01 - In a large saucepan, heat 2 tablespoons butter and 1 tablespoon olive oil over medium heat. Add the shallot and cook until softened, about 2 minutes. Add the Arborio rice and stir for 1-2 minutes until the grains are translucent around the edges.
02 - Pour in the white wine and stir until completely absorbed. Add the warm broth, one ladleful at a time, stirring frequently and allowing each addition to be absorbed before adding more.
03 - Continue adding broth for 18-20 minutes until the rice is creamy and al dente. Stir in Parmesan cheese, season with salt and pepper, and keep warm.
04 - Season scallops generously with salt and pepper. In a large skillet, heat olive oil over medium-high heat. Add scallops in a single layer without crowding the pan. Sear for 2 minutes per side until golden brown and just cooked through, then remove to a plate.
05 - Reduce heat to medium, add butter, minced garlic, lemon zest, and lemon juice to the skillet. Stir for 30 seconds, scraping up any browned bits from the bottom of the pan.
06 - Return scallops to the pan, spoon the lemon garlic butter sauce over them, and cook for 30 seconds to heat through. Spoon risotto onto plates, top with scallops, drizzle with remaining lemon garlic sauce, and garnish with chopped parsley.
