Ingredients on a kitchen counter: glass bowl with scallops, asparagus, olive oil bottle, red onion, lemons, basil, spices, and a knife.

Sea Scallops

Sea scallops are prized for their delicate sweetness and tender, buttery texture. When properly seared, they develop a beautiful golden crust on the outside while staying soft and juicy inside. They’re a staple in fine dining but surprisingly approachable for home cooks when handled correctly.

Scallops are also a lean source of protein and cook quickly, making them perfect for weeknight meals that still feel elevated. The key is patting them completely dry and giving them space in the pan—this ensures that signature sear instead of steaming.

Basil & Lemon

Fresh basil and lemon are a classic pairing that instantly brightens any dish. Basil brings a sweet, slightly peppery herbal note, while lemon adds acidity and freshness that balances the richness of the scallops and olive oil.

Using both lemon zest and juice allows you to layer flavor throughout the dish. The zest infuses the oil with citrus aroma, while the juice finishes the scallops with a clean, vibrant pop that ties everything together beautifully.

Recipe Origin & Inspiration

This recipe was inspired by our love of light, Mediterranean-style seafood dishes that highlight fresh ingredients without overcomplicating the process. We wanted something that felt sophisticated yet approachable—something you could serve for a special occasion or simply because you’re craving a fresh, flavorful dinner.

Tips, Serving Suggestions & Storage

Make sure scallops are completely dry before cooking to achieve a proper sear.
Use a heavy skillet, such as cast iron or stainless steel, for best browning.
Do not overcrowd the pan when cooking scallops—work in batches if needed.
Medium heat works best to avoid burning the oil while still creating a crust.
Trim asparagus ends to remove any woody texture.
Slice red onions thinly so they soften quickly and evenly.
Add lemon juice at the end to keep the scallops tender and bright.
Serve immediately for the best texture and flavor.
Pair with crusty bread, orzo, or rice to soak up the lemon-basil oil.
Store leftovers in an airtight container in the refrigerator for up to 2 days.

Ingredients

12 ounces sea scallops, thawed if frozen
2 lemons
3 tablespoons olive oil, divided
1 pound asparagus spears, trimmed and cut into 2-inch pieces
1 medium red onion, sliced
Salt, to taste
Black pepper, to taste
2 to 3 fresh basil sprigs, including stems
1 tablespoon butter (optional)
2 tablespoons fresh basil leaves, cut into chiffonade

Instructions

Rinse the scallops and pat them completely dry with paper towels. Set aside.
Using a citrus zester, remove the zest from one lemon and set aside. Juice the lemon and reserve the juice.
Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the asparagus and red onion and cook for 2 to 3 minutes until just tender. Season with salt and black pepper. Transfer to a serving platter and keep warm.
In the same skillet, add the remaining 2 tablespoons of olive oil along with the lemon zest and basil sprigs. Cook for about 1 minute until fragrant.
Remove and discard the lemon zest and basil sprigs, leaving the infused oil in the skillet.
Add the scallops to the hot oil and cook for 3 to 5 minutes, turning once, until opaque and lightly browned.
Remove from heat and stir in the reserved lemon juice and butter, if using. Season with additional salt and black pepper to taste.
Spoon the scallops over the asparagus and onion mixture. Cut the remaining lemon into wedges and garnish with lemon wedges and fresh basil before serving.
