Prepare and bake gluten-free sourdough bread if making from scratch.
Preheat oven to 350.
Melt butter in a cast iron skillet or pan.
Cut bread into one-inch slices, then into one-inch chunks.
Spread bread cubes onto a parchment-lined baking sheet and pour about half of the melted butter over the bread pieces. Toss together.
Bake for twenty minutes, stirring halfway in between so the bread doesn’t burn. You want it to get nice and toasty.
Dice celery and onions, then place into pan with the remaining melted butter over medium-low heat.
Sauté until they are a little soft, around 5-10 minutes.
Chop fresh thyme and sage, then add to veggies. Or sprinkle in dried herbs.
Add salt and pepper.
Pull the toasted bread out of the oven.
In a large bowl, whisk together one cup of chicken broth and eggs.
Add toasted, gluten-free bread and the sautéed vegetables to the bowl, mix, and allow the liquid to be absorbed by the bread for a few minutes. If the mixture seems dry, add another 1/2 cup to one cup of broth.
Pour the stuffing back into the cast iron skillet (or baking dish) and bake for 25-35 minutes, until it starts to turn golden brown.
