Denver Steak with Romesco & Sage Potatoes

The star of the show is Denver steak from grass-fed British beef - therefore, we're keeping everything else simple. Crispy roast baby potatoes. Smokey and tomatoey romesco sauce. Wilted cavolo nero, lightly seasoned. It's the best of British produce.

Cooking Instructions

The protein cooking time listed in this recipe has been updated.

As of December 2025, we’ve revised cooking times for all our proteins to reflect improved food safety guidance.

Check out the latest recommended times in our Cooking Guidelines.

  1. Preheat the oven to 240C / fan 220C / gas mark 9. Halve the potatoes and place onto a lined baking tray. Drizzle with 1 tbsp oil and season with sea salt and black pepper. Roast for 25-30 mins, until golden.
  2. Halve the tomatoes, drizzle with 1/2 tbsp oil and season with a pinch of sea salt. Add them to the tray with the potatoes for the final 10-12 mins of cooking.
  3. Meanwhile, pick the sage from their stalks and finely chop. Strip the cavolo nero leaves from the stalk and cut into bite-sized pieces. Put the romesco sauce into a small bowl and add 1 tbsp olive oil and 1 tbsp cold water. Mix well to combine. Season with a pinch of sea salt and set aside.
  4. Heat a frying pan with 1/2 tbsp oil on medium-high heat. Season the steaks with sea salt and black pepper and cook (as a guide: cook for 2-3 mins on each side for medium, or 3-4 mins for medium-well). Leave to rest then slice against the grain.
  5. Return the empty pan to a medium-high heat. Add the cavolo nero and a splash of water. Season with a pinch of salt and cook for 3-4 mins, until soft.
  6. Just before serving, toss the potatoes with the sage, cavolo nero, tomatoes and half the romesco sauce. Lay the steak on top, then spoon over the remaining romesco sauce.
