Roasted Aubergine with Herb Olive Oil
Overview
This aubergine dish is built around a two-stage roasting method: first to soften and caramelise the flesh, then to absorb a late-added herb oil that carries garlic, thyme, rosemary, and chilli. Adding the oil toward the end prevents scorching while allowing the aubergine to soak up flavour and develop a glossy finish.
A small drizzle of balsamic vinegar at serving sharpens the dish and balances the richness of the olive oil.
Ingredients (serves 4)
- 1 large aubergine (~450 g / 1 lb, approx)
- 30 ml (2 tbsp) olive oil (for initial roasting)
- salt
Herb olive oil
- ~1 g (1 tsp chopped rosemary leaves, approx)

3. Prepare the herb oil

Transfer to a plate and drizzle lightly with balsamic vinegar just before serving.
Serving Suggestions
Serve alongside roasted meats, poultry, or grain-based dishes.
Pairs especially well with:
Notes
- Aubergine absorbs oil readily; adding the herb oil late prevents it becoming greasy.
- Grinding the herbs releases aroma and helps them disperse evenly.
- Balsamic vinegar adds acidity and contrast without masking the herb flavours.
Brain Health Notes
- Aubergine provides fibre and polyphenols that support gut microbiome diversity and contribute to antioxidant networks.
- Rosemary and thyme are rich in polyphenols and terpene compounds that have been studied for antioxidant and anti-inflammatory effects.
- Extra-virgin olive oil contributes monounsaturated fats and phenolic compounds associated with cardiometabolic and brain health.
