What Does Subway Sweet Onion Sauce Taste Like?
Subways sweet onion sauce tastes as the name suggests. It is very sweet and has a somewhat tangy aftertaste. It is very flavorful and relatively rich – a little tends to go a long way.
As such, it pairs particularly well with tuna, chicken, or turkey subs.
Another popular pairing among Subway customers appears to be along with the honey mustard sauce.
It’s not something you’re going to want to add to your meatball marinara, pizza sub melt, or steak and cheese!
But other than that, it does seem to pair particularly well with the other menu items.
Besides, the sweet onion Teriyaki chicken is a testament to its combination with chicken and lean meats in general!
It is not currently possible to buy Subway Sweet Onion sauce. You can only order it in-store and have it directly added to your sandwich or salad. While some stores do offer sauces for sale, sweet onion is not typically one of them.
In fact, some Subway stores do what is known as ‘Subway Grocery’.
This essentially allows customers to buy some of their sauces, in a sauce bag.
However, you will only typically find the mayonnaise, mustard, marinara, teriyaki, ranch, or chipotle.
There is always the option to ask for more sweet onion sauce specifically, but that will be at the discretion of the staff.
That being said, there is another branded sauce that tastes very similar to that of Subway.
And you can get it directly on Amazon.
