Eel Pie Recipe: A Classic English Fish Pie

Eel pie is an English savory pie of tender eel in a parsley-scented sauce, baked beneath a crisp pastry lid. This version keeps the filling simple and gently lemony; eel pies have regional and family variations, so it is one practical take rather than a single definitive formula.

Ingredients

14 oz (400 g) chilled puff pastry, thawed if frozen
1½ lb (680 g) boneless, skinless eel fillets, cut into 1-inch (2.5 cm) pieces
3 tbsp (42 g) unsalted butter
1 medium yellow onion, about 5 oz (150 g), finely chopped
1 medium leek, about 5 oz (150 g), white and pale green parts sliced and rinsed well
⅓ cup (40 g) all-purpose flour
2 cups (475 ml) fish stock
½ cup (120 ml) whole milk
1 bay leaf
1 tsp (5 g) Dijon mustard
½ tsp (3 g) fine salt, plus more to taste
¼ tsp (0.5 g) freshly ground black pepper
⅓ cup (15 g) chopped fresh flat-leaf parsley
1 tbsp (15 ml) lemon juice
1 large egg, about 1.8 oz (50 g), beaten with 1 tbsp (15 ml) water, for the pastry wash

Instructions

Prepare the oven and dish. Heat the oven to 400°F (200°C). Set a rack in the middle. Choose a 9-inch (23 cm) deep pie dish or a similar 2-quart (1.9 L) baking dish. Keep the pastry chilled until you are ready to cover the pie. If the fishmonger has not already prepared the eel, ask for skinless, boneless fillets; at home, check each piece carefully for any remaining pin bones and remove them with clean tweezers.
Soften the vegetables. Melt the butter in a wide saucepan over medium heat. Add the onion and leek and cook for about 7 minutes, stirring often, until softened but not browned. Browning can give the sauce a sweeter, darker flavor than intended, so lower the heat if the vegetables begin to color. Sprinkle in the flour and stir for 1 minute to coat the vegetables and cook out the raw flour taste.
Make the parsley sauce. Pour in the fish stock gradually, whisking or stirring as you go so the flour dissolves without forming lumps. Add the milk, bay leaf, mustard, salt, and pepper. Bring the sauce to a gentle simmer, stirring frequently, and cook for about 3 minutes, until it thickens enough to coat the back of a spoon. Keep it at a gentle bubble rather than a hard boil, which can make the sauce catch on the bottom of the pan.
Cook the eel safely. Add the eel pieces and stir gently to coat them in sauce. Simmer for about 5 to 8 minutes, turning the pieces once, until the largest piece reaches 145°F (63°C) when checked with a food thermometer. This is the USDA FSIS safe minimum internal temperature for fish. Eel pieces can vary in thickness, so check more than one piece and continue simmering briefly if needed. Remove the pan from the heat, discard the bay leaf, then fold in the parsley and lemon juice. Taste the sauce and adjust the salt or lemon if necessary.
Cool the filling and add the pastry. Transfer the filling to the baking dish and let it cool for 15 minutes. This brief rest reduces the amount of steam trapped under the pastry and helps keep the bottom of the lid from becoming soggy. Unroll the pastry and lay it over the dish, leaving a small overhang. Trim excess pastry, press the edges against the rim to seal, and cut two or three small slits in the top for steam to escape. Brush the pastry with the beaten egg and water. Avoid letting the egg wash pool around the edge, where it can glue the pastry to the dish.
Bake until crisp. Set the dish on a baking sheet to catch any bubbling sauce. Bake for about 23 minutes, until the pastry is puffed and deep golden and the filling is bubbling through the vents. If the top browns early, loosely cover it with foil for the final few minutes. Rest the pie for 5 minutes before serving so the sauce settles slightly; serve carefully, as the filling will be very hot.

Tips

Buy eel prepared for cooking. Fresh eel can be difficult to find and is awkward to skin and bone at home. Ask a fishmonger for cleaned, boneless fillets and confirm that the weight is for the prepared fish. Check for pin bones even when the fish is sold as boneless. Keep raw fish refrigerated, use separate utensils for it, and wash hands and surfaces after handling.
Use a thermometer, not just the clock. Eel thickness and starting temperature affect how quickly it cooks. Check the center of the largest pieces without touching the pan. Once it reaches 145°F (63°C), stop simmering; the fish will warm again in the oven, and prolonged cooking can make it less tender.
Keep the sauce smooth and the pastry cold. Add stock in stages while stirring, and do not let the sauce boil vigorously. Cold pastry puffs more reliably, so work quickly when topping the dish. If it has become soft while you prepare the filling, chill the covered pie for 10 minutes before baking; add that time to the total.
Substitute thoughtfully. If fresh eel is unavailable, use 1½ lb (680 g) firm, boneless white fish such as cod or pollock and cook it to 145°F (63°C) in the sauce. The result will be leaner and milder, with less of eel’s rich, distinctive flavor. Smoked eel is another option, but it is already cooked and much saltier; fold it into the finished sauce just to warm it, and reduce or omit the added salt.

