This quick and easy egg casserole recipe ticks off a lot of boxes: It can be made ahead for a no-fuss brunch recipe, it’s low-carb and keto-friendly, it’s gluten free, and this overnight egg casserole is delicious.
When springtime rolls around, those of us who raise chickens often find ourselves with a glut of fresh eggs. It’s a good problem to have, certainly, plentiful food produced right on site. But when there are lots of eggs, we need recipes that use up lots of eggs. This recipe does the trick! (You can use duck eggs, too. Because duck eggs are larger than those of chickens, use eight rather than a whole dozen for this recipe.
How to make baked egg casserole
Eggs – Use a dozen fresh eggs, store bought, use what you have readily available.
Milk – Use half a cup of whatever type you typically keep on hand.
Ham – This is one of the key components of this dish to add some protein to your meal.
Bacon – Use 6 slices bacon, browned, drained and crumbled.
Spinach – Fresh spinach chopped into tiny pieces.
Onion – Grab a half cup of diced onions. You can use any kind of bulb onion you have on hand — white, yellow, or red.
Cheese – Two cups of your favorite type of cheese. Shredded mozzarella goes best with this dish.
First, preheat the oven to 350 degrees, then mix the eggs, milk, salt, and pepper in a bowl. In a baking dish, add the ham, bacon, onion, and spinach. Create an even layer in the dish, and pour the eggs over the top of the mixture.
Add a layer of cheese, and pop it in the oven for about 45 minutes. You can also cover and store the pre-made casserole in the fridge until you’re ready to cook.
Variations on this overnight egg casserole are almost endless. Use crumbled and browned breakfast sausage instead of bacon. Swap cheddar cheese for the mozzarella. Stir in some chopped fresh or sun-dried tomatoes.
This easy egg casserole is nice enough for company, too! (Serve it with some homemade hash browns if you’re not sticking to a low carb eating plan.)
What’s the difference between a quiche and an egg casserole?
A quiche is normally an egg custard that gets baked into a pie shell, while the casserole is baked in a dish instead of a pan.
How do you know when egg casserole is fully cooked?
