If you’ve ever wondered what to do with all those seeds after slicing open a juicy watermelon, this post will walk you through the whole process step by step.
In this post, we’ll cover why processing watermelon seeds is worth the effort, the different ways to process watermelon seeds, and tips for storing them properly.
Let’s dive in.
Why Processing Watermelon Seeds Is Worth It
Processing watermelon seeds is worth it because those little seeds are packed with nutrients and have multiple uses.
Here’s why you should consider processing watermelon seeds instead of tossing them.
1. They’re Packed With Nutrients
Watermelon seeds are rich in protein, healthy fats, magnesium, and zinc.
When you process watermelon seeds properly, you preserve all those nutrients for your body to enjoy.
Roasting or drying them doesn’t strip away the good stuff, it just makes them easier to eat.
2. You Can Grow Your Own Watermelons
If you process watermelon seeds for planting, you can grow your own watermelons next season.
Learning how to process watermelon seeds for planting means you’ll never have to buy seeds from a store again.
Just make sure you’re using seeds from a ripe, healthy watermelon for the best results.
3. It Reduces Waste
Processing watermelon seeds is a great way to reduce kitchen waste.
Instead of throwing away a perfectly useful part of the fruit, you’re turning it into something valuable.
And that’s always a win in my book.
How to Process Watermelon Seeds Step by Step
Now let’s get into the actual process of how to process watermelon seeds.
The method you choose depends on whether you want to eat them or plant them.
1. Collect and Rinse the Seeds
Start by scooping out the seeds along with the flesh of the watermelon.
Place them in a colander and rinse under cool running water.
Gently rub the seeds to remove any stuck-on pulp.
When you process watermelon seeds, this washing step is crucial because leftover pulp can cause mold during drying.
2. Separate the Seeds from the Pulp
After rinsing, pick out any remaining pulp or stringy bits.
You can do this by hand or let the seeds soak in a bowl of water.
Healthy seeds will sink to the bottom while the pulp and empty seeds float.
This makes it easy to process watermelon seeds quickly and efficiently.
3. Dry the Seeds Completely
Spread the clean seeds in a single layer on a paper towel or baking sheet.
Let them air dry for at least 24 to 48 hours.
If you’re processing watermelon seeds for planting, they need to be bone dry before storage.
Any moisture left behind can cause them to rot or grow mold.
4. Roast the Seeds for Eating
If you want to eat your watermelon seeds, roasting is the way to go.
Preheat your oven to 325°F (160°C).
Spread the dried seeds on a baking sheet and drizzle with a little olive oil.
Sprinkle with salt or your favorite seasonings.
Roast for about 15 to 20 minutes, stirring halfway through.
When you process watermelon seeds this way, they come out crunchy and delicious.
5. Shell or Leave Them Whole
You can eat watermelon seeds whole, shell and all.
But if you prefer just the kernels, you’ll need to crack the outer shell.
The easiest way is to use a nutcracker or gently press them with the back of a spoon.
Some people process watermelon seeds by soaking them first to make shelling easier.
Processing Watermelon Seeds for Planting
If your goal is growing watermelons, you’ll want to process watermelon seeds differently.
Here’s how to do it right.
1. Choose Seeds from Heirloom Varieties
Heirloom watermelons produce seeds that grow true to the parent plant.
Hybrid seeds may not grow into the same watermelon you enjoyed.
So when you process watermelon seeds for planting, pick seeds from heirloom varieties whenever possible.
2. Ferment the Seeds
Fermenting helps remove the gelatinous coating around each seed.
Place the seeds in a jar with a little water and let them sit for 2 to 4 days.
Stir daily and watch for mold to form on top.
Once fermentation is done, rinse the seeds thoroughly.
This step is important when you process watermelon seeds for planting because it improves germination rates.
3. Dry and Store
After fermenting and rinsing, spread the seeds out to dry for at least a week.
Store them in a cool, dark, dry place in an airtight container.
Label them with the variety and date so you know what you’re planting next season.
When you process watermelon seeds this way, they can stay viable for years.
So, How Do You Process Watermelon Seeds?
You can process watermelon seeds by washing, drying, and then roasting them for eating or fermenting them for planting.
Whether you’re snacking or gardening, learning how to process watermelon seeds saves money and reduces waste.
Just remember to dry them completely before storing, and don’t skip the fermentation step if you plan to plant them.
Now you know exactly how to process watermelon seeds, so go grab that watermelon and get started.
