Why roast eggplants before rolling them
Everything starts with how you cook the eggplants. Thinly sliced and roasted in the oven, they become tender and develop a subtle smoky note typical of southern cuisine — unlike raw eggplant, which stays firm and can taste bitter. Above all, roasting makes the slices pliable enough to roll without breaking.
Aim for slices that are golden, with slightly caramelized edges, but still intact. They should be neither dry nor so soft that they tear; this balance helps the rolls hold together and remain juicy once baked with the gratin.
Ingredients for baked eggplant rolls
Serves 4.
- 3 large eggplants (about 900 g)
- 4 tablespoons olive oil (about 60 ml)
- 1 teaspoon fine salt
- ½ teaspoon black pepper
- 250 g ricotta
- 1 garlic clove (grated or pressed)
- 1 teaspoon dried thyme (or 1 tablespoon fresh thyme)
- 30 g grated Parmesan
- 500 g tomato passata
- 1 teaspoon sugar (optional)
- 200 g grated mozzarella (or grated Emmental)
- 8 basil leaves (optional, for serving)
Steps, from roasted slices to gratin
- Preheat the oven to 190 °C. Slice the eggplants lengthwise into 5 mm slices, brush them with oil and season. Roast on a baking sheet for about 18 to 22 minutes, until they soften and show a nice color at the edges.
- Make the filling by mixing the ricotta with the grated garlic, thyme and Parmesan until smooth and creamy.
- Spoon a layer of tomato passata into the bottom of a baking dish; add a pinch of sugar if the sauce is too acidic.
- Place a small spoonful of filling at the base of each slice, roll it up tightly, and arrange the rolls side by side in the dish.
- Pour the remaining passata over the rolls and sprinkle with mozzarella. Return to the oven for 15 to 20 minutes, until the top is golden and bubbling. Garnish with basil and serve hot.
How to roll without tearing the slices
A few simple tips ensure neat rolls. Use only a small amount of the ricotta filling at the start of each slice so the filling stays centered and doesn’t spill during baking. Roll firmly but gently while the eggplant is still flexible.
Adding passata both under and over the rolls prevents drying and helps the sauce meld. For the topping, mozzarella melts and browns nicely; Emmental yields a more pronounced gratin, and a touch of Parmesan in the filling enhances the crust.
Pairings and variations
Serve these rolls family-style in the center of the table, alongside a crisp green salad or steamed new potatoes. For drinks, a chilled rosé or a homemade lemonade complements the sunny flavors.
To vary the recipe, add a pinch of chili to the ricotta for a spicy kick, stir diced black olives into the passata for extra aroma, or fold in a little feta or preserved lemon to push the dish further into Mediterranean territory.
