Why I Love This French Onion Cheese Dip Recipe

A warm dip in the winter, just in time for New Year’s, is all about the melty cheese. But mixing cheeses together and achieving the correct ratio for the perfect melting texture can be tricky. On top of that, the cheeses need to have flavor and complexity, but not have too much funk that they stick out from all the other cheeses.

This French onion cheese dip is an instant classic! Onions are slowly caramelized until browned, drawing out their sweet flavor. And the mixture of cheeses creates a unique and delicious dip that elevates this from just any ordinary cheese dip to something extra special!

French Onion Cheese Dip Ingredients

  • Sweet onions are slowly sautéed. The key is to do this slowly so the sugars caramelize. The flavor will become lighter and sweeter and the onions will be almost like jam.
  • Butter is sautéed with the onions to help start the caramelization process, but also add a little underlying flavor.
  • Cream cheese is the base of this dip. The sweet, tangy flavor from the cream cheese complements the other cheeses and also adds the perfect creamy texture.
  • Full fat Greek yogurt adds a layer of flavor and helps create additional creamy texture. Full fat is essential so the cheese dip does not separate when heated in the oven.
  • Balsamic vinegar adds sweetness and some acidity to round out the flavors.
  • Garlic powder may seem antiquated, but the powder packs a strong punch. Instead of needing to cook raw garlic, the powder flavor is more mellow and easy to blend into the cheese.
  • Brie cheese is a go-to for baking and is usually wrapped in puff pastry. The baking instantly melts the Brie. Keep the rind on the Brie for added texture.
  • Gruyere cheese is a hard Swiss cheese. Even though it’s a hard cheese, it also melts well and adds a punch of flavor.
  • Parmesan cheese is the salty finish for the dip. Make sure to use authentic Parmesan for the most flavor and the correct texture. No Parmesan powder here!

The full amount of each ingredient can be found in the recipe card below.
