Mark Bittman: Spaghetti with Butter and Parmesan (Plus 10 Easy Additions)

A jumping-off point for many creamy sauces-including the beloved fettuccine Alfredo-and one of the recipes that demonstrates the value of water in pasta sauces: You can use as little as 1/2 stick of butter here and still make a credible sauce, as long as you thin it slightly with the pasta-cooking water. Of course, within limits, more butter is better. From How to Cook Everything.

Spaghetti with Butter and Parmesan

Makes: About 4 servings
Time: 30 minutes

Salt and freshly ground black pepper
4 to 6 tablespoons (1/2 to 3/4 stick) butter
1 pound long pasta, like linguine or spaghetti, or any other pasta
1 cup freshly grated Parmesan cheese, or more to taste

1. Bring a large pot of water to a boil and salt it. Meanwhile, bring the butter to room temperature (you can soften it in a microwave, but don't melt it). Put it in a warm bowl.
2. Cook the pasta until tender but not mushy; drain it, reserving some of the cooking water. Toss the pasta with the butter, adding a little of the water if necessary to thin the sauce. Toss with the Parmesan, sprinkle with salt and pepper, and serve immediately, passing additional Parmesan at the table.

Pasta with Butter, Sage, and Parmesan. A classic when made with browned butter, almost as good with olive oil: Heat 4 or more tablespoons butter with 20 or 30 fresh sage leaves over medium heat for about 3 minutes; the butter should brown and the sage sizzle. Toss the cooked pasta with the butter, sage, and Parmesan, thinning the sauce with pasta-cooking liquid if necessary.

Pasta with Butter, Parmesan, Cream, and Vegetables. With just enough cream to lightly coat the pasta: Use 4 tablespoons (1/2 stick) butter. In Step 1, when the butter has reached room temperature, whisk in 1/2 cup heavy cream. Proceed with the recipe, adding up to 1 cup peas (fresh or thawed frozen) or cooked and chopped spinach, asparagus, or other tender cooked vegetables at the last moment.

Pasta with Butter, Parmesan, and Italian Ham. Cut about 6 ounces pancetta, coppa, or prosciutto into 1/4-inch dice. Put 2 tablespoons of the butter and the meat in a skillet over medium-high heat and cook until the meat is lightly crisped, about 5 minutes. Add this to the warm bowl with the remaining 2 tablespoons butter and proceed with the recipe.

Fettuccine Alfredo. Reduce the butter to 2 tablespoons and melt it gently. Use fettuccine. While the pasta cooks, whisk 2 eggs with 1/2 cup heavy cream and 1 cup grated Parmesan in a warmed bowl. Sprinkle with pepper. When the pasta is cooked, toss it with the cheese-egg-cream mixture, adding a little of the cooking water if necessary to keep the mixture moist. Drizzle with the butter, toss well, and serve immediately.
