I love a good party dip that tastes gourmet but comes together with pantry staples. This French onion dip deepens simple flavors with slowly caramelized onions and rich, tangy dairy for a crowd-pleaser every time. I’ve made it dozens of times for game nights and family get-togethers — the slow-cooked onions are worth the wait.
Why Make This Recipe

- Versatile for snacks, sandwiches, and party platters — everyone recognizes and loves it.
- Makes-ahead friendly: flavors improve after a few hours in the fridge.
- Personal insight: I love this recipe because caramelizing transforms cheap onions into something complex and luxurious.
Recipe Overview
- Prep time: 10 minutes (slicing onions and softening cream cheese)
- Cook time: 35–40 minutes (caramelizing onions on stovetop)
- Total time: 45–55 minutes (including cooling/chilling)

- Difficulty: Easy–Medium (requires attention while caramelizing)
- Method: Stovetop slow-caramelize onions, then mix with sour cream, mayo, and seasoning; chill.
My Experience Making This Recipe
When I tested this, the biggest discovery was patience: low-and-slow caramelization yields a sweeter, more balanced dip. I also learned that deglazing the pan with a splash of balsamic or water lifts up every browned bit for extra depth.
How to Make the French Onion Dip
Begin by thinly slicing 2 large yellow onions (about 600 g). Cook them in a heavy-bottomed 10-inch skillet with 2 tbsp unsalted butter and 1 tbsp olive oil over medium-low heat, stirring every few minutes until deeply golden — about 35–40 minutes. Deglaze with 1 tbsp balsamic vinegar (or 2 tbsp water) at the end, then let the onions cool.
In a bowl, whisk together 1 cup (240 g) sour cream, 1/2 cup (120 g) mayonnaise, 4 oz (113 g) softened cream cheese, 1 tsp Worcestershire sauce, 1/2 tsp garlic powder, 1/2 tsp onion powder, and salt + black pepper to taste. Fold in 1–1.5 cups cooled caramelized onions. Chill at least 2 hours (overnight ideal) to let flavors marry. Garnish with chopped chives before serving.
Equipment note: use a heavy skillet (cast iron or stainless) for even browning and a sharp knife or mandoline for even slices.
Expert Tips for Success
- Keep heat at medium-low — if onions brown too fast, lower the heat to prevent bitterness.
- Use a heavy skillet to distribute heat evenly; a thin pan burns the edges.
- Stir every 4–6 minutes early on, then more frequently as moisture evaporates to avoid sticking.
- Deglaze the pan with balsamic or a little water to capture fond — that’s where a lot of flavor lives.
- Chill the dip for at least 2 hours so the dairy absorbs onion flavor; overnight is best.
How to Serve the Dip
- Serve with sturdy kettle chips, toasted baguette slices, or crisp vegetable sticks.
- Spoon onto a warm sandwich or burger as a flavor-packed spread.
- For parties, set in a shallow bowl, drizzle a little olive oil, and top with fresh chives.
- Pair with warm bread and a quality bread dipping oil for a luxe snack pairing.
Storage and Reheating Guide
Store in an airtight container in the refrigerator for up to 5 days; use a shallow container to cool quickly. Freezing is possible for up to 2 months, but texture may change — thaw overnight in the fridge and whisk to recombine. To serve warmed, bring to room temperature, then gently reheat in a saucepan over very low heat, stirring; don’t boil, as dairy can separate.
Recipe Variations
- Lighter: swap half the sour cream for plain Greek yogurt for tang and protein.
- Dairy-free: use vegan sour cream + vegan mayo and a vegan cream cheese alternative.
- Cheesy: fold in 1/2 cup grated Gruyère or Parmesan for a richer dip.
- Spicy: add 1–2 tsp sriracha or a pinch of cayenne for heat.
Nutritional Highlights
- Good source of calcium from sour cream and cream cheese; provides a satisfying, protein-containing snack when paired with vegetables.
- Higher in fat — portion control matters (2 tbsp per serving recommended).
- Allergen info: contains dairy and mayonnaise (may contain eggs); substitute vegan products for dairy-free or egg-free needs. Check Worcestershire sauce for anchovies if avoiding fish.
Troubleshooting Common Issues
- Onions burned or bitter: reduce heat immediately, add a splash of water, and scrape browned bits gently; start again over lower heat.
- Dip too thin: add 2–4 tbsp softened cream cheese or more sour cream and chill to thicken.
- Onion flavor too raw/sharp: cook onions longer until deeply brown and slightly sticky; raw-sounding onions mean under-caramelization.
Frequently Asked Questions
Q: Can I make caramelized onions faster?
A: You can increase heat slightly, add 1 tsp baking soda, and stir more frequently to speed browning, but you risk losing depth and developing a slightly mushy texture. For best flavor, plan 35–40 minutes at medium-low heat.
Q: How long will this dip keep in the fridge?
A: Stored in an airtight container, it keeps well for up to 5 days. Always smell and taste before serving; if anything off or mold appears, discard.
Q: Can I use pre-made caramelized onions or store-bought caramelized onion jam?
A: Yes—use about 1.5 cups of pre-made caramelized onions or 3/4 cup jam and adjust salt/sweetness. Taste and balance with lemon juice or vinegar if the store-bought product is very sweet.
Q: Is it safe to freeze dairy dips?
A: You can freeze this dip, but expect some separation. Thaw slowly in the fridge and whisk or blend briefly to restore texture. For best quality, freeze in small portions and use within 2 months.
