Method

1. Make the meatballs
2. 1) Mix the minced meat with the onion, garlic, egg, breadcrumbs, mustard, parsley, salt, and pepper.
3. 2) Shape into meatballs. Traditionally, Liège restaurants serve **one or two very large meatballs**, depending on appetite.
4. 3) For weeknight cooking, I keep mine smaller so they brown faster and cook through quickly.
5. Brown the meatballs
6. 4) Heat butter or oil in a large pan.
7. 5) Brown the meatballs on all sides until they have a nice crust.
8. 6) Remove them from the pan and set aside.
9. Start the sauce
10. 7) In the same pan, melt 1 tbsp butter.
11. 8) Add the sliced onions and cook until soft and lightly caramelised.
12. 9) Sprinkle in the brown sugar and let it melt into the onions.
13. Deglaze and add the stock
14. 10) Add the vinegar and scrape up all the browned bits from the pan.
15. 11) Stir in the mustard and Liège syrup.
16. 12) Pour in the beef stock (and beer if using).
17. 13) Add the bay leaf.
18. 14) Stir until the syrup dissolves and the sauce looks glossy.
19. Simmer and adjust
20. 15) Return the meatballs to the pan.
21. 16) 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. 17) 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. 18) Serve with fries or mashed potatoes.
