Ingredients for canned mackerel salad
Pantry staples meet bold umami in this protein-packed, zero-waste salad masterpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| Canned Mackerel in Water 🐟 | 2 cans | Drained, flaked by hand |
| Mayonnaise 🥫 | ½ cup | Full-fat for creaminess |
| Celery Stalks 🧅 | 3 whole | Thinly sliced, crisp |
| Red Bell Pepper 🍅 | ½ cup | Diced, seeds removed |
| Red Onion 🧅 | ¼ cup | Finely diced |
| Fresh Dill 🌿 | ¼ cup | Chopped, stems removed |
| Lemon Juice 🍋 | 2 tbsp | Freshly squeezed |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For finishing |
| Capers 🍅 | 1 tbsp | Chopped, optional |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | Adjust to taste |
| Freshly Ground Black Pepper 🌶️ | ¼ tsp | Freshly cracked |
| Crusty Bread 🍞 | ½ lb | Sliced for serving |
| Avocado 🥑 | ½ whole | Optional, sliced |
The mackerel is the star, so opt for high-quality brands like Wild Planet or Ocean's Pride—they pack the most flavor. Trader Joe's and Whole Foods carry excellent options, or check the international aisle at your local grocery store. Always drain the cans thoroughly and flake the fish by hand for the best texture. Fresh dill is non-negotiable here; the grocery store variety works, but farmers market dill has that extra punch. Red bell peppers should be vibrant, not wilted—look for firm, glossy ones at the store. For maximum crunch, slice the celery and red onion just before mixing everything together.
No capers? Substitute with chopped cornichons or pickled jalapeños for a tangy kick. Swapping mayo for Greek yogurt cuts calories but loses creaminess—stick with full-fat mayo for authentic texture. Avocado optional but worth it for richness; choose ripe but firm Hass avocados that yield slightly to gentle pressure. The lemon juice can be bottled in a pinch, but freshly squeezed brightens the dish dramatically. For extra umami depth, add a teaspoon of soy sauce or fish sauce to the dressing. The salad keeps its crunch best when assembled right before serving, but the dressing can be made ahead and stored for up to 3 days in the fridge.
This salad thrives on freshness—store components separately until ready to assemble. The mackerel can be flaked and mixed with dressing up to 2 days ahead; keep it chilled. Vegetables should be prepped and stored in airtight containers with paper towels to maintain crispness. The bread pairs beautifully with this dish; toasted sourdough or a rustic baguette elevates it to restaurant quality. Leftovers keep for 3 days in the fridge, though the avocado will soften. For meal prep, pack dressing separately and mix just before eating to preserve texture.

Step-by-step instructions for canned mackerel salad
This umami-packed salad comes together in minutes with no cooking required.
Flake the Mackerel and Mix with Mayonnaise
Open the 2 cans of drained canned mackerel and carefully flake the fish by hand using a fork, removing any large bones. Transfer the flaked mackerel to a large mixing bowl. Add the 0.5 cup mayonnaise and use a wooden spoon to combine thoroughly, breaking up any remaining fish chunks. The mixture should look moist but not watery—this is your base.
Here's the thing—don't rush this step. The texture of your salad depends entirely on how well you break down the mackerel. You want a smooth, paste-like consistency that will blend seamlessly with the other ingredients. If you're concerned about texture, you can press the mixture through a fine-mesh sieve to ensure silky smoothness.
Prepare and Add the Vegetable Components
Thinly slice the 3 whole celery stalks into matchsticks, then dice the 0.5 cup red bell pepper into small, even pieces. Finely dice the 0.25 cup red onion, and chop the 0.25 cup fresh dill, removing any stems. Add all these prepared vegetables to the mackerel mixture and stir gently to combine.
The key here is precision in cutting. The celery should be uniform in size to ensure even distribution throughout the salad, while the bell pepper and onion should be finely diced so they meld rather than remain distinct. Chop the dill last—its bright flavor needs to be fresh when you taste the final product.
Incorporate the Acidic and Briny Elements
In a small bowl, whisk together the 2 tablespoons lemon juice, 1 tablespoon extra-virgin olive oil, and the 1 tablespoon chopped capers. Pour this mixture over the mackerel and vegetable combination, then add the 0.5 teaspoon diamond crystal kosher salt and 0.25 teaspoon freshly ground black pepper. Stir well to distribute all ingredients evenly.
This is where the magic happens—the lemon juice brightens the rich mackerel flavor, while the capers add a briny tang that cuts through the creaminess. The olive oil ties everything together, creating a cohesive texture. Taste as you go—you may need to adjust the seasoning slightly, but the balance should be close to perfect at this stage.
Chill and Rest Before Serving
Cover the bowl with plastic wrap and refrigerate the salad for at least 1 hour, or up to 4 hours if possible. This resting period allows all the flavors to meld together, creating a more harmonious taste profile. The longer it chills, the better the final result will be.
While the salad rests, slice the 0.5 pound crusty bread into thick pieces and toast lightly if desired. If using, halve the 0.5 whole avocado and slice it thinly. These components should be added just before serving to maintain their freshness and prevent the avocado from browning.
