Create the base: Sprinkle in the flour and stir to coat the vegetables, cooking for an additional minute.
Add the broth: Pour in the seafood or chicken stock, stirring constantly. Bring to a simmer for 5-7 minutes until thickened.
Stir in the cream and seasonings: Mix in the heavy cream, Old Bay seasoning, salt, and pepper. Fold in the shrimp and lobster meat, cooking for an additional 3-5 minutes.
Prepare the biscuit dough: In a separate bowl, combine flour, baking powder, garlic powder, and salt. Cut in the cold butter until it resembles coarse crumbs, then stir in the cheese and milk.
Assemble the pot pie: Pour the seafood filling into a greased baking dish, then dollop the biscuit mixture over the top.
Bake to perfection: Bake in a preheated oven at 375°F (190°C) for 20-25 minutes until the biscuit topping is golden brown.
Cool and serve: Allow to cool for a few minutes before serving, garnishing with fresh herbs.
Notes
For a dairy-free version, substitute coconut cream and olive oil. Use fresh seafood for the best flavor.
