Herb-Roasted Sweet Potatoes and Onions

This morning, as I was rummaging through my fridge, I realized I had a couple of sweet potatoes and an onion that needed to be used up. That’s when I remembered this simple yet flavorful dish that never fails to impress. It’s perfect for those days when you want something delicious without too much fuss.

Ingredients

• 2 medium sweet potatoes, peeled and cubed
• 1 large onion, sliced into half-moons
• 2 tablespoons olive oil
• 1 tablespoon fresh rosemary, chopped
• 1 tablespoon fresh thyme leaves
• A good pinch of salt and freshly ground black pepper

Instructions

1. Preheat your oven to 400°F (200°C). This ensures everything cooks evenly and gets those crispy edges we love.
2. In a large bowl, toss the sweet potatoes and onions with olive oil, rosemary, thyme, salt, and pepper until everything is well coated. Tip: If you’re short on time, you can do this directly on the baking sheet to save on dishes.
3. Spread the mixture in a single layer on a baking sheet. Crowding the pan will steam the veggies instead of roasting them, so give them some space.
4. Roast for 25-30 minutes, stirring halfway through, until the sweet potatoes are tender and the onions are caramelized. Tip: For extra caramelization, let them sit for a minute or two longer at the end.
5. Serve hot. These herb-roasted sweet potatoes and onions are incredibly versatile—toss them into salads, serve as a side, or even top with a fried egg for a hearty breakfast.

Absolutely love how the sweetness of the potatoes pairs with the savory onions and herbs. The edges get slightly crispy, while the inside stays soft and flavorful. It’s a dish that feels fancy but is honestly so easy to make.

Maple Glazed Roasted Sweet Potatoes with Caramelized Onions

Back when I first stumbled upon this recipe, I was skeptical about pairing sweet potatoes with onions, but let me tell you, the combination is a game-changer. It’s become my go-to side dish for family gatherings, and today, I’m sharing it with you.

1. Preheat your oven to 400°F (200°C). This ensures your sweet potatoes get that perfect roast.
2. Toss the sweet potato cubes with 1 tbsp olive oil, salt, and pepper on a baking sheet. Spread them out so they’re not touching for even roasting.
3. Roast for 25 minutes, then flip the potatoes for uniform browning. Tip: Don’t skip the flipping; it’s key for that crispy exterior.
4. While the potatoes roast, heat the remaining 1 tbsp olive oil in a skillet over medium heat. Add the onions and a pinch of salt, stirring occasionally until they’re golden and caramelized, about 15 minutes.
5. Drizzle the balsamic vinegar over the onions in the last 2 minutes of cooking for a tangy depth of flavor.
6. Once the potatoes are done, toss them with the maple syrup and caramelized onions. Return to the oven for 5 minutes to let the glaze thicken. Tip: Keep an eye on them to prevent burning.
7. Serve hot. The contrast between the sweet glaze and the savory onions is unreal. Try topping with a sprinkle of goat cheese for an extra layer of flavor.
