What Kind of Cheese Works Best in Caramelized Onion Dip?

Gruyere is the shining star here. Its rich, slightly nutty flavor complements the sweetness of caramelized onions and melts into a silky, pull-apart texture. You could mix in a touch of mozzarella for stretch or even a bit of Parmesan for a salty bite, but Gruyere remains the backbone of this luxurious dip.

Ingredients for the Caramelized Onion and Gruyere Dip

• Yellow Onions – These are your foundation; their natural sweetness deepens as they slowly caramelize.
• Unsalted Butter – A must for drawing out that golden, buttery flavor in the onions.
• Olive Oil – Helps prevent the butter from burning while adding a fruitier dimension.
• Garlic – Just a touch to sharpen the flavor base.
• Gruyere Cheese – The star cheese: melty, nutty, deeply savory.
• Cream Cheese – Adds body and a lush, creamy mouthfeel.
• Sour Cream – Balances richness with tang and lightens the dip.
• Fresh Thyme – Earthy and aromatic, thyme ties it all together.
• Salt & Pepper – Enhances and rounds out every flavor.

How To Make the Caramelized Onion and Gruyere Dip

Step 1: Caramelize the Onions

In a skillet over medium-low heat, melt butter with olive oil. Add thinly sliced onions and a pinch of salt. Stir occasionally, letting them soften and turn deep golden brown—about 30-40 minutes. Add garlic in the final 5 minutes.

Step 2: Prepare the Cheese Base

In a bowl, combine softened cream cheese, sour cream, shredded Gruyere, salt, pepper, and thyme. Stir until smooth and well combined.

Step 3: Combine and Bake

Stir in the caramelized onions (reserving a few for garnish). Transfer mixture to a baking dish or small cast iron skillet. Top with extra Gruyere and bake at 375°F for 20-25 minutes, or until bubbly and golden.

Step 4: Garnish and Serve

Top with reserved onions and a sprinkle of fresh thyme or parsley. Serve hot with toasted baguette slices, crackers, or sturdy veggies.
