In the same pot over medium heat, add 1 tablespoon of olive oil. Once hot and shimmering, add the shallots, reduce heat to low, and cook, stirring frequently, for 10 minutes until the shallots begin to brown. Sprinkle 1 teaspoon of sugar on top and continue cooking over low to medium-low heat (adjust the heat periodically as they cook) for 10 minutes more until evenly browned. Shallots burn very easily, so keep an eye on them!
