Fettuccine in Butter and Parmigiano Reggiano Sauce

Introduction

You’re building the sauce from 8 ounces of softened butter and grated aged Parmesan-style cheese, then loosening it with 1/2 cup of starchy pasta water until the fettuccine turns glossy. This is a fast pasta for nights when you want a full dinner in about 25 minutes and don’t need anything more than a pot, a whisk, and good timing.

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) aged Parmesan-style cheese (aged 24 months), grated
• Salt
• 1 pound (450 g) fettuccine egg noodles

Instructions

1. Whisk together the butter and grated Parmesan-style 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 the same ribbon shape with a slightly lighter bite.
• Use spaghetti instead of fettuccine egg noodles if that’s what you have; the sauce will coat it more lightly and feel less rich in each bite.
• Add freshly ground black pepper at the end for a sharper finish that cuts through the butter.
• Stir in a little lemon zest with the pasta water in step 4 if you want a brighter, less heavy final flavor.
• Mix in a small handful of chopped flat-leaf parsley before serving to add freshness and a bit of color without changing the structure of the dish.

Tips for Success

• Make sure the butter is truly at room temperature before step 1, or the cheese mixture won’t turn creamy.
• Grate the aged Parmesan-style cheese finely so it melts into the noodles instead of clumping.
• Don’t forget to reserve 1/2 cup of pasta water before draining; that starch is what turns the butter and cheese into a smooth sauce.
• In step 4, keep the pot warm but not over direct high heat, or the sauce can go greasy instead of glossy.
• Stop adding pasta water when the noodles look glistening and smooth; too much will thin the sauce past the point where it clings.

Storage and Reheating

Store leftovers in an airtight container in the fridge for up to 3 days. This pasta is not a good freezer dish, since the butter-and-cheese sauce tends to separate after thawing.

Reheat it in a skillet over low heat with a small splash of water, stirring until the sauce loosens and coats the noodles again. You can also microwave it in short bursts at 50% power, covered, stirring between bursts so the sauce doesn’t split.

FAQ

Can you use pre-grated cheese?

You can, but it usually gives a rougher sauce because anti-caking agents keep it from melting as smoothly. Freshly grated cheese works better here.

Why did the sauce turn oily instead of smooth?

That usually happens if the noodles cool too much before mixing or if the sauce gets too much direct heat. Vigorous tossing with the reserved pasta water brings it back together.

Can you use another pasta shape?

Yes. Long noodles like tagliatelle or spaghetti work best because they catch the butter-and-cheese sauce evenly.

Can you make this with gluten-free pasta?

Yes, but watch the pasta water closely because some gluten-free noodles release less starch. You may need a bit less water to keep the sauce from getting thin.
