By the end of this article, you’ll know exactly how to keep your Costco macarons fresh and delicious. Whether you’re planning to eat them within a few days or save them for a special occasion weeks later, you’ll have a clear understanding of how long Costco macarons need to be refrigerated.
What Are Costco Macarons?
Costco is renowned for offering a wide range of high-quality, reasonably priced products, and their French macarons are no exception. These little colorful pastries come in a variety of flavors, such as vanilla, chocolate, pistachio, raspberry, and seasonal flavors like salted caramel or lemon. Made by top-quality pastry brands like Tipiak, Costco macarons are as close to an authentic French patisserie experience as you’ll find in a warehouse club. But with such delicate desserts, you may wonder how long Costco macarons need to be refrigerated to maintain their texture and flavor.
Macarons are made with a combination of almond flour, powdered sugar, egg whites, and various flavorings, filled with buttercream, ganache, or fruit jams. The precise balance of moisture, air, and ingredients is critical to their texture, which is why their storage becomes so important. Knowing how long Costco macarons need to be refrigerated ensures you enjoy them at their best.
Why Does Proper Storage Matter?
Because macarons are so sensitive to their environment, proper storage is critical. Costco’s packaging keeps them fresh on store shelves, but once you bring them home, you must handle them carefully to maintain that perfect texture. Left out too long or improperly stored, macarons can become unappetizing very quickly.
- Room temperature: At room temperature, macarons tend to lose their texture in just a few hours, as they’re exposed to air and moisture.
- Refrigeration: Refrigeration slows down this process, keeping macarons fresher for up to 7 days.
- Freezing: If you want to store them for longer, freezing them is your best bet. Properly frozen macarons can last up to 3 months.
Understanding how to store Costco macarons properly can make all the difference between a crispy, delicious treat and a stale, disappointing one. Storing them properly in an airtight container, as well as knowing when to refrigerate and when to freeze, will ensure that your macarons last as long as possible while retaining their original flavor and texture.

Do Costco Macarons Need to Be Refrigerated?
Yes, Costco macarons do need to be refrigerated if you want them to last more than a day or two. Macarons are made from delicate ingredients, and their fillings often contain perishable elements like butter or cream. Leaving them at room temperature for too long can cause them to spoil, lose their structure, or dry out.
Why Refrigeration is Necessary for Macarons
Refrigeration slows down the degradation of the macaron shell and filling, helping to preserve the texture and flavor. When stored properly in the fridge, Costco macarons can stay fresh for up to 7 days. Here’s what happens to macarons as they sit at room temperature:
- Loss of crispness: The macaron shell begins to soften as it absorbs moisture from the air.
- Filling spoilage: Cream- or butter-based fillings can spoil if left unrefrigerated for too long.
- Staleness: Macarons left at room temperature for over a day can become stale, losing their chewy texture.
Placing macarons in the fridge prevents these issues. By refrigerating them, you maintain the macaron’s balance of textures—the crisp exterior and the soft, flavorful interior.
However, refrigeration needs to be done correctly. Storing macarons improperly in the fridge can lead to condensation, making them soggy. The key to refrigerating Costco macarons successfully lies in airtight containers.
Best Practices for Refrigerating Macarons
When refrigerating macarons, always use an airtight container to protect them from moisture and odors. The container keeps the macarons from absorbing flavors from other foods in the fridge, like onions or garlic. Macarons are delicate, and any strong odor can affect their taste.
Here’s a step-by-step guide for refrigerating macarons:
- Use an airtight container: Always place the macarons in an airtight container. If you’re stacking them, use parchment paper between the layers to prevent them from sticking.
- Store in a stable environment: Keep the macarons in the refrigerator at 36-38°F (2-3°C) for up to 7 days.
- Allow time to adjust: When you’re ready to eat the macarons, remove them from the fridge and allow them to sit at room temperature for about 20-30 minutes before serving.
How Long Should Costco Macarons Be Refrigerated?
When stored correctly, Costco macarons can last in the refrigerator for up to 7 days. However, the freshness and quality of the macarons may start to diminish after the first couple of days.
