Instructions

  1. Step 1: Preheat oven to 375°F. Toss 1 medium diced eggplant, 1 medium diced zucchini, 1 thinly sliced yellow bell pepper, and 1/2 thinly sliced red onion with 2 tbsp olive oil, 2 tsp chopped thyme, 2 minced garlic cloves, 1/2 tsp salt, and 1/4 tsp black pepper in a large bowl; let sit 15 minutes to release moisture.
  2. Step 2: Spread half the vegetable mixture evenly in a 9x13-inch baking dish. Layer 2 medium thinly sliced tomatoes on top, then sprinkle with 1/4 tsp salt and 1/4 tsp black pepper.
  3. Step 3: Cover the dish with parchment paper, then bake for 30 minutes until vegetables are tender but not mushy.
  4. Step 4: Remove parchment, layer the remaining vegetables over the tomatoes, and drizzle with 1 tbsp olive oil. Bake uncovered for 20-25 minutes until edges are golden and vegetables are caramelized.
  5. Step 5: Let rest 10 minutes before serving; sprinkle with extra thyme if desired.
