You could buy lemon-pepper seasoning at the store, but this easy-to-make blend tastes so much fresher and will wake up chicken or fish, pasta, or even popcorn.
Zest lemons onto a rimmed baking sheet lined with parchment. Add a sprig of rosemary and/or thyme (if you have it). Spread the zest in an even layer, then bake at 250° until dry, about 15 minutes. Remove the leaves from the herb sprigs, then mix the zest and herbs with black pepper, salt, sugar, and granulated onion. Transfer to a small jar and stash the blend in the spice cabinet, where it will keep for a few months.
