Sweet Potato Egg Breakfast Casserole

This sweet potato breakfast casserole is SO tasty and has marshmallow-like fluffy texture of a zucchini quiche. That’s what happens when you mix shredded veggies and eggs! Layers upon layers of creamy sweet potatoes, fluffy eggs, tender spinach and gooey cheese.

It’s one of my favorite healthy egg recipes!

It is also every healthy enthusiast’s dream because we all know how hard it is to eat complex carbs, lean protein and not a lot of sugar in the morning. Three food groups, loads of nutrients, and plenty of flavor!

This sweet potato egg bake is simply amazing, serve with healthy morning glory muffins and you will feel on top of the world!

Got butternut squash? You can use entirely butternut squash and turn it into a butternut squash breakfast casserole, ha! Just peel and grate it. Easy-peasy!

Why Make Sweet Potato Egg Bake?

  • To save time: Mornings are busy, you can make this casserole ahead of time for a week of easy and healthy breakfasts or Christmas morning.
  • It’s year-round breakfast: Sweet potatoes are not only fall-winter food. There is nothing better than grabbing a cold slice of an egg bake on a hot summer day.
  • To eat a lot of nutrients in the am: Loaded with nutrients and vitamins, this healthy egg bake contains 1.5 lbs of sweet potatoes and 4-5 cups of baby spinach. When was the last time you had so many vegetables for breakfast?! Unless you tried my sweet potato hash or healthy breakfast sandwich.
  • It’s budget-friendly: Sweet potatoes, eggs and cheese are extremely affordable groceries making healthy eating possible for everyone.
  • It’s gluten-free and grain-free: Perfect for those following a special diet! Can also be made dairy-free by using a plant based milk.

Ingredients for Sweet Potato Egg Casserole

For this sweet potato egg bake, the list of ingredients might seem long. All there is to it eggs, yams, spinach, cheese and spices combined with a bit of milk for your new to-die-for breakfast go-to!

  • Sweet potatoes: This recipe calls for grated sweet potatoes. Yams and sweet potatoes are 2 different things, but there seems to be a major confusion in North American grocery stores about them. So, you can use either as they are completely interchangeable in this recipe.

To peel or not to peel “yams”? You don’t have to peel these veggies because skin contains good-for-you vitamins and nutrients and will not be noticeable once shredded. Just wash well with a cloth or scrunchy and shred o na grater. However, you can peel sweet potato if you wish.

  • Eggs: 12 large eggs, organic or free range if possible.
  • Cheese: Grate some hard sharp cheese like Cheddar, Gruyere or Swiss. I have also used marble or Tex Mex cheese with great results. You may also want to try these cheese pancakes, syrniki recipe.
  • Spinach: It adds bulk to this sweet potato breakfast and a lot of nutrients you wouldn’t consume in the am otherwise. Try air fryer breakfast casserole with spinach next!
  • Milk: Any dairy or non-dairy milk works to thicken up the egg bake. I like to use almond milk in this dish because it is tasteless and saves a few calories. I use it for a healthier swap in healthy french toast casserole, too!
  • Seasonings: Taco seasoning, garlic powder, salt and pepper.
  • Green onions or cilantro, and jalapenos: For a lot of flavor with almost zero calories.

Here is one of my favorite cooking tips: I clean and mince a few jalapenos at a time. And then freeze for any time I need a tablespoon or two. It saves time and fingers (nose and eyes) from being “on fire”.

How to Make Sweet Potato Breakfast Casserole

This incredible morning meal includes a few steps but they are all easy and straightforward. There is also a full recipe card below.

  • Prep: Preheat oven to 375 degrees F, line 9 x 13 casserole dish with parchment paper and grease with cooking spray. Grate sweet potatoes, cheese and chop other veggies.

Healthier baking tools: I buy unbleached parchment paper because it has not been bleached and harmful chemicals do not end up in our food. Instead of regular cooking spray, I use Misto bottle filled with regular oil – no propellant.

  • Whisk: In a large bowl, first add eggs, taco seasoning, garlic powder, salt and pepper. Then whisk in milk, cheese, green onions and jalapenos.
  • Mix: Stir in the sweet potatoes and spinach. Mixture will be very thick!

Spinach will wilt under heat, veggies will release liquids and eggs will set – it’s gonna work. Please follow the recipe and do not attempt to add more liquid. A few readers have done so and reported their sweet potato egg casserole did not set.

  • Pour: Transfer the sweet potato egg mixture into a baking dish lined with parchment paper and flatten it down.
  • Bake: Bake for 1 hour at 375 degrees F (may I suggest making healthy fruit salad while you wait?!). At the end, sprinkle more cheese on top and continue to bake until the cheese has melted. Let the casserole cool for 10 minutes before slicing. Serve warm.

Tips for Best Results

Just like with all my healthy recipes, I always try to use what I have on hand and this overnight breakfast casserole is one of those recipes. Whether you are watching your carb intake or would like to use garden’s bounty, here are a few tips and variations for you:

  • Adding meat: Adding turkey sausage or bacon is totally optional. If you do, saute it in a skillet before adding to the final mixture with sweet potatoes and spinach.
  • Other veggies: Kale with stalks removed and chopped will work instead of spinach. You can also add bell peppers and mushrooms, sauteing them prior in a large skillet with a bit of oil or cooking spray.
  • Up the protein content: If you would like to make casserole higher in protein, use 6 large eggs and 2 cups egg whites.
  • To save a bit of money: If you see organic baby spinach in boxes that is about to expire on sale, buy a few boxes, stick in the freezer and use in this sweet potato egg bake, lentil soup and even spinach dip.
  • Make it dairy free: Omit the cheese completely, casserole will still hold together. And use almond milk.
  • Sweet potato noodles: Got a box in the fridge and don’t know what to do with them? Use in this recipe. Also squash noodles will work.
  • For sharp cheese lovers: I often use Kerrygold Dubliner in this casserole as it adds unbelievable punch of flavor to bland veggies. I know it’s not everyone’s favorite like blue cheese isn’t but I love it so had to share! By the way, it doesn’t freeze well – it crumbles when grating or slicing.kerrygold dubliner cheese

Common FAQs

Can I use regular potatoes or hashbrowns?

You can use regular potatoes. Peel, shred and give them a good squeeze as they contain more moisture than sweet potatoes. You can also make this hashbrown breakfast casserole all together.

You can use store-bought hash browns as well. I would reduce salt to 1/2 tsp and keep in mind casserole will be not as healthy.

How many sweet potatoes is in 1.5 lbs?

1.5 lbs of sweet potatoes equals 3 LARGE sweet potatoes.

Can I make it in slow cooker?

I haven’t tested this recipe in the slow cooker but you can loosely follow this slow cooker recipe directions. Please let me know how it comes out.

        This was a little far from our usual flavor profiles – so my husband & daughter liked (but didn’t love) it. They are crazy – this is terrific! I was happy to finish the leftovers for lunch over the next couple of days!

      2. 5 stars
        We’ve made this several times and greatly enjoy it. It’s a great make-ahead breakfast for the work week. While it’s great as is, we’ve also added chorizo to it, whcih really takes it to another level!
