Instant Pot Rigatoni All’Amatriciana

2 T. extra-virgin olive oil. plus more for drizzling

4 ounces pancetta or bacon, diced

1 onion, diced

3 garlic cloves, finely grated or minced

1/2 tsp. crushed red pepper flakes

1/2 tsp. freshly ground black pepper, plus more for serving

1 28-ounce can whole peeled tomatoes with their juices Kosher salt

8 ounces rigatoni

1/2 C. grated pecorino cheese, plus more for serving

 

Using the sauté function, heat the oil and pancetta in the pressure cooker pot. Cook, stirring frequently, until the pancetta is browned and crisp and the fat has rendered, about 5 minutes. Stir in the onion and cook until soft, 3 to 4 minutes. Stir in the garlic, red pepper flakes, and black pepper and cook for 1 minute. Use your hands to crush the whole tomatoes directly into the pot. Make sure to add all the juices from the can. Use a spatula to scrape up the browned bits on the bottom of the pot. Taste the sauce at this point and add salt to taste. Stir in the pasta and 1/2 C. water. Lock the lid into place and cook on high pressure for 6 minutes. Manually release the pressure. Stir in the pecorino. If the pasta is too al dente, cover the pot with the lid (but don’t lock it on), and let it sit for 5 minutes; the pasta mil cook a little more in the residual heat of the pot. Otherwise, serve immediately, with more pecorino, olive oil, and black pepper on top.
