About the Ingredients

Butternut Squash

This winter squash has a naturally sweet, nutty flavor that gets even richer when roasted. Look for one that feels heavy for its size with firm, unblemished skin. A medium butternut squash typically weighs about 2-3 pounds.

For this recipe, we're roasting the entire squash cut in half, rather than peeling and cutting it into cubes. It's much easier to prepare this way!

Olive Oil (or Butter/Coconut Oil)

You can use any of these! Olive oil gives a lighter flavor, butter adds richness, and coconut oil adds a subtle sweetness. All three help the squash roast beautifully.

Cinnamon, Allspice, and Nutmeg

These warm spices give the squash its cozy fall flavor. You can adjust the amounts to taste, use less nutmeg or allspice for a milder flavor, or keep it simple with just cinnamon if you prefer.

Brown Sugar (Optional)

Butternut squash is naturally sweet, so brown sugar is completely optional! A small sprinkle adds extra sweetness and enhances the roasted flavor.

How to Make Oven Roasted Whole Butternut Squash (Step by Step)

First, preheat your oven to 400°F and gather your ingredients.

You'll need:

• 1 medium butternut squash
• 1 tablespoon olive oil (or melted butter/coconut oil)
• 1 teaspoon cinnamon
• 1 teaspoon allspice
• 1 teaspoon nutmeg
• 1 teaspoon brown sugar (optional)

1. Prepare the Butternut Squash

Cut a small slice off the bottom of the butternut squash to create a stable base. Stand it upright on a cutting board and carefully cut it in half lengthwise using a sharp knife.

Scoop out the seeds and stringy center with a spoon.

2. Season the Squash

Place the squash halves cut-side up in a baking dish.

Brush the exposed flesh with olive oil, melted butter, or coconut oil.

Sprinkle the cinnamon, allspice, nutmeg, and optional brown sugar evenly over the squash.

3. Roast the Butternut Squash

Place the baking dish in the preheated oven and roast at 400°F for about 1 hour, or until the squash is tender and easily pierced with a fork.

Cooking time depends on the size of your squash. Start checking around the 45-minute mark. Larger squash may take up to 1½ hours.

If the surface starts browning too quickly, loosely cover it with aluminum foil.

4. Serve and Enjoy!

Remove the squash from the oven and let it cool slightly before serving.

You can serve the roasted halves as-is, scoop out the soft flesh and mash it, or use it in soups, salads, and other recipes.

The squash turns wonderfully soft and creamy, with a naturally sweet flavor that goes perfectly with the warm spices!

Storage and Reheating

How to Store Roasted Butternut Squash

Let the roasted squash cool slightly, then transfer it to an airtight container and refrigerate within 2 hours of cooking.

Store leftovers in the refrigerator for up to 3-4 days.

Can You Freeze Roasted Butternut Squash?

Yes! Roasted butternut squash freezes well.

Scoop out the cooked flesh and transfer it to a freezer-safe container or bag. Freeze for up to 3 months for the best quality.

Thaw overnight in the refrigerator before reheating.

How to Reheat

• Microwave: Place the squash in a microwave-safe dish and heat in short intervals, stirring or checking between each, until thoroughly heated.
• Stovetop: Warm the squash in a small pan over medium-low heat, stirring occasionally.
• Oven: Place in an oven-safe dish and reheat at 350°F until heated through.

For food safety, reheat leftovers to 165°F.

The squash stays soft and creamy, making it great for preparing ahead of time!

Frequently Asked Questions

Can I roast butternut squash ahead of time?

Yes! This is a great make-ahead side dish, especially for Thanksgiving. Roast the squash up to 2 days in advance, store it in the refrigerator, and reheat before serving.

Do I need to peel the butternut squash first?

Nope - that's one of the best parts of this recipe!

Since you're roasting the squash in halves, there's no need to peel it beforehand. Once cooked, the flesh becomes soft enough to scoop right out of the skin.

How do I know when the butternut squash is done?

Insert a fork into the thickest part of the squash. If it slides in easily and the flesh feels very soft, it's ready!

Can I change the spices?

Definitely! You can use just cinnamon, substitute pumpkin pie spice, or make a savory version with salt, black pepper, garlic powder, or paprika.

What can I do with leftover roasted butternut squash?

There are lots of ways to use it! You can mash it as a side dish, blend it into soups, add it to grain bowls or salads, or even stir it into oatmeal for a cozy fall breakfast.
