I love how the high heat caramelizes the natural sugars in the squash, creating crispy edges and a tender interior. The fresh sage and salty parmesan take it over the top.
Whether you're a seasoned cook or just starting out, this dish is foolproof and sure to impress.
Why You'll Love This Recipe
About the Ingredients
1 medium butternut squash (about 2 lbs / 900g)
Look for one with a long neck and small bulb – it's easier to peel and has more flesh. You can also use pre-cut squash to save time.
2 tablespoons olive oil
Extra virgin olive oil adds flavor, but any neutral oil like avocado or canola works too.
1 tablespoon fresh sage leaves, chopped
Fresh sage is best, but you can use 1 teaspoon dried sage if that's what you have.
1/2 teaspoon salt
Use kosher salt or sea salt for the best flavor. Adjust to taste.
1/4 teaspoon black pepper
Freshly ground is ideal, but pre-ground works in a pinch.
1/4 cup grated Parmesan cheese
Freshly grated Parmesan melts better and has more flavor than pre-shredded. You can also use Pecorino Romano for a saltier kick.
Tips & Tricks
- Peel the squash with a sharp vegetable peeler – it's easier than using a knife and wastes less flesh.
- Cut the squash into uniform 1-inch cubes so they cook evenly. If some pieces are smaller, they'll burn before the larger ones are tender.
- Don't overcrowd the baking sheet – spread the cubes in a single layer with space between them. Otherwise, they'll steam instead of roast.
- For extra crispiness, flip the squash halfway through roasting.
Pro Tips
Step-by-Step Instructions
1. Preheat Oven
Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper for easy cleanup.
2. Prep the Squash
Carefully peel the butternut squash with a vegetable peeler. Cut it in half lengthwise, scoop out the seeds, and cut the flesh into 1-inch cubes. Aim for uniform pieces so they cook evenly.
3. Season the Squash
In a large bowl, toss the squash cubes with olive oil, chopped sage, salt, and pepper until well coated.
4. Arrange on Sheet
Spread the seasoned squash in a single layer on the prepared baking sheet. Make sure the pieces aren't touching – this ensures they roast rather than steam.
5. Roast Until Tender
Roast for 20 minutes, then flip the cubes with a spatula. Continue roasting for 10-15 more minutes, until the squash is fork-tender and the edges are golden brown and caramelized.
6. Add Parmesan
Sprinkle the grated Parmesan over the hot squash and return to the oven for 2-3 minutes, just until the cheese melts.
7. Serve Warm
Transfer the roasted squash to a serving dish, garnish with extra fresh sage if desired, and serve immediately.
Delicious Variations
Maple-Bourbon Glaze
Drizzle with 1 tablespoon maple syrup and 1 tablespoon bourbon before roasting for a sweet, boozy twist.
Spicy Harissa
Toss with 1 tablespoon harissa paste instead of sage for a smoky, spicy kick.
Balsamic Glaze
After roasting, drizzle with balsamic glaze and sprinkle with toasted pecans for extra crunch.
How to Store Roasted Butternut Squash with Sage and Parmesan
Refrigerator
Store leftovers in an airtight container in the fridge for up to 4 days.
Freezer
Freeze in a single layer on a baking sheet, then transfer to a freezer-safe bag for up to 3 months.
Reheating
Reheat in a 400°F (200°C) oven for 5-7 minutes until heated through and crispy. You can also microwave, but the edges won't be as crisp.
Frequently Asked Questions
Q: Can I use frozen butternut squash?
Yes, you can use frozen butternut squash, but thaw and pat it dry before roasting to avoid excess moisture. You may need to add a few extra minutes of roasting time.
Q: How do I peel butternut squash easily?
Use a sharp Y-shaped vegetable peeler and work from top to bottom. You can also microwave the whole squash for 2-3 minutes to soften the skin, making it easier to peel.
Q: Can I make this ahead of time?
Yes, you can roast the squash up to 2 days ahead and reheat before serving. Add the Parmesan just before serving to keep it fresh.
Q: What can I substitute for sage?
If you don't have sage, use fresh thyme or rosemary – both work beautifully with squash. Dried herbs also work, but use about 1 teaspoon.
