I bake sourdough bread fairly regularly and for me, there is no better crouton than Sourdough Croutons I make from the bread that is a little dry. I chop it up and warm some olive oil and butter in a saute pan. Toss in your sourdough bread cubes and toast them up. I add a little bit of sea salt and granulated garlic while they are toasting. I think they are perfect when they have a nice crispy outside and the inside is still soft. I add them to soups (like this Roasted Butternut Squash Soup) and salads to add a little bit of crunch.
