KEY INGREDIENTS IN PROTEIN-PACKED SWEET POTATO EGG CASSEROLE
Before diving into the step-by-step process, let’s look at what makes this casserole shine. Each ingredient plays a crucial role, from adding flavor layers to offering nutritional benefits. Here’s a closer look at the stars of the show:
- Sweet potatoes
These bring a natural sweetness and hearty texture, roasting to tender perfection and forming the flavorful base of the casserole.
- Olive oil
Used to coat the sweet potatoes, it helps achieve golden-brown edges while contributing healthy fats and a smooth mouthfeel.
- Salt
Essential for enhancing each ingredient’s natural flavors and balancing the dish’s sweet and savory notes.
- Black pepper
Adds a gentle spicy kick, brightening the overall taste without overpowering the other seasonings.
- Eggs
The protein powerhouse that binds everything together, providing a fluffy, silky custard that holds the casserole in place.
- Milk (or preferred milk substitute)
Lightens the egg mixture for a custardy texture, ensuring the bake remains moist and tender.
- Garlic powder
Delivers a warm, savory undertone that complements the sweet potatoes and feta cheese.
- Onion powder
Infuses a mild, savory depth, building complexity in every bite.
- Paprika
Contributes subtle smokiness and a hint of color, making the top of the casserole invitingly golden.
- Spinach leaves
Brings a pop of vibrant green and a boost of vitamins, folding into the egg mixture for a fresh, earthy element.
- Cherry tomatoes
Offer juicy bursts of tangy sweetness, balancing out the richer flavors in the dish.
- Feta cheese
Crumbled on top for a tangy, salty contrast that cuts through the creamy eggs and sweet potatoes.
- Fresh parsley
Sprinkled as a finishing touch, it lends a bright herbal note and a delightful visual pop.
HOW TO MAKE PROTEIN-PACKED SWEET POTATO EGG CASSEROLE
Let’s roll up our sleeves and transform these ingredients into a comforting, protein-rich casserole. Follow these steps, and you’ll have a nutritious breakfast or lunch ready in under an hour.
1. Preheat the oven to 400°F (200°C). This high initial heat will help the sweet potatoes develop a caramelized exterior.
2. Toss the sweet potatoes on a baking sheet with olive oil, salt, and pepper. Coating them evenly ensures each cube roasts to crispy, golden perfection.
3. Roast the sweet potatoes for 20–25 minutes, until they’re tender when pierced and have a light, browned crust. The smell of caramelizing sugars is a good cue they’re ready.
4. While they roast, whisk together eggs, milk, garlic powder, onion powder, and paprika in a large bowl. Aim for a smooth, uniform mixture—this is the base of your casserole’s custard.
5. Once the sweet potatoes are done, reduce the oven temperature to 350°F (175°C). This gentler heat will set the eggs without overbrowning the top.
6. Grease a 9×13-inch baking dish with oil or nonstick spray. Spread the roasted sweet potatoes in an even layer across the bottom.
7. Scatter the chopped spinach, halved cherry tomatoes, and crumbled feta over the sweet potatoes. This creates colorful pockets of flavor throughout the bake.
8. Pour the egg mixture evenly over the vegetables and cheese, ensuring everything is submerged.
9. Use a spatula to gently press and distribute the ingredients, making sure each piece of sweet potato and vegetable is coated.
10. Bake for 25–30 minutes, until the eggs are fully set in the center and the top turns a golden-brown hue. A toothpick inserted in the middle should come out mostly clean.
11. Remove from the oven and let the casserole rest for a few minutes—this helps the custard finish cooking and makes slicing neater.
12. Garnish with chopped fresh parsley before serving for a final touch of color and freshness.
