Why Do People Put Oil On Their Sub Sandwiches?

Oil by itself might sound like an odd thing to add to a sandwich, but many people do enjoy it as a topping. That said, the flavor and moisture that oil adds to a sandwich can appeal to many.

In addition to oil, many people also request vinegar on a Subway sandwich. With that, the vinegar helps cut through the oil’s fattiness and the meat on the sub sandwich.

Also, even though Subway’s oil is 90% canola and only 10% olive oil, it tastes like olive oil, an appealing flavor to many people, and is commonly found on subs and hoagies.

If you’ve never tried this combination on a sub, consider requesting it next time you order from Subway, you just may find you like this simple yet delicious addition to your sandwich.

Does Subway Have Any Flavored Oils?

While Subway offers its plain canola and olive oil blend at all Subway restaurant locations, some restaurants also carry an herb and garlic oil blend.

That said, herb and garlic oil first launched in 2018 in several locations with plans to expand further. However, time will tell if it remains on the menu permanently.

Moreover, this herb and garlic oil is described as “oil blended with roasted garlic, basil, and Italian herbs.”

So, it is unclear what type of oil is used from this description, but presumably, it’s the same canola/olive oil blend.

At this time, no other seasoned oils appear to be on the Subway menu.

However, many people request oregano, salt, and black pepper in addition to oil on a Subway sandwich, essentially creating flavored oil.

What Steps Is Subway Taking To Ensure Sustainable Sourcing Of Palm Oil?

What Steps Is Subway Taking To Ensure Sustainable Sourcing Of Palm Oil?

Many people have become increasingly concerned about the destruction of natural habitats in the harvesting of palm oil.

For this reason, more and more companies are seeking more sustainable methods.

However, Subway does not use palm oil in very many items except in some of its bread. That said, this is due to the quality of the finished product when using palm oil.

Also, palm oil contains no trans fats, which is a plus!

To reduce harm to the environment, Subway sources palm oil from the Roundtable on Sustainable Palm oil, or RSPO.

Further, RSPO is a trusted organization dedicated to better methods of harvesting palm oil.

Is Subway Oil Vegan?

For those who follow a vegan diet, or anyone just curious about healthier types of condiments, it may be good news to learn that Subway’s oil is vegan.

In fact, both types of oil served at Subway (regular and herb and garlic oil) are vegan.

In addition, several other popular condiments are also vegan, so Subway really does have many vegan choices.

What Are Some Other Toppings That Pair Well With Subway Oil?

While many people immediately think of pairing oil with vinegar on a sandwich, it’s not the only thing that can be served with oil on a sub.

Besides vinegar, mustard is also a good choice with oil because mustard itself contains vinegar and is acidic like vinegar.

Additionally, mustard and oil are common ingredients in many salad dressings as well.

Moreover, another topping that would go with oil on a sub would be any optional spices such as oregano, salt, and black pepper.

Also, if Subway has red pepper flakes, garlic salt, or other spices, you could try those.

Can You Buy Subway Oil?

It doesn’t appear that you can purchase the oil that is used at Subway. However, you may be able to request an extra cup of Subway’s oil or herb and garlic oil, so definitely ask if in doubt!

To know more, you can also see our posts on whether or not Subway has salads, if Subway has vegan options, and if Subway has wraps.


For a topping on sandwiches, Subway offers two different types of oils.

For example, a mild oil blend of canola and olive oils is a popular choice that goes nicely with vinegar or any other toppings and spices.

Also, Subway has an herb garlic oil available in some stores but not all of them.

As far as cooking oils, in addition to canola and other vegetable oils, Subway uses small amounts of palm oil, but Subway is making strides in using more sustainable sources.
