Season frozen seafood with salt and pepper. Then cook with butter and set aside. I used already cooked seafood, so do not need to cook.

Cook the pasta according to the package instruction.

Add butter in a pan, cook until melted. Then add in flour, mix well and cook for a minute.

Add in milk, keep stirring. Cook until the sauce thicken to your desire.

Add in pasta and seafood, mix well. Add some parmesan cheese to taste.

Put the pasta in oven-proof dish, sprinkle with shredded mozzarella cheese on top. Pop in preheated oven at 200C , bake for 10-15 minutes or until the top is golden.

Sprinkle some paprika on top, enjoy!
