Sausage and Egg Whole30 Breakfast Casserole

The best part about this Sausage and Egg Whole30 Breakfast Casserole is it’s super easy to make and doesn’t require a ton of tools or ingredients.

If you’re following a Whole30 plan, you will want to make sure you are using ingredients that are sugar-free and Whole30 compliant, so I’ve linked the ones I use below.

I’ve also included a list of my favorite tools and some helpful tips for making sure your Whole 30 breakfast casserole turns out amazing!

Tips For Making The Best Sausage and Egg Whole30 Breakfast Casserole

Use fresh veggies if possible

I’ve found using fresh peppers and onions really enhances the overall flavor of the dish, and gives you a better texture for your casserole.

I also prefer to use fresh spinach, but if you use frozen spinach, make sure you squeeze any excess water out of your spinach to avoid a watery casserole.

 

Don’t overbake your casserole

I’ve found mine gets done perfectly at 28 minutes, but of course every oven is different.

A simple way to check to see if it’s done is to stick a knife in the center of the breakfast casserole and if it comes out clean, it’s done.

 

Prep your veggies and sausage ahead

Usually if I have extra time in my schedule, I’ll go ahead and chop up my veggies and refrigerate them in an airtight container until I’m ready to cook the breakfast casserole.

I also will sometimes cook my turkey sausage in advance, which helps save time.

Doing one or both of these things in advance can really help save time and effort when you’re reading to make your Whole30 Breakfast Casserole.

 

Add or switch up ingredients

This Whole30 Breakfast Casserole is a wonderful base recipe that can be variated with different ingredients and flavors to switch it up.

Feel free to add additional veggies such as mushrooms, tomatoes, broccoli, or sweet potato and/or change up the seasonings, or the meat you use.

If you’re not doing Whole30 you can also of course add yummy cheese.

I will sometimes add in some homemade taco seasoning and salsa to make it tex-mex and it’s delicious!

 

How to Store and Reheat Leftover Whole30 Breakfast Casserole

  • To Store – Store leftover Whole 30 Breakfast Casserole in an airtight container and refrigerate for up to one week.
  • To Reheat – Reheat individual servings for 30 seconds at a time in the microwave, until warm. You can also reheat the entire casserole in the oven at 350 degrees F for 5-10 minutes, or until heated.
  • To Freeze – Place individual slices in an airtight freezer-safe container or freezer safe bags and freeze for up to 3 months. When ready to eat, let thaw in the fridge overnight and reheat in the microwave.

      Yes! I’ve actually done that before and it’s still great. You can actually cut out individual serving sizes and place in freezer bags to make it easy for re-heating throughout the week.

    I love this recipe but have found that it takes way over 30 minutes to cook. It’s very funny in the middle after 30 minutes and I usually have to cook closer to 45. Any suggestions as to why this might be the case?

      Hey Maddy, it’s most likely your oven. All ovens are of course different and depending on how old or new it is, the cooking times can vary. The oven I used when making this recipe was an older oven so that could be why it took me less time. Glad you enjoyed the recipe!

    My wife loves eating breakfast casseroles. We went out one morning after eating one and right as we pulled up to a stop sign wife threw up in my car. While that was gross, it got worse because she threw up again on our carpet at home. We had to call a carpet cleaning service to get our carpets cleaned up. So far, my wife has loved your casserole. I guess I will be making your casserole from now on! My wife says thanks.
