8 oz cream cheese, room temperature
1/2 cup mayonnaise
2 cloves garlic, minced
1 tablespoon fresh thyme leaves

2. Add sliced onions with salt, stirring to coat evenly.
3. Cook 30-35 minutes, stirring every 5 minutes, until deep golden brown.
4. Add garlic and thyme, cook 1 minute more, then cool slightly.
5. Combine cream cheese, mayonnaise, and grated Gruyere in mixing bowl.

You can substitute Emmental or aged Swiss cheese if Gruyere isn’t available.
Make ahead up to 24 hours – store covered and bring to room temperature before baking.
