How To Make the Easy Feta and Spinach Casserole

Step 1: Prep the Oven and Pan

Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish with butter or nonstick spray.

Step 2: Prepare the Spinach

If using frozen spinach, thaw and squeeze out all excess water. For fresh, sauté it quickly until wilted and then chop roughly.

Step 3: Mix the Ingredients

In a large bowl, whisk together eggs until smooth. Add crumbled feta, cottage cheese, spinach, chopped onions, garlic (if using), salt, and pepper. Mix thoroughly to combine.

Step 4: Transfer to Baking Dish

Pour the mixture into your prepared baking dish and smooth the top with a spatula.

Step 5: Bake

Bake uncovered for 35-40 minutes or until the top is golden and the center is set. Let it cool for 5-10 minutes before slicing.
