Preheat oven to 400°; place 2 large pieces of foil on a sheet pan + oil the foil; pat scallops dry, season with salt/pep + divide to foil; top each with ½ of butter round + fresh thyme; fold empty side of foil over ingredients; working from one end, tightly fold edges of foil creating a sealed half-moon shape; repeat with other foil

Bake foil packs 9-11 min until fish is firm, opaque + cooked through

Microwave 2 sweet potatoes in their wrappers on high, 6-8 min, flipping halfway through (caution, that's a hot potato!); carefully cut in half

Discard thyme stems; divide scallops to plates alongside sweet potatoes (Don't forget all the yummy butter sauce in each foil!)
