Try: Filet americain
Belgian endive (chicons) wrapped in thick slices of cooked ham, smothered in nutmeg-spiced béchamel and grated Gruyère, baked until the top browns and bubbles. The Brussels Sunday-lunch comfort dish in winter.
Where to eat it: 6 restaurants across 2 cities.
Chicons au gratin became a Belgian household staple in the 1850s after the endive (Witloof) was famously cultivated by accident in the dark Brussels Botanical Garden cellars. The ham-and-béchamel preparation crystallised by the 1920s. Au Vieux Saint Martin and Au Stekerlapatte both run defensible versions through the winter months.
Common allergens: Dairy, Gluten
Tip from the editors. Cut the bitter core out and drain braised endives well; both steps stop the gratin going watery. Double cheese (Gruyère melt, aged Gouda brown) is the trick.
