A smoked mackerel and beet salad bowl takes about 30 minutes and needs only one pot. Hot-smoked mackerel is already cooked, so you boil baby potatoes, slice a few vegetables, and stir together a horseradish yogurt dressing.
I’ll be honest. I avoided beets for years because of the stained cutting boards. Vacuum-packed cooked ones fixed that, and now they sit in my fridge most weeks.
The bowl is smoky. Earthy. Sharp from the horseradish and cool from the cucumber. The potatoes get tossed in dressing while they’re still warm, so they taste seasoned all the way through.
One thing to watch. Add the beets last and keep them in their own spot. Toss them in early and the whole bowl turns pink.

Ingredient Notes
- hot-smoked mackerel: Buy hot-smoked fillets, which are fully cooked and flake easily. Peppered ones work, but they’re saltier. Hot-smoked trout is a good swap.
- cooked beets: Use plain vacuum-packed beets, not the pickled kind. Pickled beets make the dressing too sharp. You can roast 4 medium raw beets at 200 C / 400 F for about 50 minutes instead.
- prepared horseradish: Use the jarred kind, not creamed horseradish sauce. Two tablespoons gives a clear kick. If your jar is mild, add a third.
- plain Greek yogurt: Use 2% or full-fat. Fat-free turns thin and chalky once the lemon goes in. Skyr or sour cream also work.
- baby potatoes: Choose potatoes about 3 to 4 cm wide and halve them. Larger ones need quartering so they cook in the same time.
Smoked Mackerel and Beet Salad Bowl with Dill Yogurt
Ingredients
Method
- Put the potatoes in a 3-quart / 2.8 L saucepan, cover with cold water by 2.5 cm / 1 inch, and add 1 tsp salt. Bring to a boil over high heat, then simmer for 12 minutes, until a knife slides into a potato with no resistance.
- While the potatoes cook, whisk the yogurt, horseradish, olive oil, Dijon, 1 tbsp lemon juice, 1/2 tsp salt, and pepper in a small bowl. It should fall off the spoon in a thick ribbon. Taste and add more horseradish if you want more heat.
- Slice the cucumber, radishes, and red onion. Flake the mackerel into chunks about 3 cm / 1 inch wide, checking for pin bones as you go. Cut the beets into wedges, pat them dry, and keep them separate.
- Drain the potatoes and let them steam dry in the colander for 2 minutes. Toss them with about 3 tbsp of the dressing while they’re still warm.
- Divide the arugula among 4 bowls. Arrange the potatoes, cucumber, radishes, onion, and mackerel in sections, then place the beets last in their own spot. Spoon over the remaining dressing, scatter the capers and dill, and squeeze a lemon wedge over each bowl. Serve within 30 minutes.
Notes
- Buy plain vacuum-packed beets, not pickled, or the dressing turns sharp.
- Salt the potato water well, since the mackerel and capers add salt later.
- Add the beets last and keep them apart to avoid a pink bowl.
- Assemble within 30 minutes of eating so the arugula stays crisp.
Tips for Success
- Start the potatoes in cold, salted water so the centers cook through before the outsides turn mushy.
- Toss the warm potatoes in the dressing first. They absorb the horseradish yogurt as they cool, so every bite tastes seasoned.
- Taste the dressing before you spoon it on. Horseradish strength varies by jar, so add another teaspoon if it doesn’t wake you up.
- Flake the mackerel into chunky pieces and run a fingertip along each fillet to catch any stray pin bones.
- Pat the beet wedges dry on paper towel and place them in the bowls last so they stay ruby instead of staining.
Variations
- Swap the potatoes for 300 g cooked Puy lentils to add fiber and skip the boiling entirely.
- Replace the yogurt with crème fraîche and stir in a spoonful of grated apple for a milder, slightly sweet dressing.
- Add a halved soft-boiled egg to each bowl, cooked 6.5 minutes, for extra protein and a jammy yolk.
Storage and Reheating
Smoked mackerel and beet salad bowls are best assembled fresh, so store the parts separately. Keep the potatoes, beets, flaked mackerel, sliced vegetables, and dressing in separate airtight containers in the fridge for up to 3 days. Once assembled, the bowl holds for about 30 minutes before the arugula wilts and the beets bleed.
Mackerel is a histamine-prone fish, which means it can cause an allergic-type reaction if it’s been stored warm. Keep it refrigerated, eat it by the use-by date, and toss any fish that smells sharp or sour.
Don’t freeze the assembled salad. Cucumber and arugula turn watery once thawed. Nothing here needs reheating, and the potatoes taste fine cold or at room temperature.
Serving Suggestions
Smoked mackerel and beet salad bowls are filling on their own, but a slice of dark rye with salted butter sits right next to them nicely. It catches whatever dressing is left in the bowl.
For a lunch box, pack the arugula and dressing separately and combine at your desk. Kids who balk at fish often eat the potatoes, cucumber, and yogurt first. Let them build their own bowl and add the mackerel in small flakes.
For a drink, cold sparkling water with a lemon wedge or a light lager works. It’s real food doing its thing, with no fuss.
FAQ
Why did my smoked mackerel and beet salad turn pink?
Beet juice is bleeding into the yogurt dressing and potatoes. Pat the wedges dry with paper towel, add them to the bowl last, and keep them in their own spot instead of tossing. A little pink at the edges is normal. A fully magenta bowl means the beets went in too early.
Can I use smoked trout or canned mackerel instead of hot-smoked mackerel?
Yes, use 300 g hot-smoked trout the same way. Canned mackerel in oil also works, but it’s softer and less smoky, so drain it well and add a pinch of smoked paprika to the dressing. Skip peppered mackerel if you’re also using capers, since the bowl gets salty fast.
How do I meal prep smoked mackerel and beet salad bowls for lunch?
Pack the potatoes, beets, mackerel, sliced vegetables, and dressing in separate containers, and they keep for up to 3 days in the fridge. Add the arugula and dressing at lunchtime. Once assembled, the bowl holds about 30 minutes before the greens wilt and the beets stain.
What goes well with a smoked mackerel and beet salad bowl?
Dark rye bread with salted butter is the best match, since it soaks up the dressing and echoes the smoky fish. A cold lager or sparkling water with lemon works as a drink. For a bigger dinner, add a soft-boiled egg to each bowl.
Is a smoked mackerel and beet salad bowl gluten free?
Yes, as written. Mackerel, beets, potatoes, yogurt, and horseradish contain no gluten. Check the labels on your Dijon, prepared horseradish, and smoked fish, because some brands add wheat-based flavorings. Serve it with rye bread only if you’re not avoiding gluten.
What’s the difference between hot-smoked and cold-smoked mackerel for this salad?
Hot-smoked mackerel is cooked through during smoking, so it’s flaky and moist and ready to eat. Cold-smoked fish is cured and silky, closer to smoked salmon, and it won’t flake into chunks. Use hot-smoked here. The pack usually says ‘hot smoked’ or ‘ready to eat’.
