What makes this veggie frittatas different from all the others?

I make it in a casserole dish.  There, I’ve said it.  After years of make frittatas in a skillet, I changed my approach to using a casserole dish and I’m loving the ease of the recipe and I really like that I can prepare it in advance and just bake it off when I’m ready to serve.

Don’t get me wrong, you can use this same recipe to start your frittata in a skillet on the stove.  After cooking your veggies on the stove, just add the egg mixture and pop the skillet into the oven.  Not a big deal.

BUT, I really like that in this recipe, I cook the veggies and add to a casserole dish.  I add the egg mixture and top with cheese. Then, I can put it in the oven when I’m ready to bake it off.  I also like the presentation better AND I can put any leftovers (right in the baking dish) into the fridge for later.  I know, this is just a preference, but also another option for you.

Can you freeze leftover frittata?

Yes, you can freeze frittata, and it can be stored in the freezer for up to 3 months. To freeze, allow it to cool completely, then wrap it tightly and store it in an airtight container or freezer bag.   This makes it a great option for a make-ahead breakfast.
Here’s a more detailed guide on how to freeze any leftover frittata:
  • Cool Completely: Ensure the frittata is completely cooled before attempting to freeze it.
  • Wrap Tightly: Wrap the frittata in at least one layer of storage wrap and one layer of aluminum foil to prevent freezer burn.
  • Transfer to Airtight Container: Place the wrapped frittata into an airtight container or freezer-safe bag.
  • Freeze: Store the frittata in the freezer for up to 3 months.
  • Thaw: Thaw the frittata in the refrigerator overnight.
  • Reheat: Reheat the frittata in the microwave or oven until warmed through.  I’ll wrap a piece of the frittata in papertowel and put in the microwave for 10-15 seconds.
