Ingredients
- 30 ml butter or olive oil (2 tablespoons)
- 3 medium yellow or white onions (approx. 600-700 grams), peeled and diced
- 2 cloves garlic, minced
- 360 ml light sour cream (1 1/2 cups) (or plain Greek yogurt for a lighter alternative)
- 10 ml chopped fresh chives (2 teaspoons), plus extra for garnish
- 10 ml Worcestershire sauce (2 teaspoons), to taste
- 5 ml fresh thyme leaves (1 teaspoon) (or 1.25 ml / 1/4 teaspoon dried thyme)
- 5 ml fine sea salt (1 teaspoon)
- 2.5 ml freshly-cracked black pepper (1/2 teaspoon)
Instructions
- In a large, heavy-bottomed stockpot or sauté pan, melt the butter or heat the olive oil over medium-high heat. The heavier bottom helps distribute heat evenly and prevents scorching.
- Add the diced onions to the pan. Sauté the onions, stirring every 2-3 minutes to ensure even cooking, for about 30 minutes or until they achieve a deep golden-brown, caramelized color. If the bottom of the pan starts to develop dark, stuck-on bits, deglaze it with a tablespoon or so of water at a time, scraping with a wooden spoon to incorporate the flavorful fond back into the onions. This slow caramelization is key to developing the rich, sweet depth of flavor for the dip.
- Add the minced garlic to the caramelized onions and continue to sauté for 1-2 minutes until it becomes fragrant. Be careful not to burn the garlic, as it can turn bitter. Remove the pan from the heat and transfer the hot onion mixture to a medium mixing bowl. Refrigerate the mixture for 15-20 minutes, or until the onions have cooled down to room temperature. This cooling step prevents the sour cream from separating or becoming too thin.
- Reserve a few tablespoons of the cooled caramelized onion mixture to use later as a garnish. To the remaining onions in the bowl, add the light sour cream (or Greek yogurt), chopped fresh chives, Worcestershire sauce, fresh thyme leaves, fine sea salt, and freshly-cracked black pepper. Stir all the ingredients thoroughly until they are evenly combined and the dip has a consistent texture.
- Taste the dip and adjust the seasoning as needed. Add more salt and pepper to enhance the flavors, or an additional splash of Worcestershire sauce if you desire more umami depth.
- Serve the dip immediately, garnished with the reserved caramelized onions and an extra sprinkle of fresh chives for color and freshness. Alternatively, cover the bowl and refrigerate the dip for at least 1 hour to allow the flavors to meld and deepen, which often results in an even more delicious dip. The dip can be refrigerated for up to 3 days.

Tools You’ll Need

- Medium mixing bowl
- Measuring spoons and cups
- Sharp knife
- Cutting board
Essential Success Tips
- Patience is key for caramelizing onions. Don't rush the process; the low and slow heat is what brings out their natural sweetness and deep color.
- If your pan starts to burn, a small splash of water (or even broth) can help deglaze the bottom and prevent scorching, incorporating those flavorful browned bits.
- Ensure the caramelized onions are fully cooled before mixing them into the sour cream. Warm onions can cause the dairy to curdle or become watery.
- Taste and adjust seasonings! The amount of salt, pepper, and Worcestershire can vary based on personal preference and the intensity of your caramelized onions.
- Allow the dip to chill for at least an hour before serving; this allows the flavors to fully meld and deepen, creating a more harmonious and delicious dip.
Professional Cooking Secrets
- For an extra layer of complexity, deglaze the pan after caramelizing the onions with a small splash (around 15 ml / 1 tablespoon) of dry sherry or white wine, letting it reduce completely before adding the garlic. This adds a subtle, sophisticated note.
- If you're making a larger batch or want a thicker dip, consider straining the excess liquid from the sour cream (or Greek yogurt) before mixing. Place it in a colander lined with cheesecloth over a bowl in the fridge for an hour or two.
- To achieve an even creamier consistency and bind the dip beautifully, a pinch of cream cheese (about 30 grams / 2 tablespoons), softened, can be whisked into the sour cream before folding in the onions.

Notes
- Storage: The dip can be stored in an airtight container in the refrigerator for up to 3 days. The flavors will continue to deepen over time.
- Variations: For a smoky twist, add a pinch of smoked paprika. For a tangier dip, a squeeze of fresh lemon juice can be added to taste. You can also experiment with different herbs like parsley or dill.
- Serving Suggestions: Serve with sturdy potato chips, pretzel crisps, crudités (carrots, celery, bell peppers), or toasted baguette slices.
Frequently Asked Questions
Can I make this French Onion Dip ahead of time?
Absolutely! This dip actually benefits greatly from being made ahead. Preparing it a few hours, or even a day, in advance allows the flavors to meld and deepen, resulting in an even more delicious and cohesive dip.
What's the best way to caramelize onions without burning them?
The key is low and slow heat. Don't rush the process. Use a heavy-bottomed pan to ensure even heat distribution. If onions start to stick or brown too quickly, reduce the heat and add a tablespoon of water or broth to deglaze the pan and scrape up any flavorful fond.
Can I use plain Greek yogurt instead of sour cream?
Yes, you can! Plain Greek yogurt makes for a lighter version of the dip while still maintaining a creamy texture and tangy flavor. It might be slightly thicker than sour cream, so you might need to adjust the consistency with a splash of milk or water if desired.
