Seared Scallops with Brown Butter, Butternut Squash and Parmesan

Few weeknight dinners look this elegant and come together this fast. Large sea scallops develop a deep golden crust in a hot cast iron skillet, while cubed butternut squash and whole sage leaves cook in the same pan. Melting butter foams and browns into a nutty sauce that coats everything, and a generous shower of freshly grated parmesan finishes the plate.

This is a simple, confident dinner built around one skillet and a handful of pantry-friendly ingredients. Sweet, tender butternut squash cubes and fragrant sage give the scallops a cozy autumn character, while browned butter adds the nutty flavor that ties everything together.

The method is straightforward: dry and season the scallops, sear them until golden, then brown the butter with the squash and sage and spoon it over the seafood. Freshly grated parmesan adds salty depth at the end.

Plan on about half an hour from start to finish, and have the squash diced and the cheese grated before the skillet goes on the heat so the cooking moves smoothly.

Ingredients

Why this recipe works

The scallops sear well because they are patted dry and placed in a hot skillet with a thin film of oil. Moisture on the surface steams the scallop instead of browning it, so drying them first and leaving them undisturbed for the first minutes produces the deep golden crust that gives the dish its contrast.

Turning them only once keeps the interior tender and sweet, with centers that turn opaque rather than rubbery.

Butter browns because its milk solids toast as the water cooks off. Once the butter foams and turns golden, it develops toasty, nutty flavors that taste far more complex than melted butter. Adding the squash and sage to the same butter lets the squash soften and the sage crisp in that flavored fat, so every component on the plate shares one warm, savory sauce.

Notes and substitutions

Choose large sea scallops, sometimes sold as U10 or U20 by count per pound, because they are thick enough to sear on the outside while staying tender inside. Diver scallops, which are dry packed and free of added water, brown more deeply than wet-packed scallops. Check the label or ask the fishmonger, and avoid any scallops that look wet or cloudy in the package.

A 12-inch cast iron skillet holds heat evenly and gives the best crust on the scallops. A heavy stainless steel pan also works. A sharp chef's knife and a wooden board make dicing the squash easier and safer.

A box grater produces the fine parmesan that melts lightly over the hot food. Tongs let you turn each scallop without piercing it, which keeps the juices inside.

• Large sea scallops: Large dry-packed diver scallops, which sear to a deeper golden crust
• Butternut squash: Acorn squash or sweet potato, cut into similar small cubes
• Parmesan cheese: Aged Pecorino Romano, which is saltier and sharper
