How to Make 10-Minute Alfredo Sauce

1. Simmer butter and cream: In a large skillet or saucepan, melt ½ cup of unsalted butter over medium-low heat. Pour in 1.5 cups of heavy cream and add the grated garlic. Bring to a gentle, steady simmer (do not boil aggressively), whisking frequently for 3 to 4 minutes until slightly reduced and thickened.
2. Melt the cheese off the heat: Turn off the heat completely or remove skillet from the burner. Sprinkle in the 1.5 cups of freshly grated Parmigiano-Reggiano in three batches, whisking constantly between each addition until completely melted, velvety smooth, and glossy.
3. Season and toss: Whisk in sea salt, cracked black pepper, and a tiny pinch of ground nutmeg. Immediately toss with 1 lb of freshly boiled fettuccine or penne pasta, using 2 to 3 tablespoons of hot starchy pasta water to emulsify the sauce into a restaurant-style cling.

The 3 Non-Negotiables for Ultra-Smooth Alfredo Sauce

1. Grate Your Own Cheese From a Block: Pre-shredded cheese from bags or green shaker cans is coated in cellulose (wood pulp) and potato starch to prevent clumping on store shelves. When melted, these starches cause graininess and grease separation. Freshly grated Parmigiano-Reggiano melts instantly into silk.
2. Remove Pan From Heat Before Adding Cheese: High boiling heat causes dairy proteins in parmesan to seize, separate, and become stringy. Whisking the cheese into the warm butter-cream mixture off the heat guarantees an emulsion that never separates.
3. Save Your Starchy Pasta Water: Never rinse your pasta! When tossing noodles with Alfredo, reserve ½ cup of the cloudy, salted pasta boiling water. Adding a few tablespoons creates a restaurant-style emulsion that binds the rich sauce to the pasta strands.
