Instructions

Caramelize the Onions: In a large skillet over medium heat, melt the butter with olive oil. Add the thinly sliced onions and cook slowly, stirring frequently, until the onions are golden brown and caramelized, about 25-30 minutes. This process develops the rich sweetness essential to the dip.
Combine Cream Cheese and Sour Cream: While the onions cook, in a medium bowl, soften the cream cheese if needed, then mix it together with the sour cream until smooth and creamy to create the dip base.
Add Cheese and Seasonings: Stir in the grated mozzarella and Parmesan cheeses to the cream cheese mixture. Then, add garlic powder, onion powder, black pepper, salt, and dried thyme if using. Mix well to incorporate all flavors.
Mix in Caramelized Onions: Once the onions are caramelized, remove them from heat and let them cool slightly before folding them gently into the creamy cheese mixture, ensuring even distribution for a balanced flavor in every bite.
Bake the Dip: Preheat the oven to 350°F (175°C). Transfer the combined mixture into an oven-safe baking dish. Bake uncovered for about 15-20 minutes until the dip is heated through and bubbly on top.
Garnish and Serve: Remove the dish from oven and garnish with chopped fresh parsley. Serve hot with tortilla chips, crackers, or fresh vegetables for dipping.

Notes

Slowly caramelizing the onions is key to building flavor, so avoid rushing the process with high heat.
Feel free to substitute the mozzarella with a sharper cheese like cheddar if you prefer stronger flavors.
You can prepare the caramelized onions ahead of time and refrigerate to save time on serving day.
Adjust salt to taste, especially if using salted cheeses or serving with salty chips.
