Roasted Sweet Potato and Black Bean Salad

Roasting sweet potatoes with ground cumin brings out their natural sweetness while creating tender, lightly caramelized edges. Combining those warm cubes with cooked black beans and crisp red onion creates a satisfying, balanced dish that comes together with minimal prep. Because it does not rely on a heavy dressing, the warm spices and olive oil coat the ingredients naturally. It works equally well served straight from the mixing bowl while still warm or set aside to enjoy at room temperature.
Why this one works
- Roasting at high heat creates rich caramelization on the sweet potato cubes.
- Ground cumin provides a warm, savory contrast to the sweet roasted potatoes.
- Crisp diced red onion adds sharp bite and textural balance to tender beans.
- Flexible enough to serve either immediately warm or at room temperature.
- Straightforward preparation using simple pantry and produce staples.

What you’ll need
- 2 cups (400g) cubed sweet potatoes Cut into uniform bite-sized cubes so they cook evenly throughout the 25-minute roast.
- 1 cup (180g) cooked black beans Rinse and drain well before combining so excess liquid does not dilute the seasoned oil.
- 1/2 cup (75g) red onion diced Dice finely to distribute its sharp crunch evenly without overpowering individual bites.
- 2 tablespoons (30ml) olive oil Coats the potatoes to facilitate even browning and bloom the ground cumin during roasting.
- 1 teaspoon (5g) cumin Tossed directly with the raw potatoes to toast and deepen in flavor in the oven.
- 2 cups (300g) potatoes, cubed
