A chicken and spinach egg casserole is a baked egg-based dish that combines shredded or diced chicken with spinach, cheese, and seasonings. It’s similar to a crustless quiche—high in protein, naturally low in carbs, and full of fresh flavor.

Ingredients

Scale

2 cups cooked chicken, shredded or diced (rotisserie chicken works great)
8 large eggs
1 cup milk (or almond milk for a lighter version)
1 ½ cups shredded mozzarella or cheddar cheese
2 cups fresh spinach (roughly chopped)
1 small onion, finely diced
2 cloves garlic, minced
1 teaspoon salt
½ teaspoon black pepper
½ teaspoon paprika (optional for color)
1 tablespoon olive oil or butter (for sautéing)
1 tablespoon butter (for greasing the baking dish)

Instructions

Step 1: Preheat oven

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or non-stick spray.

Step 2: Sauté vegetables

In a skillet, heat olive oil over medium heat. Add diced onion and minced garlic, and cook for 2–3 minutes until fragrant. Add chopped spinach and cook until wilted. Remove from heat and set aside.

Step 3: Prepare egg mixture

In a large bowl, whisk together eggs, milk, salt, pepper, and paprika until well combined and slightly frothy.

Step 4: Assemble the casserole

Spread the cooked chicken evenly in the prepared baking dish. Add the sautéed spinach mixture over the chicken, then pour the egg mixture evenly across the top. Sprinkle shredded cheese over everything.

Step 5: Bake casserole

Bake uncovered for 35–40 minutes, or until the eggs are set and the top is lightly golden.

Step 6: Rest and serve

Let the casserole rest for 5–10 minutes before slicing. Garnish with extra spinach or herbs if desired and serve warm.
