This canned mackerel salad recipe transforms shelf-stable fish into a rich, umami-packed dish that takes just 15 minutes to prepare—no cooking required.
The secret lies in balancing the bold, briny flavor of mackerel with bright citrus, fresh herbs, and a touch of creaminess, creating a salad that’s both satisfying and protein-packed.
I developed this recipe after realizing how often canned fish gets overlooked in favor of fresh options, despite its convenience and nutritional benefits.
The beauty of this salad is its versatility—it works as a standalone lunch, a side dish, or even a filling for wraps and sandwiches.
The key is using high-quality canned mackerel (in water or olive oil) and letting the lemon juice and herbs cut through the richness while enhancing the natural depth of the fish.
For texture, I add a mix of crisp vegetables and grains, like farro or quinoa, to round out the dish.
What you’ll end up with is a flavorful, nutrient-dense salad that’s creamy from the mackerel, tangy from the lemon, and fresh from the herbs.
Each bite delivers a perfect balance of protein, healthy fats, and bright acidity, making it a standout dish for pescatarians or anyone looking for a quick, no-fuss meal. The best part?
It keeps well in the fridge for up to 3 days, so you can prep it ahead for busy weekdays.
Serve it chilled with crusty bread or over a bed of greens for a complete meal. Whether you’re meal prepping or craving something different, this salad proves that canned mackerel can be just as impressive as its fresh counterpart. Let’s get started!
Ingredients for canned mackerel salad
Pantry staples meet bold flavors—just 14 ingredients for a protein-packed salad that tastes restaurant-quality.
| Ingredient | Amount | Notes |
|---|---|---|
| Canned Mackerel in Water 🐟 | 2 cans | High-quality, drained well |
| Lemon Juice 🍋 | ¼ cup | Freshly squeezed, no pulp |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | Light, fruity variety |
| Red Onion 🧅 | ½ whole | Thinly sliced, white part only |
| Celery Stalk 🥬 | 2 whole | Diced, crisp texture |
| Fresh Dill 🌿 | ¼ cup | Chopped, stems removed |
| Fresh Parsley 🌿 | ¼ cup | Chopped, flat-leaf preferred |
| Plain Greek Yogurt 🥛 | ½ cup | Full-fat for creaminess |
| Farro 🌾 | 1 cup | Cooked, pearled or whole grain |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground preferred |

| Red Wine Vinegar 🍷 | 1 tbsp | For extra tanginess |
The mackerel is the star, so skip the cheap brands—look for Wild Planet or Raincoast in water or olive oil. The canned kind packs just as much flavor as fresh, but with no prep. I always grab the olive oil-packed version for extra richness, but water works too if you add an extra splash of lemon. Fresh herbs are non-negotiable here—they brighten up the dish and cut through the fish’s boldness. Trader Joe’s has great pre-washed dill and parsley if you’re short on time, but the flavor isn’t the same as fresh. Farro adds hearty texture, but quinoa or bulgur works in a pinch if you’re out.
No capers? Chopped cornichons or pickles give a similar briny punch. Short on fresh herbs? Dried dill at one-third the amount works, but it won’t have the same freshness. The Greek yogurt is key for creaminess—full-fat is worth it here—but if you’re avoiding dairy, vegan yogurt or mashed avocado keeps the texture rich. The red wine vinegar might sound fancy, but any good vinegar (even apple cider) will do. The lemon juice can be bottled if you’re in a hurry, but fresh is always better—Meyer lemons add a subtle sweetness that pairs perfectly.
This salad keeps beautifully for 3 days in the fridge, so it’s perfect for meal prep. Store it in an airtight container with a layer of olive oil on top to keep the herbs fresh. I like to portion it into small jars with a spoonful of farro on the bottom—it stays crisp that way. If you’re making it ahead, hold off on adding the capers and herbs until serving so they stay vibrant. Serve it chilled, and trust me, it’s even better the next day as all the flavors meld together.
Why You’ll Love This Recipe
- Pantry Magic: I swear by this recipe when my fridge is bare—just open a can, squeeze some lemon, and boom. No shopping list, no last-minute grocery runs. The mackerel’s rich umami plays perfectly with the sharp onion and celery’s crunch, and honestly? That’s all you need for something that tastes like you slaved over it.
