Make sure you have all of your ingredients prepped and ready to go. This recipe moves fast! Bring a large pot of salted water to a boil. Cook the pasta to al dente according to package instructions. Reserve 1 cup pasta water (don’t forget!), then drain.

Meanwhile, in a large Dutch oven or similar large, deep pan, heat the 2 tablespoons olive oil over medium-high. Squeeze the sausages from their casings into the pot. With a wooden or similar sturdy spoon or spatula (I love my meat chopper), break up the sausage into small pieces and cook until browned and cooked through, about 5 to 8 minutes. If at any point the pan looks dry and the sausage starts to really stick, add a little more oil as needed.

Add the salt, black pepper, red pepper, and garlic and cook, stirring constantly, for 30 seconds.

Pour in the wine, scraping up any bits that have collected on the bottom of the pan. Cook until the wine has reduced by approximately half, about 1 minute.

Reduce the heat to low. Add the white beans, sun-dried tomatoes, pasta, and ½ cup of the reserved pasta water. Heat gently and stir until well combined and the sauce starts to come together, about 1 to 2 minutes. If at any point the pasta looks dry, splash in a little additional pasta water as needed.

Remove the pan from the heat. Add the sun-dried tomato oil, butter, Parmesan, lemon zest (zest the lemon right over the pasta), and lemon juice. Keep stirring until combined and the noodles are coated in a silky sauce.

A few handfuls at a time, stir in the baby spinach until it wilts. Serve topped with additional Parmesan to taste.
