Egg Casserole: Ingredients

The first step in making this egg casserole recipe is to prepare the ingredients. So let’s discuss the components of this dish, as well as possible substitutions.

• Bacon.There are so many varieties of bacon out there that would be perfect to use in this egg bake recipe. I recommend choosing a thick variety with great flavor (hickory smoked, etc.) Turkey bacon can also be used, but because of the lower fat content, you will likely need to add 1 Tablespoon olive oil to the fry pan when you add the veggies to cook them well. You can also use crumbled breakfast sausage in place of bacon. If you wish to leave out the bacon and make this vegetarian, use 2 Tablespoons olive oil to sauté the vegetables.
• Onion.I usually make this egg casserole with a sweet, white onion. Any variety works well: red onion, yellow onion, green onions, etc.
• Bell Peppers. I like to use a mixture of red and green bell peppers for color (it’s especially festive for a Christmas morning breakfast). You can use any bell pepper variety you choose (red, orange, yellow, green, etc.) If you don’t like peppers, substitute 2 cups of your favorite vegetables (broccoli, carrots, celery, zucchini, etc).
• Eggs.there is no substituions for eggs in this healthy breakfast casserole recipe.
• Cheddar Cheese.I recommend an extra sharp cheddar cheese for the best flavor. Other cheeses that taste great in this egg bake recipe are: Colby jack, Swiss cheese, pepper jack (for a spicy flavor) and mozzarella.

How to Make Egg Casserole

This breakfast casserole with bacon is fairly easy to make! As always, you can follow along with the photos for step-by-step instructions and a few helpful notes, or you can watch the video (or both).

Cook Bacon & Veggies

The first step in making this recipe to sauté the bacon, onion and garlic over medium heat until the bacon just begins to brown. Be sure to stir every few minutes.

Note:For a vegetarian version (without bacon), simply add 2 TBS olive oil to the pan and sauté the onions and garlic together until the onions are soft, then add the rest of the veggies.

Once the bacon just begins to brown, add the diced peppers and stir until they are evenly dispersed in the bacon/onion mixture. Cover and cook for 5-7 minutes, stirring every minute or two. Cook until the bacon is browned and the peppers are soft.

Cool

Remove the pan from the heat and let the veggie/bacon mixture cool while you make the rest of the egg casserole recipe.

Make the Egg Mixture

While the bacon/veggie mixture is cooling, whisk the eggs together until they are uniform in color and smooth. Then add the seasoning to the beaten eggs and whisk to combine.

Assemble the Egg Casserole

Add the cooled bacon/vegetable mixture to the egg/spice mixture and stir to combine. Next, add the cheese and stir until it is evenly distributed.

Bake

Pour the egg casserole mixture into a 9×13″ baking dish and bake in the preheated oven for 25-30 minutes, or until the top is set and slightly browned.

You can also check the doneness of an egg bake recipe by testing the internal temperature. When an instant read thermometer reads 160 degrees F, the breakfast casserole is done.

Cool for 5 minutes, cut and serve warm. I like to serve this healthy breakfast casserole with a side of roasted potatoes, oven baked bacon, roasted sweet potatoes, or a delicious salad.Or try any of our breakfast recipes.
