In a large pot of salted, boiling water, cook the pasta according to the package instructions.
While the pasta cooks, heat the olive oil in a large, shallow saucepan over medium-high heat. Add the sausage and cook, stirring occasionally, until golden brown on all sides, approximately 5 – 7 minutes. Add the minced garlic and cook for an additional 30 seconds, stirring to ensure the garlic does not burn. Add the cream and lower the heat to a gentle simmer. Simmer until reduced slightly, about 4 minutes. Stir in the parmesan cheese and pepper. Add the cooked pasta directly from the cooking water to the sauce. Stir in the spinach and cook over low heat until the spinach has started to wilt, about 2 – 3 minutes. If you find the sauce is too thick, stir in a touch of the pasta water to loosen it up.
Serve immediately, family-style.
