Anyone who loves glazed sushi rolls, smoky grilled fish, or hearty seafood stews knows that eel has a one-of-a-kind buttery, sweet flavor that feels impossible to replicate. But between crashing wild populations, skyrocketing prices, and dietary restrictions, more cooks than ever are searching for workable swaps. That's why we broke down this guide to 8 Alternative for Eel that work for every dish you love.

The International Union for Conservation of Nature reports wild eel populations have dropped 75% globally in just 50 years, classifying most species as critically endangered. Even farmed eel almost always relies on wild-caught baby eels to stock farms, so it does nothing to fix the population crisis. On top of that, good quality eel regularly costs over $30 per pound, putting it out of reach for most weeknight meals.

You don't have to give up the rich, melt-in-your-mouth texture you crave. Every swap on this list matches eel's cooking behavior, flavor profile and mouthfeel. We'll cover exactly which recipes each works best for, how to prep them, and what makes each one a smart choice for your kitchen.

1. Smoked Rainbow Trout

Smoked rainbow trout is the closest match you will find for freshwater unagi eel in both texture and flavor. When cold smoked over apple wood, it develops that same subtle sweet smoke, tender flake, and rich fat content that makes eel so addictive. Unlike eel, most farmed rainbow trout is rated Best Choice by the Monterey Bay Aquarium Seafood Watch, so you can eat it without guilt.

This swap works perfectly for every classic eel dish. You can use it straight on sushi rolls, grill it lightly with teriyaki glaze, toss it into rice bowls, or add it to noodle soups. It holds up to high heat just like eel, and it absorbs sauces exceptionally well without falling apart. Most home cooks will also be happy to learn it costs roughly 60% less per pound than fresh eel at most grocery stores.

For best results when substituting, follow these simple steps:

1. Pat the trout completely dry with paper towels before cooking
2. Brush with a thin layer of mirin 10 minutes before adding glaze
3. Cook over medium low heat, just like you would prepare eel
4. Add a pinch of white pepper at the end to match eel's subtle earthy note

The only difference you will notice is a very mild freshwater fish aftertaste that most people don't even pick up once sauce is added. This is the number one recommended swap for professional sushi chefs who have moved away from serving eel on their menus.

2. Barramundi

Barramundi, also called Asian sea bass, is a firm, oily white fish that has become one of the most popular eel alternatives around the world. It has a neutral base flavor, high fat content, and doesn't flake apart when cooked on a grill or under a broiler. This makes it ideal for the thick glazed grilled eel preparations common in Japanese and Korean cooking.

Farmed barramundi is one of the most sustainable protein sources you can buy today. It produces 5 times less carbon emissions per pound than farmed salmon, and almost 12 times less than wild caught eel. Almost all barramundi sold in North America and Europe is raised in closed recirculating systems that have zero impact on wild fish populations.

Preparation Style	Works For Eel Recipe?	Adjustment Needed
Teriyaki Grilled	Perfect	Cook 2 minutes less per side
Sushi Unagi	Excellent	Add extra smoke powder to glaze
Stew & Braise	Very Good	Cut into 1 inch thick strips
Deep Fried	Good	Use lighter batter

You can find barramundi at almost every major grocery store frozen year round, and it thaws in under 30 minutes right in the package. Many people actually prefer barramundi over eel for regular weeknight meals because it doesn't have the slightly muddy aftertaste that some freshwater eel develops.

3. Smoked Mackerel

Smoked mackerel is a bold, budget-friendly eel alternative that works best for cooked dishes and hearty recipes. It has a higher oil content than eel, which means it stays juicy even when cooked at high temperatures for long periods. You will find it pre-smoked and ready to use at almost every fish counter for less than $8 per pound.

This is not the best pick for plain sushi rolls, but it shines in every other eel application. It works perfectly in grilled skewers, rice bowls, noodle soups, and baked casseroles. The strong smoke flavor stands up perfectly to sweet glazes, spicy sauces, and bold seasonings just like eel does.

When using smoked mackerel remember these key tips:

• Remove the thin silver skin before cooking to avoid a bitter taste
• Use 25% less salt in your glaze than you would for eel
• Cook only until warmed through -- do not overcook
• Pair with acidic sides like pickled ginger to balance the rich flavor

Smoked mackerel is also one of the healthiest options on this list. It contains twice the omega-3 fatty acids of eel, plus high levels of vitamin D and selenium. For quick weeknight meals, this is easily the most convenient eel swap available.

4. Farmed Channel Catfish

Farmed channel catfish is the southern US secret for perfect eel substitutes. It has the same mild, slightly earthy base flavor, dense meaty texture, and ability to absorb every sauce you brush onto it. US farmed catfish is consistently rated sustainable, with strict regulations on water quality and feed.

