How to Make Stuffed Acorn Squash
Stuffed acorn squash is easy to prepare and presents beautifully, but it does take about an hour start to finish, so leave this for weekends if you’re pressed for time. Fresh herbs are the key to making the stuffing really pop, so don’t substitute for dried if you can help it.
Roast the Acorn Squash
To prepare the squash for roasting, start by trimming each end. Place the squash on its side and using a sharp knife trim off the top just below the stem. Then slice about half an inch off the bottom. Be careful not to trim too much or you’ll have a hole in the bottom of your squash (like the one I did below!). Lastly, slice the squash through the center to create two halves.
Place the squash cut side up on the cutting board and scoop out the seeds using a spoon. Acorn squash have soft flesh, so they’re quite easy to de-seed.
Drizzle each squash with olive oil, then dust with salt and pepper. Place the squash flesh side down onto a parchment lined baking sheet and roast in a 400°F oven until the flesh is soft and the skin can be easily pierced with the tip of a knife. Total cooking time will depend on the size of your squash, but start with 30 minutes.
Make the Sausage and Vegetable Stuffing
While the squash is roasting you’ll make the stuffing. The stuffing preparation moves a little fast, so be sure to have your mise en place ready before you start (that’s just a fancy way of saying “have all your ingredients prepped and ready before you start cooking”).
Sautee a pound of mild italian sausage until it’s browned and cooked through. Break it up into small bits with a wooden spoon. Remove the sausage from the skillet with a slotted spoon, leaving the rendered fat behind.
Add the leeks and celery to the skillet and sautee until they’re soft and just starting to brown. Then add a little minced garlic, fresh sage and rosemary, and a handful of dried cranberries. Sautee that deliciousness together until the aroma is like woah.
Deglaze the skillet with a splash of red wine vinegar, then add a bunch of spinach and sautee until it’s just barely wilted. I used mature spinach because it’s heartier, but baby spinach works too.
Once the spinach has wilted, mix the contents of the skillet with the cooked sausage and stir it all together. Add some parmesan cheese if you want to rock the dairy train, or skip it to keep this paleo and dairy free.
Stuff and Reheat
By the time the stuffing is cooked, the squash should be ready. Remove it from the oven and flip over, being mindful of any steam that might escape.
Stuff each squash with a quarter of the sausage and vegetable stuffing. You’ll have quite a bit of stuffing, so go ahead and pile it on top pretty generously. Add the stuffed squash back to the oven and bake an additional 5 or so minutes, until the cheese has softened and the stuffing is bubbling.
These make an excellent meal all on their own, or with a tossed green side salad.
Dietary Accommodations and Variations
- Naturally gluten free and grain free
- Make it paleo by omitting the parmesan cheese. Be sure to use unsweetened dried cranberries.
- Use mature or baby spinach, or baby kale or swiss chard.
