Boil a large pot of salted water.
Add the Buitoni tortellini and cook according to package instructions until they float to the surface, usually 2-3 minutes.
As the tortellini are cooking, warm up some olive oil in a skillet over medium heat. Add minced garlic and sauté until fragrant.
Pour in the heavy cream, whisking constantly until it starts to simmer.
Stir in the grated Parmesan cheese and continue to cook, allowing the sauce to thicken.
Season with salt and pepper to taste.
Using a slotted spoon, transfer the cooked tortellini directly from the boiling water into the creamy sauce.
Gently toss the tortellini in the sauce until they are well coated.
Garnish with chopped fresh parsley.
Serve immediately.
