  • 3 Cups Cauliflower Rice
  • 2 tbsp Butter
  • 1 Clove Garlic
  • 1 Cup Seafood Mix
  • 1/4 Cup White Wine
  • 1/4 Cup Heavy Whipping Cream
  • 1/4 Cup Grated Parmesan
  • 1/4 tsp Salt
  • 1/8 tsp Black Pepper
  • 1/8 tsp Nutmeg
  • 1/4 Cup Shredded Gruyere Cheese or Mozzarella
  • 1 Stalk Parsley


  • Gather all the ingredients.
  • Preheat oven to broil 500F.
  • Grate garlic with a grater or mince and set aside.
  • In a Teflon frying pan, add frozen seafood mix (does not need to defrost) and white wine. Cook for 3-5 minutes on high heat until most of the liquid has evaporated. Transfer to holding bowl once done.
  • Using the same Teflon frying pan, melt butter over medium heat. Once the butter is melted, stir in the cauliflower and cook until tender, approximately 3 minutes.
  • After 3 minutes, stir in heavy cream, Parmesan cheese, salt, black pepper, grated garlic, nutmeg and cooked seafood mix. Cook for 3-4 minutes until cheese is melted and mixed in thoroughly.
  • Transfer cooked cauliflower rice into a baking dish packing in tightly and sprinkle shredded Gruyere cheese on top ensuring everything is covered. Transfer to oven and bake for 4-6 minutes or until the cheese is melted and golden brown.
  • In the meantime, chop up the parsley. Once the gratin is done, top with chopped parsley and serve hot!
