    With fall comes a bounty of root vegetables, tomatoes and squashes and you're left wondering how to preserve them and what to do with all of that harvest! Let's not forget about the seeds; there is no need to discard them.

    Normally we think of pumpkin seeds when it comes to roasting, but butternut squash seeds also make a great snack.

    I will also give you some tips on how to store the seeds after drying or roasting them. If you want to get more adventurous, you could even try making a plant-based milk like I do in my pumpkin seed milk recipe. (You can check out the post here: how to make pumpkin seed milk.)

    I also have tutorials for how to freeze cherries, how to cut a cantaloupe melon and how to make tomatillo salsa that come in handy this time of year.

    How to Save Butternut Squash Seeds for Planting

    It's a good habit to start saving seeds for planting rather than buy them again year after year. It can save you money and you will have acquired a new skill that you can pass down to your children or share with friends. Check out the easy steps below.

    Besides the cleaned seeds (following the steps above), you will also need paper towel, a baking sheet and an envelope.

    Step 1: Spread Seeds Out on Paper Towel. After you've cleaned the butternut squash seeds, spread the clean seeds out on a paper towel-lined baking sheet in a single layer. This way they will dry more efficiently.

    How to Roast Butternut Squash Seeds

    Ingredients

    Roasted butternut squash seeds ingredients labeled.
    • brown sugar - Can use light brown sugar or dark brown sugar for a deeper molasses flavor.
    • soy sauce - Light soy sauce is all you need. It's the kind you will most commonly find in the grocery store and most kitchens will have this type on hand.
    • lime juice - Freshly squeezed is best.
    • olive oil - Since we are roasting you don't need to waste money on a fancy bottle of extra virgin olive oil. Pure olive oil will do.
    • garlic powder - Adds a savory, umami flavor to the seeds, that is complementary to the sweetness of the brown sugar.
    • cleaned butternut squash seeds - You might need more than 1 butternut squash to get 1 cup of seeds.

    *Check recipe card for ingredient amounts.

    ๐Ÿ‘ฉ๐Ÿปโ€๐ŸณChef's Note: If you aren't keen on this sweet and savory flavor combination, you can also roast them plain or with olive oil and salt, using the same method.

    Step 1: Combine the Coating Ingredients. Preheat oven to 300ยฐF. Line a baking sheet with parchment paper. Mix the brown sugar, soy sauce, lime juice, olive oil and garlic powder together in a bowl.
