Potato and Autumn Vegetable Hash

This vibrant potato and autumn vegetable hash is a celebratory vegetarian dish that makes the most of the season’s earthy harvest. Featuring a colourful medley of golden baby beets, sweet butternut squash, and fluffy russet potatoes, the vegetables are roasted until caramelised and tender. A homemade herb-infused oil, fragrant with fresh rosemary and oregano, ties the components together, while the addition of wilted beet greens ensures zero-waste cooking and a lovely bitter contrast to the sweet roasted tubers.

Perfect as a substantial weekend brunch or a comforting midweek supper, this recipe is as nutritious as it is visually striking. The combination of textures and the richness of melted butter make it a satisfying main course, though it also works beautifully as a side dish for a Sunday roast. For the best flavour, look for beets with their fresh green tops still attached, as these provide a wonderful spinach-like element to the finished hash.

How to make Potato and Autumn Vegetable Hash

Whisk all ingredients in small bowl. DO AHEAD: Can be made 4 days ahead. Cover and chill. Bring to room temperature and rewhisk before using.

Preheat oven to 177°C. Cut greens and stems off all beets; discard stems. Coarsely chop enough beet greens to measure 4 loosely packed cups. Bring medium saucepan of salted water to boil. Add greens and cook just until wilted, about 1 minute. Drain well. Set aside. Scrub beets; place in 8x8x2-inch glass baking dish. Pour half of herb oil over beets; sprinkle with salt and pepper. Cover baking dish with foil and roast beets until tender when pierced with small sharp knife, about 1 hour. Remove from oven and let beets stand until cool enough to handle. Peel beets; cut into 1/2-inch pieces and reserve. DO AHEAD: Beet greens and beets can be made 1 day ahead. Cover separately and chill.

Increase oven temperature to 191°C. Combine squash, potatoes, and yams in large bowl. Add remaining herb oil and toss to coat. Sprinkle generously with salt and pepper. Spread vegetable mixture evenly on large rimmed baking sheet. Roast until vegetables are tender when pierced with knife and lightly browned around edges, stirring and turning vegetables occasionally, about 50 minutes. DO AHEAD: Can be made 2 hours ahead. Let stand uncovered at room temperature. Rewarm in 177°C oven until heated through, about 15 minutes.

Stir beets and beet greens into roasted vegetables; dot with butter cubes and continue to roast just until beets are heated through, 5 to 10 minutes. Transfer vegetable mixture to large bowl and serve.
