The first time I tried drying basil, I hung it in a bundle in my kitchen window — the Pinterest method. It turned black and moldy in four days. Turns out basil is one of the hardest herbs to dry, and most of the advice online skips the part where different herbs need totally different methods.

Which herbs dry well (and which do not)

Woody herbs are easy: rosemary, thyme, oregano, sage, bay leaves, marjoram. These have low moisture content and sturdy leaves that hold their flavor when dried. Hang them in bundles or lay them on a screen in a dry, dark place with airflow. One to two weeks and they crumble off the stem.

Soft herbs are trickier: basil, cilantro, parsley, mint, dill, tarragon. They have high water content and delicate leaves. Hang-drying basil almost always ends in mold. For these, you want speed — the faster they dry, the more flavor and color they keep.

The fast method for soft herbs

Lay leaves in a single layer on a paper towel on a plate. Microwave in 30-second bursts, checking between each burst. Most herbs are dry in 60 to 90 seconds total. They should be crispy but still green. If they start browning, you went too long. Let them cool, then crumble into a jar. This method preserves more flavor than any slow-drying technique because it minimizes oxidation time.

For larger batches, a food dehydrator at 95 degrees Fahrenheit for 4 to 6 hours works perfectly. Oven-drying works too: lowest setting (ideally 170 F or lower), door cracked open with a wooden spoon, 2 to 4 hours. But watch them — ovens are inconsistent at low temperatures.

Freezing as an alternative

For basil and cilantro specifically, I do not bother drying anymore. I chop them, pack them into ice cube trays, cover with olive oil or water, and freeze. Pop out one cube when you need fresh herb flavor in a soup or sauce. Frozen herbs lose some texture but keep almost all their flavor. They will not work for garnish, but for cooking, frozen cubes beat dried every time.

Storage

Dried herbs lose flavor from light, heat, and air. Store them in airtight glass jars in a dark cabinet — not above the stove, not on a windowsill. Whole dried leaves keep their flavor longer than crumbled ones. Crush them just before using. Properly dried and stored herbs last about a year before the flavor fades noticeably.
