Authentic Danish dark rye sourdough bread “Rugbrød”

Being a Norwegian with a Danish wife can be challenging. Like you can’t get proper Danish rye bread in Norway. There are bakeries that have something they call Danish rye – but it’s not. Usually not even close. Or it’s dry and dense AF.

So I took the challenge, and have perfected my recipe. Oh the things I do for a happy marriage!

(Danish “Kartoffelmad” – leftover potatoes, chives, pink peppercorn, Maldon salt.)

Joking aside, there’s something extremely satisfying about this style of bread. The deep, nutty flavors from the rye pairs so well with aged cheeses, home made smoked cheese, patés or rilettes – and the crutons and crumbles you can make with this bread? The Danes love this bread so much they even put it in their cakes!

NOTE: Below is the basic recipe, plus several variations, tips and tricks to truly tweak this very versatile style to your own taste. The basic recipe is what you’d would use for the truly magnificent Rugbrødslagkage.

Ingredients basic recipe:

  • 200 g coarse whole grain dark rye flour (Sammalt rugmel grov)
  • 200 g white rye flour (siktet rug)
  • 100 g wheat flour
  • 1.5 tbsp non-diastatic dark malt flour (alternatives below)
  • 15 g salt
  • 400 g water
  • 200 g sourdough starter (100 % hydration)

Don’t have a sourdough starter?

If you don’t have a sour dough starter, use 100g more liquid, 100g more plain wheat flour and 3g dry yeast. Ferment in fridge for 24h.

Sourcing ingredients

I realize sourcing some of the ingredients can be hard outside Scandinavia, but here are a few tips.

The Danes some times use something called “knekket rug”, which are whole rye kernels. These are soaked minimum overnight to soften. I can’t get them in Norway, so I use sunflower seeds instead. Unless we’re making the cake. Then I use no seeds at all.

If you can’t find non-diastatic dark malt flour, use a porter or stout instead of water. Make sure it’s a very low IBU variety, not a US style «hop bomb», or it could make your bread bitter.

Alternatively, and honestly the best alternative, go to a home brew store, pick up some brown malt (500g goes a looong way) and ask them to mill it as fine as possible. (Or you could toss it in a powerful blender back home and blitz it to a fine powder)


The high hydration in addition extremely low gluten and the beta-glucans in the rye means this is a very wet and sticky dough.

Find your scale, measure up all the dry then the wet ingredients into a big bowl and mix it all quickly together with a wooden spoon, or just use your dominant hand.

Then just let it sit in the bowl for 20-30 minutes. This rest will fully hydrate the flour and make the dough easier to handle.

Despite the low gluten it is possible to develop what little gluten there is. I do a few stretches and folds. Alternatively run it in a mixer with a dough hook at the very lowest setting. While it will not resemble a nice, firm wheat dough, it will have a huge impact on texture.

Gather the dough into a ball-ish shape, cover with a lid and let sit overnight to rise.

The next day, transfer directly into your bread form; use a bench scraper and tip it into the form. I like to apply a very thin layer of butter to the form to make sure it doesn’t stick.

Wet your dominant hand and spread and even out the dough. If adding seeds on top, sprinkle it over, and then gently pat the seeds into the dough so they stick. Cover the form with a lid, Bee’s wrap or whatever plastic free alternative you have at hand, and let it rise again.

Bake at 230C for 30 mins


  • Add 100g dried cranberries to the dough
  • Add 1 small grated beetroot to the dough
  • Add 100 g sunflower seeds to the dough – and flax seeds if you like
  • Top the bread with poppy seeds, sesame seeds or pumpkin seeds

Zero waste tip:

  • Will keep very well for 4-5 days, and still be quite good after a week.
  • Also freezes very well
  • Makes great crumbles crisped up in some oil for soups or salads
