How to Roast Kaddu Ke Beej: Exact Oven Temperature, Time and Portions
160°C. Fifteen minutes. One stir at the halfway mark. That’s the number that turns a tray of pale, chewy kaddu ke beej into crisp, nutty seeds, and it’s the number most online recipes get wrong by cranking the oven too hot.
Shell on or hulled? Decide first
When you scoop out a pumpkin for halwa or sabzi, the seeds you get are the whole seed: a flat, cream-coloured shell with a green kernel inside. Packets sold as “pumpkin seeds” in shops are usually the hulled green kernels, sometimes called pepitas. Some pumpkin varieties grow naturally shell-less seeds, but most kernels you buy have had the husk mechanically removed.
Both are edible. They behave very differently in the oven and in your mouth.
| Feature | Whole, in shell | Hulled green |
|---|---|---|
| Source | Your own pumpkin | Shop packet |
| Roast at | 160°C | 160°C |
| Roast time | 20 to 30 min | 10 to 15 min |
| Texture | Crunchy, fibrous | Crisp, puffed |
| Good for | Snacking | Salads, raita, laddoo |
The shell adds a lot of chewy fibre. Many adults like it and eat the whole seed; others crack them with their teeth like sunflower seeds and spit the husks. For small children and older people with dental trouble, hulled kernels are kinder.

Roasting seeds from your own pumpkin
A medium desi pumpkin of 2 to 3 kg gives about half to one cup of seeds. Cleaning them is the messy part, and it’s the step that decides whether they crisp or steam.
- Scoop the seeds and pulp into a large bowl of cold water. Squeeze the pulp strands with your fingers; the seeds float, the stringy pulp mostly sinks.
- Skim the seeds into a colander and rinse for 1 minute, picking off any remaining orange strings.
- Optional but worth it: boil the seeds for 10 minutes in 1 litre of water with 1 tablespoon salt. This seasons the inside and makes the shell crisper.
- Drain and spread on a clean kitchen towel. Pat dry and leave for at least 30 minutes, or overnight on a plate, until the surface feels dry to the touch.
- Preheat the oven to 160°C (145°C fan). Toss 100 g seeds with 1 teaspoon oil and 1/4 teaspoon salt if you didn’t boil them in brine.
- Spread in a single layer on a baking tray. Crowded seeds steam.
- Roast 20 to 30 minutes, stirring every 10 minutes. They’re done when the shells are golden, dry, and some start popping gently.
- Cool on the tray. They crisp further as they cool, so judge the crunch only after 10 minutes.
Roasting shop-bought hulled seeds
These are quicker and burn more easily because there’s no shell protecting the kernel.
- Preheat oven to 160°C (145°C fan).
- Spread 100 g hulled seeds on a tray. No need to wash.
- Roast 10 to 15 minutes, stirring once at 7 minutes.
- Listen: they’ll crackle and some will puff. Pull them when they smell toasty and a few are just turning light gold at the edges.
- Toss while warm with 1/2 teaspoon oil and your seasoning if you want spices to stick.
No oven? Use a tawa
Heat a heavy iron tawa or kadhai on low-medium. Add 100 g hulled seeds with no oil. Stir constantly for 5 to 7 minutes until they puff and pop. For whole shelled seeds, 10 to 12 minutes on low. Don’t walk away; a pan goes from perfect to scorched in under a minute.
Three desi seasonings
Chatpata: 1/4 tsp chaat masala, pinch of red chilli, few drops lemon. Haldi-kali mirch: 1/4 tsp haldi and 1/4 tsp crushed black pepper tossed in 1 tsp warm ghee. Ajwain-namak: 1/2 tsp lightly crushed ajwain and a pinch of kala namak. Each is for 100 g seeds.
How much is a sensible snack
Pumpkin seeds are dense. Around 30 g of hulled kernels is a sensible adult snack portion, roughly what fits in a cupped palm. That serving carries a fair amount of plant protein, magnesium, zinc and healthy fats, and it’s also substantial on calories, a bit over what’s in a small chapati with ghee. It’s easy to eat three times that from an open bag in front of the television.
