Ingredient Notes
The star of this Caramelized Onion and Gruyere Dip is, of course, the onions. Slowly caramelizing them brings out their natural sweetness and creates that deep golden color and rich flavor.
Gruyere cheese adds a slightly nutty, melty quality that elevates the dip far beyond standard cheese dips. If you can, grate it fresh—it melts better and tastes richer. The combination of cream cheese, sour cream, and mayo creates a smooth, velvety base that ties everything together.
