Stuffing Stuffed Butternut Squash

If your refrigerator looks like mine the day after Thanksgiving, you are looking at many leftovers. Leftovers are one of my family’s favorite parts of Thanksgiving. There are some fun ways to use the leftovers, but we love stuffing them into roasted winter squash!

Every year, we have so many leftovers after Thanksgiving. Turkey, mashed potatoes, gravy…but NEVER stuffing. Gluten free stuffing goes fast in this house! This year, I made a triple batch, which was more than enough! Try my homemade Gluten Free Stuffing recipe in this recipe! Super yum!!

This is sort of what happened with this recipe. It all started with a beautiful butternut squash from our local farmer’s market. I had wanted to tie this butternut squash with my leftovers.

I have a lot of fun gluten free winter squash recipes for even more recipe inspiration!

Step-By-Step Photos and Directions:

This leftover Thanksgiving stuffing recipe is so easy to make! Preheat the oven to 375º F.

A butternut squash cut in half on a cutting board.

Step 1: I sliced the butternut squash in half. Scoop out the seeds and roast them partway. This gives you nice cavities to stuff with your leftovers!

Ways to Cook Butternut Squash:

  • In this recipe, I roasted the butternut squash in my oven for 20 minutes before stuffing them. This gives them time to soften and caramelize without burning any stuffing.
  • If you are in a hurry, you can microwave the butternut squash to get it ready to stuff quickly. Place the de-seeded butternut squash halves face down in a microwave-safe dish. Cook for 8-10 minutes on high, depending on your butternut squash size.

Step 3: Mix your stuffing and leftover mixture in a large mixing bowl. My stuffing mixture contains leftover turkey, stuffing, mushrooms, pecans, and mozzarella cheese. The flavors bake in wonderfully with the butternut squash.

Step 4: Bake for an additional 20-25 minutes. If the stuffing gets too brown, cover it with aluminum foil. Serve it hot as a meal or a side dish.

  1. Your recipe has all the right ingredients but none of the right cooking instructions. Cook the squash as you would to eat it as a side dish. In other words cut in half , scoop out the seeds and cook covered with a little water in the oven for at least 45 minutes. Then put all your mixed ingredients into the cooked squash. Extra ingredients can go in the end that is cut in half and filled with stuffing. Extra stuffing can be put around the pan . Then cook it for 20-30 minutes. Till all is really done. You can also put cranberry sauce on the finished food.

  2. The instructions say to bake until the cheese melts, however I don’t see any cheese listed among the ingredients. How much cheese, what kind, and when/where do we add it? Sounds delicious!
