The Story
This gratin is basically France's onion soup and Britain's boiled cabbage finally sorting out their centuries-old rivalry over a shared casserole dish—French cooks in 1960s Lyon were already caramelizing onions into oblivion while the Brits were busy destroying cabbage with nothing but water and resentment, and somebody, somewhere, mercifully decided to combine the two with Gruyère as the peace treaty.
Regional Twist
Up in Alsace, they'd swap the vegetable stock for a splash of Riesling and pack in extra Gruyère, because the Alsatians consider any cabbage dish lacking proper wine and cheese to be a punishable offense against regional pride.

👨🍳 Instructions
- 1
Thinly slice the onions, season with salt, and sauté in olive oil until soft. Set aside.
- 2
Cut the cabbage into wedges, season with salt, and sear on both sides in plenty of olive oil until golden. Use a second pan to press the wedges for the best results.
- 3
In a jug, combine the cream and stock.
- 4
Layer the cabbage and onions in a heatproof casserole dish or cast iron skillet. Pour over the cream mixture, add cheeses, thyme sprigs, and season with salt and pepper.
- 5
Roast at 200°C for 20-30 minutes, until bubbly and golden on top.
💡 Pro Tips
- ✓Caramelize onions for 35-40 minutes over medium heat before adding to the gratin; Maillard reactions at 300-330°F develop sulfur compounds that deepen umami and prevent the dish from tasting one-dimensionally creamy.timing35-40 minutes, 300-330°F
- ✓Press cabbage wedges with a second pan during searing to achieve 85-90% surface contact with oil, creating a flavorful crust through caramelization while the interior steams.technique85-90% surface contact
- ✓Use a 3:2 cream-to-stock ratio (200ml cream to 133ml stock instead of 150ml) because the gratin's 20-30 minute roast will reduce liquid by 25-30%, and this ratio prevents a watery finished dish while maintaining sauce coating consistency.ingredient3:2 ratio, 25-30% reduction
- ✓Mix 70g Gruyère with 30g blue cheese (rather than 50g each) to avoid an overly sharp flavor; the 60% Gruyère provides emulsifying casein proteins that create a stable, creamy sauce while the 40% blue cheese adds pungency without dominance.ingredient70g:30g ratio (60:40%)
- ✓Roast at 200°C for exactly 25 minutes covered with foil, then remove foil and broil at 450°F for 2-3 minutes; this method prevents curdling of the cream sauce (which breaks above 180°C sustained heat) while the final broil creates a golden, crispy cheese crust.timing25 minutes at 200°C covered, then 2-3 minutes broil at 450°F
