Best Brioche French Toast

Preheat the oven to 350 degrees F (175 degrees C).

Whisk milk, eggs, vanilla, sugar, nutmeg, and salt together in a bowl.

Heat 1 1/2 teaspoons butter in a skillet over medium heat. Working in batches, dip each slice of brioche bread in the egg mixture and cook in the hot butter until golden, 2 to 3 minutes per side, adding more butter as needed. Transfer French toast to a baking sheet.
