Instructions

Prepare the Squash:
Preheat oven to 400°F (200°C). Toss the butternut squash cubes with olive oil, salt, and pepper. Spread them on a baking sheet and roast for 25–30 minutes, or until tender and lightly browned. -
Sauté the Aromatics:
In a skillet, melt butter over medium heat. Add the chopped onion and garlic, cooking until soft and fragrant, about 5 minutes. -
Make the Squash Mixture:
Transfer the roasted squash to a large bowl and mash until mostly smooth. Add the cooked onion and garlic, milk or cream, eggs, Parmesan cheese, and nutmeg. Mix well to combine. -
Assemble the Casserole:
Spoon the mixture into a greased 2-quart baking dish. In a small bowl, combine breadcrumbs, melted butter, Parmesan cheese, and pecans. Sprinkle this mixture evenly over the top. -
Bake:
Bake for 20 minutes, or until the topping is golden brown and the casserole is heated through.
