How to Store Butter Safely on the Counter

Use a butter crock (French butter keeper) or covered butter dish:

A butter crock uses water to create an airtight seal, keeping oxygen out.

A covered dish protects from light and contaminants.

Keep it in a cool, dark spot—not next to the stove or in direct sunlight.

✅ Best practice: Only keep out what you’ll use in 3–5 days. Store the rest in the fridge.
