Zucchini is a popular summer squash that is featured heavily in many dishes. Before cooking zucchini, many people soak it in salt water which is a somewhat controversial technique. Here is a comprehensive look at soaking zucchini in salt water – the reasons for doing it, how to do it properly, and whether it’s really necessary.
What Does Soaking Zucchini in Salt Water Do?
The main reason people soak zucchini in salt water is to draw out excess moisture and bitterness.
Zucchini, like other summer squashes, contains a lot of water. As a result, it can easily become soggy and mushy when cooked. Soaking slices or cubes of zucchini in salt water helps pull out some of this moisture ahead of time so the vegetable doesn’t get overcooked.
In addition to moisture, soaking is said to remove some of the bitterness from zucchini. The fruits can sometimes have a bitter flavor, particularly larger, overmature zucchinis. The salt helps draw out some of these bitter compounds.
Does Soaking Really Make a Difference?
Many cooks insist that saltwater soaking makes a big difference in the texture and taste of cooked zucchini. However, others argue that the effects are negligible and not worth the time and effort.
Some tested side-by-side and found soaked zucchini to be slightly less moist but not significantly different in taste. The bitterness was not noticeably reduced either. These results suggest soaking may extract a small amount of moisture but does not drastically alter the squash.
Much of the effect attributed to soaking may come down to proper cooking methods. If zucchini is cooked thoroughly and the moisture is allowed to evaporate, it will avoid becoming mushy regardless of pre-soaking. Proper seasoning and pairing with ingredients that complement zucchini’s flavor can mask any remaining bitterness.
How to Soak Zucchini
If you do want to soak your zucchini, here is a simple process:
1. Wash and trim zucchini, then slice or cube it.
2. Place the cut zucchini in a colander or bowl. Sprinkle several teaspoons of salt over the top and toss to evenly coat the pieces.
3. Allow to rest for 30-60 minutes, tossing occasionally. The salt will draw moisture out of the zucchini, creating beads of water.
4. Rinse the zucchini under cold water to remove excess salt.
5. Pat dry with paper towels or a clean dish towel.
The zucchini is now ready to be cooked or added to recipes.
Tips for Soaking Zucchini
Here are some tips to keep in mind when soaking zucchini:
- Use 1-2 teaspoons of salt per pound of trimmed zucchini.
- Slice zucchini no more than 1/4-inch thick for best results.
- Larger slices or cubes may need up to 2 hours soak time.
- Soak at room temperature instead of chilled water.
- Stir or turn the zucchini occasionally while soaking.
- Rinse well and pat dry thoroughly after soaking.
When Should You Avoid Soaking?
For some recipes and cooking methods, soaking zucchini is unnecessary or even detrimental:
- Grilling – Soaking can make grilled zucchini mushy. Grill untreated slices directly.
- Roasting – Dry, unsalty zucchini caramelizes better when roasted.
- Quick cooking – If cooking zucchini quickly over high heat, don’t soak.
- Added moisture – When adding zucchini to soups, stews, etc. soaking is unnecessary.
- Salting later – If salting for flavor, salt during or after cooking instead.
Conclusion
Soaking zucchini in salt water before cooking is a common technique said to reduce moisture and bitterness. However, tests show the effects may be minimal for most types of zucchini. For many recipes, soaking is unnecessary and can negatively impact the texture.
If you want to try soaking, use 1-2 tsp of salt per pound of zucchini slices and soak 30-60 minutes. Rinse, pat dry, and proceed with your cooking method. Avoid soaking when grilling, roasting, or adding to wet dishes. Determine if the extra time and effort makes a noticeable difference in your finished dishes.
Proper seasoning and cooking methods like sautéing, baking, or steaming likely have a bigger impact on maximizing zucchini’s flavor and texture. But soaking may be worth doing if you find it improves the zucchini for your preferences and recipes.
