How to Make Seafood Shepherd’s Pie with a Potato Crust
- Sear seafood: Heat 1 tbsp olive oil in a large skillet over medium-high heat. Add shrimp, scallops, and fish, cooking 2–3 minutes per side until just opaque.
- Sauté vegetables: Reduce heat to medium, add chopped onion, minced garlic, and diced carrots. Cook 4 minutes, stirring occasionally until softened and fragrant.
- Create creamy filling: Stir in heavy cream, frozen peas, and chopped parsley. Simmer gently for 3 minutes until sauce thickens, coating the seafood and vegetables in a velvety mixture.
For the Potato Crust:
- Boil potatoes: Peel russets and cut into chunks. Boil in salted water for 15 minutes until fork-tender. Drain thoroughly to remove excess moisture.
- Mash and season: Return potatoes to the pot, add butter, egg yolk, salt, and pepper. Mash gently until smooth and creamy, avoiding overmixing for light texture.
- Layer the pie: Transfer the seafood filling into a greased 9-inch baking dish. Spoon mashed potatoes on top, smoothing edges with a spatula to seal and create a decorative crust.
- Bake until golden: Place in a preheated 400°F oven and bake for 20–25 minutes, until the crust is crisp and golden brown and the filling bubbles at the edges.
- Rest before serving: Remove from oven and let stand 5 minutes. This rest helps set the layers and makes slicing easier for perfect portions.
Optional: garnish with fresh chives for a pop of color and fresh flavor.

Expert Tips for Seafood Shepherd’s Pie with a Potato Crust
- Choose fresh seafood: Using fresh shrimp, scallops, and fish enhances flavor and texture, making your seafood shepherd’s pie with a potato crust truly standout.
- Dry potatoes well: After boiling, drain and steam potatoes briefly to remove moisture—this ensures a crispy, golden crust rather than a soggy topping.
- Don’t overmix mash: Gently mash your potatoes to keep them light and fluffy; overworking can make the crust dense and heavy.
- Seal edges tightly: Smooth the potato crust down the sides of the dish to lock in the creamy seafood filling and prevent bubbling over while baking.
- Rest before slicing: Letting the pie rest after baking helps the layers firm up, making serving neater and preserving the crispy crust.
- Customize veggies thoughtfully: Swap or add vegetables like corn or green beans, but keep balance so the rich seafood filling remains the star.

Seafood Shepherd’s Pie with a Potato Crust Recipe FAQs
How do I know if my seafood is fresh enough for this shepherd’s pie?
Look for shrimp and scallops that smell clean and briny, not fishy or sour. Fresh white fish fillets should be firm with moist, translucent flesh and no discoloration or dark spots. Freshness really shines through in this recipe, so shop at trusted fishmongers or well-stocked seafood counters.
Can I store leftover Seafood Shepherd’s Pie with a Potato Crust in the fridge?
Absolutely! Place any leftovers in an airtight container once the pie has cooled completely. Stored properly in the fridge, it will stay fresh for about 3 to 4 days. When reheating, warming in the oven helps keep the potato crust crisp, which I recommend over the microwave for the best experience.
Is it possible to freeze the seafood shepherd’s pie, and if so, how should I do it?
Very much so! Cool the pie thoroughly at room temperature—never leave out more than 2 hours. Then, divide into individual or family-sized portions, sealing each tightly in freezer-safe containers or heavy-duty wrap. Label with the date and freeze for up to 2 months. To enjoy later, thaw overnight in the fridge, then reheat in a preheated 350°F oven for about 20 minutes to revive the crispy crust and ensure even warming.
What if my potato crust turns out soggy instead of crispy?
This is a common hiccup, but easily fixed! Make sure to drain boiled potatoes very well, even steaming them briefly in the pot after draining to evaporate extra moisture. Avoid overmixing the mash, which can make it gummy—gentle folding is best. Also, sealing the potato crust tightly along the baking dish edges traps the filling and prevents moisture from leaking out and soaking the crust. Baking at a high temperature (400°F) helps achieve that golden crisp.
Can pets eat the leftovers from this Seafood Shepherd’s Pie with a Potato Crust?
While the ingredients are wholesome for humans, seafood and seasonings like garlic and onion used in this dish can be harmful to pets, especially dogs and cats. It’s best to keep this flavorful comfort food just for your family’s table and provide your furry friends with their own safe treats.
