Easy, essential, tasty. Of course, you need to like meat in principle; otherwise, stick to the roast potatoes which are great anyway, even on their own. For the meat, I chose a sirloin steak medallion, very close to fillet and roughly £5 less per kilo. The potatoes are Charlotte ones, because I love their sweet nuttiness and their golden colour. (Also their name, to be honest). This recipe for potatoes is fantastic: it is easily prepared and it gives you a chance to serve lovely roast potatoes with an alluring look. Try it!
Sirloin steak medallion with roast potatoes (serves 4)
4 sirloin steak medallions (about 180 g each)
2 kg potatoes
1 or 2 garlic cloves
3 tbsp olive oil
40 g butter
a few fresh thyme sprigs
Start with peeling, washing, and drying the potatoes with a cloth. Melt about 20 g of butter and add it to two tbsp of olive oil. Use part of this to line your baking tin–you can line it with foil, but still use the melted butter on top of the foil. Slice the potatoes with a mandoline, about 1.5 mm thick.
Place the potato slices in rows, do not worry if they look a bit tight, it is perfectly fine. If you place them too loose, they will dry out and burn. Brush the potatoes with the remaining melted butter and olive oil mix. Finely chop the shallot and place between the potatoes rows. Place in hot oven for 1 hour at 200°C/180°C fan/gas mark 6.
While your potatoes cook, take the meat out of the fridge and let it rest on the counter without covering it–half an hour is usually fine, depending on how thick is your meat cut and if you are using a piece with bone, e.g. a côte de boeuf. I used here sirloin steak medallions, which are a rather lean part of the sirloin, at the top of the fillet.
Once the potatoes have cooked for an hour, take them out of the oven, add salt and the thyme sprigs, and put back in the oven for another 15-20 minutes till perfectly golden cooked and slightly brown on some of the top rims.
Once the potatoes are back in the oven, season the meat, put 1 tbsp of olive oil in a hot pan, add the garlic, and brown the meat. Add the remaining butter (about 20 g) and spoon it over the meat as it melts and foams, and cook both sides. My preference is medium-rare, usually ready in 15-16 minutes. Leave for about 20 minutes for medium, and 25 minutes for medium-well. These cooking times may vary according to the steak thickness and cut.
Take off the fire and let the meat rest for a few minutes, while you take the potatoes out of the baking tin. Serve one row of potatoes–about two or three–per beef steak. Accompany with a bottle of Barbaresco, you won’t be disappointed.
