Ingredients For French Onion Dip Recipe
Sour cream: Provides a tangy and creamy base for the dip.
Mayonnaise: Adds richness and a smooth texture to the dip.
Onions: Caramelized to bring out their natural sweetness and depth of flavor.
Olive oil: Used for cooking the onions until they are perfectly caramelized.

Technique Tip for Making This Dip
When caramelizing onions, ensure you cook them slowly over medium heat to develop a deep, rich flavor. Stir occasionally to prevent burning, and if they start to stick, add a splash of water to deglaze the pan. This process can take up to 30 minutes, but the result is worth the extra time.

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. The dip will stay fresh for up to 5 days, allowing you to enjoy it over multiple occasions.
- Before serving, give the dip a good stir to ensure the caramelized onions are evenly distributed throughout the sour cream and mayonnaise mixture.
- If you plan to freeze the dip, portion it into smaller containers. This makes it easier to thaw only what you need, reducing waste.
- When freezing, make sure to leave some space at the top of the container. Sour cream and mayonnaise can expand slightly when frozen.
- Label each container with the date. This helps you keep track of how long the dip has been stored.
- To thaw, move the container from the freezer to the refrigerator. Allow it to thaw slowly overnight for the best texture.
- Once thawed, give the dip a good stir. The consistency might change slightly, but a thorough mix will help restore its creamy texture.
- Avoid refreezing the dip once it has been thawed. This can affect the quality and safety of the French Onion Dip.
- For an extra burst of flavor, consider adding a sprinkle of fresh chives or a dash of paprika before serving.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Transfer the French onion dip to an oven-safe dish. Cover with aluminum foil and bake for about 15-20 minutes, or until heated through. Stir halfway to ensure even heating.
For a quicker method, use the microwave. Place the dip in a microwave-safe bowl. Heat on medium power for 1-2 minutes, stirring every 30 seconds until warm. Be cautious not to overheat, as it can cause the sour cream and mayonnaise to separate.
If you prefer stovetop reheating, use a double boiler. Fill the bottom pot with water and bring it to a simmer. Place the dip in the top pot and stir occasionally until warmed through. This gentle method helps maintain the creamy texture.
For a unique twist, reheat the French onion dip in a slow cooker. Set it on low heat and stir occasionally until the dip is warm. This method is perfect for keeping the dip warm during a party or gathering.
