A few notes about the key ingredients
- Turkey sausage – I used pre-cooked, but uncooked turkey sausage also works. You can also substitute this for bacon or pork sausage.
- Veggies – I used sweetpotatoes, mushrooms, onion and red bell pepper. You could also swap white potatoes in for the sweetpotatoes. Adding spinach, or greens, would also be delicious.
- turkey sausage – I used pre-cooked, but uncooked turkey sausage also works. You can also substitute this for bacon or pork sausage.
- eggs – I used six eggs total, but some readers had success with 8 eggs also.
- shredded cheese – Goat cheese or feta cheese would provide a deeper flavor punch!
- evaporated milk
- spices – garlic powder, Italian seasoning, salt and pepper

And then the oven does most of the work while you can get your chores done, like laundry, cleaning, other meal prep (my meal prep ebook breaks down reusing leftovers and prepping multiple meals at once!) or even sneak a quick workout in.
You can easily do the preparation the morning of, and it will take about 10 minutes of prep!
To prep, cook your turkey sausage if it’s not pre-cooked. Cook your veggies as well in a hot skillet over medium high heat with a little olive oil, butter or coconut oil.
Prep Tip
Try to dice your sweetpotatoes in a consistent shape and size, so they cook quicker and more evenly.
Whisk your ingredients in a bowl, adding in the cooked veggies and turkey sausage last.
Then, let them cool and pour in a casserole dish for baking.
Bake for 45-55 minutes or until cooked through.

Tips for Storage and Freezing
- This turkey sausage breakfast casserole recipe will stay fresh for 3-4 days in the fridge. Or you can freeze it in freezer safe tupperware for up to 3 months!
- To make this advance, get all of the prep work done until baking, and cover with aluminum foil. Then, place in the fridge overnight. In the morning, bake as described and then cut into individual slices after letting cool.
- You can also freeze for later. To freeze, cover the unbaked casserole tightly. It will stay for 2-3 months in the freezer. When ready to bake, allow to thaw overnight in the freezer and then follow baking instructions. I’ll just prep two at once and freeze one for the following weeks

I love your recipes but I have to omit cheese because it does not go well with me. I always had difficulties eating cheese. What can I add instead of cheese? Thank you
Hi Suzanne!
Have you ever tried a plant-based or cashew cheese? For shredded cheese, sometimes nutritional yeast can work to give that “cheesy” flavor!
Easy to make and great taste
This breakfast casserole looks great, Sarah.
We regularly make the Baked Sweet Potato Oatmeal casserole with blueberries from your recipe – the BEST!
Thank you!
