Ingredients
List of Ingredients
- 3 large onions, thinly sliced
- 2 tablespoons olive oil
- 1 tablespoon butter
- 1 teaspoon sugar
- 1 cup sour cream
- 1 cup grated Gruyère cheese
- 1/2 cup cream cheese, softened
- 2 cloves garlic, minced
- 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme)
- Salt and pepper to taste
- Fresh parsley, chopped (for garnish)
The star of this dip is the onions. You want them to be sweet and rich. I start with three large onions for a good base. Thinly slice them to help them caramelize evenly. The blend of olive oil and butter adds flavor and richness. A touch of sugar helps the onions turn golden brown.
Next, I use sour cream and cream cheese. They create a smooth and creamy texture. Gruyère cheese adds a nutty flavor that makes this dip special. Don’t forget garlic and thyme; they bring depth and aroma. Season with salt and pepper for balance.
Finally, I top the dip with more Gruyère cheese. This creates a bubbly, golden crust when baked. Fresh parsley adds a nice touch when serving.

Step-by-Step Instructions
Caramelizing the Onions
1. Heating the oil and butter
Start by warming a large skillet over medium heat. Add 2 tablespoons of olive oil and 1 tablespoon of butter. Let them melt together. This mix gives the onions a rich flavor.
2. Adding onions and sugar
Next, add 3 large, thinly sliced onions and 1 teaspoon of sugar to the skillet. Stir well to coat the onions in the oil and butter. The sugar helps the onions caramelize nicely.
3. Cooking time and stirring tips
Cook the onions for about 30 to 40 minutes. Stir them occasionally. If they start to stick, lower the heat a little. You want the onions to turn golden brown and sweet.
Preparing the Dip
1. Mixing sour cream and cream cheese
In a mixing bowl, combine 1 cup of sour cream and 1/2 cup of softened cream cheese. Mix until smooth. This base adds creaminess to the dip.
2. Incorporating caramelized onions and thyme
Once the onions cool slightly, add them to the bowl. Don’t forget to add 2 cloves of minced garlic and 1 teaspoon of fresh thyme leaves. Mix well and add salt and pepper to taste.
Baking the Dip
1. Transferring to baking dish
Transfer the dip mixture into a baking dish. Spread it out evenly. Then, sprinkle 1 cup of grated Gruyère cheese on top.
2. Baking time and temperature
Preheat your oven to 350°F (175°C). Bake the dip for 20 to 25 minutes. Look for it to be hot and bubbly, with a golden-brown top. This step makes it warm and inviting.
Tips & Tricks
Perfecting Caramelization
To get the best caramelized onions, start with medium heat. Too high will burn the onions. Stir the onions every five minutes. This helps them cook evenly. If they stick to the pan, lower the heat. They should turn a nice golden brown in about 30 to 40 minutes. Patience is key here. The slower they cook, the sweeter they get.
Serving Suggestions
Serve the dip warm. It's delightful with sliced baguette, tortilla chips, or fresh veggie sticks. For a fancy touch, sprinkle chopped parsley on top. It adds color and freshness. Arrange everything on a nice platter for a great presentation. Your guests will love it!
Making Ahead
Yes, you can make this dip in advance. Cook the dip and let it cool. Then, store it in the fridge. When you're ready, reheat it in the oven. Cover it with foil to keep it moist. Bake at 350°F for about 15 to 20 minutes. This way, you can enjoy your time with guests.
Pro Tips
- Choose the Right Onions: Sweet onions like Vidalia or Walla Walla work best for caramelizing, as they enhance the sweetness of the dip.
- Low and Slow Cooking: Take your time when caramelizing the onions; cooking them on low heat allows for maximum flavor development and prevents burning.
- Variations on Cheese: While Gruyère is delicious, feel free to mix in other cheeses like fontina or mozzarella for a different flavor profile.
- Serving Suggestions: For added crunch, consider serving with toasted baguette slices or homemade pita chips to elevate the snack experience.
