What is Shishamo?

Shishamo is a type of small saltwater smelt native to the northern Pacific Ocean, particularly around the coasts of Hokkaido, Japan. The name literally translates to “willow leaf fish” in Japanese, a reference to its long, leaf-like shape. What makes shishamo unique is that it is typically enjoyed whole, including the head, bones, and roe. The bones are so soft and thin that they become perfectly edible when cooked, offering a pleasant crunch and a boost of calcium.

Shishamo is often compared to other small whole fish like capelin or whitebait, but it has a distinctly richer flavor and a firmer texture. When the female fish are in season, they carry a delicate roe that runs along the belly, adding a wonderful pop of texture. Traditionally, shishamo is grilled over charcoal, but the air fryer has emerged as a brilliant modern alternative that replicates that smoky, crispy result with far less effort.

Why Cook Shishamo in an Air Fryer?

There are several compelling reasons to use an air fryer for shishamo. First and foremost, the air fryer excels at creating a crispy exterior without deep frying. The rapid circulation of hot air dehydrates the surface of the fish quickly, producing the same kind of golden, crackling skin you would get from a grill or a pan, but with significantly less oil.

Another advantage is the ease of clean-up. Unlike pan-frying, which can leave oil splatters across your stovetop, air frying keeps everything contained within the basket. There is no need to flip the fish constantly either, although we do recommend a single flip mid-cooking for even browning. The air fryer also doesn’t heat up your entire kitchen the way an oven would, making it perfect for quick weekday meals. Plus, cooking fish in an air fryer mitigates the lingering fishy odor in your kitchen, since the machine is enclosed.

Finally, the air fryer offers precise temperature control, which is essential for a fish as delicate as shishamo. Whether you prefer your fish lightly done or deeply crispy, you can dial in the exact setting with confidence every time.

Ingredients You’ll Need

One of the best things about cooking shishamo is how few ingredients you need. The fish itself is flavorful enough to shine with just a little salt and lemon. Here is a list of what you will need for a basic air-fried shishamo dish:

• Fresh or frozen shishamo: Depending on your location, you may find these in Asian grocery stores or seafood markets. If using frozen, thaw them thoroughly before cooking.
• Salt: Coarse sea salt or regular table salt works fine. A light sprinkling is all you need.
• Oil spray: A neutral oil with a high smoke point, such as avocado oil, canola oil, or light olive oil. The spray helps the skin crisp up evenly.
• Lemon wedges: For serving, to add a bright, acidic contrast to the rich, savory fish.
• Optional seasonings: Black pepper, shichimi togarashi, or a dash of soy sauce for brushing.

That is the entire grocery list. If you want to keep things traditional, skip the oil altogether and just season the fish with salt. The natural oils in the fish will render out during cooking, helping to crisp the skin.

How to Prepare Shishamo for Air Frying

Proper preparation is the foundation of any great fish dish. Follow these simple steps before you turn on your air fryer.

1. Thaw the Fish Completely

If you are using frozen shishamo, do not rush the thawing process. Place the fish in the refrigerator overnight, or in a sealed bag in a bowl of cold water for about 30 to 40 minutes. Pat each fish dry thoroughly with paper towels. Removing excess moisture is critical because a wet surface will steam rather than crisp in the air fryer.

2. Pat The Fish Dry

Even if your shishamo is fresh, always pat it dry. Pay special attention to the belly cavity and the area around the head. The drier the fish, the better the Maillard reaction will be, which leads to that beautiful golden-brown crust.

3. Season Lightly

Seasoning shishamo is a delicate balance. You want to enhance the flavor without overwhelming the natural sweetness of the fish. Sprinkle a pinch of sea salt over both sides, or simply rub a light layer of salt along the body. If you plan to sauce the fish later, use even less salt. Let the seasoned fish rest for about five minutes at room temperature while your air fryer preheats.

4. Preheat the Air Fryer

Preheating is an important step that many people skip. By preheating your air fryer to 200°C (400°F) for about three minutes, you ensure that the fish hits a hot surface immediately, which promotes crispiness and prevents sticking.

How to Cook Shishamo in Air Fryer? (Step-by-Step Guide)

Now that your shishamo is prepped and your air fryer is hot, let’s dive into the actual cooking process. Follow these steps carefully for perfectly cooked fish.

