This steak and celeriac dish is quick and easy, yet delivers big flavours meaning that you can cook something imaginative midweek. Earthy celeriac is a great alternative to chips and works perfectly with the rich red wine sauce.
Simmer the celeriac in water for about 15 minutes or until it is tender. Drain and mash with milk and lots of seasoning.
Put a little oil in a hot frying pan and add the steaks, add the onion around the edges and cook for 2 minutes. Turn the steaks over and stir the onions around. After 2 minutes, add the red wine and brown sugar and bubble everything together to make a sauce. Season well and serve with the mash.
