This creamy sausage penne pasta is rich, savory, and far more flavorful than the simple ingredient list suggests. Browning the Italian sausage deeply, giving the onions time to soften and sweeten, and finishing the sauce with parmesan and pasta water creates a silky, comforting dinner that feels special without much extra work.

Instructions
Cook the pastaBring a large pot of well-salted water to a boil and cook the penne until just al dente. Before draining, reserve about 1/2 cup of the pasta water, then drain the pasta and set it aside.
Brown the sausage properlyWhile the pasta cooks, heat a large skillet or Dutch oven over medium heat and add the ground Italian sausage. Let it cook without stirring too much at first so it can develop real browning and crispy edges instead of just turning gray. Break it up as it cooks and let it brown well, about 7–8 minutes. If your sausage is very lean, add a little olive oil.
Cook the onions slowlyAdd the diced onion directly to the skillet with the sausage and cook for 5–7 minutes, stirring occasionally, until the onion is softened and lightly golden. Add the minced garlic and cook for about 30 seconds, just until fragrant. If you have tomato paste, stir it in now and let it cook for about 1 minute until it darkens slightly and smells richer.
Make the creamy sauceLower the heat and pour in the heavy cream, stirring well and scraping up any browned bits from the bottom of the pan. Add both kinds of parmesan and stir until the cheese melts into the sauce. Add a splash of the reserved pasta water and stir until the sauce becomes smooth and silky. Taste before adding salt, since the sausage and parmesan may already provide plenty. Add black pepper and red pepper flakes if desired.
Make the topping (optional)If you’d like the crispy topping, heat a small skillet over medium heat with a little olive oil. Add the breadcrumbs and cook until golden brown, stirring often. Add a little parmesan and garlic during the last 30 seconds, then remove from the heat.
Finish the pastaAdd the cooked penne to the sauce and toss until every piece is coated. Let it sit for a minute or two so the sauce clings to the pasta. Serve hot with extra parmesan on top and the crispy breadcrumbs sprinkled over everything, if using, and some optional fresh parsley or basil.
