Ingredients
(Serves 6)

• 2 tablespoons butter
• 1 small onion, finely chopped
• 2 celery stalks, diced
• 2 medium carrots, diced
• 2 cloves garlic, minced
• 1/3 cup all-purpose flour
• 2 cups seafood or chicken stock (low-sodium preferred)
• 1 cup half-and-half or whole milk
• 1/2 cup heavy cream
• 1 teaspoon Dijon mustard
• 1/2 teaspoon Old Bay seasoning (or a pinch of paprika + celery salt)
• 1/2 teaspoon salt, plus more to taste
• 1/4 teaspoon black pepper
• 1 pound mixed seafood (shrimp, scallops, flaked white fish, and/or crab meat) — shrimp and lump crab work beautifully
• 1 cup frozen peas (no need to thaw)
• 2 tablespoons fresh parsley, chopped
• 1 sheet puff pastry, thawed (or use a pre-rolled pie crust)
• 1 egg beaten with 1 tablespoon water (egg wash)
• Lemon wedges, for serving (optional)

Simple substitutions and pantry tips

• No puff pastry? Use refrigerated pie crust or make a biscuit topping. Puff pastry gives that flaky, restaurant-style finish.
• No half-and-half? Use milk plus a splash of cream or just whole milk — the sauce will still be delicious.
• Don’t have Old Bay? Use a mix of paprika, garlic powder, and a dash of cayenne for warmth.

Step-by-step Directions

1. Preheat and prep:

   • Preheat your oven to 400°F (200°C). Lightly butter or spray a 9-inch pie dish or a 2-quart baking dish. Keep the puff pastry chilled until ready to top.

2. Sauté the aromatics:

   • In a large skillet over medium heat, melt the butter. Add the chopped onion, carrots, and celery. Cook, stirring occasionally, until vegetables are soft — about 6–8 minutes. Add garlic and cook for another 30 seconds until fragrant.

3. Make the roux and sauce:

   • Sprinkle the flour over the vegetables and stir constantly for 1–2 minutes. This cooks off the raw flour taste. Slowly whisk in the stock until lumps are gone and the mixture thickens. Add the half-and-half and cream, whisking to combine. Bring the mixture to a low simmer.

4. Season and finish the filling:

   • Stir in the Dijon mustard, Old Bay (or substitute), salt, and pepper. Let the sauce simmer for 2–3 minutes until it’s glossy and coats the back of a spoon. Taste and adjust seasoning.

5. Add seafood and peas:

   • Fold in the mixed seafood and frozen peas. Cook gently for 3–4 minutes — you just want to heat the seafood through. If you’re using pre-cooked shrimp or crab, add them at the end to warm through and avoid becoming rubbery. Stir in the parsley.

6. Assemble the pot pie:

   • Transfer the seafood mixture to the prepared baking dish. Top with the puff pastry sheet, tucking the edges down around the dish. Brush the pastry with egg wash and cut a few small slits for steam to escape.

7. Bake:

   • Bake for 20–25 minutes, or until the pastry is puffed and golden brown and the filling is bubbling around the edges. If the pastry browns too quickly, loosely tent with foil.

8. Rest and serve:

   • Let the pot pie rest for 5–10 minutes before serving. Squeeze a little lemon over each portion if you like a bright finish.

Quick timeline for busy nights

• Prep veggies and puff pastry while the filling simmers. Use thawed frozen shrimp and pre-shredded carrots to shave off 10–15 minutes. You can also assemble ahead and refrigerate for up to 24 hours, then bake when ready.

Cooking Tips (because small things make big differences)

• Don’t overcook the seafood: If using raw shrimp or scallops, cook just until they’re opaque. If using pre-cooked crab or shrimp, add them at the end to heat through.
• Sauce too thin? Simmer a little longer. Sauce too thick? Stir in a splash of stock or milk.
• Puff pastry puffing too aggressively? Rotate the dish halfway and cover with foil if the crust gets too dark.
• Want deeper flavor? Sauté a pinch of tomato paste with the vegetables for a caramelized depth (trust me — it’s a tiny cheat that pays off).

Personal Anecdote
This dish became my go-to the summer my sister Patricia and I hosted a small neighborhood potluck. Between chasing toddlers and answering a million “What time?” texts, we needed something that looked like effort but didn’t require babysitting the stove. The pot pie disappeared fastest, hands-down. The best compliment? My neighbor asked for the recipe and later confessed she’d told her picky teen there were “mystery vegetables” inside — and he cleaned his plate. Mission accomplished.

Tips for feeding picky eaters

• Keep veggies finely diced so they blend into the creamy sauce.
• Offer a little grated cheese on the side for kids who love that extra layer.
• Let hungry teens top their own portions with breadcrumbs or extra parsley to feel involved.

Make-ahead and storage

• Assemble the pot pie and cover tightly with plastic wrap — refrigerate up to 24 hours before baking. This is a lifesaver for busy evenings.
• Leftovers store in the fridge for up to 3 days. Reheat in a 350°F oven for about 15–20 minutes to refresh the crust, or microwave individual portions for a quick lunch.
• To freeze: Bake, cool, and wrap tightly, or assemble and freeze unbaked. Thaw overnight in the fridge before baking.

Frequently Asked Questions (FAQs)

Q: Can I use a different seafood mix?
A: Absolutely. Use what you love: shrimp, scallops, white fish, lobster, or crab. If using stronger-flavored seafood like salmon, adjust seasonings to taste.

Q: Can I make this dairy-free?
A: Yes. Substitute butter with vegan margarine and use coconut milk or an unsweetened oat cream alternative for the sauce. The flavor will be slightly different but still comforting.

Q: Can I substitute the puff pastry with a biscuit topping?
A: Yes. A biscuit or drop-biscuit topping works great — bake a little longer until biscuits are golden and the filling is bubbling.

Q: How do I keep the filling from becoming too watery?
A: Make sure to cook the roux (flour and butter) for a minute before adding liquid so it thickens properly. Also, drain any watery seafood (thawed frozen shrimp can release liquid) and add peas only at the end.

Q: Is this recipe freezer-friendly?
A: Yes. You can freeze a fully baked pot pie (wrap tightly) or assemble and freeze unbaked. Thaw overnight before baking for best results.

Serving suggestions

• Keep it simple: a crisp green salad and crusty bread.
• Make it a full dinner: roasted asparagus or garlic green beans pair beautifully.
• For a cozy weekend, open a bottle of white wine (Chardonnay or Sauvignon Blanc) and savor the extra time at the table.

A few flavor-boosting ideas

• Add a splash of white wine to the sauce before adding cream for brightness.
• Finish with fresh lemon zest and parsley to cut through the richness.
• Stir in a tablespoon of cream cheese for extra silkiness when you want an indulgent sauce.
