Scale
For the seafood filling:
- 1 tbsp olive oil or butter
- 1 small onion, finely diced
- 2 celery stalks, diced
- 1 carrot, diced (optional)
- 2 garlic cloves, minced
- ¼ cup all-purpose flour
- 1½ cups seafood or chicken broth
- ½ cup heavy cream or whole milk
- 1 tsp Old Bay seasoning (or ½ tsp paprika + ¼ tsp thyme + pinch of cayenne)
- ½ tsp dried dill or parsley
- Salt & black pepper to taste
- 1 lb (450g) mixed seafood (e.g., peeled shrimp + flaky white fish like cod or halibut, cut into bite-sized pieces)
- ½ cup frozen peas
For the Cheddar Bay biscuit topping:
- 1½ cups (190g) all-purpose flour
- 1 tbsp baking powder
- ½ tsp sugar
- ½ tsp garlic powder
- ½ tsp onion powder
- ½ tsp salt
- ½ cup (1 stick / 115g) cold unsalted butter, cubed
- ¾ cup shredded sharp cheddar cheese
- ¾ cup whole milk
- Optional: extra cheese or parsley for topping
Instructions
- Preheat oven to 375°F (190°C). Grease a 9×13″ baking dish or deep 10-cup casserole.
- Make the filling:
- In a large skillet or Dutch oven, heat oil over medium heat. Sauté onion, celery (and carrot, if using) 5–6 min until soft. Add garlic; cook 30 sec.
- Sprinkle in flour; stir 1–2 min to form a roux.
- Gradually whisk in broth and cream. Bring to a simmer; cook 3–4 min until thickened.
- Stir in Old Bay, dill, salt, and pepper.
- Gently fold in seafood and peas. Cook 2–3 min until shrimp turn pink and fish is just opaque (don’t overcook—seafood will finish baking). Pour into baking dish.
- Make biscuit topping:
- In a bowl, whisk flour, baking powder, sugar, garlic powder, onion powder, and salt.
- Cut in cold butter until mixture resembles coarse crumbs. Stir in cheese.
- Add milk; stir until just combined (do not overmix).
- Assemble & bake:
- Drop biscuit dough by spoonfuls over hot seafood filling.
- Optional: sprinkle extra cheese on top.
- Bake 20–25 minutes until biscuits are golden and filling is bubbly.
- Let rest 5–10 minutes before serving (filling will thicken as it cools).
