Step 1

This recipe works great as a stand-alone dish, but also as a component in Jamie’s Steak night from Together – see the full collection of menus here.

Step 3

ON THE DAY Preheat the oven to 200°C/400°F/gas

Step 4

Peel the onions, cut into 1cm-thick rounds and place in a large roasting tray. Dot over the butter and drizzle with 1 tablespoon of olive oil, then peel, slice and scatter in the garlic, as well as the sprigs of thyme. Add a pinch of sea salt and black pepper, toss together, then arrange in a single layer. Roast for 30 minutes on the middle shelf, giving the tray a jiggle halfway through. Remove, drizzle with the honey and red wine vinegar, mix well and shake flat. Cover with tin foil until needed.

Step 6

TO SERVE When the steak is resting, return the onions to the oven, covered, for 15 minutes, or until sticky and sweet. Before serving, season to perfection, tasting and tweaking.
