Raw Seeds Are Fine If You Like Chewing Bark
The simplest way is just cracking them open with your teeth and eating the kernel inside. Most people buy roasted already. If you are getting raw seeds straight from a pumpkin, there is a proper process if you want them palatable rather than bitter and slimy. Rinse them in a colander and pull off the fibrous strings. They look gross at this stage. This is normal. You roast them at 300°F for 20 to 30 minutes, stirring halfway through. Toss them in a thin coat of oil and salt before they go in. If you skip the oil they come out dried out and harsh on the jaw. That is my main point of contention with most guides online. They tell you to bake them dry like some kind of health food penance. That produces sad results. I learned that after burning three batches in 2019 trying to make something healthier. The oil does not ruin anything. It conducts heat evenly. The kernels are the part you actually eat. The shell is edible but most people spit it out. Shelled pumpkin seeds, called pepitas, are green and require no cracking. You can buy them pre-shelled or crush the shells yourself with a nutcracker or the heel of your palm. One thing people consistently mess up is temperature. Go over 350°F and the oils inside the kernel turn bitter within minutes. I have stared at a sheet of completely ruined seeds because I set the oven dial wrong and walked away. It took about eight minutes at that temperature before they started smoking slightly. Do not walk away.
If you want them salted, use fine sea salt. Kosher salt works too but the flakes sit on the surface and some pieces end up unbitten. Fine salt coats better. A quarter teaspoon per cup of seeds is enough. More than that and you are just eating salt. The nutritional benefit drops off a cliff when you are consuming more sodium than the seed itself provides. Storage matters more than people think. Roasted seeds go rancid faster than raw ones because the heat opens up the oils. Keep them in an airtight container at room temperature for about a week. In the fridge they last roughly a month. In the freezer they hold for three to four months without noticeable quality loss. I keep a half-cup portion in the freezer at all times. Grab it straight from the bag when I want something crunchy. No reheating needed. Some edge case people run into is moisture re-absorption after roasting. If you leave them cooling on the baking sheet they pull humidity from the air and turn chewy instead of crisp. Spread them on a wire rack for ten minutes after taking them out. That lets airflow hit both sides. It takes two extra minutes and makes a real difference in texture. I started doing this after my first batch sat on the pan and came out leathery. They were still edible. Just unpleasant.
The nutritional profile is decent. A standard ounce serving has around seven grams of protein, five grams of fiber, and a solid chunk of your daily magnesium and zinc. That is why people seek them out. But the magnesium content varies depending on soil quality where the pumpkin was grown. If you are eating them purely for supplementation you will not get consistent dosing. The zinc is more reliable. Still, they are not a replacement for actual dietary planning. They are a snack that happens to be nutritious. Treat them like one. One counter-intuitive thing: under-roasting is better than over-roasting. Seeds that look pale and slightly soft in the center are still fine to eat. Some people prefer that texture. The flavor is milder and the crunch is gentler. I actually prefer them slightly underdone myself. Over-roasted seeds taste nutty but also dusty, like they have been sitting in a pantry too long even though they came straight out of the oven. That is a texture problem, not a safety problem. If raw seeds are your thing, just wash them well and eat them. They are safe raw. Some cultures do this regularly. The bitterness from the shell is the main downside. Scraping the kernel out with your thumbnail works if you do not have tools. It is slower than using a cracker but it gets the job done without any cooking equipment.

Do not buy pre-shelled pepitas that have been sitting on a shelf for six months. The oils oxidize and you get a flat, cardboard taste that no amount of seasoning fixes. Check the packaging date. If there is none, buy from a store with high turnover. Online bulk bins are risky unless you know the rotation schedule. I stopped buying from one particular brand after noticing a consistent off-flavor across three separate purchases. Their shipping warehouse must sit on stock for a while before it reaches shelves. That is the whole thing. Roast low and slow with oil, cool on a rack, store in the freezer if you are not eating them within a week, and do not set your oven above 325°F unless you enjoy bitter seeds. Everything else is optional.
