Ingredients
- 2 large sweet potatoes, peeled and diced into 1-inch cubes
- 2 medium yellow onions, thinly sliced
- 3 tablespoons olive oil
- 1 teaspoon smoked paprika
- 1 teaspoon fresh thyme leaves
- 2 cloves garlic, minced
- Salt and freshly ground black pepper, to taste
- 1 tablespoon pure maple syrup (optional, to enhance natural sweetness)
- Fresh parsley, chopped (for garnish)

Instructions
- Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper for easy cleanup.
- Toss the sweet potato cubes with 2 tablespoons olive oil, smoked paprika, salt, and pepper in a large bowl until evenly coated.
- Spread the sweet potatoes on one half of the baking sheet in a single layer. On the other half, spread the sliced onions tossed with 1 tablespoon olive oil, minced garlic, thyme, and a pinch of salt.
- Roast for 25-30 minutes, turning the vegetables halfway through, until the sweet potatoes are tender and beginning to caramelize, and the onions are golden and sweet.
- Remove from the oven and immediately drizzle maple syrup and balsamic vinegar over both sweet potatoes and onions. Toss gently to coat and blend flavors.
- Adjust seasonings with extra salt and pepper, if needed. Garnish with chopped fresh parsley for a vibrant finish.
- Serve warm alongside grilled vegetables, quinoa, or your favorite protein substitute for a wholesome, satisfying meal.
Tips for Success
- For an extra layer of flavor, try adding a sprinkle of cumin or coriander before roasting.
- If pressed for time, use a high-quality pre-minced garlic to save prep work.
- Sweet potatoes roast best when cubed evenly – aim for consistent sizing to ensure even cooking.
- Make-ahead tip: Roast the sweet potato and onion mixture a day ahead; reheat gently to maintain texture and freshness.
- To add additional texture, sprinkle toasted pecans or walnuts over the finished dish just before serving.
