Your new favorite breakfast casserole

If you’re like me, sometimes breakfast consists of a hurry-up-and-run-out-the-door granola bar, and sometimes it consists of a 3-course feast complete with all of the fixings.

For those mornings when you’re going with the latter, this egg and sweet potato casserole is perfect!

Baked to perfection for ~50 minutes, this savory and filling meal is made with everything delicious, like veggies, sausage, eggs, and even mozzarella cheese. It feeds a crowd, so it’s perfect for a nice brunch with friends and family.

Ingredients in this sweet potato breakfast bake

For this breakfast bake we’re including everything yummy: onion, green pepper, potatoes, eggs, sausage… If it’s a breakfast go-to, it’s in this dish! When all of these ingredients are combined, you’re left with a to-die-for sweet potato casserole with eggs.

  • Avocado oil: The first ingredient in our egg bake is avocado oil. We will use 2 tbsp to sauté the veggies!
  • Yellow onion: First up for our veggies, we’ll be using 1/2 of a large yellow onion, diced into small pieces.
  • Green pepper: Add a diced green pepper for extra flavor.
  • Sweet potatoes: For the bulk of the veggies and to add some oomph, we’re including 5 cups of chopped sweet potato.
  • Garlic: 3 cloves of garlic will be added to give this casserole a great flavor!
  • Turkey sausage: Then, you’ll need 1 lb of turkey sausage.
  • Eggs: The eggs make this a true breakfast casserole. You will need 10.
  • Milk: To thicken up the egg bake, include 1/2 cup of milk. You can use a nut milk here if desired.
  • Thyme: For flavor, include 1 tsp of dried thyme.
  • Salt: Similarly, add 1 tsp of salt.
  • Pepper: Last up for the seasonings is 1/2 tsp of pepper.
  • Cheese: Finally, 1/2 cup of shredded mozzarella will be mixed with the whisked eggs for flavor and deliciousness!

Items needed to create this dish

You will need a few different tools to make egg and sweet potato casserole. Start with your chopping items, then grab a baking dish, a sauce pot, and some utensils. Don’t forget your mixing bowl and measuring cups!

  • Cutting board
  • Chopping knife
  • 9×13 casserole dish
  • Large sauce pot
  • Stirring utensil
  • Small mixing bowl
  • Whisk

You will need the following sized measuring cups: 1/2 tsp, 1 tsp, 1 tbsp, 1/2 cup, and 1 cup.

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 sautéing 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 sauté. 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 sauté 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.

    I am planning to make this for the morning after Thanksgiving, but I won’t be at my house. Can I make the casserole ahead of time, bake, then freeze and reheat?

    LOVE this and so does everyone I made it for. I am adding this to my Christmas brunch menu. I used a regular-size circular pie dish so I only used 6 eggs. Part of the top didn’t fully bake of the egg but I think its because I didn’t mix the egg and milk enough before adding the cheese. Thanks for the recipe!

    If you double the recipe, do you recommend making it in two separate 9×13 pans, or all in one?

    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

    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 😋

    Don’t sleep on any of Erin’s egg casseroles. Made this for my boyfriend and I as meal prep this week and it will 100% become a regular on our menu. The sweet potatoes make it hearty without feeling overly heavy. Easy to throw together too! 10/10 recommend!
