Pumpkin Seeds Recipe Oven: Toasted Nutty Crunch in 20 Minutes

Turn those leftover pumpkin seeds into a crispy, nutty snack in under 20 minutes. This simple oven method transforms raw seeds into golden, crunchy bites with minimal effort.

Clean, dry, and season the seeds before roasting at high heat. The result is a perfectly toasted snack that’s salty, satisfying, and far better than store-bought.

Ingredients for Pumpkin Seeds Recipe Oven

Transform raw seeds into a crispy, nutty snack with these pantry staples and spices.

The seeds must be completely dry before roasting or they’ll steam instead of crisp. Fresh pumpkin seeds from a carved pumpkin work best—just separate them from the stringy bits and rinse well. For store-bought, Whole Foods or Trader Joe’s carry raw, unsalted seeds year-round. Look for plump, uniform seeds without hulls for even toasting.

No smoked paprika? Regular paprika plus a pinch of chipotle powder creates a similar effect. Don’t have cumin? Coriander at the same amount works, though the flavor profile shifts slightly. If avoiding heat, skip the cayenne entirely. The olive oil can be swapped for avocado or melted coconut oil without affecting texture.

Store cooled seeds in an airtight container at room temperature for up to 2 weeks. They’ll lose crispness faster in humid environments, so add a silica packet if storing long-term. Freezing isn’t recommended—it introduces moisture. Re-crisp in a 350°F oven for 5 minutes if they soften.

Step-by-Step Instructions for Roasted Pumpkin Seeds

Here’s the method. Straightforward, tested, works every time.

Step 1: Preheat Oven and Prepare Baking Sheet

Preheat your oven to 375°F. This high temperature ensures the seeds toast evenly and develop that deep, golden color without burning. Line a rimmed baking sheet with parchment paper to prevent sticking and make cleanup easier.

I always use parchment rather than foil—it allows better air circulation, which promotes even toasting. The parchment also prevents the extra-virgin olive oil from pooling, which could lead to uneven browning or soggy spots.

Step 2: Toss Seeds with Oil and Seasonings

In a large bowl, combine the 2 cups raw pumpkin seeds with the 1 tbsp extra-virgin olive oil. Toss thoroughly until every seed is evenly coated. The oil acts as a carrier for the seasonings and helps them adhere to the seeds.

Add the 1 tsp kosher salt, 0.5 tsp garlic powder, 0.5 tsp smoked paprika, 0.25 tsp ground cumin, 0.125 tsp cayenne pepper, 0.25 tsp dried thyme, 0.25 tsp onion powder, and 0.25 tsp black pepper. Toss again until the seeds are uniformly seasoned. The spices should cling to the seeds without any dry spots.

Step 3: Spread Seeds on Baking Sheet and Toast

Spread the seasoned seeds in a single layer on the prepared baking sheet. Avoid crowding—if the seeds overlap, they’ll steam rather than toast. You want each seed to have direct contact with the hot air for maximum crispiness.

Place the baking sheet on the middle rack of the preheated oven. Bake for 10 minutes, then stir the seeds to ensure even toasting. Return to the oven and bake for another 8-10 minutes, or until the seeds are golden brown and crisp. Watch closely during the last few minutes to prevent burning.

Step 4: Cool and Store

Remove the baking sheet from the oven and transfer the seeds to a wire rack or parchment paper to cool completely. They’ll continue to crisp up as they cool. Taste one and adjust the kosher salt if needed—sometimes a little extra enhances the flavors.

Once fully cooled, store the roasted pumpkin seeds in an airtight container at room temperature for up to 1 week. If they lose their crispness, you can revive them by spreading them on a baking sheet and reheating in a 350°F oven for 5 minutes.
