Ingredients

  • 2 medium eggplants cut into 3/4" cubes
  • 3 medium zucchini and/or squash cut into 3/4" cubes
  • 4 medium heirloom tomatoes cut into 3/4" cubes
  • 2 colored bell peppers purple, yellow, red or orange
  • 2 small onions red and yellow, cut into 3/4" cubes or larger
  • 4 cloves garlic smashed and peeled and root tip removed
  • 4 sprigs fresh thyme
  • 2 springs fresh rosemary removed from the stem and chopped
  • 1/4 cup olive oil
  • 1 teaspoon kosher or sea salt
  • fresh basil when plating

Instructions

  1. Preheat the oven to 425 degrees and line two baking sheets with parchment paper.

  2. Place all of the cut vegetables, garlic and herbs in a big bowl. Drizzle with 1/4 cup olive oil and toss well. Add the salt and toss again to combine.

  3. Cover baking sheets loosely with foil and bake for 45 minutes.

  4. Remove the foil, lower the temperature to 400 and let the vegetables cook 30 more minutes. Check on the vegetables during this 30 minutes, as you might find the vegetables are golden and cooked to your liking sooner.

  5. Remove from the oven and remove the thyme sprigs. Though you can eat it now, I prefer to let the ratatouille cool thoroughly and then refrigerate overnight, as the flavors will meld and get even better in the days to come.

  6. When ready to serve, you can heat it up in a skillet or serve at room temperature and top with fresh basil. Serve over polenta, pasta or rice or serve with crostini as a veggie-froward appetizer that everyone will love. Refrigerate any leftovers.
