Cooking Instructions
Instructions for 2 people (double for 4)
1 Rump Steak, Creamy Mustard Sauce & Parmentier Potatoes

Preheat the oven to 200°C/ 180°C (fan)/ 395°F/ Gas 6

Boil a kettle, then cut the potatoes (skins on) into small bite-sized cubes

Peel and finely chop (or grate) the garlic

Strip the rosemary leaves from the stalks and chop finely

Combine the chopped rosemary with half the chopped garlic in a bowl and set aside for later

2 Rump Steak, Creamy Mustard Sauce & Parmentier Potatoes

Add the cubed potatoes to a baking tray with a generous drizzle of vegetable oil and a pinch of salt and pepper and give everything a good mix up

Put the tray in the oven and cook for an initial 20 min or until starting to crisp

3 Rump Steak, Creamy Mustard Sauce & Parmentier Potatoes

Add the green beans to a pot of boiling water over a high heat and cook for 3-4 min or until cooked with a slight bite

Once done, drain, rinse under cold water and set aside for later

Tip: Rinsing the beans with cold water will keep the bright green colour

Meanwhile, pat the rump steaks dry with kitchen paper, rub them with vegetable oil and season both sides with salt

4 Rump Steak, Creamy Mustard Sauce & Parmentier Potatoes

Heat a large, wide-based pan (preferably non-stick) over a high heat and once very hot, add the steaks

For medium-rare, cook for 2-3 min on each side

For medium, cook for 3-4 min on each side

For medium-well, cook for 4-5 min on each side

Tip: Don’t move the steaks around too much in the pan – this will stop them from browning

Once done, transfer the steaks to a plate to rest

5 Rump Steak, Creamy Mustard Sauce & Parmentier Potatoes

Once the potatoes are starting to crisp, sprinkle over the garlic & rosemary and cook for 5-7 min further or until the potatoes are golden and crispy – these are your parmentier potatoes

6 Rump Steak, Creamy Mustard Sauce & Parmentier Potatoes

Return the pan to a low heat and add 100ml [150ml] cold water and scrape up any bits stuck to your pan with a wooden spoon (this will help to cool the pan quicker)

Stir in the soy sauce, clotted cream, soft cheese and wholegrain mustard and cook for 2-3 min or until the sauce has thickened to a double cream-like consistency (add a splash of water if it's looking a little thick) – this is your mustard sauce

7 Rump Steak, Creamy Mustard Sauce & Parmentier Potatoes

Return the pot to a medium heat with a knob of butter

Once melted, add the remaining chopped garlic and cook for 1 min or until fragrant

Add the cooked green beans with a pinch of salt and cook for 1 min further – these are your garlic green beans
