In this article
Meet Ierbsebulli, a rustic Luxembourgish favourite that turns humble potatoes into something quietly spectacular.

About Ierbsebulli
Ierbsebulli belong to the traditional dishes of Luxembourg and are an irresistible treat for anyone who loves potatoes. These delicious potato dumplings, usually prepared with a hearty filling, make for an exceptionally simple meal that is nonetheless rich in flavour. In Luxembourgish cooking they hold their own both as a main course and as a tasty side dish. Their variety and adaptability make them a highlight on any table.
Ingredients (serves 1–2)
- 500 g potatoes
- 100 g plain flour
- 1 egg
- 50 g bacon (or a vegan alternative)
- 1 onion
- Salt and pepper to taste
- Butter or oil for frying
Shopping for the ingredients
To make Ierbsebulli you need fresh ingredients, all of which are easy to find in any supermarket. When buying the potatoes, pay attention to the variety — floury potatoes work best, as they give a light, fluffy consistency. The bacon, or its vegan stand-in, should be of good quality to bring out the full flavour of the dish. Don’t forget the onions and seasonings as well, so that nothing is missing when you come to cook. The same care with basic ingredients pays off in classics such as Gromperekichelcher.
Preparing the dish
Before you start on the Ierbsebulli, peel the potatoes and cut them into evenly sized pieces so they cook through at the same rate. Finely dice the onion so it distributes evenly through the filling later on. If you are using bacon, chop it into small pieces that will sit neatly inside the dumplings. Allow for the cooking time of the potatoes too, which is usually around 20 minutes until they are soft and tender.
Step-by-step instructions
- Bring the peeled and chopped potatoes to the boil in a pan of salted water and cook for about 20 minutes.
- Fry the onion in a pan with a little butter or oil until translucent.
- Add the bacon if using and fry until it reaches the crispness you like.
- Drain the cooked potatoes, mash them and let them cool.
- Combine the mashed potato thoroughly with the flour, the egg, salt and pepper.
- Shape small portions from the mixture and place a filling of bacon and onion in the centre of each.
- Seal the dumplings well and cook them in a large pan of salted water for about 10 minutes, until they rise to the surface.
- Fry the Ierbsebulli in butter if you like, then serve.
Gluten-free / lactose-free version
For a gluten-free version of Ierbsebulli, use a gluten-free flour blend that binds well in place of wheat flour. Take care to check any filling ingredients for gluten too. For a lactose-free version, plant-based butter or a neutral oil will give the dumplings the richness they need. With these small swaps to the base ingredients the dish stays every bit as delicious and traditional.
Tips for vegans and vegetarians
Vegans can make Ierbsebulli without egg by using a mixture of water and ground linseed as a binder. In place of bacon, smoked tofu cubes or a pinch of smoked salt deliver that same savoury depth. Frying the dumplings in vegan butter adds a lovely finishing note. With these adjustments the dish stays accessible and tasty for every kind of diet — much like the plant-friendly Gromperesalat.
More tips and tricks
One important tip when making Ierbsebulli is to let the potatoes drain thoroughly before mashing them. This stops the mash turning watery and keeps the dumplings at the right consistency. Feel free to experiment with different fillings, such as mushrooms or cheese, to give the dish a personal touch. Take care not to overfill the dumplings, as they can burst open during cooking.
Adapting the recipe to your taste
Ierbsebulli are an extremely flexible dish that is easy to adapt to personal preference. You might vary the seasonings to bring more heat or a more aromatic profile, for example. Many cooks also add herbs such as parsley or chives for extra freshness. With adjustments like these you can create your own signature version of this delicious dish.
Ingredient substitutions
If you have no potatoes to hand, sweet potatoes will give the dumplings a gently sweet note. The bacon can equally be replaced with smoked nut mixtures or other plant-based alternatives to achieve a similar flavour. For a lighter version, swap the flour for potato starch. These alternatives make Ierbsebulli versatile and suitable for a wide range of dietary needs — the same spirit of improvisation that shapes Kniddelen.
Drink pairing ideas
Ierbsebulli go beautifully with a wide range of drinks. A crisp white wine from the region complements the savoury flavours wonderfully. For a non-alcoholic option, a refreshing lemon and ginger spritz balances the richness of the dumplings nicely. A good beer, especially a pale lager, also stands up well to the rustic character of the dish.
Serving and presentation ideas
The presentation of Ierbsebulli can be lifted with attractive dishes and well-chosen accompaniments, such as fresh greenery or a good sauce. Serve the dumplings with a herb butter or a creamy sauce to create both visual and flavour highlights. A fresh salad or some steamed vegetables makes a wonderful addition, on the plate as much as on the palate. That way every meal turns into a small occasion.
A bit of history
Ierbsebulli have their roots in the rural cooking of Luxembourg, where simple, nourishing ingredients came first. Historically they were often prepared for festive occasions, so that friends and family could share a generous meal together. The potato itself only became popular in Europe in the 18th century, which led to the development of countless potato dishes across many kitchens. Today Ierbsebulli are enjoyed not only in Luxembourg but by food lovers worldwide, and they remain a fine introduction to Luxembourgish cuisine.
