Tips & Substitutions

To enhance the flavor, consider adding a splash of white wine to the sauce while cooking. If you don't have scallops, shrimp or crab can be good substitutes. For a gluten-free version, use a gluten-free flour blend. Make sure to pre-bake your pie shell for a crispier base, especially if using Pastry Shells.

Serving Suggestions

Serve Scallops Thermidor with a light salad or steamed vegetables for a balanced meal. It pairs beautifully with Tropical Fruit Medley(Guilt-Free Dessert) for a refreshing end to your meal. A crisp white wine, like a Sauvignon Blanc, complements the rich flavors nicely.

Storage & Reheating

Store leftovers in an airtight container in the refrigerator for up to 2 days. To reheat, place in a preheated oven at 350°F until warmed through, about 15 minutes. Avoid microwaving as it can make the seafood rubbery.

Frequently Asked Questions

What can I use instead of scallops?

If you're unable to find scallops, shrimp or crab meat can be excellent substitutes. They will provide a similar texture and flavor profile, making for a delicious dish. Just adjust the cooking time accordingly, as shrimp cooks faster than scallops.

Can I make this dish ahead of time?

Yes, you can prepare the filling and store it in the refrigerator for up to a day before baking. Just assemble it in the pie shell when you're ready to cook. This allows the flavors to meld nicely, making for a more robust dish.

How do I know when the scallops are done?

Scallops are done when they are opaque and firm to the touch. During baking, look for the Parmesan cheese to turn golden brown as an indicator that the dish is ready. Overcooking can lead to a rubbery texture, so keep an eye on them.
