To make homemade stuffing from your bread cubes simply sauté a diced onion and a few stalks of celery in a ¼ cup (half stick) of butter, add the cubes, and add enough broth to moisten them, 2 cups should do. Now bake at 350 for 30 minutes.
There, you just made delicious stuffing from scratch!
1 (1 lb) loaf of bread, cut into ½-inch cubes (roughly 10 cups of bread cubes)
2 Tablespoons olive oil (or your liquid/melted fat of choice)
