How to Make Subway Sweet Onion Sauce Copycat

  1. In a small saucepan, whisk together 1/2 cup mayonnaise, 1/4 cup white vinegar, 2 tablespoons sugar, 1 tablespoon yellow mustard, 1 teaspoon dried minced onion, 1/2 teaspoon salt, and 1/4 teaspoon black pepper.
  2. Bring the mixture to a gentle boil over medium heat, whisking constantly to prevent sticking.
  3. Reduce heat to low and simmer for 5-7 minutes, stirring frequently, until the sauce has thickened slightly and the flavors have melded. The sauce should coat the back of a spoon.
  4. Remove from heat and let the sauce cool completely before transferring it to an airtight container.
  5. Refrigerate for at least 30 minutes to allow the flavors to fully develop. Serve chilled as a delicious dipping sauce for sandwiches, salads, or as a topping for your favorite dishes!
