  • 8 oz 225g cream cheese, softened
  • ½ cup sour cream or Greek yogurt
  • 1 ½ cups shredded Gruyere cheese freshly grated
  • 2 tablespoons grated Parmesan cheese optional
  • A few dashes hot sauce optional

Method
 

  1. Caramelize the Onions

  11. Spread the dip mixture into an oven-safe baking dish. Sprinkle remaining ½ cup Gruyere on top.
  12. Bake the Dip
  13. Bake at 375°F (190°C) for 18–20 minutes, or until hot, bubbly, and golden on top.
  14. (Set WPRM Timer: 20 minutes)
  15. Serve Warm
  16. Remove from the oven, cool for 5 minutes, and serve with crackers, bread, veggies, or as part of a charcuterie board.

Notes

Caramelize low and slow for the best onion flavor—don’t rush this step.
Freshly grated Gruyere melts smoother than pre-shredded cheese.
Substitute Gruyere with Swiss, Fontina, or Emmental if needed.
This dip can be prepared ahead: assemble, refrigerate, then bake before serving.
Delicious with crostini, pretzels, crackers, apple slices, or fresh veggies.
Perfect addition to cheese platters, snack boards, and party spreads.