Serving Suggestions

Serve the pie hot, in generous spoonfuls, with enough sauce in each portion and a little extra chopped parsley on top. Buttered peas, green beans, or simply cooked cabbage make fresh, uncomplicated sides that do not compete with the fish. For a heartier meal, add boiled or mashed potatoes, though the pastry already makes the pie filling. A crisp green salad with a sharp vinaigrette is useful alongside the creamy sauce, especially if the pie is served for lunch.

For a traditional British-style plate, offer a small jug of extra parsley sauce if you have made more than the filling needs. A squeeze of lemon at the table brightens the rich eel without requiring a strongly flavored condiment. Let diners serve themselves from the dish, taking care around the hot filling and flaky pastry.

Variations

Individual pies: Divide the cooled filling among six oven-safe ramekins and cut pastry lids to fit. Seal the edges, make a vent in each lid, and bake until the pastry is golden and the centers are hot. Smaller dishes may bake faster than a single large pie, so begin checking early.

More traditional herbs: Keep parsley as the main herb, or add a small amount of chopped chives. A little chopped tarragon can work, too, but its anise-like flavor is more pronounced and takes the pie in a different direction. Add herbs at the end so their flavor stays fresh.

Richer filling: Replace the milk with an equal amount of cream for a fuller sauce. The filling will be heavier, so a small portion with peas or greens makes a balanced serving. If you prefer a sharper sauce, add another teaspoon of lemon juice rather than increasing the mustard substantially.

Shortcrust instead of puff: A sheet of ready-rolled shortcrust pastry can replace the puff pastry in the same dish. It makes a sturdier, less flaky lid; follow the package directions if they call for a slightly different oven temperature or bake time. Keep the vents, and bake until the pastry is fully cooked and browned, not merely pale and set.

Storage and Reheating

Refrigerate leftover pie within 2 hours of cooking. Cover the dish or transfer portions to a shallow airtight container; cooked fish pie keeps for 3 to 4 days in the refrigerator. For the best pastry texture, store the filling and pastry together rather than leaving slices uncovered, but expect the crust to soften as it sits.

To reheat a portion, place it in an oven-safe dish and warm at 350°F (175°C) until hot throughout. A portion commonly takes about 20 to 30 minutes from the refrigerator, while a larger piece may take longer; cover loosely with foil if the pastry is browning before the middle is hot. Check the center with a food thermometer and reheat leftovers to 165°F (74°C). A microwave is convenient for a single portion, but it softens the pastry; use short intervals and check the center temperature. Freeze well-wrapped portions for up to 2 months for best quality, thaw in the refrigerator, and reheat to 165°F (74°C). Do not leave the pie at room temperature for extended storage.

Frequently Asked Questions

What does eel taste like? Eel has a rich, savory flavor and a tender, substantial texture. It is often compared with other fatty fish, but it has its own character. In this pie, parsley, lemon, and a mild stock-based sauce complement that richness without covering it up.

Can I make eel pie with frozen eel? Yes, provided it is sold for cooking and has been kept frozen safely. Thaw it in the refrigerator, not on the counter, then pat it dry before cutting and cooking. Excess surface water can thin the sauce. Follow the same thermometer check and cook the fish to 145°F (63°C).

Can I prepare the pie ahead? You can make the filling, cool it, and refrigerate it in a covered container for up to 1 day. Put it in the baking dish and add pastry shortly before baking; pastry placed on a cold filling may need a few extra minutes in the oven. Check that the filling is bubbling and, if reheating cooked filling, reaches 165°F (74°C) before serving.

Why is my sauce runny? It may not have simmered long enough to thicken, or the vegetables or fish may have released extra water. Before adding the eel, simmer the sauce for another minute or two while stirring. If the pie is already assembled, let it stand for several minutes after baking; the sauce thickens somewhat as it settles. Avoid adding a large amount of flour directly to hot sauce, which can leave lumps.

Do I have to use puff pastry? No. Shortcrust pastry works as a lid and is easier to handle, though it will be denser and less flaky. You can also serve the filling without pastry over boiled potatoes or with bread, but that changes it from a baked pie into a sauced eel dish. Whatever topping you choose, make sure the fish is cooked to 145°F (63°C).
