01 - Heat 2 tablespoons olive oil and 2 tablespoons butter in a large saucepan over medium heat. Add the finely chopped onion and sauté until softened, approximately 3 minutes. Add the minced garlic and cook for 1 minute until fragrant.
02 - Stir in the arborio rice and cook for 1 to 2 minutes, stirring constantly, until the rice grains become lightly translucent around the edges.
03 - Pour in the 1/2 cup dry white wine and stir continuously until fully absorbed by the rice.
04 - Add the warm broth one ladle at a time, stirring frequently. Allow each addition to be completely absorbed before adding the next. Continue this process for approximately 18 to 20 minutes until the rice is creamy and tender yet still slightly firm to the bite (al dente).
05 - Stir in the grated Parmesan cheese, heavy cream, salt, and pepper until well combined. Remove from heat, cover, and keep warm while preparing the scallops.
06 - Pat the scallops completely dry with paper towels. Season both sides generously with salt and freshly ground black pepper.
07 - Heat 1 tablespoon olive oil and 1 tablespoon butter in a large skillet over high heat. When the pan is hot and the butter is foaming, add the scallops in a single layer without overcrowding. Sear for exactly 2 minutes per side until golden brown crust forms and the scallops are just cooked through.
08 - Reduce the heat to low. Add the minced garlic to the pan and cook for 30 seconds until fragrant, being careful not to burn.
09 - Add the lemon zest and lemon juice to the pan, swirling gently to coat the scallops evenly. Remove from heat immediately.
10 - Spoon the creamy risonto onto warmed plates, arranging it as a bed. Top with the seared scallops and garnish generously with chopped fresh parsley. Serve immediately while hot.
