01 - Warm the broth in a small saucepan over low heat; keep it simmering gently throughout the risotto cooking process.
02 - In a large saucepan, heat 1 tablespoon olive oil and 2 tablespoons butter over medium heat. Add the finely chopped shallot and sauté until translucent, about 2 minutes.
03 - Stir in the Arborio rice and cook, stirring constantly, until the edges become translucent, about 2 minutes.
04 - Pour in the white wine and stir until mostly absorbed by the rice.
05 - Add the warm broth one ladleful at a time, stirring frequently. Wait until each addition is almost fully absorbed before adding more. Continue this process until the rice is creamy and al dente, 18–22 minutes total.
06 - Stir in Parmesan cheese, lemon juice, lemon zest, salt, and pepper. Remove from heat and cover to keep warm while preparing scallops.
07 - Season the scallops generously with salt and freshly ground black pepper on both sides.
08 - Heat 1 tablespoon olive oil and 1 tablespoon butter in a large skillet over high heat. When the pan is very hot, add scallops without overcrowding. Sear without moving for 1.5–2 minutes until a golden crust forms. Flip and cook another 1–2 minutes until just opaque in the center.
09 - Spoon risotto onto plates and top with 4 scallops per serving. Garnish with chopped chives or parsley and lemon wedges.
