Heat 2 tablespoons of olive oil or butter in a large skillet over medium heat. Add 8 ounces of sliced mushrooms and sauté for 8-10 minutes until browned and tender. Add 2 cloves of minced garlic and cook for an additional minute until fragrant.

Reduce the skillet heat to low and incorporate 8 ounces of softened cream cheese and ½ cup of sour cream into the mushroom mixture. Stir continuously until fully combined.

Mix in ½ cup of shredded mozzarella cheese and ¼ cup of grated Parmesan cheese, stirring until melted and creamy.

Transfer the mixture to an oven-safe baking dish, sprinkle the remaining mozzarella cheese on top, and bake at 375°F (190°C) for 15-20 minutes until bubbly and golden brown.

Garnish with 1 teaspoon of freshly chopped thyme or parsley and serve warm with toasted baguette slices, crispy pita chips, or vegetable sticks.
