This dish affords the chance to improvise with what you find at your local market. Try purple potatoes in place of fingerlings, Maui or Walla Walla onions instead of Vidalias, or sliced beefsteak heirloom tomatoes for the grape or cherry tomatoes.

  • 1 medium yellow bell pepper
  • 1 medium red bell pepper
  • 2 tbsp olive oil divided
  • 450 g fingerling potatoes peeled and cut into slices
  • 1/4 cup fresh basil chopped
  • 1 tsp sea salt
  • 1/4 tsp freshly ground black pepper
  • 3 garlic cloves thinly sliced
  • 4 cups sweet onion thinly vertically sliced
  • 2 cups zucchini sliced
  • 1 cup yellow squash sliced
  • 1 cup grape or cherry tomatoes halved
  • 3 tbsp water
  • flat-leaf parsley optional


  • Preheat broiler.
  • Cut bell peppers in half lengthwise, and discard seeds and membranes. Place pepper halves, skin sides up, on a foil-lined baking sheet; flatten with hand. Broil 8 minutes or until blackened. Place in a zip-top plastic bag; seal. Let peppers stand 5 minutes. Peel and cut into strips.
  • Heat 1 tablespoon oil in a deep 10-inch cast-iron skillet over medium heat. Add potatoes, tossing to coat. Spread potatoes in a single layer in pan. Sprinkle with 1 tablespoon basil, 1/4 teaspoon salt, 1/8 teaspoon black pepper, and 1/3 of garlic. Arrange onion, zucchini, and squash over seasonings. Sprinkle with 1 tablespoon basil, 1/4 teaspoon salt, remaining 1/8 teaspoon black pepper, and 1/3 of garlic. Top with roasted bell peppers, remaining 2 tablespoons basil, remaining 1/3 of garlic, and tomatoes. Drizzle remaining 1 tablespoon oil and water over top; sprinkle with remaining 1/2 teaspoon salt. Cover, reduce heat to low, and cook 25 minutes or until vegetables are tender. Uncover; increase heat to high, and cook 3 minutes or until liquid almost evaporates. Garnish with parsley, if desired.
