A fast and easy side dish, your family will love these sweet and caramelized balsamic roasted sweet potatoes, cauliflower and onions.

A lot of people tell me they tend to eat the same vegetable side dish night after night – usually steamed green beans or broccoli. While delicious, I always recommend eating a variety of foods all year long for maximum nutrition and health benefits.

If there’s one thing I’ve learned over the years when it comes to eating vegetables, it’s that roasting is almost always the best way to create maximum flavor with very minimal effort.

Balsamic Roasted Sweet Potatoes, Cauliflower & Onions couldn’t be easier to make or tastier. Feel free to mix and match with any vegetables you have on hand such as parsnips, Brussels or kohlrabi. The options are endless.
As the vegetables roast the natural sugars caramelize created a sweet, smoky and super flavorful side dish that no one can resist.
Your fork is waiting.
Can vegetables be roasted in advance and reheated?
Yes, they absolutely can be reheated although they will be slightly softer than having just come out of the oven. Of course, you could always reheat in the oven to get them crispy again.

Balsamic Roasted Sweet Potatoes & Cauliflower
Ingredients
- 2 medium sweet potatoes (peeled and cubed)
- 1 small head cauliflower (cut into florets)

This was super easy to make and absolutely delicious! I stirred the veggies in the middle of cooking to make sure they got more evenly browned and caramelized. I didn’t have any fresh herbs on hand, unfortunately, but I sprinkled them with a little cayenne pepper and it was perfect!
That sounds amazing! So glad you liked it!!
I just made this and it was delicious. Thanks for the tip about spreading the vegetables out really well to get a good roast on them!

Made the full recipe and it was very good. But even better was the frittata I made the next day with 3 cups of leftovers! Added thyme, fresh basil, some Parmesan and goat cheese.
