The allure of the French macaron is undeniable. Its delicate shell, vibrant color, and smooth, flavorful filling make it a coveted treat. However, achieving macaron perfection is a notoriously challenging feat. One of the most common frustrations bakers encounter is a chewy macaron, instead of the desired crisp shell and soft, airy interior. Let’s dive deep into the potential culprits behind chewy macarons and how to troubleshoot them.
Understanding the Ideal Macaron Texture
Before we troubleshoot, it’s important to define the ideal macaron texture. A perfectly baked macaron should have a smooth, glossy shell that gives way to a slightly crisp exterior. The interior should be soft, airy, and slightly chewy, but not gummy or excessively dense. The “foot,” the ruffled edge at the base of the macaron, should be well-defined and evenly developed. This balance of textures is what makes the macaron so delightful. When macarons are overly chewy, it indicates an imbalance in the recipe, technique, or baking process.
Common Culprits: Analyzing the Ingredient Ratios
The success of macarons relies heavily on precise ingredient ratios. Even slight deviations can drastically affect the final product.
Almond Flour Finesse
The quality and texture of your almond flour are paramount. Coarsely ground almond flour can lead to a grainy, chewy macaron. Look for blanched almond flour that is finely ground and consistently sized.
Sifting the almond flour is crucial to remove any larger particles and ensure a smooth batter. Even “fine” almond flour can contain larger pieces that need to be sifted out. Discarding these larger particles will contribute to a smoother, more delicate macaron.
Consider the moisture content of your almond flour. If your flour has absorbed moisture from the air, it can impact the final texture. To combat this, you can try toasting your almond flour lightly (be careful not to burn it) before grinding it with the powdered sugar. This helps to dry it out and improve its consistency.
The Sugar Situation
The type and amount of sugar used also play a significant role. Powdered sugar (also known as icing sugar or confectioners’ sugar) is a blend of granulated sugar and cornstarch. The cornstarch content helps to absorb moisture and prevent clumping, but too much cornstarch can result in a dry, chewy macaron.
Ensure your powdered sugar is fresh and not overly clumpy. Lumps can indicate that it has absorbed moisture. Sifting the powdered sugar alongside the almond flour is equally important to ensure a smooth batter.
Granulated sugar is used in the Italian or Swiss meringue method to create a stable meringue. The ratio of sugar to egg whites in the meringue is crucial for achieving the desired structure and preventing chewiness. Insufficient sugar can lead to a weak meringue, while excessive sugar can make the macarons too dense and chewy.
Egg White Essentials
Egg whites are the backbone of the macaron structure. How you prepare and incorporate them can significantly affect the final texture.
Ageing egg whites is a common practice among macaron bakers. Separating the egg whites a day or two in advance and storing them, covered, in the refrigerator allows some of the moisture to evaporate. This results in a more stable meringue that can hold its shape better.
Whipping the egg whites to the correct stage is critical. Over-whipping can result in a dry, crumbly meringue, while under-whipping can lead to a flat, runny batter. You’re looking for stiff, glossy peaks that hold their shape when the whisk is lifted.
The temperature of your egg whites can also affect the meringue. Room temperature egg whites tend to whip up faster and achieve greater volume than cold egg whites. However, some bakers prefer using cold egg whites for their perceived stabilizing effect. Experiment to see what works best for you.
Mastering Macaronage: Achieving the Right Consistency
Macaronage is the technique of folding the meringue into the almond flour and powdered sugar mixture. This process is crucial for achieving the correct batter consistency. Over-mixing or under-mixing the batter are frequent causes of chewy macarons.
The goal of macaronage is to deflate the meringue slightly and create a smooth, flowing batter that resembles lava. This “lava-like” consistency is essential for achieving the characteristic smooth shell and feet of the macaron.
Over-mixing the batter incorporates too much air, leading to a batter that is too thin and spreads excessively during baking. This can result in flat, chewy macarons.
Under-mixing the batter, on the other hand, leaves the meringue too stiff and the batter too thick. This can prevent the macarons from developing a proper foot and result in a dense, chewy texture.
