Dinnertime doesn’t have to be boring, and it certainly won’t be with this recipe. Our chefs have performed culinary magic with their homemade Bernaise butter, made with fried shallots, garlic, parsley and tarragon. The butter, with its herbs, brightens other flavours in this dish and pairs perfectly with the rich flavour of the tender sirloin. Paired with fluffy roasties cooked with oregano and tenderstem which is sweet, delicate and nutty, this dish will make any day feel special!

Due to the conflict in Ukraine, it has been necessary to substitute sunflower oil with rapeseed oil in some products without a label change. The FSA have advised that allergic reactions to rapeseed oil are rare.

Preheat your oven to 200°C. Take the steaks out of the fridge and pop onto a plate to come up to room temperature. Chop the potatoes into 2cm chunks (no need to peel!). Pop the potatoes on a large baking tray in a single layer. Drizzle with oil, and sprinkle on the dried oregano. 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.


Halve, peel and chop the shallot into small pieces. Peel and grate the garlic (or use a garlic press). Finely chop the flat leaf parsley (stalks and all). Pick the tarragon leaves from their stalks and roughly chop (discard the stalks).


Heat a splash of oil in a small saucepan over medium-high heat. Add the shallot and cook, stirring until softened, 3-4 mins. Add the garlic and cook for a minute more then transfer to a bowl. Allow to cool, then add the butter and use a spoon to mash the butter and shallots together. Next, mix in the parsley and tarragon. Bearnaise butter made! Put a saucepan of water onto boil. We will use it for the broccoli later.


When the potatoes have 10 mins left, put a frying pan on high heat with a drizzle of oil. Season the steaks with salt and pepper. When the oil is hot, lay the steaks in the pan and brown for a minute on each side. Once browned, lower the heat slightly and cook for another 1-2 mins on each side. TIP: This will cook the steak to medium rare - if you like yours less rare just cook for 1-2 mins more.


When the steaks are cooked, pop them on to a plate. Spread the butter on top and cover loosely with foil, leave to rest for a couple of mins. When the water is boiling add the tenderstem broccoli along 0.25 tsp of salt and cook until tender, 2-3 mins. Drain in a colander and get ready to serve.


Share the potatoes between your plates and serve the steaks and tenderstem alongside. Drizzle any melted buttery juices over the steak and enjoy!