1. Preheat your air fryer to 200°C (400°F) for 3 minutes.
2. Lightly grease the air fryer basket with a spray of neutral oil. This prevents the delicate fish skin from sticking and tearing.
3. Arrange the shishamo in a single layer in the basket. Make sure the fish are not overlapping. If you are cooking a larger batch, do it in multiple rounds rather than crowding the basket. Overcrowding traps steam and results in soggy fish.
4. Spray the top of the fish with a thin layer of oil. This helps the skin crisp evenly and gives it a beautiful glossy finish.
5. Cook at 200°C (400°F) for 6 minutes. Do not open the air fryer during this initial phase.
6. Flip the fish gently using tongs or a spatula. Be careful not to break them. Shishamo are tender, and the head can detach if you are rough.
7. Cook for another 4 to 6 minutes. Keep a close eye on them during the last two minutes. The fish are done when the skin is golden brown and crisp, and the eyes have turned white and opaque.
8. Remove the fish immediately from the air fryer basket and transfer them to a serving plate. They continue to cook slightly from residual heat, so pulling them out a moment before they look fully done is ideal.
9. Squeeze fresh lemon juice over the top and serve hot.

That is the core method. The total cooking time is typically around 10 to 12 minutes, depending on the size of the fish and the wattage of your air fryer.

Air Fryer Temperature and Time Comparison

Not all air fryers are created equal, and personal preference also plays a role in how you like your shishamo. Below is a comparison table to help you choose the right temperature and time based on your preferred texture.

As a rule of thumb, start with the recommended setting of 200°C (400°F) for 10 to 12 minutes total. Adjust from there based on your air fryer’s performance and how crispy you like your fish.

How to Get Extra Crispy Shishamo

If you love the texture of shishamo that shatters when you bite into it, there are a few tricks you can use to elevate the crispiness factor even further.

• Use a light coating of cornstarch or potato starch. Toss the dried fish in a small amount of starch before air frying. The starch creates an ultra-crisp shell that stays crunchy even after the fish cools slightly. Be sure to shake off any excess starch so you do not end up with a powdery residue.
• Refrigerate the fish uncovered for 30 minutes before cooking. This dries out the surface of the skin even more, which is the secret to maximum crispiness. A dry surface is the single most important factor.
• Increase the cooking time in small increments. If your fish are not as crispy as you would like after the recommended time, add one minute at a time. Just check frequently to avoid overcooking, which will make the flesh dry.
• Do not overcrowd the basket. This cannot be stressed enough. A single layer allows hot air to circulate freely around every fish, ensuring even, all-over crispiness.
• Finish with a brief blast at high heat. In the last minute of cooking, bump the temperature to the maximum setting. This final high-heat blast renders any residual surface fat and crisps up the skin beautifully.

Seasoning Variations to Try

While classic salted shishamo is heavenly on its own, experimenting with different seasonings can add a fun twist. Here are some popular variations to try.

Yuzu Kosho and Soy

Mix a small amount of yuzu kosho paste with a splash of soy sauce. Brush this mixture onto the fish before air frying. The citrusy heat pairs wonderfully with the rich, oily flesh of shishamo.

Garlic Butter

Melt a tablespoon of butter and mix it with minced garlic. Brush this over the fish halfway through cooking. The butter adds richness and helps the skin brown beautifully. Avoid using the butter from the start, as the milk solids can burn at high temperatures.

Shichimi Togarashi

For a spicy kick, sprinkle shichimi togarashi over the fish immediately after cooking. This Japanese seven-spice blend contains chili pepper, sansho pepper, orange peel, sesame seeds, and seaweed, adding layers of complexity.

Lemon Pepper

A simple dusting of lemon pepper seasoning before cooking gives the fish a bright, zesty flavor with just a hint of heat. This is a great option if you are serving the shishamo as a appetizer with drinks.

Miso Glaze

Whisk together a tablespoon of white miso paste, a teaspoon of mirin, and a teaspoon of sake. Brush this glaze over the fish for the final 2 minutes of cooking. The sugars in the miso will caramelize, creating a sweet-savory crust.

What to Serve with Air-Fried Shishamo

Shishamo is incredibly versatile and pairs well with a range of sides. Here are some delicious ways to serve it.

• Steamed rice and miso soup: This is the classic Japanese meal. The subtle flavor of the fish pairs perfectly with the warm, comforting taste of miso soup.
• Pickled vegetables: The acidity of pickles, such as takuan (pickled daikon radish) or cucumbers, cuts through the richness of the fish and refreshes your palate.
• Shredded cabbage: A bed of finely shredded raw cabbage is a traditional garniture for grilled fish in Japan. Lightly dressed with ponzu sauce, it adds a crunchy, refreshing contrast.
• Cold sake or beer: Shishamo is a popular accompaniment to alcoholic beverages in izakayas. A crisp, dry sake or a cold lager works beautifully.
• Grilled vegetables: Air-fry some asparagus, bell peppers, or mushrooms alongside the fish for a complete, healthy meal in one go.

Tips and Best Practices

Here are some extra tips to ensure your air-fried shishamo turns out flawless every time.

