If you live north of the border, you are probably familiar with Mr. Sub! If not, you are about to take your sandwiches and salads to the next level with this Mr. Sub Secret Sauce recipe.
History of Mr. Submarine
Mr. Sub or Mr. Submarine as it was originally called, opened it’s doors back in 1968 in Toronto, Canada. It started small but has grown to over 200 shops.
Mr. Sub is known for its submarine sandwich featured on a long baguette-type roll. The sandwich is filled with meat, cheese, and veggies. But it’s Mr. Sub Secret Sauce is what put this sandwich on the map.
What makes Mr. Sub Secret Sauce so good
It may be called Mr. Sub’s Secret Sauce but it’s not so secret thanks to one of my Canadian friends. What gives it special flavor is the juice from jarred pepperoncini peppers.
Ingredients
Here’s what you will need:
- Soybean Oil
- Olive Oil
- Hot Pepper Juice (from Pepperoncini)
- Oregano
- Garlic
How to Make Sub Sauce
Combine all the ingredients in a shaker and shake well.
Use the sauce on subs, sandwiches, or as a dressing for salads.
What is a Pepperoncini Pepper and how hot is it
Pepperoncini peppers are actually not that hot at all. The pepper hails from Italy and goes by many different names. It actually looks a little like a banana pepper and can be found in most grocery stores.
If you were to compare it to a jalapeno pepper on the pepper scale, a pepperoncini pepper is 5-80 times milder. But the juice that comes from this pepper is perfect for this secret sauce.
Cooking Tips
- If you don’t have soybean oil, you can substitute canola oil or saffron oil for it.
- A shaker is the best way to combine a salad dressing or sauce. But if you don’t have one, you can use a mason jar or anything else with a tight lid.
- Use Mr. Sub Secret Sauce on your favorite sandwich or for a salad dressing.
- Keep refrigerated in an air-tight container when not using.

This sub sauce rocked back in the day … long before Subway and the ‘also rans’ got in to the market.
The Fat Albert’s chain in Ontario, Canada also had a very similar sauce that was very close to that of the Mr. Sub Sauce … I can taste it, just thinking about it.
