Step-by-Step Instructions
Step 1: Prep the oven, pan, and pastry
Position a rack in the middle of the oven and preheat to 400°F (204°C).
Set a 2-quart baking dish on a rimmed sheet pan (the filling can bubble, and the sheet pan saves your oven floor). Keep the puff pastry chilled while you make the filling so it bakes up extra flaky.
Step 2: Sauté the vegetables until sweet and tender
In a large skillet or wide saucepan over medium heat, melt 3 tbsp butter. Add the diced onion, celery, and carrots.
Cook, stirring occasionally, for 8–10 minutes, until the onion is translucent and the carrots are starting to soften. Add the minced garlic and cook for 30 seconds, just until fragrant.
Step 3: Build the roux (this is what makes the sauce silky)
Sprinkle 1/3 cup flour over the vegetables and stir well so the flour coats everything. Cook, stirring constantly, for 1 minute. This brief cook removes the raw flour taste and helps the sauce thicken smoothly.
Step 4: Whisk in liquids and simmer until thick
While stirring, slowly pour in 1/2 cup white wine. The mixture will look thick at first; keep stirring and it will smooth out.
Whisk in 1 cup seafood stock and 1/2 cup clam juice. Bring to a gentle simmer and cook for 3–5 minutes, stirring often, until the sauce is noticeably thick and glossy (it should coat a spoon).
Step 5: Finish the lemony herb cream sauce
Reduce heat to low. Stir in 1 cup heavy cream, 1 tbsp Dijon, 1 tsp lemon zest, 2 tbsp lemon juice, 1 tsp kosher salt, 1/2 tsp black pepper, and 1/2 tsp sweet paprika.
Stir in the peas, parsley, dill, and capers (if using). Taste and adjust seasoning. Keep in mind the filling will taste slightly less salty after it’s topped with pastry, so season it so it tastes good now.
Step 6: Add the seafood, assemble, and vent the pastry
Turn off the heat. Fold in the shrimp and fish gently so the fish stays in nice chunks.
Pour the filling into your baking dish and spread into an even layer.
Lay the puff pastry sheet over the dish (trim if needed). Tuck the edges just inside the rim or drape and crimp along the edge of the dish—either is fine; the goal is to seal in steam while still looking rustic.
Cut 4 small slits in the center as vents (about 1 inch long each). This helps steam escape so the pastry stays crisp on top.
Step 7: Egg wash and bake until blistered and golden
Whisk 1 large egg with 1 tbsp water. Brush a thin, even layer over the puff pastry.
Bake at 400°F (204°C) for 25–30 minutes, until the pastry is deep golden with blistered layers and the filling is bubbling at the edges.
If the pastry is browning too quickly before the filling bubbles, loosely tent the top with foil for the last 5–10 minutes.
Let the pot pie rest for 10 minutes before serving. The filling will thicken slightly as it cools, making it easier to scoop.
Pro Tips
- Keep puff pastry cold: The colder it goes into the oven, the higher and flakier it bakes. If it warms up while you assemble, refrigerate the topped dish for 10 minutes before baking.
- Dice carrots small: Small dice (about 1/4 inch) ensures they cook through during the bake and don’t stay crunchy.
- Don’t overcook the seafood: Fold shrimp and fish in off-heat. They’ll finish cooking in the oven, staying tender instead of rubbery.
- Make it brinier (in a good way): The optional capers add a salty, ocean-y pop. If you love that flavor, don’t skip them.
- Prevent a soggy bottom: This recipe is designed as a top-crust pot pie (no bottom crust), which keeps things crisp and easy.
Variations
- Mixed seafood version: Replace the fish with 8 oz scallops and add 4 oz lump crab after the sauce is finished (fold crab in very gently).
- Extra-vegetable version: Add 1 cup corn (fresh or frozen) and 8 oz sliced mushrooms (sauté mushrooms with the onion).
- Gluten-free (filling only): Thicken the sauce with a slurry of 2 tbsp cornstarch mixed with 2 tbsp cold water (add at a simmer). Use a gluten-free pastry top if available.
Storage & Make-Ahead
Refrigerate leftovers: Cool completely, cover, and refrigerate for up to 3 days. Reheat in a 350°F (177°C) oven for 20–25 minutes until hot (the oven re-crisps the pastry better than the microwave).
Make-ahead option (best texture): Make the sauce and vegetables through Step 5, then cool and refrigerate up to 24 hours. When ready to bake, rewarm the sauce until just hot, fold in the raw shrimp and fish, top with puff pastry, and bake as directed.
Freezing: For best puff pastry texture, freeze the filling (without pastry) for up to 2 months. Thaw overnight in the refrigerator, reheat until steaming, then top with fresh puff pastry and bake.
