Ingredients needed for this amazing recipe

How to make Vegetarian Stuffed Acorn Squash

First, you need to prep and roast the acorn squash – a very easy step that I do almost weekly in the fall, just so I can have acorn squash on hand all week.

1. Prep the squash: Use a sharp kitchen knife to slice the ends off of the squash about 3/4 inch below the stem. This will help the squash sit nice and flat when roasting. Scoop out the seeds and excess pulp from inside the squash. Scrape the inside with the back of the spoon to get it nice and clean for roasting.
2. Roast the squash: Preheat the oven to 425 degrees F and brush the squash with olive oil and sprinkle with salt and pepper. Place it onto a baking sheet and roast for 25-30 minutes.
3. Make the filling: While the squash is roasting, you can make the filling. It’s so good! Start by sautéing the mushrooms, garlic, and shallots in a little olive oil until the mushrooms start to brown. Then add in the spinach and a sprinkle of salt and pepper and cook until the spinach is slightly wilted. Pour in the chickpeas and walnuts and toss in the spices. I used onion powder, cumin, and chili powder. Let that all cook for 2-3 minutes to wake up the spices and get the chickpeas slightly golden brown. Finally, add in the cooked wild rice, toss, and let that all cook for 1-2 minutes.
4. Add the cheese: Sprinkle in the grated parmesan cheese and toss to allow it to melt a little. Add in the juice and zest of an orange and the dried cranberries as the final touch. Toss everything together. Expert tip: Before adding the dried cranberries to the filling, I like to plump them up a little bit by letting them sit in a bowl filled with a little warm water for about 5 minutes.
5. Fill and bake: Fill each squash half with the rice and chickpea filling. I like them to be pretty stuffed, almost overflowing. Bake at 425 degrees F for about 5-7 minutes, until the tops are nice and golden brown. Top with more cheese if desired.
