In a large pot, heat the olive oil over medium heat. Add the minced garlic and sauté for about 1-2 minutes until fragrant but not browned.
Add the orzo pasta to the pot and stir it with the garlic for another minute to gently toast it.
Pour in the vegetable broth and bring the mixture to a boil. Once boiling, reduce the heat to low, cover, and let it simmer for about 10-12 minutes or until the orzo is al dente. Stir occasionally to prevent sticking.
Once the orzo is cooked, remove the pot from heat and stir in the heavy cream, grated Parmesan cheese, Italian seasoning, and red pepper flakes (if using). Mix well until the cheese is melted and the sauce is creamy.
Season with salt and pepper to taste. Let it sit for a couple of minutes to thicken slightly.
Before serving, garnish with freshly chopped parsley to add a pop of color and freshness.
Notes
Add more red pepper flakes for extra heat if desired.
