01 - Bring a large pot of salted water to a boil. Add orzo pasta and cook until al dente, 7 to 8 minutes. Drain well and set aside.
02 - In a large skillet set over medium heat, melt the unsalted butter. Add minced garlic and sauté for 1 minute, ensuring it remains fragrant but without browning.
03 - Pour in whole milk and heavy cream, stirring until combined. Bring the mixture to a gentle simmer.
04 - Add the drained orzo pasta to the skillet. Simmer for 2 to 3 minutes, allowing the pasta to absorb some sauce.
05 - Stir in freshly grated Parmesan cheese. Continue stirring until the cheese is fully melted and a creamy texture is achieved.
06 - Turn off the heat. Stir in truffle oil, freshly ground black pepper, and salt according to taste.
07 - Serve immediately, garnished with chopped chives or parsley and an additional drizzle of truffle oil as desired.
