It’s acorn squash season here in Utah and I couldn’t be happier about it. I think it’s the squash that gets overlooked a little bit though. Like, “It’s pretty but what do I do with it???” Ha! I’ve asked around lately and the biggest concerns I heard were that people just didn’t know how to cook it. Or that they just had never eaten it! This new recipe of mine for Italian Sausage & Mushroom Stuffed Acorn Squash is the most perfect fall dish and will seriously make you feel like a rock star in the kitchen.

I did not grow up eating acorn squash. Maybe they don’t grow in Texas? Or maybe Texans are too busy eating deep fried yellow squash to care? Funny, but probably true!
When I was dating my now husband, his mother made a simple roasted acorn squash with dinner. It was my first time ever having it and I was intrigued! She made hers with a classic butter and maple syrup glaze and I have been in love with these beautiful little squashes ever since. I’ve always made them the same classic way that I learned from my mother-in law. However, when I saw the huge mound of beautiful, local acorn squash for sale at Lee’s, I wanted to get creative. It started with Italian sausage and then I built the flavors from there. Let’s show you step-by-step how I made them!
Prepping the Acorn Squash
After washing and drying your acorn squash, cut them in half lengthwise.

Next, scoop out the seeds and stringy bits using a metal spoon.

After that, place them on a baking sheet lined with parchment paper or tin foil. If they do not lay flat then cut a small, flat notch on the back first.

Finally, brush with olive oil and sprinkle with salt and pepper. Turn over and lay them cut side down on the baking tray. Bake for 25 minutes at 400 degrees.

Make the Filling
This filling is DIVINE. Like I said earlier, I started with Italian sausage then built the flavors from there that I knew would go well. Onions, mushrooms, spinach, rosemary, and cranberries make the perfect filling for this then it’s topped with a buttery parmesan panko crust.



How to Serve Sausage Stuffed Acorn Squash
After 25 minutes of roasting, take the squash out of the oven, turn them over and add the stuffing. Top with the breadcrumb mixture then bake for 20 more minutes. Aren’t they pretty?

My Italian Sausage & Mushroom Stuffed Acorn Squash is the ideal fall side dish or can stand on its own as the main attraction. All you need is a side salad and some rolls and your meal is complete!

If you think you don’t like acorn squash, if you’ve never cooked with it, or if you love it already and need new ideas, THIS is your recipe to try. The mild, nutty flavor of the acorn squash pairs so perfectly with the bold flavors of the hearty filling. This dish is a must for the autumn months!

A must try! This looks easy and fancy all at once. Thanks for sharing!
We ate this last night. Wow! My family doesn’t eat mushrooms but we cut brown Cremini/brown Bella mushrooms very small to look more like meat. We only had one acorn squash so we used it and 2 delicata squash. It was so delicious!!! Thank you Charlotte!
So happy you and your family loved it! That’s a great idea for the mushrooms too!
I made this for dinner tonight but no where does it say when to add the rosemary?
Oh my goodness thanks for catching that mistake! I’ll get it fixed. You add the rosemary with the cranberries. I hope you liked it!