The proper macaronage technique requires patience and practice. Use a flexible spatula and gently fold the dry ingredients into the meringue, scraping the sides of the bowl as you go. Continue folding until the batter flows smoothly and forms a ribbon when dropped from the spatula.
Baking Bliss or Baking Blunders: Perfecting the Baking Process
Even with the perfect batter, improper baking can lead to chewy macarons. Oven temperature, baking time, and resting time are all critical factors.
Oven Temperature Temptation
An inaccurate oven temperature is a common culprit behind baking problems. Ovens can fluctuate in temperature, so investing in an oven thermometer is essential for accurate readings.
Baking macarons at too low a temperature can result in a flat, chewy texture. The macarons may not develop a proper foot, and the interior may remain undercooked.
Baking macarons at too high a temperature can cause them to crack or burn. The exterior may become too hard, while the interior remains chewy.
Experiment with your oven to find the optimal temperature for baking macarons. Most recipes recommend a temperature between 275°F and 325°F (135°C and 163°C).
Baking Time Trials
The ideal baking time for macarons depends on the size of the macarons, the oven temperature, and the humidity. Overbaking can dry out the macarons and make them chewy. Underbaking can leave the interior undercooked and gummy.
Start by following the baking time recommended in your recipe, but keep a close eye on the macarons. They are usually done when the feet are well-risen and the shells are set but still slightly soft.
The “wiggle test” is a helpful way to determine doneness. Gently touch the top of a macaron shell. If it wiggles excessively, it needs more time. If it feels firm and doesn’t move much, it’s likely done.
Resting Period Pointers
Allowing the piped macarons to rest on the baking sheet before baking is a crucial step in developing the characteristic smooth shell and foot. This resting period allows a skin to form on the surface of the macarons.
If the macarons are not allowed to rest long enough, they may crack during baking. The skin prevents the macarons from expanding too quickly, allowing the foot to develop properly.
The resting time depends on the humidity. In humid environments, it may take longer for the skin to form. You can use a fan to help speed up the drying process. The surface should be dry to the touch before baking.
Humidity’s Havoc: Dealing with Environmental Factors
Humidity can wreak havoc on macaron making. High humidity can make it difficult for the skin to form on the macarons during the resting period and can also affect the meringue stability.
Baking macarons on a humid day can be challenging, but not impossible. Try increasing the resting time, using a fan to help dry the macarons, and adjusting the oven temperature slightly.
If you live in a humid climate, consider investing in a dehumidifier for your kitchen. This can help create a more stable environment for macaron making.
Storage Solutions: Preserving Perfection
Proper storage is essential for maintaining the texture and flavor of macarons. Improper storage can lead to chewy macarons.
Store macarons in an airtight container in the refrigerator. This will help prevent them from drying out or absorbing moisture from the air.
Macarons can be stored in the refrigerator for up to a week. Allow them to come to room temperature before serving.
Macarons can also be frozen for longer storage. Wrap them individually in plastic wrap and then place them in an airtight container. Thaw them in the refrigerator before serving.

Final Thoughts: The Pursuit of Macaron Mastery
Making perfect macarons is a journey, not a destination. Don’t be discouraged by setbacks. Every batch, whether successful or not, provides valuable learning experiences. By understanding the science behind macaron making and carefully controlling the ingredients, technique, and baking process, you can overcome the challenge of chewy macarons and achieve macaron mastery. Practice makes perfect, so keep experimenting, refining your technique, and enjoying the process of creating these delightful treats. Remember, even seasoned bakers encounter challenges, so be patient with yourself and celebrate your progress along the way. Consistent practice, meticulous attention to detail, and a willingness to learn from mistakes are the keys to unlocking the secrets of the perfect French macaron.
Why are my macaron shells chewy instead of crispy?
A chewy macaron shell typically points to an excess of moisture or insufficient baking. Underbaking prevents the internal structure from fully setting, leading to a soft, sticky texture after cooling. Additionally, humidity can significantly impact the drying process, preventing the formation of the necessary thin skin on the surface, which is crucial for achieving the signature crispy shell.
