Take the Steak out of the fridge and allow to get to room temperature and get your oven to 200°C / 180°C fan / gas mark 6.
With a sharp knife slice the Potatoes into approximately 2cm size slices. Peeling is optional. Add to a baking tray, coat with a drizzle of oil and season with salt and pepper.
Spread out the slices and avoid overlapping where possible. Use a larger baking tray or a second if needed. Place on the top shelf of the oven and roast for around 25 to 30 minutes until they are a golden brown colour.
Slice the Carrot into batons and add to the baking tray. Season with salt and pepper and a little sugar. Add to the middle shelf of the oven.
Slice the Red Onion and place two thirds in a hot pan and start frying for 5 minutes until soft.
Once cooked place in a bowl to one side.
While the Red Onion are frying grab your Steak and season them with salt and pepper. You should also chop the Parsley ready to add at the end.
Once you have removed the Red Onion from the pan add a little oil and place the remaining third of onions. Cook until soft.
Next add some Cracked Black Pepper, Cider Vinegar and Chicken Stock and Water to the pan. Mix them up and allow to simmer for a couple of minutes.
Add the Creme Fraiche and stir it all together. Leave on a low heat.
In a second frying pan heat a little oil and slam the Steak in. Cook for a few minutes on either side and make a medium or well done as you would like.
At this point also add the Red Onion from your bowl onto the potatoes in the oven and allow them to heat up.
Roughly chop the Parsley and add to the sauce and stir through. Add salt and pepper to season as required.
Once ready remove the Potatoes, Carrot and Red Onion from the oven and share onto your plates.
Add the Steak and slice into strips. Finally spoon some of the sauce over your Steak, eat and enjoy!
