How To Make Stuffed Acorn Squash

Stuffed acorn squash is so much fun to make and bring to the table.

The stuffing can be prepared in advance and then assembled and baked right before serving!


How To Roast Acorn Squash

As you would expect, acorn squash is part of the squash family. It’s considered a winter squash, similar to butternut squash, but is also related to the wonderful summer yellow squash and zucchini, too.

Butternut squash has a very tough core to cut through, and though acorn squash isn’t as soft as yellow squash, it’s still much easier to cut than butternut squash.

EXPERT TIP: For this dish, you’ll need to cut the squash in half, between the two ends. But first, start by cutting a small slice off each end. Don’t cut too much off, or you’ll cut into the center. Next, take a large knife, preferably a chef’s knife, and use a little force to push the knife through the center of the squash, cutting it in half. Now, use an ice cream scooper, or spoon, to remove the seeds and stringy flesh in the center of each half.

Next, place the squash halves, cut-side up, in a large baking dish.

Brush the flesh all over with olive oil.

Sprinkle with salt and pepper, and then bake for 40 minutes in an oven preheated to 400°F. After roasting, you should be able to easily pierce the inner flesh with a knife.

A Wonderful Vegetarian Dish

For the stuffing, we turn to one of our favorite ingredients in the world, OZO Foods’ Protein-Based Ground!

Of course, you could make this stuffing with ground pork, or even Italian sausage, but this protein-based ground is so deeply flavorful, you honestly will be amazed that it’s not meat.

EXPERT TIP: The OZO Plant-Based Ground is naturally flavored and packs big flavors into the ground crumbles, so it doesn’t require a lot of seasoning. We simply add a little salt, pepper, and 1 tsp of dried oregano. Then we sauté chopped onions, celery, and garlic, and add it all back together in the saucepan. It’s the perfect base for the flavorful filling.

In addition to the wonderful OZO Plant-Based Ground protein and sautéed vegetables, we add classic holiday ingredients, including:

  • Dried cranberries
  • Chopped pecans
  • Fresh chopped sage
  • Parmesan cheese
  • Bread crumbs

Simply stir all the ingredients together in a large glass bowl. The smell is classic holiday fare.

We love to mound enough of the filling so it extends upwards from the squash.

EXPERT TIP: You can find acorn squash in the produce section of most well-stocked supermarkets. You’ll notice they come in different sizes, ranging from small to medium-sized. If you want to serve these as a side dish, then go with the small. This recipe will fill 8 small halves (4 squash). If you’re serving as an entree, this recipe will fill 4 halves (2 squashes).

We love using Italian Panko bread crumbs in this recipe, but any type of bread crumb will work just fine.

After topping, all you’ll need to do is return the stuffed acorn squash to the oven for another 15 to 20 minutes.

  • 9"x13" baking dish (or similar size)


  • 4 small acorn squashes
  • 4 tbsp olive oil divided
  • Kosher salt and freshly ground black pepper
  • 12 oz OZO Protein-based Ground
  • 1 tsp oregano dried
  • 1 cup onion chopped
  • 1 cup celery chopped
  • 2 cloves garlic minced
  • 1 tsp sage fresh, chopped
  • ¼ cup cranberries dried
  • ¼ cup pecans chopped
  • ¼ cup Parmesan grated, plus 1 tbsp for topping
  • ¼ cup Panko bread crumbs Italian, plus 2 tbsp for topping
  • 1 tbsp Parsley chopped, for garnish, optional


  • Preheat oven to 400°F.
  • Snip the top and bottom off of each acorn squash. Don't cut too deeply, just enough so it can stand without being wobbly. Use a chef's knife, or a large knife, to carefully cut the squash in half, through the mid-section of the squash. Use a spoon to remove the seeds and stringy flesh on the inside of each half.
  • Brush olive oil (approximately 2 tbsp) all over the inside (and top edges) of the acorn squash halves. Liberally sprinkle all over with salt and pepper. Place in a baking dish and roast in the oven for 40 minutes.
  • Meanwhile, heat the plant-based ground in a large skillet over medium heat for 4 minutes, breaking it up as it cooks. Season with ½ tsp salt, ¼ tsp pepper, and the dried oregano. Transfer to a bowl and set aside.
  • In the same skillet, heat the remaining 2 tbsp of olive oil over medium heat. Add the chopped onion and celery and cook until soft and translucent, about 5 minutes. Add the minced garlic and cook for another 30 seconds.
  • Add the cooked protein-based ground to the cooked vegetables and stir until fully mixed. Let cool slightly and then transfer to a large bowl.
  • To the bowl, add the sage, cranberries, pecans, ¼ cup Parmesan, ¼ cup Panko, ¼ tsp salt, and pepper. Stir until fully mixed together.
  • Use a spoon to fill the cavities of the acorn squash. Mound enough so they are heaping.
  • In a small bowl, mix together 2 tbsp Panko Italian bread crumbs with 1 tbsp Parmesan cheese. Sprinkle about 1 tsp of the mixture over each of the stuffed acorn squashes.
  • Place back into the oven (still at 400°F) for 15 to 20 minutes, or until the tops are lightly browned. Remove from the oven and serve at once!



If you are serving these as a side dish, go with the smaller acorn squash that you find at your market.  If serving as an entree, go with the larger ones.
The filling can be made up to 2 days in advance.  Keep in an air-tight container in the refrigerator until ready to use. 
Ground pork or Italian sausage can be substituted for the plant-based protein, if desired.

    This is one delicious recipe. As you suggested, amounts varied depending on the size of the squash. Very flexible. I added a beaten egg to the stuffing to bind things a bit-just a personal preference. Plan to make more next week. Thanks for the recipe and your clear directions and suggestions.

    • Hi Susan! We are so happy you made the stuffed acorn squash! We love it so much, too, especially when it turns chilly outside! The addition of the egg is fantastic! Thank you so much for sharing and for the GREAT review. That means the world to us! Stay in touch! Kris & Wesley

    • Hi there! We really recommend the plant-based protein from OZO. But you could also go with cooked quinoa, or even cooked rice. Be sure to season it with salt and pepper. Dried oregano is good, too! Hope this helps!
