  2. Step 2: Spread the sweet potatoes in a single layer on a rimmed baking sheet lined with parchment paper. Roast for 25-30 minutes, flipping halfway through, until edges are golden and centers are tender.
  3. Step 3: Remove the pan from the oven and immediately sprinkle 1 tsp fresh lemon zest and drizzle 2 tbsp fresh lemon juice over the hot potatoes. Toss gently to combine and serve warm as a nutrient-rich side that supports respiratory health.
