Description

Discover the secret to Subway’s iconic Sweet Onion Sauce with this easy homemade recipe. Perfectly balanced with tangy vinegar, sweet sugar, and a blend of aromatic spices, this sauce is ideal for drizzling over sandwiches, salads, or grilled vegetables. Made on the stovetop with simple ingredients, it thickens to a luscious glaze that enhances any dish.

Ingredients

Main Ingredients

  • 1/2 cup white sugar
  • 1/2 cup white vinegar
  • 1 tablespoon cornstarch
  • 1 tablespoon water
  • 1 tablespoon soy sauce
  • 2 teaspoons finely minced onion
  • 1 teaspoon poppy seeds
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/4 teaspoon mustard powder
  • 1/4 teaspoon celery seed
  • Pinch of black pepper

Instructions

  1. Combine Sugar and Vinegar: In a small saucepan over medium heat, combine the white sugar and white vinegar, stirring continuously until the sugar completely dissolves.
  2. Make Cornstarch Slurry: In a separate small bowl, mix the cornstarch with water to create a smooth slurry, ensuring no lumps remain.
  3. Add Slurry to Sauce: Slowly pour the cornstarch slurry into the saucepan while stirring constantly to prevent lumps from forming in the sauce.
  4. Add Flavorings: Stir in soy sauce, finely minced onion, poppy seeds, garlic powder, onion powder, mustard powder, celery seed, and a pinch of black pepper, mixing thoroughly to combine all ingredients.
  5. Simmer and Thicken: Bring the mixture to a gentle simmer and cook for 2 to 3 minutes, stirring often, until the sauce thickens slightly to your desired consistency.
  6. Cool and Refrigerate: Remove the saucepan from heat and allow the sauce to cool completely. Transfer it to a jar or squeeze bottle and refrigerate for at least 1 hour to let all the flavors meld together.
