Begin by boiling a large pot of salted water and cook your pasta according to package instructions. Drain and set aside.

In a large skillet, heat olive oil over medium heat. Add the sliced smoked sausage and cook until browned. This should take about 5 minutes.

Toss in the diced onion and minced garlic. Sauté until the onion becomes translucent—about 2-3 minutes.

Stir in the Italian seasoning, allowing the savory aroma to fill your kitchen.

Pour in the heavy cream, bringing the mixture to a gentle simmer. Once it starts bubbling, lower the heat.

Gradually mix in your grated cheese, stirring until melted and combined. Now, taste it! Add salt and pepper as needed.

Add the cooked pasta to the sauce, tossing until evenly coated.

Garnish with freshly chopped parsley and an extra sprinkle of cheese if desired. Dive in and enjoy the creamy goodness!
