Dairy Free Slow Cooker Breakfast Casserole

I started out with my 9×13 casserole Crockpot, but you can use a 6 quart oval Crockpot if you don’t have this type. Spray the bottom and sides of your slow cooker with nonstick cooking spray. This will make clean-up easier! Peel and shred one medium sweet potato with a cheese grater and sprinkle them into the bottom of the slow cooker. These sweet potato hash-browns will serve as your first layer for this amazing Breakfast Casserole. Now that the hash-browns have been added, sprinkle 1 1/2 cups of fresh baby spinach on top. If you’re looking for ways to incorporate more greens into your breakfast meals, this is a great way to do it! You’ll notice here that I haven’t added any dairy – this is a completely dairy free breakfast casserole but it can be added if you desire it.

Turkey Sausage is a great source of healthy protein without unhealthy additives

Now that your vegetable base has been added, it’s time to cook the onion and turkey sausage. Add 1 teaspoon of extra virgin olive oil to a large skillet and heat until hot. Peel and dice a yellow onion and saute it in the oil until translucent. Add in the 1lb roll of ground turkey sausage and use a spatula or meat masher to break it into small crumbles as it cooks. Once the turkey is cooked through, drain off any grease and add the cooked turkey and onion to the ingredients in the slow cooker.

Farm-fresh eggs makes this Slow Cooker Breakfast Casserole delicious!

The inspiration for this meal came when my neighbor gave us nearly 2 dozen farm-fresh eggs one morning. When you have farm-fresh eggs, you just have to make something fabulous with them! I used 14 of those eggs in this casserole and I think they just made it fabulous. While you don’t have to use fresh eggs, they certainly are wonderful if you have them on hand! Whisk 14 eggs in a large bowl with 1/2 teaspoon of salt and 1/2 teaspoon of pepper. Pour the whisked eggs over the ingredients in the slow cooker.

Place the lid on the slow cooker and cook on high 3 hours or low 6 hours. Once cooked, remove the lid and turn the heat off. Cut the casserole into 8 equally sized squares and garnish with sliced cherry tomatoes or diced avocado. It can also be served with salsa or some hot sauce for an extra flavor punch. I’m a Frank’s Red Hot girl and an “I want all the condiments” kinda person, so I loaded my slice down – it was incredibly tasty too!

Storing and re-heating this Slow Cooker Breakfast Casserole is easy!

This Paleo Breakfast Casserole is so good re-heated that it makes the perfect breakfast meal-prep recipe. I like to portion out the leftovers into small, airtight containers that are microwave safe. For a fast breakfast on the go, simply pop your container in the microwave for 1 minute to heat. It can be stored in the fridge for up to 4 days. If you’re doing a Whole30, you’ll be happy to know this Breakfast Casserole is Whole30 compliant! Just read the ingredients on your turkey sausage to make sure it doesn’t have any sneaky sugar.
