Sausage Stuffed Acorn Squash

Last updated on October 22nd, 2025

This Sausage Stuffed Acorn Squash is the simplest cozy and delicious autumn meal. Roasted until perfectly tender and caramelized, the squash is filled with a cheesy, savoury mix of Italian sausage, onion, garlic, Parmigiano Reggiano and fresh thyme. 

I can think of nothing better than relaxing with a savoury meal roasting away in the oven when temperatures start to drop this time of year. So delicious simply roasted with olive oil, salt and pepper, sweet and buttery acorn squash is even better when stuffed with a delicious filling. 

Here’s everything you’ll need to make this Sausage Stuffed Acorn Squash

• 1 medium acorn squash, halved and seeded
• 1 tablespoon (15 grams) extra-virgin olive oil
• Coarse salt and freshly ground black pepper to taste
• ½ lb (250 grams) Italian sausage, casings removed
• 1 small yellow onion, chopped
• 2 cloves garlic, finely chopped
• 2 teaspoons balsamic vinegar of Modena
• 2-3 springs fresh thyme leaves
• 2/3 cup (65 grams) freshly grated Parmigiano Reggiano plus more for serving

A medium-sized acorn squash is ideal for a dinner for two and its slightly sweet, buttery flavour profile works well in this recipe. The balsamic vinegar adds a sweet and tangy umami flavour that complements the natural sweetness of the squash.  

Look for the bright orange or yellow patch on the side to be sure the squash was harvested at the right time and is ready to eat!

Variations & substitutions

Squash: If you don’t have acorn squash, you can use similarly sized spaghetti or kabocha squash. The cooking time may vary a little, but you’ll know they’re done once they’re tender and pierce easily with a fork.

Olive oil: Substitute butter for richer flavour.

Italian sausage: I like spicy fennel sausage.

Balsamic Vinegar: Miso or Worcestershire sauce would add similar depth of flavour.

Thyme: If you don’t have or prefer not to cook with thyme, substitute fresh sage or rosemary, both of which pair well with squash. 

Parmigiano Reggiano: Freshly grated Parmigiano Reggiano is best suited for roasting. Both feta and mozzarella would also work well here.

Tips for making Sausage Stuffed Acorn Squash 

To cut the squash: Holding the squash steady on its side with one hand, slice from top to bottom through the stem then scoop out all the seeds. 

Browning the sausage: Don’t overcook it, it will crisp up more in the oven.

Do I need to peel the squash? Not at all, all squash skin is edible once roasted.

Storage: Leftovers will keep well in the fridge for 3-4 days. To reheat, return to baking sheet and warm in the oven at 350ºF (177ºC) until heated through. 

Reserve squash seeds (washed and dried) for roasting with a little olive oil and coarse salt. They make a great topping for soups and salads!

This Sausage Stuffed Acorn Squash is a simple and delicious meal that requires very little prep time with the oven doing most of the heavy lifting. So much reward for so little effort!
