How To Store / Freeze This Recipe
Allow the frittata to cool completely before storing. This helps prevent condensation, which can make the frittata soggy.
For short-term storage, transfer the frittata to an airtight container. You can also wrap individual slices in plastic wrap or aluminum foil to keep them fresh.
Place the container or wrapped slices in the refrigerator. The frittata will stay fresh for up to 4 days.
If you want to freeze the frittata, first cut it into individual portions. This makes it easier to reheat only what you need.
Wrap each portion tightly in plastic wrap, followed by a layer of aluminum foil. This double-layer wrapping helps prevent freezer burn.
Place the wrapped portions in a freezer-safe bag or container. Label it with the date so you can keep track of how long it has been stored.
The frittata can be frozen for up to 2 months. For best results, consume it within this timeframe.
To reheat from the refrigerator, unwrap the frittata and place it on a microwave-safe plate. Heat in the microwave for 1-2 minutes, or until warmed through.
For reheating from frozen, unwrap the frittata and place it on a microwave-safe plate. Microwave on a defrost setting for 2-3 minutes, then heat on high for an additional 1-2 minutes.
Alternatively, you can reheat the frittata in the oven. Preheat the oven to 350°F (175°C), place the frittata on a baking sheet, and cover it with aluminum foil. Bake for 15-20 minutes, or until heated through.
How To Reheat Leftovers
Oven Method: Preheat your oven to 350°F (175°C). Place the leftover frittata on a baking sheet lined with parchment paper. Cover it loosely with aluminum foil to prevent it from drying out. Heat for about 10-15 minutes or until warmed through. This method ensures the vegetables remain tender and the eggs stay fluffy.
Stovetop Method: Heat a non-stick skillet over medium-low heat. Add a small amount of olive oil or butter to the pan. Place the frittata slices in the skillet and cover with a lid. Heat for about 5-7 minutes, flipping halfway through, until the frittata is heated evenly. This method helps maintain the crispy edges of the frittata.
Microwave Method: Place a slice of frittata on a microwave-safe plate. Cover it with a damp paper towel to keep it from drying out. Microwave on medium power for 1-2 minutes, checking halfway through. This is the quickest method, but be cautious as it can sometimes make the eggs rubbery.
Toaster Oven Method: Preheat your toaster oven to 350°F (175°C). Place the frittata on a piece of aluminum foil or a small baking tray. Heat for about 10 minutes or until warmed through. This method is great for small portions and keeps the frittata texture intact.
Steam Method: Place the frittata slices in a steamer basket over simmering water. Cover and steam for about 5 minutes or until heated through. This method helps retain moisture and keeps the vegetables vibrant.
Each method has its own charm, ensuring your roasted vegetable frittata remains delicious and satisfying.
