How to Make Oven Roasted Sweet Potato Cubes with Onion and Rosemary Recipe
Step 1: Preheat and Prep
Start by preheating your oven to a toasty 400°F. To get those sweet potato cubes and onions roasting to crispy perfection, place two baking sheets in the oven while it heats. This little trick makes sure your veggies sizzle the moment they hit the hot metal, giving you that glorious golden crust we all love.
Step 2: Toss with Oil, Herbs, and Seasoning
Next, grab a large bowl and combine your chopped sweet potatoes and sweet onion pieces. Drizzle in the olive oil and toss everything together until every cube and slice is glistening. Sprinkle on your chopped fresh rosemary, kosher salt, and freshly ground black pepper, then mix again. This step is where flavor infuses right into the veggies, setting the stage for a deeply aromatic and savory roast.
Step 3: Roast to Perfection
Carefully spread your coated sweet potatoes and onions across the preheated baking sheets, making sure they’re in a single layer without crowding. Pop the sheets into the oven and roast for about 25 to 30 minutes. Halfway through, rotate the sheets and flip the cubes and onions to ensure even browning. Keep an eye out because depending on your dice size, the roasting time might vary. The goal is tender, caramelized veggies with just the right amount of crisp edges.
Step 4: Final Seasoning and Serve
Once roasted, remove the baking sheets from the oven and give everything a final seasoning touch with additional salt and pepper to taste. These last sprinkles of seasoning’ll elevate every bite, releasing the sweet and savory balance that makes this Oven Roasted Sweet Potato Cubes with Onion and Rosemary Recipe so special.

Creative Ways to Present
Try serving these roasted sweet potato cubes and onions over a bed of fluffy quinoa or farro for a wholesome bowl meal. They also work beautifully as a warm salad topping or tossed with a handful of toasted nuts and crumbled feta for added texture and flavor complexity.
Make Ahead and Storage
Storing Leftovers
Place any leftovers in an airtight container and refrigerate for up to 4 days. The potatoes hold their flavor well and make a fantastic ready-to-go side for quick weeknight meals.
Freezing
You can freeze the roasted sweet potato cubes and onions in a single layer on a baking sheet first, then transfer to a sealed bag or container. Frozen portions last up to 3 months. When ready to enjoy, simply thaw overnight in the fridge.
Reheating
Reheat leftover roasted sweet potatoes in a 375°F oven for about 10-12 minutes to regain their crisp edges. Alternatively, a quick sauté in a hot skillet with a little oil also brings back that fresh roasted texture and flavor.
FAQs
Can I use dried rosemary instead of fresh?
Yes, you can use dried rosemary if fresh isn’t available, but reduce the amount by about half since dried herbs are more concentrated. Add it during the oil and seasoning toss so it rehydrates and flavors the potatoes well.
What if I don’t have sweet potatoes?
While sweet potatoes give this recipe its signature taste, you can substitute with regular Yukon Gold or red potatoes. The flavor will be less sweet but still delicious when paired with onions and rosemary.
How do I make sure the sweet potatoes don’t get mushy?
Cut your sweet potatoes into uniform cubes and avoid overcrowding the baking sheet. Giving them enough room allows hot air to circulate, promoting crispiness rather than steaming.
Can I add other vegetables?
Absolutely! Carrots, parsnips, or even brussels sprouts would complement these flavors nicely. Just adjust the roasting time for vegetables that take longer or shorter to cook.
Is this recipe vegan and gluten-free?
Yes, this recipe is naturally vegan, dairy-free, and gluten-free, making it a versatile side dish suitable for many dietary preferences.
