Mustard-Roasted Potatoes

These mustard-roasted potatoes offer a vibrant twist on a classic side dish, combining the punchy heat of wholegrain Dijon mustard with aromatic oregano and bright lemon juice. By using a mix of red and white-skinned potatoes, you create an appealing contrast in texture and colour that elevates any meal. The mustard coating creates a beautifully crisp, savoury crust while the garlic and butter ensure the centres remain rich and fluffy.

This vegetarian dish is an excellent accompaniment to a traditional Sunday roast, grilled fish, or as part of a festive spread. Because they can be prepared in advance and quickly crisped up before serving, they are a practical choice for busy hosts looking to add more flavour to their potato repertoire without extra stress.

Ingredients for Mustard-Roasted Potatoes

  • Nonstick vegetable oil spray

  • 120ml whole grain Dijon mustard

  • 2 tablespoons extra-virgin olive oil

  • 2 tablespoons (1/4 stick) butter, melted

  • 2 tablespoons fresh lemon juice

  • 3 garlic cloves, minced

How to make Mustard-Roasted Potatoes

Position 1 rack in top third of oven and 1 rack in bottom third of oven and preheat to 218°C. Spray 2 large rimmed baking sheets with nonstick spray. Whisk mustard, olive oil, butter, lemon juice, garlic, oregano, lemon peel, and salt in large bowl to blend. Add potatoes; sprinkle generously with freshly ground black pepper and toss to coat. Divide potatoes between prepared baking sheets, leaving any excess mustard mixture behind in bowl. Spread potatoes in single layer. Roast potatoes 20 minutes. Reverse baking sheets and roast until potatoes are crusty outside and tender inside, turning occasionally, about 25 minutes longer. DO AHEAD: Can be made 2 hours ahead. Let stand on baking sheets at room temperature. Rewarm potatoes in 218°C oven 10 minutes.

Transfer potatoes to serving bowl.
