Serves 4 | Prep Time: 10 minutes | Cook Time: 45m

Variety Tip: Use Ontario Idared, Golden Delicious, Honeycrisp, or Empire apples.


4 small-medium sized acorn squash, seeded, cut in half lengthwise
Salt and pepper 30 mL
2 tbsp olive oil
8 oz fresh mixed mushrooms (portabella, shiitake, oyster), coarsely chopped 227 g
2 celery stalks, thinly diced
2 Ontario apples*, peeled and finely diced
3 tbsp butter 45 mL
1 tbsp fresh sage leaves, finely chopped 15 mL
1 cup vegetable stock 250 mL
1/2 cup walnuts, roughly chopped 125 mL
5 cups (approx) 1 small loaf of day-old sourdough or French bread, cut into ¼ inch cubes


1. Preheat oven to 350°F/175°C.

2. Cut acorn squash in half lengthwise. Remove the seeds. Season the inside with salt and pepper. Place cut side down on a baking sheet lined with parchment. Bake about 30 minutes or until soft.

3. Meanwhile, in a large sauce pan heat olive oil. Add mushrooms and sauté for 3-4 minutes. Add celery and continue to sauté for 5 minutes. Lower heat and add apples. Continue to cook until apples become tender, about 5 minutes. To the pan add butter, sage, and vegetable stock. Heat just until butter is melted. Remove from heat and allow to cool.

4. Place chopped walnuts and diced bread in a large bowl. Pour warm vegetable stock mixture over bread. Using your hands toss the bread until it is well coated and most of stock is absorbed.

5. Remove squash from oven and turn it cut side up. Divide the stuffing among each squash half; spoon the stuffing into the cavity of each squash until filled. Return to 350°F/175°C oven and bake until stuffing is golden brown, approximately

15-20 minutes.

6. Serve hot alongside a festive ham or weeknight roast chicken.
