How to Make Spinach and Feta Egg Casserole Recipe
Step 1: Preheat and prepare
Start by heating your oven to 375 degrees Fahrenheit and greasing your casserole dish thoroughly. This ensures your casserole will cook evenly and easily release from the dish later.
Step 2: Sauté the onions
Warm the olive oil in a medium skillet over medium heat, then add the diced onions. Let them cook for about 5 to 7 minutes until they become soft and translucent. This step is key to unlocking the onions’ natural sweetness and building a tasty base.
Step 3: Wilt the spinach
Once the onions are ready, add the baby spinach to the skillet. Cook for an additional 2 to 3 minutes until wilted but still vibrant green. This quick cooking helps preserve the spinach’s nutrients and freshness while blending its flavors with the onions.
Step 4: Prepare the egg mixture
In a large bowl, whisk together the eggs, milk, salt, and freshly ground black pepper until combined smoothly. Gently fold in the crumbled feta cheese, which will add pops of salty creaminess throughout the casserole.
Step 5: Assemble the casserole
Spread the sautéed spinach and onion mixture evenly across the bottom of your prepared casserole dish. Pour the egg and feta mixture over the top, creating an inviting layer that promises rich, fluffy bites once baked.
Step 6: Bake to perfection
Place your casserole in the oven and bake for 30 to 35 minutes. You’ll know it’s ready when the eggs have fully set and the top turns a light golden color, signalling that the flavors have married beautifully and the texture is just right.
Step 7: Rest and serve
Once out of the oven, allow the casserole to rest for a few minutes. This brief wait helps it finish setting and makes slicing cleaner and easier, so each serving stays intact and looks as wonderful as it tastes.
How to Serve Spinach and Feta Egg Casserole Recipe
Garnishes
Fresh herbs like chopped dill or parsley work wonderfully as garnishes, adding a burst of color and a subtle herbal note. A sprinkle of extra feta or a dash of smoked paprika on top can also elevate the presentation and flavor dimension.
Side Dishes
This casserole pairs delightfully with crisp, fresh salads for balance. Try a simple arugula salad with lemon vinaigrette or tomato and cucumber salad to keep things light and refreshing alongside the rich egg bake.
Creative Ways to Present
Serve individual casserole portions in small ramekins or muffin tins for charming single servings perfect for brunch gatherings. You can also layer this casserole over toasted rustic bread and serve it open-faced with a drizzle of olive oil for a rustic yet elegant twist.
Make Ahead and Storage
Storing Leftovers
Leftover casserole can be stored in an airtight container in the refrigerator for up to 3 days. This makes it a fantastic option for quick breakfasts or lunches throughout the week without sacrificing flavor or texture.
Freezing
You can freeze individual portions by wrapping them tightly in plastic wrap and placing them in a freezer-safe container or bag. This Spinach and Feta Egg Casserole Recipe keeps well frozen up to 2 months, perfect for planning ahead.
Reheating
When ready to enjoy leftovers, reheat portions gently in a microwave or oven until just warmed through. Avoid overheating to keep the eggs from drying out and the feta from becoming rubbery; a low heat setting works best.
FAQs
Can I use frozen spinach instead of fresh?
Yes, you can substitute frozen spinach; just make sure to thaw it fully and squeeze out any excess moisture before cooking to maintain the casserole’s texture.
Is this casserole suitable for meal prep?
Absolutely. It reheats well and tastes just as good after a few days, making it ideal for preparing in advance and enjoying during a busy week.
Can I add other vegetables to the casserole?
Definitely! Feel free to mix in diced bell peppers, mushrooms, or tomatoes for extra flavor and color, adjusting cooking times slightly if needed.
What type of feta cheese works best?
A good quality, crumbled feta that’s not overly briny pairs best here. Choose one that balances saltiness with creaminess to complement the spinach and eggs perfectly.
How do I know when the casserole is fully cooked?
The casserole is done when the eggs are set firm, no longer jiggly in the center, and the top has a gentle golden hue. A toothpick inserted should come out clean.
