How to Dry Pumpkin Seeds

Many gardening enthusiasts enjoy harvesting pumpkin seeds from their backyard or community garden plots. This simple task yields seeds for the next growing season or provides a delicious, crunchy snack. Luckily, pumpkin seeds are one of the easiest crops to harvest due to their large size and the abundance of seeds in each pumpkin. However, you must properly clean and dry the seeds before either planting or roasting them.

Cut the pumpkin open to extract the seeds. Place the pumpkin upright on a flat surface. Using a large kitchen knife, insert the blade into the top of the pumpkin. Gradually press down, rocking the knife from side to side to widen the cut. Continue slicing down the entire length of the pumpkin. Once you’ve cut through half of the pumpkin, switch to the other half and repeat the same process.

• After slicing around the pumpkin, make a final cut through the entire pumpkin, then carefully separate the two halves with your hands.
• Hold the pumpkin firmly in your non-dominant hand. Be cautious, and never place your hand in front of the blade.

Scoop out the pumpkin seeds with a spoon. With a quick scooping motion, most of the seeds will easily come loose. For seeds that are harder to remove, use a spoon to scrape along the pumpkin's interior to release them. If you don't mind getting a little messy, you can use your hands to pick out any seeds that the spoon can't reach.

• If you have an ice cream scoop, you can use it to scrape along the pumpkin’s sides to extract the seeds.

Remove the pumpkin flesh stuck to the seeds. The easiest way to do this is by pulling the flesh off with your hands. If you’re drying the seeds for roasting and want extra flavor, it’s not necessary to remove all the pumpkin flesh. However, if you plan to save them for planting, it’s best to get rid of all the pulp.

• Soak the seeds in a bowl of water to help loosen the flesh and make it easier to peel off.

Wash the seeds in a colander with cold water. Place the colander in the sink and pour all the seeds into it. Turn on the cold water and let it run over the seeds while you gently swirl the colander to ensure all the seeds are rinsed. Then, place the colander back in the sink and use your hands to stir the seeds under the running water so that all sides of the seeds get wet.

• Pick off any remaining pumpkin flesh that’s still attached to the seeds.
• Don’t worry if the seeds seem slippery – they’re still clean, even if they feel a bit slick!

Pat the seeds dry with paper towels for 5-10 minutes. Lay 2-3 sheets of paper towel flat on a surface and pour the seeds onto them. Press another sheet of paper towel over the seeds to absorb the moisture. After 5-10 minutes, transfer the seeds into a clean bowl, being careful not to squeeze the paper towel.

• Make sure to remove any leftover pumpkin flesh or debris from the seeds.

Spread the pumpkin seeds on a baking sheet or tray. Pour the cleaned seeds onto the tray and spread them evenly in a single layer, making sure none of the seeds are touching or overlapping.

• If there isn’t enough room on the tray to spread the seeds in one layer, you will need to use multiple trays to dry them.

Dry the seeds in a cool, dry place for at least 1 month. Find a dry, non-humid location to dry the pumpkin seeds. An indoor area like a storage room or a shaded spot outside will work well for this purpose. Avoid areas with poor ventilation like garages, and never dry the seeds in a basement.

• Check the seeds daily and flip them to ensure both sides dry evenly.
• Do not pile the seeds on top of each other, as this will prevent them from drying properly and may cause mold to form.
• Air drying is the most effective and safe method, though it takes time.

Store the seeds in a paper bag or envelope until you're ready to plant or roast them. Place all the seeds in a paper envelope or bag and store them in a dry, cool place. If you can’t find an appropriate spot, you can keep them in the refrigerator.

• Be sure to remove any seeds that are moldy.

Arrange the seeds in a single layer on the dehydrator tray. Ensure the seeds are not stacked on top of each other. If your dehydrator tray has holes, you can cut a piece of parchment paper to fit the tray and place it underneath to prevent the seeds from falling through.

• Only dehydrate one tray at a time to ensure the seeds dry evenly.

Dry the pumpkin seeds at a temperature between 46-49°C for 1-2 hours. Set the dehydrator to 46-49°C. Stir the seeds every 20 minutes to ensure they dry evenly.

• Using a food dehydrator may cause more damage to the seeds compared to air drying, but it is still safer than oven drying.

Store pumpkin seeds in an envelope or paper bag in a cool, dry place. Avoid storing them in damp areas to prevent moisture from affecting the seeds. If you can’t find a suitable spot, you can store them in the fridge. Keep the seeds until you’re ready to roast or plant them.

• Remove any moldy seeds before storage.

Preheat the oven to the lowest temperature available. Most ovens have a minimum temperature of 93°C. If using an electric oven, you will typically need to wait 10-15 minutes for it to heat up. A gas oven will take about 5-10 minutes to preheat. Place the baking rack in the lowest position.

• For more accuracy, consider using an oven thermometer to monitor the temperature.

Dry the seeds in the oven for 3-4 hours. Spread the pumpkin seeds evenly on a baking tray, ensuring there’s no overlap. Place the rack in the lowest position in the oven and set the tray on top. Keep the oven temperature at the lowest setting—usually around 93°C—and wait for 3-4 hours.

• Stir the seeds every 20-30 minutes to prevent them from burning.
• If you plan to use the seeds for planting, be cautious not to let them burn or get scorched, as damaged seeds will not germinate.
• Drying seeds in the oven carries the highest risk, as there’s a greater chance of damaging the seeds.

Store dried seeds in an envelope or paper bag. Place all the dried pumpkin seeds in an envelope to keep them safe until you're ready to plant or roast them whenever you wish!

• Remove any moldy seeds before storage.
• Store the dried seeds in a dry, cool place. If you prefer, you can keep them in the fridge or freezer until planting season.