Assemble and Serve
When ready to serve, transfer the chilled mackerel salad to a serving platter. Garnish with additional chopped fresh dill if desired, and arrange the sliced avocado on top if using. Serve immediately with the toasted crusty bread on the side for a complete meal.
The final product should be a vibrant mix of textures—creamy from the mackerel and mayonnaise, crunchy from the celery and bell pepper, and fresh from the dill and lemon. Each bite delivers a perfect balance of umami, acidity, and saltiness, making this salad both satisfying and elegant.
Pro Tips For Making Canned Mackerel Salad
- Drain and Pat Dry: The mackerel’s canning liquid is salty and watery—skip pouring it into your bowl. Drain the fish, rinse the fillets briefly under cold water, then blot them dry with paper towels. This keeps the salad from turning into a soggy mess, and the flavor stays sharp instead of muted.
- Julienne the Celery: Don’t just chop the celery into random bits—slice it into thin, even matchsticks (about 1/8-inch thick). The uniform texture makes the salad look polished, and it distributes flavor better when mixed. (Yes, it takes 30 seconds longer, but it’s worth it.)
- Acid Balance First: Add a splash of lemon juice or vinegar before the mayo—about 1 teaspoon—to cut through the mackerel’s richness. Mix it in, then fold in the mayo. This prevents the salad from tasting overly heavy or fishy, especially if you’re using a mild mayo.
- Skip the Raw Onion: If you’re serving the salad immediately, omit the raw red onion—it’ll make your eyes water and overpower the dish. Instead, thinly slice it, soak in ice water for 10 minutes to mellow the bite, then drain before mixing. (Or swap for pickled red onion if you’re feeling fancy.)
Essential equipment for this recipe
Mixing Bowl Essentials
Start with a large glass mixing bowl—I prefer Pyrex because it’s sturdy and non-reactive, preventing any metallic flavors from seeping into your salad. A wooden spoon is ideal for combining ingredients without scratching the bowl.
For flaking the mackerel, use a fork or a fish spatula to gently separate the fish without breaking it into tiny pieces. 🥫
Knife and Cutting Board
A sharp chef’s knife (like Wüsthof or Shun) is a must for clean, precise cuts. Use a cutting board with a non-slip mat to keep ingredients stable while chopping.
For the celery and onion, a mandoline can speed up the process if you’re prepping for multiple servings. Always slice the celery and onion just before mixing to maintain crispness.
Measuring Tools
Accurate measurements matter, especially for the dressing. Use a liquid measuring cup for the mayonnaise and lemon juice, and a small kitchen scale for the capers if you’re feeling precise. A measuring spoon set (like OXO Good Grips) ensures you add the right amount of salt and pepper.
For the olive oil, a small squeeze bottle makes it easy to drizzle evenly.
Storage Containers
If prepping ahead, store components in airtight containers—I recommend Glasslock or Rubbermaid brands. For the dressing, a small mason jar works perfectly, and you can store it in the fridge for up to 3 days.
The mackerel and veggies should go in separate containers to keep everything fresh. Use parchment paper between layers to prevent sogginess.
Serving Essentials
Serve the salad on a large platter or individual bowls for easy portioning. A small serving spoon helps with neat presentation, and a drizzling bottle (like OXO Good Grips) is perfect for adding extra olive oil or lemon juice at the table.
For the bread, a serrated knife ensures clean slices, and a toaster keeps it crispy. 🍽️

Frequently asked questions
Can I use canned mackerel in oil instead of water?
Yes, but you'll need to adjust the recipe slightly. Drain the oil completely and use a paper towel to blot any excess. Since oil-based mackerel is richer, reduce the mayo to ¼ cup instead of ½ cup to avoid heaviness. The extra fat will enhance the umami flavor, so you may also want to increase the lemon juice to 3 tablespoons for balance.
How do I prevent the salad from getting soggy?
Keep all components separate until ready to serve! Store the mackerel-mayo mixture in one container and the vegetables in another. Add the avocado (if using) just before serving. For extra crunch, toss the celery and bell pepper in 1 teaspoon cold water, drain well, and pat dry before mixing.
What's the best way to flake canned mackerel?
Use a fork to gently break apart the fish against the side of the can or bowl. For smoother texture, press the flaked mackerel through a fine-mesh sieve. Avoid using a food processor—it can make the fish too mushy. If you find bones, remove them carefully with tweezers or your fingers.
Can I make this salad ahead of time?
The dressing and mackerel mixture can be prepped 2 days ahead and stored in the fridge. Keep the vegetables separate until serving. For the avocado, add it only when ready to eat. The flavors actually improve overnight as the mackerel's natural oils infuse the dressing.
What are good bread alternatives for serving?
Any crusty bread works beautifully! Try sourdough, baguette, or even rye. For a lighter option, serve with crackers or sliced cucumbers. If you want to make it heartier, add a side of boiled potatoes or quinoa to turn it into a complete meal.
