Instructions

1
Bring a large pot of water to a boil and season generously with salt.
2
Add the linguine to the boiling water and cook until slightly al dente (a little underdone).
3
While the pasta is cooking, finely grate the Parmesan cheese.
4
In a large skillet over medium heat, melt the butter.
5
Once the butter is melted, add a ladleful (about 1/2 cup) of the starchy pasta water to the skillet. This will create an emulsion and prevent the butter from browning.
6
Using tongs, transfer the al dente pasta directly from the pot to the skillet. Be sure to reserve the remaining pasta water.
7
Begin adding the grated Parmesan cheese to the pasta in increments, tossing and shaking the pan continuously to melt the cheese and form a creamy sauce.
8
Continue tossing until the sauce is fully emulsified and coats the pasta beautifully.
9
Serve the pasta immediately in a bowl and garnish with additional freshly grated Parmesan cheese.

Tips & Notes

Pro tips

Reserve pasta water before draining—the starch is essential for emulsification. Add it gradually off heat, whisking constantly.
Use freshly grated Parmigiano-Reggiano and grate it fine; pre-grated cheese contains anti-caking agents that prevent smooth melting.
Work quickly once pasta is cooked—toss hot pasta with the butter-cheese mixture off heat to create the emulsion without breaking it.
Taste for salt early; Parmesan is salty, so you may need less than expected. Finish with freshly cracked black pepper and extra cheese.

Substitutions

Linguine → spaghetti or fettuccine (no change to technique)
Parmigiano-Reggiano → Grana Padano (similar melting point and flavor)
Unsalted butter → salted butter (reduce added salt by half)

Storage & make-ahead

Alfredo does not store or reheat well; make fresh to order. Leftover pasta can refrigerate up to 1 day but will thicken—reheat gently with splash of pasta water.

Common Questions

Why doesn't this Alfredo use cream?

Traditional Italian Alfredo relies on the starch in pasta water and fat from butter and Parmesan to create an emulsion. Cream is a modern American addition that masks the cheese flavor.

What type of Parmesan should I use?

Freshly grated Parmigiano-Reggiano works best; avoid pre-grated cheese with cellulose, which prevents smooth melting and emulsification.

How do I keep the sauce from breaking or becoming greasy?

Work off heat, add pasta water gradually to reach proper consistency, and toss gently but constantly. Temperature control is key—keep the pan warm but not hot enough to separate the butter.
