With brown sugar, vinegar, and liquid aminos, these sweet potatoes are the best balance of savory and sweet. You know they are perfectly cooked when they are tender but not falling apart.
Preheat oven to 375°F. Whisk together brown sugar, vinegar, liquid aminos, and salt in a large bowl. Add sweet potatoes; toss well to coat. Spread mixture evenly in a 13- x 9-inch baking dish; dot with butter.
Roast in preheated oven 25 minutes. Stir sweet potatoes; roast until fork-tender and glazed, 20 to 25 minutes, stirring gently every 8 minutes. Remove from oven. Garnish with sesame seeds.
