Healthy Breakfast Casserole #breakfastcasserole #easybreakfast

Marie starts school next month, so I am mentally preparing for the morning rush of getting out the door to school on time.  I want to make sure to serve a nutritious and filling meal to start the day, but I also don’t have a ton of time in the morning, so I plan on meal prepping some breakfast meals like my Berry Oatmeal Breakfast Bake and Potato Breakfast Burritos.

My mom has been making a delicious breakfast casserole for the past few years that is also great for meal prep and has entered our regular breakfast rotation. I’ve made a few tweaks (like using extra virgin olive oil to coat the pan and adding in an entire package of spinach), and it’s tasty, satisfying, and a great breakfast option for mornings with an early start time.

Ingredients in Healthy Breakfast Casserole

Extra Virgin Olive Oil Olive oil is used to help the casserole come out of the pan a little easier. Extra virgin olive oil also contains heart healthy monounsaturated fatty acids as well as a good amount of antioxidants.

Spinach Spinach is a good source of fiber and a variety of vitamins and minerals that our body needs for optimal function.

Hash Browns I use frozen, shredded hash browns for this recipe, which are a form of potato. Potatoes are particularly rich in potassium.

Turkey or Chicken Breakfast Sausage Lately, I’ve been enjoying Applegate Farms Chicken Sage Breakfast Sausage. It’s delicious and contains a very low amount of added sugar.

Eggs Eggs are rich in many nutrients associated with eye health such as choline, lutein and zeaxanthin. They also contain protein and many other vitamins and minerals.

Cottage Cheese Cottage cheese helps the eggs puff up and also adds extra protein and calcium to this dish.

Cheddar Cheese Cheddar cheese is a delicious addition to this healthy breakfast casserole, but you can use any cheese you prefer!

How to Make Healthy Breakfast Casserole

The only thing you need to cook ahead of time is the breakfast sausage and the spinach. Once those items are prepped, coat a 9×13 pan with extra virgin olive oil and sprinkle in the frozen hash browns. In a large mixing bowl, combine the eggs, cottage cheese, cheese sausage, and spinach. Whisk it all together then pour the egg mixture over the top of the frozen hash browns.

At this point in the recipe, you can either cover the 9×13 pan with a lid or foil and place it in the fridge until you are ready to cook your Healthy Breakfast Casserole. The other option is to bake it right away. I frequently do the prep ahead option then pop it in the oven the following morning.

How to Serve Healthy Breakfast Casserole

We love serving this casserole with a side of fruit for an extra serving of produce to start the day. The great thing about this healthy breakfast casserole is that it contains all the breakfast components in it!

Healthy Breakfast Casserole. Something we make almost weekly in our house! Prep it the night before you want to eat it, then pop it in the oven and serve the next morning. Eggs, cheese, spinach, chicken sausage, hash browns…delicious!



3 tablespoons extra virgin olive oil, divided

5 oz container of spinach

3 cups frozen shredded hash browns

1 lb cooked turkey, chicken, or plant-based breakfast sausage

¼ teaspoon salt

¼ teaspoon black pepper

7 large eggs

16 oz cottage cheese

1 ½ cups shredded cheddar cheese


  1. You can prep all of this ahead and put in a 9×13 baking dish, covered in the fridge until ready to put in the oven.
  2. Preheat the oven to 350 degrees Fahrenheit. Coat the bottom of a 9×13 baking dish with 2 tablespoons of extra virgin olive oil.
  3. Heat the remaining 1 tablespoon of olive oil in a large pan over medium-low heat. Add the spinach and season with salt and pepper. Cook until completely wilted down.
  4. Spread the frozen shredded hash browns in the bottom of the prepared baking dish.
  5. Sprinkle the cooked breakfast sausage and cooked spinach over the frozen hash browns in an even layer.
  6. In a large bowl, whisk the eggs and the cottage cheese together. Then mix in the cheddar cheese. Pour this mixture over the hash browns, sausage and spinach.
  7. At this point you can either cover this uncooked casserole and place in the fridge, or you can place it in the preheated oven and bake for 45 minutes, or until the mixture is firm in the center and the edges are golden brown.
