Key Takeaways

  • 🍚 If using a microwave to reheat the rice, sprinkling some water on it or covering it with a damp paper towel can help restore moisture.
  • 🍣 Assembling everything except for the nori and wrapping it tightly in plastic wrap the night before could be a solution, and then office workers can wrap the nori themselves on the day of eating.
  • 🥬 There are differing opinions about marinating the spam in soy sauce and using furikake due to their high salt content.

Best Ways to Reheat Spam Musubi

As a big fan of Spam Musubi, I know that reheating it properly is crucial to maintain its deliciousness. Here are the best ways to reheat Spam musubi that I have found.

Microwave Method

The microwave method is the quickest and easiest way to reheat Spam musubi. Simply place the musubi on a microwave-safe dish and cover it with a slightly damp paper towel. Microwave on a low heat setting for about one minute. This will help trap in moisture and prevent the rice from drying out. However, be aware that microwaving may change the texture of the seaweed.

Oven Method

If you have more time, the oven method is a great option. Preheat your oven to 350°F and place the Spam musubi on a baking sheet. Cover the musubi with aluminum foil to prevent the rice from drying out. Bake for about 10-15 minutes or until the musubi is heated through. This method will help to maintain the texture of the seaweed and rice.

Pan-frying Method

The pan-frying method is another great option for reheating Spam musubi. Heat a non-stick pan over medium heat and add a small amount of oil. Place the Spam musubi in the pan and cook for about 2-3 minutes on each side or until heated through and crispy. This method will give the musubi a nice crispy texture.

Overall, these are the best ways to reheat Spam musubi. Choose the method that works best for you and enjoy your delicious Spam musubi.

Tips to Ensure Quality Reheating

When reheating Spam Musubi, there are a few tips that can help ensure that the quality of the dish is maintained. Here are some things that I always keep in mind when reheating Spam Musubi:

Thaw Before Reheating

If you have frozen Spam Musubi, you should thaw it before reheating it. This will help ensure that the Spam Musubi heats evenly. You can thaw Spam Musubi in the refrigerator overnight or by placing it in the microwave on the defrost setting.

Use a Damp Paper Towel

When reheating Spam Musubi in the microwave, it’s important to use a damp paper towel to cover the dish. This will help prevent the rice from drying out and becoming hard. The damp paper towel will also help create steam, which will help heat the Spam Musubi evenly.

Don’t Overheat

Overheating Spam Musubi can cause the rice to become hard and the Spam to become dry. To prevent this, I recommend reheating Spam Musubi in short intervals of 30 seconds to 1 minute. After each interval, check the Spam Musubi to see if it’s heated through. If it’s not, continue reheating in 30-second intervals until it’s heated through.

Add Fresh Ingredients

To give reheated Spam Musubi a fresh taste, you can add some fresh ingredients. For example, you can add a slice of avocado, a sprinkle of furikake, or a drizzle of soy sauce. These fresh ingredients will help add flavor and texture to the reheated Spam Musubi.

While reheating Spam Musubi is relatively straightforward, there are a few common mistakes that can affect the quality of your dish. Here are some things to avoid:

Using High Heat Using high heat can cause the Spam and rice to dry out quickly and become hard. Always use a low to medium heat setting when reheating Spam Musubi, whether you’re using a microwave, oven, or stovetop.

Not Covering the Musubi Not covering the musubi when reheating can lead to dryness. Always cover your Spam Musubi with a damp paper towel or aluminum foil to trap in moisture and prevent the rice from drying out.

Reheating for Too Long Reheating Spam Musubi for too long can cause the rice to become hard and the Spam to become dry. Always reheat in short intervals and check the musubi after each interval to ensure it’s heated through.

Not Thawing Frozen Musubi If you’re reheating frozen Spam Musubi, it’s important to thaw it first. Not thawing the musubi can result in uneven heating, with the outside becoming hot while the inside remains cold.

By avoiding these common mistakes, you can ensure that your reheated Spam Musubi is delicious and enjoyable.

How to keep the nori (seaweed wrapper) crispy and fresh

  1. Keep the Nori Separate: Many of the Reddit users recommend keeping the nori separate from the rice until you’re ready to eat the musubi. This prevents the nori from absorbing moisture from the rice and becoming soggy. This advice was inspired by the way pre-made onigiri (rice balls) are packaged in Japan, where the nori is kept separate from the rice by a layer of plastic until the point of consumption.
  2. Wrapping and Storing: If you’re making musubi ahead of time, one user suggests tightly wrapping them in plastic wrap and storing them in the refrigerator. You can then microwave them for 10-15 seconds to warm them up before eating. Another user suggested sprinkling water over the rice or covering it with a damp paper towel when microwaving, to prevent the rice from drying out.
  3. Use a Rice Cooker: If you have a rice cooker with a warming setting, you can cook the rice ahead of time and it will maintain its consistency until the morning.
  4. Additional Ingredients: A few users discussed adding ingredients like furikake (a Japanese seasoning), scrambled egg, or pickled daikon to the musubi. One person specifically recommended against making musubi without furikake, calling it “a sin”.
  5. Using Sushi Rice: There was a suggestion to use sushi rice (rice seasoned with vinegar, sugar, and salt) for making musubi.
  6. Packaging Mystery: One user was specifically curious about how the onigiri are packaged in a way that keeps the nori crisp and separate from the rice, admiring it as a marvel of engineering.


Reheating Spam Musubi doesn’t have to be a daunting task. By following these simple tips and techniques, you can enjoy your Spam Musubi as if it were freshly made. Whether you prefer the quick and easy microwave method, the oven method that maintains the texture, or the pan-frying method that adds a crispy touch, there’s a method that’s perfect for you. Remember to avoid common mistakes and always prioritize preserving the quality of your dish. Now, go enjoy your delicious, reheated Spam Musubi!
