1 pound mild Italian sausage, casing removed

3 tablespoons olive oil

4 cloves garlic, thinly sliced

8 ounces spaghetti, broken in half

One 28-ounce can tomato puree, preferably San Marzano

2 sprigs basil

Pinch crushed red pepper flakes

Kosher salt

1/4 cup freshly grated Parmesan (about .75 ounce), plus more for serving


Special equipment:
a 6- or 8-quart Instant Pot® multi-cooker
  1. Roll the sausage into 16 balls (each about 1 ounce and 1 inch in diameter). Set a 6- or 8-quart Instant Pot® to high saute (see Cook's Note). Add the olive oil to the pot; once it's shimmering, add the meatballs and cook until lightly browned on one side, about 2 minutes. Flip the meatballs and add the garlic. Cook until meatballs are lightly browned on the other side and the garlic is tender, 1 to 2 minutes more. Lay the spaghetti on top of the meatballs, then add the tomato puree, 2 cups of water, basil, red pepper flakes and 2 teaspoons salt. Stir gently, making sure all the spaghetti is submerged in the sauce.
  2. Follow the manufacturer's guide for locking the lid and preparing to cook. Set to pressure cook on high for 6 minutes. After the pressure-cook cycle is complete, follow the manufacturer's guide for quick release and wait until the quick-release cycle is complete (this should take about 2 minutes). Being careful of any remaining steam, unlock and remove the lid, then stir in the Parmesan. Serve with another sprinkle of grated Parmesan on top. The pasta sauce will thicken as it sits and cools.
