🍚 Rice Note

It’s best to utilize Leftover Rice or Day-Old Cooked Rice. This type of rice readily absorbs the creamy sauce, enhancing the overall texture and flavor.

🧀 Cheese Note

When selecting cheese for this recipe, opt for a blend recognized for its exceptional melting characteristics. Gruyere, Mozzarella, Cheddar, or Provolone varieties are all excellent choices.

Essential Kitchen Equipment


☑ Before Getting Started

Before you start cooking, make sure to have a Large Skillet ready. This will provide enough space to reduce the seafood mix and cook the cream sauce effectively.

Step 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.

🦪 Extra Flavor Pro Tip

Step 2 Rinse the skillet with water and add butter with the rice of choice. Cook for 3-4 minutes until the rice is tender.

⚡ Shortcut Pro Tip

You can use the Microwave as a quick hack to Melt The Cheese, but for the finest texture and flavor, the oven is the recommended choice.

🌶️ Garnishing Pro Tip

For a restaurant-quality presentation, garnish with Fresh Chopped Parsley and a sprinkle of Red Pepper Flakes.

Recipe Variations

Transform this recipe by substituting the seafood mix with bacon and cauliflower rice to craft a Bacon Cauliflower Gratin dish. This variation delivers a savory and satisfying twist, with the rich bacon flavor blending seamlessly with the creamy cauliflower rice, all crowned with luscious melted cheese.

Pairing Recommendations

Enhance your Seafood Gratin Bake with a side of green salad dressed in Ginger Salad Dressing or a Broccoli Caesar Salad. These salads provide a refreshing contrast to the creamy gratin, with the zesty dressings adding a burst of flavor. For a comforting pairing, opt for a simple soup like Clam Miso Soup.

  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

    • LowCarbingAsian

      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

  3. Made this today. Was delicious! TY
