Pro-tip #1: Seek out Lacinato kale (the one pictured below). Not only is the flavor more mild and less bitter, but the leaves are flat, so it dries out evenly in the oven. Lacinato kale chips blow curly kale chips out of the water. Trust me.
Pro-tip #2: Kale chips are super fragile, so don’t chop it into pieces before baking (unless you want kale chip powder). I bake the whole leaf (minus the stem) and break into bite sized pieces after baking.
Pro-tip #3: Save the stems for another recipe. I’ll either chop them up and saute like onions when starting a tomato sauce or stew, or put them (still whole) in a freezer bag for the next time I make homemade broth.