- Zesty Umami Bomb: The lemon juice cuts through the mackerel’s oiliness like a dream, while the olive oil ties it all together with a silky finish. Between us, the red onion’s bite and celery’s freshness make this salad addictive—it’s the kind of flavor that lingers, even after the last bite. (Yes, even on a Tuesday night.)
- Lunchbox Hero: Pack this for work or school—it’s sturdy enough to survive a lunchbox but still bright and exciting. I’ll be real: my kids actually eat their veggies when it’s tucked into a wrap or spooned over crackers. It’s my go-to for quick lunches that don’t taste like a sad desk meal.
- Budget Win: A single can of mackerel feeds my family for days, and the other ingredients? Basic stuff you already have. No wasted leftovers here—this salad keeps well for up to 3 days, and if it’s gone before then, well, that’s just a win for flavor. (Not the prettiest, but the taste makes up for it.)
Step-by-step instructions for canned mackerel salad
Here’s how to create a bright, protein-rich salad with bold Mediterranean flavors.
Cook the Farro to Perfect Al Dente
Rinse the 1 cup farro thoroughly under cold water to remove any excess starch. In a medium saucepan, combine the farro with 2 cups of water and bring to a boil over high heat. Once boiling, reduce heat to medium-low, cover, and simmer for 25-30 minutes until the farro is tender but still has a slight bite. You’ll know it’s ready when the grains are fully cooked but still hold their shape—like a perfect al dente pasta.
Drain any remaining water through a fine-mesh strainer and transfer the cooked farro to a large mixing bowl. Let it cool slightly while you prepare the remaining ingredients. The warm farro will help release flavors when combined with the other components, creating a cohesive salad rather than a cold one.
Prepare the Umami-Packed Mackerel Mixture
Open the 2 cans of canned mackerel in water and drain them thoroughly, pressing gently on the fish to remove any excess liquid. Using a fork, break the mackerel into small, bite-sized pieces and transfer them to the bowl with the cooled farro. Add the 0.5 cup plain Greek yogurt, 0.25 cup extra-virgin olive oil, and 1 tbsp red wine vinegar to the bowl.
Next, finely chop the 0.5 whole red onion (using only the white part) and the 2 whole celery stalks. Add these to the bowl along with the minced 2 cloves garlic. Stir everything together gently but thoroughly to combine. The mackerel will start to release its rich, oceanic flavor, which pairs beautifully with the tangy vinegar and creamy yogurt. This is where the salad’s signature umami depth comes from.
Add the Bright Herbs and Briny Capers
Chop the 0.25 cup fresh dill and 0.25 cup fresh parsley finely, removing any tough stems. Add these herbs to the bowl along with the chopped 1 tbsp capers. The capers will bring a delightful briny kick that balances the richness of the mackerel, while the herbs add freshness and color. Stir everything together again, making sure the herbs are evenly distributed throughout the salad.
Season with the 0.5 tsp salt and 0.25 tsp black pepper, then add the 0.25 cup lemon juice. The lemon juice brightens the entire dish, cutting through the richness of the mackerel and yogurt. Give the salad one final stir, tasting as you go. You’ll want a perfect balance of flavors—salty, tangy, fresh, and umami. If it needs more acidity, add a splash more lemon juice; if it needs more salt, add a pinch more.
Chill and Serve for Maximum Flavor
Cover the bowl and refrigerate the salad for at least 30 minutes before serving. This chilling time allows all the flavors to meld together beautifully. The farro will absorb the flavors of the mackerel, herbs, and lemon juice, creating a cohesive and delicious bite in every spoonful.
When ready to serve, give the salad one final stir to ensure everything is evenly mixed. The texture should be creamy from the yogurt and mackerel, with a satisfying bite from the farro and crunch from the celery and onion. Serve this salad as a light lunch, a protein-packed side dish, or even as a hearty appetizer with crusty bread. It’s packed with umami flavor and ready in just 15 minutes of active prep time!
Pro Tips For Making Canned Mackerel Salad
- Drain and Rinse Properly: Canned mackerel comes packed in water, which can make your salad taste flat. After draining, give the fish a quick rinse under cold water—this removes excess brine and keeps flavors balanced without overpowering the dish.
