In this post, we’ll guide you through how to make a Subway Sweet Onion Sauce from scratch, including tips for perfecting the flavor, and variations to suit your preferences. Let’s get started!

Ingredients for Subway’s Sweet Onion Sauce

To make the signature Subway Sweet Onion Sauce, you’ll need the following ingredients:

  • 1/2 cup mayonnaise: This will provide the creamy base of the sauce.
  • 1/4 cup apple cider vinegar: This tangy vinegar will give the sauce a slight acidity to balance out the sweetness.
  • 1/4 cup honey: For that distinct sweetness that makes this sauce so irresistible.
  • 2 tablespoons Dijon mustard: Adds a subtle tang to balance the sweetness.
  • 1/4 cup onion powder: This gives the sauce that signature onion flavor without using actual onions.
  • 1/4 teaspoon garlic powder: Adds a savory note to the sauce.
  • Salt and pepper: To taste, to enhance the flavors of the sauce.

Instructions for Making Subway’s Sweet Onion Sauce

Step 1: Combine the Base Ingredients

In a medium bowl, combine the mayonnaise, apple cider vinegar, and honey. Stir until the mixture is smooth and well-combined.

Step 2: Add the Flavorings

Next, add the Dijon mustard, onion powder, garlic powder, salt, and pepper. Whisk until all the ingredients are fully incorporated. Taste the sauce and adjust the seasoning if necessary. You may want to add more honey for sweetness or a bit more vinegar for acidity, depending on your taste preferences.

Step 3: Chill the Sauce

Once everything is mixed well, cover the bowl with plastic wrap or transfer the sauce to an airtight container. Refrigerate the sauce for at least an hour to let the flavors meld together. Chilling the sauce helps it develop a deeper flavor and a thicker texture.

Step 4: Serve and Enjoy

Once the sauce has chilled, it’s ready to be used. Drizzle it over your favorite sandwich, wrap, or even salad. It also works wonderfully as a dipping sauce for chicken tenders or fries.

Cook Notes

Tips for Perfecting Subway’s Sweet Onion Sauce:

  • Adjust the Sweetness: Depending on your preference for sweetness, you can adjust the amount of honey. If you like a more robust sweetness, feel free to add a little extra honey.
  • Use Fresh Mayonnaise: For the best texture and flavor, use fresh mayonnaise rather than low-fat or fat-free versions. Full-fat mayo adds a creaminess that balances the acidity of the vinegar.
  • Onion Flavor Adjustment: If you want to intensify the onion flavor, you can add a small amount of finely minced fresh onion or a teaspoon of onion powder to the mix.
  • Vinegar Variety: While apple cider vinegar is a popular choice, you can experiment with white vinegar or rice vinegar for a slightly different taste. Just be mindful of the acidity balance.
  • Consistency: If the sauce is too thick after refrigerating, you can thin it out with a splash of water or additional vinegar, depending on your preferred consistency.

Variations of Subway’s Sweet Onion Sauce

While this homemade version of Subway’s Sweet Onion Sauce is delicious on its own, you can easily customize it to suit your specific taste or dietary preferences. Here are a few variations to consider:

1. Spicy Sweet Onion Sauce

If you like a bit of heat, add hot sauce, cayenne pepper, or sriracha to the sauce. Start with a small amount and taste as you go to ensure the spice level is to your liking. This version pairs well with grilled chicken or turkey sandwiches.

2. Vegan Sweet Onion Sauce

To make a vegan version of this sauce, simply swap the mayonnaise with a vegan mayo and make sure the honey is substituted with agave syrup or another plant-based sweetener.

3. Low-Fat Sweet Onion Sauce

If you’re looking for a lighter version, you can substitute the regular mayonnaise with Greek yogurt or low-fat mayo. This will provide a tangy, creamy texture with fewer calories.

4. Herb-Infused Sweet Onion Sauce

For an added layer of flavor, infuse your Sweet Onion Sauce with fresh herbs like basil, oregano, or thyme. Simply chop the herbs finely and stir them into the sauce. This version works especially well on vegetarian or Mediterranean-inspired sandwiches.
