Ingredients
Main Components
- 2 tablespoons unsalted butter (room temperature for easier melting)
- 2 cloves garlic, minced (fresh for the best flavor)
- 2 ounces cream cheese (softened for easy blending)
- 1½ cups heavy whipping cream
- ½ cup freshly grated Parmesan cheese (not the shelf-stable kind—fresh is key!)
- ½ teaspoon ground white pepper
- ¼ teaspoon ground nutmeg (optional, but adds warmth)
- Salt, to taste
Expert Tips (Before You Begin)
- Use Fresh Parmesan: Pre-grated Parmesan often contains anti-caking agents that prevent smooth melting.
