Step-by-Step: How to Make Stuffed Acorn Squash

Ingredients

For the SquashFor the Filling
3 medium acorn squash2 tbsp olive oil
2 tbsp olive oil8 sage leaves, chopped
Salt & pepper1 lb ground Italian sausage
8 oz baby bella mushrooms, sliced
1/2 red onion, chopped
2 cloves garlic, finely chopped
1 tbsp fresh thyme, chopped (plus more for serving)
1/2 tsp salt
1/2 tsp black pepper, plus more for serving
1 1/2 cups cooked rice
1/3 cup heavy cream
1 cup grated fontina or Monterey Jack cheese

Preparation Steps

  1. Prep the Squash:
    • Preheat your oven to 400°F (200°C).
    • Slice each acorn squash in half lengthwise and scoop out seeds and stringy bits using a large spoon.
    • Rub the cut sides with olive oil and sprinkle generously with salt and pepper.
  2. Roast the Squash:
    • Arrange squash halves, cut-side down, on a parchment-lined or greased baking sheet.
    • Roast for 30–35 minutes until tender and golden at the edges.
    • After roasting, turn the squash halves over to expose the cut side up and continue roasting briefly if needed, until fully soft but holding their shape.
  3. Make the Filling:
    • While the squash is roasting, heat olive oil in a large skillet over medium heat.
    • Add chopped sage leaves; cook for 1 minute until fragrant.
    • Crumble in Italian sausage and cook until browned, breaking it up with a wooden spoon.
    • Add sliced mushrooms and cook until they release moisture and begin to brown.
    • Stir in chopped onion and cook until softened, followed by garlic, thyme, salt, and pepper.
    • Mix in the cooked rice and continue to cook until well combined and heated through.
    • Pour in heavy cream and sprinkle over grated cheese, stirring until the cheese melts and the mixture is creamy but thick.
  4. Stuff and Bake:
    • Fill each squash cavity generously with the hot sausage-mushroom mixture.
    • Arrange the filled halves back on the baking sheet and sprinkle extra cheese over the top if desired.
    • Bake for another 10–15 minutes until the tops are bubbly and golden.
    • Garnish with more fresh thyme and serve hot.

Pro Tips for Perfect Stuffed Acorn Squash

  • Don’t skip roasting cut-side down: Roasting the squash this way first helps the flesh cook evenly and allows for some caramelization.
  • Save the squash seeds: Clean and toast seeds with spices for a crunchy snack or a garnish!
  • Choose your grain: White, brown, or wild rice work well. Or substitute with farro or quinoa for variety.
  • Don’t overfill: The filling should be generous but not heaped, so it cooks evenly and doesn’t spill out.
  • Use a sharp, sturdy knife: Acorn squash are tough raw. Stabilize with a kitchen towel and use careful, firm pressure when halving.

Variations and Serving Suggestions

Alternative Fillings

  • Vegetarian version: Swap sausage for sautéed spinach, kale, or cooked lentils. Add more mushrooms and nuts for protein.
  • Cheese swap: Monterey Jack, Gruyère, or even goat cheese melt beautifully and offer unique flavor twists.
  • Dried fruits & nuts: A sprinkle of dried cranberries or toasted pecans adds texture and sweetness.
  • Change the herbs: Rosemary and parsley add bright, herby notes to the filling and garnish.

What Goes Well with Stuffed Acorn Squash?

  • Serve as a main dish with a simple green salad for a balanced, filling dinner.
  • Works as a hearty side for roasted meats, especially turkey or chicken at holiday gatherings.
  • Pair with roasted root vegetables or a crisp apple slaw for a cozy autumn spread.

FAQ: All About Acorn Squash and Stuffed Squash

How do you prep acorn squash for stuffing?

Acorn squash requires minimal prep. Cut each squash in half with a sharp knife, then scoop out seeds and stringy bits with a spoon. There is no need to peel the skin, as it becomes tender and edible when roasted.

Should acorn squash be baked cut-side up or down?

To ensure even cooking and a caramelized surface, roast acorn squash cut-side down initially. For the final bake with the filling, turn the halves cut-side up to finish cooking and melt the cheese.

How do you know when acorn squash is done?

Acorn squash should be completely tender all the way through before stuffing. Test with a fork—it should slide in easily. Once stuffed, the squash just needs to return to the oven long enough to heat the filling and melt the cheese.

Can you eat the skin of acorn squash?

Yes! The roasted skin of acorn squash is thin and tender, making it not only edible but also enjoyable. It helps the squash halves maintain their shape for stuffing.

What are other good fillings for acorn squash?

Any grain or protein filling works: try cooked greens (like spinach or kale), wild rice, lentils, or even cranberry and nut mixtures. Quinoa, chickpeas, and roasted vegetables are delicious options for vegetarian versions.

How many does this recipe serve?

Three medium acorn squash (halved) typically yield six servings as a main course or more as a side.

Quick Tips & Serving Ideas

  • Get ahead: Roast the squash and prepare the filling up to a day before, refrigerate separately, and bake just before serving.
  • To freeze: Stuffed squash halves freeze well—wrap tightly and freeze up to one month. Thaw and reheat in the oven.
  • Use leftovers: Extra stuffing can be baked in a small casserole dish or used in omelets, wraps, or as a base for stuffed peppers.
