Step-by-Step Instructions
Step 1: Prepare the Scallops
Pat the scallops completely dry using paper towels. Removing excess moisture ensures they sear beautifully instead of steaming.
Season both sides lightly with salt and freshly ground black pepper.
Allow them to rest at room temperature for 10 minutes before cooking.
Time: 10 minutes
Step 2: Sear the Scallops
Heat olive oil and butter in a large skillet over medium-high heat.
Once hot, place the scallops into the pan without overcrowding.
Cook for approximately 1½ to 2 minutes on each side until they develop a golden crust.
The center should remain slightly translucent because the scallops will continue cooking in the oven.
Transfer to a plate and drizzle with lemon juice.
Time: 5 minutes
Heat Intensity: Medium-High
Step 3: Cook the Mushrooms
Reduce the heat to medium.
Add butter to the same skillet.
Add sliced mushrooms and shallots.
Cook for about 6 minutes until mushrooms become golden and most of their moisture evaporates.
Add minced garlic and cook for another minute until fragrant.
Time: 7 minutes
Heat Intensity: Medium
Step 4: Make the White Wine Sauce
Pour the white wine into the skillet.
Scrape the browned bits from the bottom of the pan.
Allow the wine to reduce by half.
Add seafood stock and simmer for another 3 minutes.
Stir in heavy cream, Dijon mustard, thyme, parsley, salt, and pepper.
Cook gently until the sauce thickens enough to coat the back of a spoon.
Time: 10 minutes
Heat Intensity: Medium-Low
Step 5: Combine Everything
Return the scallops to the creamy sauce.
Gently coat each scallop with the sauce.
Avoid overcooking.
Cook only 1 additional minute.
Step 6: Prepare the Topping
In a small bowl, combine:
- Gruyère cheese
- Parmesan cheese
- Breadcrumbs
- Melted butter
Mix until evenly coated.
Step 7: Assemble
Preheat oven to 425°F (220°C).
Divide the scallop mixture evenly among four scallop shells or a baking dish.
Sprinkle the cheese and breadcrumb mixture evenly over each serving.
Step 8: Bake
Bake for 10–12 minutes until bubbling.
Switch to broil for the final 2–3 minutes to achieve a golden, crispy topping.
Watch carefully to prevent burning.
Time: 12–15 minutes
Heat Intensity: High (Oven)
Chef’s Tips
- Use dry-packed sea scallops for the best caramelization.
- Avoid overcooking, as scallops become rubbery quickly.
- Freshly grated Gruyère melts more smoothly than pre-shredded cheese.
- Dry white wines such as Sauvignon Blanc or Chardonnay work best.
- Patting the scallops dry is essential for a beautiful golden crust.
- Prepare the sauce ahead of time and bake just before serving for stress-free entertaining.
