Swiss Chard with Horseradish

This vibrant Swiss chard with horseradish is a sophisticated vegan side dish that brings a wonderful depth of flavour to any roast or plant-based main course. By cooking the crunchy stems first before wilting the tender leaves, you achieve a perfect contrast in textures. The addition of spicy horseradish provides a sharp, peppery finish that cuts through the earthy richness of the leafy greens.

As a nutritious, low-calorie accompaniment, this dish is an excellent way to enjoy seasonal greens throughout the year. It pairs particularly well with roasted root vegetables or as a savoury topping for toasted sourdough. Simple to prepare and naturally gluten-free, it offers a fresh and healthy alternative to more traditional buttery greens.

Ingredients for Swiss Chard with Horseradish

  • 1.4kg green Swiss chard (2 to 3 bunches

  • see Cooks' notes)

  • 3 tablespoons olive oil

  • 1 medium onion, halved lengthwise and thinly sliced

  • 3 tablespoons water

  • 1/2 teaspoons salt

  • 1 1/2 tablespoons bottled white horseradish (not drained), or to taste

How to make Swiss Chard with Horseradish

Cut out stems and centre ribs from chard, discarding any tough parts (see Cooks' notes), then chop. Wash leaves well, then cut in half crosswise (leave whole if on the smaller side).

Heat oil in a wide heavy pot (5- to 7-quart capacity) over medium heat until shimmering, then cook onion, stirring occasionally, until it begins to soften, about 5 minutes. Add chard stems and ribs, the water, and 1/2 teaspoons salt, and cook, covered, until just tender, 8 to 10 minutes.

Increase heat to medium-high. Add leaves in handfuls, turning with tongs and adding more as previous batches wilt, until all leaves have been added to pot. Cover with lid, then reduce heat to medium and cook, stirring once or twice, until just tender (do not overcook), 2 to 3 minutes. Remove from heat and stir in horseradish.
