Instructions

Caramelize the Onions:
- Heat butter and olive oil in a large skillet over medium heat.
- Add the sliced onions and salt, stirring to coat.
- Cook for 30-40 minutes, stirring occasionally, until onions are deep golden brown and jammy. Reduce heat if they begin to burn.
- Stir in sugar (if using) and balsamic vinegar. Cook for another 2-3 minutes until the liquid is absorbed. Remove from heat.
Prepare the Dip Mixture:
- Preheat your oven to 375°F (190°C).
- In a large bowl, combine cream cheese, sour cream, mayonnaise, garlic powder, black pepper, and thyme. Mix until smooth.
- Fold in half of the shredded Gruyere and the caramelized onions (reserve some for topping, if desired).
Assemble and Bake:
- Transfer the mixture to an oven-safe dish.
- Sprinkle the remaining Gruyere on top.
- Bake for 20-25 minutes, or until the top is bubbly and golden brown.
Serve:
- Garnish with fresh thyme and the reserved caramelized onions.
- Serve warm with crackers, baguette slices, or fresh vegetables.

Notes

For a twist, try adding crispy bacon bits to the dip mixture before baking.
Make this dip ahead by assembling it in the dish, covering it tightly, and refrigerating for up to 2 days. Bake when ready to serve.
