How to Make Subway Sweet Onion Sauce Step-by-Step ?

Step 1: Prepare the Base

In a mixing bowl, combine the mayonnaise, white vinegar, and balsamic vinegar. Whisk until smooth.

Step 2: Add Sweeteners and Spices

Add the corn syrup (or honey), Dijon mustard, sugar, onion powder, garlic powder, paprika, salt, and black pepper. Mix well to ensure all ingredients are evenly incorporated.

Step 3: Incorporate the Onion

Fold in the finely minced or grated onion. If you prefer a smoother sauce, blend the mixture using a blender or immersion blender.

Step 4: Adjust Consistency

If the sauce is too thick, add a tablespoon of water and whisk until you achieve your desired consistency.

Step 5: Chill and Serve

Transfer the sauce to an airtight container and refrigerate for at least 1 hour to allow the flavors to meld. Serve chilled.

Variations

1. Spicy Version: Add a pinch of cayenne pepper or a few drops of hot sauce for a spicy kick.
2. Creamier Texture: Substitute Greek yogurt for half of the mayonnaise for a lighter, creamier sauce.
3. Sugar-Free Option: Replace corn syrup and sugar with a sugar-free sweetener like stevia or erythritol.
4. Herb-Infused: Add fresh herbs like parsley or chives for an extra layer of flavor.

Cooking Notes

• For the best flavor, use fresh onions rather than onion powder alone.
• If you don’t have corn syrup, honey or maple syrup works as a great substitute.
• The sauce thickens as it chills, so adjust the consistency before refrigerating.
• Store the sauce in an airtight container in the fridge for up to 1 week.

Serving Suggestions

• Drizzle over Subway-style sandwiches or wraps.
• Use as a dipping sauce for chicken tenders or fries.
• Add to salads as a dressing.

Helpful Tips

• Taste the sauce as you go and adjust the sweetness or tanginess to your preference.
• If the sauce separates after refrigeration, give it a good stir or whisk before serving.

Tips for the Best Subway Sweet Onion Sauce
