How to Make Stuffed Acorn Squash
While the steps in this recipe are lengthy, rest assured that they’re super easy and require very little hands-on time. Follow along below for the full how-to.
Step 1: Preheat the oven to 325°F, and season the roast with 1 teaspoon of salt. Place the ghee (or olive oil) in a heavy-bottomed or enameled cast iron pot over high heat. Once hot, sear the roast on one side for 4 minutes, then flip it over and remove the pot from the heat. Pour the broth into the pot until it reaches halfway up the roast, then place the lid on the pot, and bake for 3 hours.
Step 2: While the roast is in the oven, place the squash halves cut side down on a baking sheet or in a casserole dish, and bake for 1 hour and 15 minutes (at the same time as the roast).
Step 3: While the roast and acorn squash are in the oven, caramelize the onions. Add the butter to a heavy-bottomed pot over low heat, and once melted, add the sliced onions and 1 teaspoon of salt. Stir to combine, then place a lid on top, and let the onions wilt for 30 minutes. After 30 minutes, take the lid off the skillet and toss the onions in the butter. Turn the heat up to medium-low, and let the onions continue to caramelize, uncovered, for 45 minutes, scraping the pan and stirring the onions occasionally.
Step 4: Once the roast is finished, use two forks to shred it. Then, put the shredded beef, caramelized onions, cranberries, the final teaspoon of salt, and pepper in a large bowl and toss to combine. Stuff equal portions of the beef mixture into the squash halves. Raise the oven temperature to 375°F.
Step 5: If the acorn squash is still warm when you stuff it, bake for 10 minutes, until the beef is slightly browned the and stuffing is fully warmed through. If the acorn squash is cool when you stuff it, tent the stuffed squash with aluminum foil, and bake it for 25 minutes, until both the squash and stuffing are warmed through.
Step 6: While the stuffed squash is in the oven, make the sauce by whisking or blending together the Greek yogurt, lemon juice, grated garlic, salt, and thyme.
Step 7: Pour the sauce over the stuffed squash, sprinkle with fresh thyme leaves, if using, and serve!
Make-Ahead Tips
As mentioned above, this recipe is incredibly meal prep-friendly! By prepping the components below ahead of time, you’ll cut your kitchen time on the night-of by over 3 hours. Here’s how to prep:
- Make the roast – if you’ve got time over the weekend, throw the roast into the oven and let it cook while you do your at-home weekend things! When it’s done, shred it and store it in the fridge for up to 4 days.
- Caramelize the onions – similar to the roast, if you’ve got time to let the onions caramelize (very little actual hands-on time, but you’ll need to be in the house, of course) over the weekend, go for it! Once they’re done, store them in a jar or airtight container for up to a week.
- Pre-roast the acorn squash – go ahead and stick the halved acorn squash into the oven while the roast cooks. When it’s done, either cover the sheet pan with foil (and use the exact same pan for heating the stuffed squash on the night-of) or transfer the squash to an airtight container or bag, and store in the fridge for up to a week.
- Make the sauce – though this isn’t a HUGE time saver, it can still be helpful! Simply whisk together the ingredients and store them in a jar or airtight container in the fridge for up to a week.
Prepping these components means that on the night you plan on enjoying the meal, you’ll just need to combine the shredded beef, caramelized onions, and cranberries into a bowl, stuff the squash, and then bake everything until warmed through – easy as can be!
How to Serve
Serve the stuffed squash all on its own for a complete, delicious, and balanced meal, or, if you’d like to add a green veggie, alongside this simple arugula salad.
How to Store
Store any leftover stuffed squash in an airtight container in the fridge for up to 4 days. If you meal prepped the ingredients ahead of time (detailed instructions above), keep in mind that since they were cooked day(s) in advance, you’ll want to take that time into account when it comes to saving your leftovers (for example, if you cooked the beef on Sunday and enjoyed the stuffed squash on Tuesday, you’ll want to make sure you eat the leftovers by Thursday).
Reheat the stuffed squash either in the microwave for 1-2 minutes or in a 350°F oven for 12-15 minutes, until warmed through.
