Boil a large pot of water, then add a generous pinch of salt followed by the ditalini. Stir well and return to a rapid boil.
12 ounces ditalini or another small pasta shape, kosher salt and black pepper
When the pasta is 2 minutes shy of package directions for al dente, scoop out 1 cup of the cooking water and set it aside, then add peas to the bubbling water. Continue to cook until the pasta is tender, then drain off the water and set the pasta and peas aside together.
1-2 cups peas
In either a small saucepan or the now-empty pasta pot, combine the 1 cup reserved pasta water and 1/3 cup olive oil. Bring the mixture to a rapid boil over medium-high heat. Let it bubble for 4 minutes; this emulsifies the sauce, making it smooth and light.
1/3 cup extra-virgin olive oil
After the sauce bubbles for 4 minutes, reduce heat to medium-low and combine it with the drained pasta and peas. Toss to coat, then stir in the Parmesan.
1 cup grated Parmesan
Let the Parmesan gently melt into the sauce, then serve as desired with more Parmesan, black pepper, lemon juice or zest, and red pepper as desired. Enjoy!
