How to Roast Butternut Squash and Sweet Potatoes

Roasting butternut squash and sweet potatoes comes down to three things: even chunks, high heat, and giving them room to breathe on the pan.
 
When you learn how to roast butternut squash and sweet potatoes properly, you get that deep golden caramelization that makes them taste almost like candy.
 
Here’s the basic method for how to roast butternut squash and sweet potatoes that you can follow every time.
 

1. Prep and Cube Both Vegetables Evenly

Start by peeling your butternut squash and cutting it into cubes about one inch thick.
 
Peel the sweet potatoes too, then cut them into cubes the same size as the squash so everything roasts at the same rate.
 
Even cubes are the biggest factor in how to roast butternut squash and sweet potatoes without one burning while the other stays raw.
 
Toss the cubes in a large bowl and set them aside while you preheat the oven.
 

2. Toss With Oil and Seasonings

Drizzle olive oil over the cubes and toss until every piece is lightly coated.
 
Oil helps the edges crisp up and keeps the insides tender, which is a key part of how to roast butternut squash and sweet potatoes that taste rich rather than dry.
 
Season with salt, black pepper, and a little garlic powder or smoked paprika for warmth.
 
A pinch of cinnamon or nutmeg works beautifully here too since both vegetables love a touch of sweet spice.
 

3. Spread Them in a Single Layer

Spread the cubes on a large baking sheet in a single layer, leaving space between each piece.
 
If they’re crowded, they’ll steam instead of roast, and that’s the fastest way to ruin how to roast butternut squash and sweet potatoes.
 
Use two baking sheets if you need to.
 
This is one of those small steps that makes a huge difference in how to roast butternut squash and sweet potatoes with crispy golden edges.
 

4. Roast at 425°F and Flip Halfway

Roast at 425°F (220°C) for about 25 to 35 minutes.
 
Flip the cubes with a spatula at the halfway mark so both sides get that caramelized color.
 
They’re done when a fork slides in easily and the edges are browned and slightly crisp.
 
That’s really all there is to how to roast butternut squash and sweet potatoes.
