Cheddar Bay Biscuit Seafood Pie takes the biscuit everyone fights over at the seafood restaurant and turns it into dinner. A creamy shrimp and crab filling bakes under drop biscuits loaded with sharp cheddar, then gets brushed with garlic butter the second it comes out of the oven.
It's the kind of meal that looks like it took all day but comes together in about an hour, mostly hands-off while the oven does the work. One skillet holds the filling and the topping, so cleanup stays simple too.
This version leans on a quick roux instead of canned soup, so the sauce actually tastes like butter and seafood instead of salt. The biscuits go on cold and come out craggy and golden, with pools of garlic butter soaking into every crack.
What Goes Into This Seafood Pie
This pie leans on real seafood, not a can of soup, so buy shrimp and crab that smell clean and briny rather than fishy. A block of sharp cheddar you grate yourself melts smoother into the biscuit dough than the pre-shredded bags.

- Unsalted butter. Builds the roux and later gets brushed on the biscuits with garlic for that classic seafood-shack finish.
- Onion, celery, and carrot. The classic mirepoix that gives the filling its savory backbone.
- Garlic. Goes into both the filling and the garlic butter brushed on the baked biscuits.
- All-purpose flour. Thickens the filling into a sauce and forms the base of the biscuit dough.
- Seafood stock or chicken broth. Gives the sauce real flavor instead of leaning on cream alone.
- Half-and-half. Rounds out the sauce and keeps it rich without turning heavy.
- Old Bay seasoning. The seafood-shack blend that ties shrimp and crab together.
- Frozen peas. A pop of color and sweetness against the rich sauce.
- Large shrimp. Cooks fast and stays tender if it goes in near the end.
- Lump crab meat. Sweet, delicate pieces that need only a gentle fold so they stay whole.
- Lemon juice. Brightens the rich filling right before it goes under the biscuits.
- Baking powder. Lifts the biscuits into tall, craggy pieces as they bake.
- Sharp cheddar cheese. Melts into the dough for the biscuit's signature tang.
- Cold buttermilk. Brings the dough together and adds a light tang of its own.

How the Pie Comes Together
- Build the vegetable base. Melt 3 tablespoons butter in a large oven-safe skillet over medium heat, then cook the onion, celery, and carrot for 5 to 7 minutes until softened. Stir in the garlic for 30 seconds until fragrant.
- Make the roux. Sprinkle the flour over the vegetables and stir constantly for 1 to 2 minutes so the raw flour taste cooks off.
- Build the sauce. Slowly whisk in the seafood stock, then the half-and-half, scraping the bottom of the pan. Simmer, whisking often, for 4 to 5 minutes until the sauce thickens enough to coat a spoon.
- Season and fold in the seafood. Stir in the Old Bay, salt, and pepper, then add the peas. Fold in the shrimp, crab, lemon juice, and parsley, and pull the pan off the heat right away. Spread the filling in an even layer in a 9x13-inch baking dish or the same oven-safe skillet.
- Mix the biscuit dough. Whisk the flour, baking powder, garlic powder, and salt in a bowl. Cut the cold butter in with a pastry cutter or your fingers until the mixture looks like coarse crumbs, then stir in the cheddar. Add the cold buttermilk and stir just until the dough comes together. It should look rough, not smooth.
- Top and bake. Drop the biscuit dough over the filling in rough 1/4-cup mounds, leaving a little space between them. Bake at 400°F (200°C) for 22 to 28 minutes, until the biscuits are deep golden and the filling bubbles at the edges. The shrimp should look opaque and firm, with an internal temperature of 145°F.
- Finish with garlic butter. Stir the melted butter with garlic powder and parsley, then brush it generously over the hot biscuits. Let the pie rest for 5 minutes before serving so the filling sets slightly.

