Grilled Acorn Squash with Asiago and Sage

Fall brings a special bounty to the kitchen: winter squashes with deep flavors and hearty textures perfect for roasting and grilling. Among them, acorn squash stands out for its delicate sweetness and versatility. This recipe transforms simple acorn squash into a show-stopping side by leveraging the char and smoke from the grill, a touch of nutty Asiago cheese, and the woodsy perfume of fresh sage. The result is a dish that’s both rustic and refined—a celebration of autumn on your plate.

Why Acorn Squash Shines on the Grill

Acorn squash is uniquely suited for grilling. Its flesh caramelizes beautifully over direct heat, picking up smoky notes and developing soft, crisped edges. The signature ridges make for eye-catching grill marks, and its naturally mild flavor is a perfect canvas for bold pairings.

  • Seasonal availability: Acorn squash comes into season as temperatures drop, making it the ideal fall vegetable.
  • Texture contrast: Grilling brings a pleasing bite and tender interior.
  • Flavor flexibility: Its subtle sweetness pairs easily with savory, salty, and even herbal toppings.

How to Grill Acorn Squash: Step-by-Step Instructions

1. Choose and Prepare the Squash

Pick a medium acorn squash that feels heavy for its size and has firm, unblemished skin. Wash it thoroughly before slicing.

  • Slice in half: Use a sharp chef’s knife to cut the squash in half from stem to tip.
  • Scoop out seeds: Remove the seeds and stringy pulp using a spoon. (Tip: Save the seeds to roast separately!)
  • Cut into wedges: Slice each half into 1- to 1.5-inch-thick wedges for optimal grill surface.

2. Season the Squash

  • Drizzle with olive oil: Coat all sides to prevent sticking and encourage even browning.
  • Sprinkle with salt and pepper: Be generous; the squash’s mildness can handle it.
  • Add chopped sage: Reserve some for garnish.

3. Preheat and Set Up the Grill

  • If using a charcoal grill, bank coals to one side for indirect heat.
  • For a gas grill, heat to medium-high (about 400°F).
  • Clean and oil the grates just before grilling to minimize sticking.

4. Grill the Squash

  • Place slices cut side down: Position the wedges perpendicular to the grates for striking grill marks.
  • Grill over direct heat: Cook for 4–5 minutes per side, turning as needed, until deeply marked and almost tender.
  • Move to indirect heat: Finish cooking with lid closed until the squash is creamy and fully cooked, another 6–8 minutes. Test with a fork.

5. Finish and Serve

  • While hot, shower with grated Asiago cheese so it melts slightly over the squash wedges.
  • Top with fresh sage leaves (whole or slivered).
  • Serve immediately as a side or vegetarian centerpiece.

Expert Tips for Perfect Grilled Acorn Squash

  • Uniform wedges ensure even cooking.
  • Don’t peel the squash: The skin becomes tender and helps the wedges keep their shape.
  • Monitor heat: Squash can burn quickly, so use indirect heat to finish cooking if needed.
  • For deeper flavor: Add a pinch of smoked paprika or a sprinkle of chili flakes before grilling.
  • Grill pan alternative: Indoors? Use a cast iron grill pan over medium-high heat. Cook as described above, adjusting cook time as needed.

Serving Suggestions: Pairings and Variations

The nutty, aromatic flavors of grilled acorn squash with Asiago and sage make it a companion to many main dishes. Its creamy texture and savory notes are ideal for:

  • Grilled meats: Chicken, pork chops, or steak.
  • Pasta dishes: Especially those with brown butter or sage sauces.
  • Vegetarian feasts: Pair with lentil or grain salads, or as a main with a hearty pilaf.
  • Holiday spreads: Makes a stunning addition to Thanksgiving or any fall celebration menu.

Want to change it up? Try these easy variations:

  • Add a drizzle of maple syrup or honey for a sweet-savory contrast.
  • Swap the cheese: Use crumbled feta or goat cheese for tang.
  • Try different herbs: Thyme, rosemary, or parsley instead of sage.
  • Add nuts: Toasted pecans or walnuts for crunch and richness.

FAQ: Grilled Acorn Squash

Can I use other types of squash?

Yes! Butternut, delicata, or kabocha squash all grill beautifully and offer slightly different flavors and textures.

What can I serve with grilled acorn squash?

This dish pairs well with roasted meats, vegetarian grain bowls, grilled steaks, or as part of a harvest spread.

How do I tell when the squash is done?

The flesh should be tender when pierced with a fork but should hold its shape well enough to transfer from grill to platter. Avoid overcooking, as squash can become mushy.

Can I prepare the squash ahead of time?

You can slice and season the squash up to 1 day ahead. Grill just before serving for best flavor and texture.

Is acorn squash skin edible?

Yes—the skin softens on the grill and is entirely edible, though you can peel it if you prefer.

Tips for Success and Troubleshooting

  • Keep slices consistent: Uneven slices may cook at different rates.
  • Use a grill basket if your wedges are smaller or you want to prevent pieces from sticking.
  • If using a grill pan: Press gently on wedges with a spatula to promote caramelization and grill marks.
  • Watch the cheese: Add the Asiago just as the squash comes off the grill to avoid burning or clumping.
