How to make sweet potato egg breakfast casserole
This tasty morning dish includes a good amount of steps, but they’re all simple and straightforward. Start by chopping and sautรฉing the vegetables, and then put them in a casserole dish. Repeat, this time with the turkey, add the egg and cheese mix, and bake!
Below is the step-by-step breakdown:
First, chop the vegetables as directed and grease a 9×13 casserole dish.
In a dutch oven or large sauce pot, add avocado oil.
Once hot, add onion, green pepper, and sweet potato and cook for 8-9 minutes (or until soft).
Throw in garlic for the last minute or two and sautรฉ. Remove the veggies and lay them in the bottom of a 9×13 pan.
Next, add the turkey sausage to the same dutch oven and sautรฉ until fully cooked. Add the veggies and stir to mix.
In a separate bowl, whisk the eggs, milk, thyme, salt, pepper, and cheese.
Pour the egg mixture over the veggie and sausage mixture and stir evenly until dispersed.
Bake for 40-45 minutes, or until the center is firm. If it starts to brown halfway through, cover with foil.
Finally, let cool for 15 minutes and serve!
Substitution Tip
Sweet potato egg breakfast casserole is pretty versatile in that you can use a number of ingredients to achieve an equally delicious result. Here are some simple substitutes that you may want to try!
- Yellow onion: If you want a more potent onion taste, try using a red onion instead.
- Green pepper: Your green pepper can be swapped with a red, orange, or yellow pepper for a similar result.
- Turkey sausage: If you’d like, you can swap the turkey sausage with the sausage of your choice, whether chicken, pork, or something else. A plant-based alternative will work too!
- Milk: As mentioned above, any type of milk will work. You can use regular dairy, or you can go with almond, cashew, oat, or whatever you like!
- Mozzarella cheese: Finally, I love to use mozz cheese in this dish, but many types will be tasty! You could use cheddar, pepper jack, or even Swiss.

Would it be possible to assemble all of the casserole ingredients, but then refrigerate it overnight, and bake it in the morning?

Just made this for our evening meal and served it with flaky layer biscuits, hot tea, coffee and O.J. It was a huge hit with everyone! My pooch even got to sample a bite as it hit the floor. Seriously, I have a difficult crowd to please and a healthier option is always at the top of my list. This has made it to the rotation of monthly meals. Thank you so much for sharing. If you have not made it yet, make it a priority for yourself. Seriously, this was like comfort food that your dietician would approve. 10/10

Makenzie says
Oh boy this was soooo yummy! Perfect for fall. I never comment on recipes but this one I had to.
I kept all the ingredients the same. After 45 minutes baking it didn’t seem cooked all the way in the middle so I put foil on top and baked for another 10 minutes. I probably overcooked it a little but it was still delicious ๐
