Oven Baked Sweet Potato Cubes
These Oven Baked Sweet Potato Cubes are one of the easiest and most flavorful sweet potato recipes you’ll ever make. Tossed in olive oil, fresh lemon juice, and a blend of spices like paprika, cumin, and garlic powder, these sweet potatoes turn out crispy on the edges and perfectly caramelized inside. Naturally sweet and full of flavor, they make a delicious side dish for holiday dinners or a quick weeknight meal. Best of all, everything is roasted on one pan, so cleanup is super simple.

Easy and low effort: This is the perfect side dish for busy nights or holiday meals. Just toss everything on a sheet pan and let the oven do the work.
Minimal cleanup: Since it’s baked on one pan, cleanup is quick and stress-free.
Super versatile: You can easily switch up the spices or add a touch of brown sugar or maple syrup for a sweet twist.
Ingredients
- Sweet Potatoes: For this recipe, I used 3 medium-sized sweet potatoes, but you can also use 2 large ones or 5 to 6 smaller sweet potatoes. Make sure to peel them before cutting into cubes.
- Oil: I prefer using olive oil for its rich flavor, but you can easily substitute with avocado oil or coconut oil depending on what you have on hand.
- Dijon Mustard: Dijon mustard adds a subtle tang that complements the sweetness of the potatoes. You can also use yellow mustard or whole grain mustard if that’s what you have available.
- Lemon Juice: Fresh lemon juice is a must for this recipe. It adds a burst of brightness and brings out all the savory and sweet flavors.
- Spices: Sweet potatoes can be quite bland, so I love using a bold spice blend. For this version, I mix together salt, garlic powder, Italian seasoning, dried parsley, cumin, paprika, and white pepper to add layers of flavor and a little warmth.

How To Bake Sweet Potatoes
Step 1. Preheat your oven to 450°F.
Step 2. In a small bowl, whisk together the salt, garlic powder, Italian seasoning, dried parsley, cumin, paprika, and white pepper. Set aside.
Step 3. Peel the sweet potatoes and cut them into 1-inch cubes. Add them to a large mixing bowl.
Step 4. Add olive oil, lemon juice, Dijon mustard, and the spice mix to the sweet potatoes. Toss everything together until the sweet potatoes are evenly coated.
Step 5. Spread the sweet potatoes in a single layer on a baking sheet. Bake for 30 to 45 minutes, or until the edges are golden and the sweet potatoes are fork-tender. Make sure to flip the sweet potatoes around halfway through with a fork or spatula.

Oven Baked Sweet Potato Cubes FAQ
Can I air fry the sweet potatoes?
Yes, you can absolutely air fry them instead of baking. Just add the seasoned sweet potato cubes to your air fryer basket and cook at 400°F for 15 to 18 minutes, shaking halfway through, until they’re crispy and fork-tender.
What can I use instead of white pepper?
If you don’t have white pepper on hand, regular black pepper works just as well. It adds a slightly bolder kick but still pairs perfectly with the other spices.
How can I make these sweet potatoes more sweet and savory?
To bring out more sweetness, add a tablespoon of brown sugar, maple syrup, or honey when seasoning the sweet potatoes. For extra savory flavor, increase the amount of paprika or toss in some chili flakes for a spicy kick.
