Ingredients

• 4 large Russet potatoes
• 4 tablespoons Butter
• 1 cup Milk
• 6 cups Fresh spinach
• 1 cup Feta cheese
• 1.5 teaspoons Salt
• 0.5 teaspoon Black pepper
• 1 tablespoon Olive oil
• 2 cloves Garlic
• 0.5 cup Parmesan cheese
• 2 large Eggs

Directions

Step 1

Peel and chop the russet potatoes into 1-inch chunks. Place them in a large pot, cover with water, and add a pinch of salt. Bring to a boil and cook until the potatoes are fork-tender, about 15-20 minutes.

Step 2

While the potatoes are cooking, heat the olive oil in a large skillet over medium heat. Mince the garlic and add it to the skillet. Cook for 1-2 minutes until fragrant.

Step 3

Add the fresh spinach to the skillet and cook until wilted, about 3-5 minutes. Remove from heat and let cool slightly.

Step 4

Preheat the oven to 375°F (190°C) and grease a 9x13-inch casserole dish with butter or cooking spray.

Step 5

Once the potatoes are cooked, drain them and return them to the pot. Add the butter, warm milk, salt, and black pepper. Mash the potatoes until creamy and smooth.

Step 6

Stir in the wilted spinach and crumbled feta cheese, mixing until evenly distributed.

Step 7

In a small bowl, beat the eggs and then fold them into the potato mixture. This will help the casserole set during baking.

Step 8

Transfer the mashed potato mixture into the prepared casserole dish and spread it evenly.

Step 9

Sprinkle the grated Parmesan cheese evenly over the top of the casserole.

Step 10

Bake in the preheated oven for 25-30 minutes, or until the top is golden and slightly crispy.

Step 11

Allow the casserole to cool for 5-10 minutes before serving. Enjoy as a hearty side dish or a vegetarian main course.
