Cut the broccoli lengthwise so the florets attached to the long stalks are 1 to 2 inches wide.
Bring 1 inch of water to a boil in a Dutch oven fitted with a steamer basket.
Steam the broccoli until tender, 5 to 7 minutes.

Meanwhile, whisk flour and 1/4 cup milk in a small bowl until smooth.
Heat the remaining 3/4 cup milk in a saucepan over medium-low heat until steaming.
Whisk in the flour mixture; cook, whisking, until thickened, 2 to 4 minutes.
Remove from the heat; add cheese, salt, pepper and nutmeg (if using).
Drizzle over the broccoli.
