Ingredients 1x2x3x

• 1 cup heavy cream (avoid light cream or half-and-half for best texture)
• 1/2 cup unsalted butter (1 stick)
• 1–2 cloves garlic, finely minced (or 1/2 teaspoon garlic paste)
• 1 1/2 cups freshly grated Parmesan cheese (Parmigiano-Reggiano preferred)
• 1/2 cup grated Romano cheese (optional but boosts that restaurant flavor)
• Salt to taste (start with 1/4 teaspoon and adjust)
• Freshly ground black pepper to taste
• Pinch of nutmeg (optional; adds warmth and depth)
• Cooked pasta of choice (fettuccine is classic)
• Chopped parsley for garnish (optional)

Method

1. Warm the dairy base: In a medium saucepan over low to medium-low heat, melt the butter. Add the heavy cream and whisk to combine. Let it warm gently until steam rises, 3–5 minutes. Do not boil.
2. Bloom the garlic: Stir in the minced garlic and cook for 30–60 seconds, just until fragrant. Keep the heat gentle so the garlic doesn’t brown.
3. Add the cheeses gradually: Reduce the heat to low. Sprinkle in the Parmesan (and Romano, if using) a small handful at a time, whisking continuously. Let each addition melt fully before adding more.
4. Season smartly: Add a pinch of salt, a few grinds of black pepper, and a small pinch of nutmeg. Taste and adjust—Parmesan is salty, so you may need less salt than you think.
5. Find the right texture: If the sauce seems too thick, whisk in 1–2 tablespoons of warm pasta water or a splash more cream. If too thin, let it gently simmer for another minute, whisking, until it lightly coats the back of a spoon.
6. Toss with pasta: Add cooked, hot pasta directly to the pan and toss until every strand is glossy and coated. The sauce will cling better to hot pasta.
7. Finish and serve: Garnish with parsley and a touch more Parmesan. Serve immediately while warm and silky.

Notes

• Refrigerator: Store leftover sauce in an airtight container for up to 3 days. It will thicken when cold.
• Reheating: Warm over low heat with a splash of cream or milk, whisking until smooth. Avoid high heat to prevent separation.
• Freezing: Not ideal. Dairy-based sauces can split when thawed, causing a grainy texture.
• Make-ahead tip: You can grate the cheese and measure ingredients in advance. For best texture, cook the sauce fresh right before serving.
