If you’ve ever stood in the grocery store canned fish aisle squinting at sustainability labels, wincing at recent price hikes, or just craving something different for your lunch, you’re not alone. More than 60% of regular tuna consumers report looking for swap options, per 2024 seafood industry surveys. That’s why we’ve broken down 10 Alternatives for Tuna that work for every recipe, diet, and budget. Whether you avoid tuna for environmental reasons, allergies, mercury concerns, or you just want to shake up your usual meal rotation, every option on this list has been tested for flavor, texture, and real world use.

Tuna has held its spot as a pantry staple for decades, but it comes with real tradeoffs. Overfishing has collapsed 70% of global wild tuna populations according to the Marine Stewardship Council. Mercury levels in popular canned light tuna have risen 15% over the last 20 years, meaning even occasional eaters are recommended to limit servings to just 2 per month for most adults.

This list isn’t just about replacing one food—it’s about finding options you’ll actually look forward to eating, not just settle for. You won’t find weird untested products here: every alternative works for tuna salad, pasta, melts, wraps, and even sushi preparations. We’ve noted diet restrictions, swap ratios, and best use cases for every pick.

1. Canned Sardines: The Budget-Friendly Omega Powerhouse

Most people write off sardines as too strong, but modern water-packed sardines have a mild, meaty texture almost identical to chunk light tuna when flaked. Unlike tuna, sardines are low on the food chain, so they carry almost no mercury risk at all. You can find them for half the price per ounce of most canned tuna, and they have 3x the omega-3 fatty acids per serving.

When swapping for tuna, always pick water-packed sardines that don’t have added smoke or oil. You can flake them with a fork, squeeze a little lemon, and no one will spot the difference in tuna salad, casseroles, or sandwich melts. Most home cooks report that 82% of taste testers can’t tell sardine salad apart from tuna salad when properly seasoned, per a 2023 home cooking survey.

• Best for: Tuna salad, pasta bakes, sandwich melts
• Serving swap ratio: 1:1 exact swap, no adjustment needed
• Pro tip: Remove the soft bones first if you prefer super smooth texture

Sardines are also one of the most sustainable seafood options on the planet. They reproduce quickly, and fishing for sardines has almost zero bycatch compared to tuna longline fishing. If you’ve only ever tried cheap smoked sardines from your grandpa’s pantry, give the plain water packed versions one shot. You’ll walk away wondering why you ever bought tuna in the first place.

2. Young Green Jackfruit: The Neutral Vegan Swap

Young green jackfruit is the most underrated plant based swap for tuna, and it works far better than you might expect. When unripe, jackfruit has no sweet flavor at all, just a firm, flaky texture that mimics chunk tuna perfectly. It absorbs every seasoning you add, so you can match the exact flavor profile you want.

You can find canned young jackfruit in most grocery stores now, usually near the canned beans or international foods. Always pick versions packed in water or brine, not syrup. Drain it very well, squeeze out excess moisture, and break it apart with a fork before adding your usual tuna mix-ins.

Recipe Type	Swap Rating (1-10)
Tuna Salad	9/10
Tuna Melt	8/10
Pasta Sauce	10/10
Sushi	6/10

Jackfruit is completely allergen free, low calorie, and works for every vegan, vegetarian, or gluten free diet. It is also extremely affordable, costing less than $2 per can at most retailers. The only catch is you need to drain it properly, otherwise you get a watery final product. A few extra minutes squeezing moisture will give you perfect results every time.

3. Atlantic Mackerel: The Heart-Healthy Fish Swap

Atlantic mackerel is often confused with the stronger king mackerel, but this small cold water fish has a mild, buttery flavor that fits almost every tuna recipe. It has a similar firm flake, holds together well during cooking, and has far lower mercury levels than any tuna variety.

Like tuna, mackerel works both cold and hot. You can eat it straight from the can in salads, or bake it into casseroles and patties. It has a tiny bit more natural fat than tuna, so you can cut back on mayonnaise slightly when making salad for the same creamy result.

1. Drain canned mackerel completely
2. Flake with a fork, removing any small bones
3. Add ¾ of your usual mayonnaise amount first
4. Mix in seasoning, taste, and adjust as needed

Atlantic mackerel is classified as a best choice seafood by every major sustainability group. Populations are healthy, and fishing methods have very low environmental impact. If you like tuna but want to cut down on mercury, this is the closest swap you will find in flavor and texture.

4. Seasoned Chickpea Tuna: The Classic Plant-Based Staple

Chickpea tuna is the most popular vegan tuna swap online, and for good reason. Mashed chickpeas have a hearty, substantial texture that stands up to mayo, pickles, and all your usual tuna salad add-ins. It’s cheap, easy to make at home, and most people already have chickpeas in their pantry right now.

You don’t need any special ingredients to make good chickpea tuna. Just drain a can of chickpeas, mash them roughly with a fork, and add your normal tuna salad mix. A tiny splash of soy sauce or nutritional yeast will add that subtle salty depth that people expect from canned fish.

• Perfect for: Cold sandwiches, lettuce wraps, snack bowls
• Prep time: 5 minutes total
• Shelf life: 3 days refrigerated, same as regular tuna salad

This swap works great for meal prep, and it never gets that fishy aftertaste that leftover tuna sometimes develops. It is also high in fiber and plant protein, making it a filling lunch option that will keep you full longer than regular tuna. Even dedicated tuna fans usually enjoy this swap after one try.

5. Canned Pink Salmon: The Familiar Fish Swap

Canned pink salmon is the swap most people already know, but very few use correctly. Most people only think of salmon for patties, but flaked canned pink salmon has almost the exact same texture as solid white albacore tuna. It is slightly milder in flavor, and has a tiny bit more natural oil.

