Cook the tortellini according to the package instructions until al dente. Drain and set aside.
In a large skillet, heat olive oil over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant, being careful not to burn it.
Pour in the crushed tomatoes and stir in the dried Italian herbs and red pepper flakes, if using. Let the mixture simmer for about 5 minutes, allowing the flavors to combine.
Reduce the heat to low and add the heavy cream, stirring until it's well blended and heated through.
Add the cooked tortellini to the skillet, gently tossing to coat each piece in the creamy tomato sauce.
Stir in the chopped fresh basil and season with salt and pepper to taste. Allow the dish to cook for another 2-3 minutes to meld the flavors.
Serve immediately, garnished with grated Parmesan cheese and a few extra basil leaves if desired.
