How to make Seafood Gratin Bake?


  1. In a medium-sized saucepan, combine seafood mix with white wine. Cook until the wine is evaporated, around 3-5 minutes, and transfer to a holding bow.
  2. Rinse the skillet with water and add butter with the rice of choice. Cook for 3-4 minutes until the rice is tender.
  3. Next stir in and whisk heavy cream, Parmesan cheese, salt, black pepper, grated garlic, nutmeg, and cooked seafood mix. Simmer until the cheese melts, around 3-4 minutes.
  4. Transfer the seafood bake mixture into a baking dish and sprinkle Gruyere cheese on top. Broil the mix for 4-6 minutes until the cheese on top is browned.
  5. Feel free to garnish with some fresh chopped parsley and a sprinkle of red pepper flakes.

  1. I just made this recipe and thought I would pass along an easier way to make it.
    I used riced cauliflower and steamed it in the bag then added softened butter, raw chopped shrimp, because thats what I had, and the rest of the ingredients into one bowl. I then mixed it and put it into a greased pie plate and baked it @325 for about 30-40 minutes. It came out perfectly with way fewer steps. Delicious.

    I am so happy to have found your site. I have found the recipes easy to follow and they are delicious and actually turn out like the pictures! This week I have also made Green Sauce and Meatball Dango Soup, to which I added red pepper flakes, and I am waiting for the Soy Paper from Amazon to try the Bite Size Egg Rolls.

    I love to cook and eating low carb works well for me. Your website is a refreshing change from so many low carb sites. Thank you. Carrie

      Hey Carrie! The reason we cooked it this way is that the frozen seafood, white wine and frozen cauliflower all have moisture that needs to be evaporated via pan frying. Otherwise, the gratin will end up like a soup on the bottom!

      However, if you just use shrimp like you mentioned, you probably could get away with throwing everything together and baking it.

      Glad you found LCA and thanks for your kinds words! Means a lot to us!

  2. Awesome Thanks
