Ingredients Equipment Method

Ingredients
  

  • 1 medium eggplant sliced into 1/4-inch rounds
  • 2 medium zucchini sliced into 1/4-inch rounds
  • 2 large bell peppers preferably different colors, sliced into strips
  • 4 medium tomatoes ripe, sliced into rounds
  • 3 cloves garlic minced
  • 2 tbsp olive oil for tossing vegetables
  • 1 tsp dried thyme or herbes de Provence or fresh herbs if preferred
  • to taste salt and pepper for seasoning

Equipment

  • Large rimmed baking sheet
  • Sharp knife and cutting board
  • spatula or tongs
  • Oven

Method
 

  1. Preheat your oven to 200°C (400°F).
  2. Slice the eggplant, zucchini, bell peppers, and tomatoes into roughly 1/4-inch thick rounds or strips, arranging them so they’re uniform for even roasting.
  3. In a large bowl, toss all the sliced vegetables with olive oil, minced garlic, dried thyme, salt, and pepper until evenly coated and fragrant.
  4. Spread the coated vegetables in a single, even layer on a large rimmed baking sheet, making sure not to overcrowd the pan for proper caramelization.
  5. Place the sheet in the oven and roast for 15 minutes, until the vegetables start to soften and develop slight char marks.
  6. Using tongs or a spatula, gently stir or flip the vegetables to promote even roasting and prevent sticking.
  7. Return the sheet to the oven and roast for another 10-15 minutes, until the edges are golden brown and vegetables are tender, fragrant, and slightly caramelized.
  8. Remove the pan from the oven, and check that the vegetables are soft and fragrant, with crispy edges for added texture.
  9. Taste and adjust seasoning with additional salt, pepper, or fresh herbs if desired. Serve hot directly from the pan or transfer to a serving dish.
