How to Cook Japanese Sweet Potatoes in the Microwave
Cooking in the microwave is all about efficiency, so let’s break down the steps for how to cook Japanese sweet potatoes perfectly.
Step-by-Step Guide
Step 1: Arrange on a Plate
Place the prepared Japanese sweet potatoes on a microwave-safe plate. Ensure they are spaced out to allow for even heat distribution.
Step 2: Add Moisture
To maintain moisture and enhance steaming, you can add a few tablespoons of water to the plate. If you prefer not to use water, you can cover the potatoes with a microwave-safe plastic wrap or a lid designed for microwaving. This helps create a steamy environment.
Step 3: Microwave Settings
Set your microwave to high power. The cooking time can vary based on the size and number of sweet potatoes you are cooking. As a general guideline:

- 3 medium sweet potatoes: Increase to 12-15 minutes.
Step 4: Check for Doneness
Once the timer goes off, carefully remove the plate (it will be hot!). To check if the sweet potatoes are cooked, insert a fork or knife into the center. The sweet potato should be tender and easily pierced.
If they’re not done, return them to the microwave in 1-minute increments until fully cooked.
Step 5: Let Them Rest
Allow the sweet potatoes to sit for a few minutes after microwaving. This will help them finish cooking and will make them easier to handle.

What are Japanese sweet potatoes, and how do they differ from regular sweet potatoes?
Japanese sweet potatoes, known as “Satsumaimo,” are a variety of sweet potato with a purple or reddish skin and yellowish flesh. They are sweeter and denser than typical orange-fleshed sweet potatoes, providing a unique flavor profile that many find appealing. Their high starch content gives them a creamy texture when cooked, making them perfect for various dishes.
In contrast to regular sweet potatoes, which can have a more earthy taste, Satsumaimo has a distinctive sweetness reminiscent of chestnuts. This difference in flavor makes them popular in Japanese cuisine, where they are often roasted, steamed, or used in desserts. Their nutritional profile is also noteworthy, as they are rich in fiber, vitamins, and antioxidants.
Can I cook Japanese sweet potatoes in the microwave?
Yes, you can definitely cook Japanese sweet potatoes in the microwave, and it’s one of the quickest methods to prepare them. Microwaving retains their natural sweetness and moisture, resulting in a deliciously creamy texture. To ensure even cooking, it’s best to wash them thoroughly, pierce the skin a few times with a fork, and place them on a microwave-safe plate covered with a damp paper towel.
The cooking time will vary based on the size of the sweet potatoes and the power of your microwave. Generally, medium-sized Japanese sweet potatoes take about 5 to 10 minutes. It’s advisable to check for doneness by inserting a fork or knife into the flesh; it should slide in easily when they are cooked perfectly.
What’s the best way to prepare Japanese sweet potatoes before microwaving?
Preparing Japanese sweet potatoes for microwaving is quite straightforward. Begin by washing the potatoes under running water to remove any dirt or debris. After rinsing, dry them with a paper towel and then pierce the skin multiple times with a fork. This step is crucial as it allows steam to escape during cooking, preventing them from bursting.
Once prepared, you can choose to wrap each potato in a damp paper towel or place them directly on a microwave-safe plate. Covering the potatoes helps to maintain moisture and ensures even cooking throughout. If you wish, you can also lightly coat them with oil or sprinkle some salt before cooking, but it’s entirely optional.
How long should I microwave Japanese sweet potatoes?
The cooking time for Japanese sweet potatoes in the microwave typically ranges from 5 to 10 minutes, depending on their size. For average-sized sweet potatoes, starting with 5 minutes on high power is a good idea. After that, check their doneness by inserting a fork or knife into the flesh; it should be soft and tender. If they are still firm, continue microwaving in 1-minute increments until they are fully cooked.
Be mindful that larger sweet potatoes may require more time, while smaller ones will cook faster. It’s often helpful to rotate them halfway through cooking to ensure they are evenly cooked. Always exercise caution when removing them from the microwave, as they may be hot, and let them sit for a minute or two to allow steam to escape.
How do I know when my Japanese sweet potatoes are cooked?
You can tell that Japanese sweet potatoes are cooked when they are fork-tender. After microwaving, take a fork and gently poke the flesh; it should yield easily without any resistance. If you meet with any firmness, that indicates they require more time. Furthermore, you can also visually inspect the skin; it should be slightly wrinkled, indicating that the sweet potato has cooked through.
Another method to test for doneness is to examine the color of the flesh. Once cooked, it will be soft and easily mashable with a fork. If you find that the flesh remains hard or is still opaque, it may need a bit more time in the microwave. Patience is key as it may take a few additional minutes for larger potatoes to reach the desired tenderness.
Can I add seasonings to Japanese sweet potatoes before microwaving?
Absolutely! Adding seasonings to Japanese sweet potatoes can enhance their natural sweetness and flavor. You may choose to use a light drizzle of olive oil, a sprinkle of salt, or even spices like cinnamon or nutmeg, depending on your taste preferences. Applying these seasonings before microwaving helps to infuse the sweet potatoes with delightful flavors during cooking.
Consider experimenting with toppings post-cooking as well. After microwaving, you can top them with butter, honey, or maple syrup for an indulgent treat. Alternatively, adding scallions or sesame seeds can provide a savory touch. Whether you prefer them sweet or savory, Japanese sweet potatoes are versatile enough to accommodate a range of flavor profiles.
Are there any health benefits to eating Japanese sweet potatoes?
Japanese sweet potatoes are not only delicious but also packed with numerous health benefits. They are a rich source of vitamins, particularly vitamin A, which is essential for healthy vision, immune function, and skin health. Additionally, they contain significant amounts of fiber, which helps with digestion and can contribute to feelings of fullness, making them a great option for those watching their weight.
Moreover, they are low in fat and calories, making them a nutritious addition to any diet. The antioxidants present in Japanese sweet potatoes, such as beta-carotene, help combat oxidative stress and may lower the risk of chronic diseases. Incorporating them into your meals can provide you with a flavorful and healthful source of energy.
Can I store leftover cooked Japanese sweet potatoes?
Yes, you can store any leftover cooked Japanese sweet potatoes. It’s best to allow them to cool down to room temperature before placing them in an airtight container. Once properly sealed, you can store them in the refrigerator for up to 3 to 5 days. This makes for convenient meal prep, as you can easily incorporate them into various dishes throughout the week.
If you wish to store them for a longer period, consider freezing them. To freeze cooked Japanese sweet potatoes, let them cool completely, then cut them into desired portions and wrap them tightly in plastic wrap or aluminum foil before placing them in a freezer bag. They can be stored in the freezer for up to three months. When you’re ready to enjoy them, simply thaw and reheat in the microwave or oven.
