Ingredients
- Acorn squash — look for a squash that feels heavy for its size with a firm dark green skin. Avoid any with soft spots or cracks
- Olive oil — brushed on first to prevent sticking and help the squash develop color on the grill
- Maple syrup — adds natural sweetness and helps the glaze caramelize beautifully. Use pure maple syrup for the best flavor — not pancake syrup
- Butter, melted — combined with the maple syrup and cinnamon to make the glaze. Coconut oil works as a dairy-free substitute
- Cinnamon — adds warmth and depth to the glaze that pairs perfectly with the natural sweetness of the squash
- Salt and pepper — a light seasoning before grilling that balances the sweetness of the glaze
How to Make Grilled Acorn Squash
The key to perfectly grilled acorn squash is even slices and multiple passes of the maple cinnamon butter glaze — each layer builds flavor and caramelization. Here is how it comes together:
Step 1 – Preheat the grill to 350°F.
Step 2 – Cut 1 acorn squash in half and scoop out the seeds. Slice into 1/2-inch-thick wedges.
Step 3 – In a small bowl, whisk together 1 tablespoon maple syrup, 2 tablespoons melted butter, and ½ teaspoon cinnamon. Set aside.
Step 4 – Brush both sides of the squash slices with 1 tablespoon olive oil, then season lightly with salt and pepper. Place the squash on the grill and cook for 3 minutes.
Step 5 – Flip and brush generously with the maple cinnamon butter mixture. Grill for another 3 minutes, brushing again with the maple butter mixture.
Step 6 – If the squash slices are thick, continue grilling for an additional 2–3 minutes per side, or until fork-tender.
Step 7 – Brush once more with the maple cinnamon butter just before serving. Serve warm.
Tips for Success
- Cut evenly. Keeping the slices the same thickness ensures everything cooks at the same rate and caramelizes together. A sharp knife makes this much easier
- Oil the grill grates before cooking. The maple syrup caramelizes quickly and can stick. Lightly oiling the grates prevents the squash from tearing when you flip
- Watch for flare-ups. The butter and maple syrup can cause flare-ups on the grill. If this happens move the squash to indirect heat until the flame dies down then return to direct heat to finish
- Apply the glaze in layers. Brushing multiple times rather than all at once builds up a deeper caramelized coating on each side. Do not skip the final brush right before serving
- Do not overcook. The squash should be fork-tender but still holding its shape. Overcooked acorn squash turns mushy and falls apart on the plate — check it with a fork in the last few minutes
Variations and Substitutions
- Swap maple syrup for honey for a slightly different sweetness
- Add a pinch of cayenne to the glaze for a sweet and spicy combination
- Use coconut oil instead of butter for a dairy-free version
- Add a squeeze of fresh orange juice to the glaze for a bright citrus note
- Swap acorn squash for butternut squash or delicata squash — both work beautifully on the grill
- Finish with a sprinkle of chopped pecans or walnuts right before serving for added crunch
Serving Recommendations
- Grilled Chicken — the sweet caramelized squash pairs beautifully with simply seasoned grilled chicken
- Grilled Pork Chops — sweet and savory on the same plate — a combination that never gets old
- Grilled Steak — the maple cinnamon glaze is a surprising and delicious contrast to a bold seasoned steak
- Grilled Salmon — a light healthy pairing that fits perfectly into a clean eating summer menu
Storage and Freezer Instructions
Refrigerator
- Store leftover grilled acorn squash in an airtight container for up to 3 days
Freezer
- Grilled acorn squash does not freeze well — the texture becomes watery when thawed. Make only what you plan to eat fresh
Reheating
- Reheat on the grill over medium heat for 2–3 minutes per side or in the air fryer at 375°F for 3–4 minutes to restore the caramelized edges. Avoid the microwave as it makes the squash soft and watery
FAQs
No — the skin of acorn squash is edible and holds the wedge together on the grill. After grilling the flesh is easy to scoop away from the skin if you prefer not to eat it. Leaving the skin on makes prep significantly faster.
Two things prevent sticking — brush the squash with olive oil before grilling and lightly oil the grill grates before adding the squash. The maple syrup in the glaze caramelizes quickly so oiled grates are especially important for this recipe.
Pierce the thickest part with a fork — it should go through easily with no resistance. The edges should be slightly caramelized and golden. Total grill time is usually 12–15 minutes depending on the thickness of the slices.
Yes — preheat the Blackstone to medium heat and cook the same way. The flat surface gives you excellent caramelization on both sides and makes flipping easier than grill grates. Watch the maple butter glaze closely as it can brown faster on the flat top.
Acorn squash has a mild naturally sweet flavor with a slightly nutty undertone — similar to butternut squash but more subtle. The maple cinnamon butter glaze enhances that natural sweetness and adds a warm caramelized depth that makes it irresistible even for people who do not usually love squash.
