How to Make or Prepare Pumpkin Seeds?
Preparing pumpkin seeds at home is simple and rewarding. Whether you want to enjoy them as a healthy snack or add them to meals, here’s how to do it the right way:
Step 1: Scoop Out the Seeds: Cut open a fresh pumpkin and use a spoon to scoop out the seeds along with the pulp.
Step 2: Separate Seeds from Pulp: Place the seed-and-pulp mixture in a bowl of water. Gently rub the seeds between your fingers to detach them from the stringy pulp. The seeds will float while most of the pulp sinks.
Step 3: Rinse the Seeds: Transfer the cleaned seeds to a strainer and rinse them thoroughly under cold water.
Step 4: Dry the Seeds: Spread the rinsed seeds on a clean kitchen towel or paper towel and pat them dry. Let them air-dry for a few hours or overnight for best roasting results.
Step 5: Season the Seeds (Optional): Place the dry seeds in a bowl. Add a drizzle of olive oil or melted butter and season with salt, garlic powder, paprika, cinnamon, or any seasoning of your choice.
Step 6: Roast the Seeds: Preheat your oven to 160°C (320°F). Spread the seasoned seeds on a baking tray in a single layer. Roast for 10–15 minutes, stirring once or twice for even toasting. Remove when golden and crisp.
Step 7: Cool and Store: Let the seeds cool completely before storing them in an airtight container. Keep in a cool, dry place or refrigerate for longer shelf life.
Optional Variations:
- Boil before roasting – Boil seeds in salted water for 10 minutes to improve texture and flavor.
- Raw prep – Skip roasting if you prefer to blend raw seeds into smoothies or grind them into seed butter.
Pumpkin seeds can also be soaked or sprouted if you want to reduce phytic acid and boost mineral absorption.
