Ingredients List

This recipe requires just a handful of pantry staples to create something truly special. Each ingredient plays a crucial role in developing the perfect texture and flavor profile.
- 2 cups fresh pumpkin seeds (from 1 large pumpkin)
- 3 tablespoons granulated sugar
- 1 tablespoon brown sugar (adds molasses depth)
- 2 teaspoons ground cinnamon
- 1/2 teaspoon vanilla extract
- 2 tablespoons melted butter or coconut oil
- 1/2 teaspoon salt

Timing
This recipe requires approximately 90 minutes from start to finish, which is 20% less time than traditional savory pumpkin seed recipes that often require longer soaking periods.
Preparation Time: 15 minutes for cleaning and seasoning seeds
Cooking Time: 25-30 minutes roasting time
Drying Time: 45 minutes for optimal texture
Total Time: 90 minutes
Step-by-Step Instructions

Step 1: Extract and Clean the Seeds
Cut open your pumpkin and scoop out all pulp and seeds using a large spoon or ice cream scoop. Separate seeds from the stringy pulp by hand, placing seeds in a large bowl.
Rinse seeds thoroughly under cold running water, rubbing them between your hands to remove all remaining pulp. This step is crucial for achieving maximum crispiness during roasting.
Step 2: Dry the Seeds
Pat seeds completely dry using paper towels or clean kitchen towels. Spread them on a baking sheet lined with paper towels and let air dry for 45 minutes.
Properly dried seeds will roast more evenly and develop better texture. Moisture is the enemy of crispiness, so don’t rush this step.
Step 3: Preheat and Prepare
Preheat your oven to 300°F (150°C). Line a large baking sheet with parchment paper for easy cleanup and to prevent sticking.
Lower temperatures ensure even cooking without burning the delicate sugar coating. Higher temperatures often result in bitter, overcooked exteriors with chewy centers.
Step 4: Create the Cinnamon Sugar Coating
In a large mixing bowl, combine melted butter, vanilla extract, and salt. Add the dried pumpkin seeds and toss until evenly coated.
In a separate small bowl, whisk together granulated sugar, brown sugar, cinnamon, and nutmeg. Sprinkle this mixture over the buttered seeds and toss thoroughly until every seed is coated.
Step 5: Roast to Perfection
Spread seasoned seeds in a single layer on the prepared baking sheet. Avoid overcrowding, which leads to uneven cooking and soggy results.
Roast for 25-30 minutes, stirring every 10 minutes to ensure even browning. Seeds are done when they’re golden brown and crispy when cooled for 2-3 minutes.

Common Mistakes to Avoid
Success with roasted pumpkin seeds depends on avoiding these frequent pitfalls that can turn your anticipated treat into a disappointing disaster.
- Insufficient Drying: Wet seeds create steam during roasting, resulting in chewy rather than crispy textures. Always allow adequate drying time.
- Overcrowding the Pan: Cramped seeds cook unevenly and steam each other. Use multiple baking sheets if necessary for proper spacing.
- Temperature Too High: Excessive heat burns the sugar coating before seeds cook through. Stick to 300°F for optimal results.
- Skipping the Stirring: Seeds need regular movement during roasting to prevent burning and ensure even caramelization of the sugar coating.
- Inadequate Seasoning Distribution: Uneven coating leads to bland bites mixed with overly sweet ones. Toss thoroughly at each step.
Storing Tips for the Recipe
Proper storage maintains the crispy texture and fresh flavor of your Cinnamon Sugar Roasted Pumpkin Seeds for maximum enjoyment over several days.
Short-term Storage: Store completely cooled seeds in an airtight container at room temperature for up to one week. Glass jars or sealed plastic containers work best for maintaining crispiness.
Humidity Control: Add a small packet of food-safe silica gel or a few grains of uncooked rice to absorb excess moisture and prevent sogginess.
Freezer Storage: For longer storage, freeze seeds in freezer-safe bags for up to three months. Thaw at room temperature and re-crisp in a 250°F oven for 5 minutes if needed.
Make-Ahead Tips: Clean and dry seeds up to 24 hours before roasting. Store dried, uncooked seeds in the refrigerator until ready to season and roast.
