1. Roast the Squash and Apples: Preheat oven to 425°F (218°C). Toss the cubed butternut squash and apples with olive oil, salt, pepper, 1 tablespoon maple syrup, dried sage, and Herbes de Provence. Spread on a baking sheet and roast for about 35 minutes, stirring occasionally, until tender and golden.
2. Cook the Sausage: In a large skillet over medium-high heat, add a drizzle of olive oil. Cook the crumbled sweet Italian sausage until browned and cooked through. Remove from the pan and set aside.
3. Caramelize Fennel and Onions: In the same skillet, add a bit more olive oil if needed. Sauté the sliced fennel and onion until deeply golden and caramelized, about 10-12 minutes. Remove from heat.
4. Assemble the Casserole: In a large bowl, combine the roasted squash and apples, cooked sausage, and caramelized fennel and onions. Add the remaining 1 tablespoon of maple syrup and toss gently to combine. Season with additional salt and pepper to taste.
5. Bake: Transfer the mixture to a medium-sized (approximately 9×13 inches) baking dish. Sprinkle the grated Gruyere cheese evenly over the top. Place under the broiler for a few minutes until the cheese is melted and golden-brown.
6. Garnish and Serve: Top with fresh sage leaves and serve warm.

Notes:

• Vegetarian Option: To make this casserole vegetarian, omit the sweet Italian sausage.
• Cheese Alternatives: For a different flavor profile, consider using sharp white cheddar or fontina cheese in place of Gruyere.
• Make-Ahead: Prepare the casserole up to the baking step, cover, and refrigerate. When ready to serve, bake as directed, adding a few extra minutes if needed.
