Butternut Squash Casserole Recipe
Butternut squash casserole is a cozy classic, perfect for fall and holiday gatherings. It combines creamy, sweet butternut squash with flavorful additions like cheese, herbs, or a crunchy crumb topping. These ingredients make it have a perfect balance between savory and a hint of sweetness.

My casserole includes a smooth, creamy base seasoned with nutmeg and cinnamon, a crisp layer of breadcrumbs for added texture. Its luxurious texture and golden topping make it a beautiful centerpiece, whether you serve it for a family dinner or bring it to a potluck.
You can serve this dish as a side or enjoy it alone as a hearty vegetarian entrée. It’s rich enough to satisfy but never feels heavy. It’s a go-to comfort dish throughout the colder months.
The dish pairs beautifully with roast meats such as turkey, chicken, or lamb. It also makes a great match for seafood like baked salmon or herb-roasted cod. For a vegetarian feast, the casserole works alongside dishes like wild rice pilaf, sautéed green beans, or a crisp kale salad.
Comfort foods like mashed potatoes, cornbread, and stuffing go well with butternut squash casserole, especially for holiday spreads. When served at brunch, it pairs delightfully with quiche, a medley of roasted vegetables, or a fresh fruit salad.
