Instructions

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. Bake:

    Bake for 20 minutes, or until the topping is golden brown and the casserole is heated through.
