Ingredients Method

Ingredients
  

  • 4 tablespoons unsalted butter
  • 3 cloves garlic, finely minced (or 1 teaspoon garlic powder in a pinch)
  • 1 3/4 cups heavy whipping cream
  • 3 ounces cream cheese, cut into small pieces (room temperature if possible)
  • 1 1/4 cups freshly grated Parmesan cheese (preferably Parmigiano-Reggiano)
  • 1/4 teaspoon ground black pepper
  • 1/4 teaspoon fine sea salt, plus more to taste
  • 1/4 teaspoon Italian seasoning or dried parsley (optional)
  • Pinch of grated nutmeg (optional but classic)

Method
 

  1. Melt the butter: Place a medium saucepan over medium heat. Add the butter and let it melt gently without browning.
  2. Sauté the garlic: Stir in the minced garlic and cook for 30–60 seconds until fragrant. Don’t let it brown, or it can taste bitter. If using garlic powder, add it later with the cream.
  3. Add the cream: Pour in the heavy cream and whisk to combine. Bring to a gentle simmer—small bubbles around the edges—then reduce the heat to medium-low. You want it hot, not rapidly boiling.
  4. Whisk in cream cheese: Add the cream cheese pieces. Whisk steadily until the cream cheese melts and the sauce looks smooth and slightly thickened, about 3–4 minutes.
  5. Incorporate Parmesan: Sprinkle in the Parmesan a handful at a time, whisking constantly to prevent clumping. Allow each addition to melt fully before adding more.
  6. Season: Add black pepper, salt, and optional Italian seasoning and nutmeg. Taste and adjust salt to your liking. If you used a saltier Parmesan, you may need less salt.
  7. Adjust consistency: If the sauce is too thick, whisk in 1–2 tablespoons of cream or a splash of unsweetened almond milk until it’s silky. If too thin, simmer on low for 2–3 minutes, whisking, until it coats the back of a spoon.
  8. Serve: Remove from heat. Toss with zoodles, spaghetti squash, chicken, shrimp, or steamed broccoli. Serve immediately for the creamiest texture.
