I like to roast more vegetables than I need for one meal. The leftovers are delicious (at any temperature) to make a salad into a meal or just fill out your plate.

The garam masala called for in this recipe is a spice blend that typically has fragrant “sweet” spices like cinnamon, cardamom, and ginger but no chili powder. A tandoori masala is often a mild blend of sweet and savory spices with a hint of chili.

For a simpler dish, skip the yogurt sauce; roast the vegetables then sprinkle with a mixture of the salt and spices while the vegetables are still hot.

Time: 45 minutes 
Serves: 8


  • 1½ lbs. sweet potatoes or yams, peeled and cut into chunks
  • 1 lb. baby purple potatoes, halved
  • 2 Tbs. + 1 Tbs. extra-virgin olive oil
  • 1 bunch large radishes, halved
  • 1 tsp. sweet or smoked paprika
  • ½ tsp. garam masala or tandoori masala
  • ½ cup plain yogurt 
  • 1 clove garlic, finely grated or minced
  • ¼ tsp. + ¼ tsp. kosher salt
  • a few sprigs cilantro or chervil


  1. Preheat the oven to 450°F. On a large baking pan, toss the sweet and purple potatoes with 2 Tbs. oil. Spread in a single layer, flat side down. 
  2. On a medium baking pan, toss the radishes with the remaining 1 Tbs. oil. Spread in a single layer, flat side down.
  3. Roast until the vegetables are tender, 15-30 minutes (the radishes will cook the fastest). Allow the vegetables to cool to warm or room temperature.
  4. While the vegetables are roasting, make the Spicy Yogurt: In a small bowl, whisk together the paprika, masala, yogurt, garlic, and ¼ tsp. salt. Transfer to a serving bowl and set aside until the vegetables are ready. 
  5. Heap the vegetables onto a platter and season with the remaining ¼ tsp. salt. Top with the cilantro. Serve with the Spicy Yogurt.
