How to Make Vegetarian Stuffed Acorn Squash

1. Prep the squash

Place the squash on its side, use a sharp kitchen knife, place it horizontally across the top of the squash and slice the top off about ¾ inch below the stem. Then carefully place the knife horizontally in the center of the squash and slice it down the middle. You can cut the squash either vertically or horizontally down the center.

Use a spoon to scoop out the seeds and scrape the inside to get it nice and clean.

2. Roast the squash

Preheat the oven to 375° F, and spray a baking sheet with cooking spray.

Brush each half of the squash with some of olive oil and sprinkle each generously with salt and pepper. Place the squash, face-side down onto the baking sheet and bake for 25-30 minutes, remove and let cool.

The squash can be prepared 1–2 days in advance at this stage. Let it cool, then store it in an airtight container in the fridge until you are ready to fill it. Warm it at 350°F on a pan in the oven for about 10 minutes before you fill it.

3. Make the filling

Heat a skillet to medium heat, and add 1 tablespoon of olive oil. Once hot, add in the minced garlic, minced shallots, and sliced mushrooms.

Cook for 4-5 minutes, tossing gently as it cooks until the veggies start to brown.

Add in the spinach and sprinkle everything with salt and pepper. Cook until the spinach is slightly wilted.

Push the veggies to the side of the pan and pour in the chickpeas and chopped walnuts. Sprinkle the chickpeas with the spices—onion powder, cumin, chili powder—and sprinkle with salt and pepper. Toss and let them cook for 2-3 minutes to get them nice and golden.

Add in the cooked wild rice, toss everything together, and let cook for 2 minutes.

Sprinkle in the Parmesan cheese and let it melt into the mixture. Pour in the orange juice and zest and toss. Add in the dried cranberries and let that all cook for 1 minute to get the cranberries slightly plump.

4. Fill and bake the squash

Fill each squash with the filling. The recipe recommends filling them generously. Store any remaining filling for another meal.

Top each stuffed squash with more cheese if desired and bake in the oven at 425° F for 4-5 minutes to get the tops nice and golden brown.

5. Serve

Serve warm and top with fresh herbs like sliced basil or parsley.

Important Cooking Tips

• Choose a good acorn squash: Look for one with a lot of green and less orange or white coloring, very few blemishes, and dull skin.
• Avoid overly shiny skin: The recipe notes that shiny skin means the squash was picked too early and may not have as much flavor.
• Clean the squash thoroughly: Scoop out the seeds and scrape the inside before roasting.
• Watch the vegetables as they cook: The mushrooms should start to brown, and the spinach should become slightly wilted before moving on.
• Give the chickpeas and walnuts time to brown: Cook them for the specified 2-3 minutes after adding the spices.
• Don’t discard the extra filling: Any remaining filling can be stored for another meal.

Storage & Make-Ahead

The roasted squash can be prepared 1–2 days in advance. After cooling, store it in an airtight container in the refrigerator. Warm it at 350°F for about 10 minutes before filling.

For freezing, place one half of the stuffed squash into a freezer-friendly quart-sized bag and remove as much air as possible. Place it in the fridge to cool completely, then transfer it to the freezer. When ready to eat, remove it from the bag and microwave on high from frozen for 5-7 minutes.
