Aubergine, Tomato, and Pesto Stack

These elegant aubergine, tomato and pesto stacks are a vibrant celebration of Mediterranean flavours. By roasting thick rounds of aubergine until golden and tender, you create a sturdy, savoury base for layers of juicy heirloom tomatoes and creamy fresh mozzarella. The dish is brought to life with a rich, homemade walnut pesto that offers a nutty depth and aromatic finish, perfect for a light summer lunch or a sophisticated vegetarian starter.

This simple yet impressive vegetarian recipe is packed with fresh ingredients and healthy fats from the extra-virgin olive oil and walnuts. The contrast between the warm roasted aubergine and the fresh, cool tomato and cheese makes it a delightful choice for alfresco dining. Serve these stacks as they are, or alongside a crisp green salad and some crusty sourdough bread to soak up the balsamic dressing.

Ingredients for Aubergine, Tomato, and Pesto Stack

  • 50g plus 2 tablespoons chopped walnuts, divided

  • 2 cups fresh basil leaves, plus more for garnish

  • 3 medium garlic cloves

  • 120ml plus 1 1/2 tablespoons extra-virgin olive oil, divided

  • 120ml grated Parmesan

  • 1 large aubergine, cut into 8 1/2-inch rounds

  • 1 teaspoon sea salt

  • 2 large heirloom tomatoes, cut into 4 slices each

  • 4 slices (110g) fresh mozzarella

  • 1 tablespoon balsamic vinegar

In a food processor, pulse 1/2 cup walnuts until finely chopped. Add 2 cups basil and garlic, and pulse while slowly adding 120ml oil, scraping down sides as needed until smooth, about 1 minute. Add Parmesan; season with salt and black pepper; process until pesto is well combined. Heat oven to 204°C. Brush aubergine slices with remaining 1 1/2 tablespoons oil and sprinkle with sea salt; roast on a baking sheet, turning once, until tender and golden, 20 minutes. Top each with 1 tablespoon pesto. Alternately layer 2 aubergine slices, 2 tomato slices and 1 slice mozzarella. (Refrigerate any remaining pesto for another use.) Divide balsamic vinegar, remaining 2 tablespoons walnuts and basil leaves among stacks.
