01 - Preheat oven to 375°F. Lightly grease a 1 to 1.5-quart baking dish with cooking spray or butter.
02 - Heat olive oil in a medium skillet over medium heat. Add minced garlic and cook for 1–2 minutes until fragrant and pale gold, taking care not to brown or burn.
03 - In a large mixing bowl, beat softened cream cheese until smooth. Add ricotta, 1 cup mozzarella, Parmesan, and sour cream. Mix until fully incorporated and creamy.
04 - Fold in sautéed garlic, basil, oregano, red pepper flakes, black pepper, and salt. Stir until evenly distributed throughout the cheese base.
05 - Transfer mixture to prepared baking dish, spreading into an even layer with a spatula. Top with remaining 1/2 cup mozzarella, covering surface completely.
06 - Bake for 20–25 minutes until dip is bubbly around edges and cheese topping is golden brown. If deeper color is desired, broil for 1–2 minutes at the end.
07 - Remove from oven and let rest for 5 minutes to set. Sprinkle with fresh parsley just before serving.
08 - Serve immediately while hot and bubbly. Accompany with toasted baguette slices, crusty bread, or crackers for dipping.