• Do not salt too early. Salt draws moisture out of the fish. If you season an hour in advance, the skin will become wet, and the fish may become mushy. Season right before cooking.
• Leave the head on. While some people prefer to remove the head, cooking with it intact adds flavor and helps retain moisture. You can remove it before eating if you prefer.
• Use a fish spatula. A thin, flexible fish spatula makes flipping much easier and reduces the chance of tearing the delicate skin.
• Clean your air fryer basket right away. Fish residue can be stubborn when it dries. Soak the basket in warm soapy water shortly after cooking for effortless cleaning.
• Check your air fryer’s wattage. Higher-wattage fryers (1800W and above) cook faster than lower-wattage ones. If yours is powerful, begin with the shorter end of the cooking time range.
• Let the fish rest briefly. Letting the fish sit for a minute or two before serving allows the juices to redistribute, making the flesh more tender and flavorful.

Common Mistakes to Avoid

Even experienced home cooks can run into issues when air frying fish. Here are the most common mistakes and how to avoid them.

• Overcrowding the basket. This is the number one cause of soggy shishamo. If the fish overlap, the areas in contact with each other remain moist and never crisp. Cook in batches if necessary.
• Skipping the preheat. A cold air fryer will gradually heat up, which means the fish will spend more time steaming before crisping. Always preheat for consistent results.
• Using too much oil. A heavy coating of oil can make the skin greasy rather than crisp. A thin spray is all you need. The fish themselves release oil as they cook.
• Overcooking the fish. Shishamo is delicate, and the flesh can become dry and tough if left in the air fryer too long. Remove them as soon as the skin is golden and crisp.
• Turning the fish too soon. If you attempt to flip the fish too early, the skin will stick to the basket and tear. Let the first side cook for at least 5 minutes before attempting to flip.
• Seasoning too heavily. Shishamo naturally has a slightly salty, briny flavor. Heavy-handed seasoning can make the fish unpalatably salty. Start with a light dusting and adjust later.

How to Store and Reheat Leftover Shishamo

If you happen to have leftovers, which is rare because these little fish are so addictive, here is how to store and reheat them properly.

Storing

Let the cooked shishamo cool to room temperature completely before storing. Place them in an airtight container and refrigerate. They will keep for up to two days. Keep in mind that the skin will lose some of its crispness upon refrigeration, but the flavor remains intact.

Reheating

To reheat, the air fryer is your best friend. Preheat the air fryer to 180°C (360°F) and place the leftover fish in the basket in a single layer. Heat for 2 to 3 minutes, or until warmed through. You may want to give them a quick spray of oil to help restore some of the crispiness. Avoid using the microwave, as it will turn the fish rubbery and soggy.

If you want to keep the fish for longer, you can freeze the cooked shishamo. Wrap them tightly in plastic wrap and then place them in a freezer-safe bag. They will keep for up to one month. Thaw in the refrigerator overnight before reheating in the air fryer.

Frequently Asked Questions

Can I cook frozen shishamo directly in the air fryer?

You can, but the results will not be as good. The thick layer of frost can cause the skin to stick to the basket and steam instead of crisp. We strongly recommend thawing the fish thoroughly and patting them dry before air frying. If you are in a rush and want to cook them frozen, you will need to add about 4 to 5 minutes of cook time and use a higher temperature, but expect a less crispy texture.

Do I need to remove the heads before air frying?

No. In fact, keeping the head on is traditional and helps the fish retain moisture and flavor. Many people eat the head directly, as it becomes crispy and surprisingly tasty. If you prefer to remove it, do so before eating, not before cooking.

Why is my shishamo sticking to the air fryer basket?

Sticking is usually caused by a lack of oil on the basket, or by attempting to flip the fish too early. Always spray the basket lightly with oil before adding the fish, and allow the first side to cook completely before flipping. Using a silicone mat with holes can also help prevent sticking.

Can I use parchment paper in the air fryer?

Yes, you can use perforated parchment paper specifically designed for air fryers. This can help with cleanup and prevent sticking. However, make sure the paper does not cover the entire basket, as it will restrict hot air circulation. Do not use plain parchment paper without holes, as it will blow around and block airflow.

Is shishamo safe to eat whole, bones included?

Absolutely. The bones of shishamo are small, thin, and soft enough to eat safely once cooked. They are a great source of calcium. Just be cautious when serving to very young children, as the tiny bones, while soft, may still pose a minor risk.

How do I know when the shishamo is fully cooked?

The skin should be golden brown and crisp, and the flesh should easily separate from the spine when you poke it gently with a fork. The eyes of the fish will also turn white and cloudy. If you use a thermometer, the internal temperature should read at least 145°F (63°C).

What is the best way to reduce the fishy smell in my kitchen?

The enclosed nature of the air fryer already helps a lot with odor control. To further reduce the smell, add a splash of lemon juice or vinegar before cooking. You can also place a small piece of baking paper with a few drops of lemon essential oil near the air fryer, though not inside it. Ventilating the kitchen with an exhaust fan or open window is also effective.
