  1. In a heavy skillet, saute the onion and the pepper in 1/2 cup of butter. Cook until tender. Mix in 1/2 cup of the flour, and cook over medium heat for 10 minutes, stirring frequently. Stir in crabmeat, remove from heat, and set aside.
  2. In a large Dutch oven, bring the water to a boil. Add the shrimp, scallops, and flounder, and simmer for 3 minutes. Drain, reserving 1 cup of the cooking liquid, and set the seafood aside.
  3. In a heavy saucepan, melt the remaining 1/2 cup butter over low heat. Stir in remaining 1/2 cup flour. Cook and stir constantly for 1 minute. Gradually add the milk plus the 1 cup reserved cooking liquid. Raise heat to medium; cook, stirring constantly, until the mixture is thickened and bubbly. Mix in the shredded Cheddar cheese, vinegar, Worcestershire sauce, salt, pepper, and hot sauce. Stir in cooked seafood.
  4. Preheat oven to 350 degrees F (175 degrees C). Lightly grease one 9x13 inch baking dish. Press crabmeat mixture into the bottom of the prepared pan. Spoon the seafood mixture over the crabmeat crust, and sprinkle with the Parmesan cheese.
  5. Bake in the preheated oven for 30 minutes, or until lightly browned. Serve immediately.

A few slight changes (reduced green pepper to 1/2 as I know my family's tastes). I turned the heat off immediately after adding the seafood and removed it after 3 minutes. Then I added some shrimp shells to the cooking water, reduced the seafood cooking water down to 2 cups, to make a more concentrated broth, strained it and used all of that and cut back on the milk called for by 1 cup. (thus 2 cups milk/2 cups reduced seafood broth... resulting in a much more veloute-like and less bechamel-like sauce) Using Monterey Jack cheese, much lighter in flavor, also created an overall lighter taste to the dish, without overpowering the seafood. I omitted the flounder and added more scallops. Next time I will try monkfish, which has a texture very much like lobster and holds together nicely when cooked. Since many have mentioned how good it tastes leftover/reheated, I made this in the morning, chilled it, brought it to room temp. prior to reheating and made my and my guests dinner experience much more relaxed. I served it over white rice along with lightly steamed asparagus and passed warmed homemade bread. Yummy!

Okay..what did I do wrong? It was horrible and I was really disappointed after spending so much money on it. I used the canned Phillips crabmeat and I also omitted the fish but followed the recipe exactly. I think the Cheese did not go well with the seafood combination. May have been better with a wine sauce instead. I also used the bags of Med. Frozen Shrimp so maybe I should have used all FRESH seafood instead?

I actually wish I could have offered 4 1/2 stars instead of 5 because I would like to make a recommendation that would make it taste even better. My family and I thought it was very good but too pasty. I think if the flour were maybe a 1/4 cup less and cooked for less time then the recipe suggests, it wouldn't come out so pasty like. All in all though, very good. I changed the seafood a little and didn't use fillet bits but 1 lb of shrimp, 1lb of lump crab and 1lb of scallops. I also served it over rice and steamed broccoli. Also, the recipe took more than 20 minutes to prepare...more like 30+ for me because of peeling the shrimp prior to mixing all the seafood with the other ingredients. It is an expensive dish as other reviews have suggested but it's worth it and definitely something to serve when you have dinner guests.

This was awesome and leftovers were even better! The only changes I did was... instead of water, I used 2 cups clam juice (major flavor booster) and only 2 cups milk. Pretty much followed the main recipe other than that. thanks for sharing a great recipe.

Thoroughly sublime! I'm a seafood fanatic, and this was exactly what I wanted. I do not like flounder, so I used tilapia because I had some in the freezer, and bay scallops because they're smaller and more flavorful. To reiterate what others have said, it takes longer than 20 minutes, I'd allow an hour for preparation plus 30 minutes bake time. I had no trouble with the sauce at all, it turned out very rich, creamy and silky smooth, and I used 1% milk. It takes about 15 minutes to get the onion and pepper caramelized properly, and about 10 minutes simmer for the white sauce before adding the cheese, etc. Keep stirring, and it will thicken! A basic knowledge of making roux is the key to good sauce. I used 3 cans of crabmeat, not fresh. I served with homemade garlic basil breadsticks, a tossed salad, and white wine. Superb! Thanks for sharing ;-)

Great recipes! I cut the recipes in half for just the two of us, turned out real well. I served it with yummy cheddar biscuits (like the ones at Red Lobster), perfect!!! Here's the recipe for the cheddar biscuits... (makes about 8 biscuits) 2 cups Bisquick® baking mix 2/3 cup milk 1/2 cup shredded sharp cheddar cheese 1/4 cup butter - melted 2 cloves of garlic - minced 1 tbsp fresh parsley 1/2 tsp salt -Combine Bisquick®, milk, and cheddar and beat with a wooden spoon for about 30 seconds. -Spoon on to greased cookie sheet. Smooth tops down with spoon. -Bake in 450 degree oven for 8 minutes. -Combine butter, garlic, parsley, and salt. Brush the mixture over top of the biscuits before serving.

I'm giving this 5 stars even tho I didn't follow recipe because I'm sure it would be great as is. Did the crust part as in recipe, then used 2 8 oz. bottles of clam juice and 1/2 cup white wine for liquid instead of water.Used 1-1/2 lb. shrimp, 1 lb. scallops. 12.oz flounder, 1 lb.lobster chunks for seafood,(used more seafood because a lot of people said it was runny),used 2 cups heavy cream, and the liquid I cooked seafood in.Used 1 cup parmeasan cheese,4 oz. cream cheese,1 cup 3 cheese blend (mozz.cheddar, provolone).Used white wine vinegar and left out salt.It came out out of this world every one at Easter loved it, (20)people. Cooked each seafood ingedient separatly since I didn't use the 4 cups of water so they would cook evenly, just took them out of liquid, returned to boil and put the next one in, just took a few min. longer and eack seafood was cooked perfectly.

Excellent! I recommend using only the freshest seafood and only real crab meat. We had it with angel hair pasta and a spinach salad. Yes, it is expensive, but good seafood makes all the difference. And, it is still cheaper than eating in a restuarant! My whole family (inlcuding my 2 year old and 3 1/2 year old) finished their plates, and my husband had 2 huge servings. It takes alot of work, so definitely give yourself the extra time, but it is well worth it. I rate it 5 stars for a home cooked meal. It isn't a 5 star quality restuarant meal, but I'm not a 5 star restaurant chef, and it is one of the best things I've ever made at home.
