After making these many times, I have learned that allowing the garbanzos to get really dry and then reducing the oven temperature after the initial 15 minutes results in a thoroughly crisp snack with less chance of over-browning. You can even allow the drained beans to rest on a tea towel or a few layers of paper towels on the counter for a couple of hours. Beyond that, wrap and store in the refrigerator until ready to roast.
1can garbanzo beans (chick peas), rinsed, drained, and dried (see above notes)
1tablespoon(14ml) olive oil, plus enough to grease the baking sheet
½teaspoonkosher salt, or to taste
Instructions
Preheat the oven to 400℉.
Place the beans on a well-oiled, rimmed baking sheet. Drizzle with the 1 tablespoon olive oil and toss (I like to use my clean hands) so the garbanzos are evenly coated in oil.
Evenly sprinkle the salt over beans. (I move all the beans together on the baking sheet so that most of the salt goes on them as opposed to the tray. Then slide them back out on the tray.)
Roast at 400℉ for 15 minutes. Reduce the oven temperature to 350℉. Stir the beans and roast in 10-minute increments, stirring after every 10 minutes, until crunchy, approximately 20 minutes more. Depending on oven, you may need to bake another 10 minutes or so. Reducing the oven temperature will make it easier to throughly crisp the beans without burning them. (See notes below for a few helpful hints.)
Notes
Dark-colored pans tend to brown food more quickly than light-colored pans. If you're baking on the former and the beans are getting too dark, turn the oven temperature down 25 degrees.
Once cooled, if you taste your garbanzos and they are not completely crisp, simply return to the 350℉ oven for another 10 minutes or so.
Roast other beans too! As you can read in the accompanying post, I've experimented with a variety of other beans using this method. Butter beans are my favorite. They don't look especially pretty, but they taste great!
