• 2 tablespoons white sugar
• 1 teaspoon salt
• 1/2 teaspoon ground black pepper
• 1/4 cup mayonnaise

The key to this recipe’s success lies in the balance of the onions and the vinegar.

👩‍🍳 Step-by-Step Guide to Perfection

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.

• Beverage Pairing: This versatile sauce pairs wonderfully with a crisp, refreshing white wine or a citrusy non-alcoholic beverage like lemonade or iced tea.

🔍 Troubleshooting Common Recipe Issues

• Mistake 1 – Overcrowding the Pan: When sautéing the onions, be sure not to overcrowd the pan. This can cause the onions to steam instead of searing, resulting in a less caramelized flavor. Cook the onions in batches if necessary to ensure even browning.
• Mistake 2 – Using Cold Ingredients: Make sure all the ingredients, especially the vinegar and mayonnaise, are at room temperature before adding them to the sauce. This will help the sauce emulsify properly and achieve a smooth, creamy texture.
• Mistake 3 – Not Blending Thoroughly: Take the time to blend the sauce until it’s completely smooth and creamy. Any remaining chunks of onion can affect the overall texture and mouthfeel of the final sauce.

🕒 A Guide to Storing for Later

• Refrigeration: Store the Subway Sweet Onion Sauce in an airtight container in the refrigerator for up to 1 week.
• Freezing: This sauce can be frozen for up to 3 months. Transfer it to a freezer-safe container or resealable bag, leaving a bit of headspace for expansion. Thaw in the refrigerator overnight before using.
• Reheating: If the sauce has thickened or separated during storage, simply give it a quick stir or whisk before using. To reheat, transfer it to a small saucepan and warm it over low heat, stirring occasionally, until it reaches the desired temperature.