Consider extending the baking time by a minute or two, or slightly increasing the oven temperature (by a few degrees) to ensure the macarons are fully cooked through. Also, pay close attention to the drying stage. If you live in a humid environment, using a dehumidifier or drying the macarons under a fan can help reduce moisture absorption and promote proper shell formation.
What role does humidity play in chewy macarons?
Humidity is a significant enemy of perfect macarons because it interferes with the drying process. The characteristic “skin” that forms on the surface of the macaron before baking is essential for creating the crispy shell and hollow “foot.” High humidity prevents this skin from forming properly, causing the shells to remain sticky and absorb moisture during baking, resulting in a chewy texture.
Even slight increases in humidity can affect the outcome. On humid days, you might need to extend the drying time significantly or even consider using a dehumidifier in your kitchen. Alternatively, some bakers have success placing the macarons in an oven with only the light on to create a warm, dry environment. Experimentation is key to find what works best in your specific climate.
Could overmixing the macaron batter cause chewy shells?
Yes, overmixing the macaron batter, also known as macaronage, can contribute to chewy macaron shells. The goal of macaronage is to deflate the meringue slightly to create a batter that flows smoothly from the spatula in a ribbon. Overmixing breaks down the meringue too much, resulting in a runny batter that spreads excessively during baking and bakes unevenly.
The overmixed batter loses its structure and becomes difficult to control, often leading to flat, dense shells that lack the desired crispy exterior and instead turn out chewy. Be careful to stop mixing when the batter reaches a lava-like consistency, flowing slowly and smoothly. Test the batter’s consistency frequently during macaronage to avoid overmixing.
Why are my macaron shells still chewy after resting overnight?
If your macaron shells remain chewy even after resting overnight, the primary cause is likely underbaking or insufficient drying. Even with proper drying, underbaked macarons will continue to absorb moisture from the filling and the surrounding environment, resulting in a persistent chewiness that doesn’t resolve with rest.
Review your baking time and oven temperature to ensure the macarons are thoroughly cooked. If you’re confident in your baking process, revisit the drying stage. Even if they felt dry before baking, they may not have been adequately dried for your specific environment. Experiment with longer drying times or methods to reduce humidity around the macarons before baking.
Does the type of almond flour I use affect the texture?
Yes, the type of almond flour significantly impacts the texture of your macarons. Coarsely ground almond flour will result in gritty, uneven shells and can contribute to a chewy texture due to uneven moisture distribution. Almond flour with a high moisture content can also lead to problems.
Always use finely ground almond flour, also known as almond meal or almond flour (blanched). Sifting the almond flour with powdered sugar before incorporating it into the meringue is crucial for removing any larger particles and ensuring a smooth, consistent batter. Using a high-quality, dry almond flour is essential for achieving the desired crisp exterior and delicate interior.
Can the oven temperature impact macaron chewiness?
Absolutely, the oven temperature plays a critical role in achieving the perfect macaron texture. An oven that’s too cool will cause the macarons to spread excessively and bake unevenly, leading to a chewy texture. Conversely, an oven that’s too hot can cause the shells to brown too quickly on the outside while remaining undercooked on the inside.
Accurate oven temperature is vital. Use an oven thermometer to verify your oven’s accuracy and adjust the temperature accordingly. Experiment with small adjustments to find the sweet spot for your oven and macaron recipe. A stable and consistent oven temperature is crucial for the successful formation of the macaron’s signature foot and crisp shell.
Could incorrect egg white aging contribute to chewy macarons?
While not the most direct cause, improperly aged egg whites can indirectly contribute to chewy macarons. Aging egg whites helps to reduce their moisture content, which can lead to a more stable meringue. If the egg whites are not aged properly, or if they are aged in a humid environment, they may retain too much moisture.
Excessive moisture in the meringue can affect the overall batter consistency and interfere with the formation of the crisp shell. Ideally, egg whites should be aged uncovered in the refrigerator for 24-72 hours. Always ensure they are stored in a clean, dry container to prevent them from absorbing unwanted moisture from the environment.
