Fettuccine with Parmigiano Reggiano Butter Sauce

Introduction

Softened butter and 24-month Parmigiano Reggiano are whisked into a thick paste, then loosened with reserved pasta water until the fettuccine turns glossy. You get a rich, fast pasta for a weeknight dinner, but the sauce is at its best when you serve it immediately.

Recipe Details

• Prep Time: 10 minutes
• Cook Time: 15 minutes
• Total Time: 25 minutes
• Servings: 4

Ingredients

• 8 oz (2 sticks / 230 g) of butter, unsalted and softened to room temperature
• ½ pound (230 g) Parmigiano Reggiano cheese (aged 24 months), grated
• Salt
• 1 pound (450 g) fettuccine egg noodles

Instructions

1. Whisk together the butter and grated Parmesan-Reggiano cheese until it is creamy. Both ingredients combined should be on the thick side.
2. Put water to boil in a large pot and cook the noodles until al dente.
3. Drain the noodles and reserve ½ cup of liquid to emulsify your sauce.
4. Put noodles back in the warm pot and stir in the butter and cheese mixture with vigorous turning motion while adding pasta water until the noodles are glistening and smooth.
5. Add salt to taste.
6. Serve immediately.

Variations

• Swap the fettuccine egg noodles for tagliatelle if you want a similar width with a slightly firmer bite.
• Replace part of the Parmigiano Reggiano cheese with Pecorino Romano for a sharper, saltier sauce.
• Use salted butter instead of unsalted butter, then reduce or skip the final salt so the sauce does not get overly seasoned.
• Add freshly ground black pepper at the end if you want a more assertive finish without changing the texture.
• Use fresh fettuccine instead of dried and shorten the boiling time; the finished dish will be softer and a little more delicate.

Tips for Success

• Make sure the butter is truly at room temperature before you whisk it with the cheese, or the mixture will stay lumpy instead of creamy.
• Grate the Parmigiano Reggiano finely so it melts into the noodles more easily in the warm pot.
• Reserve the ½ cup of pasta water before it all drains away; that starchy water is what turns the butter and cheese into a smooth sauce.
• Toss the noodles vigorously as you add the butter and cheese mixture so the sauce coats instead of sitting in clumps.
• Stop adding pasta water when the noodles look glistening and smooth, not watery; the sauce tightens slightly as it sits.

Storage and Reheating

Store leftovers in an airtight container in the fridge for up to 2 days. Do not freeze it; the butter-and-cheese emulsion tends to split and the noodles soften too much.

Reheat in a skillet over low heat with a small splash of water, tossing until the sauce loosens and coats the pasta again. You can also microwave it in short 20-second bursts, covered, with a little water stirred in between, but the texture is usually less smooth than stovetop reheating.

FAQ

Can you use pre-grated Parmesan instead of freshly grated Parmigiano Reggiano?

You can, but the sauce is less likely to turn smooth because packaged grated cheese often contains anti-caking agents. Freshly grated cheese melts and emulsifies better.

Why did the sauce turn greasy instead of glossy?

That usually means the pasta did not get enough reserved pasta water or the cheese-and-butter mixture was not fully incorporated. Tossing in the warm pot, not over aggressive heat, helps keep the emulsion together.

Can you make the butter and cheese mixture ahead of time?

Yes. Mix it up to 1 day ahead, refrigerate it, and let it come back to room temperature before you toss it with the hot noodles.

Can you make this with gluten-free pasta?

Yes, if you use a gluten-free fettuccine-style pasta. Reserve the pasta water as directed, but add it gradually since gluten-free pasta water can behave a little differently.
