How to Store Basil - Should You Refrigerate

Basil is one of the most beloved fresh herbs — and one of the trickiest to store. Unlike most herbs, basil is cold-sensitive and actually does better at room temperature than in the refrigerator. Here's everything you need to know about how to store basil correctly.

Should You Refrigerate Basil?

Generally, no — basil prefers room temperature. Basil is a tropical herb that's highly sensitive to cold. Temperatures below 50°F (10°C) cause chilling injury — the leaves turn black and slimy within hours. Most refrigerators run at 35–38°F, which is too cold for basil.

The one exception: if your kitchen is very warm (above 75°F), the fridge door — the warmest part of the refrigerator — may be acceptable for short-term storage.

The Best Way to Store Basil: The Water Jar Method

1. Trim the stems — Cut about half an inch off the bottom of the stems at an angle, just like fresh flowers.
2. Place in a jar with water — Stand the basil upright in a glass jar or the OXO Good Grips GreenSaver Herb Keeper with about an inch of room-temperature water.
3. Cover loosely — Place a loose plastic bag over the leaves to maintain humidity without trapping too much moisture.
4. Keep at room temperature — Store on the counter away from direct sunlight and drafts. Do not refrigerate.
5. Change water every 2 days — Fresh water prevents bacterial growth and keeps stems healthy.

How Long Does Basil Last?

• Room temperature (water jar method): 1–2 weeks
• Refrigerator (fridge door only): 2–3 days (leaves may blacken)
• Frozen (in olive oil): up to 6 months

How to Freeze Basil

Freezing is the best long-term option. Blend fresh basil leaves with olive oil and pour into ice cube trays. Once frozen, transfer cubes to a SPLF Reusable Freezer Bag. Drop directly into pasta sauces, soups, and stir-fries from frozen. Alternatively, blanch leaves briefly, pat dry, and freeze flat on a baking sheet before bagging.

Signs Basil Has Gone Bad
