- Step 7: Place the dish in the preheated oven and bake for 15 to 20 minutes. Monitor closely to avoid overcooking, especially the shrimp, which can become tough if baked too long.
- Step 8: Remove from the oven once the cheese is melted and bubbly and the seafood is cooked through but still tender. Serve warm immediately.
Tips & Variations
- Use a mix of seafood like crab meat or lobster for a more luxurious casserole.
- If you prefer a thicker sauce, simmer the cream with a teaspoon of flour before pouring it over the seafood.
- Add a handful of chopped fresh herbs such as parsley or dill for extra freshness.
- For a bit of heat, sprinkle a pinch of cayenne pepper along with the paprika.
Storage
Store any leftovers in an airtight container in the refrigerator for up to 2 days. Reheat gently in the oven at 325°F (165°C) until warmed through to avoid overcooking the seafood. Avoid microwaving as it can make the shrimp rubbery.
