🍆 How Long to Cook Aubergine in the Oven: A Complete Guide

🍆 Introduction: Getting Aubergine Perfectly Cooked

Oven-cooked aubergine is rich, tender, and full of flavour when done correctly — but undercooking leaves it spongy, while overcooking can dry it out. The exact cooking time depends on how the aubergine is cut, the oven temperature, and whether it’s cooked plain or with oil.

This guide explains how long to cook aubergine in the oven, with clear timings for slices, cubes, halves, and whole aubergines, plus tips to ensure perfect results every time.

🧂 Should You Salt Aubergine Before Baking?

Salting is optional, but useful in some cases.

✔ Benefits of salting:

• Draws out excess moisture
• Improves texture
• Reduces bitterness in older aubergines

How to salt:

1. Slice aubergine
2. Sprinkle lightly with salt
3. Leave 20–30 minutes
4. Rinse and pat dry before cooking

Modern aubergines are usually mild, so salting isn’t always necessary.

🌡️ How to Tell When Aubergine Is Fully Cooked

Perfectly cooked aubergine should be:

✔ Soft all the way through
✔ Golden or lightly caramelised
✔ Easily pierced with a knife
✔ Creamy, not spongy

If the centre feels firm, return it to the oven for 5–10 minutes.
