Bring a large pot of salted water to a boil. Submerge the spinach, kale, and basil for 1 minute, then immediately transfer them to an ice bath using a slotted spoon. This stops the cooking process and keeps the sauce a vibrant green.
2 cups spinach, 2 cups kale, 2 cups fresh basil
Bring that same pot of water back to a boil and cook the pasta according to the package directions. Reserve 1 cup of pasta water to use in your sauce before draining the pasta!
16 ounces pasta
Add the sausage, kosher salt, and crushed red pepper. Cook, breaking the meat into bite-sized pieces, until fully browned. Remove the sausage from the pan and set it aside, leaving the rendered fat in the skillet.
1 tablespoon olive oil, 1 pound Italian sausage, 1 teaspoon crushed red pepper, 1 teaspoon kosher salt
Return the skillet to medium heat (add a splash more olive oil if the pan looks dry). Sauté the diced onion and garlic for 3-5 minutes until the onions are translucent and fragrant.
½ yellow or sweet onion, 2 cloves garlic
To a blender, add the blanched greens, sautéed onion and garlic, cannellini beans, parmesan cheese, olive oil, kosher salt, and 1/3 cup of the reserved pasta water. Blend until completely smooth and vibrant. Taste and adjust salt or red pepper if needed.
2 tablespoons olive oil, ½ cup cannellini beans, 1 cup fresh parmesan cheese, 1 cup pasta water, 2 teaspoons kosher salt
Return the skillet to medium heat. Add the cooked pasta, browned sausage, and the green sauce. Toss well to coat. Pour in the remaining pasta water a little at a time, tossing constantly for 2-3 minutes until the sauce thickens and clings to the pasta.
Garnish with extra parmesan and a pinch of crushed red pepper. Serve warm with crusty bread and enjoy!
