Whole30 breakfast recipes are a challenge for me.

I need them to be…

  • quick
  • easy
  • damn delicious

And if they’re not? I’d honestly rather skip breakfast, which is a no-no on a Whole30!

So I make my Whole30 breakfast a priority.

I have a super non-Whole30 breakfast recipe I absolutely love (Though the post and photos are insanely embarrassing, I’ll let you look if you want), loaded with shredded hash browns and a creamy béchamel sauce and breakfast sausage and lots and lots of cheese. I love it so much and never tire of eating it but decided it was time to make it a bit healthier!

Why this hash brown and sausage Whole30 breakfast recipe is so good:

  • I used my hash brown and sausage casserole as the inspiration but focused on creamy eggs and a dairy-free sauce, making it healthier and more filling at the same time. Whole30 breakfast perfection.
  • It’s creamy and rich, thanks to the coconut milk and eggs.
  • The pre-shredded hash browns make it an easy Whole30 breakfast to throw together on a Sunday for meal prep to eat all week.

When I made it the first time, we ate it for dinner, and my husband finished… wait for it… An entire half of the dish. Whoa. While not a serving size I’d necessarily recommend, it just truly goes to show how delish this Whole30 breakfast is! 

Variations

  • Use coconut milk instead of cashew cream if you’re allergic to nuts: use 1 13.5-ounce can of coconut milk or cream.
  • Shred your own hash browns: peel a couple of Russet potatoes and shred with a box grater or food processor. Wrap in a paper towel and squeeze to reduce any excess moisture.
  • Use cassava flour in place of the arrowroot powder if you prefer.

Tips

  • Make your Whole30 breakfast sausage with my super easy recipe.
  • Use frozen hash browns – they’re easier to find Whole30 compliant – and let them thaw a little ahead of making this Whole30 breakfast.
  • A knife inserted into the center of the casserole will not come out clean when it’s done, but the surface will be firm.
  • You can use tapioca flour if you don’t have arrowroot or cassava flour on hand.

How to make this Whole30 breakfast recipe:

Brown sausage in a large skillet, crumbling with a spatula or wooden spoon.

Brown sausage

Meanwhile, make cashew cream. Put 3/4 cup raw cashews in a 2-cup measuring cup then pour warm or hot water over to make 2 cups. Let side while sausage browns then blend in a high-speed blender until very, very smooth. Alternately, skip this whole thing and use 1 13.5-ounce can coconut milk.

Sprinkle arrowroot over browned sausage then stir in 1 1/2 cups cashew cream. Bring to a boil and cook about 3-5 minutes or until mixture thickens. Season with lots of freshly ground black pepper.

Sprinkle arrowroot and cashew cream over

Whisk together eggs and remaining cashew cream, salt, spices, and 1/3 of the sliced green onions.

Whisk together eggs, cream, green onions, and seasonings

Spread hash browns evenly in a 3-quart baking dish and season with a bit of salt. Top with 1/3 of the green onions, then the sausage mixture, then the egg mixture. Bake at 350º for 45-50 minutes or until the surface is firm. Sprinkle with remaining green onions, let cool slightly, then cut into squares, and serve.

Layer casserole and bake

  5. In a baking dish, spread hashbrowns evenly, and sprinkle with a pinch of salt. Top with 1/3 of green onions, then sausage mixture, then egg mixture. Bake 45-50 minutes then sprinkle with remaining green onions. A knife inserted in the center won't come out clean because of the creamy sauce, but the surface should be firm.
