Ingredients for the Best Breakfast Casserole

Easy Make Ahead Hash Brown Breakfast Casserole

These easy breakfast casseroles pack a ton of flavor while still having a pretty simple ingredients list. It just goes to show you that you do not need a ton of complicated ingredients to make a delicious healthy breakfast.

To make these breakfast casseroles, here’s what you need:

  • Bacon (look for a sugar-free variety if you need to keep this casserole Whole30 compliant)

  • Red bell pepper

  • Baby spinach

  • Green onion

  • Eggs

  • Coconut milk

  • Buffalo sauce

  • Salt, pepper, and garlic powder

I like to drizzle a little extra buffalo sauce over the casserole once it’s finished for even more flavor, but of course, that is totally optional.

How to Make a Hash Brown Breakfast Casserole?

Making these hash brown breakfast casseroles really could not be any easier. All you need is an hour on a Sunday afternoon to prep your breakfast for the entire work week!

Step 1: Cook your bacon and prep your ingredients. To make the bacon, slice it into small strips and cook until crisp. When the bacon is done cooking, remove it from the pan and let it drain on paper towels.

While the bacon is cooking is the perfect time to prep the rest of the veggies. Dice your bell pepper, chop the spinach, and prep the green onion. This recipe calls for frozen shredded hash browns which keeps things extra easy.

Step 2: Make the egg mixture. A lot of the flavor in these casseroles comes from the egg mixture. The eggs are whisked with buffalo sauce, salt, black pepper, and garlic powder. They also get a heavy pour of full-fat coconut milk to make sure the eggs are light and fluffy.

Step 3: Once the veggies, bacon, and eggs are prepped, all you have to do is assemble each of the casseroles in their individual baking dishes. I love using the Ello DuraGlass 10pc Meal Prep Set to keep things simple and easy.

Start with a tiny bit of oil in each container to ensure that nothing sticks, then add the potatoes, red bell pepper, baby spinach, and bacon. Pour the egg mixture evenly into each container, top with sliced green onions, and bake at 400 degrees until cooked through and set in the middle. So easy!

Why I Love Ello Meal Prep Containers for these Easy Casseroles

I love using Ello DuraGlass Meal Prep 10pc Meal Prep Set to make these casseroles because they can go from freezer to oven to table. You can easily bake and store the casseroles in the exact same dish, which is literally a meal prep dream come true.

 I also prefer to store food in glass containers over plastic because they are free from any harmful chemicals and also better for the environment. These containers are BPA free, which is a must for me, and dishwasher safe.

Meal prep can feel a little daunting for people but it does not have to be. I love that Ello DuraGlass containers help to take some of that overwhelm away. Not only does baking and storing these casseroles in the same container save you time on washing dishes, it makes the entire process of meal prep easier and more efficient.

Each Ello DuraGlass meal prep container also has an air-tight lid that easily snaps on to keep my food fresher longer. Plus each lid is crystal clear which so you can see what is in each container, so there is no more second-guessing what’s in your fridge. The bright silicone sleeves also makes it easy for you to see them in your refrigerator which is super helpful.

Can You Make These Casseroles Overnight?

Yes! These make ahead casseroles are the perfect thing to make the night before and then bake in the morning. Just do all of the prep the night before, including pouring over the egg mixture. The snap on the container lids and store them in the refrigerator.

The next morning, when you are ready to cook, remove the lids from the container and place in the oven to bake. I love letting the casseroles bake while I’m getting ready for work in the morning. By the time I’m all set for the day, breakfast is done and ready to eat!

    Hi!

    This looks amazing. I’m not generally a fan of buffalo sauce. Any recommendations for other flavor pairings?

    1. Ashlea Carver says:

      Hi, Tamika! You could use hot sauce or just leave it out entirely. Hope that helps!

  2. I made these for the kids and they are perfect! Delicious, fluffy, and full of flavor. I made it in one 8×8 casserole dish and then cut into squares. I then froze at hem in batches for quick and easy grab for breakfast or snack. My husband said he wants a batch ftake a picture later this month if 2nd go around.






    1. Ashlea Carver says:

      Thanks for sharing, Laurie! I’m so glad you enjoyed the recipe!

  3. Jillian Petrosky says:

    Made this on Sunday and decided to do the full casserole dish versus mini dishes and it turned out wonderfully. We drizzled with the Primal Buffalo and I cut up some avocado to go with. Very yummy!!!






    1. Ashlea Carver says:

      So glad you loved the recipe, Jillian! thanks for sharing!

  4. If you are prepping 5 containers for the week, do you bake them all at one time and refrigerate or freeze till ready to use later in the week?

    1. Ashlea Carver says:

      Hi, Carla! I bake them all at once!

  5. Hey 🙂 what’s the best way to reheat it you’re cooking ahead? Can they be reheated in the microwave?

  6. This looks delicious! Can you make this in one casserole dish?

    1. Ashlea Carver says:

      Thank you! Yes! you definitely can!

  7. This looks and sounds delicious, definitely on my list to prepare. I also the idea of making multiple casseroles for meal-prep and freezing. What size casserole dish are you using, is it 8×8, and this recipe makes 5 separate casseroles with this size container? Thanks!

    1. Ashlea Carver says:

      Hi, Linda! Yes-this recipe will make five different casseroles with the containers I linked to in the post. Of course, you could use a casserole dish instead and just bake one large casserole. Hope that helps!

  8. Tracee Redmond says:

    If cooking in one casserole dish is the cooking time the same or more?

    1. Ashlea Carver says:

      Hi, Tracee! It would depend upon the size of the casserole dish you use. I would check the casserole around 20-25 minutes and just bake until it is set. Hope that helps!
