With gluten free bread, some of the “hard work” of making regular bread (kneading) is no longer an issue. So to make your bread , you’ll be mixing the ingredients together (a stand mixer is great for this), dumping that “dough” (really more like a thick batter) into a bread pan, let it rise for a reasonable time, then put it in the oven to bake. You have to be there to pull the bread out of the oven at the right time.
Meanwhile if you use a bread machine, you’ll be dumping your ingredients in, the machine will mix for you, and bake for you. Nice part here is that you aren’t tied to the timing of everything; the machine will let the bread rise, turn on the heat at the right time to bake it, turn off the heat. So you throw the ingredients in right before bed, and have a loaf of bread waiting in the morning. Or start a loaf of bread and then go mow the lawn or watch a movie or whatever you want to do.
If you do get a bread machine, make sure to get one that has a GF setting, or has programable modes so that you can skip the knead/rise cycles, as the kneading cycles used for normal bread won’t work well with GF bread.
