Roasted Eggplant and Mozzarella Sandwiches

These italian-inspired sandwiches layer tender roasted eggplant with fresh mozzarella, tomatoes, basil, and a bright balsamic spread. Toasted ciabatta keeps the sandwiches crisp while the warm eggplant gently softens the cheese.
Prep: 20 min · Cook: 30 min · Total: 50 min · Serves: 4
Ingredients
- 2 tbsp balsamic vinegar
- 4 tbsp extra-virgin olive oil (divided)
- 1 tsp kosher salt (divided)
- 1 clove garlic (finely grated)
- 1.25 lb eggplant (cut crosswise into 1/2-inch slices)
- 2 medium tomatoes (sliced)
- 0.25 cup mayonnaise
- 4 rolls ciabatta rolls (split)
- 0.5 cup fresh basil leaves (loosely packed)
- 0.25 tsp red pepper flakes
- 8 oz fresh mozzarella (sliced)
- 0.5 tsp black pepper (freshly ground)
Instructions
- Place an oven rack in the center position and heat the oven to 425°F (220°C) for at least 10 minutes while you prepare the vegetables.
- Line a rimmed half-sheet pan with parchment paper, arrange the 1.25 lb sliced eggplant in a single layer, and pat the slices dry with paper towels so they roast rather than steam.
- Brush both sides of the eggplant with 3 tbsp extra-virgin olive oil, then season evenly with 3/4 tsp kosher salt and 1/2 tsp black pepper.
- Roast the eggplant on the center rack at 425°F (220°C) for 15 minutes, then use tongs to flip each slice and continue roasting for 10-12 minutes until the slices are browned at the edges and tender when pierced with a fork.
- While the eggplant roasts, stir 1/4 cup mayonnaise, 2 tbsp balsamic vinegar, 1 finely grated garlic clove, 1/4 tsp red pepper flakes, and the remaining 1/4 tsp kosher salt together in a small bowl until smooth, about 1 minute.
- Place the 4 split ciabatta rolls cut-side up on a second rimmed baking sheet, brush the cut sides with the remaining 1 tbsp extra-virgin olive oil, and toast them in the 425°F (220°C) oven for 4-5 minutes until lightly golden and crisp at the edges.
- Spread the balsamic mayonnaise evenly over the cut sides of the toasted ciabatta rolls while the bread is still warm.
- Divide the roasted eggplant among the bottom halves of the rolls, using tongs to slightly overlap the slices so each sandwich has an even layer.
- Top each eggplant layer with 2 oz sliced fresh mozzarella, then return the open-faced bottom halves to the 425°F (220°C) oven for 3-4 minutes until the cheese is warm and just beginning to soften but not fully melted.
- Remove the baking sheet from the oven and top each sandwich with sliced tomatoes and 0.5 cup fresh basil leaves divided evenly among the 4 sandwiches.
- Close the sandwiches with the top halves of the rolls, press gently with a spatula for 10 seconds to compact the fillings, and let the sandwiches stand for 2 minutes so the juices settle into the bread.
- Cut each sandwich in half with a serrated knife on a cutting board and serve warm, checking that the eggplant is fully tender and the mozzarella is soft before plating.