A practical approach: roast a batch, then portion it into small steel katoris or zip bags right away, 30 g each. For children aged 5 to 12, half that is plenty. Stick with hulled kernels and seat them while eating.
For shell-on seeds, the weight includes husk, so a portion can be a little bigger, about 40 g, and you’ll naturally eat them slower.
In the desi kitchen and the old texts
Pumpkin-family kernels were one of the four kernels in char magaz, the classic Unani cooling mix. In that system they’re counted cool and moist, and hakeems paired them with milk or sharbat in summer. Village kitchens in Punjab and Uttar Pradesh rarely wasted pumpkin seeds: grandmothers dried them on a charpai in the sun, then roasted them in hot sand or ash for children to crack in the evenings. Ayurvedic cooking uses them in laddoos and as a light, nourishing snack. All of that is custom and heritage, not medical claim.
Myths, briefly
“Pumpkin seeds clear out worms.” A very old folk belief. If you or your child might have worms, see a doctor for proper medicine; seeds aren’t a substitute.
“Eating the shells is harmful.” Most healthy adults eat them without trouble, though large amounts of shells can cause a hard, uncomfortable stool. Chew well and drink water. The same fibre-needs-fluid rule applies, far more strictly, to isabgol.
“Roasting destroys all the goodness.” Gentle roasting at 160°C mostly changes flavour and texture. Very high heat and burnt seeds are a different story, which is one reason the low temperature matters.
Buying and storage
Good hulled kernels are deep olive green, plump and uniform. Greyish, shrivelled or yellowed kernels are old. Smell matters more than looks: fresh seeds smell mildly grassy, rancid ones smell like old oil or paint. Buy from shops with fast turnover and sealed dated packs.
Once roasted, cool completely before storing, or trapped steam turns them soft. Airtight glass jar, cupboard, up to 2 weeks. For longer, fridge up to 3 months. Raw hulled seeds keep 2 to 3 months in the cupboard and around 6 months in the fridge.
Choking: whole seeds and kernels are a choking risk for children under 4. Grind them into a powder for porridge or laddoo instead. Allergy: seed allergy happens; stop at any mouth itch, rash or lip swelling, and get emergency help for breathing trouble. Blood thinners and heavy supplements: normal food portions aren’t a known problem, but concentrated pumpkin seed oil capsules or extracts are different, so if you take regular medication, speak with your pharmacist before adding supplements. Salt: if you’ve been told to limit salt for blood pressure or kidney reasons, roast them unsalted. Digestive trouble: anyone with diverticular disease, bowel narrowing, or recent gut surgery should ask their doctor before eating shell-on seeds in quantity. Pregnancy: normal food amounts are fine for most, but skip supplement forms unless your midwife or doctor agrees.

Why are my roasted seeds chewy?
They weren’t dried enough before roasting, the tray was crowded, or you tasted them hot. Dry them 30 minutes, spread them out, and let them cool 10 minutes.
Can I use an air fryer?
Yes. 160°C for 8 to 12 minutes for hulled, 15 to 18 minutes for shell-on, shaking the basket every 4 minutes.
Do they need soaking before roasting?
No. Soaking is optional for easier digestion or grinding, but you must dry them completely afterwards.
Can I roast seeds from ghiya or lauki the same way?
Mature seeds from these gourds can be dried and roasted similarly, but they’re smaller, so check at 12 to 15 minutes. Discard any that taste very bitter.
How do I know they’ve gone bad?
A sharp, paint-like smell or bitter taste. Throw them out.
How many pumpkin seeds should I eat in a day?
About 30 g of hulled seeds, roughly a cupped palm or 3 level tablespoons, is a sensible adult snack. Children aged 5 to 12 need about half that. Portion them out after roasting so the bag doesn't vanish.
How long do roasted pumpkin seeds last?
Up to 2 weeks in an airtight jar in the cupboard, or about 3 months in the fridge. Cool them completely before storing or trapped steam makes them soft.
Can young children eat pumpkin seeds?
Whole seeds and kernels are a choking risk for children under 4. Grind them into a powder and stir it into porridge or laddoo instead.
