Ingredients You’ll Need
Sweet Potato Base
- 2 medium sweet potatoes, peeled and diced (about 3 cups)
- 1 tablespoon olive oil
- ½ teaspoon salt
- ¼ teaspoon black pepper
Egg Mixture
- 8 large eggs
- ½ cup whole milk (or unsweetened almond milk)
- ½ teaspoon garlic powder
- ½ teaspoon paprika
- ¼ teaspoon salt
Add-Ins and Flavor
- 1 cup shredded sharp cheddar cheese
- ½ cup diced yellow onion
- 1 cup fresh spinach, roughly chopped
For the Baking Dish
- Nonstick spray or softened butter
Step-by-Step Instructions
Step 1: Prepare the Sweet Potatoes
You start by preheating your oven to 400°F. Dice the sweet potatoes into small, even cubes, about ½ inch each. Toss them with olive oil, salt, and pepper, then spread them on a parchment-lined baking sheet. Roast for 18–20 minutes until tender and lightly golden. This step builds flavor and ensures the potatoes cook evenly in the casserole.
Chef’s Tip: Smaller, evenly cut cubes cook faster and prevent crunchy bites in the finished dish.
Step 2: Prepare the Baking Dish
Lower the oven temperature to 375°F. Lightly grease a 9×13-inch ceramic baking dish with butter or nonstick spray. This step prevents sticking and makes serving easier, especially for beginners who want clean slices.
Chef’s Tip: Grease the corners well, this is where casseroles love to stick.
Step 3: Layer the Vegetables
Transfer the roasted sweet potatoes into the prepared baking dish. Sprinkle the diced onion and chopped spinach evenly over the top. This layering ensures every bite includes vegetables without sinking or clumping during baking.
Chef’s Tip: Let the sweet potatoes cool for 2–3 minutes so they don’t wilt the spinach immediately.
Step 4: Whisk the Egg Mixture
In the same gray mixing bowl, whisk together the eggs, milk, garlic powder, paprika, and salt for about 30 seconds until fully blended. This mixture binds the casserole and gives it a creamy, custard-like texture when baked.
Chef’s Tip: Whisk until no streaks of egg white remain for a smooth, consistent bake.
Step 5: Assemble the Casserole
Pour the egg mixture evenly over the vegetables. Sprinkle the shredded cheddar cheese across the top, covering the surface without packing it down. Let the dish rest for 2 minutes so the eggs settle between the layers.
Chef’s Tip: Pour slowly around the edges first, then across the center to avoid dry pockets.
Step 6: Bake Until Set
Bake the sweet potato egg casserole at 375°F for 40–45 minutes. You’ll know it’s done when the center no longer jiggles and the top is lightly golden. Rest the casserole for 10 minutes before slicing so it holds its shape.
Chef’s Tip: Insert a knife into the center, if it comes out mostly clean, you’re ready.