Getting a Smooth Seafood Sauce
A roux is just butter, flour, and patience. Melt the butter, cook the vegetables until soft, then stir in the flour and let it cook a full minute before any liquid goes in. Raw flour stirred straight into warm liquid turns a sauce gluey and leaves a pasty taste behind.
Pour in the stock slowly while you whisk instead of dumping it in at once. A slow pour keeps the roux from seizing into lumps. Once that base looks smooth, add the half-and-half the same way. Simmer gently, whisking every minute or so, until the sauce is thick enough to coat the back of a spoon before the seafood goes in.
Why Cold Butter Makes Flaky Biscuits
Cheddar Bay biscuits are a quick bread, so baking powder does the lifting instead of yeast. The rise depends on steam and gas escaping fast once the biscuits hit a hot oven, and that only happens if the butter is still in small cold pieces when the dough goes in.
Cut the butter in until the pieces are pea-sized, not sandy. Those little lumps melt open pockets as the biscuits bake, which is what makes them craggy instead of dense. Stir in the buttermilk just until the dough holds together. Extra mixing develops gluten, and that is what turns a biscuit tough.
Cooking Shrimp and Crab Safely
Shrimp and crab cook fast, and overcooking is the real risk here, not undercooking, since the oven finishes a sauce that is already hot. The FDA advises cooking seafood to an internal temperature of 145°F, until the flesh turns firm and opaque. A quick check with a food thermometer in the thickest piece of shrimp takes out the guesswork.
Keep raw shrimp and crab refrigerated at 40°F or below until you're ready to cook, and get the filling into the oven soon after mixing it. Foodsafety.gov's guidance on handling fish and shellfish also recommends not leaving cooked seafood out at room temperature for more than two hours.
Smart Swaps for This Pie
No crab in the store? Canned lump crab meat works fine here, just drain it well and pick through for shell. Bay scallops or chunks of firm white fish like cod can stand in for some or all of the shrimp, added at the same point so they don't overcook.
For the topping, a boxed biscuit mix stirred with cheddar and a little garlic powder gets you most of the way there if you're short on time. Cooks avoiding dairy can swap the half-and-half for full-fat coconut milk and use a plant-based butter and cheddar, though the sauce will taste a little different.
Make It Ahead and Store Leftovers
Make the filling up to a day ahead and keep it covered in the fridge, then bring it back to a simmer on the stove before topping it with fresh biscuit dough and baking. Baking straight from cold filling just adds a few extra minutes in the oven.
Leftovers keep well covered in the fridge for up to 3 days. The biscuits soften as they sit, but the flavor holds up.
Frequently Asked Questions
- → Can I use frozen shrimp and crab?
Yes. Thaw both in the refrigerator overnight or under cold running water, then pat the shrimp dry before adding it to the filling. Excess water from thawing can make the sauce thinner than it should be.
- → What can I use instead of half-and-half?
Whole milk works, though the sauce will be a little less rich. For a closer match, use low-fat milk and add an extra tablespoon of butter to the roux to make up the difference.
- → Can I use a biscuit mix instead of making the dough from scratch?
Yes. Stir shredded cheddar and a little garlic powder into a boxed biscuit mix prepared according to its package, then drop it over the filling the same way. It won't taste quite as rich, but it saves time.
- → How do I know the shrimp is fully cooked?
The flesh should look opaque and firm rather than translucent and gray. If you want certainty, check with a food thermometer. The FDA recommends cooking shrimp and other seafood to an internal temperature of 145°F.
- → Can I freeze this pie?
The filling freezes well on its own for up to 2 months. Biscuits are best made fresh, so thaw the filling, reheat it on the stove, and bake a fresh batch of biscuit dough on top rather than freezing the assembled pie.
- → What goes well with this seafood pie?
A simple green salad with a sharp vinaigrette cuts through the richness nicely. Crusty bread for mopping up the sauce or a side of roasted green beans both work well too.
- → Can I leave out one of the seafood types?
Yes. An all-shrimp or all-crab version both work, just keep the total seafood weight close to what the recipe calls for so the filling holds the right texture.
