Ingredients You’ll Need

There is nothing fancy about this recipe. You’ll need a few veggies like tomatoes and hash browns (or shredded potatoes), almond milk, eggs, basil and some spices. Many stores carry frozen hash browns that are just potatoes. You can check out this Whole30 Items at Target post, or this Whole30 Items at Walmart post to see what they carry!

Any almond milk will work, so long as it’s plain and unflavored, and doesn’t contain any added sugar. I typically use the Thrive Market brand which I order online for a discount from Thrive Market (new members get a $20 shopping credit!), but if you’re wondering what almond milks to grab, check out this list of over 25 Whole30 Compliant Almond Milk Brands & where to find them.

How to Make This Whole30 Breakfast Casserole

We love easy recipes in this household. First, you’re going to brown the ground sausage. You can also make your own sausage by using ground pork, and the seasoning blend from this homemade sausage recipe. Alternatively, you can swap the sausage for ground chicken or beef if you’d like to. You don’t have to brown it all the way, but you’ll want to transfer it to a strainer and let the grease drain really well.

To assemble the egg bake, first grease a large casserole dish, and then add 3 cups of thawed hash browns into your casserole dish to start. Crack 12 eggs in a bowl and whisk them together, add your almond milk, salt & pepper and chopped basil. Evenly pour this mixture over your hash browns and top with 2 tomatoes that you’ve thinly sliced. Place into your oven and bake at 350 degrees, be sure to check on it periodically.

Feel free to toss additional veggies into this dish. You can’t go wrong with broccoli, mushrooms, onion, or a little spinach as well in an egg bake like this. So get creative and change it up! You can also add more salt and pepper depending on your or your family’s preference.

Freezing This Whole30 Egg Bake

This Whole30 egg bake freezes and reheats really well. To freeze in individual pieces, you’ll first want to make sure to let it cool all the way first. Then you can wrap each piece in a freezer-friendly paper and then stack them in a freezer container or bag. It’s important to separate them with the paper so once they freeze, they aren’t frozen together and can you can easily pull out just one or two squares at a time.

To reheat from frozen, just pop one into the microwave for about 1 minute to 1.5 minutes, depending on how large the squares were cut!
