You’ve probably heard of southwestern omelet casserole, western omelette, baked Denver omelet casserole, or something similar, but we prefer to keep this omelet recipe very simple, wholesome, and downright delicious. 

Fun fact, I was somewhat of a picky eater when I was younger. Bell peppers, green peppers, or even green onions were firmly on the “Inedible” list in my mind. (Thankfully I’ve since learned to enjoy such things!)

Breakfast casseroles are great options when it comes to hosting overnight guests or serving a large group as well.

How to make Easy Oven Baked Omelet Breakfast Casserole

Preheat the oven to 350 degrees, and grease the baking dish you plan to use with cooking spray or butter.

Chop the bread slices into cubes with a kitchen scissors, then layer in the bottom of a greased 9 x 13 baking pan or casserole dish.

On top of the bread, layer the fried, chopped bacon and shredded cheddar cheese.

Dump the eggs, milk, salt, pepper, basil, parsley, and onion powder into a glass Pyrex measuring pitcher or large bowl and use an immersion blender or handheld electric mixer to blend everything together into a smooth egg mixture.

Pour the egg mixture slowly and evenly on top of all the ingredients already in the pan.

Bake the casserole uncovered at 350 degrees for 25 to 30 minutes or until it’s starting to turn golden brown on top, puffed up slightly and the egg mixture is set. 

Serve immediately. Enjoy!

Notes 

Store leftovers in an airtight container in the refrigerator for up to 5 days. Leftover casserole makes for a quick and wonderful breakfast the next day! 

If you’re needing to cook the bacon first, see description below, explaining how we did it.

You can also substitute the bacon with cooked ground sausage or diced ham, or whatever breakfast meat you wish to use!

As always, we use fresh herbs whenever we can in place of the dried ones!

Along with the onion powder, we sometimes add a dash of garlic powder as well.

Don’t panic; this casserole will puff up in the oven then fall back down slightly as it cools.

What’s the best way to cook raw bacon?

Our all time favorite easy way to fry bacon is in the oven:

1. Line a baking sheet pan with aluminum foil.
2. Arrange the bacon in a single layer on the lined pan.
3. Stick in the cold oven on the top rack and and set the oven to 375 degrees.
4. Bake for 15 – 25 minutes, depending on how thick your bacon is, and how crispy you want it.
5. Remove from the oven and transfer bacon to a strip of paper towels to soak up the excess grease. 

You can also use a microwave bacon tray for a more speedy process. 

Frying bacon in a pan on the stovetop is another way, though it’s also more of a mess, in our opinion.

However you choose to fry your bacon, don’t throw out the bacon grease! Take a look at these ideas on how to use bacon grease.
