Prep the Potatoes

Preheat your oven to 240°C/220°C fan/gas mark 7. Fill and boil your kettle.

Remove the steaks from the fridge to come up to room temperature before cooking.

Pour enough oil into a deep baking tray to cover the bottom and pop into the oven.

Peel the potatoes, then chop into 3cm chunks.

Start the Roasties

Pour the boiled water into a large saucepan on high heat with 1/2 tsp salt. Boil the potatoes for
5-6 mins or until the edges are soft.

Meanwhile, halve the baby plum tomatoes. Peel and grate the garlic (or use a garlic press).

Once the potatoes are ready, drain in a colander. Sprinkle on the flour (see pantry for amount), dried rosemary and season with salt. Shake to fluff up the potatoes.

Dress the Tomatoes

Take the hot baking tray out of your oven and carefully add the potatoes, turning in the oil. Roast on the top shelf until golden, 30-35 mins.

Meanwhile, in a small bowl, mix together the sugar and olive oil for the dressing (see pantry for both amounts) with the red wine vinegar and half the wholegrain mustard. Season with salt and pepper. 

Add the baby plum tomatoes to the dressing. Toss to coat and set aside.

Fry your Steaks

When the ptoatoes have 15 mins remaining, heat a drizzle of oil in a large frying pan on high heat. Season the steaks with salt and pepper. TIP: Rump steaks naturally vary in shape, so adjust the following timings depending on how you like yours cooked.

Once very hot, lay the steaks into the pan and fry until browned and medium-rare, about 5 mins. Turn halfway through. TIP: Cook each side for 1 min more if you like it more well done.

Once cooked, transfer to a board, cover with foil and allow to rest for a couple of mins. IMPORTANT: Wash your hands and equipment after handling raw steaks. They're safe to eat when browned on the outside.

Mustard Sauce Time

Return the (now empty) pan to medium-high heat, adding a drizzle more oil if needed (no need to clean).

Once hot, add the garlic and fry for 1 min, then stir in the creme fraiche, chicken stock paste, water for the sauce (see pantry for amount) and the remaining wholegrain mustard.

Bring to the boil, then lower the heat and simmer until thickened, 3-5 mins. Taste and season with salt and pepper if needed.

When the potatoes have 5 mins left, remove the tray from the oven and sprinkle over the Parmigiano Reggiano. Return to the oven and roast for the remaining time.

Finish and Serve

Just before you're ready to serve, toss the rocket through the tomatoes.

Slice your steaks widthways and serve with the parmesan roasties and salad alongisde.

Spoon the creamy mustard sauce over your steaks to finish.
