Aubergines, also known as eggplants, are a staple ingredient in many cuisines around the world. Whether you’re making a hearty ratatouille, a rich eggplant parmesan, or simply roasting them as a side dish, aubergines are a versatile and delicious addition to any meal. However, one question has long plagued home cooks and professional chefs alike: do you need to soak aubergine before roasting? In this article, we’ll delve into the world of aubergine preparation and explore the benefits and drawbacks of soaking this beloved vegetable.
The Case for Soaking Aubergine
Soaking aubergine before roasting is a common practice that has been passed down through generations of cooks. The idea behind this technique is to remove excess moisture from the aubergine, which can make it more prone to absorbing oil and becoming greasy during the roasting process. By soaking the aubergine in saltwater or a brine solution, you can help to draw out some of this excess moisture, resulting in a crisper, more flavorful final product.
But that’s not all – soaking aubergine can also help to reduce its bitterness. Aubergines contain a number of compounds that can give them a bitter taste, including solanine and chlorogenic acid. By soaking the aubergine, you can help to break down these compounds and reduce the overall bitterness of the vegetable.
The Science Behind Soaking Aubergine
So, how exactly does soaking aubergine work? The process is based on a principle called osmosis, which is the movement of water molecules from an area of high concentration to an area of low concentration. When you soak an aubergine in saltwater, the water molecules in the aubergine are drawn out into the surrounding liquid, taking some of the excess moisture with them. This helps to reduce the overall water content of the aubergine, making it more suitable for roasting.
But what about the bitterness-reducing effects of soaking aubergine? This is due to the fact that the compounds responsible for the bitterness of aubergines are water-soluble. By soaking the aubergine, you can help to break down these compounds and reduce their concentration in the vegetable.
The Case Against Soaking Aubergine
While soaking aubergine can be beneficial in some ways, it’s not a necessary step in every recipe. In fact, some cooks argue that soaking aubergine can actually do more harm than good.
One of the main drawbacks of soaking aubergine is that it can make the vegetable more prone to absorbing oil. While it’s true that soaking can help to remove excess moisture from the aubergine, it can also make it more porous and susceptible to oil absorption. This can result in a greasy, unpleasant texture that’s not ideal for every recipe.
Another argument against soaking aubergine is that it can be a time-consuming and unnecessary step. If you’re short on time or prefer a more streamlined cooking process, you may not want to bother with soaking your aubergine.
Alternative Methods for Preparing Aubergine
If you don’t want to soak your aubergine, there are still plenty of ways to prepare it for roasting. Here are a few alternative methods you can try:
- Salt and drain: Instead of soaking your aubergine, you can try salting it and letting it drain for 30 minutes to an hour. This can help to remove excess moisture and reduce bitterness without the need for soaking.
- Pat dry: Another option is to simply pat your aubergine dry with a paper towel before roasting. This can help to remove excess moisture and promote even browning.
Roasting Aubergine: Tips and Techniques
Whether you choose to soak your aubergine or not, there are a few key tips and techniques to keep in mind when roasting this versatile vegetable.
- Choose the right variety: Not all aubergines are created equal. For roasting, you’ll want to choose a variety that’s high in flesh and low in seeds, such as the popular globe or Italian eggplant.
- Cut correctly: The way you cut your aubergine can make a big difference in the final texture and flavor. Try cutting it into thick slices or wedges for a meaty, satisfying texture.
- Season liberally: Aubergine can be a bit bland on its own, so be sure to season it liberally with salt, pepper, and any other herbs or spices you like.
- Roast at the right temperature: For a crispy exterior and a tender interior, try roasting your aubergine at a high temperature (around 425°F/220°C) for a shorter amount of time (around 20-30 minutes).
Roasting Aubergine: A Basic Recipe

What is the purpose of soaking aubergines before roasting?
Soaking aubergines before roasting is a common practice that serves several purposes. The primary reason is to remove excess moisture from the vegetable, which can make it more tender and less prone to bitterness. By soaking the aubergine in saltwater or a brine solution, the excess moisture is drawn out, resulting in a more even texture and flavor.
Additionally, soaking can help to reduce the amount of oil absorbed by the aubergine during the roasting process. Aubergines have a tendency to absorb a lot of oil, which can make them taste greasy and heavy. By removing excess moisture, the aubergine is less likely to absorb as much oil, resulting in a lighter and more flavorful dish.
What are the benefits of not soaking aubergines before roasting?
Not soaking aubergines before roasting can also have its benefits. For one, it saves time and effort in the preparation process. Simply slicing or chopping the aubergine and tossing it with olive oil, salt, and other seasonings can result in a delicious and flavorful dish. Additionally, not soaking the aubergine can help preserve its natural texture and flavor.
Some argue that soaking aubergines can result in a loss of flavor and texture, as the vegetable can become waterlogged and bland. By not soaking the aubergine, the natural sweetness and depth of flavor can be preserved, resulting in a more vibrant and delicious dish.
How do I soak aubergines before roasting?
To soak aubergines before roasting, start by slicing or chopping the vegetable into the desired shape and size. Next, place the aubergine pieces in a bowl or container and cover them with saltwater or a brine solution. The general ratio is 1 tablespoon of salt to 1 cup of water. Let the aubergine soak for at least 30 minutes to an hour, or up to several hours in the refrigerator.
After soaking, remove the aubergine from the liquid and pat it dry with paper towels to remove excess moisture. Then, toss the aubergine with olive oil, salt, and other seasonings before roasting in the oven.
What is the best way to roast aubergines?
The best way to roast aubergines is to preheat the oven to a high temperature, typically around 425°F (220°C). Toss the aubergine pieces with olive oil, salt, and other seasonings, such as garlic, herbs, or spices. Spread the aubergine out in a single layer on a baking sheet and roast for 20-30 minutes, or until the vegetable is tender and caramelized.
It’s also important to not overcrowd the baking sheet, as this can prevent the aubergine from cooking evenly. Instead, roast the aubergine in batches if necessary, to ensure that each piece has enough room to cook properly.
Can I use other methods to remove excess moisture from aubergines?
Yes, there are other methods to remove excess moisture from aubergines besides soaking. One method is to salt the aubergine and let it sit for 30 minutes to an hour before rinsing and patting it dry. This method is often referred to as “degorging” the aubergine.
Another method is to use a salad spinner or clean kitchen towel to gently squeeze out excess moisture from the aubergine. This method is quick and easy, and can be used in conjunction with soaking or salting to remove excess moisture.
Are there any specific types of aubergines that benefit from soaking?
Some types of aubergines may benefit more from soaking than others. For example, larger, more bitter aubergines may benefit from soaking to remove excess moisture and bitterness. On the other hand, smaller, sweeter aubergines may not require soaking, as they tend to be less bitter and have a more delicate flavor.
It’s also worth noting that some varieties of aubergine, such as Japanese or Chinese eggplant, may be more prone to bitterness and benefit from soaking. However, this can vary depending on the specific variety and growing conditions.
Can I soak aubergines ahead of time and store them in the refrigerator?
Yes, you can soak aubergines ahead of time and store them in the refrigerator. In fact, soaking the aubergine and letting it sit in the refrigerator for several hours or overnight can help to remove excess moisture and bitterness.
However, it’s best to pat the aubergine dry with paper towels before storing it in the refrigerator to prevent excess moisture from accumulating. Additionally, be sure to cook the aubergine within a day or two of soaking, as it can become soggy and develop off-flavors if stored for too long.
