Lemon Thyme Cookies

Herbs in cookies? Absolutely. Dried lemon thyme brings a subtle citrusy, earthy note to these simple butter cookies that’s unexpected and completely addictive. They taste like a shortbread that wandered through an herb garden.

Cream of tartar gives the crumb a tender, slightly tangy quality that sets these apart from a standard sugar cookie. It also helps the cookies spread evenly and develop those characteristic fine cracks on top.

The dough needs at least 4 hours in the fridge, overnight is even better. Cold dough rolls cleanly into walnut-sized balls without sticking to your hands. It also gives the lemon thyme time to infuse its flavor throughout the butter.

Pro Tips

• Rub the dried lemon thyme between your palms before adding it to the dough. This releases the essential oils and intensifies the flavor.
• Roll the balls evenly for consistent baking. Uneven sizes mean some cookies brown while others are still raw in the center.
• Don’t overbake. Pull them when the edges are just barely golden. They firm up as they cool and overbaked herb cookies taste bitter.
• These are best eaten within 3 days. The herb flavor fades after that.

Variations

• Lavender cookies: Swap the lemon thyme for dried culinary lavender for a floral, Provençal-style cookie.
• Rosemary shortbread: Use finely chopped fresh rosemary instead and add a pinch of flaky sea salt on top before baking.
• Lemon glaze finish: Drizzle cooled cookies with a simple glaze of powdered sugar and fresh lemon juice.
