Learn how to use the Duralex Freshbox rectangular set for efficient meal prep, from stacking to reheating, with practical storage tips.
Quick Answer
For efficient meal prep, use the Freshbox rectangular set to portion, store, and reheat meals, leveraging its stackable, tempered glass design.
Why Rectangular Freshbox Works for Meal Prep
The Freshbox set includes three rectangular containers in different sizes, making it easy to portion meals for the week. The tempered glass is durable and safe for reheating, and the stackable design saves fridge and cabinet space.
One trade-off: the set doesn't include lids with airtight seals, so for long-term storage of liquids, consider using additional cling film or a separate lid system.
Step-by-Step Meal Prep with Freshbox
- Choose Your Portions: Decide which meals you'll prep and assign a container size for each. Use the largest for main dishes, medium for sides, and smallest for snacks or sauces. Check that each container is filled to at least 75% to maximize space and minimize air exposure.
- Cool Food Before Sealing: Let cooked food cool to room temperature before placing it in the container. This prevents condensation, which can make food soggy and reduce freshness. Never put hot food directly into the glass; thermal shock can crack tempered glass.
- Seal and Label: If your lids don't provide an airtight seal, press a piece of cling film over the rim before closing. Write the date and contents on a label or with a dry-erase marker. Always label with the prep date to track freshness and avoid forgotten leftovers.
- Stack and Store: Stack the containers in the fridge or freezer, placing heavier ones at the bottom. The rectangular shape maximizes shelf space. Leave a little space between stacked containers for air circulation to help maintain even temperature.
- Reheat Safely: Remove the lid before reheating in the microwave or oven. The tempered glass can handle heat, but always use a microwave-safe cover or paper towel to prevent splatters. Check that the container is not cold when placed in a hot oven; let it come to room temperature first.
