01 - Warm the broth in a small saucepan over low heat; maintain a gentle simmer throughout the cooking process.
02 - In a large saucepan, heat 1 tablespoon olive oil and 2 tablespoons butter over medium heat. Add the chopped shallot and sauté until translucent, approximately 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 continuously until mostly absorbed by the rice.
05 - Add warm broth one ladleful at a time, stirring frequently. Allow each addition to be almost fully absorbed before adding the next. 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 maintain warmth while preparing scallops.
07 - Season scallops generously with salt and pepper. Heat 1 tablespoon olive oil and 1 tablespoon butter in a large skillet over high heat until the pan is very hot.
08 - Add scallops without overcrowding the pan. Sear without moving for 1.5–2 minutes until a golden-brown crust forms. Flip and cook an additional 1–2 minutes until just opaque in the center.
09 - Spoon risonto onto warmed plates. Arrange 4 scallops per serving atop the risotto. Garnish with chopped chives or parsley and fresh lemon wedges.
