Roasted Acorn Squash with Sausage & Kale

Whole30 and Paleo Roasted Acorn Squash stuffed with ground sausage, kale and mushrooms. It’s a delicious & fast weeknight dinner, and guess what? It’s super kid-friendly, too!

It’s fall, y’all! [Full disclosure, I’ve been living in the South for five years but I don’t feel comfortable saying the word “y’all.” With my New York accent, it comes out like “yawl.” I have 100% claimed it when I write, though. I’m a Southern girl at heart, I guess.] In any case, it’s fall, and I really love squash at this time of year, especially acorn squash. The flavor is so rich and sweet, not to mention they make the cutest little serving boats ever. I’m so excited to share this recipe for Roasted Acorn Squash with Sausage, Kale & Mushrooms!

The really nice thing about acorn squash is there’s really no wrong way to cook them. You can bake them, cook them in the instant pot or slow cooker, heck, you can even microwave them! My preferred method is roasting, because I love how it gets all caramelized on the outside and soft and sweet on the inside. It can be a little tricky, though, so here are some tips for how I like to do it:

How to Make Roasted Acorn Squash in the Oven

Time needed: 1 hour.

Tips for Roasting Acorn Squash

  1. Microwave each squash alone for about 1 minute.

    This softens it just enough to make it a little easier to cut. Even with the sharpest knives, squash are really hard. 

  2. Make sure the squash is stable before you cut it. This is a LOT easier when you cut it on its side (NOT from stem to bottom).

    People sometimes don’t like to do this, because it won’t sit flat to function as a bowl to stuff the squash with other yummy goodness. The solution: Cut it sideways, roast it, and once it’s cooked and cooled a bit, you can easily trim the bottoms of each half so it sits flat. 

  3. Use a grapefruit spoon to scrape and remove the seeds.

    The sharpened edges on the grapefruit spoon make this job like a thousand times easier. 

  4. Score the flesh of the squash in a cross-hatch pattern before baking.

    This allows you to easily remove bite-sized pieces with a fork easily once it’s cooked. If you don’t do this, you’ll be man-handling your squash come dinnertime. 

  5. Drizzle the flesh with either:

    Olive oil, salt and pepper (savory) OR melted ghee, maple syrup, and a touch of cinnamon (sweet). For the recipe here, choose oil, salt and pepper.

  6. Lay on a parchment lined baking sheet, face up, and roast at 400 degrees for one hour.

    If you have a particularly large or small squash, either add or subtract about 10 minutes and watch closely near the end of the cook time.

Back to the recipe!

Okay, focus, Laura. Right now, I’m prepping to go out of town for Thanksgiving, so that means eating what’s left in the fridge and pantry, avoiding a trip to the grocery store at all costs. I had a few acorn squash to roast, so I did a quick search of what I had to see what I could use to make a meal.

Usually when I forage in my fridge, I almost always come out with eggs and make a frittata using whatever extra veggies I have on hand. That’s kind of what I love most about frittatas – you can whip up a delicious one in no time! Just check out my super simple Whole30 Chorizo and Potato Frittata recipe, or my Whole30 Sausage and Broccoli Frittata recipes. Not this time. Don’t get me wrong, I love eggs, but I just wasn’t feeling it. I found an 8oz package of baby bella mushrooms, ground sausage, and half of a bunch of kale.

And man, the stars just aligned on this one, because it was good. Like, really good. I just love it when things work out so perfectly like that, don’t you? I couldn’t have planned it better if I tried. 

If your kids HATE mushrooms (mine do, too):

Here’s a pro tip for you: If your kids hate mushrooms, dice them up really small.. I mean REALLY small, and sauté them with ground sausage. The mushrooms take on the flavor of the sausage. Most importantly, the texture ends up really similar! I suspect texture is the biggest culprit for why my kids won’t eat mushrooms, so this is super important!

My five year old was spooning the sausage mixture into his mouth, barely swallowing before shoving more in. And as much as his table manners are lacking, I love to see him enjoying the food I make (especially when I sneak him extra veggies, muah ha ha).

Simple = Best

This meal is made of literally five ingredients (besides the oil, salt and pepper, I mean). Does it get any easier than that? And hello, it’s unbelievably flavorful and filling. It’s just one of those meals that can warm you up when you come in from the cold, nose and cheeks still rosy. And once the acorn squash are roasted (which you can do in advance, by the way), the whole meal comes together in about 10 minutes.

My family gobbled this up! My husband just kept repeating, “This is SO good.” And that makes me feel good. Hope you enjoy this Roasted Acorn Squash Stuffed with Sausage, Kale & Mushrooms as much as we did!
