Liège-style meatballs are one of the great classics of Belgian cuisine: large, fluffy meatballs made from beef and pork, topped with a sweet and sour rabbit sauce with Liège syrup, dark beer, vinegar, vergeoise and raisins.
Contrary to what its name may suggest, rabbit sauce does not contain rabbit. It probably takes its name from an old rabbit sauce with prunes, reused to accompany meatballs. Today, it has become inseparable from Liège meatballs, served hot with fries.
In this recipe, the meatballs are first baked in the oven and then reheated in a brown, bright and fragrant sauce. The result is generous, comforting, slightly sweet and salty, and deeply linked to the gastronomy of Liège.

From the creation of meatballs to the Liège-style meatball
Meatballs have an origin that dates back to the time of the Roman empire, when they were prepared by mixing meat, fish and shellfish. The first traces of meatball recipes appear among the Arabs in the tenth century. In Europe, these delicacies were on royal tables as early as the fourteenth century, a time when the consumption of meat was a luxury.
In Liège, the recipe for Boulets is a reflection of a tradition rooted in the history of the city. Liège-style meatballs were already prepared at the beginning of the seventeenth century. Their name refers directly to cannonballs, given their rather large size. At that time, the meatballs were served with an herb and lemon sauce. In the early twentieth century, culinary evolution led them to be accompanied by hot sauces or tomato sauces, the latter remaining a popular option.
What are Liège meatballs?
Liège-style meatballs, also known as Liège cannonballs, are large meatballs from the Liège region of Belgium. They are usually made with a mixture of ground beef and pork, stale bread dipped in milk, onion, egg, parsley, and nutmeg.
What makes them truly recognizable is their rabbit sauce: a brown, sweet and sour and slightly syrupy sauce, prepared with onions, vinegar, dark beer, Liège syrup, vergeoise and sometimes raisins.
Why do we say rabbit sauce?
The creation of rabbit sauce and the legends surrounding this name reveal a fascinating history. Its name, although surprising, does not come from the use of rabbit meat in the sauce recipe.
the Petit traité de la boulette, attributes the creation of this sauce to Madame Géraldine Lapin, née Corthouts, wife of Ernest Lapin, a tax collector in the suburbs of Liège at the turn of the twentieth century. This appellation has its roots in the Liège region, where this delicious speciality is cherished.
It turns out that this attribution is completely false and that Mrs. Rabbit never existed. An article by Pierre Leclerc, from the University of Liège, questions this version. Indeed, the fame of the famous rabbit sauce dates back to the 30s. Its name is said to simply come from the use of leftovers from rabbit prune sauce to drizzle over meatballs.
The recipe for rabbit sauce has evolved over time, and today it is made with ingredients such as onions, vinegar, brown sugar, Liège syrup and raisins, creating a symphony of flavors that goes perfectly with dumplings.
The myths and research surrounding the creation of Liège-style meatballs with rabbit sauce illustrate the mystery surrounding the origin of the name of this emblematic sauce. A culinary history that is intertwined with Liège’s past and continues to arouse the interest of Belgian food lovers.

The role of Liège syrup in rabbit sauce
Liège syrup is the key ingredient in rabbit sauce. It brings fruity sweetness, deep color and a shiny texture. Combined with vinegar, dark beer and vergeoise, it creates that typically Belgian balance between sweet, sour and salty.
The sauce should not simply be sweet: it should remain well balanced, with enough vinegar to awaken the richness of the meat.
How to make soft meatballs?
To obtain soft meatballs, you have to mix two meats: beef for the taste and sausage meat or pork for the fat. Stale bread soaked in milk also helps to soften the stuffing.
Avoid packing the meat too tightly when forming the meatballs. The meatballs should hold together, but remain tender after cooking.
What to serve Liège meatballs with?
Liège-style meatballs are traditionally served with fries. They can also be served with a green salad, applesauce, mashed potatoes or stoemp.
The most important thing is to provide enough sauce: it should coat the meatballs, but also accompany the fries.
The preparation of Boulets à la liégeoise requires simple but cleverly chosen ingredients. At the top of the list, ground beef, often mixed with pork, gives the meatballs a chewy texture and a delicate flavor. Onions, herbs and spices add a touch of freshness. Once the ingredients are assembled, the magic happens in the slow cooking, imbuing the Boulets Liégeois with an unparalleled depth of taste.
The meatballs are then topped with the rabbit sauce, prepared with vinegar, vergeoise, dark beer, veal stock, cork syrup and raisins, then simmered for a few moments to soak up the unique flavors of the sauce.
The Boulets Liégeois harmonize perfectly with typical Belgian accompaniments. Crispy fries, stoemps (mashed potatoes and vegetables), and the famous sweet applesauce are classic choices.
