These sweet-and-spicy roasted pumpkin seeds are a crunchy, lightly caramelized, Cajun-seasoned snack made with fresh pumpkin seeds, avocado oil, and a touch of brown sugar. They're an easy oven-roasted fall snack with a medium heat, ready in about 45 minutes!
Hello, every Halloween, I used to feel bad throwing away the seeds after we carved our jack-o'-lanterns. So over the past couple of years, I've tried different ways to roast them. This one gives me the best texture and flavor, and it's the simplest.
I toss the seeds with salt and avocado oil, then roast them. Near the end, I sprinkle on a spoonful of brown sugar so it melts into a thin glaze. While they're still hot, I coat them with Cajun seasoning and cayenne.
The result is one of the easy, crunchy, spicy snacks. The shells turn light and crunchy, and the seeds inside taste nutty and toasted. Three things make it work: drying the seeds well, adding the sugar late so it doesn't burn, and adding the Cajun seasoning while they're hot.
No need to remove the shells. You can enjoy these roasted pumpkin seeds with the shells on!
Why You'll Love My Sweet and Spicy Pumpkin Seeds
- No more wasted pumpkin seeds. I use leftover seeds from our Halloween pumpkins to make a crunchy snack with just a few pantry ingredients.
- Sweet meets spicy. Brown sugar adds a light caramel sweetness that balances the savory Cajun spices and a pinch of cayenne.
- The roasting method matters. I've found that drying the seeds well, adding the sugar in the last few minutes, and roasting until they smell nutty gives me crispy shells and toasted seeds inside.
Ingredients & Substitutions
- Raw pumpkin seeds: I use the leftover seeds from carving our Halloween pumpkins, shells on. One medium pumpkin gives me about 1 cup. Seeds from sugar pumpkins work too.
- Avocado oil: Its mild flavor lets the spices shine and holds up well in the oven. Melted butter works if you like a buttery taste, but use any cooking oil to keep it vegan.
- Brown sugar: 1 tablespoon of packed light brown sugar gives a gentle sweetness that balances the heat. Use up to 2 tablespoons if you like them sweeter. Dark brown sugar adds a deeper molasses flavor, and coconut sugar works too.
- Cajun seasoning: I use McCormick Cajun seasoning. Brands vary in salt and heat, so taste yours first and adjust. Creole seasoning or Old Bay work too.
- Cayenne pepper: It's optional, for extra heat. I use ¼ teaspoon. If your Cajun seasoning is already spicy, start with a pinch.
How To Make Sweet & Spicy Roasted Pumpkin Seeds
- Step 1. Preheat your oven to 350°F. Cut the top off the pumpkin and scoop out the seeds and stringy pulp.
- Step 2. Put the seeds and pulp in the colander and rinse them. Pick out the seeds and pull off the strings.
- Step 3. Place the seeds in a single layer on a parchment-lined baking sheet.
- Step 4. Pat the seeds, and toss them with the salt and avocado oil until evenly coated.
- Step 5. Roast for 15 to 20 minutes, stirring every 10 minutes. Sprinkle the brown sugar over the seeds, toss to coat, and roast for 8 to 10 more minutes. Pull the pan as soon as the seeds smell nutty and toasty, even if the shells still look pale.
- Step 6. Tip the hot seeds into a bowl and toss them with the Cajun seasoning and cayenne while the sugar is still sticky. Spread them out and let them cool completely. The sugar sets as they cool, and that's when they turn crunchy. Break apart any clumps.
What I Learned Testing These Pumpkin Seeds
- Pick the pulp off by hand: Before rinsing, I pull the seeds away from the stringy pulp with my fingers. Use a colander to make the work easier.
- Trust the aroma, not the color: One time, I left a batch in for just 5 more minutes after that nutty smell filled my kitchen. The insides turned brown and bitter, but the shells still looked pale. Since then, I go by smell, not color.
- Add the sugar late: Brown sugar burns long before the seeds are done. Adding it for the last 8 to 10 minutes gives you a thin caramel glaze instead of a scorched, bitter coating.
