Ready to create a delectable fusion of East meets West? Here’s everything you’ll need to prepare your Japanese-style macaroni gratin with salmon.

For the Macaroni

  • 2 cups macaroni pasta
  • Water, for boiling
  • 1 tablespoon salt
  • 1 tablespoon vegetable oil

For the Salmon

  • 2 salmon fillets (about 6 ounces each)
  • 1 tablespoon soy sauce
  • 1 teaspoon minced garlic
  • 1/2 teaspoon ground black pepper

For the Bechamel Sauce

  • 2 tablespoons unsalted butter
  • 2 tablespoons all-purpose flour
  • 2 cups whole milk
  • 2 tablespoons white miso paste
  • 1 teaspoon soy sauce
  • 1/4 teaspoon freshly grated nutmeg

For the Garnishing

  • 1/2 cup panko breadcrumbs
  • 1/4 cup shredded mozzarella cheese

Necessary Equipment

To create the delectable Japanese-style macaroni gratin with salmon, you’ll need several key pieces of kitchen equipment. Each item plays a crucial role in ensuring that your gratin cooks evenly and develops the perfect crust and texture. Here’s what you’ll need:

  • Large Pot: To cook the macaroni pasta to al dente perfection. Ensure it’s spacious enough to hold a sizable quantity of water for even cooking.
  • Skillet (or Frying Pan): You’ll use this to sear the salmon fillets and get that delectable golden crust. A non-stick skillet is preferred to avoid any sticking and ensure easy flipping.
  • Medium Saucepan: For preparing your béchamel sauce. The saucepan should have a thick bottom to prevent the sauce from scorching as it thickens.
  • Whisk: Essential for stirring the béchamel sauce smoothly, helping to achieve that silky, lump-free texture.
  • Baking Dish: A good-sized ovenproof dish is necessary for assembling and baking the gratin. Glass or ceramic is ideal for a consistent heat distribution ensuring that your gratin bakes evenly.
  • Mixing Bowls: You’ll need at least two – one for mixing the pasta with the sauce and another for preparing the breadcrumb topping.
  • Cheese Grater: For shredding your mozzarella and Parmesan cheeses. Freshly grated cheese melts better and adds a richer flavor to your gratin.
  • Measuring Cups and Spoons: Precision is key in any recipe, but particularly so when you’re dealing with the delicate balance of flavors in this fusion dish.

Ensure all these items are ready and within reach before you start cooking, to streamline your cooking process and enhance your overall experience making this unique dish.

Preparation Steps

Now that you have all your ingredients and kitchen tools at the ready, let’s dive into the cooking process to bring this Japanese-style macaroni gratin with salmon to life.

Cooking the Salmon

  1. Begin by preheating your skillet over medium heat. Drizzle a bit of olive oil onto the pan.
  2. Take your marinated salmon fillets—remember, these should have been marinating in a mixture of soy sauce and garlic. Place them gently in the skillet.
  3. Sear the salmon for about 4 to 5 minutes on each side or until the exterior is beautifully golden and the inside is cooked through but still moist.
  4. Once done, remove the salmon from the skillet and let it rest for a few minutes. Then, flake it into large chunks using a fork. Set these aside for later use in the gratin assembly.

Preparing the Bechamel Sauce

  1. In a medium saucepan, melt the butter over medium heat. Add an equal amount of flour and whisk consistently for about 2 minutes to cook off the raw flour taste, creating a smooth roux.
  2. Gradually pour in the milk, continuously whisking to ensure the mixture remains lump-free.
  3. Stir in the miso paste, soy sauce, and a pinch of nutmeg. Continue to cook and stir until the sauce thickens to a creamy consistency, which should take about 5 to 7 minutes.
  4. Once thickened, remove the saucepan from the heat. Your béchamel sauce is now ready to be layered into the gratin.

Cooking the Pasta

  1. Fill a large pot with water, add a pinch of salt, and bring it to a boil.
  2. Add the macaroni pasta to the boiling water. Cook according to the package instructions, usually about 8-10 minutes, until al dente.
  3. Drain the pasta well in a colander and then return it to the pot.
  4. Toss the cooked macaroni with a splash of olive oil to prevent the noodles from sticking together. Set aside until you’re ready to assemble the gratin.


Now that your ingredients are prepped and ready, it’s time to assemble your gratin for a beautiful, golden bake.

Layering the Ingredients

Start by preheating your oven to 375°F (190°C). Take a medium-sized baking dish and lightly grease it with a little butter or cooking spray to prevent sticking. Begin your layering by spreading half of the cooked macaroni evenly at the bottom of the dish. Over the macaroni, distribute the seared salmon chunks. Make sure the salmon is evenly spaced to ensure every bite has a generous piece of fish.

Adding the Sauce

Next, pour the miso-infused béchamel sauce over the salmon and macaroni layers. Use a spoon or a spatula to gently spread the sauce, covering the pasta and salmon completely. This rich, creamy sauce will bind all the ingredients together during baking, creating a moist and flavorful gratin.

