Mediterranean Creamy Crustless Chicken & Spinach Cheese Casserole
This Mediterranean Creamy Crustless Chicken & Spinach Cheese Casserole is comfort food with a lighter, fresher feel. It takes familiar ingredients like tender chicken, wilted spinach, eggs, and cheese, then layers them with Mediterranean flavors that feel both cozy and vibrant. Because there’s no crust, the casserole stays naturally low-carb and gluten-free while still delivering a rich, satisfying texture.
It works beautifully for busy weeknights, meal prep, or a relaxed weekend brunch. The chicken makes it filling, the spinach keeps it balanced, and the cheese ties everything together into a creamy, savory bake that slices cleanly and reheats well. It’s the kind of recipe that feels dependable, flexible, and always welcome at the table.
Prep time: 20 minutes
Cook time: 35 minutes
Resting time: 10 minutes
Total time: 1 hour 5 minutes
Ingredients
Olive oil: 2 tablespoons
Onion: 1 medium, finely chopped
Garlic: 3 cloves, minced
Cooked chicken breast: 2 cups, diced or shredded
Fresh spinach: 5 cups, loosely packed
Eggs: 6 large
Heavy cream or half-and-half: 1 cup (240 ml)
Shredded mozzarella cheese: 1 cup
Crumbled feta cheese: ½ cup
Grated Parmesan cheese: ¼ cup
Dried oregano: 1 teaspoon
Dried basil: ½ teaspoon
Paprika: ½ teaspoon
Salt: ¾ teaspoon, or to taste
Black pepper: ½ teaspoon
Fresh parsley: 2 tablespoons, chopped
Instructions
Preheat the oven to 375°F (190°C). Lightly grease a 9×9-inch baking dish or similar size casserole dish.
Heat olive oil in a large skillet over medium heat. Add the chopped onion and sauté for 3–4 minutes until softened.
Stir in the garlic and cook for about 30 seconds until fragrant.
Add the cooked chicken to the skillet and warm it through for 2–3 minutes, stirring to coat with the aromatics.
Add the spinach in batches, letting it wilt before adding more. Cook just until fully wilted, then remove from heat.
Let the mixture cool slightly and drain off any excess liquid to keep the casserole from becoming watery.
In a large bowl, whisk together the eggs, cream, Parmesan cheese, oregano, basil, paprika, salt, and black pepper until smooth.
Fold the chicken and spinach mixture into the egg mixture, mixing gently until evenly combined.
Stir in the mozzarella and most of the feta, reserving a little feta for the top.
Pour the mixture into the prepared dish, sprinkle with remaining feta, and bake for 30–35 minutes until set and lightly golden. Let rest for 10 minutes before slicing.
Tips
Use rotisserie chicken for extra flavor and convenience.
Make sure spinach is well-drained to avoid excess moisture.
Let hot ingredients cool slightly before adding eggs.
Full-fat dairy creates the creamiest texture.
Taste feta before adding extra salt, as it’s naturally salty.
Resting the casserole helps it firm up for clean slices.
A glass or ceramic dish bakes more evenly than metal.
Add fresh herbs at the end for brighter flavor.
Don’t overbake, as eggs can become rubbery.
Store leftovers tightly covered to keep them moist.
Variations
Add sun-dried tomatoes for a sweet, tangy note.
Swap mozzarella for provolone or Monterey Jack.
Use ground chicken or turkey instead of diced chicken.
Add mushrooms for extra depth and earthiness.
Replace spinach with kale or Swiss chard.
Make it spicy with chili flakes or harissa.
Use ricotta instead of cream for a lighter version.
Add olives for a briny Mediterranean touch.
Turn it into individual ramekins for portion control.
Top with sliced tomatoes before baking for added freshness.
