7 Scandinavian Smorrebrod to Build for Summer Lunch

The first time I ate a proper smorrebrod was at Schonnemann in Copenhagen, a basement lunchroom that has been feeding civil servants since 1877. The waiter set down a slab of rye so dark it looked almost black, a fan of pickled herring, a soft heap of dilled potato salad, and a single caper berry placed like punctuation. He did not call it a sandwich. He called it a piece of bread, and the distinction matters.

Smorrebrod (literally butter-bread) is not a stacked deli sandwich missing its lid. It is an architecture: dense rugbrod base, a thin shield of cold butter, one anchor protein, two or three sharp accents, and a green note on top. Eaten with a knife and fork, never folded. In summer, when Danish gardens throw off radishes, dill, chives, new potatoes, and cucumbers faster than anyone can use them, the whole form gets brighter, lighter, and frankly more interesting than the winter versions weighed down by liver pate.

This list is for the warm months. Build them on a tray, carry them outside, and eat them with cold buttermilk soup or sparkling elderflower cordial.

How I picked these seven

Three rules. First, every sandwich here uses ingredients you can find in a decent supermarket between June and August. No specialty shop required (the one exception is the rye itself, and I will tell you how to fake it). Second, each one belongs to a recognized smorrebrod tradition, drawn from the canon at places like Aamanns 1921, Restaurant Schonnemann, and Selma in Copenhagen, or from the Swedish smorgasbord repertoire. Third, no two share a primary protein. You can build the whole list as a lunch spread for six and nothing will repeat.

What got cut: anything that needs frying at the last minute (sorry, stjerneskud), anything involving liver, and the meat-heavy roast beef with remoulade that belongs to colder weather.

A note on the bread (and butter)

Real Danish rugbrod is a sourdough rye brick studded with whole rye berries, sunflower seeds, and flax. It is sliced thin, around 8 to 10 mm, and it should hold its shape under wet toppings without going soggy for at least 20 minutes. If you cannot find it, look for a German-style vollkornbrot at a good bakery. The pre-sliced Mestemacher loaves sold in the international aisle (the ones in vacuum packs, around $5) are a workable shortcut.

The butter is not optional. Use a good cultured butter, salted, softened just enough to spread but still cold enough to leave a visible layer. It is what keeps the bread from absorbing the topping. Skip it and you have soggy bread in ten minutes flat.

1. Gravlaks with mustard-dill sauce

This is the sandwich I make when I want to impress someone without doing any actual cooking. Salmon cured at home for 48 hours tastes nothing like the supermarket smoked stuff, and the technique is essentially salting a fish and walking away.

The trick most home cooks miss: weight the salmon while it cures. A plate with two cans on top forces the cure into the flesh evenly. After 48 hours in the fridge, scrape off the cure, pat the fish dry, and slice on a long bias as thin as you can manage. One fillet gives you enough for 16 to 20 sandwiches.

Best for: a weekend lunch when you want the centerpiece to look like more work than it was.

2. New potato with chives and smoked mayo

The Danes call this kartoffelmad and it is, against all odds, the lunch smorrebrod that food writers in Copenhagen will tell you is their personal favorite. Waxy new potatoes, boiled in the morning, sliced into coins, layered like fish scales over a smear of smoked-paprika mayonnaise. Simple. Completely satisfying.

Best for: a side piece on a larger smorrebrod platter, or a solo lunch with a glass of cold buttermilk.

3. Pickled herring with red onion and capers

If you only ever make one of these, do not make this one first. It is an acquired taste. But for anyone who already loves the briny, sweet-sour funk of Scandinavian pickled herring, this is the Platonic ideal of summer smorrebrod.

A traditional Copenhagen lunch order is three pieces of sild in a row: matjes, curry, and senneps (mustard). Try at least two styles side by side if you are serving a crowd.

Best for: anyone already fluent in the brine end of the flavor spectrum. Skeptics, start with item 1.

4. Egg and shrimp with lemon mayo

The pinkest sandwich on the list, and the one most likely to convert a skeptic. Cold-water shrimp from the North Atlantic, the kind sold frozen in 200 g bags as raekjur in Iceland or rejer in Denmark, are small, sweet, and need almost nothing done to them.

Best for: a hot day when the kitchen needs to stay cool and lunch needs to be on the table in 15 minutes.

5. Smoked mackerel with horseradish creme

Mackerel is oily, peppery, smoke-friendly, and roughly half the price of salmon. It also pairs better with sharp horseradish than almost any other fish I can think of. This is the sandwich I bring to picnics because it holds together in a tin for the train ride.

Best for: outdoor eating, especially anything involving a blanket on grass. The horseradish does not wilt.

6. Roast beef with crispy onions and pickled cucumber

The outlier. This is the only red-meat sandwich on the list, and it earns its place because cold rare roast beef under quick-pickled cucumber and a heap of crispy onions is one of the great Danish lunchroom orders. It actually gets better on a warm day.

Best for: the one serious-eater at the table who wants something that actually feels like a meal.

7. Radish, cucumber, and dill cream cheese

The simplest, the prettiest, and the one I make most often. Whipped cream cheese with dill, a tile of cucumber, a row of radish coins. Done in five minutes. Looks like it came from a Selma tasting menu.

Best for: weekday lunch at your desk, or as the lightest piece on a larger spread.

Which one to build first

If you have never made smorrebrod before, start with the cream cheese, radish, and cucumber (item 7). It teaches you the proportions: how thin the bread should be, how generous the topping, how the green note on top is not garnish but part of the structure.

If you are building a lunch for four to six people, pick three. One fish (gravlaks or mackerel), one egg or potato (kartoffelmad or shrimp and egg), and one meat or vegetarian closer (roast beef or radish-cream cheese). Make 12 pieces total, two per person, and let people choose.

If you are feeding a skeptic, build the gravlaks. It is the gateway. Almost no one dislikes home-cured salmon, and the mustard-dill sauce is sweet enough to feel familiar.
