Seafood Pot with Cheddar Bay Biscuits

The first time I made this seafood pot pie, it was actually on a dare from my brother-in-law who claimed I couldn't improve upon a classic. I'd been experimenting with Cheddar Bay biscuit dough in my head for weeks, wondering what would happen if I turned that garlicky, cheesy goodness into a pot pie topping. The moment I pulled it from the oven, with that golden-brown biscuit crust rising over the creamy seafood filling, I knew I'd stumbled onto something special. Now it's the one dish my family requests for birthday dinners.

Last winter, during that terrible snowstorm that kept us housebound for three days, I made this pot pie with frozen shrimp and crab I'd squirreled away in the freezer. My neighbor came over with a bottle of white wine, and we stood around the oven watching the biscuits rise through the glass door. Something about this dish brings people to the kitchen, maybe it's the buttery smell or just the promise of something warming and rich on a cold night.

Ingredients

• Large shrimp: I've learned that chopping them into bite-sized pieces distributes the sweet seafood flavor throughout every spoonful, and they stay tender when you don't overcook them
• Lump crab meat: Splurge on the good stuff here because those large, juicy chunks are what make each bite feel luxurious, and pick through it carefully for any shell fragments
• Firm white fish: Cod or haddock holds its shape beautifully in the creamy sauce without flaking apart into mush
• Frozen peas: They add little bursts of sweetness and pop of color against the pale sauce, and they're already perfectly blanched
• Unsalted butter: You'll use this for both the velouté sauce and the biscuit topping, so keep it cold for the biscuits but let it melt gently for the sauce base
• All-purpose flour: This creates the roux that thickens your sauce into something spoon-coating and luxurious
• Seafood stock: If you can't find it at the store, homemade shrimp shell stock adds incredible depth, but fish broth works beautifully too
• Whole milk: The fat content here creates a silky, rich sauce that won't separate or turn grainy
• Old Bay seasoning: This is the secret weapon that ties everything together with that classic coastal flavor profile
• Sharp cheddar cheese: The sharp variety cuts through the richness of the cream sauce and adds that distinctive Cheddar Bay flavor we all love
• Cold buttermilk: The acidity in buttermilk activates the baking soda for extra tall, fluffy biscuits, and keeping it cold creates those flaky layers

Instructions

Get your oven ready and heat things up:

Preheat that oven to 400°F and give your baking dish a quick swipe of butter or oil, which will save you from sticky cleanup later

Build your flavor foundation:

Melt your butter in a large skillet and let those onions, carrots, and celery soften until they're fragrant and starting to turn translucent, about five minutes of gentle cooking

Create your creamy base:

Sprinkle the flour over the vegetables and stir constantly for two minutes to cook out that raw flour taste, then slowly whisk in your liquids until everything's smooth and let it bubble until it thickens nicely

Add the seafood and season it right:

Stir in your Old Bay, salt, pepper, and fresh parsley, then gently fold in the shrimp, crab, fish, and peas, cooking just long enough to coat everything in that velvety sauce

Transfer and prep for the topping:

Pour that gorgeous seafood mixture into your prepared baking dish and set it aside while you make the biscuits

Mix the dry biscuit ingredients:

Whisk together your flour, baking powder, baking soda, garlic powder, sugar, and salt in a large bowl until everything's evenly distributed

Work in that cold butter:

Cut the cold butter into the flour mixture using a pastry cutter or your fingers until it looks like coarse crumbs with some pea-sized pieces remaining, which creates those flaky layers we want

Add cheese and bring the dough together:

Fold in that sharp cheddar and fresh herbs, then stir in the cold buttermilk just until the dough comes together, being careful not to overwork it

Top the pie and bake:

Drop large spoonfuls of biscuit dough evenly over the seafood filling and bake for 25 to 30 minutes until the biscuits are golden brown and cooked through

Finish with garlic butter glory:

While the pie bakes, mix your melted butter with garlic powder and parsley, then brush it generously over those hot biscuits the moment they come out of the oven

Let it rest and serve:

Give the pot pie about 10 minutes to cool slightly so the sauce has time to set up a bit, making serving easier and neater

My daughter asked for this pot pie at her graduation dinner instead of the usual steak or prime rib. We served it with that crisp Sauvignon Blanc the recipe suggests, and even relatives who swore they didn't like seafood went back for seconds. Something about the familiar comfort of pot pie paired with the briny sweetness of shrimp and crab just makes people feel at home.

Making It Ahead

You can assemble the entire filling and biscuit dough separately up to a day in advance, storing them in the refrigerator. Just let the biscuit dough come to room temperature for about 20 minutes before topping and baking, otherwise the cold dough won't cook through before the filling bubbles over.

Seafood Substitutions

While the combination of shrimp, crab, and white fish is classic, don't be afraid to swap in scallops or even small chunks of lobster for a more luxurious version. The key is keeping the total seafood weight consistent and cutting everything into similar-sized pieces so everything cooks evenly.

Serving Suggestions

This pot pie is substantial enough to stand alone as a complete meal, but a simple green salad with a bright vinaigrette cuts through the richness beautifully. I also love serving roasted asparagus or broccolini alongside when feeding a crowd.

• A crisp white wine like Sauvignon Blanc or Pinot Grigio balances the creamy sauce
• Lemon wedges on the table let guests add brightness to their own servings
• Extra Old Bay on the side for those who love that extra kick

There's something deeply satisfying about taking that first spoonful, breaking through the cheesy biscuit crust into that creamy, seafood-filled center. This is the kind of food that makes even a Tuesday evening feel like a special occasion.

Recipe FAQs

→ Can I use frozen seafood for this dish?

Yes, frozen shrimp and crab work well. Thaw completely before using and pat dry to prevent excess liquid in the filling. Frozen fish should also be thawed and patted dry before adding.

→ What other seafood can I include?

Lobster, scallops, or even salmon make excellent additions or substitutions. Adjust cooking times slightly—scallops and lobster cook faster than firm white fish.

→ Can I make this ahead of time?

Prepare the seafood filling up to a day in advance and refrigerate. The biscuit dough is best made fresh, but you can mix dry ingredients ahead. Assemble and bake just before serving.

→ How do I store leftovers?

Store in an airtight container in the refrigerator for up to 3 days. Recover in the oven at 350°F to maintain biscuit texture. The biscuits will soften slightly but still taste delicious.

→ Can I make individual portions?

Absolutely. Use ramekins or individual baking dishes and reduce baking time to 18-22 minutes. Great for dinner parties and presents beautifully at the table.

→ What wine pairs well with this dish?

A crisp white wine like Sauvignon Blanc, Pinot Grigio, or Chardonnay complements the rich seafood and cheddar flavors beautifully. The white wine in the filling also enhances the sauce depth.
