1. Begin by bringing a large pot of salted water to a boil. Gently add the potato gnocchi and cook until they float to the surface, indicating they are done. Drain the gnocchi and set them aside, ready to be incorporated into the creamy sauce.

2. In a large skillet set over medium heat, melt the unsalted butter. Once the butter is melted, add the minced garlic and sauté for 1-2 minutes, until the garlic becomes fragrant and starts to sizzle.

3. Slowly pour in the heavy cream, stirring constantly to prevent any curdling. Bring the mixture to a gentle simmer and let it cook for 3-4 minutes, or until the sauce starts to thicken slightly.

4. Now, it’s time to add the grated Parmesan cheese. Stir the cheese into the cream sauce, allowing it to melt and incorporate seamlessly. Continue to cook, stirring occasionally, until the sauce reaches your desired consistency.

5. Once the sauce is ready, gently add the cooked gnocchi to the skillet, tossing them to coat evenly in the creamy, cheesy goodness. Drizzle the luxurious truffle oil over the top, ensuring each gnocchi is infused with its earthy aroma.

6. Finally, season the Millionaire Gnocchi with salt and freshly ground black pepper to taste. Garnish with the chopped fresh parsley, adding a vibrant pop of color and a burst of herbal flavor.

7. Serve this decadent dish immediately, allowing your guests to savor every bite of this truly indulgent creation.
