01 - Heat olive oil and 2 tablespoons butter in a large saucepan over medium heat. Add shallot and cook until softened, about 2 minutes.
02 - Stir in Arborio rice and cook, stirring, for 1-2 minutes until lightly toasted.
03 - Pour in white wine and stir until fully absorbed by the rice.
04 - Add warm broth in 1/2 cup increments, stirring gently and allowing each addition to absorb before adding the next, continuing until rice is creamy and al dente, approximately 18-22 minutes.
05 - Incorporate grated Parmesan and optional heavy cream. Season with salt and black pepper, then cover and set aside.
06 - Pat scallops dry and season both sides with salt and black pepper.
07 - Heat olive oil in a large nonstick skillet over medium-high heat until shimmering. Place scallops in a single layer and sear without moving for 2 minutes until golden on the underside.
08 - Turn scallops over, add butter and minced garlic, and cook for 1-2 minutes until scallops are just opaque.
09 - Remove skillet from heat, add lemon zest, lemon juice, and parsley, swirling to coat scallops evenly.
10 - Divide risotto among plates, top with seared scallops, and drizzle with lemon-garlic butter from the pan. Garnish with additional parsley and lemon zest if desired.
