Peel and chop 3 pounds sweet potatoes into chunks and cook them in a large pot with lightly salted boiling water until they are fork-tender (about 15 minutes).Drain them and let them steam out for 5 minutes.
Put them in a large bowl with ⅓ cup brown sugar, ¼ cup vegan butter, 1 tablespoon vanilla extract, 1 teaspoon cinnamon, ⅛ teaspoon nutmeg, ½ teaspoon salt, and ⅛ teaspoon black pepper.Mash with a potato masher, hand mixer, or immersion blender until combined.
Preheat oven to 375°F or 190°C. Grease a 9 x 13-inch casserole dish with vegan butter.Transfer mashed sweet potatoes to your casserole dish and flatten it with a spatula.Now, sprinkle with½ cup pecan nuts (chopped), then cover with the crumble topping.For the topping, add ½ cup rolled oats, ½ cup all-purpose flour, ⅓ cup brown sugar, ½ cup vegan butter (fridge-cold and diced), ½ teaspoon cinnamon, and ⅛ teaspoon salt to a food processor and pulse a few times until combined.
Bake at 375°F or 190°C for 15 to 25 minutes or until golden brown and crisp on top.Let cool down for some minutes before serving; the topping gets crispier as it cools.
