Preparing Vegetarian Stuffed Acorn Squash
Preheat oven to 375°. First, wash and cut each acorn squash from stem to end. Remove seeds from the inner core using a spoon.
Shopping Tip: Select similar sized squash for even cooking.
Place each squash half flesh-side down on a parchment-lined baking sheet. Cook rice on stove top while squash is baking. Chop and slice all additional vegetables.
Bake squash for 30 minutes or until fork tender and remove from oven.
Heat vegetable oil in sauté pan. Sauté onions and celery for five to six minutes until soft.
Add mushrooms, garlic, thyme, sage, salt and pepper. Sauté for another three to four minutes.
Combine vegetable mixture with cooked rice. Fill each squash core with rice mixture.
Tasty Tip: If you have excess rice, transfer the squash to a casserole dish before filling. Once each half is filled, spoon the extra rice around the squash.
Bake squash for additional five to ten minutes depending on length of time cooled. While stuffed squash is baking, crumble prepared cornbread in a small bowl and mix with shredded Parmesan cheese.
If you’re preparing this dish at Thanksgiving, prepare homemade cornbread for your dressing and save a small amount for this cornbread topping. Otherwise, you could buy a small amount of cornbread from your local bakery.
Remove squash from oven and sprinkle each half with cornbread topping. Bake an additional five minutes until topping is golden brown.
