Heat olive oil in a large skillet over medium-high heat. Add scallops and sear until golden brown on each side, about 2-3 minutes per side. Remove from the skillet and set aside.
In the same skillet, add butter and melt over medium heat. Stir in lemon zest and white wine, and cook until slightly reduced.
Add Arborio rice to the skillet, stir to coat with butter and toast for about 1 minute. Gradually add chicken broth, one ladle at a time, stirring constantly until liquid is absorbed.
Once rice is cooked and creamy, stir in Parmesan cheese and heavy cream. Season with salt and pepper to taste.
Return scallops to the skillet with risotto and gently fold to combine and warm through.
Notes
Serve immediately with a garnish of fresh parsley, if desired.
