How to Store or Freeze This Recipe
Allow the zucchini lasagna to cool completely at room temperature before storing. This helps prevent condensation, which can make the dish soggy.
For short-term storage, transfer the lasagna to an airtight container. Refrigerate for up to 3-4 days. Make sure to place a layer of plastic wrap directly on the surface of the lasagna to minimize air exposure.
If you plan to freeze the lasagna, cut it into individual portions. This makes it easier to reheat only what you need. Wrap each portion tightly in plastic wrap, then in aluminum foil to prevent freezer burn.
Place the wrapped portions in a freezer-safe bag or container. Label with the date and contents. The lasagna can be frozen for up to 2-3 months.
When ready to reheat, thaw the lasagna in the refrigerator overnight. This ensures even reheating and helps maintain the texture of the zucchini.
Reheat individual portions in the microwave. Place the lasagna on a microwave-safe plate and cover with a microwave-safe lid or another plate. Heat on medium power for 2-3 minutes, checking and stirring halfway through.
For oven reheating, preheat your oven to 350°F (175°C). Place the lasagna in an oven-safe dish and cover with aluminum foil. Bake for 20-25 minutes, or until heated through. Remove the foil for the last 5 minutes to allow the cheese to become bubbly and golden again.
If you notice any excess liquid after reheating, simply drain it off before serving. This can happen due to the water content in the zucchini.
Enjoy your reheated low carb zucchini lasagna with a fresh side salad or some steamed vegetables for a complete meal.
How to Reheat Leftovers
Oven Method: Preheat your oven to 350°F (175°C). Place the leftover zucchini lasagna in an oven-safe dish. Cover it with aluminum foil to prevent it from drying out. Heat for about 20-25 minutes or until the cheese is bubbly and the lasagna is heated through. Remove the foil for the last 5 minutes to let the top get slightly crispy.
Microwave Method: Place a portion of the lasagna on a microwave-safe plate. Cover it with a microwave-safe lid or a damp paper towel to retain moisture. Heat on medium power for 2-3 minutes, checking halfway through to ensure it heats evenly. If needed, continue heating in 30-second intervals until hot.
Stovetop Method: If you prefer a quicker method, use a non-stick skillet. Place the leftover lasagna in the skillet and cover with a lid. Heat on medium-low, adding a splash of water or marinara sauce to prevent sticking. Heat for about 10 minutes, turning occasionally, until warmed through.
Air Fryer Method: Preheat your air fryer to 350°F (175°C). Place the lasagna in the air fryer basket, ensuring it’s in a single layer. Heat for 5-7 minutes, checking halfway through. This method will give you a slightly crispy top, similar to the oven method.
Toaster Oven Method: If you have a toaster oven, preheat it to 350°F (175°C). Place the leftover lasagna on a toaster oven tray and cover with foil. Heat for about 15-20 minutes, removing the foil for the last 5 minutes to crisp up the top.
