Flemish carbonnade in Brussels: the dish that divides Belgians

Flemish carbonnade is beef slow-cooked in brown beer. Nothing more, and that is exactly why it is difficult. The meat must fall apart with a fork, the sauce must be dark and slightly sweet, and the whole thing must hold together without being heavy.

How to recognise a real carbonnade

Three signs never lie. The beef cuts with a spoon, without effort: that is the result of long, gentle cooking, two to three hours at the very least. The sauce is brown and glossy, never watery or floury: it has reduced, it was not thickened in a hurry. And it has a sweet and bitter base that comes from the beer, not from sugar. If the sauce tastes like an ordinary meat gravy, it is not a carbonnade, it is a stew.

The beer is what makes the difference

A Belgian brown ale brings three things at once: malt sweetness, hop bitterness and colour. That combination gives the sauce its character, which is why you cannot replace the beer with wine or stock without changing the dish completely. We let it simmer for a long time and serve it with fries, as it should be. The carbonnade is 22.90 euros on the menu.

Where the dish comes from

Carbonnade takes its name from coal, the Latin carbo: meat cooked slowly over embers, then, over time, simmered in a pot. You find it across Flanders and as far as northern France, where it is sometimes spelled carbonade with one n. In Brussels it belongs to the trio of dishes a visitor names when asked what they ate, along with mussels and fries and vol-au-vent.

It is also a dish of household economy. Originally it used the cuts of beef that need time, the ones you cannot grill: neck, chuck, cheek. Slow cooking transforms them, and that is precisely why the dish exists.

The Belgian argument, in two camps

Some add a slice of gingerbread spread with mustard at the end of cooking. The gingerbread breaks down, binds the sauce and gives it its sweetness, while the mustard brings the acidity that stops the whole thing becoming cloying. Many Flemish families consider that the only true version.

Others swear it is heresy, and that a carbonnade is made with beer, onions and nothing else. For them, gingerbread is a crutch that hides a badly reduced sauce. The matter is rarely settled at the table, which makes it excellent conversation. Ask a Belgian, and allow some time.

Carbonnade or beef bourguignon?

Visitors ask this often. Both are slow-cooked beef stews, but everything separates them. Bourguignon is made with red wine, bacon, mushrooms and pearl onions: it is tannic and earthy. Carbonnade is made with brown beer, plenty of sliced onions and often a touch of sugar or gingerbread: it is softer, rounder, almost caramelised. One is served with steamed potatoes or pasta, the other with fries. In Belgium, nobody confuses them.

How long it takes

A carbonnade is not made to order. The meat is seared, the onions are cooked down slowly until almost confit, then everything simmers together for two to three hours. Many kitchens make it the day before, because it is better the next day: the sauce has settled and the flavours have come together. That is one reason it disappears from some menus. It needs space, time and planning, which sits badly with fast service.

What our guests say

A Google review left by an English-speaking visitor this summer: "If you're looking for the best carbonnade flamande, this is the place. Absolutely incredible, rich, flavorful, and perfectly cooked." We could not have put it better, and we would not have dared write it ourselves.

If you do not like sweet and savoury

There are three other Belgian classics on the menu, the ones people from Brussels order when they want to eat like at home. Chicken vol-au-vent at 22.90 euros, a white mushroom sauce served with fries. Stoemp with country sausage at 19.90 euros, the vegetable mash that is the Brussels winter dish. Chicory gratin at 22.90 euros, endives rolled in ham and gratinated with cheese. And for those who want to stay with beer cooking, rabbit in cherry beer at 24.50 euros.

What to drink with it

An abbey brown ale, Leffe Brune on tap or Westmalle Double in bottle. The rule is simple: the beer from the dish, or its cousin. If you want something stronger, Chimay Blue stands up to the sauce. If you would rather stay light, the Beer's Garden Blonde, our house blonde on tap, does the job.

When to come

Carbonnade is an autumn and winter dish, but it is on the menu all year. Service runs non-stop from 11am to 11pm, seven days a week, so nothing forces you to arrive at noon sharp or at 8pm. A November afternoon, in the large rooms or near the fountain in the garden, is probably the best moment.

The Beer's Garden is at Place Sainte-Catherine 5/7 in Brussels, two minutes from Sainte-Catherine metro station, lines 1 and 5, and five minutes on foot from the Grand-Place. In the evening and at weekends, it is better to book.
