Serves 6 (a 30 cm / 12-inch round dish or a 22x32 cm / 9x13-inch rectangular dish)
- 1 kg (2.2 lb) eggplant (aubergine), cut into thin rounds (about 3 large)
- 350 g (12 oz) mozzarella, diced, or 300 g (3 cups) shredded mozzarella
- 100 g (1 cup) grated Parmesan
For the tomato sauce
- 800 g (28 oz) crushed tomatoes
- 1 small can tomato paste (135 g / 4.75 oz)
- 1 glass (200 ml / ¾ cup + 1 Tbsp) water
- 1 small onion, thinly sliced
- 2 cloves garlic, crushed, green germ removed
- 1 pinch dried chili flakes (optional)
- a few basil leaves (chopped, plus whole leaves for garnish)
- 2 Tbsp olive oil
- Salt, pepper
Preparing the eggplant
- Wash the eggplant and cut it into thin rounds (between 0.7 and 1 cm / about ⅓ inch thick). Sprinkle with salt and let them release their water for 30 minutes, then pat them dry thoroughly.
Making the tomato sauce
- Meanwhile, put the onion in a saucepan and sauté it for 8-10 minutes in 1 Tbsp olive oil. Add the garlic, the tomato paste, a good pinch of oregano (and the chili flakes, if using), and cook for 1 minute. Pour in the crushed tomatoes, season with salt and pepper, add a small glass of water and a drizzle of olive oil. Simmer over low heat for 35-40 minutes (setting 4 on an induction cooktop). Add a little basil at the end of cooking.
- And here’s my tip: blend the sauce in a blender or with an immersion blender. You get a lovely smooth sauce with no bits of onion - and so no kid saying they don’t like it (they loved it!) - it works on reluctant husbands too! ;) The sauce is fairly thick, that’s normal; if your sauce is too runny, you’ll have a hard time cutting clean slices after baking.
Roasting the eggplant
Arrange the eggplant slices on a baking sheet lined with parchment paper. Brush them generously with olive oil on both sides so they cook without burning. Roast at 220°C (425°F) for 25 minutes, turning them halfway through, until they are nicely golden, tender and slightly caramelized around the edges.
Preheat the oven to 190°C (375°F).
Assembling the parmigiana
- In a baking dish, spread a ladleful of tomato sauce evenly over the bottom, then add a layer of eggplant, sprinkle with mozzarella, then grated Parmesan and chopped basil. Repeat, and finish with a layer of eggplant topped with tomato sauce, mozzarella and Parmesan. (I made 3 layers.) Bake for about 25-30 minutes, until the cheese has melted and formed a beautiful golden, bubbling crust. Garnish with whole basil leaves and serve!
Tips and planning
This dish is delicious made the day before and reheated the next day, as the flavors will have melded nicely. In that case, it’s best to bake it 5 minutes less, refrigerate it, and reheat it in the oven the next day (20 minutes at 170°C / 325°F, with the dish covered so it doesn’t dry out).
If you’d like to freeze it, assemble the parmigiana and put it in the freezer. You can also freeze it already baked.
If you have too many roasted eggplant slices, they make a very popular starter or kemia (Tunisian-style appetizer spread)!
