How Long to Wait Before Refrigerating Meal Prep: Expert Guidelines and Tips

If you’re always on the go and strive to maintain a healthy lifestyle, you’ve probably heard of meal prep. Meal prep involves preparing meals in advance to save time, money, and ensure nutritious meals are available throughout the week. However, did you know that proper storage is crucial for maintaining the quality and freshness of meal prep meals?

Refrigerate your meal prep within two hours of cooking for safety and quality. If the temperature is above 32°C (90°F), do so within one hour to prevent bacterial growth. To cool food quickly, use ice baths, stir frequently, and monitor with a food thermometer. Store meal prep in an organized fridge set to 4°C (40°F) or below to maintain freshness and safety.

In this blog post, I’ll provide you with expert guidelines and tips on how long to wait before refrigerating meal prep to ensure they stay fresh and safe to eat.

How Long Should You Wait to Put Your Meal Prep Meals in the Fridge?

To ensure both safety and quality, it’s important to refrigerate your meal prep within two hours of cooking. If the ambient temperature is above 32°C (90°F), reduce this time to one hour. This precaution helps prevent your food from entering the “temperature danger zone”—a range between 4°C (40°F) and 60°C (140°F) where bacteria can multiply rapidly. According to the FDA (U.S. Food & Drug Administration), food left in this temperature range for too long can harbor dangerous levels of bacteria, increasing the risk of foodborne illnesses. To keep your meals safe, make sure to refrigerate them promptly.

Cooling Cooked Food Quickly

Properly cooling your meal prep before storing it in the fridge is essential to maintain its quality and prevent bacterial growth. Here are some effective tips:

Quick Cool Your Meals in an Ice Bath: Submerge your meal containers in an ice bath to cool them down rapidly. This method is particularly useful if you don’t have time to wait for your meals to cool naturally.
Stir Cooked Food Frequently: Stirring your cooked meals frequently helps them cool down faster, especially for soups and stews.
Monitor the Temperature: If you want to make sure not to leave your meal prep out of the fridge for longer than necessary, you can use a food thermometer to monitor the temperature. As soon as your thermometer hits 21 ° C (70° F), pop your meal prep in the fridge.

Storing Cold Meal Prep Safely

Once your meal prep is cooled, storing it properly in the fridge is crucial to maintain freshness and safety. Here are some tips for safe storage:

Check the Temperature of Your Fridge: Ensure your fridge is set to 4°C (40°F) or below. If your fridge doesn’t have a built-in thermometer, purchase an inexpensive appliance thermometer and place it in the coldest part of the fridge.
Don’t Pack Your Fridge Too Full: For optimal performance, ensure there’s enough space for air to circulate. Avoid overpacking your fridge to allow cold air to move freely.
Use the Top of Your Fridge for Meal Prep: The top and middle shelf of your fridge should be reserved for ready-to-eat foods, ready meals and packaged foods, leftovers, and prepared salads. While raw food should be stored in the bottom coldest part of the fridge. In this way, harmful bacteria cannot transfer from the raw food to the cooked food. I personally like to store meal prep on the middle shelf (second top shelf), and condiments and packaged foods on the top shelf. This because the second top shelf is a little bit colder then the top shelf, which helps meal prep last better.
Pack Your Lunch in a Cooler: When transporting your lunch to work, use a cooler bag with an ice pack to keep your meal cold.
Thaw Frozen Meals in the Fridge: Plan ahead for thawing meals. A frozen meal can take several hours to thaw in the fridge. Put the lunch you want to eat the next day in the fridge the previous night, and the dinner you want to eat the same day in the fridge on the same morning. Avoid thawing meals on the counter. This method is not considered a safe thawing method, according to the USDA (U.S. Department of Agriculture).

Additional Tips for Meal Prep Storage

Divide into Smaller Portions: Larger portions take longer to cool, creating an environment for bacteria to grow. Divide your meals into smaller containers to ensure quick and even cooling.
Label Your Containers: Clearly label your meal prep containers with the date and contents. This helps you keep track of freshness and ensures you consume older meals first.
Use Quality Containers: Invest in high-quality, airtight containers that are microwave and freezer-safe. This keeps your meals fresh longer and prevents spills or contamination.
Utilize Reusable Silicone Bags: Store chopped vegetables in reusable silicone bags to keep them fresh and save space in your fridge.

Reheating Meal Prep Safely

Reheating your meal prep correctly is essential to ensure it’s safe to eat. Always heat your food to at least 75°C (165°F) to kill any bacteria that may have developed during storage. Here are some tips for safe reheating:

Use a Food Thermometer: Check the internal temperature of your food to ensure it has reached a safe temperature.
Stir and Rotate Food: If using a microwave, stir and rotate your food midway through heating to avoid cold spots where bacteria can survive.
Cover Your Food: Use a microwave-safe cover to retain moisture and ensure even heating.

Conclusion

Meal prepping is an excellent way to save time, stay on track with your health goals, and enjoy nutritious meals throughout the week. By understanding the importance of proper storage and following these expert guidelines and tips, you can ensure your meal prep remains safe, fresh, and delicious.
