| Red Onion 🧅 | ¼ cup | Finely diced, sharp bite |
| Fresh Dill 🌿 | ¼ cup | Chopped, vibrant flavor |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for brightness |
| Toasted Walnuts 🥜 | ½ cup | Chopped, for crunch |

The mackerel is the star—opt for wild-caught in water for the cleanest flavor. Wild Planet or Raincoast Trading brands are my go-tos for quality. Fresh dill and parsley are non-negotiable here; they brighten the dish and cut through the richness. Toast your walnuts in a dry pan for 2-3 minutes until fragrant—they add a nutty depth that balances the fish. For the dressing, use extra-virgin olive oil you'd drizzle on bread, not the cheap cooking oil. The lemon juice should be freshly squeezed—bottled just won't cut it.
No fresh dill? Dried dill at one-third the amount works in a pinch, but it lacks that bright pop. Swap walnuts for pecans or almonds if you prefer. The red onion can be subbed with shallots for a milder bite. If you're avoiding honey, maple syrup or agave works equally well. For extra crunch, add toasted breadcrumbs or crispy fried shallots. The dressing can be made ahead—just whisk everything together and store it in the fridge for up to 5 days. The greens should be added fresh just before serving to keep them crisp.
This salad keeps beautifully for 3-4 days in the fridge, with flavors deepening over time. Store the dressing and mackerel mixture separately until ready to assemble—this prevents the greens from wilting. For meal prep, portion into glass containers with tight lids. The walnuts stay crunchy for 2 days if sealed properly. Double the recipe and freeze half for later—it thaws perfectly and tastes even better the next day as the flavors meld.

Step-by-step instructions for canned mackerel salad
Here's how to assemble this bright, umami-rich salad in record time.
Flake the Mackerel and Toast the Walnuts
Open the 2 cans of canned mackerel in water and drain them thoroughly. Using your fingers or a fork, gently flake the mackerel into small, even pieces—you want them to distribute evenly throughout the salad without overpowering the greens. Set aside in a medium bowl.
While the mackerel flakes, toast the 0.5 cup toasted walnuts in a dry skillet over medium heat for 3-4 minutes until fragrant and golden. Watch closely—they'll darken quickly. Remove from heat immediately and let cool for 2 minutes before chopping them into small pieces. This toasting enhances their nutty flavor and adds delightful crunch to every bite.
Build the Dressing with Perfect Balance
In a small bowl, whisk together the 0.5 cup extra-virgin olive oil, 3 tbsp fresh lemon juice, 1 tbsp red wine vinegar, 1 tbsp Dijon mustard, and 1 tbsp honey. The lemon juice should brighten immediately, cutting through the richness of the olive oil. Add 0.5 tsp sea salt and 0.25 tsp freshly ground black pepper, mixing until fully combined.
Taste the dressing and adjust—you might want to add a splash more lemon juice if it feels too heavy, or a pinch of salt if the flavors need more depth. This dressing is the heart of your salad, so don't rush this step. The right balance of acidity, sweetness, and salt will make all the difference in the final dish.
Prepare the Vegetable Components
Finely dice the 1 whole celery stalk and 0.25 cup red onion, keeping the pieces small and uniform. This ensures even distribution and prevents any one component from overpowering the salad. Chop the 0.25 cup fresh dill and 0.25 cup fresh parsley separately, then combine all the vegetables in a large mixing bowl.
Add the flaked mackerel and chopped toasted walnuts to the vegetable mixture. Give everything a gentle toss with a wooden spoon, being careful not to break up the mackerel pieces too much. The walnuts will add texture contrast while the celery and onion provide a satisfying crunch that complements the soft greens.
Assemble and Dress the Salad
Arrange the 6 cups mixed greens on a large platter or individual plates. The greens should be spread out evenly, creating a lush base for your salad. Pour the dressing over the greens in a slow, steady stream, allowing it to seep down between the leaves. This ensures every bite gets that perfect balance of flavors.
Using a wide spoon, gently fold the dressed greens with the mackerel-vegetable mixture, being careful not to mash the greens. The salad should look vibrant and inviting, with the deep green of the greens contrasting beautifully against the pale yellow of the dressing and the golden walnuts. Let it sit for 5 minutes before serving to allow the flavors to meld together.
Pro Tips For Making Canned Mackerel Salad
- Drain and Rinse Thoroughly: The water in canned mackerel is salty—trust me, you’ll taste it if you skip this. Dump the fish into a colander, rinse under cold water, and pat dry with paper towels. Wet fish makes the dressing separate, and no one wants a sad, watery salad.
- Whisk the Dressing First: Mix your olive oil, lemon juice, vinegar, and mustard in a bowl before adding the mackerel. This ensures everything emulsifies smoothly—no clumpy bits or oily puddles. Stir like you mean it, then let it sit for 2 minutes so the flavors marry.
- Use Room-Temp Ingredients: Cold mackerel and chilled olive oil make the dressing stiff and unappetizing. Take the fish out of the can 10 minutes early, and let the oil sit out if it’s straight from the fridge. Room temperature = creamier texture, every time.
- Add Acid Gradually: Start with half the lemon juice and vinegar, taste, then adjust. Mackerel’s rich flavor needs balance, and too much acid turns it into a sad, sharp salad. If it’s still bland, a pinch of salt or a drizzle of olive oil fixes it—no need to overcorrect.
Flavor customization for these flavors
Spicy Kick
For heat lovers, add 1 tsp of hot sauce (like Cholula or Tabasco) or ½ tsp of cayenne pepper to the dressing. I like to mix in 1 tbsp of finely chopped jalapeño for a fresh, fiery punch.
The heat contrasts beautifully with the mackerel’s richness, creating a bold, umami-spicy balance. Start with ½ tsp and adjust to taste—this salad can handle serious heat! 🌶️
Mediterranean Twist
Swap the red onion for ¼ cup finely diced cucumber and add 2 tbsp of crumbled feta cheese for a Greek-inspired touch. I also toss in 1 tbsp of chopped kalamata olives and a pinch of oregano to deepen the flavors.
The briny olives and creamy feta elevate the dish into a refreshing, coastal-inspired salad that’s perfect for summer.
Citrus Zing
Boost the brightness by adding 1 tbsp of freshly grated orange zest and 2 tbsp of orange juice to the dressing. The citrus notes complement the mackerel’s umami perfectly, creating a vibrant, refreshing flavor profile.
Pair it with ¼ cup of mandarin orange segments for extra pop and a touch of sweetness that balances the savory fish.
Herb-Forward
For a herbaceous twist, double the fresh dill to ½ cup and add 2 tbsp of chopped mint or tarragon to the dressing. The herbs add a bright, aromatic depth that cuts through the richness of the mackerel.
I also like to finish with an extra sprinkle of chopped chives for a fresh, oniony bite that ties everything together.
Smoky Depth
Add ½ tsp of smoked paprika or 1 tbsp of liquid smoke to the dressing for a smoky, charred flavor. This works especially well with toasted pecans instead of walnuts, as their natural sweetness pairs beautifully with the smokiness.
The result is a rich, complex salad that feels hearty enough for a main dish—perfect for a cozy dinner.
Sweet & Tangy
For a sweeter profile, replace the honey with 2 tbsp of maple syrup and add 1 tsp of grated ginger to the dressing. The ginger adds a subtle warmth that complements the mackerel’s oceanic notes.
Top with ¼ cup of dried cranberries or chopped apple for a sweet-tangy contrast that’s both unexpected and delicious.

