Simple Butternut Squash and Apple Casserole Recipe
I harvested more butternut squash than I knew what to do with this year, so I paired it with apples for something a little different: butternut squash and apple casserole. The combination surprised me in the best way! Sweet apples and caramelized squash come together with golden onions, honey, almonds, and Parmesan for a cozy, flavor-packed side dish.

WHY THIS RECIPE WORKS
- Flavorful side-dish: As much as I love a cozy bowl of butternut squash soup, I decided to pair the squash with apples instead. Each ingredient brings something different to the dish. The butternut squash and apples are tossed in a simple savory-honey marinade and baked until tender and beautifully caramelized, bringing out their natural sweetness.
- Caramelized onions: Sauté the onions separately until golden brown, giving them a rich, mellow sweetness without the sharp flavor of undercooked onion.
- Textures: Crunchy almonds and freshly grated Parmesan add savory depth and umami flavor.


I love it served on its own, but it also makes a wonderful side dish with white or brown rice, roasted chicken, or pork. And if you don’t have honey on hand, maple syrup makes a delicious substitute.
