Instructions

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