Instructions
- 1
Make the meatballs
- 2
Mix the minced meat with the onion, garlic, egg, breadcrumbs, mustard, parsley, salt, and pepper.
- 3
Shape into meatballs. Traditionally, Liège restaurants serve **one or two very large meatballs**, depending on appetite.
- 4
For weeknight cooking, I keep mine smaller so they brown faster and cook through quickly.
- 5
Brown the meatballs
- 6
Heat butter or oil in a large pan.
- 7
Brown the meatballs on all sides until they have a nice crust.
- 8
Remove them from the pan and set aside.
- 9
Start the sauce
- 10
In the same pan, melt 1 tbsp butter.
- 11
Add the sliced onions and cook until soft and lightly caramelised.
- 12
Sprinkle in the brown sugar and let it melt into the onions.
- 13
Deglaze and add the stock
- 14
Add the vinegar and scrape up all the browned bits from the pan.
- 15
Stir in the mustard and Liège syrup.
- 16
Pour in the beef stock (and beer if using).
- 17
Add the bay leaf.
- 18
Stir until the syrup dissolves and the sauce looks glossy.
- 19
Simmer and adjust
- 20
Return the meatballs to the pan.
- 21
Cover and simmer gently for 25–30 minutes (less if your meatballs are small, longer if they’re traditional large boulets). Stir occasionally and let the sauce thicken naturally.
- 22
Taste and adjust: more syrup for sweetness, more vinegar for tang, more mustard for depth. The sauce should be sweet‑sour, rich, and velvety.
- 23
Serve with fries or mashed potatoes.
