Slice the baked bread into small cubes (think croutons.)
1 Loaf Gluten-free Bread of Choice
Lay the cubes onto a baking tray lined with parchment paper.
Bake the gluten-free bread in a 350-degree oven for about 20 minutes or until the pieces of bread start to feel dry and crunchy.
Transfer the bread cubes to a food processor and pulse them to turn the bread cubes into crumbs.
Continue to pulse the bread crumbs until desired texture is achieved.
Allow the breadcrumbs to cool before putting them away to store for later use.
To Season (if desired)
Once the breadcrumbs are made, add the spices to them in the food processor and pulse one or two more times to break up the spices before storing them.
Notes
Can you make bread crumbs without a food processor?Yes, you can make bread crumbs without a food processor. It is a little bit more work, but it can be done.
Place your dried bread pieces into a ziplock bag.
Seal the ziplock bag and place it flat on the counter.
Roll a rolling pin over the pieces to break them up.
If you find that your bread is flattening more than it is breaking apart into crumbs, you need to dry it out more and then repeat.
Tip for making gluten-free bread crumbs that last.If the crumbs still feel (like bread), try dehydrating them. Don't worry; you don't need a dehydrator to do this. I use this technique just when I want my gluten-free graham crackers to be extra crispy and make them last longer or when I'm making my gluten-free graham cracker crust.If you've processed your bread crumbs and they still feel soft, do this.
Reduce the oven temperature to 225 degrees.
Place the bread crumbs back onto the parchment-lined baking sheet.
Bake the bread crumbs in the oven for about 10-15 minutes at the lower temperature.
After they have baked, check the texture again.
Repeat for another 5 minutes at a time until you've reached your desired dryness.
