How to Make Easy Feta and Spinach Casserole Recipe
Step 1: Prep Your Spinach
If you’re working with frozen spinach, make sure to thaw it fully and squeeze out every bit of excess moisture—this prevents a watery casserole. For fresh spinach, chop and sauté it until just wilted, then allow it to cool before mixing. This first step ensures your greens contribute a lush texture without sogginess.
Step 2: Sauté Onion and Garlic
Warm the olive oil in a skillet over medium heat, then add your finely chopped onion and cook until it becomes soft and translucent, about 5 to 6 minutes. Stir in the minced garlic and cook for just 30 seconds more to avoid burning, releasing its fragrant bouquet. Let this mixture cool slightly before combining with other ingredients, so it doesn’t cook the eggs prematurely.
Step 3: Whisk the Egg Mixture
In a large bowl, whisk together the 5 large eggs and the half cup of milk or half-and-half until smooth and slightly frothy. This creates the creamy custard base of your casserole that will gently set around the spinach and feta, yielding a light but rich texture.
Step 4: Combine All Ingredients
Add the spinach, sautéed onions and garlic, crumbled feta, and seasonings like salt, pepper, and the gentle hint of nutmeg to the egg mixture. If you’re using fresh chopped herbs, toss those in here too. Stir everything together carefully but thoroughly—this ensures that every bite has a perfect harmony of flavors.
Step 5: Prepare for Baking
Preheat your oven to 375°F (190°C). Lightly grease an 8 by 8-inch baking dish to prevent sticking and provide a nice crust on the edges. Pour the combined mixture into the dish and smooth the top with a spatula, setting yourself up for an even bake with a golden finish.
Step 6: Bake to Perfection
Bake the casserole for 35 to 40 minutes until the top turns a beautiful golden color and the center is fully set. You can test doneness by inserting a knife into the middle; if it comes out clean, your casserole is ready. Let it rest for 5 to 10 minutes after pulling it from the oven to firm up before slicing and serving.
How to Serve Easy Feta and Spinach Casserole Recipe
Garnishes
A sprinkle of freshly chopped parsley or dill not only adds a burst of color but also enhances freshness with each forkful. You might also try a light dusting of paprika or a little extra crumbled feta on top for that final savory touch.
Side Dishes
This casserole pairs wonderfully with simple sides like a crisp green salad dressed with lemon vinaigrette or some crunchy toasted bread that’s perfect for scooping. If you want to round out a meal, consider serving alongside roasted potatoes or a light tomato salad for complementary textures and flavors.
Creative Ways to Present
For a brunch spread, cut the casserole into bite-sized squares and present on a wooden board with an assortment of fresh vegetables and dips. Another fun idea is layering this casserole between slices of toasted sourdough bread for a gourmet sandwich experience that will have friends asking for your Easy Feta and Spinach Casserole Recipe!
Make Ahead and Storage
Storing Leftovers
Once cooled, cover the casserole tightly with plastic wrap or place it in an airtight container and store in the refrigerator for up to 3 days. This makes it a perfect recipe to prepare in advance for busy weeknights or make-ahead breakfasts.
Freezing
You can freeze leftover portions by wrapping them tightly in plastic wrap and aluminum foil, then storing in a freezer-safe container for up to 2 months. Defrost in the fridge overnight before reheating for the best texture and flavor retention.
Reheating
To reheat, either warm individual slices in the microwave for about 1 to 2 minutes or heat in a 350°F oven for 10 to 15 minutes until warmed through and the top regains a bit of crispness. The casserole holds up beautifully, retaining its creamy, cheesy goodness.
FAQs
Can I use fresh spinach instead of frozen?
Absolutely! If you use fresh spinach, just remember to sauté it until wilted and then cool it before adding to avoid excess moisture. This keeps your casserole from becoming soggy.
Is there a dairy-free version of this casserole?
You can substitute the milk or half-and-half with a dairy-free alternative like almond or oat milk and swap feta for a vegan cheese, but keep in mind the flavor profile will be a bit different. Using firm tofu mashed with lemon and herbs can be a great feta replacement too.
Can this recipe be doubled for a larger crowd?
Yes! Simply double all the ingredients and bake in a larger dish, adjusting baking time accordingly—usually around 45 to 50 minutes—to ensure it cooks evenly through the center.
What herbs pair best with this casserole?
Fresh dill and parsley are classic companions that bring brightness without overpowering the feta and spinach. You could also experiment with chives or thyme for a slightly different flavor twist.
Is this casserole suitable for meal prep?
Definitely. The Easy Feta and Spinach Casserole Recipe keeps well in the fridge and reheats beautifully, making it a fantastic choice for planning meals ahead or packing for work or school lunches.
