Refrigerate filled homemade macarons unless your specific recipe or product instructions say they're shelf-stable. The filling determines storage: an unfilled almond shell and a macaron filled with cream or fruit need different treatment.
What goes where?
| What you have | Storage starting point |
|---|---|
| Unfilled, fully cooled shells | Keep airtight; follow the shell recipe's room-temperature or freezing instructions. |
| Ganache or buttercream filling | Refrigerate unless the exact recipe or maker gives another validated storage method. |
| Cream cheese, cream, curd, or fresh fruit filling | Refrigerate and follow the filling's storage limit. |
| A purchased box | Use its storage label and use-by date, including any instructions about freezing. |
For perishable fillings, keep the fridge at 40°F (4°C) or below. USDA advises refrigerating perishable food promptly and not leaving it out for more than two hours, or one hour above 90°F. That limit includes time spent on a serving table. See USDA's refrigeration guidance.
How long do macarons last?
There isn't one safe storage time for every filling. For example, King Arthur's French macaron recipe gives its filled macarons up to one week in the fridge or one month in the freezer. Ladurée gives its own macarons a four-day window, counted from box preparation and shipping.
Those are instructions for different products, not interchangeable promises. Use the guidance for the macarons you actually made or bought, and label the container with the filling and date.
Refrigerating and serving
Let baked shells cool before filling. Put the assembled macarons in a rigid, airtight container so they don't pick up fridge odors or get crushed.
Some recipes benefit from a refrigerated rest before eating; our popcorn macarons rest overnight. Take out only the portion you're serving and allow it to soften briefly, staying within the perishable-food time limits above.
Can you freeze macarons?
Yes, when the filling and recipe allow it. Pack cooled macarons securely in an airtight freezer container, date it, and use the recipe's freezing limit. Thaw perishable filled macarons in the fridge, with the container closed. USDA recommends refrigerator thawing for perishable foods.
