How Long Does Green Curry Paste Last?
Keeping your aromatic curry base fresh and flavorful in the fridge.
Green curry paste lasts about 3 months in the refrigerator when stored properly.
Green curry paste is a vibrant staple, packed with lemongrass, galangal, and fresh chilies. Because it contains fresh aromatics and often a touch of coconut milk or oil to bind the ingredients, it remains stable but will eventually lose its punch. When kept in an airtight container in the refrigerator, the fats help preserve the flavor for several months. However, once opened, exposure to air can cause the paste to oxidize or develop off-flavors over time. Knowing the signs of degradation ensures your next Thai feast is as vibrant and spicy as intended.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.

Common questions
How long does green curry paste last in the refrigerator?
Green curry paste lasts about 3 months in the refrigerator when stored properly. To maintain freshness, keep it in an airtight container to limit exposure to air.
Can I freeze green curry paste?
Yes! Freezing is an excellent way to preserve green curry paste for 6–12 months. Portioning it into ice cube trays allows for easy measuring and preserves the flavor profile.
Why does my curry paste turn brown?
Oxidation from exposure to air causes the herbs and spices to darken over time, particularly at the surface of the jar. Keeping the lid tightly sealed helps slow this process.
Is it safe to use if it smells a bit 'off'?
Sage's Verdict: If there is any sour, musty, or fermented odor, discard it immediately. Do not risk using it in your cooking if the aroma or appearance has changed significantly.
Keep that jar sealed tight! A little oil and a lot of air-tight storage will keep those flavors vibrant for months.
