By the looks of it, zucchini is a pretty fuss-free food. Compared to other types of squashes and gourds — namely the heavy butternut and pumpkin varieties — zucchinis are like the blameless little siblings, unsuspecting and innocent. You've probably been cutting them up and throwing them in the oven without a second thought. However, it turns out that there's been a bit of a debate surrounding these small, green, seasonal gourds. Like most baby siblings, they're much more complicated than anyone suspected.
So, what is it about these veggies that could be causing such a conundrum in the kitchen? It all has to do with their relationship with salt. It's not about how much of it you should use or what kind — it's about when you should be adding salt to your zucchini. Some people argue that you should salt them before you roast them, while others say that it's simply an unnecessary step nullified by your oven. Different sources say different things and, besides being confusing, it can have serious consequences for yourstuffed zucchini boat dinner. Well, spare your zucchini, because we're getting to the bottom of it.
The case for salting zucchini is much like the case for salting eggplant. In fact, salting before cooking is actually Daniel Boulud's tip for prepping crispier eggplant, and zucchini is much the same.Science is on the side of salting in advance. When salt is sprinkled on the flesh of a water-dense fruit like zucchini and left to sit for a while, a process known as osmosis occurs. In about 20-30 minutes, droplets of water will appear on the surface as physical evidence of the excess moisture being drawn out of your zucchini.
But the question isn't whether or not salting your zucchini beforehand works. The question is if it's actually necessary. Sure, you could take the extra 20-30 minutes to salt your zucchini before you cook it, and it probably would come in handy with especially moist dishes like stuffed zucchini boats where it iseven more difficult to achieve crispiness, but it might not be necessary in every instance. Your oven can handle all of the drying and crisping on its own — or at least, that's what the other side is saying.
The Case For Your Oven
While salt and osmosis can do a handy job of drawing moisture out of your zucchini, so does your oven. That's actually exactly what the oven was designed to do: concentrate your food's flavor by drawing out moisture via the application of heat. It's why other things like bread, meat, and vegetables all come out nicely browned and caramelized without the need for a salt bath. Truth be told, your zucchini can, too. Some claim that waiting to salt zucchini until after it's cooked is actually the secret to getting perfectly roasted zucchini every time.
There are many methods for achieving zucchini with browned skin. Some obvious tactics include cranking your oven's heat up a notch or throwing the sheet pan in while the oven's pre-heating, as is often done with pizza crusts. There's also the basic rule of surface area.Cutting your zucchinis in a way that increases the amount of contact they get with your hot pan will yield crispier results. All of these methods can be utilized on their own or all together to achieve a crispier zucchini without the need for salt. Not to mention, they won't take up any more of your precious time than necessary.
Tossing the zucchini with garlic powder, Italian seasoning, salt, and pepper before baking gives it an amazing foundation of flavor. But adding a few extra seasonings after it roasts really takes it over the top. At a minimum, toss it with a squeeze of lemon juice for bright, fresh flavor.

Salting some meats (especially beef and pork) a few hours before cooking allows the salt to draw out some of the internal moisture, which is then reabsorbed into the meat WITH the salt, thus seasoning from the inside out.
Unless you have time to salt and drain the zucchini, wait to salt it until after they're cooked so the salt doesn't draw out the moisture in the oven—this can lead to sogginess. You can add other seasonings, such as dried herbs and spices, before cooking.
When to Add Salt to Cooking. This depends on what exactly you are cooking and what kind of salt you are using. Salting must be done throughout the entire cooking process, it is not a one and done thing. You want to taste your dish as it cooks and add more salt over time.
Salt most things the day before. Salt bigger cuts and birds at least 2 days in advance. 1.5 teaspoons of kosher salt per pound of meat is a good place to start. If you don't have time to let the meat sit for at least 40 minutes, wait to salt until right before cooking.
“The best times are before the precipitation arrives and it is good to put some down after you finish shoveling or plowing,” Longley explains. By putting salt down after you've cleared your driveway and walkways, you can get ahead of the likely wet surface turning to ice as temperatures drop after sunset.
Though many cookbooks rightly warn you never salt meat or poultry right before you put it in the oven– because the salt will draw out the juices and make it dry and tough–the opposite occurs when you salt well in advance of cooking. It all has to do with the behavior of proteins and cell osmosis.
Additional tips on roasting vegetables. Heavy duty pans are ideal since they allow for even heat distribution and circulation. Because salt draws moisture out of the food, season veggies just before roasting.
For vegetables, chicken, and just about everything else, olive oil and ghee are our first choices for roasting at temperatures over 400°F. Not only do they help food cook up with the crispiness you crave, but each one also imparts its own unique flavor that you just don't get from neutral oils like grapeseed or canola.
Salt the quarters and let them rest for about 10 minutes in a colander. The salt removes water and starts to season the zucchini. After that, dry the zucchini well with paper towels and cook it. High and dry-heat cooking, like grilling or sautéing work best for zucchini.
Slice and salt zucchini in advance of cooking to draw out some of the vegetable's excess moisture (while also seasoning it more thoroughly). To do this, cut up a pound of zucchini and toss it with ½ teaspoon of table salt. Let it drain in a colander for about 30 minutes before patting it dry and cooking it.
Vegetables with high water content tend to become mushy and bland if they aren't rid of excess moisture before cooking. To do that, you need two things: salt and time. Salting these watery vegetables draws out extra water and flavor molecules.
So, boiling in heaps of water can lead to some loss of water soluble vitamins. One study looking at the effects of boiling on different veggies found boiling spinach and broccoli could reduce the vitamin C content by 50% or more, and boiling courgette / zucchini and sweet potato reduced the vitamin C by about a third.
