Ingredients
- 28 grams (2 tablespoons) unsalted butter
- 2 large onions (approximately 500-600 grams), finely chopped
- 5 grams (1 teaspoon) fine sea salt
- 2 grams (1/2 teaspoon) freshly ground black pepper
- 4 grams (1 teaspoon) granulated sugar (optional, for deeper caramelization)
- 240 milliliters (1 cup) full-fat sour cream
- 120 milliliters (1/2 cup) good quality mayonnaise
- 15 milliliters (1 tablespoon) Worcestershire sauce
- 3 grams (1 teaspoon) garlic powder
- 3 grams (1 teaspoon) onion powder
- 10 grams (2 tablespoons) fresh chives, finely chopped, for garnishing
- Pinch of smoked paprika or grated Parmesan cheese, for optional garnishing
Instructions
- In a large, heavy-bottomed skillet, melt 28 grams (2 tablespoons) of butter over medium heat until it shimmers. Add the 2 large finely chopped onions, ensuring they are spread evenly. Season generously with 5 grams (1 teaspoon) of salt and 2 grams (1/2 teaspoon) of black pepper. If desired, sprinkle in 4 grams (1 teaspoon) of sugar to aid in caramelization. Stir well to coat the onions evenly.
- Cook the onions patiently for 20-25 minutes, stirring occasionally to prevent sticking and ensure even browning. The key here is low and slow, allowing the onions to soften, release their moisture, and transform into a deep, golden-brown, sweet, and jammy consistency. This rich caramelization is the heart of the dip's flavor.
- While the onions are undergoing their delightful transformation, prepare the creamy base. In a large mixing bowl, combine 240 milliliters (1 cup) of sour cream, 120 milliliters (1/2 cup) of mayonnaise, 15 milliliters (1 tablespoon) of Worcestershire sauce, 3 grams (1 teaspoon) of garlic powder, and 3 grams (1 teaspoon) of onion powder. Whisk these ingredients together thoroughly until the mixture is completely smooth and well combined.
- Once the caramelized onions have achieved their desired rich color and tenderness, remove them from the heat and allow them to cool completely. Cooling is crucial to prevent the warm onions from separating the dairy components of the dip. Once cool, gently fold the caramelized onions into the prepared sour cream and mayonnaise mixture using a spatula. Mix until the onions are evenly distributed throughout the creamy base, ensuring every bite will be bursting with flavor.
- Transfer the creamy French onion dip into an airtight container. Refrigerate for a minimum of 1 hour, or ideally for 2-4 hours, to allow the complex flavors to fully meld and deepen. This chilling period is essential for achieving the best taste and texture.
- When you are ready to serve, give the dip a final stir. Garnish generously with freshly chopped chives for a bright, fresh counterpoint. For an extra layer of flavor and visual appeal, consider a light sprinkle of smoked paprika or finely grated Parmesan cheese. Serve alongside your favorite sturdy potato chips, crisp vegetable sticks, or toasted baguette slices and enjoy this irresistibly rich delight!

Essential Success Tips
- Patience is key for caramelizing onions: Don't rush the process. Low and slow heat ensures deep sweetness without burning.
- Finely chop the onions: Smaller pieces will caramelize more evenly and integrate better into the dip's texture.
- Allow onions to cool completely: Adding warm onions to the sour cream mixture can cause it to separate or become watery.
- Chill thoroughly: The flavors truly develop and meld after at least an hour in the refrigerator, making it taste even better.
- Taste and adjust: Before serving, taste the dip and adjust salt, pepper, or even a touch more Worcestershire to your preference.
Professional Cooking Secrets
- Deglaze the pan with a splash of dry white wine or a few drops of balsamic vinegar after caramelizing the onions to capture all the flavorful fond, adding another layer of complexity to your dip.
- For an extra layer of umami, try adding a tiny pinch of MSG (monosodium glutamate) or a very finely minced anchovy fillet (it disappears into the dip, leaving only savory depth, not fishiness) to the onions as they caramelize.
- Consider incorporating a small amount of roasted garlic paste into the sour cream base alongside the garlic powder for a more profound and aromatic garlic essence.

Notes
- Storage: Store leftover French onion dip in an airtight container in the refrigerator for up to 3-4 days. The flavors often improve with time.
- Serving Suggestion: While potato chips are classic, consider serving with sturdy crudités like carrot sticks, celery, bell pepper strips, or even toasted sourdough bread slices for a gourmet touch.
- Variations: For a smoky twist, use smoked butter or add a tiny pinch of smoked paprika to the onions as they cook. For a touch of heat, a dash of cayenne pepper can be added to the creamy base.
Frequently Asked Questions
Can I make French onion dip ahead of time?
Absolutely! This dip is fantastic for making ahead. In fact, refrigerating it for several hours or even overnight allows the flavors to meld beautifully, making it taste even better.
Why did my caramelized onions burn?
Caramelizing onions requires patience and medium-low heat. If your heat is too high, the onions will brown too quickly without fully softening or developing their deep sweetness, leading to burning. Stirring occasionally also helps prevent hot spots.
What kind of dippers are best with this dip?
The classic pairing is sturdy, ridged potato chips that can scoop up the creamy goodness. However, it's also delicious with a variety of dippers such as vegetable sticks (carrots, celery, bell peppers), pretzels, toasted baguette slices, or even robust crackers.
