How to Remove Bitterness from Eggplant: Do You Need to Salt and Soak It
Eggplant can taste slightly bitter – that comes from solanine, especially in large, overripe fruit. Young eggplants of modern varieties barely taste bitter, but mature ones are better prepped. Below: why eggplant turns bitter, whether you need to soak and salt it and for how long, and how to make it soak up less oil along the way.
In short: slice the eggplant, sprinkle with salt and leave it for 20–30 minutes – dark juice will be drawn out; drain it, rinse the eggplant in cold water and squeeze. Alternatively, soak it in salted water (1 tbsp of salt per litre) for 20–30 minutes. Young, small eggplants with white seeds needn't be soaked. Bonus: salted and squeezed eggplant absorbs less oil when fried.
Why eggplant tastes bitter
The bitterness comes from solanine – there's more of it in large, overripe fruit with dark, mature seeds. Young eggplants and modern hybrids are barely bitter, if at all. Signs of a bitter eggplant: large, heavy, with brownish flesh and dark seeds. A young one is firm, light, with small white seeds.
Do you need to soak and salt eggplant
Not always. Young, smallish eggplants (roughly up to 300–400 g), firm and with white seeds, can be cooked without prepping. Large and mature ones are better treated. For frying it helps twice over: along with the bitterness you remove excess moisture, so the eggplant soaks up less oil.
How to remove bitterness – 3 methods
| Method | What to do | Time |
|---|---|---|
| Dry salt | slice, sprinkle with salt, toss, let stand and drain the juice | 20–30 min |
| In salted water | soak in a solution (1 tbsp salt per 1 l of water), press down with a weight | 20–30 min |
| Blanching | drop the slices into boiling salted water | 2–3 min |
After any method, rinse the eggplant in cold water and squeeze it (or blot with a towel) – otherwise the dish will be over-salted and watery.
How long to soak eggplant
With salt or in a solution – 20–30 minutes; longer isn't needed, as the eggplant starts to lose its texture. Blanching – 2–3 minutes. The smaller the cut, the faster the bitterness leaves.
Do you need to peel eggplant
Usually the skin is left on – it's edible and helps the pieces hold their shape when frying and baking. Peel it if the skin is tough, the eggplant is overripe, or the dish should be smooth – for caviar, pâtés or eggplants Armenian style.
How to stop eggplant soaking up oil
- Salt and squeeze – less moisture and fewer pores mean less oil absorbed.
- Pat dry the pieces before frying.
- Fry on a well-heated pan; brush the oil on rather than pouring it.
- Best of all – bake in the oven instead of frying: 👉 Baked eggplants in the oven with garlic.
Common mistakes
- Not rinsing after salting – the dish turns out over-salted.
- Soaking too long – the eggplant goes mushy.
- Frying them wet – they soak up oil and spit.
- Cooking a large, overripe one untreated – the bitterness stays.

Once the bitterness is gone, eggplant shines in almost anything:
❓ Frequently asked questions
Do you need to soak young eggplants?
No, if they're small, firm and have small white seeds – those are barely bitter. Mostly it's the large, mature ones that need treating.
How long do you salt eggplant to remove bitterness?
20–30 minutes under salt or in salted water, then rinse in cold water and squeeze.
Can you leave the skin on eggplant?
Yes, the skin is edible and holds the shape. Peel it for purées, caviar and pâtés, or if the skin is tough.
How do you know an eggplant is bitter?
Large, heavy, overripe, with dark-brown seeds – likely bitter. A young one with white seeds isn't.
Does freezing remove bitterness?
No. Before freezing, salt or blanch the eggplant and squeeze it – that removes the bitterness and preserves the texture.
