Chef’s Pro Tips for Perfect Results

To bring out the best in this seafood casserole, keep these tips in mind:

Pat Dry Your Seafood: Moisture is the enemy of browning. Pat your shrimp and scallops dry before cooking for better texture and flavor.
Don’t Overcook the Seafood: Lightly sauté them first, just until opaque. They’ll finish cooking in the oven without turning rubbery.
Use Real Cream: Heavy cream gives the sauce that luxurious, thick finish that makes it irresistible.
Layer for Texture: Place seafood evenly throughout, sprinkle almonds last to retain their crunch.
Let It Rest: Give it a few minutes to settle before serving—it’ll slice better and the flavors will be richer.

Instructions for Making Special Seafood Casserole

Let’s bring all these incredible elements together into one delicious dish. Follow each step carefully and enjoy the process—it’s worth every minute.

Preheat Your Equipment:
Preheat your oven to 350°F (175°C). Grease a 9×13 inch casserole dish and set aside.
Combine Ingredients:
In a large skillet over medium heat, melt the butter. Add garlic and cook until fragrant, about 30 seconds. Stir in flour and cook for 1 minute, then slowly whisk in the cream. Stir constantly until the mixture thickens.
Prepare Your Cooking Vessel:
Once the sauce is thick, remove from heat. Add mozzarella and half of the parmesan. Stir until melted and smooth.
Assemble the Dish:
Gently sauté shrimp and scallops in a separate pan until just opaque, about 2–3 minutes. Combine them with artichoke hearts, then fold into the sauce. Pour the mixture into your prepared casserole dish and smooth the top.
Cook to Perfection:
Sprinkle with remaining parmesan and top with sliced almonds. Bake uncovered for 25–30 minutes until bubbly and golden.
Finishing Touches:
Let the casserole sit for 5–10 minutes after baking to set. This allows the sauce to thicken slightly and the flavors to meld.
Serve and Enjoy:
Scoop generous portions onto warm plates and serve with a simple green salad or crusty bread.