Final Toppings

Finally, sprinkle the panko breadcrumbs evenly over the sauce-covered layer. Then, scatter a mix of shredded mozzarella and grated Parmesan cheeses on top of the breadcrumbs. These will melt into a golden, delicious crust. Garnish with a bit of chopped parsley for a pop of color and a fresh flavor contrast. Now, your dish is ready to be baked. Slide it into the oven and bake for about 20 to 25 minutes or until the top is golden brown and bubbling. Keep an eye on it to ensure the top doesn’t burn.


Now comes the exciting part where all the flavors combine beautifully in the oven! This is where your dish transforms into a golden, bubbly delight.

Preheat the Oven

Begin by setting your oven to preheat at 375 degrees Fahrenheit (190 degrees Celsius). This is the optimal temperature to ensure that each layer of the gratin heats thoroughly and that the cheese achieves a beautiful, melted consistency. Preheating the oven ensures that your gratin will cook evenly.

Baking Time and Temperature

Place your assembled gratin dish in the center of the preheated oven. Bake the gratin for about 25 to 30 minutes. During this time, the top should turn a lovely golden brown, and the edges should start to bubble vigorously. The high temperature is perfect for getting a nice, crispy topping without overcooking the tender salmon pieces lodged within. Keep an eye on it in the last few minutes to make sure the breadcrumbs and cheese on top don’t burn. Adjust the baking time if necessary depending on your oven’s characteristics and the depth of your gratin dish.

Serving Suggestions

After pulling your Japanese-style macaroni gratin with salmon from the oven, golden and bubbling under a crispy layer of breadcrumbs and cheese, consider complementing its rich flavors with a few thoughtful sides. Here’s how to elevate the entire meal with suitable accompaniments:

  • Pair with a Salad: Balance the creaminess of the gratin with a light, zesty salad. A simple salad with mixed greens, cherry tomatoes, and a light Japanese-style vinaigrette (rice vinegar, a dash of soy sauce, sesame oil, and perhaps a hint of wasabi) will cleanse the palate and add a refreshing contrast.
  • Serve with Pickled Vegetables: Incorporate a traditional Japanese element by serving your gratin alongside some Tsukemono (Japanese pickled vegetables). Quick pickle cucumbers, radishes, or cabbage in rice vinegar, sugar, and a pinch of salt.
  • Add Steamed Vegetables: For a heartier side, offer some steamed vegetables like broccoli, snap peas, or carrots. These can be lightly seasoned with salt, pepper, and a drizzle of sesame oil to continue the East-meets-West theme throughout the meal.
  • Offer Rice on the Side: While macaroni covers the carbohydrate component well, a small bowl of steamed Japanese rice can be a welcome addition for those who desire it, especially to soak up any extra sauce.
  • Pair with Soup: An umami-rich miso soup or a clear soup with seaweed and tofu can provide a warm start to the meal, preparing the palate for the creamy and savory flavors of the gratin.

Each of these sides supports the main dish without overpowering it, ensuring that each bite of the salmon macaroni gratin is as joyful as the last. Remember, the key here is balance and harmony in flavors, creating a meal that will delight and satisfy.

Tips for Perfect Gratins

Achieving the perfect gratin, especially when melding the unique flavors of a Japanese-style macaroni gratin with salmon, can elevate your dish from good to spectacular. Here are some essential tips to ensure your gratin turns out perfectly every time:

Choose the Right Dish

Select a baking dish that conducts heat well, such as a ceramic or glass dish. The size of the dish is crucial; it should be large enough to hold your ingredients without crowding them, allowing each bite to have a delightful crust.

Prep Your Ingredients Properly

Ensure all your ingredients are prepared before you begin layering your gratin. For this dish, cut the salmon into consistent, bite-sized pieces to cook evenly. Cook your macaroni al dente, as it will continue to cook in the oven, absorbing the flavors of the miso béchamel sauce.

Layer Thoughtfully

Start with a layer of macaroni, followed by pieces of salmon, and then pour a generous amount of miso béchamel sauce over the top. Repeat the layers until all ingredients are used. This method ensures each layer melds flavors effectively while baking.

Do Not Overcook the Salmon

Salmon can easily become overcooked and dry out if left too long in the oven. As you preheat your oven and bake the gratin at 375 degrees Fahrenheit (190 degrees Celsius), keep your cooking time within the 25 to 30-minute range to maintain the salmon’s moisture and tenderness.

Achieve the Perfect Golden Topping

The final touch for any gratin is its golden, crispy topping. Mix panko breadcrumbs with a little melted butter or oil before sprinkling over your gratin. This helps achieve a uniformly golden crust. Halfway through baking, check if the top is coloring too quickly and cover it with foil if necessary to prevent burning.

Rest Before Serving

Allow the gratin to rest for a few minutes after removing it from the oven. This resting period helps the layers settle and makes serving easier, ensuring that each portion holds together nicely.


You’re now fully equipped to create a stunning Japanese-style macaroni gratin with salmon that promises to impress both your taste buds and your guests. This delightful dish not only marries the comforting textures and flavors of the West with the subtle umami of Japanese cuisine but also offers a visually appealing and satisfying meal. Whether you’re looking to spice up your dinner routine or serve something unique at your next gathering this gratin is sure to be a hit. So why not give it a try and see just how deliciously different your mealtime can become?
