How to Roast Pumpkin Seeds in the Oven

Measure 1 cup of cleaned pumpkin seeds after rinsing and blotting them dry. Divide the finished batch into 4 equal portions.

• Fresh whole pumpkin seeds (1 cup): Use the white, in-shell seeds taken from a pumpkin. Remove the pulp, rinse the seeds, and dry their surfaces before measuring.
• Olive oil (1 tablespoon): Toss the measured seeds well so the oil coats them without pooling on the pan.
• Fine sea salt (½ teaspoon / dry): Seasons the seeds evenly. Substitution: Fine table salt ➔ Use the same volume and toss thoroughly to distribute it.
• Garlic powder or smoked paprika (½ teaspoon, optional): Choose one for the basic savory batch, or leave both out.

Use a colander, clean towels, a bowl, and a rimmed baking sheet.

1. Heat the oven. Set it to 350°F (175°C) with a rack in the middle.
2. Clean the seeds. Pull the seeds away from the stringy pumpkin pulp. Rinse in a colander, rubbing off any fibers that cling to the shells.
3. Dry and measure. Dry the rinsed pumpkin seeds between clean kitchen towels, pressing gently to remove water. Spread them on a dry towel for 10–15 minutes, then check for visible droplets or wet patches underneath; blot again as needed before measuring 1 cup and adding oil. The 10–15 minutes is a check-in point, not a promise that the seeds are dry.
4. Season. Toss the measured seeds with 1 tablespoon olive oil and ½ teaspoon fine sea salt. Add ½ teaspoon garlic powder or smoked paprika if using. Toss until the coating looks even.
5. Spread and roast. Arrange the seeds in one layer on the baking sheet. Roast for about 15–25 minutes as a starting range. Stir after 10 minutes. From 15 minutes onward, check them often and cool a few before tasting.
6. Check for doneness. If pale seeds are still chewy after cooling, roast them for 2–3 minutes more and check again. Remove the pan when the seeds are lightly golden and the cooled samples are crisp. A thick shell may still feel firm to bite; do not keep roasting well-browned seeds just to soften the hull.
7. Cool. Leave the roasted seeds spread out on the pan until they are fully cool.

At 350°F, plan on about 15–25 minutes for cleaned, surface-dry whole seeds. This is a starting estimate, not a guaranteed finish time. Thick shells, wet patches, and differences between ovens can extend the time.

Checkpoint	What to do
After 10 minutes	Stir and spread the seeds out again.
From 15 minutes onward	Look for light browning. Cool a few seeds before tasting for crunch.
Pale and still chewy	Roast 2–3 minutes more, then check again.
Lightly golden and crisp after cooling	Remove the pan from the oven.

Check seeds from different parts of the pan. Larger shells may feel tough even when roasted. More oven time may burn well-browned seeds.

• Blot away surface water. Dry the shells between towels, then look underneath the seeds for wet spots before adding oil. A timer alone cannot tell you when they are dry.
• Give them room. Spread the seeds in one layer. A crowded pile traps moisture and browns unevenly.
• Taste after cooling. Hot seeds may seem softer than cooled ones. Let a few cool before deciding whether the batch needs another short roast.

Choose one seasoning variation per batch, replacing the optional garlic powder or smoked paprika. Use the salt amount listed for that variation instead of adding the base salt again. Each variation uses the same 1 cup of seeds and 1 tablespoon olive oil.

Variation	Use for one batch	When to add it
Garlic and paprika	¼ teaspoon garlic powder, ¼ teaspoon smoked paprika, and ½ teaspoon fine sea salt	Toss with the oil before roasting.
Cinnamon sugar	1 tablespoon sugar, ½ teaspoon cinnamon, and ⅛ teaspoon fine sea salt	Roast with the oil and salt. Toss the still-warm seeds with the cinnamon and sugar after roasting.
Cayenne and sea salt	⅛ teaspoon cayenne and ½ teaspoon fine sea salt	Toss with the oil before roasting.

Do not add extra oil for the sweet version. Watch the pan near the end of roasting.

Per-serving nutrition is unavailable because the roasted seed weight for this one-cup batch has not been measured. A cup of fresh seeds cannot be treated as the same weight as a cup of roasted seeds.

Whole roasted pumpkin seeds include the edible outer shells, which contribute fiber. A future estimate should include the recipe’s tablespoon of olive oil, divide the batch into four equal portions, and leave out optional seasonings. Net carbohydrates equal total carbohydrates minus dietary fiber.

Let fully roasted, dry seeds cool completely before putting them in an airtight container. A closed container keeps out moisture; closing it while the seeds are warm traps condensation and softens them. Keep a small batch in a cool, dry pantry and eat it while the flavor and crunch are good.

For longer storage, refrigerate the sealed container at 40°F (4°C) or below, or freeze it. Let frozen seeds warm inside the closed container before opening it to limit condensation. These steps do not promise a fixed storage life.

Discard seeds with visible mold or a rancid smell. Seeds that lose crunch are not necessarily spoiled, but smell and appearance alone cannot guarantee safety. These storage steps apply to fully roasted, dry seeds, not raw or damp ones.

Roast a small batch in one layer, then cool a few seeds before deciding if they are crisp. Serve them with Apple Peanut Butter Snack Boxes with Cinnamon Yogurt Dip or sprinkle them over Roasted Butternut Squash Soup with White Beans.
