21-Day Aged Sirloin Steak & Mustard Smashed Potatoes
with Spinach & Sundried Tomato Butter Sauce
Nothing quite beats a sirloin steak pan-fried to perfection and paired with sides that accentuate its delicious rich flavour, and that’s how we know we have a winner with this recipe. Succulent steak works great with the tangy taste of mustard, which adds extra texture and bite to this recipe when stirred through the smashed potato side. To get the perfect steak, slice against the grain when cutting. Check the direction of the muscle fibres and cut against these for a steak that is tender and easy to chew.

Remove the steaks and butter from the fridge to bring them up to room temperature. Submerge the sun-dried tomatoes in a bowl of hot water and set aside. Fill and boil your kettle, then fill a large saucepan of water with boiled water. Return to the boil with a pinch of salt for the potatoes.
Chop the new potatoes into 2cm chunks (no need to peel). Add the potatoes to the saucepan of boiling water and cook until you can easily slip a knife through, 12-15 mins. Drain in a colander and set aside when cooked.
Meanwhile, put the butter in a small bowl and mash with a fork until soft. Remove the sun-dried tomatoes from the water, pat dry and finely chop. Finely chop the parsley (stalks and all). Stir the sun-dried tomatoes and half the parsley through the butter. Set aside.
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.Transfer to a plate, top with the tomato butter and leave to rest loosely covered with foil.
While the steak rests, return the (now empty) frying pan to high heat with a drizzle of oil. When hot, tip in the drained potatoes and lower the heat to medium. Leave to cook, turning occasionally, until browned at the edges, 3-4 mins. Use a fork to roughly smash a few of the potatoes - this will give you lots of delicious crispy edges!
Stir the wholegrain mustard through the potatoes followed by the spinach. Lower the heat and leave for a minute to wilt the spinach while you slice the steak. Slice the steak (or serve whole if you prefer) and serve with the mustard smashed potatoes alongside. Spoon over the sun-dried tomato butter sauce (it should have melted while the steaks rest!) and finish with a sprinkling of remaining parsley. Enjoy!
