This recipe for keto breadsticks is gluten-free as long as the spices you use don't have any gluten in them. Most dried spices are gluten-free, but it is important to read the labels and know where they are packaged to determine if there is any chance of cross-contamination. Spice blends like premixed rubs can sometimes contain wheat or barley, so it is especially important to read the labels when purchasing and using these types of spice blends.
