Ingredients
Scale
(Serves 4)
- 12 oz (340g) penne pasta
- ½ cup (1 stick / 115g) unsalted butter
- 1½ cups heavy cream
- 1½ cups freshly grated Parmesan cheese (plus extra for serving)
- 2 garlic cloves, minced
- ¼ tsp ground nutmeg (optional but classic)
- Salt & black pepper to taste
- Optional: pinch of red pepper flakes, fresh parsley
Instructions
- Cook pasta: Boil penne in salted water until al dente. Reserve ½ cup pasta water before draining.
- Make sauce: In a large skillet, melt butter over medium heat. Add garlic; cook 30 seconds until fragrant (don’t brown!).
- Simmer cream: Pour in heavy cream; bring to a gentle simmer. Cook 2–3 minutes, stirring occasionally.
- Finish Alfredo: Reduce heat to low. Gradually whisk in Parmesan until melted and smooth. Stir in nutmeg, salt, and pepper.
- Combine: Add drained pasta to sauce. Toss to coat, adding reserved pasta water as needed to loosen.
- Garnish with extra Parmesan, black pepper, red pepper flakes, and fresh parsley.
💡 Pro Tips:
– Use real Parmigiano-Reggiano for best flavor and meltability.
– For extra silkiness, stir in 2 tbsp cream cheese with the Parmesan!
– Add grilled chicken, shrimp, or sautéed mushrooms for a heartier meal.
