Ingredients
- 1 medium eggplant
- 2 medium zucchini
- 1 red bell pepper
- 1 medium onion
- 4 cloves garlic
- 4 tbsp olive oil
- 1 tsp dried thyme
- 1/2 tsp salt
Instructions
- Step 1: Preheat oven to 400°F (200°C). Cut 1 medium eggplant and 2 medium zucchini into 1/2-inch thick slices. Slice 1 red bell pepper into strips and dice 1 medium onion into 1/4-inch pieces.
- Step 2: In a large bowl, toss eggplant, zucchini, bell pepper, onion, and 4 minced garlic cloves with 4 tbsp olive oil, 1 tsp dried thyme, and 1/2 tsp salt until evenly coated.
- Step 3: Arrange vegetables in a single layer on a parchment-lined baking sheet, ensuring they don't overlap. Roast for 25-30 minutes, flipping halfway through, until vegetables are tender and golden brown at the edges.
- Step 4: Let rest for 10 minutes before serving. The vegetables should be soft but hold their shape, with a slightly caramelized exterior and sweet, earthy flavor.