Frequently asked questions
Can I use canned mackerel in oil instead of water?
The recipe calls for mackerel in water to keep the dressing light and bright, but you can absolutely use oil-packed mackerel if you prefer. Just drain it thoroughly and rinse with water to remove excess oil. For every can used, reduce the olive oil in the dressing by 1 tbsp to maintain balance. The flavor will be slightly richer, so start with ½ tsp less salt in the dressing.
What if I don't like celery or red onion?
No problem! Swap celery for ½ cup diced cucumber or ½ cup bell pepper for crunch, and replace red onion with ¼ cup finely chopped shallots or ½ cup diced apple for sweetness. The key is maintaining texture contrast—just keep the total volume similar. For example, use ¼ cup cucumber + ¼ cup bell pepper instead of celery.
How do I make this salad more substantial as a main dish?
Turn it into a hearty meal by adding 1 cup cooked quinoa or farro to the base, or serve it with toasted sourdough croutons and a side of garlic roasted potatoes. For extra protein, fold in ½ cup cooked chickpeas or ½ cup crumbled goat cheese. The mackerel's richness pairs beautifully with grains and carbs, making it satisfying enough for lunch or dinner.
Can I prepare this salad ahead of time?
Yes, but store the dressing and mackerel mixture separately from the greens to keep them crisp. Combine everything 30 minutes before serving. The walnuts will stay crunchy for 2 days if stored in an airtight container. For best flavor, assemble the salad within 4 hours of making the dressing—this gives the flavors time to meld without making the greens soggy.
Why does my mackerel salad taste too fishy?
Overpowering fish flavor usually means the dressing needs more acidity. Boost it with 1 extra tbsp of lemon juice or ½ tbsp of red wine vinegar, then taste and adjust. For a milder profile, use 1 tbsp of plain yogurt or mayonnaise in the dressing. Also ensure you're using high-quality canned mackerel—brands like Wild Planet have cleaner, less fishy flavors than generic options.
