Everything Bagel Breakfast Casserole

Prepare a savory breakfast or brunch recipe; this everything bagel breakfast casserole is nutty, eggy, and high-protein dish. It will fill you up and stands out from other egg dishes!

A Savory, Easy Egg Casserole

Everyone knows that eggs are one of the healthiest things you can eat for breakfast. The problem is that there are only so many ways to make eggs and they usually taste the same. It's the spices and sauces that will make all the difference.

You already know that casseroles will feed a crowd easily. Make it once and everyone can have a slice. Did you also know that casseroles are fantastic for people that are cooking just for themselves? You can reheat leftovers over again and have breakfast all week!

This breakfast casserole tastes amazing when you heat it back up.

I added a bunch of flavorful ingredients that are also low-calorie and high in protein. This tasty casserole is as yummy as it is healthy.

Ingredients Needed

This everything bagel breakfast casserole is made with both whole eggs AND egg whites. Here's a bit more information about what I used in this healthy breakfast casserole.

• Onion: You will need to chop up half of a yellow onion. This will give an earthy flavor to the egg casserole.
• Turkey Bacon: For some crispy texture and salty flavors, chop up six slices of low-fat turkey bacon.
• Garlic: For a deeper flavor, mince and add two cloves of garlic.
• Eggs: Eggs are the base for the entire casserole. Make it healthier by using four whole eggs and three cups of egg whites.
• Cottage Cheese: Add creaminess and more protein by mixing in ½ cup of nonfat cottage cheese.
• Cheddar Cheese: It's always best to shred cheese at home than to use pre-shredded cheese. You'll only need ⅓ a cup of shredded cheddar cheese.
• Salt and Pepper: You need a pinch (½ a teaspoon) of both salt and pepper to enhance the flavor of this casserole.
• Everything But The Bagel Seasoning: This is what makes all the difference in this casserole. Use three tablespoons in this recipe!
• Everything Bagel Thins: These thins have a bunch of flavor and fewer calories than bagels or other types of bread. Use four Everything Bagel Thins in this entire recipe.

Kitchen Tools Required

When it comes to kitchen tools for this everything bagel egg casserole, keep it simple!

How To Make Everything Bagel Breakfast Casserole

If you have ever made a casserole before, then this will be super easy for you! Here is how I made this egg casserole.

First, preheat the oven to 350F and spray a 9×13 casserole dish with nonstick spray.

In a saute pan, spray with nonstick spray. Heat to medium-high heat. Once hot, add onions and turkey bacon. Cook for about 4-5 minutes or until browning.

Next, add the garlic to the onions and bacon for an additional minute, and then turn off the heat.

In a large bowl, whisk together eggs and egg whites. Whisk in the cottage cheese and cheddar cheese.

Mix in bacon and onions, and then add salt, pepper, and 2 tablespoon of Everything But The Bagel (EBTB) seasoning.

In the casserole dish, add torn bagel thins. Pour egg mixture into the casserole dish and pat down all bagel pieces to ensure they are coated. Sprinkle with the remaining tablespoon of EBTB seasoning.

Bake for 40-45 minutes or until fully cooked in middle. Let cool before serving.

There are a few different ingredients you can swap out for other ones. Here are some of the healthiest and easiest substitutions you can make.

Instead of chopping a fresh yellow onion, add about ½ a cup of frozen white onions. You can also use either fresh red or white onions instead of yellow.

You can use ricotta cheese instead of cottage cheese. Instead of shredded cheddar cheese, use your favorite type of cheese. Pepper jack cheese will make it taste spicier!

You can also use chicken sausage or vegan instead of turkey bacon.

Additional mix-in ingredients

There are a lot of different healthy ingredients that you can mix into the egg casserole.

Here are some more ideas:

• Fresh baby spinach
• Fresh parsley
• Chopped bell peppers
• Chopped tomatoes
• Sliced mushrooms

Yes, this casserole is freezer-friendly! Just bake it and then let it cool down completely. After it is completely cooled down, seal the entire casserole dish so it keeps all the air out. Then, wrap it with aluminum foil as an extra barrier and store it in the freezer for up to 6 months.

The easiest way to make this a gluten-free recipe is to buy gluten-free bagel thins. O'Doughs sells gluten-free bagels. If you cannot find gluten-free bagel thins, just use 2 full-size bagels and tear them into small pieces.
