Make the Risotto
Sauté aromatics: Heat butter in a large non-stick skillet over medium heat. Add shallots and garlic; cook 1–2 minutes until fragrant.
Add mushrooms: Stir in mushrooms and cook 2 more minutes until softened.
Toast the rice: Add the arborio rice, stirring constantly for 1 minute to coat in butter.
Deglaze with wine: Pour in the white wine and cook 1 minute until mostly absorbed.
Add broth gradually: Add hot chicken broth ½ cup at a time, stirring often and allowing most of the liquid to absorb before each addition. Continue until the rice is creamy and al dente (about 20 minutes).
Finish with flavor: Stir in Parmesan cheese, parsley, salt, and pepper. Cover and keep warm while preparing the scallops.
Sear the Scallops
Prepare scallops: Pat scallops dry and season both sides with salt and pepper.
Sear: Heat oil in a cast iron or stainless steel skillet over high heat. Once hot and slightly smoking, add scallops and cook 2 minutes per side, undisturbed, until golden brown. Remove and set aside.
Make the Lemon Butter Sauce
Deglaze the pan: Remove the skillet from heat for 1–2 minutes. Add butter, lemon juice, and parsley, stirring until melted and fragrant.
Combine: Return scallops to the pan for 30–90 seconds, spooning butter over the top to glaze.
Assemble
Divide the risotto among serving bowls, top with seared scallops, and drizzle with the lemon butter sauce. Garnish with extra parsley and lemon wedges. Serve immediately.
