Why Consider Alternatives to Canned Tuna?
Canned tuna is a convenient, inexpensive, and protein-rich staple, but it comes with potential drawbacks that lead many to seek alternatives. One of the main concerns is mercury exposure, which is particularly relevant for albacore tuna, as larger, older fish tend to accumulate higher levels. Additionally, some individuals wish to reduce their overall fish consumption for ethical or sustainability reasons, while others simply want to expand their culinary horizons and avoid flavor fatigue. Fortunately, a variety of nutritious options—both from the sea and from plants—can fill the role of canned tuna in salads, sandwiches, and recipes.
Low-Mercury Fish Alternatives
If you still enjoy seafood but want to minimize mercury intake, several smaller fish offer similar convenience with superior nutritional profiles.
Canned Salmon
Often cited as a top alternative, canned salmon is lower in mercury than albacore tuna and is an excellent source of omega-3 fatty acids, which are beneficial for heart and brain health. It can be prepared in much the same way as tuna, from creating salmon salad sandwiches to adding it to pasta dishes or making flaky salmon cakes. Choosing canned wild Alaskan salmon is a sustainable option to prioritize.
Sardines
These tiny, nutrient-dense fish are a powerhouse of nutrition, packing more omega-3s, calcium (from the edible bones), and vitamin D than tuna. With a distinctive, savory flavor, they are perfect for smashing on toast, tossing into salads, or mixing into sauces. Their low position on the food chain also means they have minimal mercury contamination.
Mackerel
Mackerel offers a moist, flaky texture and a milder flavor than sardines, making it a versatile and palatable replacement. It’s another great source of omega-3s and other nutrients, with lower mercury levels than larger fish. Skinless and boneless mackerel in oil or water can be flaked into a salad or made into fish cakes.
Other Tinned Fish
For variety, consider other canned seafood options like herring or smoked trout, which can be mashed into a flavorful spread or added to salads for a boost of protein and healthy fats.
Plant-Based Tuna Substitutes
For those following a vegetarian or vegan diet, or simply aiming for more plant-based meals, several creative ingredients can mimic the texture and savory flavor of tuna.
Chickpeas
Mashed chickpeas, or garbanzo beans, are a classic and highly effective stand-in for tuna salad. When mashed with vegan mayonnaise, celery, and onions, chickpeas achieve a similar flaky consistency. For a fishy taste, incorporate finely chopped nori (seaweed) or a pinch of kelp flakes.
Tofu and Tempeh
Crumbled extra-firm tofu provides a sturdy, protein-rich base that can be seasoned with tamari and seaweed to create a savory, fish-like flavor. Tempeh, made from fermented soybeans, offers an even firmer, more substantial texture with a higher protein count than tofu, and it holds up well when marinated and crumbled.
Jackfruit and Banana Blossom
Young green jackfruit and canned banana blossom can be used to create flaky, textured ‘tuna’ chunks. When marinated and baked, they can replicate a tuna steak-like texture, making them ideal for dishes like vegan 'tuna' melts or poke bowls.

Other High-Protein Replacements
For those not tied to a fish-like texture, plenty of other options can provide a similar nutritional punch.
Canned Chicken or Turkey
Pre-cooked, canned chicken or turkey is a straightforward substitution for tuna salad, offering a lean protein source with a more neutral flavor profile. You can shred it and mix it with mayonnaise or Greek yogurt, herbs, and other vegetables for a quick meal.
Eggs
Hard-boiled eggs are a quick and reliable protein source. A classic egg salad can easily replace a tuna salad sandwich, offering a different texture and flavor while still being a budget-friendly option.
Cottage Cheese and Greek Yogurt
Plain cottage cheese or Greek yogurt can serve as a protein-rich, creamy base for spreads or bowls. Mix them with savory seasonings, chopped vegetables, and herbs for a quick and satisfying lunch. Just be sure to use plain, unsweetened versions.
Legumes and Grains
Lentils, black beans, and quinoa are all excellent sources of protein and fiber. A salad with lentils or black beans can offer a hearty and nutritious meal that can be prepared in advance. Cooked quinoa can also be added to salads for extra protein and texture.
Conclusion
Moving beyond canned tuna opens up a world of new flavors and nutritional benefits. Whether you opt for a low-mercury fish like sardines or salmon, a plant-based alternative such as chickpeas or tofu, or another high-protein option like eggs or canned chicken, you have a wealth of choices to explore. Experiment with different seasonings and techniques to find the perfect replacement that suits your health goals and taste preferences. Diversifying your protein sources is a simple way to create more dynamic and balanced meals.
