• 1¼ cups milk, plus more if necessary
• 1 teaspoon ground ginger
• ¾ teaspoon sea salt
• ¼ teaspoon freshly ground black pepper
• ¼ cup fresh sage leaves, for garnish
• ⅔ cup whole rolled oats
• ½ cup pecans, plus more for garnish
• ½ cup walnuts, plus more for garnish
• 1 garlic clove

Direction

1. Preheat the oven to 425°F. Line a baking sheet with foil and brush an 9x13-inch baking dish with olive oil.
2. Use a fork to poke a few holes into the sweet potatoes. Place on the baking sheet and roast until very tender, about 60 minutes.
3. Make the crumble topping: In a food processor, place the oats, pecans, walnuts, garlic, maple syrup, olive oil, thyme, rosemary, salt, and pepper and pulse until just combined. Remove and set aside.
4. Scoop the cooked sweet potato flesh out of the skins and place in a food processor. Add the olive oil, milk, ginger, salt, and pepper and process to combine. Spread the mixture into the baking dish.
5. Sprinkle with the crumble topping, additional nuts, and sage leaves. Drizzle with olive oil and bake for 20 minutes, or until the topping is browned and crisp.
