This French onion dip is a classic appetizer that brings a rich, savory flavor to any gathering. The combination of caramelized onions with sour cream and mayonnaise creates a creamy, irresistible dip that pairs perfectly with chips, vegetables, or even as a spread for sandwiches.
Most of the ingredients for this French onion dip are common pantry staples. However, if you don't usually keep sour cream or mayonnaise on hand, you'll need to pick these up at the supermarket. Additionally, make sure you have enough onions as they are the star of this recipe.

Ingredients For French Onion Dip Recipe
Sour cream: Adds a tangy and creamy base to the dip.
Mayonnaise: Provides additional creaminess and a slight sweetness.
Onions: When caramelized, they add a deep, sweet flavor to the dip.
Olive oil: Used to cook the onions until they are caramelized.
Salt: Enhances the overall flavor of the dip.
Black pepper: Adds a bit of heat and complexity.
Garlic powder: Infuses a subtle garlic flavor without overpowering the dip.
Technique Tip for This Recipe
When caramelizing onions, ensure you cook them slowly over medium heat. This allows the natural sugars in the onions to break down and develop a rich, sweet flavor. Stir occasionally to prevent burning and achieve an even caramelization. This process is crucial for adding depth to your French onion dip.

finely chopped onions - Substitute with shallots: Shallots have a milder and slightly sweeter flavor compared to onions, which can add a subtle complexity to the dip.

How to Store or Freeze This Dip
To store your French onion dip, transfer it to an airtight container. This will help maintain its freshness and prevent any unwanted odors from seeping in. Place the container in the refrigerator, where it can be kept for up to 4-5 days.
If you plan to freeze the dip, it's essential to know that the texture may change slightly upon thawing due to the sour cream and mayonnaise. However, it can still be done. Spoon the dip into a freezer-safe container, leaving a bit of space at the top for expansion. Seal the container tightly and label it with the date. The dip can be frozen for up to 2 months.
When you're ready to enjoy your frozen French onion dip, transfer it from the freezer to the refrigerator and let it thaw overnight. Once thawed, give it a good stir to reincorporate any separated ingredients. If the texture seems off, you can add a bit more sour cream or mayonnaise to bring it back to its creamy consistency.
For best results, avoid freezing the dip in large batches. Instead, portion it out into smaller containers. This way, you can thaw only what you need, reducing waste and ensuring the dip remains as fresh as possible.
Always use a clean spoon when serving the dip to avoid introducing any contaminants that could shorten its shelf life.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Transfer the French onion dip to an oven-safe dish, cover it with aluminum foil, and bake for 15-20 minutes until warmed through. Stir halfway for even heating.
Use a microwave-safe bowl to reheat the dip. Microwave on medium power in 30-second intervals, stirring between each interval, until the dip is heated evenly. Be cautious not to overheat, as the sour cream and mayonnaise can separate.
For a stovetop method, place the dip in a saucepan over low heat. Stir continuously to prevent sticking and ensure even heating. This method helps maintain the creamy texture of the dip.
If you have a slow cooker, transfer the French onion dip to the cooker and set it on low. Stir occasionally until the dip is heated through, which should take about 1-2 hours. This method is ideal for keeping the dip warm during gatherings.
For a quick reheat, use a double boiler. Place the dip in a heatproof bowl over a pot of simmering water. Stir frequently until the dip is warm. This gentle heating method helps preserve the dip's creamy consistency.
