Roasting brussel sprouts and butternut squash together is one of the easiest ways to get a delicious, caramelized side dish with minimal effort.
When you roast brussel sprouts and butternut squash, the high heat brings out their natural sweetness and gives them a crispy, golden-brown exterior.
This combination works beautifully because both vegetables have a similar cooking time when cut to the right size.
If you’ve been wondering how to roast brussel sprouts and butternut squash without ending up with mushy sprouts or undercooked squash, you’re in the right place.
In this post, we’ll walk through exactly how to roast brussel sprouts and butternut squash, the best seasonings to use, and a few tips to get them perfectly tender every single time.
Let’s dive in.
How to Roast Brussel Sprouts and Butternut Squash Perfectly
Roasting brussel sprouts and butternut squash is simple once you know the right temperature, timing, and prep steps.
Here’s how to make it happen.
1. Prep the Vegetables Correctly
Start by preheating your oven to 425°F (220°C).
While it heats, wash and dry your brussel sprouts thoroughly.
Cut off the tough stem ends and slice each sprout in half lengthwise so they roast evenly.
For the butternut squash, peel it, scoop out the seeds, and cut it into cubes about one inch thick.
The key to roasting brussel sprouts and butternut squash together is keeping the pieces roughly the same size.
If your squash cubes are much larger than your sprout halves, the sprouts will burn before the squash softens.
2. Toss With Oil and Seasonings
Spread both vegetables on a large baking sheet in a single layer.
Drizzle with two to three tablespoons of olive oil and toss until everything is well coated.
Season generously with salt, black pepper, and garlic powder.
If you want extra flavor, add a pinch of smoked paprika, dried thyme, or a little maple syrup for sweetness.
When you roast brussel sprouts and butternut squash with the right seasonings, they taste almost like candy.
Just don’t overcrowd the pan because steam will build up and you’ll lose that crispy texture.
3. Roast at the Right Temperature and Time
Slide the baking sheet into the oven and roast for about 25 to 30 minutes.
Flip everything with a spatula halfway through so both sides get that nice golden char.
The brussel sprouts are done when the outer leaves are crispy and dark brown in spots.
The butternut squash should be fork-tender with caramelized edges.
If you roast brussel sprouts and butternut squash at 425°F, you’ll get the best balance of tender insides and crispy outsides.
Lower temperatures around 400°F work too, but they take longer and won’t brown as deeply.
Tips for the Best Roasted Brussel Sprouts and Butternut Squash
A few small adjustments make a big difference when you roast brussel sprouts and butternut squash.
Here are the tips that matter most.
1. Dry the Vegetables Before Roasting
Moisture is the enemy of crispy roasted vegetables.
After washing, pat the brussel sprouts dry with a clean kitchen towel or paper towels.
If there’s water clinging to the leaves, they’ll steam instead of roast.
The same goes for the butternut squash after peeling and cubing.
Dry surfaces equal better browning every time.
2. Give Them Space on the Pan
Use a large rimmed baking sheet, or split the vegetables between two sheets if needed.
When you roast brussel sprouts and butternut squash in a crowded pan, they release moisture and start steaming.
Spread them out so each piece has a little breathing room.
That’s the secret to those crispy, caramelized edges everyone loves.
3. Add a Finishing Touch After Roasting
Once they come out of the oven, you can elevate the flavor even more.
Squeeze fresh lemon juice over the top for brightness.
Sprinkle grated parmesan cheese, toasted pecans, or dried cranberries for extra texture.
A drizzle of balsamic glaze also works wonders.
When you roast brussel sprouts and butternut squash, the finishing touches are what turn a simple side dish into something memorable.
Common Mistakes to Avoid When You Roast Brussel Sprouts and Butternut Squash
Even experienced cooks make a few missteps when they roast brussel sprouts and butternut squash.
Watch out for these.
1. Cutting the Pieces Too Small
Small pieces cook fast and dry out before they develop any caramelization.
Keep your squash cubes around one inch and your sprout halves intact.
That size gives you tender interiors with nicely browned exteriors.
2. Skipping the Midway Flip
If you don’t flip the vegetables halfway through roasting, one side gets all the color while the other stays pale.
A quick toss with a spatula ensures even browning.
It takes ten seconds and makes a huge difference.
3. Using Too Low of a Temperature
Low heat gives you soft, limp vegetables instead of crispy ones.
When you roast brussel sprouts and butternut squash at 425°F, you get that ideal contrast of textures.
Don’t be tempted to drop the temperature just because you’re worried about burning.
Just keep an eye on them during the last five minutes.
So, How Do You Roast Brussel Sprouts and Butternut Squash?
You roast brussel sprouts and butternut squash by preheating your oven to 425°F, cutting both vegetables into similar-sized pieces, tossing them with oil and seasonings, and roasting for 25 to 30 minutes with a flip halfway through.
This method gives you crispy, caramelized brussel sprouts and tender, sweet butternut squash every time.
Whether you serve them as a holiday side dish or a weeknight dinner companion, knowing how to roast brussel sprouts and butternut squash is a skill worth having in your kitchen.
