Tips and Tricks to Making the Best Egg Casserole

Ingredients for an Egg Casserole

Egg Casserole’s are one of those things you really can’t go wrong with.  The ingredients listed in this recipe aren’t the end all of an egg casserole.  You can modify the ingredients to add virtually anything.

Most egg bakes are savory.  Having said this, you’ll want to put ingredients that are on the salty side, like cheeses, olives, spinach, onions, mushrooms, herbs, and spices. Yes, I said cheeses (plural). You can put more than one, don’t stop there.  Cheeses like feta, parmesan, cheddar, brie, gouda, etc.

And, if you want to add a meat, go ahead.  Some of the best meat products to put in a this easy egg casserole are bacon, prosciutto,  sausage, or chorizo.

In fact, for an egg bake you can pretty much scour your refrigerator and put everything but the kitchen sink in it – you can’t go wrong.

Baking Dish

You don’t need to get a fancy dish to make an egg bake.  Use a square pyrex dish or pie dish or anything than you can put in the oven.  Just make sure that the dish is oven proof.

You will want to grease the baking dish with oil, butter or ghee so that the eggs don’t stick to the bottom of the plate.  No matter how much I grease the dish, some of my egg bake always seems to stick. But if you grease your baking dish at least the egg won’t stick to the bottom as much.

I used an 8″ pie dish, similar to the one here. But, you can use any baking dish.

How do I know When this Easy Egg Casserole is Ready?

The egg back will need 45 to 60 minutes in the oven.  You will know that it is ready when it puffs up.  At this point, take a toothpick and insert it into the center of the egg bake.  If you remove the toothpick and the toothpick is dry, then it’s ready!

Once it is ready, take it out of the oven and let it rest for at least 5 minutes.  There’s nothing worse than taking a piping hot mouthful of frittata and burning your mouth! So remember to have patience if you can.

This easy egg bake stores very well in the refrigerator as leftovers for not more than 4 days. Try to consume it as quickly as possible if your family hasn’t gobbled it all up. I would not recommend freezing cooked eggs as they generally thaw out with more moisture than when you initially placed them in the freezer.
