The natural sweetness of apples pairs beautifully with the earthy notes of butternut squash. It’s not overly sugary, making it versatile enough to sit beside roasted meats or even be served as a light vegetarian main. With a sprinkle of herbs and a buttery finish, this dish is an autumn staple you’ll want year-round.

What Kind of Apples Should I Use?

The best apples for this casserole are ones that hold their shape during baking. Go for sweet-tart varieties like Honeycrisp, Fuji, or Braeburn. These add a delightful balance without turning mushy in the oven. Mixing two types can also add flavor depth.

Ingredients for the Apple Butternut Squash Casserole

Butternut Squash
The star of the dish, its creamy texture and subtle sweetness pair wonderfully with the apples.

Apples
Choose firm, slightly tart varieties to balance the sweetness and hold up during baking.

Maple Syrup
Adds a cozy caramel flavor and enhances the natural sweetness.

Butter
For that rich, indulgent finish and to help crisp the topping.

Cinnamon & Nutmeg
These warm spices are essential for giving the casserole that signature fall flavor.

How To Make the Apple Butternut Squash Casserole

Step 1: Prepare the Produce

Peel and cube the butternut squash. Core and slice the apples into bite-sized chunks. Make sure both are roughly the same size so they bake evenly.

Step 2: Season and Toss

In a large bowl, combine the squash and apples. Drizzle with melted butter and maple syrup. Sprinkle in the cinnamon, nutmeg, and a pinch of salt. Toss to coat evenly.

Step 3: Assemble in Baking Dish

Transfer the mixture into a greased casserole dish. Spread it out in an even layer.

Step 4: Add the Topping

Mix crushed cornflakes (or breadcrumbs) with a bit of melted butter and chopped thyme. Sprinkle this mixture generously over the top.

Step 5: Bake to Perfection

Bake at 375°F (190°C) for 35-40 minutes until the squash is fork-tender and the topping is golden brown.


How to Serve and Store This Casserole

Serve this casserole warm, straight from the oven, garnished with a little extra thyme if desired. It’s hearty enough for a main dish or perfect as a flavorful side.

To store, let the casserole cool completely, then cover tightly or transfer to an airtight container. It keeps well in the fridge for up to 4 days. To reheat, warm in a 350°F oven until hot, or microwave single servings.
