This seafood pot pie is one of those dishes that feels like a celebration and a weeknight dinner at the same time. I first stitched this together on a damp March evening when I had leftover cooked lobster from a special dinner and a bag of shrimp in the freezer. The goal was simple: turn those luxury ingredients into something that wrapped them in comfort. The result was a creamy, Old Bay–kissed filling studded with tender shrimp and sweet lobster, finished with a Cheddar Bay biscuit topping that crisps at the edges and stays pillowy in the center. The contrast of the bright, slightly spicy seafood base and the buttery garlic-cheddar biscuits is what keeps everyone reaching for seconds.

What makes this version different from a classic chicken pot pie is the delicate sea-sweetness and the choice of a biscuit topping — inspired by the legendary Cheddar Bay biscuits — rather than a traditional pie crust. The filling is built slowly to develop depth: gentle sweated aromatics, a blond roux to thicken without chalkiness, and a splash of heavy cream to enrich. The biscuits are grated-cold-butter textured and studded with sharp cheddar and herbs, giving you the comforting chew and savory lift you want when you cut into a bubbling casserole of seafood goodness.

Ingredients

• Unsalted butter (for the filling): Use high-quality butter like Plugrá or Kerrygold for depth; it browns slightly to add nuttiness to the aromatic base.
• Garlic & onion: Fresh garlic and a small sweet onion provide aromatic foundation—don’t use dried garlic; the fresh allium gives that immediate savory lift.
• Celery: Diced celery adds texture and savory brightness; look for firm stalks with crisp leaves.
• All-purpose flour: Used twice—first to make a blond roux that thickens the filling, then in the biscuit topping; measure by spooning into the cup and leveling for consistency.
• Seafood stock & heavy cream: Use seafood stock for maximum briny depth; substitute chicken stock if needed. Heavy cream rounds the filling and provides a silky mouthfeel.
• Old Bay seasoning: This is the seafood backbone—adds warmth and complexity; if you don’t have it, use a mix of paprika, celery salt, and a pinch of cayenne.
• Shrimp & lobster: Use 1/2 lb peeled shrimp, deveined, and 1/2 lb cooked lobster meat chopped into bite-sized pieces. Wild-caught or sustainably farmed shrimp and cold-water lobster deliver the best texture.
• Cheddar Bay biscuit topping: All-purpose flour, baking powder, garlic powder, cold grated butter, sharp cheddar, and whole milk combine to create biscuits with flakey layers and a savory crumb. Add chives or parsley for a fresh finish.

Instructions

Prepare the aromatics: Preheat the oven to 425°F. In a 10-inch ovenproof skillet or medium saucepan, melt 2 tablespoons unsalted butter over medium heat. Add 2 minced garlic cloves, 1 small finely chopped onion, and 1 diced celery stalk. Sweat the vegetables until translucent and soft, about 5 to 7 minutes; do not brown. This gentle cooking releases sugars and builds the savory base. Make the thickened base: Sprinkle 2 tablespoons all-purpose flour over the softened vegetables and stir continuously for 1 to 2 minutes to cook off the raw flour taste; you want a blond roux, not dark. Slowly whisk in 1 1/2 cups seafood stock, making sure to eliminate lumps. Bring to a gentle simmer so the liquid starts to thicken. Enrich and season: Stir in 1/2 cup heavy cream, 1 teaspoon Old Bay seasoning, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Simmer for 3 to 4 minutes until the mixture coats the back of a spoon. Taste and adjust seasoning; the cream will mellow the spice so balance accordingly. Add the seafood: Fold in 1/2 pound peeled and deveined shrimp and 1/2 pound cooked lobster meat. Cook gently for 2 to 3 minutes—just until the shrimp turn pink and opaque; avoid overcooking to keep shrimp tender. Remove from heat and stir in 1 tablespoon chopped fresh parsley for brightness. Prepare the biscuit dough: In a mixing bowl, whisk 1 cup all-purpose flour, 1 teaspoon baking powder, 1/2 teaspoon garlic powder, and 1/4 teaspoon salt. Grate 2 tablespoons cold butter into the dry mix and work lightly with a fork until pea-sized lumps appear. Stir in 1/2 cup shredded sharp cheddar and 1 tablespoon chopped chives or parsley if using. Add 1/3 cup whole milk and mix until just combined—if dough seems dry, add up to 1 tablespoon more milk; avoid overworking. Top and bake: Spoon or drop generous biscuit mounds over the hot seafood filling in the skillet, leaving small gaps for steam. Brush biscuit tops with a bit of melted butter if desired. Transfer to the preheated oven and bake at 425°F for 18 to 22 minutes, until biscuits are golden brown and filling is bubbling at the edges. Let rest 5 minutes before serving so the filling thickens slightly.

