History of Mr. Submarine

Mr. Sub or Mr. Submarine as it was originally called,opened its 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.The sub sauce is what put this sandwich on the map.

What Makes Mr. Sub Secret Sauce so Sood

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 a special flavor is the juice from jarred pepperoncini peppers.

Why You Should Try This Sub Sauce Recipe

This sauce tastes identical to Mr. Sub’s sauce, so now, when you crave it, you don’t need to go into the restaurant to get it! It has a rich base, thanks to the soybean and olive oil, and the garlic provides umami notes.

However, the star ingredient is definitely the hot pepper juice because it gives the sauce its signature flavor. The best part is that you don’t need a special blender to make it; just give the ingredients a shake, and you’re ready to use it.


Here’s what you will need to make this copycat sub dressing recipe:

  • Soybean Oil
  • Olive Oil
  • Hot Pepper Juice (from Pepperoncini)
  • Oregano
  • Garlic

What is a Pepperoncini Pepper and How Hot is It?

Pepperoncini peppers are 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. The juice that comes from this pepper is perfect for this sub sauce.

Recipe 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. You can also whisk it in a bowl.

Other Delicious Ways to Serve This Sauce

You don’t have to limit this sauce to just homemade subs. Since it is similar to dressing but with a twist, you can use it in all sorts of creative ways.

I suggest using it on a salad to give it a zesty kick. The pepperoncini juice will give any salad a bright flavor. You can also use it on burgers, mix it into pasta salad, or drizzle it over bruschetta as a finishing touch.

What Side Dishes Can You Serve with a Sub Sandwich?

At Mr. Sub, there are plenty of sides you can pair with the sandwiches, such as baked cookies or brownies, pickle spears, or chips.

However, when you make it at home, you can always serve your sub with something else, like Dill Potato Salad or a fresh Cucumber Onion Salad. Lastly, you can’t go wrong serving the subs with your favorite soup!

How to Store Sub Sauce

Store this sauce in an airtight container to keep it as fresh as possible. It will last one to two weeks. You can store it in your pantry or the refrigerator. If storing it in the fridge, the oil may solidify so set it out on the counter about an hour before you want to use it.

If the mixture looks separated, don’t worry; that might naturally happen. You can simply shake it again to emulsify all of the ingredients together once more!
