Ingredients
- 2 medium sweet potatoes, peeled and cut into small cubes
- 3 cups fresh spinach, roughly chopped
- 6 large eggs
- ½ cup milk
- 1 cup shredded mozzarella cheese
- ½ cup crumbled feta cheese
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 1 tablespoon olive oil
- ½ teaspoon salt, or to taste
- ½ teaspoon black pepper
- ½ teaspoon paprika
- ½ teaspoon dried oregano
- A pinch of chili flakes (optional)
Instructions
1. Prepare the sweet potatoes
Preheat the oven to 375°F (190°C). Peel and cube the sweet potatoes into bite-sized pieces. Toss with half the olive oil, a little salt, and paprika.
2. Roast until tender
Spread the sweet potatoes on a baking tray and roast for 15–20 minutes, until beginning to soften. This helps prevent the finished bake from becoming watery.
3. Cook the spinach
Heat the remaining olive oil in a skillet. Cook the onion for 3–4 minutes, add garlic, and stir for 30 seconds. Add spinach and cook until wilted. Remove excess moisture.
4. Prepare the egg mixture
Whisk the eggs and milk in a bowl. Stir in black pepper, oregano, feta, and half the mozzarella. Taste before adding extra salt because feta is already salty.
5. Assemble the bake
Lightly grease a baking dish. Arrange the roasted sweet potatoes and spinach mixture in the dish. Pour the egg mixture evenly over the vegetables and sprinkle the remaining mozzarella on top.
6. Bake and serve
Bake for 25–30 minutes, or until the eggs are fully set and the center reaches 160°F (71°C). Let rest for 5–10 minutes before cutting into squares.

Questions and answers (Q&A)
Q1. Can I make sweet potato spinach bake without eggs?
Yes. You can try a chickpea-flour batter or a suitable egg substitute, but the texture will be different from a traditional egg casserole.
Q2. Do I need to boil sweet potatoes before baking?
No. Roasting them first is enough for this recipe and helps develop a sweeter flavor.
Q3. Can I use frozen spinach?
Yes. Thaw it completely and squeeze out as much water as possible before adding it to the dish.
Q4. Why is my casserole watery?
The most common reason is excess moisture from spinach or undercooked sweet potatoes. Drain the spinach well and roast the sweet potatoes before assembling.
Q5. Can I prepare it the night before?
Yes. Cook the vegetables and assemble the casserole, cover, and refrigerate overnight. Bake the next day until fully set; it may need a few extra minutes when starting cold.
Q6. Is sweet potato spinach bake good for weight management?
It can fit into a balanced eating plan because it provides protein, fiber, vegetables, and satisfying carbohydrates. Portion size and the amount of cheese and oil will affect the calories.
Q7. Can I add meat?
Yes. Add cooked chicken, turkey sausage, or diced ham. Ensure any meat is fully cooked before mixing it into the casserole.
Q8. What goes well with this bake?
Serve it with a fresh cucumber salad, whole-grain toast, plain Greek yogurt, or roasted vegetables.
