Green Bean Potato Sweet Potato Traybake

Roasted green beans, potatoes and sweet potatoes with garlic, topped with a tangy yogurt-mustard dressing for a simple satisfying meal.

Ingredients

For the Traybake

  • 300g green beans, trimmed
  • 250g regular potatoes, cut into 2cm cubes
  • 250g sweet potatoes, cut into 2cm cubes
  • 4 garlic cloves, unpeeled
  • 2 tbsp olive oil
  • Salt and pepper to taste
  • 1 tsp dried thyme

For the Yogurt-Mustard Dressing

  • 150g low-fat Greek yogurt
  • 2 tsp Dijon mustard
  • 1 tsp whole grain mustard
  • 1 tbsp olive oil
  • Salt and pepper to taste

Instructions

  1. Preheat oven to 200°C (400°F).
  2. Place potatoes and sweet potatoes on a large baking tray, drizzle with 1 tbsp olive oil, season with salt, pepper and thyme, and roast for 15 minutes.
  3. Add green beans and garlic cloves to the tray, drizzle with remaining olive oil, toss everything together, and roast for another 20 minutes until vegetables are tender and slightly caramelized.
  4. Meanwhile, mix Greek yogurt, both mustards, olive oil, salt and pepper in a small bowl until smooth.
  5. Remove garlic cloves from the tray, squeeze the soft garlic from the skins, and stir into the yogurt dressing.
  6. Serve vegetables warm with the yogurt-mustard dressing drizzled over or on the side.

Notes

You can roast the garlic cloves with their skins on - they become sweet and soft, perfect for adding to the dressing. If you prefer a lighter dressing, thin it with a splash of water or plant-based milk.

Variations

  • Add 200g halloumi cubes in the last 15 minutes of roasting for extra protein
  • Replace green beans with broccoli florets
  • Add chickpeas for additional protein and fiber
  • Use curry powder instead of thyme for an Indian-inspired version
  • Add fresh dill or parsley to the yogurt dressing
