Vegan Stuffed Acorn Squash featuring a Mediterranean quinoa-chickpea filling is a delicious seasonal main dish. Not only are they stunning and full of flavor, they can be prepped in advance. Perfect for Thanksgiving!
The traditional holiday dinner gets a vegetable-centric makeover when you serve these mild and buttery winter squash filled with seasoned quinoa, chickpeas, and tomatoes. While my go-to main for Thanksgiving is Lentil Meatloaf Muffins, colorful Vegan Stuffed Acorn Squash is another seasonal favorite.
And though it may seem like a complicated dish to prepare, it's actually quite easy. Plus you can save time by cooking the quinoa a few days in advance, or by making the quinoa stuffing for the squash ahead of time.

How many squash should you buy?
Each one will feed two people. This Vegan Stuffed Acorn Squash recipe calls for four, which makes eight servings. Feel free to make more or less, depending on how many guests you're serving.
Slicing open winter squash can be difficult since they are very hard. To make it easier, place the uncut squash in the oven directly on the center rack.
Turn on the oven to preheat. Allow the squash to remain in the oven while it heats up.
As soon as the oven is heated up to temperature, carefully remove the squash using oven mitts. Allow the squash to rest until they are cool enough to handle. Then slice each squash in half lengthwise and scoop out the seeds.
- Step 1: Slice the squash in half lengthwise and scoop out the seeds with a spoon.
- Step 2: Place the halves cut-side down on a baking sheet and roast.
- Step 3: Once the squash are nearly tender, remove the sheet pan from the oven. Carefully turn the halves over so they are cut side up and ready for stuffing.
- Step 4: While the squash is roasting in the oven, prepare the quinoa in a pot on the stove or in an Instant Pot electric pressure cooker. (Instructions for both methods are provided in the recipe at the bottom of this post.)
- Step 5: Saute the onion until soft and slightly translucent.
- Step 6: Add the carrots, celery, and garlic and saute until tender.
- Step 7: Add the cooked quinoa, chickpeas, tomatoes, lemon juice, and thyme leaves and mix everything together.
- Step 8: Cook, stirring occasionally, until everything is heated through and the tomatoes are soft.
- Step 9: Spoon the warm filling into the squash halves and let them bake for a few more minutes until fork-tender, then serve.
The savory filling can also be enjoyed on its own. Or try it in a Butternut Squash Buddha Bowl or in stuffed peppers or zucchini.
Or try adding in your favorite ingredients like pine nuts, dried cranberries, or mushrooms.
Storing and freezing
Leftover vegan stuffed acorn squash can be covered and refrigerated for up to 3 days. Reheat in the oven or microwave, or enjoy at room temperature.
Leftover filling can be covered and refrigerated for up to 3 days or frozen for up to 3 months. Defrost it in the refrigerator overnight before reheating.
For tips on freezing, refer to USDA Freezing and Food Safety.
While you may eat the cooked skin, I personally don't enjoy the texture. When it comes to winter squash, the only skin I eat is from delicata. For more information about squash skin, check out The Winter Squash Skins That Are Edible (and Those That Are Not).
Uncut acorn squash should be stored in a cool dark place for up to a month. There's no need to refrigerate them. In fact, they will last longer if they aren't refrigerated. If the squash is sliced but still raw, wrap the pieces in plastic wrap and refrigerate for up to 4 days.
Yes. If you cut open the squash and it's gray or slimy, toss it out.
Acorn squash can be very tough to slice. My favorite method is to place them in the oven directly on a rack while the oven is coming up to temperature. Once the oven is heated, carefully remove the squash. You should be able to slice it open much easier after a few minutes when it's cool enough to handle.
Cooked acorn squash can be stored in a covered container and refrigerated up to 3 days or frozen up to 12 months.
