Ingredients

• 2 medium zucchini, sliced lengthwise into 1/4-inch (6 mm) strips
• 1 large red bell pepper, quartered and seeded
• 1 medium eggplant, sliced lengthwise into 1/4-inch (6 mm) strips
• 1 small red onion, sliced into 1/4-inch (6 mm) rings
• 4 tablespoons (60 ml) extra-virgin olive oil
• 1 teaspoon (5 g) kosher salt
• 1/2 teaspoon (2 g) freshly ground black pepper
• 4 slices ciabatta bread or Italian sandwich bread, each 1/2 inch (12 mm) thick
• 8 leaves fresh basil
• 4 ounces (115 g) fresh mozzarella, sliced
• 2 tablespoons (30 g) roasted red pepper hummus or pesto (optional)

Instructions

1. Preheat a grill pan or outdoor grill to medium-high heat (approximately 400°F/200°C). Brush zucchini, eggplant, bell pepper, and onion slices with 3 tablespoons of olive oil on both sides.

2. Season all vegetables generously with salt and pepper. Grill vegetables for 3–4 minutes per side until tender with distinct grill marks and light char. Work in batches to avoid overcrowding.

3. Transfer grilled vegetables to a clean cutting board. Allow them to cool slightly for 2 minutes, then cut into bite-sized pieces approximately 2 inches (5 cm) long.

4. Brush one side of each ciabatta slice lightly with the remaining 1 tablespoon of olive oil. Place two slices oil-side-down on the grill pan over medium heat.

5. Toast bread for 2 minutes until the bottoms are golden and crispy. Remove from heat and place toasted-side-up on a work surface.

6. On the untoasted side of the first bread slice, layer 2 basil leaves, half of the grilled vegetables, and half of the mozzarella slices. Spread optional hummus or pesto on the second bread slice's untoasted side if using.

7. Press the two bread slices together with untoasted sides inward, creating a sandwich. Repeat with remaining bread, basil, vegetables, and mozzarella to make the second panini.

8. Return both panini to the grill pan over medium heat. Grill for 2–3 minutes per side, pressing gently with a spatula, until bread is golden-brown and cheese begins to soften.

9. Transfer panini to a cutting board and rest for 1 minute. Cut diagonally and serve immediately while warm.

Substitutions

• Replace fresh mozzarella with 2 ounces (60 g) of provolone or fontina cheese for stronger flavor
• Substitute eggplant with 1 large portobello mushroom cap, sliced and grilled the same way
• Use vegan cheese instead of mozzarella for a dairy-free version
• Swap red bell pepper with grilled artichoke hearts or sun-dried tomatoes for variation

Tips

• Slice vegetables evenly so they cook at the same rate and achieve uniform grill marks
• Dry vegetables with paper towels before oiling to reduce excess moisture and improve browning
• Use high-quality ciabatta bread with a crispy crust and airy crumb for the best panini texture
• Apply gentle, steady pressure with the spatula while grilling the assembled panini to ensure even melting and crispy bread

The panini tradition in Italy reflects regional resourcefulness, transforming simple grilled vegetables and cheese into a satisfying meal. Originally born from the need to use seasonal produce efficiently, grilled vegetable panini became a staple in Italian delis and cafés, where quality ingredients and proper pressing technique distinguish an authentic panini from ordinary sandwiches.