- Slice Onion Thinly and Soak: I used to chop red onion into big chunks, thinking it’d soften in the salad. Wrong. Thinly slice it first, then toss with a splash of cold water and lemon juice for 5 minutes—this mellows the bite and keeps it crisp, not mushy.
- Chop Celery Small and Tough: Skip the long sticks. Dice celery into ¼-inch pieces so it blends evenly with the mackerel and onion. If you’re lazy, pulse it in a food processor—but don’t overdo it, or it’ll turn into a paste.
- Mix Dressing Last: Adding olive oil and lemon juice too early turns the celery soggy. Keep the dressing separate until you’re ready to serve, then toss everything together right before eating. The texture stays fresh, and the flavors pop.
Storing and reheating this dish
Fridge Storage Tips
Store your canned mackerel salad in an airtight glass container with a tight-sealing lid. I prefer Pyrex glass containers because they keep the salad fresh longer and don’t absorb odors.
Press a thin layer of extra-virgin olive oil (about 1 tablespoon) over the top before sealing—this creates a protective barrier that preserves the herbs and prevents drying. The salad stays fresh for up to 3 days in the fridge at 40°F or below. 🥫
Freezing for Later
While this salad isn’t ideal for long-term freezing (the farro and herbs can get mushy), you can freeze it for up to 1 month if you prioritize the mackerel and yogurt base. Portion into freezer-safe containers or ziplock bags, leaving ½-inch headspace for expansion.
Thaw overnight in the fridge before reheating—never microwave directly from frozen. The texture will be slightly softer after freezing, but it’s still delicious. ❄️
Reheating Safely
For the best texture, reheat only the portion you plan to eat. Transfer the salad to a microwave-safe bowl and heat on 50% power for 1-2 minutes, stirring halfway. If it looks dry, add 1-2 teaspoons of water or lemon juice to revive the moisture.
For stovetop reheating, warm in a nonstick skillet over low heat for 3-4 minutes, stirring frequently to avoid sticking. Always check the internal temperature reaches 165°F to ensure safety. 🔥
Reviving Day-Old Salad
If your salad has lost its crunch after a day or two, don’t toss it! Add a drizzle of fresh lemon juice (about 1 tablespoon) and a sprinkle of chopped herbs to brighten the flavors.
For extra crunch, toss in ½ cup of diced cucumber or radishes just before serving. The acidity from the lemon helps cut through any staleness, making it taste fresh again. 💫
Portioning for Meal Prep
Divide the salad into small, individual containers (like mason jars) for easy grab-and-go lunches. Layer the farro at the bottom, followed by the mackerel mixture, then top with herbs and lemon juice.
This keeps everything fresh and prevents sogginess. Store in the fridge for up to 3 days, and the flavors will continue to develop beautifully. 📅
Nutrition facts
Frequently asked questions
Can I use canned mackerel in oil instead of water?
Oil-packed mackerel adds extra richness to your salad. Just reduce the olive oil in the recipe by 2 tablespoons to balance the extra fat. The flavor will be even more decadent, but the lemon and herbs will still keep it bright. Drain the fish well to avoid excess oil in the salad.
What if I don’t have farro? What are good substitutes?
No problem! Swap farro for quinoa, bulgur, or even cooked brown rice—all work beautifully. For extra texture, try toasted nuts or seeds (like pine nuts or sunflower seeds) instead. Just ensure your grain is cooked and cooled before mixing.
How do I keep the herbs from getting soggy?
Add fresh herbs and capers right before serving to preserve their crispness. For meal prep, store them separately in a small container and mix them in just before eating. Alternatively, layer the salad in jars with herbs on top—this keeps them dry and vibrant until you’re ready to serve.
Is this salad safe for pregnant women?
Canned mackerel is generally safe in moderation, but pregnant women should check the mercury levels. Opt for low-mercury brands (like Wild Planet) and limit consumption to 1-2 servings per week. Always consult your healthcare provider before eating canned fish during pregnancy.
Can I make this salad without yogurt?
Yes! For a dairy-free version, replace the yogurt with mashed avocado or a vegan yogurt. If you prefer a lighter texture, use extra lemon juice and olive oil to bind the ingredients. The salad will still be creamy and flavorful, just with a slightly different mouthfeel.
