Begin by pouring the vegetable broth into a medium saucepan and bringing it to a vigorous boil over high heat. Carefully add the orzo pasta once the broth is boiling, stirring occasionally to prevent the pasta from sticking. Cook for about 8-10 minutes, or until the orzo is al dente.
While the orzo is cooking, prepare the sauce. In a large skillet, heat the olive oil over medium heat. Once hot, add the diced onion and sauté for 3-4 minutes, or until the onion turns translucent and soft.
Add the minced garlic to the skillet with the onions. Sauté for an additional 1-2 minutes, stirring frequently, until the garlic becomes fragrant but takes care not to let it brown.
Lower the heat to a gentle simmer and pour in the heavy cream, stirring continuously to combine the flavors without bringing it to a boil.
Once the orzo has finished cooking, drain it and add it directly into the skillet. Stir well to merge the pasta with the creamy garlic sauce.
Incorporate the lemon zest and freshly squeezed lemon juice into the mixture, followed by the grated Parmesan cheese. Stir thoroughly until the cheese is melted.
Taste the dish and season with salt and freshly cracked black pepper as needed. If the mixture is too thick, add a splash of the reserved broth.
Remove from the heat and allow the orzo to sit for a minute to let the flavors meld before serving.
