Ingredient Breakdown
- Sea Scallops
- Olive Oil
- Mushrooms
- Heavy Cream
- White Wine
- Dijon Mustard
- Grated Cheese
- Salt and Pepper
- Fresh Parsley
Let’s Get Cooking!
Preheat your broiler. Getting it nice and hot will ensure a perfect bubbling cheese topping.
In a large skillet, heat olive oil over medium-high heat. Meanwhile, season the scallops with a couple pinches of salt and pepper.
Sear the scallops for 2-3 minutes on each side until golden brown. You’ll know they’re ready when they have that perfect caramelization. Remove and set aside for later.
In the same pan, add sliced mushrooms and cook until they’re tender and slightly caramelized, about 3-4 minutes. You want them to be fragrant and a little golden.
Add white wine and bring to a simmer. After about a minute, reduce heat and stir in heavy cream and Dijon mustard. Cook until the sauce thickens slightly, about 3-4 minutes. It’s going to smell incredible!
Return scallops to the skillet, coating them in the sauce. Make sure every piece is covered with all that yummy goodness.
Transfer the mixture to a cassolette or oven-safe dish, and feel free to spread it out evenly. This is the part where it starts looking fancy!
Sprinkle grated cheese on top. Go generous here; after all, we’re going for cheesy elegance!
Broil until the cheese is golden and bubbly, which should take about 3-5 minutes. Watch it closely so it doesn’t burn, because we want golden, not charcoal!
Garnish with fresh parsley and serve immediately. Get ready; the family is going to swoon over this one!

Storage
Leftovers can be kept in the refrigerator for 3-4 days in an airtight container. Just make sure to cool it down to room temperature before sealing it up, no one wants soggy cassolette!
Reheating Instructions
When it’s time to dig in again, the best method is to reheat it in the oven. Just pop it in at 350°F (175°C) until warmed through (about 15-20 minutes). This way, you’ll keep that lovely cheesy crust. Alternatively, you can microwave it in short bursts; just be careful not to overdo it!
