Freezing Herb Cubes: Preserve Fresh Herbs in Ice Cube Trays
Fresh herbs wilt quickly – as cubes in the freezer, they keep their flavor for weeks.

A bunch of parsley often only lasts a few days in the fridge. Then it goes limp – and ends up in the trash. Herb cubes solve that: you portion the whole bunch at once and get flavor out of the freezer for weeks.
It fits perfectly with freezing meal prep: small building blocks that instantly upgrade sauces and soups.
Oil or water?
| Medium | Ideal for | Advantage | Note |
|---|---|---|---|
| Oil (olive/canola) | pesto-style, sautéing, dressing base | protects aroma, no freezer burn | count the calories |
| Water or broth | soups, stews, curries | neutral, cheap | some loss of aroma possible |
| Butter (melted/warm) | herb butter for steak, potatoes | tasty finish | melt quickly |
Step by step
- Wash the herbs, spin them dry well (see salad spinner), chop finely.
- Fill the ice cube tray: herbs into each cavity, then cover with oil or water.
- Freeze until solid. Then move the cubes to a freezer bag and label.
- When needed, add 1–2 cubes straight to the pan, pot or dressing.
Label bags with herb and date. Best quality is about two to three months.
Which herbs work?
- Very good: parsley, cilantro, dill, basil, chives, thyme, rosemary, sage.
- Great in oil: chop garlic and chili in too – ready-made flavor cubes.
- Better kept fresh: very delicate leafy greens and microgreens – they need the crunch.

FAQ
Can I freeze herbs without liquid?
Yes, but they dry out more easily. Oil or water protects them better.
Do frozen herbs taste like fresh?
For cooking, very much so. As a garnish on the plate, fresh is still better.
Can I mix different herbs?
Yes – e.g. an "Italian mix" of basil, oregano and thyme.
How do I stop the smell from taking over the ice?
Use a tray with a lid or move the cubes to a bag promptly.
Does this work with leftover chopped herbs?
Yes: put chopped herb leftovers straight into the tray instead of throwing them away.
