Smoked Acorn Squash on a Pellet Grill at 350°F

Updated: October 30, 2026

Smoked acorn squash on a pellet grill makes a simple side dish with a short ingredient list: squash, olive oil, garlic, thyme, salt, and pepper. Cook it over indirect heat until the flesh gives easily under a fork. The base recipe needs no brown sugar or syrup.

Quick Answer: Halve and seed two small acorn squash. Brush the cut surfaces with seasoned olive oil, place cut-side up in a shallow metal pan, and cook over indirect heat at 350°F. Allow about 60–90 minutes, checking from 45 minutes. Remove each half when a fork slides easily into the thickest flesh; rest 5 minutes before serving.

Key Points

• Use two similarly sized squash so the halves cook at roughly the same rate.
• Keep the grill at 350°F with its indirect-heat parts installed.
• A shallow pan makes the halves easier to move and keeps oil off the drip system.
• Judge the finish by tenderness, with the cooking time as a planning estimate.

How Much Time Does This Recipe Take?

Plan on 15 minutes of preparation, 60–90 minutes of cooking, and a 5-minute rest, plus your grill’s startup time. Thick squash, cold weather, and a crowded grill can extend the cook. Check each half separately.

What Ingredients Do You Need?

You need acorn squash and a light coating of savory seasoned oil. The squash supplies its own sweetness; a little butter or lemon at the end is optional.

• 2 small acorn squash, about 1–1½ pounds each
• 2 tablespoons olive oil
• ½ teaspoon fine salt, or less to taste
• ½ teaspoon garlic powder
• ½ teaspoon dried thyme
• ¼ teaspoon ground black pepper
• Optional finish: 1 tablespoon unsalted butter, divided among the four halves
• Optional finish: a little lemon juice and chopped parsley

Choose firm squash with sound skin and no soft spots. Keep the two close in size. One oversized squash and one tiny squash make the timing unnecessarily awkward.

Which Pellets Work Well With Acorn Squash?

Apple, cherry, or a mild blend are easy starting points. Use clean, dry cooking pellets. A mesquite blend gives a stronger flavor if that is what you enjoy.

At 350°F, expect the wood-fired flavor to be lighter than it would be during a long, low-temperature smoke. There is no need to add a smoke tube for this recipe. If the pellet supply has been sitting in damp weather, review how to store wood pellets and charcoal so they stay dry before starting.

How Do You Cook Smoked Acorn Squash on a Pellet Grill?

Prepare the halves, season the exposed flesh, and roast them uncovered over steady indirect heat until tender. This method adapts oven-roasting to the pellet grill; the 60–90-minute cooking range is an estimate for the squash size listed above.

Step 1: How Should You Prepare the Pellet Grill?

Start with a clean grill and preheat it to 350°F according to its manual. Check the firepot and grease system while the grill is cold. Fit the heat diffuser and drip tray correctly, and close any direct-flame searing opening.

Allow the grill to finish its normal startup before adding food. Keep the cooking setup indirect throughout this recipe.

Step 2: How Do You Cut the Squash Safely?

Wash and dry the squash, steady it on a nonslip cutting board, and halve it lengthwise. Trim a thin slice from an end if needed to create a stable base. Keep your fingers out of the blade’s path and avoid forcing the knife through the hard stem.

Use a spoon to remove the seeds and stringy center. If the squash is too hard to cut comfortably, buy prepared halves instead of wrestling with the knife. Leave the peel on to support the flesh during cooking.

Step 3: How Should You Season the Halves?

Mix the olive oil, salt, garlic powder, thyme, and pepper, then brush the mixture over the cut flesh and inside each cavity. Spread it evenly rather than leaving all the seasoning in the center.

Set the halves cut-side up in the shallow pan. Use a pan that fits without blocking the grill’s airflow. The halves should sit securely and have a little space between them.

Step 4: How Long Should the Squash Stay on the Grill?

Cook with the lid closed for roughly 60–90 minutes, beginning your tenderness checks at 45 minutes. Place the pan away from a known hot edge. Rotate it if one side is browning faster.

Open the lid only when you need to check or rotate. Remove any half that finishes early and continue cooking the others. A large, thick piece may take longer than the estimate.

Step 5: How Do You Know When Acorn Squash Is Done?

Push a fork or thin skewer into the thickest flesh near the outside of the cavity; it should slide in easily. The center should feel soft when scooped, without a firm, crunchy band beneath the surface.

Illinois Extension’s winter-squash preparation guidance uses fork or skewer tenderness to judge the finish and includes 350°F oven cooking. This recipe uses that tenderness check with indirect pellet-grill heat.

Step 6: How Should You Finish and Serve It?

Move the pan to a heatproof surface and rest the squash for about 5 minutes. Add the optional butter while the flesh is hot, or finish with a little lemon juice and parsley. Taste before adding more salt.

Serve a half with a spoon so each person can scoop out the flesh. The pan stays hot after it leaves the grill, so use dry heat-resistant gloves and keep it clear of the table edge.

Why Is the Squash Brown Outside but Still Firm Inside?

The outside is receiving more heat than the thick center can absorb. Move the pan away from the hot area, confirm the grill is near 350°F, and loosely tent the pan with foil while the flesh finishes softening.

Do not raise the grill sharply just because the timer has passed an hour. First check the actual tenderness and whether the pan is sitting in a cooler part of the cooker.

What Can You Serve With Smoked Acorn Squash?

Pork chops, chicken, and a simple green vegetable make easy partners for the savory squash. For another pellet-grill main course, see thick pork chops on a pellet grill.

Cook each dish at its own recommended setting and check its own doneness. If you want a fall dessert afterward, pellet grill apple crisp is another option. Its 375°F instructions and timing are separate from this 350°F squash recipe.

How Do You Store and Reheat Leftover Squash?

Refrigerate leftovers promptly in shallow covered containers and use them within 3–4 days. Follow USDA leftover-storage guidance: refrigerate at 40°F or below within 2 hours, or within 1 hour when the outdoor temperature exceeds 90°F.

For reheating, cover the squash in a shallow oven-safe dish with a small splash of water. Use an oven set to at least 325°F, or use a microwave. Check several places and heat the leftovers to 165°F, following USDA reheating guidance. Add any fresh herbs afterward.

Frequently Asked Questions

Can You Make Smoked Acorn Squash Without Brown Sugar?

Yes. The base recipe uses olive oil, garlic, thyme, salt, and pepper. Sugar and syrup are unnecessary for the savory version.

Should Acorn Squash Go Cut-Side Up or Down?

Use cut-side up for this method so the seasoned oil stays on the exposed flesh. Other roasting methods use cut-side down; follow one method consistently rather than swapping positions halfway through.

Should You Wrap the Squash in Foil?

Start uncovered. A loose foil tent is useful if the edges brown before the center becomes tender. Tight wrapping from the beginning produces a more enclosed, steamy cook.

Can You Double This Recipe?

Yes, if the grill has room for the pans without blocking airflow. Leave space around the halves and check them individually. Extra cold food and frequent lid opening can extend cooking time.

Final Verdict

Smoked acorn squash on a pellet grill is an uncomplicated fall side: season the halves, use indirect heat at 350°F, and give the thickest flesh time to soften. Keep the seasoning simple and let fork tenderness settle the finish.
