What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Many are pantry staples, with a few fresh touches to keep things bright and tasty.

• For the Base:
  • Dense rye bread (preferably Danish or pumpernickel), sliced thinly — I recommend using a brand like Mestemacher for authentic texture
  • Unsalted butter, softened (for spreading a smooth, rich layer)
• For the Dill Butter:
  • Unsalted butter, softened (adds richness)
  • Fresh dill, finely chopped (the star herb that brightens the butter)
  • Fresh lemon juice (just a splash to wake up the flavors)
  • Salt and freshly ground black pepper, to taste
• For the Topping:
  • Pickled herring fillets (available in jars or tins; I prefer the ones packed in mustard sauce for extra tang)
  • Thinly sliced red onion (adds crunch and sharpness)
  • Hard-boiled eggs, sliced or quartered (optional, for creamy texture)
  • Fresh radishes, thinly sliced (for a peppery crunch)
  • Capers or chopped fresh chives (optional garnish)

If you want to swap dairy, use a dairy-free butter alternative for the butter and dill butter. For gluten-free options, almond or oat bread can work nicely, though the rye’s distinctive flavor is part of what makes this smørrebrød so special.

Equipment Needed

• A sharp serrated knife for slicing the rye bread thinly without squishing it
• A mixing bowl for blending the dill butter
• A small spatula or butter knife to spread butter evenly
• Chopping board for prepping herbs, onions, and radishes
• Optional: A fine grater or microplane if you like zesting lemon for the butter

If you don’t have a serrated knife, a very sharp chef’s knife can do the trick, but be gentle to keep the bread from crumbling. I used to make do with a butter knife when I first started, but trust me, investing in a decent serrated knife is worth it for sandwiches like these.

Preparation Method

1. Prepare the dill butter: In a bowl, combine 4 tablespoons (60 g) of softened unsalted butter with 2 tablespoons of finely chopped fresh dill, 1 teaspoon of fresh lemon juice, and a pinch each of salt and freshly ground pepper. Mix thoroughly until smooth and creamy. (Tip: If your butter is too cold, microwave it in 5-second bursts to soften without melting.)
2. Slice the rye bread: Using a serrated knife, cut the rye bread into thin, even slices about ¼ inch (6 mm) thick. This thickness holds toppings well without feeling too heavy.
3. Butter the base: Spread a thin, even layer of softened unsalted butter on each slice of rye bread. This helps balance the tang of the herring and keeps the bread moist.
4. Spread dill butter: On top of the buttered rye, spread a generous layer of the prepared dill butter. This is where the magic happens, so don’t be shy!
5. Add the pickled herring: Place one or two pickled herring fillets on each slice, depending on size and preference. (Troubleshooting: If your herring is too salty, rinse briefly under cold water and pat dry.)
6. Top with garnishes: Arrange thin slices of red onion, radishes, and hard-boiled eggs over the herring. Add a few capers or sprinkle chopped chives for a fresh finish.
7. Final touches: Optional drizzle of lemon juice or a sprinkle of freshly ground pepper before serving.

This whole prep should take about 20-30 minutes. The key is good, fresh ingredients and layering flavors thoughtfully. You’ll know it’s right when the butter is creamy, the herring pleasantly tangy, and the garnishes add just the right crunch and freshness.

Cooking Tips & Techniques

Making this Danish smørrebrød with pickled herring and dill butter is straightforward, but a few insider tips can take it from good to unforgettable:

• Choose quality rye bread: The bread is the foundation here. Look for dense, slightly sour rye that holds up to wet toppings without falling apart.
• Softening butter matters: Butter that’s too hard won’t spread evenly, and melted butter will make the bread soggy. Aim for spreadable but firm.
• Pickled herring prep: If the herring is too strong for your taste, a quick rinse can mellow it out without losing character.
• Layer thoughtfully: Spread butter first, then dill butter, then toppings. This layering prevents sogginess and balances flavors.
• Don’t overcrowd: Overloading the sandwich can make it messy and hard to eat, so keep toppings balanced.
• Serve immediately: Smørrebrød is best enjoyed fresh; the bread can get soggy if left too long.

When I first tried this, I rushed and piled on too many toppings, and the bread turned mushy. Lesson learned! Taking the time to build each slice carefully makes all the difference. Also, multitasking by boiling eggs while preparing dill butter saves precious time.

Variations & Adaptations

This recipe is pretty flexible, and you can adjust it to suit your tastes or dietary needs:

• Vegetarian Version: Swap pickled herring for marinated grilled mushrooms or smoked tofu slices, paired with the dill butter to keep that fresh herb vibe.
• Seasonal Toppings: In summer, add fresh cucumber slices or radish sprouts for extra crunch and brightness.
• Gluten-Free Adaptation: Use gluten-free rye-style bread or crispbread for a similar texture and flavor.
• Spicy Twist: Add a light spread of horseradish cream or a sprinkle of red pepper flakes for some heat.
• Personal Variation: I once added a touch of smoked paprika to the dill butter for a subtle smokiness that paired beautifully with the herring.

Serving & Storage Suggestions

Serve your Danish smørrebrød chilled or at room temperature for best flavor. Arrange on a wooden board or pretty platter to impress guests visually. Pair with crisp pickles, rye crispbread, or a light salad with mustard vinaigrette.

Leftovers can be stored covered in the refrigerator for up to 24 hours, but the bread may soften. To refresh, toast the bread slices lightly before assembling if you plan to eat later.

Reheat the dill butter gently if solidified, but avoid heating the herring. Flavors actually deepen when chilled overnight, so if you make the dill butter ahead, it will taste even better the next day!

Nutritional Information & Benefits

This Danish smørrebrød recipe is a balanced snack or light meal, rich in protein from the pickled herring and eggs, and packed with healthy fats from the butter. Rye bread provides fiber and complex carbs, making it more filling than white bread alternatives.

Pickled herring is an excellent source of omega-3 fatty acids, which support heart and brain health. Dill adds antioxidants and vitamins, while the lemon juice offers a vitamin C boost. For those mindful of gluten or dairy, easy substitutions make this recipe accessible without sacrificing flavor.

Overall, it’s a nourishing option that blends tradition with wholesome ingredients for a taste that’s both satisfying and beneficial.

If you’re looking for a recipe that’s simple, flavorful, and carries a bit of Scandinavian charm, this Danish smørrebrød with pickled herring and dill butter is definitely worth trying. It’s got that perfect mix of tangy, creamy, and herbaceous notes that make each bite memorable.

FAQs

What is smørrebrød?

Smørrebrød is a traditional Danish open-faced sandwich usually served on rye bread with various toppings like fish, meats, cheeses, and spreads.

Can I use fresh herring instead of pickled?

Fresh herring needs to be cured or pickled first; using it raw isn’t recommended. Pickled herring is key to the authentic flavor and texture here.

How long can I store assembled smørrebrød?

It’s best eaten fresh, but you can store assembled sandwiches in the fridge for up to 24 hours. The bread might get soggy, so for longer storage, keep components separate.

Is there a vegetarian alternative to pickled herring?

Yes! Grilled or marinated mushrooms, smoked tofu, or even roasted beets can be great vegetarian substitutes with similar savory depth.

Can I prepare the dill butter ahead of time?

Absolutely! Dill butter can be made a day ahead and stored in the fridge. This actually helps the flavors meld and intensify.
