Witloof met Hesp en Kaas
“Flemish endive baked with ham and cheese sauce — Belgian endive (witloof / chicons) blanched, wrapped in slices of cooked ham, draped with béchamel + Gruyère, and baked until the cheese is bubbling and the endive is meltingly soft. The bitter-vegetable centerpiece of Belgian home cooking, eaten with potatoes or bread. Belgium grows half the world's endive (over 60,000 tonnes/year), so naturally it has the canonical dish.”
Where it comes from
Belgian endive ('witloof' in Dutch, 'chicon' in French, literally 'white leaf') was accidentally invented in Brussels in 1830 when the Botanical Garden caretaker stored chicory roots in a dark cellar over winter — the white, tight-leaved shoots that emerged became the modern endive. Belgium remains the world's largest producer and the dish 'chicons-au-gratin' / 'witloof met hesp en kaas' is the national way of preparing them. The blanching step is essential — raw endive is intensely bitter; brief boiling tames it. The ham wrap + bechamel + gruyere = a Flemish 'macaroni au gratin'-style preparation invented in the 20th century for school cafeterias and home kitchens. The dish is everyday food at every Flemish household in late autumn and winter.
On the plate
The first bite is contrast in textures: a thin layer of crackling-cheese crust, then molten béchamel, then a layer of mildly-salty ham, then meltingly soft endive that has shed all its raw bitterness. The endive's character is transformed — what was sharply vegetal becomes deeply caramel-sweet from the long cook with sugar and lemon, slightly silky. The béchamel carries the cheese into the leaves. Cut a piece, lift with a spoon, get the layered effect: cheese + ham + endive + sauce. Comfort food at the deepest level. Eat with mashed potato to soak up the inevitable excess sauce. Belgian Sunday dinner classic.
How it works
Endive's bitterness comes from sesquiterpene lactones (intybin compounds) concentrated in the white core. Cutting out the base cone + blanching in sugared-lemon water hydrolyzes these compounds and dilutes them. The 15-20 minute simmer also breaks down cell walls, allowing the endive to absorb cooking water + sugar + lemon, transforming it from bitter to slightly sweet. The béchamel is a classic 4-tbsp-each butter-and-flour roux, cooked white (not browned), enriched with whole milk to a coating consistency, then enriched with cheese for body and umami. The 200°C bake develops Maillard reactions on the top, creating the dark golden crust.
Variations
Brussels canonical (witloof met hesp en kaas, with mustard); Antwerp variation uses Brugge Vieux cheese for sharper flavor; modern Flemish version omits ham for a vegetarian 'chicons-au-gratin'; Walloon adds nutmeg + black pepper more heavily; modern healthy version uses skim milk + reduced cheese; ham-free vegan version uses béchamel-style sauce with cashews + nutritional yeast; the dish freezes well — Belgian families make double-batches for winter weeknight meals.

Choose 8 fresh Belgian endive heads. Trim off the woody base; remove any outer bruised leaves. Using a small paring knife, cut a cone-shaped hollow at the base 1cm deep (this removes the bitterest part).
- 222 min
Blanch endive: bring a large pot of salted water to a boil. Add the endives + 1 lemon (juice and squeezed halves) + 1 tbsp sugar. Simmer 15-20 min until the endive is tender when pierced with a knife. Drain; squeeze gently to remove excess water (be firm but don't crush).
- 38 min
Make béchamel: in a heavy saucepan melt 4 tbsp butter over medium. Whisk in 4 tbsp all-purpose flour; cook 2 min, whisking constantly. Gradually whisk in 600ml warm whole milk, ensuring no lumps. Cook 4-5 min until the sauce thickens to coat a spoon. Season with 1/2 tsp salt + 1/4 tsp white pepper + pinch nutmeg.
- 42 min
Off heat, whisk in 100g grated Gruyère cheese + 1 tbsp Dijon mustard (optional but traditional). Adjust seasoning.
- 55 min
Preheat oven to 200°C. Grease a 23×30cm baking dish.
- 65 min
Wrap each blanched endive in 1 slice of cooked Belgian ham (Brussels ham or substitute with good-quality ham). Arrange seam-side down in the baking dish.
- 72 min
Pour the béchamel-cheese sauce generously over the endives, ensuring they're fully coated.
- 81 min
Top with another 50g grated Gruyère + 2 tbsp grated Parmesan + a few small pats of butter.
- 928 min
Bake 25-30 min until the top is deep golden-brown and bubbling vigorously. Let rest 5 min before serving (the sauce sets slightly).
- 103 min
Serve in shallow bowls or directly from the baking dish, with boiled potatoes, mashed potatoes, or crusty country bread for soaking up the sauce.
What you'll need
Hand-held wire loop tool for beating eggs, whipping cream, emulsifying dressings, and incorporating air into batters. Balloon whisks (large round head) for whipping cream and meringues; French whisks (narrow tear-drop) for sauces in pots; flat whisks (gravy) for pan sauces. Stainless steel is universal; silicone-coated for non-stick pans.
Round metal pot, 14-26 cm diameter, with vertical walls and a long handle, designed for sauces, soups, oatmeal, rice, boiled vegetables. The vertical walls minimize evaporation (vs. a sauté pan). Sizes: 1 qt for melting butter, 2-3 qt for sauces, 4 qt for soups. Stainless-steel-clad aluminum or copper is best for conduction; cast-iron is too thick for delicate sauces.
