Why Roast Pumpkin Seeds?

Roasting pumpkin seeds is a tradition that turns food scraps into healthy, delectable snacks packed with protein, fiber, and micronutrients. The process allows for creative flavoring, and with ingredients like honey mustard and thyme, roasted seeds offer gourmet appeal and crowd-pleasing crunch.

Ingredients

  • Pumpkin seeds (or winter squash seeds, any variety)
  • Olive oil
  • Kosher salt
  • Honey
  • Dijon mustard
  • Dried thyme (or fresh thyme, finely chopped)

Exact measurements may vary based on seed quantity and personal taste, but a typical starting point is:

IngredientStandard Amount (for 1 cup seeds)
Pumpkin seeds1 cup
Olive oil1 Tbsp
Kosher salt1/2 tsp
Honey2 tsp
Dijon mustard1 tsp
Thyme1/2 tsp

Step-by-Step Instructions

1. Harvest & Clean Seeds

  • Cut open the pumpkin and scoop out the seeds, separating as much pulp as possible.
  • An extra rinse is optional; a little clinging flesh adds flavor.
  • Pat the seeds dry with paper towels for best results.

2. Drying for Crunch

  • Spread cleaned seeds in a single layer on a baking sheet.
  • To achieve extra crispiness, use a preheating oven (250°F) with the fan on for 5 minutes, or let seeds air-dry for several hours.
  • Seeds should be completely dry before oiling, ensuring even roasting and superior texture.

3. Seasoning

  • Combine olive oil, honey, Dijon mustard, thyme, and salt in a mixing bowl.
  • Add seeds and toss until evenly coated—use a slotted spoon to avoid excess liquid.

4. Roasting

  • Preheat oven to 250°F (120°C).
  • Spread coated seeds on a parchment-lined baking sheet in a single layer.
  • Roast for 30-45 minutes (large pumpkin seeds), checking after 30 minutes for smaller varieties.
  • Increase oven temperature to 350°F (175°C) for a final 5-minute golden finish.
  • Allow seeds to cool—they will crisp up as they rest.

5. Storing

  • Let roasted seeds cool completely before storing.
  • Keep in an airtight container at room temperature for up to 1 week.
  • For longer-term snacking, refrigerate for up to a month.

Expert Tips for Perfect Crunchy Seeds

  • Dry thoroughly: Getting seeds as dry as possible before oiling and roasting is the secret to crackling crunch.
  • Low and slow roasting: Cooking seeds at 250°F prevents burning and lets spices and sugars caramelize gently.
  • Monitor sugar content: Honey causes seeds to brown faster. Check for doneness after 30 minutes.
  • Size matters: Smaller seeds (e.g. butternut squash) roast more quickly; adjust time accordingly.
  • Flavor layering: Tossing seeds with oil and flavor before roasting ensures a deep, infused taste—not just a surface coating.

Flavor Variations

Honey mustard and thyme aren’t the only options. Try these inventive twists:

  • Smoky & Spicy: Paprika, cayenne, and black pepper
  • Garlic Mustard: Mustard powder, garlic powder, onion powder
  • Curry: Curry powder, garam masala, coconut oil
  • Cinnamon Sugar: Cinnamon and brown sugar for a sweet treat
  • Classic Chex Mix: Seasoning salt, garlic powder, Worcestershire sauce

Troubleshooting & Common Mistakes

  • Soggy seeds: Caused by incomplete drying or overcrowded tray; spread seeds in a single layer and dry thoroughly before seasoning.
  • Burnt flavors: Oven temperature too high or over-roasting, especially with honey; reduce temperature if seeds brown too fast.
  • Lackluster flavor: Adjust seasoning ratios to taste and ensure all seeds are coated evenly.
  • Tough hulls: Some pumpkin varieties yield seeds with thicker shells; roast longer or choose smaller squash seeds for softer hulls.
