Preheat your oven to 400℉, 204℃
Prep the acorn squash: Cut both acorn squash in half and use a spoon to scoop out the internal seeds. Place all four halves on a parchment-lined baking sheet flesh side up. Drizzle a little bit of olive oil over each half along with a pinch or two of salt & black pepper.
Place the acorn squash into your heated oven and let them roast for roughly 30 to 45 minutes. You will know that the acorn squash is fully cooked when its flesh is easily pierced by a fork.
Cook the bulgur wheat: Place the bulgur wheat into a pot with 1 cup of water/vegetable stock and a pinch of salt. Place this pot over high heat and let it come to a boil. Place a lid on the pot and reduce the heat to low. Let the bulgur wheat cook until all of the liquid is absorbed, about 15 minutes. Take it off of the heat, let it rest for 10 minutes, then fluff with a fork.
Make the stuffing: Pour 2 tablespoons of olive oil into a large skillet/pan and place over medium-high heat. Toss in the onion and celery, and sautee both ingredients for roughly 5 minutes. Then add the mushrooms, cranberries, pepitas, garlic, sage, and thyme to the skillet/pan. Continue to sautee everything for an additional 5 minutes, or until the mushrooms are fully cooked. Take the skillet/pan off of the heat, and toss in the cooked bulgur wheat. Add in the lemon juice along with a couple of pinches of salt & black pepper. Stir to combine everything, then taste and adjust with more salt and black pepper until it’s to your liking.
Spoon the stuffing into the cavity of each acorn squash halves. Return the stuffed acorn squash to your oven and let them cook for an additional 15 minutes.
Serve the stuffed acorn squash with a sprinkle of minced parsley and enjoy!
