The primary idea here is simply cleaning out the fridge of whatever vegetables and cheese you have, pouring eggs over it, and baking. The ingredients may differ, but the technique is always the same.

Sweet Potato Brunch Casserole Ingredients

A full recipe card, including exact ingredient amounts, appears at the bottom of this post.

  • sweet potato – adds natural sweetness and texture, making the casserole hearty and filling.
  • kosher salt – enhances flavor, balancing sweetness and richness in the dish.
  • ground black pepper – provides a subtle heat and depth to the overall flavor.
  • breakfast sausage – adds savory richness and a satisfying meaty component to the sweet potato brunch casserole.
  • green onions – bring freshness and a mild onion flavor that complements the other ingredients.
  • baby spinach – adds vibrant color and a nutritious, slightly earthy taste.
  • roasted red pepper – offers a sweet, smoky flavor that brightens the casserole.
  • eggs – binds the ingredients together, creating a fluffy, custardy texture when baked.
  • whole milk – contributes creaminess and richness, helping to set the sweet potato egg bake’s consistency. We’ve tested this with 2% milk as well, and it’s fine, but not as creamy.

How To Make Sweet Potato Egg Bake

1. PREHEAT & PREP. Spray a large rimmed baking pan with cooking spray. Place sweet potatoes on one side, seasoning with salt and pepper. Put sausage links on the other side.

2. BAKE. Bake for 10 minutes, then remove the sausage and set it aside. Stir the sweet potatoes and continue baking until tender. Remove from the oven (keep the oven on).

3. ASSEMBLE. Slice sausage into 1/2-inch pieces. Spread the sausage and sweet potatoes evenly in the bottom of a casserole dish, then layer with green onions, spinach, and roasted red pepper.

4. ADD EGGS. Whisk eggs in a large measuring cup, then add milk, remaining salt, and pepper, whisking until smooth. Pour egg mixture over the casserole. Dollop goat cheese on top.

5. BAKE. Bake until eggs are set. Let cool for 5 minutes, then slice and serve.

  • Use cream or half and half for a richer flavor.
  • Make sure to whisk the eggs vigorously. It incorporates some air into the mixture which helps everything remain fluffy and light.
  • Spread the sweet potatoes and sausage evenly in the pan so they cook through at the same time.
  • Test the sweet potatoes with a fork before removing from the oven to ensure they’re fully tender.
  • Place larger pieces of goat cheese around the sweet potato egg casserole to ensure a creamy bite in every slice.

Sides For Sweet Potato And Egg Casserole

This all-in-one brunch option requires no sides. It is a meal all by itself. That means we get to serve some incredible drink options to enjoy, instead. These are some of our favorites:

Variations For Sweet Potato Casserole Breakfast

  • Choose a meat, or simply leave this meatless. If breakfast sausage links in the oven isn’t your thing, try cooking bacon in the oven, Canadian bacon or ham, turkey bacon in the oven or turkey bacon air fryer. Any meat needs to be fully cooked and chopped, sliced or crumbled before assembling this sweet potato and egg casserole.
  • Use any cheese you happen to have in the fridge for this. Cheddar, Monterey Jack and even feta are great here.
  • We use a little bit of milk to stretch our eggs further. If you don’t want to do this, you don’t have to, but you may need a few extra eggs. You could also use half and half or cream instead of milk for an extra rich and tasty casserole.
  • Want to use regular potato instead of sweet potato? Sounds great. You don’t HAVE to make this breakfast casserole with sweet potatoes. If you want to use a regular potato, we recommend a russet potato and it’s a 1:1 swap with the same cooking instructions.
  • When using different vegetables for this sweet potato breakfast recipe, you have to use your best judgement about which will need to be cooked before going into the casserole, and which can cook IN the casserole.
    • Greens like spinach and kale can go in raw, as they’ll wilt down and cook as the casserole cooks. So will thinly sliced green onions.
    • Jarred roasted red peppers are already cooked, so those can go right in to this sweet potato breakfast bake, but fresh bell pepper or something like broccoli should be cooked first so that it’s sure to come out tender in the finished casserole. You can roast those things at the same time you roast your sweet potato. Any other questions – just ask in the comments, and we can help.

How To Store Leftovers

If you have leftovers, transfer them to an airtight container and place them in the fridge uncovered for a few hours until they are fully chilled, then cover them with the lid and keep in the refrigerator up to 3 days. 

Can You Freeze Sausage and Sweet Potato Breakfast Bake?

Yes! This recipe freezes well. You can cut the casserole into pieces and wrap them individually. Store them in the freezer for up to 3 months. When you want to eat them, remove them from their wrapping, place them on a rimmed baking pan, and reheat them in a 350 degree oven until warmed through.

How To Reheat Leftovers

Honestly, we go for fast and lazy and just pop a piece into the microwave for about a minute until it’s nice and hot.

You can also reheat sweet potato breakfast casserole in a toaster oven or regular oven. Make sure the inside reaches 165 degrees F for food safety.
