How to grill the Zucchini, Japanese style

A zucchini is from the family of Cucurbita pepo which the pumpkin, squash, and cucumber also belong to. This vegetable can grow up to a meter long and is quite delicious when cooked with the right ingredients and heat.

When used for food, zucchini is usually picked when under 20 cm (8 inch) in length, preferably with the flower still attached to it because it is believed that at this age the vegetable is immature with its seeds still soft and is perfect for consumption.

Much like the squash and pumpkin, the zucchini is usually served cooked and only the cucumber is an exception as it can be eaten fresh.

It can be prepared using a variety of cooking techniques, including steamed, boiled, grilled, stuffed and baked, barbecued, fried, or incorporated in other recipes such as soufflés.

Let’s look at the first Zucchini recipe you can make on your Japanese Teppanyaki grill (or just using your grilling pan if you don’t have one):

Japanese grilled zucchini and green onions

Joost Nusselder
If you’ve ever been in one of those Japanese steakhouses, then you must have tried the grilled zucchini – it makes a tender and flavorful side dish for the steak.

The sesame seeds and soy sauce give the vegetables a robust flavor. Instead of having other high-carb side dishes choose the potassium and calcium-rich zucchini instead. A popular summer squash, the zucchini is sometimes called a courgette.

If you’ve ever been in one of those Japanese steakhouses, then you must have tried the grilled zucchini – it makes a tender and flavorful side dish for the steak.

The sesame seeds and soy sauce give the vegetables a robust flavor. Instead of having other high-carb side dishes choose the potassium and calcium-rich zucchini instead. A popular summer squash, the zucchini is sometimes called a courgette.

In Japanese restaurants, it is often served with rice along with the steak, shrimp or chicken you’ve ordered. In order to get the best results, then you may want to grill the zucchini on a teppanyaki griddle, but don’t overcook them or else they won’t be crispy and crunchy but instead mushy.

Here’s how to make it:

three zucchini recipes

You can also bake the zucchini into the bread like the banana bread or make a zucchini cake which should have a similar baking method to the carrot cake or apple pie.

When marinated or stuffed the flower of the zucchini is also a delicacy and can be eaten as tempura when deep fried.

Zucchini has a delicate flavor and requires little more than quick cooking with butter or olive oil, with or without fresh herbs. You don’t have to peel off the skin as it is also edible.

The zucchini has at least 30% – 40% water in it and when cooked quickly in oil or butter it will momentarily boil/steam on the grill, once the water evaporates and the juices concentrate, then it will give off a very distinct taste which is what the fruit is known for.

You can also eat the zucchini raw, sliced or shredded like in a refrigerated salad or the lightly cooked Vietnamese or Thai hot salads. Mature (larger sized) zucchini are well suited for cooking in bread.

If you’ll use a spiralizer, then you can make low-carb highly nutritious noodles recipes out of the zucchini too!

Zucchini Nutrition Facts

Zucchini nutrition facts

Since we’ve pretty much covered everything about how to cook the zucchini in a teppanyaki grill, then it’s time to find out what sort of benefits we can get out of this fruit/vegetable. The zucchini – a summer squash – has lots of carotenoids, the naturally occurring compound found in plants which are also known as Vitamin A.

A new research suggested that the vegetable has the highest concentration of carotenoids than any other plant in the Cucurbita pepo family! One of the top 3 sources of the most revered antioxidant compounds lutein, zeaxanthin, and beta-cryptoxanthin, the summer squash truly is indeed a miracle plant.

1.) Zucchinis are Great for Blood Sugar

While insulin is quite an expensive drug sold in pharmacies, you can get the same benefit from the zucchini which can help control your blood sugar level.

• The B-complex vitamins are all critically important for the metabolism of sugar. They help break down carbohydrates and convert them into energy for our body to use. Lack of these essential vitamins will cause carbs to break down into sugars and overwhelm the body’s insulin which can lead to diabetes. Since zucchinis are loaded with vitamins B6, B1, B2, B3, and choline, they are best suited to regulate blood sugar levels and help slow the progress of diabetes in your body. Equally important for the regulation of blood sugar is the zinc that’s present in the zucchini.
• Omega-3 fatty acids are another chemical compound that helps blood sugar regulation.
• The magnesium in zucchinis also helps maintain your blood pressure as well as break down carbohydrates.

2.) Zucchini is Great for Cardiovascular Health

Vitamin C and manganese which are also present in the zucchini helps keep your cardiovascular system in check.

• Vitamin C is like your go-to guy for whatever you need because it helps just about every other nutrient perform their function in your body in order to keep you healthy. Its antioxidant properties help you defend against cardiovascular diseases.
• Research shows that there is a link between manganese deficiency and diabetes, if you eat zucchini regularly, then it should prevent your body from developing diabetes.
• Omega-3s help to sweep LDL (low-density lipoprotein) from the bloodstream and the zucchini has got it in spades. LDL cholesterol is troublesome because they tend to stick to arterial walls or slip through them and stick to your other internal organs, which can have much worse effects.

3.) Zucchini is a Good Anti-Inflammatory

When a foreign pathogen (bacteria, virus or microorganism) enters our body, it responds by causing inflammation in infected areas. This is the body’s natural defenses acting against those foreign substances in order to flush them out. In some cases, inflammation happens even when it is not needed and this can lead to severe pain in various organs or tissues in your body.

The summer squash contains nutrients that heal inflammation caused by an overactive immune system.

• Omega 3 fatty acids are excellent for countering inflammations plus it also helps prevent the arteries from hardening.
• Carotenoids, like beta-carotene, zeaxanthin, and lutein, are found to be anti-inflammatory compounds.
• Summer squash fibers contain polysaccharides have been lab tested and proven to heal inflammation.
• The zucchini has been found by researchers to be very effective at treating gastrointestinal tract and cardiovascular system inflammations. For this reason, doctors advise patients who are suffering from gastric ulcers and duodenal ulcers to include zucchinis in their diet as part of their treatment.
