Ingredients
• 1 cup finely chopped sweet onions
• 1/2 cup white vinegar
• 1/4 cup water
• 2 tablespoons white sugar
• 1 teaspoon salt
• 1/2 teaspoon ground black pepper
• 1/4 cup mayonnaise
Instructions
- Sauté the Onions: In a medium saucepan, sauté the finely chopped sweet onions over medium heat until they’re softened and translucent, about 5-7 minutes. Be patient and allow the onions to cook slowly, as this will help develop their natural sweetness.
- Add the Vinegar and Water: Once the onions are cooked, pour in the white vinegar and water. Bring the mixture to a gentle simmer, stirring occasionally, and let it cook for about 10-15 minutes. This step allows the flavors to meld and the sauce to thicken slightly.
- Sweeten and Season: Add the white sugar, salt, and black pepper to the simmering sauce. Stir until the sugar has dissolved completely and the seasoning is evenly distributed. Taste and adjust the seasoning as needed to achieve the perfect balance of sweet and savory.
- Blend for Creaminess: Using an immersion blender or a regular blender, carefully puree the sauce until it’s smooth and creamy. Be cautious when blending hot liquids, and be sure to leave room for expansion in the blender jar.
- Finish with Mayonnaise: Once the sauce is blended, stir in the mayonnaise until it’s fully incorporated. The mayonnaise will add a silky, luxurious texture to the final sauce.
- Chill and Serve: Transfer the Subway Sweet Onion Sauce to an airtight container and refrigerate for at least 30 minutes to allow the flavors to meld. Serve chilled and enjoy on your favorite sandwiches, salads, or as a dipping sauce.
