How to Store or Freeze Your Breakfast Bites
Allow the egg white breakfast bites to cool completely after baking. This helps prevent condensation, which can make them soggy.
Place the cooled bites on a baking sheet lined with parchment paper, ensuring they are not touching each other. Freeze them for about 1-2 hours or until they are solid. This step, known as flash freezing, prevents them from sticking together when stored.
Once frozen, transfer the bites to an airtight container or a resealable freezer bag. Label the container or bag with the date to keep track of their freshness.
For optimal taste and texture, consume the frozen egg white breakfast bites within 2-3 months. While they can be stored longer, they may lose some quality over time.
To reheat, remove the desired number of bites from the freezer. You can either thaw them in the refrigerator overnight or reheat them directly from frozen.
If reheating from frozen, preheat your oven to 350°F (175°C). Place the bites on a baking sheet and cover them loosely with aluminum foil to prevent them from drying out. Bake for 10-15 minutes or until heated through.
Alternatively, you can reheat the bites in the microwave. Place them on a microwave-safe plate and cover with a damp paper towel. Microwave on high for 1-2 minutes, checking and turning them halfway through to ensure even heating.
For added convenience, consider storing individual portions in separate containers. This makes it easy to grab a quick, nutritious breakfast on busy mornings.
If you prefer a fresh taste, you can also store the egg white breakfast bites in the refrigerator for up to 4 days. Keep them in an airtight container to maintain their moisture and flavor.
When storing in the refrigerator, reheat the bites in the microwave for about 30-60 seconds or until warmed through.