Storage Tips

Keep the filling and biscuits separate if you plan to store leftovers: transfer the filling to an airtight container and refrigerate for up to 3 days. Store leftover biscuits in a shallow container with a paper towel to absorb moisture and reheat in a 350°F oven for 8 to 10 minutes. For freezing, assemble the pot pie in a freezer-safe dish, cover tightly with plastic wrap and foil, and freeze for up to 1 month. When ready to bake, thaw overnight in the fridge and bake at 425°F, checking that the center reaches a safe 165°F.

Ingredient Substitutions

If lobster is unavailable or you want to reduce cost, substitute additional shrimp or use firm-fleshed crab meat for a similar sweet profile—use lump crab in the same 1/2 pound amount. For a lighter cream, swap half-and-half for heavy cream, but expect a slightly thinner filling; thicken with an extra teaspoon of flour if needed. For a gluten-free version, use a 1-to-1 gluten-free flour blend in both the filling roux and biscuits and monitor biscuit texture since some blends absorb liquid differently.

Serving Suggestions

Serve straight from the skillet or transfer to plates with a wide spoon to showcase the biscuit peaks. Pair with a crisp green salad dressed in lemon vinaigrette to cut the richness, or roasted asparagus with a squeeze of lemon. For wine, choose a bright unoaked Chardonnay, Albariño, or a dry rosé. Top the biscuits with extra chopped parsley or chives for color and freshness right before serving.

Cultural Background

Coastal kitchens from New England to the Mid-Atlantic celebrate seafood pot pies and chowders, often building around local shellfish and seasoned with spice blends like Old Bay—a Maryland-born seasoning that captures celery, paprika, pepper, and mustard notes. The Cheddar Bay biscuit topping is a modern American twist inspired by popular seafood chain biscuits; it blends Southern biscuit technique with coastal seafood traditions to create a hybrid dish that feels both homey and regionally expressive.

Seasonal Adaptations

In spring and summer, lightened versions work well: add fava beans or fresh peas to the filling for bright pops, use half-and-half in place of heavy cream, and scatter fresh dill over the finished pie. In colder months, fold in diced roasted root vegetables like parsnips or Yukon gold potatoes for extra heartiness. For holiday tables, prepare mini pot pies in ramekins using biscuit rounds, which makes elegant individual servings.

Success Stories

Readers have told me they made this for birthdays and small dinner parties, swapping half the cheddar for smoked gouda for a deeper flavor. One friend used leftover lobster from a wedding rehearsal dinner and reported it saved the week: “Everyone thought I’d cooked all day, but the truth is the filling came together in under 30 minutes.” The biscuit topping has become a requested side on its own at several family gatherings.

Meal Prep Tips

Make the filling up to 48 hours ahead and cool completely before refrigerating. Keep biscuit dough chilled and shape into mounds on a parchment-lined tray; cover and refrigerate until ready to bake. If you’re prepping for the week, divide into individual portions in small oven-safe dishes for quick reheating. Label containers with the bake time and temperature so reheating is straightforward for busy evenings.

There’s something deeply satisfying about serving a dish that feels special yet approachable; this pot pie does both. Gather around the table, split the biscuits, and know that a little care—cold butter in the biscuits, a gentle simmer on the filling—goes a long way toward a memorable meal. Make it your own with herbs and accompaniments you love, and don’t be surprised if it becomes a repeat request at your house.
