Instructions

  1. Step 1: Preheat oven to 400°F (200°C). Toss cubed sweet potatoes with 1 tbsp olive oil, salt, and pepper, then spread in a single layer on a baking sheet. Roast for 25-30 minutes until tender and golden at edges, flipping once halfway.
  2. Step 2: Transfer roasted sweet potatoes to a large bowl. Add butter, maple syrup, cinnamon, nutmeg, and salt. Use a potato masher to mash until mostly smooth, then stir in heavy cream until fully incorporated and mixture is creamy.
  3. Step 3: Continue mashing for 2-3 minutes until no large lumps remain and texture is velvety. Taste and adjust seasoning, adding more salt or maple syrup if needed.
