Activate the Yeast: In a small bowl, combine the warm milk and sugar. Sprinkle the active dry yeast over the top and stir gently. Let it sit for about 5 to 10 minutes until it becomes frothy and bubbly, which indicates the yeast is active and ready to help your rolls rise.
Mix the Dough: In a large mixing bowl or the bowl of a stand mixer, combine the flour and salt. Add the yeast mixture, the softened butter, and the egg. Use a dough hook or a sturdy spoon to mix until a soft dough begins to form and pulls away from the sides of the bowl.
Knead the Dough: Knead the dough on a lightly floured surface for about 8 to 10 minutes by hand, or 5 minutes in a stand mixer on medium-low speed. The dough should be smooth, elastic, and slightly tacky to the touch but not sticking to your fingers.
First Rise: Place the dough in a lightly greased bowl and cover it with a clean kitchen towel. Set it in a warm, draft-free spot and let it rise for about 60 to 90 minutes. You want the dough to double in size, which is essential for that light Christmas morning texture.
Shape the Rolls: Gently punch down the risen dough to release air bubbles. Divide the dough into 12 equal portions. Roll each piece into a smooth ball and place them in a greased 9 by 13 inch baking pan, leaving a little space between each roll so they can expand.
Second Rise: Cover the pan with the towel again and let the rolls rise for another 30 to 45 minutes. They should look puffy and be touching each other slightly. Preheat your oven to 375 degrees F during this time.
Bake the Rolls: Place the rolls in the oven and bake for 18 to 20 minutes. They should be a beautiful golden brown on top. While they bake, whisk together the melted butter, minced garlic, garlic powder, and chopped parsley in a small bowl.
Apply Garlic Butter Glaze: As soon as the rolls come out of the oven, brush the garlic butter mixture generously over the hot tops. The heat will slightly cook the garlic and allow the butter to soak into the crust, creating a savory finish that is perfect for your Christmas feast.
