Grilled Mustard Broccoli

This grilled mustard broccoli is a vibrant vegetarian side dish that transforms the humble brassica into something truly spectacular. By parblanching the florets before tossing them in a pungent, spiced yoghurt marinade, you ensure a tender interior that contrasts perfectly with the smoky, charred edges. The combination of earthy cumin, bright turmeric, and the signature tang of wholegrain mustard provides a complex depth of flavour that pairs beautifully with grilled meats or as part of a plant-based spread.

Ideal for summer barbecues or as a healthy midweek accompaniment, this dish is naturally high in fibre and packed with nutrients. Using Kashmiri chilli powder offers a mild warmth and a rich red colour without overpowering the other spices. For the best results, ensure the broccoli is patted completely dry after its ice bath, allowing the mustard-infused coating to cling to every crevice for a consistent, savoury finish.

Ingredients for Grilled Mustard Broccoli

  • 2 small heads of broccoli (about 675g)

  • Kosher salt

  • 120ml plain whole-milk Greek yoghurt

  • 1 tablespoon mustard oil or olive oil

  • 1 tablespoon whole grain mustard

  • 5 1/2 teaspoons Kashmiri chilli powder or paprika

  • 1 teaspoon chaat masala

  • 1 teaspoon ground cumin

  • 1 teaspoon ground turmeric

  • Vegetable oil (for grill)

Trim broccoli stems, then cut away from heads. Peel stems and slice lengthwise into 1/4"-thick planks. Break up heads into large florets. Cook florets and stems in a large pot of boiling salted water until bright green and crisp-tender, about 2 minutes. Drain, then transfer to a bowl of ice water to cool. Drain and pat dry with paper towels.

Whisk yoghurt, mustard oil, mustard, chilli powder, chaat masala, cumin, and turmeric in a large bowl. Add broccoli and toss to coat; season with salt.

Prepare a grill for medium-high heat; oil grate. Grill broccoli, turning occasionally, until charred in spots, 5–7 minutes. Transfer to a platter.
