foods should not be eaten past their expiry?

Perishable foods like deli meat, raw eggs, ready-to-eat foods that are not heated, and unpasteurized dairy products should not be consumed past the expiration date. 

Deli meat 

Listeria is capable of surviving the refrigeration environment. Therefore, opened deli meat should be discarded after 3-5 days of refrigeration. 

Listeria can also multiply in the food processing plants where deli meat is being cooked and packaged. Besides, listeria can survive in soil, water, and in certain animals.


Eggs should be consumed within 5 weeks of their purchase. As time passes, eggs lose moisture which is replaced by gasses. All of this takes place through the porous shell of an egg. An old egg can be easily identified by performing the float test or egg candling. 

Fresh berries 

Berries are very perishable due to their high moisture content. Berries should only be washed when you are ready to eat them. It is because washing will leave water drops over the surface of berries that will promote the growth of bacteria and fungi.

How to eat marmite?

Method 1: Surviving marmite spread taste 

Marmite has a very overpowering taste due to large amounts of salt and yeast. Its flavor is best enjoyed in small amounts. You can spread a pea-sized amount of Marmite spread on your toast, cracks, or bread. Spread it in a very thin layer. 

Mix with another spread to cut the flavor 

If you are new to marmite, you should try spreading it along with another rather subtle flavored spread. This helps balance the strong yeasty and salty flavor of marmite. Butter, in particular, is a very good choice in this regard. 

Take small bites 

To familiarize yourself with the strong taste of marmite, you should eat it in smaller amounts. Taking small bites of any food or drink with marmite will slowly make you accustomed to the flavor of this spread.

Take big drinks with each bite 

To prevent the strong flavor of marmite from lingering in your mouth after each bite, take a sip of your favorite drink after each bite. 

It could be plain water, your favorite soft drink, or even a cocktail. The drink will act as a chase, keeping your palate clean and ready for the next bite of marmite. 

Try not to smell marmite before you eat it

Marmite does not have a very pleasant taste. So, If you have sniffed it before even starting to eat, chances are you will back off after 2 or 3 bites. To get used to the flavor of marmite and like it, you need to be patient and biased before taking the first bite.

Eat marmite with strong-tasting foods 

Diamond cuts diamond. To balance the strong flavor of marmite, you need to pair it with equally strong-flavored foods like garlic or seafood, meat or cheese, etc. alternatively, use marmite in smaller amounts as part of a big recipe.

Method 2: Using marmite in recipes 

Add marmite to soups and stews 

Marmite goes great in soups and stews. It provides a rich and savory flavor profile to the soups whilst adding brown color. You can use marmite in place of beef stock in french onion soup. Just mix a heaping tsp of marmite to use in place of beef stock. 

If you are vegan, try making your vegetable soup with marmite. Mix marmite in water and add your favorite vegetable slang with some oil in the soup and voila!

Pair marmite with cheeses 

The strong taste of marmite pairs well with the bold taste of sharp cheddar cheese. This combination makes for a perfect breakfast when spread over toast along with some butter.

Use marmite as a glaze for roast meats 

Marmite makes for a great ingredient for glazes and sauces for meat, poultry, and seafood. Baste your roasted chicken with a mixture of melted butter and marmite for a delicious umami flavor in the outer crust. 

When using marmite as a glaze for meats, skip the regular salt. Instead, use forego sprinkling salt to balance the saltiness.