Many people write off catfish as a cheap low-quality fish, but when prepared correctly it is indistinguishable from eel in blind taste tests. The trick is to avoid breaded pre-processed catfish, and buy fresh whole fillets from the seafood counter. When grilled with teriyaki glaze, even experienced eel eaters rarely notice the difference.

For the most authentic eel texture:

1. Soak fillets in cold salt water for 15 minutes before cooking
2. Score the skin side diagonally every half inch
3. Grill skin side down first for 6 minutes
4. Brush glaze on only during the final 2 minutes of cooking

At an average of $6 per pound, catfish is the most affordable fish alternative to eel on this list. It works for every cooking method, feeds a crowd easily, and holds up perfectly to leftovers for up to three days in the fridge.

5. Black Cod (Sablefish)

Black cod, also called sablefish, is the premium luxury alternative to eel. It has an almost identical buttery, melt-in-your-mouth texture that makes unagi so famous. When smoked or glazed, it has the same subtle sweetness and rich mouthfeel that no other fish can match.

This is the swap that high end restaurants use when they remove eel from their menus. It works perfectly for sushi, sashimi, grilled portions, and fine dining preparations. Black cod has a clean, pure flavor with none of the muddy aftertaste that can come with even high quality eel.

Factor	Black Cod	Wild Eel
Fat Content	19%	18%
Omega 3 per 100g	2100mg	1300mg
Average Price per lb	$18	$32
Sustainability Rating	Good Alternative	Avoid

While black cod is more expensive than other options on this list, it still costs almost half as much as good quality eel. If you are making a special occasion meal or want the most authentic eel experience possible, this is the swap you should choose.

6. Marinated Eggplant

For vegan and vegetarian cooks, marinated eggplant is the best eel alternative you will ever try. When prepared correctly, it develops an almost identical chewy, meaty texture and absorbs glazes perfectly. It has been a standard vegan unagi swap in sushi restaurants for over a decade.

The trick to good eggplant eel is not just the marinade, it is the cooking method. You need to roast the eggplant low and slow first to draw out moisture, then glaze and grill it to get the crispy outside and tender inside that matches eel. Most people are shocked at how convincing this swap is when done right.

To make vegan eel eggplant:

• Cut eggplant into 1 inch thick lengthwise strips
• Salt heavily and let rest 30 minutes, then pat completely dry
• Roast at 325F for 20 minutes to remove remaining moisture
• Brush with unagi glaze and grill on high for 1 minute per side

This swap works perfectly for sushi rolls, rice bowls, and skewers. It costs pennies per serving, works for every diet, and even most omnivores will enjoy it when prepared properly. It is also the only zero mercury alternative on this entire list.

7. King Oyster Mushroom

King oyster mushroom is the second vegetarian eel swap, and it works even better for grilled and braised dishes. It has a dense, chewy meaty texture that is almost identical to cooked eel, with a very mild neutral flavor that takes on any seasoning you add.

Unlike regular button mushrooms, king oyster mushrooms do not get soggy when cooked. They hold their shape perfectly through grilling, frying, braising, and boiling. This makes them ideal for eel stews, fried eel dishes, and street food style skewers.

1. Slice king oyster mushrooms lengthwise into ½ inch thick planks
2. Score the surface in a crosshatch pattern to help glaze soak in
3. Marinate for at least 1 hour in soy, mirin, sugar and smoke powder
4. Cook over high heat until edges get slightly crispy

This swap has become wildly popular in recent years, with many fast casual sushi chains now offering king oyster unagi rolls as a standard menu item. It is low calorie, high fiber, and works for every dietary restriction you might be cooking for.

8. Cured Arctic Char

Cured arctic char is the final eel alternative, and the best option for cold preparations and sashimi style dishes. It sits somewhere between salmon and trout in flavor, with the same fine flake and rich fat content that eel has. When lightly cured and smoked, it is almost indistinguishable from cold eel preparations.

Arctic char is farmed in closed land based systems, making it one of the most sustainable farmed fish available. It has very low mercury levels, consistent quality, and is available year round at most specialty seafood counters.

Cured arctic char works best for:

• Chirashi sushi bowls
• Unagi nigiri
• Cold seafood salads
• Appetizer platters

You can buy pre-cured arctic char or cure it at home in just 24 hours with basic pantry ingredients. It has a cleaner, brighter flavor than eel that many people actually prefer once they try it, and it works perfectly with every traditional eel sauce and side dish.

At the end of the day, you don't have to sacrifice flavor or tradition to make more sustainable, accessible choices at the dinner table. Every one of these 8 alternative for eel has earned its spot on this list by standing up to blind taste tests, working in classic recipes, and fitting a wide range of diets and budgets. Whether you're making sushi for guests, grilling for a backyard cookout, or just craving that rich glazed fish you love, there is a swap here that will work perfectly for you.

Next time you reach for eel at the market or see it on a restaurant menu, try one of these alternatives first. Test a couple different options, play with glazes and cooking methods, and find your new go-to. You might just discover you like the swap even more than the original.
