Instructions

  1. Step 1: Preheat oven to 425°F (220°C). Toss 12 oz cubed sweet potatoes with 1 tbsp olive oil, 3 smashed garlic cloves, 1/4 tsp sea salt, and 1 tsp chopped rosemary in a large bowl until evenly coated.
  2. Step 2: Spread potatoes in a single layer on a parchment-lined baking sheet, ensuring pieces don’t overlap.
  3. Step 3: Roast for 25-30 minutes, flipping halfway through, until potatoes are golden brown at the edges and tender when pierced with a fork.
  4. Step 4: Remove from oven and let rest for 5 minutes, allowing flavors to meld and garlic to soften into the potatoes.
