Yes, you can! Dried lemon zest is easy to make at home in the oven. You'll need to zest about 10 medium lemons to get the amount of dried zest needed for this recipe. Here's how: Simply grate the peel from your lemons (we like the microplane), spread the peel on a parchment lined baking sheet, and bake at 170˚F to 180˚F until completely dried through, about 30-60 minutes. Pro Tip: Make sure to use only the yellow part of the peel. The white part of the peel ("pith") is bitter and will make the seasoning taste unpleasant.
