"Kniddelen" with Mustard Sauce

Updated: Sep 27, 2022

"Kniddelen" are a typical Luxembourgish dish, and is usually served with bacon and cream. However, Luxembourg is known for its delicious mustard (the best I have ever eaten) and, thus, for mustard sauce which goes perfectly well with "Kniddelen".

Preparation Time: 10 mins

Cooking Time: 20 mins

Total Time: 30 mins

Servings: 2 people



"Kniddel" dough:

230 g flour

2 eggs

130 ml milk



Mustard sauce:

325 ml milk

80 g mustard (preferably Luxembourgish Original)

15 g grainy mustard (preferably Luxembourgish "à l'ancienne")

1 tsp dried savoury





1. First make the “Kniddel” dough: Sieve the flour into a large bowl and make a well int the middle. Pour the whisked eggs and milk into the well gradually combine with the flour. Season with salt and pepper.

2. In a large pot, heat several litres of water with salt and bring to a boil. Using two spoons take small amounts of dough and slide them into the boiling water. After a few minutes, they will rise to the surface which means your “Kniddelen” are cooked. Use a slotted spoon to transfer them into a different bowl.

3. Meanwhile, whisk the milk with the mustard. Pour the sauce into a pan and heat it on low heat. Add the dried savoury and season with salt and pepper.

4. Add the cooked “Kniddelen” to the sauce and let simmer for 5 minutes while stirring.
