How to Make Baked Acorn Squash With Brown Sugar and Walnuts

You’ll have a hard time finding a Thanksgiving side dish that’s easier than this one. Just set aside 5 minutes for prep, and your oven will be free again in under an hour.

  1. Prep the Squash: Cut your squash in half lengthwise, scoop out the seeds and place the halves on a baking sheet with the cut sides up. Coat them in olive oil and sprinkle salt and pepper over the tops. Pop them in the oven at 400°F for around 45 minutes, or until they get that buttery texture and caramelized coating.
  2. Add the Filling: Once the squash has roasted, it’s time to add that sweet, buttery, nutty filling! Mix butter, brown sugar, and a tablespoon or so of chopped walnuts together and add them to the pocket where the seeds used to be in each half of the acorn squash.
  3. Finish Baking and Serve: Stick the squash back into the oven for another 8-10 minutes, or until the butter melts and the walnuts get nice and toasty. Either mash all the ingredients together, or slice the squashes up into 8 equal pieces to serve.

Can I Make This in Advance?

While the buttery texture and caramelization are best right after the squash is roasted, there’s a lot of prep you can do ahead of time. You can cut the squash and remove the seeds up to 24 hours before you plan to use it. Feel free to mix together the filling in advance too. When you’re ready, just stick the squash in the oven and let it do its thing.

Tips for Success

Roasting squash couldn’t be easier! Make sure to check out these tips so your squash comes out amazing every time.

  • Make Slicing Easier: If you’re having trouble cutting your fruit in half, pierce the squash with a fork several times on each side and then microwave it for 5 minutes. The squash will be much easier to cut through afterward.
  • Keep the Cut Side Up: Make sure you roast your squash with the cut side facing up. If the cut side is pressed against the baking sheet, it won’t form the beautifully caramelized coating.
  • Final Prep: It’s up to you whether you want to mash the squash and mix the fillings in or leave the structure as-is. I like to mix everything together first so that I get some of each flavor in every bite.

Variation Ideas

It’s so easy to put your own spin on this simple recipe. Here are a few suggestions to get the ball rolling.

  • Switch Up the Nuts: Pecans, hazelnuts, pine nuts, almonds and pistachios all make great replacements for the walnuts in this recipe.
  • Replace the Brown Sugar: If you feel like switching it up, you really can’t go wrong with sweeteners in this recipe. Honey, maple syrup, and molasses all come with additional health benefits, or you can use white sugar or a sugar substitute.
  • Add Fresh Herbs: Feel free to throw in some fresh sage, rosemary or parsley instead of chives. You can really customize this side dish to your liking. It’s just a matter of roasting the squash and filling it with good stuff.

Serving Suggestions

I love to serve this side dish alongside my Thanksgiving Turkey. It fits in just as well during the winter holidays paired with a sweet, glazed Spiral Sliced Ham. But you don’t have to wait for a special occasion. This roasted squash goes just as well with a simple chicken or steak dinner as it does with your holiday meal!

Storing and Reheating Extras

Don’t worry if you have half a squash left over. You can wrap each half individually in foil and pop it in the fridge for up to 2 days. When you reheat them, leave the foil where it is so that it traps the moisture and keeps the squash from drying out. Stick them in the oven at 400°F until they’ve just warmed through.

Can I Freeze Roasted Acorn Squash?

If you want to freeze leftover squash, make sure you mash it up first. It won’t be very appetizing if you try to eat it plain after defrosting it, but it makes a great soup base or pie filling. You can also freeze fresh, uncooked squash for meal prep by cutting it into cubes. Either way, it’s best if you defrost and use it within 3 months.