Here’s a breakdown of what you can expect when refrigerating macarons:
- Days 1-2: The macarons will taste fresh, and the shell will remain crisp. The filling will retain its full flavor.
- Days 3-4: The macarons may begin to soften slightly, but they will still be enjoyable. The shell may lose some of its crispness, but the texture will still be appealing.
- Days 5-7: By this time, the macarons will likely have softened significantly. While they may still be edible, the texture and flavor won’t be as vibrant as they were on the first day.
Refrigerating Costco macarons helps to keep them fresh, but for longer-term storage, freezing them is a better option. Once you pass the 7-day mark, the macarons will likely lose much of their original appeal. If you know you won’t be able to finish them within a week, it’s better to freeze them.
When Should You Freeze Macarons?
Freezing macarons is the best method for preserving their freshness for a longer period. Properly frozen macarons can last for up to 3 months without losing much of their quality. Freezing allows you to enjoy your macarons at a later date while still maintaining their taste and texture.
Refrigeration vs. Freezing: Which Is Better?
Deciding whether to refrigerate or freeze your macarons depends on how quickly you plan to eat them. If you’re planning to enjoy your Costco macarons within a week, refrigeration is sufficient. But if you want to extend their shelf life beyond a week, freezing is the better option.
The Benefits of Freezing Macarons
Freezing macarons preserves their texture and flavor for a much longer time than refrigeration alone. The freezing process helps slow down the natural aging of the macarons, keeping their crisp shells and chewy interiors intact.
Frozen macarons can last up to 3 months without losing their quality. This is an excellent option if you want to keep a stash of macarons on hand for special occasions or just as an occasional indulgence.
To freeze macarons properly, follow these steps:
- Use a freezer-safe, airtight container: As with refrigeration, an airtight container is essential. Place the macarons in a freezer-safe container or freezer bag.
- Layer with parchment paper: If you’re freezing multiple layers of macarons, place a sheet of parchment paper between each layer to prevent sticking.
- Thawing frozen macarons: When you’re ready to enjoy your frozen macarons, remove them from the freezer and allow them to thaw at room temperature for about 30 minutes. Do not microwave or heat them to speed up the process.
While freezing is a great long-term storage solution, it’s important to note that the texture of the macarons might change slightly after being frozen. The shells may be a little softer, and the flavors might not be as intense as when fresh. Still, they will remain a delicious treat.

How to Tell If Your Macarons Have Gone Bad
It’s important to know when your Costco macarons have gone past their prime. Even with proper storage, macarons won’t last forever, and there are a few key signs to watch out for that indicate they’re no longer good to eat.
Signs That Your Macarons Have Gone Bad
- Texture changes: Fresh macarons have a crisp outer shell and a chewy interior. If they feel too dry or soggy, they’ve likely gone bad.
- Strange odors: Macarons that have absorbed the smells of other foods in the fridge or freezer may have an unpleasant taste. If they smell off, they’ve likely been stored improperly or for too long.
- Discoloration: A change in the color of the shell or filling is another sign that the macarons have spoiled. If you notice any discoloration, especially in the filling, it’s best to discard them.
Common Mistakes to Avoid When Storing Costco Macarons
Improper storage is the most common reason macarons go bad prematurely. Here are some common mistakes to avoid when storing Costco macarons:
Mistake 1: Leaving Macarons Out Too Long
Macarons should never be left out at room temperature for more than a few hours. Exposing macarons to the air causes them to dry out, leading to a loss of texture and flavor. Always refrigerate or freeze them if you’re not planning to eat them right away.
Mistake 2: Using the Wrong Containers
Failing to use an airtight container can cause the macarons to absorb moisture from the air, making them soggy. It also leaves them exposed to other odors in the fridge or freezer, which can ruin their taste.
Mistake 3: Storing Macarons Near Strong-Smelling Foods
Macarons are like sponges when it comes to absorbing odors. Storing them near foods with strong smells—such as onions, garlic, or fish—can cause the macarons to take on those flavors. Always store them separately in an airtight container.
Mistake 4: Improper Freezing Techniques
Freezing macarons without using a proper container or stacking them without parchment paper can result in freezer burn or sticking. If you don’t freeze them correctly, the macarons may lose their texture or flavor.
