How to roast acorn squash
Roasting acorn squash halves: Preheat your oven to 375 degrees and place the 4 acorn squash halves (seeds removed) open-side down on the baking sheet or skillet. Roast for about 20-30 minutes, or until the top of your squash feels tender when pierced with a fork. Set aside open side up after removing from oven to avoid over*steaming.
Caramelizing Onions: Start caramelizing the onions in a medium skillet. Set heat to medium high, add 1 tablespoon butter and cook stirring until deep golden brown, about 10 minutes. Add a little bit of water whenever onions start sticking to the pan to much. Remove onions onto a separate plate.
Sausage mixture: Add 1 tablespoon butter and minced garlic to the now empty skillet and cook until just tender, then add all the sausage and increase the heat to medium. Cook the sausage and stir to break up lumps, about 5-8 minutes until browned. Add the apples and herbs and continue to cook, stirring until the apples soften. Add the spinach and cook, stirring, until the spinach wilts. Salt and pepper the mixture, taste it and adjust seasoning.
Add the caramelized onions to the sausage mixture, leaving excess cooking fat in the pan.
Preheat your broiler and fill four halves of the squash with the stuffing mixture. Arrange the squash on the baking sheet, stuffing side up, and put under the broiler for 5 minutes until the tops get browned and crispy. Be careful not to over-burn. 5 minutes should be enough, but some broilers can be unpredictable.

- Roasting squash halves: Preheat your oven to 375 degrees and place the 4 acorn squash halves (seeds removed) open-side down on the baking sheet or skillet. Roast for about 20-30 minutes, or until the top of your squash feels tender when pierced with a fork. Set aside open side up after removing from oven to avoid over*steaming.

Made recipe exactly as written and it was fantastic. Thanks!
Sounds like you nailed it, Jessica!
I made this two nights ago, and it was so good. I made very few changes, I used veggie sausages, and melted some butter which I mixed with a little maple syrup and coated the squash interiors before turning them upside down to roast. It tastes like being out on a crisp, cold autumn evening, with the sticky sweet taste of the fairground still on your tongue. It’s become a huge yes in my family, and I want to thank you so much for sharing your recipe. I would never have dreamt up making something like this.
That was written quite beautifully! Thank you.
