A creamy truffle pasta built on butter, garlic, cream, and parmesan, with black truffle oil stirred in off the heat so the flavor survives. Six ingredients and about 20 minutes, most of it waiting for pasta water to boil.
Serve immediately, topped with extra parmesan, chopped parsley, and cracked black pepper.
Fresh parsley, chopped (for garnish)
Notes
Truffle oil goes in off the heat. Take the pan off the burner before the oil goes in. The aroma is volatile and heat drives it off within seconds. This is the difference between tasting truffle and tasting cream.
Start with 1 teaspoon and taste. Brands vary a lot in strength. You can add more after tossing, you can't take it out.
Grate the parmesan from a block. Pre-grated is coated with anti-caking agents that stop it melting cleanly, and the sauce comes out grainy.
Reserve a full cup of pasta water. It's what loosens the sauce and helps it cling. Once the pot is drained there's no substitute.
Keep the cream at medium heat. A hard simmer splits a cream sauce and it won't come back.
Watch the garlic. In butter it goes from golden to burnt in about fifteen seconds.
Black truffle oil over white. Black is earthier and stands up to cream. White is more delicate and gets buried here.
Any long pasta works. Linguine, fettuccine, or spaghetti. Cream sauce clings to strands better than it does to short shapes.
To add mushrooms: Slice and brown them in the pan before the butter and garlic. Don't salt until they've released their water and started to color. Adds about 8 minutes.
Storage: Up to 3 days in the fridge. Reheat gently with a splash of cream or milk. The truffle aroma fades by day two, so a small drizzle of fresh oil after reheating brings it back.
