Parmigiana di Melanzane

For the aubergines

• 4 medium aubergines, ~1 kg total, Italian long or Swiss summer aubergines
• 1 tbsp coarse sea salt, for degorging
• 250 ml olive oil or HOLL rapeseed oil, for frying
• 4 tbsp 00 flour, for dusting before frying

For the tomato sauce

• 800 g canned whole peeled San Marzano DOP tomatoes, or 1 kg ripe summer tomatoes, peeled and seeded
• 2 garlic cloves, lightly crushed
• 2 tbsp extra-virgin olive oil, for the sauce
• a pinch peperoncino flakes, optional, for the sauce(optional)

For the layers and finish

• 250 g fior di latte or mozzarella di bufala Campana DOP, well-drained; lactose-free equivalent works identically
• 60 g Parmigiano Reggiano 30+ months or Swiss Sbrinz AOP 22+ months, finely grated
• 1 bunch fresh Genovese basil, stems for the sauce, leaves for layers and finish
• 1 tbsp extra-virgin olive oil, peppery Sicilian or Pugliese, for finishing
• to taste black pepper, freshly ground

Degorge the aubergines

1. 1

   Cut the aubergines lengthwise into 7 mm slices (6 mm if oven-roasting). Use a sharp knife — dull blades tear the flesh and create channels for oil to enter. Layer the slices in a colander, salting each layer with coarse sea salt (about 1 tsp per medium aubergine total). Stack a plate on top, then a 1–2 kg weight, set the colander in the sink, and leave 45–60 minutes. You are not removing bitterness — you are partially collapsing the cell walls so the slices absorb less oil and hold their texture.

   Do not skip the weight — it doubles the moisture extraction. You should see a pool of brown liquid in the sink.

Make the tomato sauce

1. 2

   Pour 2 tbsp olive oil into a wide pan over cold heat. Add the lightly crushed garlic cloves to the cold oil, then bring to medium. This extracts garlic flavour without browning it. Cook 3–4 minutes until the cloves are soft and golden but not coloured.

   Tip: Garlic dropped into already-hot oil burns in seconds and turns acrid.

2. 3

   Hand-crush the tomatoes — do not blend, as blending whips in air and lightens the colour. Add them to the pan with a few basil stems and a pinch of peperoncino if using. Bring to a vigorous simmer with a splatter screen on, and reduce uncovered by 30–40% (from ~750 ml to about 500 ml). This takes 20–25 minutes in a wide pan. Stir occasionally.

   Do not cover the pan — covering traps steam and defeats the reduction.

   Off the heat, fish out the garlic cloves and basil stems. Pass through a food mill for the silkiest texture, or leave slightly rustic. Season with salt now, not at the start, as salt concentrates during reduction. Tear in 4–5 fresh basil leaves and stir. The sauce should taste round and slightly sweet with no harsh acid edge.

   3m

   Tip: If genuinely sharp, a pinch of sugar is acceptable — but good San Marzano shouldn't need it.

Prepare the mozzarella

1. 5

   Tear the mozzarella into rough 2 cm pieces and lay them on a doubled paper towel. Salt very lightly and leave for at least 30 minutes — fresh mozzarella is 50–60% water, and any moisture not pulled out here will flood the bake. Once drained, return the pieces to the fridge for the final 15–30 minutes before assembly.

   30m

   Cold, well-drained mozzarella firms the curd and reduces water release in the oven. Do not skip this, especially with bufala.

Rinse, dry and fry the aubergines

1. 6

   Rinse the slices thoroughly under cold running water — salt trapped in the collapsed flesh needs a few seconds per side. Then dry rigorously between paper towels, pressing firmly. Damp slices spatter in hot oil and steam rather than fry.

   5m

   Inadequate rinsing gives a brutally salty dish; damp slices will not brown.

2. 7

   Spread the 00 flour on a wide plate. Dust each slice and shake off the excess vigorously — you want the lightest possible coating. Heat the frying oil to 170–180°C, using a thermometer. Fry the slices in batches in a single layer, about 90 seconds per side, until evenly golden-amber. Let the oil recover to 180°C between batches. Drain on a wire rack over paper towels.

   Below 160°C the slices absorb oil before browning; above 190°C the surface scorches. Crowding the pan drops the oil temperature instantly.

Assemble

1. 8

   Preheat the oven to 200°C conventional heat (no fan). Use a ceramic or glass dish, ~22×16 cm and 5–6 cm deep. Spread 2–3 tbsp of tomato sauce thinly across the bottom to prevent sticking and create a steam buffer.

   Tip: Avoid metal except heavy enamelled cast iron — metal transfers heat too aggressively at the edges.

2. 9

   Build three full layers, in this order each time: a single layer of aubergine slightly overlapping, ~4 tbsp tomato sauce spread evenly, a few torn basil leaves, about one-third of the mozzarella scattered (not in clumps), and about one-quarter of the grated hard cheese. Press gently with your palm after each layer to eliminate air pockets.

   10m

   Aim for bonding, not flooding — if sauce drips out when you slice the finished dish, you used too much.

3. 10

   For the top layer, do aubergine, then a slightly more generous spread of sauce, torn basil, and the remaining grated hard cheese only. No mozzarella on top — it turns into a rubbery cap, whereas parmigiano or Sbrinz crusts into the textural contrast you want.

   3m

Bake and rest

1. 11

   Place the dish in the middle of the oven, immediately drop the temperature to 180°C, and bake for 30 minutes. Then raise to 200°C for the final 5–10 minutes to crisp the top. The dish is done when bubbling is visible across the entire top — not just the edges — and the top is golden-brown with some darker spots.

   40m180°C then 200°C

   If only the edges are bubbling and the centre looks still, give it another 5 minutes.

2. 12

   Rest 20 minutes uncovered. The interior is structurally fluid straight out of the oven and cannot be sliced cleanly without resting. Resting also brings the dish to optimal eating temperature (~55–65°C), where flavour perception is markedly more vivid.

   20m

   Resting is non-negotiable for clean slices.

3. 13

   Drizzle the finishing olive oil over the rested dish in a thin stream and scatter a few torn fresh basil leaves. Slice with a serrated knife or wide pie server and lift portions out with a flat spatula. A properly executed slice holds its shape on the plate with visible strata.
