- Sour cream: Full-fat sour cream provides a rich, creamy texture, but you can use low-fat if preferred.
- Mayonnaise: Adds richness and helps to stabilize the dip’s texture.
- Worcestershire sauce: A small amount adds depth and umami flavor.
- Garlic powder and onion powder: These enhance the overall onion flavor without overpowering the dip.
- Salt and black pepper: Adjust to taste, but start with the recommended amounts.
For substitutions, Greek yogurt can replace sour cream, and you can use olive oil instead of butter for a dairy-free version. Always taste and adjust seasoning after making substitutions.
Professional Tips & Techniques
- Caramelizing onions: Cook onions slowly over medium heat to develop their natural sugars without burning. Stir occasionally to prevent sticking.
- Cooling onions: Allow the caramelized onions to cool completely before mixing with the dairy to prevent curdling.
- Chilling time: Refrigerate the dip for at least an hour before serving to let the flavors meld together. This step is crucial for the best taste.
- Seasoning balance: Start with less salt and pepper, as you can always add more, but you can’t take it away.
- Visual cues: The onions are done when they are a deep golden brown. If they start to burn, reduce the heat.

French Onion Dip
Equipment
- Large skillet
- Mixing bowl
- Spatula or spoon
Ingredients
- 2 large yellow onions thinly sliced
- 2 tablespoons unsalted butter
- 1 cup sour cream full-fat preferred
- 1/2 cup mayonnaise
- 1 teaspoon Worcestershire sauce
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/4 teaspoon salt or to taste
- 1/4 teaspoon black pepper freshly ground
Instructions
- In a large skillet, melt the butter over medium heat. Add the sliced onions and cook, stirring occasionally, until they are caramelized and deeply golden brown, about 25-30 minutes. This slow cooking process helps to develop the rich, sweet flavor of the onions.
- Once the onions are caramelized, remove them from the heat and let them cool to room temperature. This step is crucial as it prevents the heat from the onions from curdling the sour cream and mayonnaise when mixed.
- In a mixing bowl, combine the sour cream, mayonnaise, Worcestershire sauce, garlic powder, onion powder, salt, and black pepper. Stir until well mixed.
- Add the cooled caramelized onions to the sour cream mixture and stir until evenly distributed. Taste and adjust seasoning if necessary.
- Cover the dip and refrigerate for at least 1 hour before serving to allow the flavors to meld together. This resting time is essential for the best flavor.
