Instructions

  1. Step 1: Preheat oven to 400°F. In a large mixing bowl, combine 1 medium diced eggplant, 2 medium sliced zucchini, 1 medium sliced yellow squash, 1 large diced red bell pepper, 1 large diced yellow bell pepper, and 4 chopped tomatoes. Add 6 minced garlic cloves and 1/4 cup olive oil, tossing gently to coat all vegetables evenly.
  2. Step 2: Spread the vegetable mixture on a large baking sheet in a single layer. Sprinkle 1 tbsp chopped fresh thyme, 1 tsp salt, and 1/2 tsp black pepper evenly over the top. Roast uncovered for 35 minutes, stirring halfway through, until vegetables are tender and edges start to caramelize.
  3. Step 3: Remove from oven and stir in 1/4 cup chopped fresh basil while the ratatouille is still warm. Let it rest for 5 minutes before serving to allow flavors to meld.
