Quick Answer
To roast pumpkin seeds, scoop them out, rinse off the stringy pulp, and dry them thoroughly. Toss with about a teaspoon of oil and a pinch of salt per cup, spread in a single layer, and roast at 325 F for 20 to 30 minutes, stirring every 10 minutes, until golden and crisp.
The secret to crunch is dryness. Wet seeds steam instead of roast, which leaves them chewy.
For extra flavor all the way through, boil the seeds in salted water for 10 minutes before drying and roasting.
Step 1: Get the Seeds Out
Cut the top off your pumpkin or slice it in half, then scoop out the insides with a large metal spoon or an ice cream scoop.
Drop everything into a big bowl of water. The seeds float and the pulp sinks, so you can skim them off with your hands and pull away most of the strings in seconds.
A small pie pumpkin gives roughly a half cup to a cup of seeds. A large carving pumpkin can give two cups or more.
Step 2: Clean and Dry Them Well
Rinse the seeds in a colander until no orange strands remain. A few small bits are fine; they caramelize in the oven.
Now dry them. Spread the seeds on a clean kitchen towel and rub them gently, then leave them for at least 30 minutes, or overnight if you have time. You can also dry them in the oven at its lowest setting for 10 minutes before oiling.
I skip paper towels because the seeds stick to them. A lint free cotton towel works best.
Step 3 (Optional): Boil in Salted Water
Boiling is the step most people skip, and it is the one that makes the biggest difference. Simmer the cleaned seeds in salted water, about 2 tablespoons of salt per quart, for 10 minutes.
The salt seasons the inside of the shell, and the hot water helps the shell crisp more evenly. Drain and dry the seeds completely afterward, or they will not crisp.
Step 4: Season
For each cup of seeds, use about 1 teaspoon of oil or melted butter and 1/2 teaspoon of fine salt (use less if you boiled them). Olive oil, avocado oil, and melted butter all work.
Toss until every seed has a light sheen. Too much oil makes them greasy rather than crunchy.
Step 5: Roast Low and Slow
Heat the oven to 325 F. Spread the seeds in a single layer on a rimmed baking sheet lined with parchment. Crowded seeds steam, so use two pans if needed.
Roast 20 to 30 minutes, stirring every 10 minutes. They are done when they are golden brown, smell nutty, and you can hear them crackle when you shake the pan.
Small seeds from pie pumpkins finish faster than large carving pumpkin seeds. Start checking at 15 minutes.
Let them cool on the pan. Seeds crisp up even more as they cool, so do not judge doneness straight out of the oven.
Why Roast at 325 F Instead of Higher?
You can roast pumpkin seeds at 350 F or 400 F, and they will be ready faster. The problem is that the outside browns before the inside dries, so you get seeds that look done but chew like gum.
A moderate oven gives the seeds time to dry from the inside out. If you are in a hurry, 350 F for 12 to 18 minutes works, but watch closely.
Flavor Ideas
- Classic: Olive oil and sea salt.
- Garlic parmesan: Garlic powder, then finely grated parmesan tossed on in the last 5 minutes.
- Cinnamon sugar: Melted butter, cinnamon, and sugar. Add sugar in the last 10 minutes so it does not burn.
- Smoky: Smoked paprika, cumin, and a pinch of cayenne.
- Ranch: A spoonful of dry ranch seasoning mix.
- Everything bagel: Sprinkle the seasoning on right after roasting.
Add delicate dried herbs and anything sugary toward the end. Hardy spices like paprika and cumin can go on from the start.
Pumpkin Seeds vs Pepitas
Seeds from a typical carving pumpkin have a white hull you eat whole. Pepitas are the green, hull free seeds that come from certain pumpkin varieties, often called oilseed or naked seed pumpkins.
You can roast pepitas the same way, but they need only 8 to 12 minutes because there is no shell to dry out.
Are Roasted Pumpkin Seeds Healthy?
According to USDA FoodData Central, an ounce of shelled pumpkin seed kernels has roughly 160 calories, about 8 to 9 grams of protein, and is a good source of magnesium, zinc, and iron.
Whole seeds with the shell on add fiber. The main thing to watch is salt; seasoned seeds can get salty fast, so taste as you go.
How to Store Roasted Pumpkin Seeds
Cool them completely, then store in an airtight jar at room temperature for about a week, or in the refrigerator for up to two months. If they soften, a few minutes in a 300 F oven brings back the crunch.
Troubleshooting
Chewy seeds: They were not dry enough before roasting, or the pan was crowded. Return them to the oven for 5 to 10 minutes.
Burnt outside, raw inside: The oven was too hot. Drop to 325 F next time.
Seasoning will not stick: Use a little more oil, or toss the seeds with seasoning while they are still warm.
Frequently Asked Questions
Do I have to boil pumpkin seeds before roasting?
No, but it improves seasoning and crunch.
Can I roast seeds from other squash?
Yes. Butternut, acorn, and spaghetti squash seeds roast the same way, though they are smaller and finish faster.
Can you eat the shells?
Yes. Roasted carving pumpkin shells are edible and crunchy. If they feel too tough, try smaller seeds from pie pumpkins.
Can I use an air fryer?
Yes. Air fry at about 350 F for 8 to 12 minutes, shaking the basket every few minutes.
Bottom Line
Separate seeds in a bowl of water, dry them completely, use a light hand with oil and salt, and roast at 325 F until golden. Boil them first if you want them seasoned through. Do that and you will never end up with chewy pumpkin seeds again.
