Instructions
-
Heat the oven to 200°C. Cut the agneau into 4 cm chunks, removing any thick fat. Peel the ail cloves and crush them lightly with the flat of a knife. Strip the romarin leaves from the stems and chop them coarsely.
~15 min
Cutting uniform chunks ensures even cooking, while crushing garlic releases allicin for deeper flavor.
Crushing the ail cloves releases their sweetness into the pan juices without burning, which keeps the traybake mellow rather than sharp.
-
Drain the flageolets thoroughly in a colander, discarding all the liquid. Tip them into the roasting tray with the agneau, ail and romarin. Add 3 tbsp olive oil, 1.5 tsp salt and 0.5 tsp black pepper, then toss everything until evenly coated.
~5 min
Tossing coats every piece evenly, so seasonings and oil are distributed for consistent browning.
-
Pour 200 ml water into the tray and spread the mixture into a single even layer. Cover the tray tightly with aluminum foil and bake for 40 minutes. The lamb should be cooked through and the beans tender.
~40 min
Covering traps steam, cooking lamb through gently before uncovered browning.
Roasting Roast covered first to cook through, then uncovered to brown. Watch for caramelized edges without burning.
-
Remove the foil and bake uncovered for another 35 minutes, stirring once halfway, until the liquid has mostly evaporated and the lamb and beans are browned and caramelized at the edges.
~35 min
Uncovered roasting evaporates liquid and triggers Maillard browning for caramelized edges.

Check the lamb reaches 63°C in the thickest piece. Let the tray rest for 10 minutes before serving so the juices settle into the beans.

Resting allows juices to redistribute, keeping meat moist and flavoring the beans.
Resting meat Rest meat for 5-10 minutes after cooking so juices redistribute. Cutting too early loses moisture.
