It’s amazingly light and fluffy in texture, and yet totally easy-to-make. Foodies will love the smoky flavors in this breakfast casserole.
My sister and I always share our recipes and photos of what we made during the day or the night before, we have been doing this now for years. She made this wonderful breakfast muffin creation and sent me photos which I changed to a breakfast casserole, and is equally delicious.
She specifically made muffins so that she could freeze them and just bring them to work the next day and pop them right into the microwave.
She loves to create her own recipes and doesn’t even measure anything. Which by the way, makes it very difficult for me or anyone to duplicate her cooking exactly.
But we enjoy sharing recipes and photos of food almost every day, even if I am thousands of miles away!
So I decided to adapt her recipe into this spinach and egg breakfast casserole.
She sent me her recipe and while I am currently on a business trip in Europe with my husband and didn’t have a muffin pan, so I bought a small casserole glass baking dish instead.
This recipe will make a small casserole, and will yield about 4 to 6 servings.
Best part? Only 90 calories per serving!
Ingredients Needed for Spinach and Egg Breakfast Casserole:
-
Extra virgin olive oil: or plain olive oil is fine too.
-
Italian pancetta: gives the smoky flavor.
-
Onion: 1 small onion.
-
Eggs: 3 whole eggs, plus 5 egg whites are needed.
-
Baby spinach: fresh baby spinach is best.
-
Mozzarella: shredded mozzarella
-
Heavy cream: or half and half may be used.
-
Seasonings: salt, pepper, garlic powder, turmeric, and cayenne pepper are needed.
How to Make this Spinach and Egg Breakfast Casserole:
First, chop both the pancetta and onion. And if you can find Italian pancetta already chopped – even better! Then add some olive oil into a small skillet and saute them both for 5 to 8 minutes, until they are fully cooked.
Second, separate the egg yolks from the whites. Reserve the egg yolks for another recipe. Then add in 3 whole eggs into the bowl.
When onions and pancetta are fully cooked, turn off the heat and remove them aside to cool for a while.
Meanwhile, whisk eggs in a mixing bowl, add in the seasonings and the cream. Then slice the spinach into thinly ribbons.
Combine the onion mixture with the egg mixture. Mix in the spinach and pour the entire mixture into the casserole dish. Then bake for 22 to 25 minutes, or until the casserole is golden brown on the bottom and around the edges.
