Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F. Toss 2 lbs cubed sweet potatoes, 2 medium cut red onions, 3 tbsp olive oil, 6 smashed garlic cloves, 2 rosemary sprigs, 1 tsp sea salt, and 1/2 tsp black pepper in a single layer on a parchment-lined sheet pan.
  2. Step 2: Roast for 25 minutes, stirring halfway through, until vegetables are tender and edges are caramelized and golden brown.
  3. Step 3: Increase oven temperature to 450°F and roast for 5 more minutes until vegetables develop deep brown spots and release a sweet, nutty aroma, stirring once to ensure even browning.
  4. Step 4: Remove rosemary sprigs and garlic cloves, then transfer to a serving dish. Season with an additional pinch of sea salt and black pepper to taste before serving.
