Bring a large pot of salted water to a boil and cook the ditalini pasta according to the package instructions until al dente. Drain and set aside.
While the pasta cooks, heat olive oil in a large skillet over medium heat. Add minced garlic and sauté for 30 seconds until fragrant.
Pour in heavy cream and vegetable broth, stirring to combine. Let it simmer for 2-3 minutes until slightly thickened.
Add Parmesan cheese, red pepper flakes, salt, and black pepper. Stir until the cheese melts smoothly into the sauce.
Toss the cooked ditalini pasta into the sauce, stirring until evenly coated.
Remove from heat, garnish with fresh parsley, and serve hot with extra Parmesan on top.
