Aubergine parmigiana is a dish built on patience – salting, roasting, layering. This version uses whole spelt breadcrumbs on top instead of the usual white crumb, which adds a gentle nuttiness and holds its texture better through the bake.
The tomato sauce is simple: garlic, good canned tomatoes, and a little time on the hob. Nothing extra. The aubergine does most of the flavour work once it has time in the oven.
This is a reliable dish for a midweek dinner or a casual gathering. You can build the whole thing ahead of time and refrigerate it, then bake when needed. The layers hold well and the flavours stay clean.

- One baking dish, straightforward steps throughout.

Ingredient Notes
- Aubergine: Salting draws out moisture and reduces bitterness. Pat dry thoroughly before roasting or the layers turn watery.
- Spelt breadcrumbs: Use day-old spelt bread blitzed coarsely. A fine crumb compacts too much and loses that open, crisp texture on top.
- Mozzarella: Low-moisture mozzarella melts more evenly and releases less water than fresh. If using fresh, pat the slices dry with paper towels first.
- Canned tomatoes: Whole plum tomatoes crushed by hand give better texture than pre-chopped. San Marzano work well but any good-quality brand is fine.
- Parmesan: Grate fresh for best flavour. A vegetarian hard cheese works as a direct swap if you need a rennet-free option.
- Olive oil: Use a mid-range olive oil for roasting the aubergine. Save a good extra-virgin drizzle for the top before serving if you like.

Ingredients
Aubergine
Tomato Sauce
Assembly and Topping
Instructions
Salt and Roast the Aubergine
- Lay the aubergine slices in a single layer in a colander. Sprinkle both sides with fine sea salt and leave for 30 minutes until moisture beads on the surface.
- Rinse the slices under cold water and press firmly between a folded tea towel until dry.
- Heat the oven to 200 C / 390 F. Arrange the aubergine on two large baking sheets in a single layer. Brush both sides with olive oil.
- Roast for 20 to 25 minutes, flipping halfway, until golden and soft. Set aside.
Make the Tomato Sauce
- Heat 2 tbsp olive oil in a medium saucepan over medium heat. Add the garlic and cook for 1 to 2 minutes until softened but not coloured.
- Add the crushed tomatoes and oregano. Season with salt and pepper.
- Simmer uncovered for 20 minutes, stirring occasionally, until the sauce thickens and clings to a spoon. Stir in the torn basil and remove from heat.
Prepare the Spelt Crumb Topping
- Blitz the day-old spelt bread in a food processor until you have coarse crumbs. Tip into a small bowl, add 1 tbsp olive oil and a pinch of black pepper, and toss to combine.
Assemble and Bake
- Spread a thin layer of tomato sauce across the base of a deep 20x30 cm baking dish.
- Add a layer of roasted aubergine slices, slightly overlapping. Spoon over more tomato sauce and scatter over some mozzarella and a little Parmesan.
- Repeat the layers - aubergine, sauce, mozzarella, Parmesan - until all the aubergine is used. Finish with a final layer of sauce, the remaining mozzarella, and a generous scatter of Parmesan.
- Spread the spelt crumbs evenly over the top.
- Bake at 200 C / 390 F for 20 to 25 minutes until the crumb topping is golden and the cheese is bubbling around the edges.
- Remove from the oven and rest for 10 minutes before slicing and serving.

Additional Notes
- Salt aubergine slices for at least 30 minutes before roasting for best results.
- Do not skip the resting step after baking - 10 minutes keeps layers intact.
- Add spelt crumbs only in the final layer to maintain a crisp top.
- Sauce must be reduced and thick before layering to avoid a watery bake.
- Use low-moisture mozzarella or pat fresh mozzarella completely dry before use.
