One-Skillet Steak and Spring Veg with Spicy Mustard

This vibrant one-pan steak and spring veg dish offers a sophisticated yet simple way to enjoy high-quality beef alongside seasonal greens. By using a single frying pan, the steak’s savoury juices provide a delicious base for a nutritious medley of sweet garden peas and tender asparagus, making it as practical as it is flavourful. The spicy mustard dressing, sharpened with a touch of vinegar and a hint of cayenne, provides a bright, piquant contrast to the rich sear of the meat.

As a diabetes-friendly option, this recipe focuses on lean protein and high-fibre vegetables to create a satisfying, low-carbohydrate meal. It is an ideal choice for a quick midweek dinner or a healthy weekend treat that does not compromise on flair. Serve it at the centre of the table directly from the pan for a rustic feel that highlights the fresh flavours of spring.

Ingredients for One-Skillet Steak and Spring Veg with Spicy Mustard

  • 450g boneless New York strip steak, patted dry

  • Kosher salt, freshly ground pepper

  • 5 garlic cloves, 1 grated, 4 thinly sliced

  • 80ml Dijon mustard

  • 1 tablespoon sherry vinegar or red wine vinegar

  • 1 teaspoon honey

  • 1–2 pinches cayenne pepper

How to make One-Skillet Steak and Spring Veg with Spicy Mustard

Season steak all over with salt and pepper. Whisk grated garlic, mustard, vinegar, honey, cayenne, 80ml oil, and 1 tablespoon water in a medium bowl to combine; season spicy mustard with salt and pepper.

Heat a dry medium skillet, preferably cast iron, over medium-high. Rub steak all over with 1 tablespoon oil and cook, turning every 2 minutes or so and making sure to get colour on the fat cap, until medium-rare (an instant-read thermometer inserted into the centre will register 49°C), about 10 minutes. Transfer steak to a plate to rest. Pour off oil from skillet, leaving crispy bits behind.

Heat remaining 2 tablespoons oil in same skillet over low. Add sliced garlic and all but about 2 tablespoons spring onions (save those for serving) and cook, stirring often, until translucent and softened, about 3 minutes. Add peas and a splash of water and cook, stirring and mashing to break up slightly, until peas are tender, about 5 minutes. Add asparagus; season with salt and pepper. Cook, stirring often, until asparagus is just tender, about 5 minutes. Remove from heat.

Slice steak and shingle over vegetables in skillet. Drizzle some mustard sauce over steak and top with reserved spring onions. Serve with remaining mustard sauce alongside.
