Easy Sweet Potato Egg Casserole (Print Version)

Hearty breakfast casserole with sweet potatoes, eggs, cheese, and vegetables. Ready in under an hour.

# What You'll Need:

→ Vegetables

01 - 3 medium sweet potatoes, peeled and diced
02 - 1 small yellow onion, finely chopped
03 - 1 red bell pepper, diced
04 - 2 cups baby spinach, roughly chopped

→ Dairy & Eggs

05 - 8 large eggs
06 - 1 cup milk (dairy or unsweetened non-dairy)
07 - 1 cup shredded cheddar cheese
08 - 1/2 cup crumbled feta cheese (optional)

→ Pantry

09 - 2 tablespoons olive oil
10 - 1 teaspoon salt
11 - 1/2 teaspoon black pepper
12 - 1/2 teaspoon smoked paprika
13 - 1/4 teaspoon garlic powder

# How To Make It:

01 - Preheat the oven to 375°F. Lightly grease a 9x13-inch baking dish with cooking spray or a small amount of oil.
02 - Heat olive oil in a large skillet over medium heat. Add the diced sweet potatoes and chopped onion. Sauté for 7–8 minutes, stirring occasionally, until the sweet potatoes are just tender.
03 - Stir in the diced red bell pepper and cook for 3 minutes. Add the chopped spinach and cook until wilted, about 1 minute. Remove the skillet from heat.
04 - Spread the cooked vegetable mixture evenly across the bottom of the prepared baking dish.
05 - In a large bowl, whisk together the eggs, milk, salt, black pepper, smoked paprika, and garlic powder until fully combined and frothy.
06 - Pour the egg mixture evenly over the vegetables in the baking dish. Sprinkle the shredded cheddar cheese and crumbled feta cheese (if using) on top.
07 - Bake for 30–35 minutes, or until the center is just set and the top is lightly golden brown. A knife inserted near the center should come out clean.
08 - Let the casserole cool for 5 minutes before slicing into squares and serving warm.

# Expert Tips:

01 -
  • The sweet potatoes become naturally caramelized and tender while baking, creating pockets of sweetness throughout the savory egg base
  • You can prep everything the night before and just pop it in the oven for effortless weekend mornings
  • The combination of melted cheddar and salty feta creates this incredible creamy texture that makes every bite feel indulgent
02 -
  • Don't skip the step of pre-cooking the sweet potatoes, or they'll still be crunchy when the eggs are overcooked
  • The center might look slightly jiggly when you pull it out, but it will continue cooking as it rests—overbaking leads to rubbery eggs
  • You can assemble everything the night before and refrigerate, but add 5–10 minutes to the baking time since it starts cold
03 -
  • Cut your sweet potatoes into uniformly sized pieces so everything finishes cooking at the same time
  • Let the casserole cool for the full 5 minutes—otherwise you'll end up with a sloppy, unappealing mess on the plate
