Step 1

Combine water and yeast in the bowl of stand mixer. Stir to combine. Allow to stand for five minutes.

Step 2

While the yeast dissolves, combine the gluten-free flour, granulated sugar, xanthan gum, and salt in a small bowl. Whisk.

Step 3

Add the flour mixture to the yeast mixture. Add the milk, egg, and melted butter. Mix on medium speed until smooth, about three minutes. The dough will be very thick.

Step 4

Scoop dough, about 1/3 cup each, onto a parchment lined baking sheet. Smooth the top of each roll with your fingers. Dip your fingers in cool water before smoothing. Cover pan with greased plastic wrap. Allow rolls to rise until double in size.

Step 5

When rolls have almost doubled in size, preheat oven to 350 degrees F. Remove plastic wrap from pan. Bake rolls until golden brown, about 20 minutes.

Step 6

Remove pan from oven. Brush rolls with melted butter and sprinkle with Kosher salt, if desired. (see note) Allow rolls to cool for about 15 minutes before serving.

Step 7

Rolls are best enjoyed the day they are made. Store leftover rolls wrapped on the counter or place cooled rolls in a freezer bag and freeze for up to two months. Thaw rolls at room temperature overnight.
