Preheat your oven to 200°C. Chop the potatoes into chips 1cm wide (no need to peel!). Pick the rosemary leaves from their stalks and roughly chop (discard the stalks). Pop the fries on a large baking tray in a single layer. Drizzle with oil and sprinkle on the rosemary. Season with salt and pepper. Toss to coat in the oil, then roast on the top shelf of your oven until golden, 25-30 mins. Turn halfway through cooking.

Meanwhile, halve, peel and thinly slice the red onion. We will add them to the fries later. Trim and discard the tough woody 1cm from the asparagus. Halve the asparagus widthways. Lay 2 bacon rashers side by side on your chopping board. Wrap the rashers around a steak. Repeat for the remaining steak(s). Keep to one side. IMPORTANT: Wash your hands after handling raw meat.

Put the creme fraiche (see ingredients for amount) into a small saucepan and warm over a low heat. Season with pepper and then stir in the blue cheese. Keep stirring until the cheese has melted and the sauce is nice and smooth. Remove from the heat, we will reheat it later. Scatter the red onion slices over your fries when you turn them and return to the oven for the remaining cooking time.

Heat a splash of oil in a frying pan over medium high heat. When hot, add the bacon wrapped steaks to the pan. Fry until the browned, 1- 2 mins on each side. Lower the heat to medium and cook the steaks for another 2-3 mins on each side if you want them cooked to medium-rare. Add 1-2 mins extra on each side if you like your steak medium or well done.

When the steaks are ready, transfer to a plate and wrap loosely in foil to keep warm. Return the frying pan to a medium heat, add a splash of oil if necessary and when hot add the asparagus. Stir fry until just tender, 2-3 mins. Season with salt and pepper and get ready to serve.

Reheat the blue cheese sauce until hot, but don't allow to boil. Share the fries between your plates and place the asparagus alongside. Slice your fillet steak diagonally into 2 pieces. Spoon the sauce onto your plate and sit the steak pieces in the sauce. Bon appetit!
