A quick one-pan pasta with Italian sausage, wilted spinach, and a simple tomato-Parmesan sauce. Ready in about 25 minutes and perfect for busy weeknights.
Bring a large pot of salted water to a boil and cook pasta 1–2 minutes less than package directions. Reserve 1/2 cup pasta water, then drain.
Heat olive oil in a large skillet over medium-high heat. Add sausage, breaking into pieces, and cook until browned, about 5–7 minutes. Transfer to a bowl and set aside.
In the same skillet, add chopped onion and a pinch of salt. Cook 3–4 minutes until translucent. Add garlic and red pepper flakes; cook 30 seconds until fragrant.
Add crushed tomatoes and broth, stir in oregano, and bring to a gentle simmer. Scrape up browned bits from the pan for extra flavor.
Return sausage to the skillet, add the partially cooked pasta and spinach. Toss until spinach wilts. Stir in Parmesan and add reserved pasta water a splash at a time until sauce is the desired consistency. Season with salt and pepper.
Top with extra Parmesan and fresh basil if desired. Serve hot.
Notes
Swap in turkey or chicken sausage for a leaner option.
Use gluten-free pasta if needed and adjust cook time.
Add mushrooms or sun-dried tomatoes for extra flavor.
Reserve pasta water to loosen the sauce as needed.
