Bring a large pot of salted water to boil and cook ravioli according to package directions, then drain and set aside.
While pasta cooks, melt butter in a large skillet over medium heat and sauté garlic for 1 minute until fragrant.
Add vodka to the skillet and let it simmer for 2-3 minutes to cook off the alcohol.
Stir in crushed tomatoes, heavy cream, red pepper flakes, and salt, then simmer for 5-7 minutes until sauce thickens slightly.
Add cooked ravioli to the sauce and gently toss to coat.
Remove from heat, stir in fresh basil, and serve topped with Parmesan cheese.