- Season while they're hot: I add the Cajun seasoning the minute the seeds come out of the oven. The warm, sticky sugar grabs the spices, so every seed gets coated.
♨️Make Them Milder or Hotter
- Mild: Use ½ teaspoon of Cajun seasoning and skip the cayenne. The brown sugar keeps them sweet with just a gentle warmth.
- Medium: Follow the card with 1 to 1½ teaspoons of Cajun seasoning and ¼ teaspoon of cayenne. This is how I make them, with a warm kick that builds slowly.
- Hot: Use the full 1½ teaspoons, then add an extra pinch of cayenne. Taste one seed after it cools, then add more if you like.
How to Keep Them Crunchy For Longer
- Room temperature: Let the seeds cool completely, then store them in an airtight glass jar. They stay crunchy for up to a week. Sugar pulls in moisture from the air, so keep the lid tight.
- Fridge and freezer: Keep them in an airtight container in the fridge for up to 2 months. I haven't tried freezing these myself, but a freezer-safe bag should keep them for up to 3 months.
- Re-crisping: If the seeds lose their crunch, spread them on a baking sheet and warm them at 300°F for about 5 minutes. Pull them out as soon as you smell that nutty aroma so they don't over-toast.
Frequently Asked Questions
They roasted longer than they needed, or the brown sugar went in too early and scorched. In my experience, the insides turn brown and bitter even when the shells still look pale. Add the sugar for the last 8 to 10 minutes, and take the seeds out as soon as they smell nutty and toasty.
They may be undercooked or still warm. Let them cool completely first, since they get crispier as they cool. If they're still chewy, spread them on a baking sheet and warm them at 300°F for about 5 minutes, until they smell toasty again.
No. I've tried boiling them in salted water first, but it's an extra step, and this recipe gives the same result.
You can, but I prefer the oven. When I tried the air fryer, the fan blew the lighter, drier seeds around the basket. So I went back to this oven method.
📖 Recipe
Sweet and Spicy Roasted Pumpkin Seeds
Ingredients
For roasting
- 1 cup raw pumpkin seeds from 1 medium pumpkin
- 1 tablespoon avocado oil
- ½ teaspoon salt
For the glaze
- 1 tablespoon light brown sugar up to 2 tablespoons for sweeter seeds
For the spicy coating
- 1 to 1½ teaspoons Cajun seasoning
- ¼ teaspoon cayenne pepper Optional
Instructions
- Preheat the oven to 350°F. Cut the top off the pumpkin and scoop out the seeds and stringy pulp. Use colander, rinse them well, and remove any remaining strings.
- Drain the excess water. Spread them on a parchment-lined baking sheet and pat them as dry as possible. Add salt and avocado oil. Toss until evenly coated, then spread them into a single layer.
- Bake for 15 to 20 minutes, stirring every 10 minutes. Sprinkle the brown sugar over the seeds, toss, and bake for 8 to 10 more minutes. Remove them as soon as they smell nutty and toasted.
- Transfer the hot seeds to a bowl. Sprinkle with the Cajun seasoning and cayenne, and toss while the sugar is still sticky. Spread the seeds out and let them cool completely. They turn crisp as the sugar sets. Break apart any clumps.
Notes
- Dry the seeds well: Pat them dry with a kitchen towel before roasting. This helps the seeds turn crunchy.
- Add the sugar late: Brown sugar burns if it roasts the whole time. Add it only for the last 8 to 10 minutes.
- Watch for the aroma: Remove the seeds as soon as they smell nutty and toasted. Even 5 extra minutes can make the insides brown and bitter while the shells still look pale.
- Adjust the heat and sweetness: Use ½ teaspoon of Cajun seasoning and skip the cayenne for mild, or add an extra pinch of cayenne for hot. Use up to 2 tablespoons of brown sugar for sweeter seeds.
- Faster roasting option: Roast at 400°F for about 15 minutes, then add the brown sugar and roast for about 5 more minutes. Watch closely.
- Storage: Cool completely, then store in an airtight jar at room temperature for up to 1 week. Keep the lid tight, since sugar pulls in moisture.
- Timing: Prep 15 minutes; cook 25-30 minutes; total 40-45 minutes.
