In a large pot, bring salted water to a boil. Add the pasta and cook according to package instructions until al dente. Reserve ½ cup of pasta water, then drain the rest and set aside.
In a large skillet, heat the olive oil over medium heat. Add the sliced smoked sausages and cook until browned and heated through, about 5 minutes.
Stir in the minced garlic and chopped spinach. Sauté for another 2-3 minutes until the spinach is wilted and fragrant.
Pour in the heavy cream and bring to a gentle simmer. Add the Parmesan cheese and smoked paprika, stirring to combine and allowing the cheese to melt and thicken the sauce. If it's too thick, add a bit of the reserved pasta water to reach desired consistency.
Add the drained pasta to the skillet and toss to coat with the creamy sausage sauce. Season with salt and pepper to taste.
Plate the creamy pasta and garnish with fresh parsley or basil if desired.
Notes
For a lighter option, use chicken or turkey-based sausages.
