How Long Does Custard Last in the Fridge?
If you’re wondering how long custard lasts in the fridge, the short answer is:
Custard lasts 3–4 days in the refrigerator when stored properly.
Key details:
- Homemade custard: 2–4 days
- Store-bought custard (opened): 3–5 days

How Long Does Custard Last at Room Temperature?
Custard should never be left out for long.
Safe time at room temperature: 1–2 hours maximum.
After that, harmful bacteria can multiply quickly, increasing the risk of food poisoning.

How Long Does Custard Last in the Freezer?
You can freeze custard, but it comes with trade-offs.
Frozen custard lasts up to 1–2 months, but:

Freezing tips:
- Use airtight containers
- Freeze in small portions
- Thaw slowly in the fridge
