Perfect for dinner parties, game days, or cozy nights in, this dip brings people together around the table. It’s upscale enough for a holiday spread but easy enough for a last-minute get-together. You’ll want to keep this recipe on repeat once you get your first taste.


Why You’ll Love This Caramelized Onion and Gruyere Dip

This dip brings out the natural sweetness of onions with the bold nuttiness of Gruyere. It’s deeply savory, perfectly creamy, and just the right amount of indulgent. Plus, it’s a breeze to prepare ahead of time and reheat before guests arrive.


Can I Use a Different Cheese Besides Gruyere?

Absolutely. While Gruyere provides that iconic melty texture and nutty flavor, you can swap in Swiss cheese, fontina, or even white cheddar for a different twist. Just be sure to use a cheese that melts well and complements the sweet-savory profile of the caramelized onions.


Ingredients for the Caramelized Onion and Gruyere Dip

Each ingredient in this dip has a clear, delicious purpose:

  • Yellow Onions – The star of the show. Slowly caramelized, they bring a deep, natural sweetness that forms the backbone of the flavor.
  • Unsalted Butter – Essential for getting those onions perfectly soft and golden.
  • Gruyere Cheese – Melts like a dream and gives the dip its signature nutty, savory depth.
  • Cream Cheese – Adds body and creaminess, making the texture smooth and scoopable.
  • Sour Cream – For a slight tang that balances the richness.
  • Fresh Thyme – Adds a fresh, herby note that brightens the whole dish.
  • Garlic – A small amount goes a long way to enhance the savory undertones.
  • Salt and Pepper – Brings everything into balance.

How To Make the Caramelized Onion and Gruyere Dip

Step 1: Caramelize the Onions

Start by slicing your onions thinly. Melt butter in a skillet over medium-low heat and cook the onions slowly until deeply golden and fragrant, stirring occasionally. This may take 30-40 minutes but is worth every second.

Step 2: Mix the Cheeses

In a mixing bowl, combine softened cream cheese, sour cream, shredded Gruyere, minced garlic, salt, and pepper. Stir in the fresh thyme and fold in the caramelized onions once cooled slightly.

Step 3: Bake to Perfection

Spread the mixture into an oven-safe dish and bake at 375°F (190°C) for about 20-25 minutes, or until the top is golden and bubbly.

Step 4: Serve Hot

Garnish with extra thyme and serve warm with crusty bread, crackers, or fresh-cut veggies.


How to Serve and Store This Dip

This dip serves about 6 to 8 people as an appetizer. It’s best enjoyed warm, fresh from the oven, but leftovers keep beautifully. Store any remaining dip in an airtight container in the refrigerator for up to 3 days. To reheat, simply warm in the oven or microwave until bubbly again.
