A cross between a French fry and hashbrowns, these crispy roasted sweet potato cubes make a deliciously healthy addition to dinner, salads, and everyday side dishes.
Oven-Roasted Cubed Sweet Potatoes
Recipes like these roasted sweet potato cubes remind me not to underestimate the power of the oven. You just need to add a little heat and some oil to transform your vegetables and starches into something amazing!
Roasting caramelizes the natural sugars in sweet potatoes and gives them a soft middle with a crispy-edged texture. Then, you can serve these tasty cubes as a side, a topping, and so much more. Yummy!
If roasting is not your go-to method for cooking veggies, try these sweet potato cubes and you’ll never look back! I love roasting all kinds of vegetables and they always turn out perfectly cooked and delicious.
Ingredients
Sweet potatoes are extremely versatile and taste amazing with any number of spices and seasonings, so you can choose your favorite flavor profile. Here’s what you’ll need to turn sweet potatoes into delicious roasted cubes:
- Sweet potatoes: cut them into 1-inch cubes.
- Olive oil: makes the potatoes crispy and golden.
- Salt: enhance the sweet potato flavor.
- Seasonings: you can toss potatoes in Roasted Vegetable Seasoning, Homemade Taco Seasoning, a mix of cinnamon and salt, or combine garlic powder with salt and black pepper.
How to Prep and Cube Sweet Potatoes
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.
To prep sweet potatoes for the oven, rinse, lightly scrub them, and pat them dry. Peeling them is optional. 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
Cut the sweet potatoes into cubes, preheat the oven, and line a large baking sheet with parchment paper. - Toss with oil and salt
Drizzling the sweet potatoes with olive oil makes them crispy and golden brown, so don’t omit it. Also, season with salt and your choice of seasonings before roasting. Toss to combine. - Roast
You want to spread the potatoes in an even layer onto the baking sheet. Crowding them can lead to soggy potatoes. Roast for 30 minutes or until the edges are golden brown and the centers fork tender.
Short on time? Try air-frying sweet potato cubes instead!
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.
Below are the cook times for 1-inch cubed sweet potatoes at different temperatures.
| Oven Temp | Time |
|---|---|
| 350 F | 40 minutes |
| 375 F | 35 minutes |
| 400 F | 30 minutes |
| 425 F | 25 minutes |
Baking Tips for Sweet Potato Pieces
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.
What Else to Roast with Sweet Potatoes
At 400F and 35 minutes, you can roast several other ingredients with sweet potatoes, making it an excellent “starch” option for my sheet pan dinners.
Proteins to Roast with Sweet Potatoes
Below you’ll find a chart of different cuts of meat to roast at 400F with sweet potatoes. While chicken thighs can take longer than 25 minutes, you can place them on a separate sheet pan and baking rack. Or remove the potatoes and veggies from the baking sheet once they are done and let the chicken finish cooking.
| Protein | Cook Time |
|---|---|
| Boneless, skinless chicken thighs | 25 mins or internal temp 165F |
| Boneless, skinless chicken breasts | 35 mins or internal temp 175F |
| Salmon fillets | 10-12 mins or internal temp 145F |
| Smoked chicken sausage | 24 mins |
Vegetables you can Roast with Crispy Sweet Potatoes
You can season and toss these veggies onto the same sheet pan as the sweet potatoes but try to keep them separate since some veggies may finish before the potatoes do.
- Brussels sprouts, halved or quartered (35 minutes)
- broccoli florets (20 minutes)
- red cabbage (about 25 minutes)
- beets (about 25 minutes)
- cauliflower florets (20-25 minutes)
What to Serve with Roasted Cubed Sweet Potatoes
Once they’re out of the oven, you can top them over this Winter Salad, dip them with hummus for a quick snack, or serve them as a side with Healthy Turkey Burgers or with Pan Seared Chicken Breasts.
You can also roast the sweet potato cubes on the sheet pan with Sausage & Peppers or serve on the side of Bacon & Spinach Breakfast Frittata.
