A cross between a French fry and hashbrowns, these crispy roasted cubed sweet potatoes make a deliciously healthy addition to dinner, salads, and everyday side dishes.
It’s recipes like this that remind me not to underestimate the power of the oven. Add a little heat and some oil to transform your vegetables and starches. Roasting caramelizes the natural sugars in sweet potatoes and gives them a soft middle with a crispy-edged texture.
You’ll be craving these roasted sweet potatoes at least once a week.
Roasting Cubed Sweet Potatoes
It’s incredible how a simple process, like roasting, can elevate everyday sweet potatoes into a top-notch in flavor and texture side dish. Before I share the recipe, here are helpful tips so they cook into orange gems that everyone will be grabbing:
Use parchment paper
Not only does this prevent the potatoes from sticking to the baking sheet, but it makes less clean up for you.
Layer evenly
We want the potatoes to caramelize and get a little browned. Crowding the pieces too close together will cause them to steam and become soggy.
Give it a toss
Halfway through baking, carefully use a spatula to toss the potato pieces, so they brown evenly.
Don’t skimp on the oil
Even though we use parchment, the oil helps the potatoes brown and crisp up. You don’t need much just a tablespoon or two.
Seasonings
Sweet potatoes are extremely versatile and taste amazing with any number of spices and seasonings. You can toss them in:
- Roasted Vegetable Seasoning
- Homemade Taco Seasoning
- cinnamon + salt
- garlic powder + salt + black pepper
How to Prep a Sweet Potato for Roasting
There is no need to boil the sweet potatoes before roasting. It’s unnecessary and creates more work for you. The oven gives enough heat to cook them through to achieve a soft center and crisp up on the edges.
Here’s how to prep cubed sweet potatoes for the oven:
- Rinse and lightly scrub the potatoes
- Pat dry
- Peel, if you wish (it’s optional)
- Cut into 1-inch cube
How to Cube a Sweet Potato for Roasting
The size to cut the sweet potato into cubes depends on how crispy you like them. Smaller cubes, about ½ to ¾-inch, will be crisper like breakfast potatoes, while larger cubes, 1-inch, are tender but still have golden brown edges.
To easily cut them, use a chef knife to slice a small piece from the potato lengthwise, then lay it flat. This way, it won’t roll around.
How to Roast Cubed Sweet Potatoes
Grab a large sheet pan, those ingredients, and let’s make some crispy roasted sweet potatoes.
- Prep
Preheat the oven to 400F and line a large baking sheet with parchment paper. - Toss with oil and salt
Place the sweet potato cubes onto the baking sheet and drizzle with olive oil. Season with salt and your choice of seasonings. Toss to combine. - Roast
Spread the potatoes in an even layer onto the baking sheet and roast for 30 minutes or until the edges are golden brown and the centers fork tender.
How to Prep Roasted Cubed Sweet Potatoes Ahead
You can prep sweet potatoes before roasting on meal-prep day and after being roasted for a heat-and-serve option.
Without roasting:
To prep sweet potatoes ahead of time without roasting; after dicing, refrigerate the sweet potato cubes in an airtight container filled with water for up to 2 days. The water prevents them from drying out and turning brown.
Before cooking, drain the water and pat the potatoes thoroughly dry with a clean kitchen towel to prevent them from steaming.
After roasting:
I like having roasted sweet potato cubes around as an easy starch to top over salads or to serve alongside dinner. They can be cooked entirely ahead of time and refrigerated for up to 4 days. Just give them a quick reheat in the microwave or in the oven at 400F for 10 minutes or until crisp and heated through.
How Long to Roast Cubed Sweet Potatoes
At 400F, these 1-inch sweet potato cubes take about 30 to 35 minutes to cook. While you can roast these at a higher or lower temperature, 400F is the magic number since the potatoes brown in time with cooking.
