Butternut squash pumpkin takes on incredible depth when you roast it low and slow on the grill.
I’ve tested dozens of butternut pumpkin recipes over the years, and this method leads to the best caramelization without drying out the flesh.The char adds a smoky sweetness that pairs well with bold seasoning, and the texture comes out tender enough to eat straight from the shell with a spoon.
This roasted pumpkin butternut squash works as a standalone side or pairs well with any grilled protein. The prep takes less than 10 minutes, and the grill does the rest of the work.

Ingredients
Here’s what you need to whip up this butternut pumpkin recipe:
For the pumpkin spice blend:
- 2 tsp. ground cinnamon
- 1 tsp. ground ginger
- 1/2 tsp. ground nutmeg
- 1/4 tsp. ground cloves
- 1/4 tsp. ground allspice
For the roasted pumpkin squash:
- 1 large butternut squash (about 3 lbs.)
- 2 Tbsp. olive oil
- Salt and black pepper to taste
Directions
Follow these steps exactly, and you’ll end up with gorgeously roasted pumpkin squash:
Prep your grill and butternut squash pumpkin
Set your pellet grill to 350°F and let it warm up while you prep the squash.
Mix the cinnamon, ginger, nutmeg, cloves, and allspice in a small bowl. Set aside.
Use a sharp, clean knife to slice both ends off the butternut squash. Cut the squash in half lengthwise, then quarter each half. Use a tablespoon to scrape out the seeds and stringy pulp from each quarter.
(A sharp, clean knife makes quick work of the tough skin. Keep your knife maintained for safer, easier cutting.)Season the pumpkin butternut squash
Lightly coat the flesh side of each butternut squash quarter with olive oil. Season with salt and black pepper, then dust each piece generously with the pumpkin spice blend. Cover the entire surface.
Roast your butternut pumpkin
Place the quarters on the grill grates with the flesh side down. Let them cook for 45 minutes until the flesh starts to char and caramelize.
Flip each quarter so the flesh side faces up. Continue cooking for an additional 30 minutes, or until a fork can be inserted and pulled out cleanly without any resistance. Total cook time runs about 90 minutes, depending on the size of your squash and grill temperature.
The pumpkin butternut squash is done when the flesh probes tender and the edges show good caramelization.Serve your roasted pumpkin squash
Serve the quarters as is and let your guests eat straight from the shell with a spoon, or use a clean, sharp knife to cut the flesh away from the skin and cube it for plating.
Recipe Note
Chef’s Secrets for Killer Butternut Pumpkin Squash
Want your pumpkin squash to turn out perfect every time? Follow these tips:
- Pick the right squash. Look for butternut squash with tan skin and no soft spots. Smaller squash, around three pounds, cook more evenly than larger ones.
- Cut carefully. Butternut squash pumpkin has tough skin. Use your sharpest kitchen knife and a stable cutting board. Cut the ends first to create flat, stable surfaces before splitting lengthwise.
- Don’t skip the char. That first 45 minutes with the flesh side down creates caramelization that brings out the squash’s natural sugars. Resist the urge to flip early.
- Test doneness properly. The fork should slide in easily and pull out clean. If the flesh sticks to the fork, give it another 15 minutes.
- Store leftovers smart. Using a properly sharpened knife, cut any leftover pumpkin butternut squash into cubes and store in an airtight container for up to five days. Reheat in a skillet with a bit of butter.
This pumpkin squash recipe is a great example of what happens when you combine patient cooking with smart seasoning choices. At my last cookout, it disappeared faster than the main course. The quarters look impressive on the plate, and eating right from the shell feels rustic in the best way. Keep a sharp, clean knife ready for prep work, and take advantage of the long cook time to handle other dishes.
