Why You’ll Love This Caramelized Onion and Gruyere Dip

This dip delivers gourmet flavor with minimal effort. Caramelizing onions might take a bit of time, but the payoff is huge in taste. Gruyere cheese brings a rich, nutty melt that’s irresistible when paired with sweet onions. Plus, everything comes together in one baking dish, which means fewer dishes and maximum flavor. It’s comfort food with a touch of elegance, ideal for entertaining or just spoiling yourself a bit.

What Kind of Onion Should I Use for Caramelized Onion Dip?

Yellow onions are the best pick for caramelized onion dip. They have the right balance of natural sugars and mellow sharpness that turns perfectly sweet and jammy as they cook down. White onions can work in a pinch, but yellow delivers that deep caramel flavor you want. Avoid red onions here—they don’t quite caramelize the same way and may turn bitter.

Ingredients for the Caramelized Onion and Gruyere Dip

This recipe is all about rich flavor and creamy texture. Each ingredient plays a key role in layering the savory-sweet balance. Here’s what you’ll need:

• Yellow onions
• Unsalted butter
• Olive oil
• Salt
• Black pepper
• Fresh thyme
• Garlic
• Gruyere cheese
• Cream cheese
• Sour cream
• Mayonnaise

The combination of yellow onions slowly caramelized in butter and olive oil sets a deeply sweet and savory base. A touch of thyme and garlic enhances that warmth, while Gruyere cheese melts into the mix for a sophisticated, nutty finish. The trio of cream cheese, sour cream, and mayonnaise gives it the ultra-creamy texture we crave in a hot dip.

How To Make the Caramelized Onion and Gruyere Dip

Step 1: Caramelize the Onions

In a large skillet over medium heat, melt butter and olive oil together. Add thinly sliced yellow onions and a pinch of salt. Cook slowly, stirring occasionally, for about 30 to 40 minutes until they turn golden brown and jammy. Stir in minced garlic and thyme in the last few minutes.

Step 2: Mix the Dip Base

In a large bowl, combine softened cream cheese, sour cream, and mayonnaise. Mix until smooth and fluffy. Fold in the shredded Gruyere cheese.

Step 3: Combine and Bake

Add the caramelized onion mixture to the cheese base and stir well. Transfer everything to an oven-safe dish, smoothing out the top. Bake at 375°F for about 20 minutes until bubbling and golden on top.

Step 4: Serve Warm

Serve the dip straight from the oven with toasted baguette slices, crackers, or fresh veggies. It’s best enjoyed hot and melty.

How to Serve and Store Caramelized Onion and Gruyere Dip

This dip is rich and satisfying, so it’s perfect as an appetizer that feeds 6 to 8 people comfortably. Serve it in the baking dish to keep it warm longer, and garnish with a few extra thyme leaves for a fresh touch.

Leftovers can be stored in an airtight container in the fridge for up to 3 days. To reheat, pop it back into a baking dish and warm at 350°F until heated through. It may even be better the next day as the flavors settle in.
