Many families debate whether butter should be refrigerated or left on the counter. Some swear by keeping it soft and spreadable at room temperature—just like grandma did. But is it actually safe?
The good news: Yes, real butter can be left out safely for a short time. Butter is mostly fat with very little water, which makes it less likely for bacteria to grow quickly. Salted butter is even more resistant to spoilage.
How long is safe?
- Salted butter: Up to 1–2 weeks on the counter in a covered dish, away from heat and sunlight.
- Unsalted butter: Best kept in the fridge, but can sit out for 2–3 days.
Tips for keeping it fresh:
- Use a covered butter dish or crock to protect it from dust and odors.
- Keep only a small portion out and store the rest in the fridge.
- If the butter smells sour, tastes off, or looks discolored, toss it.
Bottom line: Grandma wasn’t wrong—but to be safe, limit how long butter sits out and store extra sticks in the fridge. That way, you get the best of both worlds: spreadable butter and no risk of wasting it.
