How to Clean Walnuts

To clean walnuts before toasting, follow this process:

Step 1 – Soak walnuts in a large bowl

Put the walnuts into a large bowl and add enough water to cover them. The bowl needs to be large enough because the walnuts will swell up. Ensure that they are all submerged in water.

Step 2 – Cover the bowl and allow soaking for 4 to 8 hours

Use a clean kitchen towel to loosely cover the bowl, and leave the walnuts for 4 to 8 hours. Soaking removes dirt, tannins, and any residue on the walnut’s skin. It also rids them of the unpleasant astringent taste, improving the final flavor.

Step 3 – Rinse under cold water

Transfer the walnuts to a colander and rinse under cold water. Rinse until the water runs clear.

Step 4 – Drain excess water

Gently shake the colander to drain excess water from the walnuts. If you wish to eat them raw, you can leave them to dry. You can roast them in an oven, microwave, or stovetop to dry the excess water.

Do you need to toast walnuts before baking?

Step-by-step Process of Toasting Walnuts in a Microwave

Follow this guide when toasting walnuts in the microwave to get perfect results every time.

Step 1 – Soak and rinse the walnuts

Put walnuts in a large bowl and add enough water to cover them. Leave for 4 to 8 hours, and rinse in a colander under cold water until the water runs clear. This process removes tannins, as well as any dirt present. Washing walnuts before toasting them will rid them of the unpleasant astringent taste, and enhance the flavor. Most store brands come already cleaned, so you need to confirm this from the packaging.

Step 2 – Spread walnuts on a microwave-safe plate

Spread out the walnuts in a single layer on a microwave-safe plate. Do not crown or pile them on top of each other, to allow even toasting. Ensure that the plate you are using is microwave-safe by checking the safety information underneath. This will prevent serious accidents from occurring.

Step 3 – Lightly coat with melted butter/olive oil and seasonings (Optional)

Apply a light coat of melted butter or olive oil, and sprinkle some salt and seasonings such as black pepper on the walnuts. The coating helps salt and seasonings stick to the walnuts. Adding your favorite spices will make the flavor more exciting. This step is not necessary, but you can use it to improve the flavor.

Step 4 – Microwave on high heat for two minutes

Microwave the walnuts on the high heat setting for 2 minutes. Do not exceed 350 degrees Fahrenheit, because this can cause the walnuts to burn. Once they get heated for 2 minutes, take them out to prevent burning as well.

Step 5 – Stir and reheat at two-minute intervals

Stir the walnuts before reheating. Stirring is important for even temperature distribution, as microwaves tend to have hot and cold spots, making some walnuts get heated faster. To avoid an unpleasant situation where you have unequally toasted walnuts, stir them before reheating.

Microwave at two-minute intervals until the walnuts attain a darker, golden brown color, and become fragrant. This should take about four to eight minutes. Remember to stir at each break, so that they’re evenly done.

Tips for Toasting Walnuts in a Microwave

To avoid this mishap, keep the temperature at or below 350 degrees Fahrenheit. A kitchen thermometer can help you check this.
  • Microwave at intervals. Exposing walnuts to high heat for a prolonged time will cause them to burn. Therefore, it is crucial that you microwave at intervals, and keep stirring at each break to prevent this. This also corrects temperature differences caused by hot and cold spots in the microwave.
  • Use a microwave-safe plate. Safety should always be a priority when using the microwave because accidents are always waiting to happen. Confirm that the plate you are using is microwave safe by checking the safety information at the bottom of the plate. This assures you that the plate can handle the high temperatures in the microwave, without posing a fire risk or being a health hazard by exposing your food to toxic fumes.
  • Toast the nuts whole, then chop them up afterwards. If you would like chopped up walnuts, begin by toasting them whole, and then you can chop them up when they are done. Not only is it easier to chop up freshly toasted walnuts, but it also helps them toast more evenly when whole since it may be difficult to cut them into uniform pieces, making them unevenly toasted.
  • Don’t be afraid to spice up your walnuts. Experimenting with different herbs and spices will bring out a new and exciting flavor each time, which is different from just plain walnuts. Adding a little salt will also make them more palatable, o do not be afraid to try it.


Toasting walnuts in a microwave is a fast and convenient way to prepare them. It is mostly hands-free, and the process is quite easy to follow.

Toasting walnuts enhances the flavor and makes them crunchier and more fragrant, making toasted walnuts the ideal snack.
