Stuffed Acorn Squash

Hello friends! Welcome to Djalali Cooks, I am so happy you’re here today. Thanksgiving is only three weeks away! Can you believe it?! It’s not often I bake sweets for us at home, but my Pumpkin Cream Cheese Muffins last weekend have inspired me to go full-on fall flavors this year. It’s no wonder really, fall flavors are comforting and warm. And who doesn’t want that this year?Fall isn’t fall without squash; butternut, acorn, spaghetti, pumpkin…there are so many great recipes for squash. Today, I want to share a Stuffed Acorn Squash recipe that is perfect for customizing to your personal taste.

Herbs and spices really play up the fall flavors for the stuffing, while the squash and caramelized onions lay the foundation flavor. For the stuffing, I have one pound of ground pork but you can use turkey or beef if you like. To that we will add mushrooms and the caramelized onions. Let’s get started: preheat your oven to 450 degrees. Then, let’s get the onions going because they will take about an hour.

This is when a mandoline slicer will be your best friend. It makes very quick and tearless work of thinly slicing a large yellow onion. Pour 1-2 tablespoons of olive oil into your large skillet and heat it over low heat while you slice the onions. Toss in your sliced onions and add a generous pinch of salt. Give it a stir and revisit every 10 minutes or so to give it another stir.

When the onions have been on for about 30 minutes, cut your Acorn squash in half and scoop out the seeds. You can do two Acorns for four people; or you can do one Acorn, for a two person serving – with leftover filling for another dish later in the week.

Place the squash, cut side up on a sheet pan and drizzle with olive oil. Sprinkle a good pinch of kosher salt and a pinch of black pepper over each half. Then, turn them cut side down and bake for 20 minutes, or until they’ve browned and have a soft texture when poked with a fork.

While the Squash is roasting, brown your ground pork in a skillet over medium high heat. Add a generous pinch of salt at the start of cooking and stir, breaking up the meat as it cooks. Once it’s mostly cooked through, add the spices: 2 teaspoons celery seed, 1 teaspoon garlic powder, 1 teaspoon ground sage.

Stir to combine then add your roughly chopped mushrooms.

Once you’ve stirred in the mushrooms, add 1 teaspoon soy sauce, turn the heat to medium low and let the mixture cook down for about 10-15 minutes. Give it a taste test and add a little more salt if you think it needs it.

Now your Squash should be ready. When you pull your squash, leave the oven on. The onions have been on for about an hour now…

Onions after one hour, they could easily go for another half hour or more. I will let these cook another 10 minutes while I prep my toppings.

The squash is out of the oven and the pork mushroom mixture is simmering. My onions are cooking for another 10 minutes. Now, let’s add some fresh rosemary and sage leaves to the pork mushroom mixture. Remove about one teaspoons’s worth of fresh rosemary leaves from their stems and give them a rough chop. Then, chiffonade* about 6-8 sage leaves and stir the fresh herbs into the pork and mushroom mixture.

*Chiffonade cut: Stack the leaves, roll them tightly, then thinly slice the leaves perpendicular to the roll.

You can go so many different ways with the toppings for this dish. I am doing toasted walnuts, grated parmesan and more fresh rosemary. But another great way to go would be toasted walnuts with blue cheese crumbles and dried cranberries. Or toasted pine nuts, feta and fresh oregano.

Toast your nuts (about a cup) on the stovetop over medium low, in about a tablespoon of salted butter. You can add whatever spices you like. I have added a little cayenne and a teaspoon of sugar to mine. Once they become golden and fragrant (about 5 minutes), they’re done!

So now, let’s combine the pork and mushroom mixture with the onions. Be sure to mix them in well, so that you won’t have clumps of onions. Then use a slotted spoon to fill each squash. you can fill and pack it down a bit then mound another spoon-full on top. Put in the 450 degree oven for 5 minutes.

Plate up your Stuffed Acorn Squash!

Place each squash on a plate and drizzle some olive oil over the whole thing, then sprinkle on the cheese, walnuts and rosemary leaves.

    I made the stuffed acorn a couple of nights ago. Mixed it with beef and pork. It was delish! Lovely flavors. Thank you for posting it. Looking forward to making the pumpkin cream muffins and the braised short rib. Best of luck with your site.
