Meanwhile, bring a large pot of salted water to a boil. Add the spinach and cook just until wilted, about 1 minute. Transfer to a large colander and drain extremely well, pressing firmly on the spinach, or wrap in a clean kitchen towel and squeeze to remove as much excess liquid as possible. Coarsely chop the spinach and set aside.
In a large skillet over medium-low heat on the stove, melt the butter. Add the shallots and garlic and cook until very tender, 7 to 8 minutes, stirring occasionally. Add the flour and cook until golden brown, about 1 minute, stirring constantly. Increase the heat to medium; gradually add the half-and-half and stir until the mixture thickens, 2 to 3 minutes. Stir in the spinach and nutmeg and cook until heated through, 1 to 2 minutes. Remove from the heat, add the cheese, and stir until melted. Cover to keep warm.
