Sweet Potato Sausage Breakfast Casserole

It’s taken me nearly a decade of winters in Minnesota to finally proclaim that I can hang with the polar bears around here:

1.  We count years here by the number of winters one has endured.  The more winters you’ve got under your belt, the more badges of honor.

2. Polar bears are really humans who throw their heads back and laugh in the face of extremely brutal temps.

This is the season for cozy, comforting, yet healthy breakfast casseroles to get you motivated for the day. In particular, this irresistible Sweet Potato Sausage Breakfast Casserole is one that you’ll get recipe requests for on repeat.

Commonly Asked Questions

Do you have to cook the sweet potatoes first?

The sweet potatoes will be peeled, cut, and roasted for 20 minutes prior to using. You can do this in advance and keep roasted sweet potatoes covered in the fridge until ready to assemble.

What can I use in place of kale?

We love chopped, fresh spinach leaves as much as kale leaves. You can also try cut-up broccoli florets.

What kind of sausage should I use?

Use your favorite ground breakfast sausage. Pork and turkey sausages are both delicious. Use mild or spicy, depending on your family’s preferred level of kick.

Can I make this breakfast casserole ahead of time?

The best thing about this breakfast casserole is that you can fully assemble it the night before and bake it the morning of. It makes your morning super easy!

How can I tell when my casserole is done?

The edges of your sweet potato breakfast casserole should be nicely browned, and the center will be puffy when it’s done. If you gently shake the pan, the center feel and look set – not jiggly.

  • 4 TB extra virgin olive oil
  • 1 lb sweet potatoes, peeled and cut into 1/2″ cubes
  • ½ cup onion, diced
  • 4 cloves garlic, minced
  • ½ cup diced red bell peppers
  • 1 lb ground breakfast sausage
  • 2 cups kale leaves, chopped
  • 12 large eggs
  • ½ cup milk of your choice, almond, coconut, etc.
  • kosher salt and freshly ground black pepper


  • Preheat oven to 400F with rack on lower middle position. Lightly grease a 9×13 baking dish and set aside.
  • On a large baking sheet, combine sweet potatoes with 2 TB olive oil, 1/2 tsp kosher salt, and 1/4 tsp freshly ground black pepper; toss to coat well. Bake in a single, even layer for 20 minutes until soft. Remove sweet potatoes from oven. (You can leave oven on if baking casserole right away.)
  • Meanwhile, heat remaining 2 TB olive oil on a large skillet over medium high heat. Add onions and garlic and stir 2-3 minutes or until translucent. Add peppers and stir 1 more minute. Transfer mixture to prepared 9×13 baking dish.
  • In the same skillet over medium high heat, cook and break apart sausage with spatula until cooked through. Drain and add to baking dish with veggie mixture. Add roasted sweet potatoes, and chopped kale to the mixture in baking dish. Gently toss to combine all ingredients well.
  • In a bowl, gently whisk together the eggs, 1/2 cup milk of your choice, 1 tsp kosher salt, and 1/4 tsp freshly ground black pepper until well combined. Pour evenly over the sausage/potato mixture in baking dish. Bake uncovered about 25-30 minutes or just until eggs are set in center.


  • Spinach leaves can be used in place of kale.
  • We prefer sweet potatoes, but you can also use butternut squash instead.
  • If desired, sprinkle sharp cheddar cheese on top (use lactose-free cheese if needed).
  • Dish can be prepared the night before. Cover tightly and chill. Bake uncovered in preheated oven for up to 1 hour, if baking straight from the fridge. If top is already browning at the 45-minute mark, cover loosely with foil for the remaining 15 minutes of baking.

    Made this for Easter brunch, as skeptical as everyone was at first, it ended up being a favorite. Two people asked for the recipe!

    • Rebekah

    Do you just put the fresh kale right in after the saute process? Was wondering if better to saute the kale a bit before adding.

      • Amy Dong

      As long as kale is chopped up, it’s fine to add without cooking separately. Enjoy!

    • Janell Richardson

    Has anyone tried adding cheese into the casserole, not just on top? Looks delicious already but we are cheese lovers here!

      • Amy Dong

      You can absolutely add cheese into the casserole! 🙂
