Cook the cheese tortellini according to package instructions. Drain and set aside.
In a large skillet, heat the olive oil over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant.
Add the shrimp to the skillet and season with salt, pepper, and Italian seasoning. Cook for 2-3 minutes on each side until the shrimp turn pink and are cooked through. Remove the shrimp from the skillet and set aside.
In the same skillet, pour in the heavy cream and bring to a simmer. Stir in the grated Parmesan cheese until melted and smooth.
Add the cooked tortellini and shrimp back into the skillet, tossing to coat everything in the creamy sauce. Cook for an additional 2-3 minutes to heat through.
Serve immediately, garnished with fresh parsley.
