How to Make the Best Protein-Packed Sweet Potato Egg Casserole (Step by Step)
Preheat your oven to 400°F and grease a 9×13-inch baking dish.
This high heat gives you golden, crispy edges on the sweet potato.Toss the grated sweet potato with olive oil, salt, and pepper; spread in the dish.
Pat it down slightly so it roasts evenly and crisps at the edges.Roast the sweet potato base for 15 minutes until it starts to brown.
This step builds that crispy texture everyone loves.Meanwhile, whisk eggs, milk, smoked paprika, and half the cheese in a bowl. Stir in spinach and cooked meat if using.
Whisk just until combined for a light, fluffy bake.Remove the dish from the oven and pour the egg mixture over the roasted sweet potato. Sprinkle remaining cheese on top.
Pour gently so the base stays layered and pretty.Bake at 375°F for 20–25 minutes until the center is set and the top is golden. Let it rest 5 minutes before slicing.
Resting finishes the custard and makes clean slices.
You’ll know it’s ready when the center is set and the top is golden and slightly puffed. The smell alone will bring everyone to the kitchen.

Serve warm in wedges for a cozy brunch plate. Pair with a crisp green salad and a citrusy vinaigrette or with avocado slices and hot sauce for an adult version.

Frequently Asked Questions
Can I make Protein-Packed Sweet Potato Egg Casserole ahead of time?
Yes. Assemble, cover, and refrigerate overnight. Bake the next morning as directed, adding a few extra minutes if going straight from fridge.
What can I substitute for sweet potato?
You can swap sweet potato with butternut squash or shredded regular potato; note the flavor will be less sweet and the texture a bit denser.
Why did my Protein-Packed Sweet Potato Egg Casserole turn out soggy?
Most often you didn’t roast the sweet potato first or you used too much liquid. Roast the base until it browns and drain excess moisture from grated potato before assembling.
