To roast pumpkin seeds, rinse them, dry them completely, toss with 1 tablespoon of oil and a pinch of salt per cup, then roast on a single layer at 300°F (150°C) for 20 to 30 minutes, stirring every 10 minutes. Let them cool fully so they crisp up. Dry seeds and a moderate oven are what keep them crunchy instead of chewy.
That’s the short answer. Below you’ll find the full step-by-step method, fixes for soggy seeds, flavor ideas for every kind of cook, and answers to the questions people ask most.

What You Need to Roast Pumpkin Seeds
- Raw pumpkin seeds from one pumpkin (about 1–2 cups)
- 1–2 tablespoons olive oil, avocado oil, or melted butter
- 1/2–1 teaspoon fine salt
- A bowl, colander, clean kitchen towel, and rimmed baking sheet
- Parchment paper (optional, for easy cleanup)
How to Roast Pumpkin Seeds: Step by Step
- Separate the seeds from the pulp. Scoop the pumpkin’s insides into a bowl of cold water. The seeds float, so skim them off and pull away large strands. A little clinging pulp caramelizes in the oven and adds flavor.
- Rinse well. Rub the seeds under cold running water in a colander until the slime is gone.
- Simmer in salted water (optional). Boil the seeds for 5–10 minutes in water with about 1 tablespoon of salt per 2 cups. This seasons them through and softens the shells.
- Dry completely. Pat the seeds dry, then spread them on a towel for 20–30 minutes, or overnight. This is the most important step, because wet seeds steam instead of roast.
- Oil and season. Preheat the oven to 300°F (150°C). Toss the dry seeds with oil and salt until lightly and evenly coated.
- Roast low and slow. Spread the seeds in a single layer on a lined baking sheet. Roast 20–30 minutes, stirring every 10 minutes, until golden and fragrant. Large carving-pumpkin seeds can take up to 45 minutes.
- Cool completely. Let the seeds sit on the pan for at least 10 minutes. They keep crisping as they cool, so test one only after it’s cool: it should snap.
Why Are My Roasted Pumpkin Seeds Soggy or Chewy?
Soggy or chewy seeds almost always mean the seeds were still damp when they went into the oven, or the pan was overcrowded. Here are the common problems and fixes.
| Problem | Likely cause | Fix |
|---|---|---|
| Soggy or chewy | Seeds not dry; crowded pan | Dry longer; spread in one layer; re-roast 10–15 minutes at 300°F |
| Burnt outside, tough inside | Oven too hot | Lower to 300°F and extend the time |
| Seasoning falls off | Seeds too dry or too little oil | Toss with oil first; add sugary coatings in the last 5 minutes |
| Shells too tough | Thick-hulled carving pumpkin | Simmer first, or crack and eat only the kernel |
Pumpkin Seed Flavor Ideas
Once you’ve mastered the basic method, try one of these. Add spices with the oil unless noted.
| Flavor | What to add | Best for |
|---|---|---|
| Classic salted | Olive oil and sea salt | Everyday snacking |
| Cinnamon sugar | Butter, 1 tbsp sugar, 1 tsp cinnamon, added in the last 5 minutes | Kids and family treats |
| Smoky and spicy | Smoked paprika, garlic powder, pinch of cayenne | Game day, cocktail snacks |
| Maple and sea salt | 1 tsp maple syrup and flaky salt, added in the last 5 minutes | Gourmet toppings |
| Za’atar or everything bagel | Olive oil and the seasoning blend | Salads, roasted vegetables |
Are Roasted Pumpkin Seeds Healthy?
Yes. Pumpkin seeds (called pepitas when hulled) are a good source of magnesium, zinc, iron, and plant-based protein, and in-shell seeds add fiber. They’re naturally gluten-free and dairy-free, so they suit most eating styles. Because they’re calorie-dense, a small handful is a typical snack serving.
Zero-Waste Pumpkin Cooking
Roasting the seeds turns a food scrap into a snack. To use the whole pumpkin, roast the flesh for soup or pie, simmer scraps into vegetable stock, and compost the shells and pulp. Store finished seeds in a reusable glass jar instead of a plastic bag. Roast seeds only from fresh pumpkins, not from decorations that have sat outside or held a candle.
Roasting Pumpkin Seeds With Kids (and Saving Some for Crafts)
Seed prep is a good job for small hands: scooping, rinsing, counting, and sorting. For crafters, set some seeds aside before roasting. Dried raw seeds can be glued into mosaics, painted for fall garlands, or used in sensory bins. Keep craft seeds away from toddlers, and don’t eat seeds that have been glued or painted.
How Long Do Roasted Pumpkin Seeds Last?
Once completely cool, roasted pumpkin seeds keep for about a week in an airtight container at room temperature. Refrigerate them for a few weeks, or freeze them for a few months. Their natural oils can turn rancid, so throw out seeds that smell off or taste bitter.
Frequently Asked Questions About Roasting Pumpkin Seeds
Do you have to boil pumpkin seeds before roasting?
No. Boiling is optional. Simmering for 5–10 minutes in salted water seasons the seeds and softens the shells, but well-dried seeds roast crisp without it.
What temperature is best for roasting pumpkin seeds?
300°F (150°C) works best. A moderate oven dries the seeds all the way through. Higher heat browns the outside before the inside dries, leaving a chewy center.
How long does it take to roast pumpkin seeds?
Expect 20–30 minutes at 300°F, stirring every 10 minutes. Large seeds from carving pumpkins can take up to 45 minutes. Start checking at 15 minutes.
Can you roast pumpkin seeds in an air fryer?
Yes. Air-fry dry, oiled seeds at about 300°F (150°C) for 10–15 minutes, shaking the basket halfway. Check early, since air fryers vary.
Can you eat pumpkin seed shells?
Yes. The shells are edible and add fiber. If you prefer a softer bite, simmer the seeds first or use hull-less (pepita) varieties.
Do you need to dry pumpkin seeds before roasting?
Yes. Dry seeds roast, while wet seeds steam. Pat them dry and let them air-dry for 20–30 minutes, or overnight, for the crunchiest result.
The Takeaway
Rinse well, dry thoroughly, roast low and slow at 300°F, and cool completely. Follow those four rules and you’ll have crisp, golden roasted pumpkin seeds that are healthy, budget-friendly, and nearly waste-free. Before your next pumpkin goes to the compost, save the seeds.
