Apple Butternut Squash Casserole

Apple Butternut Squash Casserole with bacon, pecans, and honey is a sweet and savoury holiday side dish with warm fall flavours.

This Apple Butternut Squash Casserole with Bacon-Pecan Topping is a delicious way to bring the flavours of fall to your dinner table. Tender butternut squash, sweet apples, and red onion roast with fresh sage and thyme, then get topped with crispy bacon, crunchy pecans, honey, and warm spices. The combination of savoury herbs, sweet fruit, and smoky bacon makes every bite a little different.

This easy butternut squash casserole is a lovely addition to Thanksgiving dinner, Christmas dinner, or any cosy autumn meal. It has the kind of sweet and savoury flavour that pairs beautifully with roast turkey, chicken, or pork, and the crisp bacon-pecan topping makes it feel a little more special than an everyday vegetable side. Best of all, the squash roasts while you prepare the topping, so it comes together without too much fuss.

Tips for Best Results

• Cut the squash evenly – Aim for similar-sized cubes so the squash cooks at the same rate. Smaller cubes will cook faster than larger ones.
• Choose firm apples – Honeycrisp, Granny Smith, and Pink Lady apples hold their shape well during roasting.
• Don’t overcrowd the baking dish – Spread the squash, apples, and onion in a reasonably even layer so they roast rather than steam.
• Cook the bacon until crisp – The bacon will soften slightly when mixed with the honey and pecans, so start with properly crisp pieces.
• Let the bacon cool before mixing the topping – This helps prevent excess grease from making the pecans soggy.
• Watch the topping closely – Honey can brown quickly, so keep an eye on the casserole during the final 10 minutes.
• Season in layers – Season the squash mixture first, then taste the bacon-pecan topping before adding more salt. Bacon can be quite salty already.
• Let it rest before serving – A five-minute rest helps the flavours settle and makes serving easier.

Ingredients and Substitutions

• Butternut squash – The main ingredient, with a naturally sweet, creamy texture when roasted. You can substitute another firm winter squash, such as kabocha or acorn squash, adjusting the cooking time as needed.
• Apples – Add sweetness and a little tartness. Use firm apples such as Honeycrisp, Granny Smith, or Pink Lady to help them hold their shape.
• Red onion – Adds savoury flavour that balances the sweetness of the apples and honey. Yellow onion or shallots also work.
• Coconut oil – Used to roast the vegetables and coat the topping. Olive oil or melted butter can be used instead.
• Fresh sage – Adds a classic autumn flavour. Use about ½ teaspoon dried sage if fresh isn’t available.
• Fresh thyme – Brings a gentle herbal flavour. You can substitute about ½ teaspoon dried thyme.
• Bacon – Thick-cut bacon provides smoky flavour and crunch. Regular bacon works too, though it may cook more quickly.
• Pecans – Add buttery crunch to the topping. Walnuts are a good substitute.
• Honey – Sweetens the topping and helps the pecans brown. Maple syrup can be used for a different flavour.
• Ground cinnamon – Adds warmth and complements the apples and squash.
• Ground cloves – Provides a deep, aromatic spice. Use sparingly, as cloves have a strong flavour.
• Sea salt and black pepper – Bring out the flavours and balance the sweetness.