Always pick water packed pink salmon, not red sockeye, for tuna swaps. Sockeye has a much stronger, richer flavor that will stand out. Pink salmon is mild, neutral, and takes seasoning exactly like tuna does. You can use it 1:1 in every single tuna recipe with zero adjustments.

Nutrient	Tuna (3oz)	Pink Salmon (3oz)
Protein	20g	19g
Mercury Level	0.12ppm	0.01ppm
Omega 3	0.2g	1.1g

Canned pink salmon is also one of the most consistent affordable fish options. Prices rarely fluctuate the way tuna prices do, and supply remains steady year round. If you want a swap that feels almost identical to tuna without the downsides, this is your best first try.

6. Hearts of Palm: The Crunchy Light Swap

Hearts of palm are the crisp, mild vegetable that makes an amazing light tuna swap. When shredded, they have a flaky, slightly crunchy texture that works perfectly in tuna salad and cold wraps. They have almost no flavor on their own, so they absorb every seasoning you add.

This is the lowest calorie swap on this entire list. A 3 ounce serving of hearts of palm has just 20 calories, but still feels filling and substantial. It works great for anyone watching calories, or anyone who wants a lighter version of tuna salad that doesn’t feel heavy after lunch.

1. Shred canned hearts of palm with a box grater
2. Squeeze out all excess moisture completely
3. Toss with lemon juice first to remove any canned aftertaste
4. Add your normal tuna salad ingredients

Hearts of palm are sustainably farmed, with almost no environmental impact. They are also completely allergen free, and work for every diet restriction. The only downside is they don’t hold up to heat well, so stick to cold preparations only.

7. Striped Mullet: The Regional Seafood Secret

Striped mullet is the best kept secret among professional chefs looking for tuna swaps. This common coastal fish has a firm, meaty texture that is almost identical to yellowfin tuna when cooked. It has a clean, mild flavor with none of the fishy aftertaste many people dislike.

You can usually find frozen mullet fillets at most fish markets, and canned versions are starting to appear in grocery stores across the country. It works great seared for tuna steaks, baked, or even eaten raw for poke bowls.

• Best for: Tuna steaks, poke bowls, grilled fish tacos
• Cook time: 2 minutes per side for medium rare
• Seasoning tip: Use the exact same seasonings you would use for tuna

Mullet populations are extremely healthy, and it is one of the most underfished popular seafood options available. It also costs roughly one third the price of fresh tuna, making it perfect for weeknight meals. If you regularly cook fresh tuna regularly, this swap will change how you do dinner.

8. Tempeh Tuna Crumbles: The High Protein Vegan Swap

Tempeh is fermented soy cake that makes an amazing savory tuna swap. When crumbled and pan fried lightly, it develops a crispy, chewy texture that mimics cooked tuna perfectly. It has a deep, umami flavor that works great in hot dishes and casseroles.

This is the best swap for anyone who misses hot tuna dishes. It holds up perfectly to baking, frying, and mixing into pasta sauces. It will not fall apart or get mushy the way many plant based swaps do.

Dish	Swap Rating
Tuna Casserole	10/10
Tuna Patties	9/10
Hot Tuna Melts	9/10

Tempeh is high in complete protein, and the fermentation makes it easy to digest. It also has a long shelf life in the fridge, so you can keep it on hand for last minute meals. If you have only ever tried tempeh in boring vegan bowls, this preparation will surprise you.

9. Canned Baby Clams: The Savory Umami Swap

Canned baby clams are the swap for anyone who loves the salty, ocean flavor of tuna. When drained and chopped finely, they have almost identical texture to flaked tuna. They add a rich depth that works perfectly in pasta sauces and seafood salads.

Always pick whole baby clams packed in water, not brine, not smoked or seasoned. You can chop them roughly with a knife, or pulse them once in a food processor for chunk texture. They work as a 1:1 swap for tuna in every cooked recipe.

1. Drain clams very well and pat dry with paper towel
2. Chop to your preferred chunk size
3. Add a pinch of black pepper to cut any briny taste
4. Mix into your recipe as normal

Baby clams have almost zero mercury, and are extremely sustainable. They are also very low cost, and have one of the longest shelf lives of any canned seafood. If you like strong flavored tuna dishes, this is the swap for you.

10. Smoked Trout: The Premium Upgrade Swap

Smoked trout is the premium swap for tuna that feels like a treat, not a compromise. It has a mild smoke flavor, firm flaky texture, and works perfectly in cold salads, sandwiches, and spreads. It is richer than tuna, but still light enough for everyday lunches.

You can find canned smoked trout in most grocery stores now, usually right next to the canned tuna. It works great mixed with a little cream cheese and lemon for a spread, or flaked straight into salad. It has none of the bitter aftertaste that smoked salmon sometimes has.

• Best for: Luxury sandwiches, charcuterie boards, salad toppings
• Swap ratio: ¾ cup trout for every 1 cup tuna
• Pro tip: Remove the skin before flaking for best texture

Smoked trout is low mercury, sustainably farmed in most cases, and has twice the omega 3 levels of tuna. It costs a little more than basic canned tuna, but it feels like a big upgrade for very little extra work. This is the swap you will reach for when you want something special for lunch.

At the end of the day, swapping tuna doesn’t mean giving up the meals you love. Every one of these 10 alternatives for tuna brings something extra to the table, whether that’s lower mercury, better environmental impact, lower cost, or just a fun new flavor. You don’t have to commit to giving up tuna forever either—even swapping one serving a week makes a real difference for ocean health and your own body.

Next time you make your grocery list, pick one option that fits your diet and schedule. Don’t be afraid to adjust seasoning, test different brands, and mess up a batch while you find what works for you. Share this list with anyone who’s tired of staring at the tuna shelf every grocery run, and let us know which swap becomes your new go-to.
