Ingredients

You’ll need simple, everyday ingredients to bring this casserole together.

10 oz (280 g) fresh spinach, washed and roughly chopped
7 oz (200 g) feta cheese, crumbled for even distribution
4 large eggs, at room temperature
1 cup (240 ml) whole milk or half-and-half for richness
1 small yellow onion, finely diced
2 cloves garlic, minced
2 tablespoons olive oil
1/2 teaspoon salt
1/2 teaspoon black pepper
1/2 teaspoon dried oregano or thyme
1/4 teaspoon nutmeg, optional but recommended
These ingredients create the classic base of the Easy Feta and Spinach Casserole for Any Meal, delivering flavor without complexity.

Pro Tips

Start by removing excess moisture from the spinach. Even fresh spinach releases water as it cooks, so sauté it briefly and let it cool before mixing. This step keeps the casserole firm and sliceable.
Use high-quality feta. A block of feta packed in brine gives better flavor and creaminess than pre-crumbled versions.
Finally, let the casserole rest after baking. Ten minutes on the counter allows the eggs to set fully, which improves texture and makes serving cleaner. These small techniques elevate the final dish and ensure consistent results every time you prepare this casserole.

Instructions

Step 1
Preheat your oven to 375°F (190°C). Lightly grease a medium baking dish with olive oil and set it aside.

Step 2
Heat olive oil in a skillet over medium heat. Add the diced onion and cook until soft and translucent, about 4 minutes. Stir in the garlic and cook for 30 seconds until fragrant.

Step 3
Add the chopped spinach to the skillet. Cook just until wilted, stirring often. Remove from heat and allow the mixture to cool slightly. Drain any excess liquid if needed.

Step 4
In a large bowl, whisk the eggs, milk, salt, pepper, oregano, and nutmeg until smooth and well combined. This mixture forms the creamy base of the casserole.

Step 5
Fold the cooled spinach mixture into the egg base. Add the crumbled feta and gently stir to distribute evenly without breaking it down too much.

Step 6
Pour the mixture into the prepared baking dish. Spread it evenly so the spinach and feta are well balanced throughout.

Step 7
Bake for 35 to 40 minutes, until the center sets and the top turns lightly golden. A knife inserted in the middle should come out mostly clean.

Step 8
Remove from the oven and let the casserole rest for 10 minutes before slicing. Serve warm or at room temperature for best flavor.

Variations

For a heartier version, add cooked mushrooms or roasted red peppers for extra depth. If you prefer a Mediterranean twist, mix in sliced olives and fresh dill. To make it dairy-light, swap half the feta with ricotta for a softer texture. This recipe also works well as a low-carb option, similar to baked egg casseroles or vegetable-forward dishes like creamy spinach bakes. No matter the variation, the Easy Feta and Spinach Casserole for Any Meal stays versatile and satisfying.

Storage and Serving

Store leftovers in an airtight container in the refrigerator for up to four days. Reheat slices gently in the oven or microwave until warmed through. You can also enjoy it cold as a quick snack. Serve it alongside a fresh green salad, roasted potatoes, or crusty bread for a complete meal. For brunch, pair it with fruit and yogurt. This casserole fits seamlessly into weekly meal plans and special occasions alike.
