Meanwhile, place potatoes in a medium pot with enough salted water to cover by 2 inches. Bring to a boil and cook until tender, 12-15 minutes. Drain and return potatoes to pot; cover to keep warm.

While potatoes cook, heat a drizzle of oil in a large pan over medium-high heat. Add onion and cook, stirring occasionally, until lightly browned and softened, 8-10 minutes. Sprinkle with 1 tsp sugar (2 tsp for 4 servings). Stir in stock concentrate and 2 TBSP water (¼ cup for 4); season with salt and pepper. Cook until jammy, 2-3 minutes more. Turn off heat; transfer to a small bowl. Wash out pan.
