The Perfect Submarine Oil: Elevate Your Deli Sandwiches
The first time I encountered what I now know as “submarine oil,” I was a wide-eyed kid perched on a stool at my grandfather’s tiny Italian deli. The aroma alone was intoxicating – a heady mix of olive oil, herbs, and something tangy that made my stomach rumble. He’d drizzle it liberally over everything from provolone and prosciutto to the simplest tomato and mozzarella. That little bottle, a magical elixir, transformed the most basic sandwich into an experience. Years later, I’ve recreated that flavor, and I’m eager to share the recipe with you.

Ingredients
- 1/2 cup extra virgin olive oil
- 1/4 cup balsamic vinegar or 1/4 cup red wine vinegar
- 1/2 teaspoon paprika

- 1/4 teaspoon finely ground black pepper

Expert Tips & Tricks
- Vinegar Variety: The choice between balsamic vinegar and red wine vinegar significantly impacts the final flavor. Balsamic provides a sweeter, more complex note, while red wine vinegar offers a sharper, more traditional tang. Experiment to find your preference!
- Spice Level: Feel free to adjust the paprika and black pepper to your liking. A pinch of red pepper flakes can also add a pleasant kick.
- Herb Power: While dried Italian seasoning is convenient, using a blend of fresh herbs (finely chopped) will elevate the flavor even further. Consider fresh oregano, basil, and thyme. If using fresh herbs, double the quantity.
- Emulsification Secret: To help the oil and vinegar combine more effectively, you can add a tiny amount (about 1/4 teaspoon) of Dijon mustard. The mustard acts as an emulsifier, creating a smoother, more stable mixture.
- Flavor Infusion: For an extra layer of flavor, infuse the oil with garlic. Gently heat a few cloves of crushed garlic in the oil over low heat for about 5 minutes, being careful not to burn the garlic. Remove the garlic before mixing with the other ingredients. Let the oil cool completely before using.
Serving & Storage Suggestions
This submarine oil is incredibly versatile. Beyond its namesake sandwich application, consider these uses:
- Drizzling: Drizzle it over grilled vegetables, salads, pasta dishes, or even pizzas for a burst of flavor.
- Marinating: Use it as a marinade for chicken, fish, or tofu.
- Dipping: Serve it with crusty bread as a simple appetizer.
- Sandwich Enhancement: Brush it on the bread before assembling your sandwiches to prevent sogginess and add an extra layer of deliciousness.
To store, keep the submarine oil in an airtight glass container at room temperature, away from direct sunlight and heat. It will keep for several weeks, and the flavors will actually improve over time. There’s no need to refrigerate, as refrigeration can cause the oil to solidify. If the oil does solidify slightly, simply let it come to room temperature before using.

Variations & Substitutions
- Spicy Sub Oil: Add a pinch of red pepper flakes or a dash of your favorite hot sauce for a spicy kick.

- Garlic Lover’s Oil: Add 1-2 cloves of minced garlic to the oil for a more intense garlic flavor. Allow the oil to sit for at least an hour before using to allow the garlic flavor to infuse. Be sure to use it within a few days to prevent the garlic from becoming bitter.

- Herb Infusion: Experiment with different dried herbs like oregano, thyme, rosemary, or basil to create your own unique blend.
