Ingredients

For the Potato Purée:

  • 5 big potatoes
  • 2-3 tbsp butter
  • 1 cup or less whole milk
  • Salt to taste

For the Spinach Mushroom Layer:

  • 1 big onion
  • 4 tbsp olive oil
  • 500g (about 1 lb) spinach
  • 300g (about 2/3 lb) mushrooms
  • Salt, black pepper, red pepper flakes to taste

For the Béchamel Sauce:

  • 3 tbsp olive oil or 2 tbsp butter
  • 2 tbsp all-purpose flour
  • 1 1/2 cups milk
  • Dash of nutmeg
  • Salt to taste
  • Freshly grated kaşar or mozzarella cheese for topping

Instructions

Step 1: Cook The Potato Purée

  1. Peel, wash, and cut the potatoes into cubes.
  2. Boil them in a pan with enough water to just about cover them with a bit of salt.
  3. After about 10 minutes, check to see if the potatoes are cooked using a knife or fork. When the potatoes are soft, drain the water and return the potatoes to the same pan.
  4. While the potatoes are still steaming hot, purée the potatoes using a potato masher.
  5. Add two tablespoons of butter, salt, and one cup of warm milk to the potatoes and mash until a uniform consistency is achieved.

Step 2: Prepare The Spinach and Mushrooms Layer

  1. Dice the onion into small cubes.
  2. Wash and clean the mushrooms and cut into slices. Wash and clean the spinach, take the big stems out and chop them roughly.
  3. Sauté the onion with olive oil in a wide pan until it turns lightly brown.
  4. Once the onions are lightly browned, add the sliced mushrooms, keeping the stove on medium-high heat. Stir from time to time to ensure even cooking.
  5. When the mushrooms are cooked through and there is not much juice in the pan, add the chopped spinach. Season with some salt, freshly ground black pepper, and/or red pepper flakes and stir carefully from time to time until the spinach wilts.

Step 3: Cook The Béchamel Sauce

  1. In a saucepan on low medium heat, add the olive oil or butter and the flour. Stir continuously until you get a nice smell (indicating the flour is not raw anymore) and the color changes from white to slightly golden.
  2. Gradually add the milk to the pan, stirring continuously using a whisk until it thickens. Season with salt and nutmeg.
  3. Turn off the heat after it is thickened and bubbling. If it thickens too much, you can add a bit more milk to adjust the consistency.

Bringing the Spinach Mushroom Potato Casserole Together

  1. Preheat the oven to 180°C (350°F).
  2. Add the béchamel sauce to the spinach and mushroom mixture and check the seasoning (salt, black pepper) and adjust to taste.
  3. Put the mashed potatoes in an oven-safe dish, pressing them down gently to make the first layer. On top of the mashed potato layer, put the spinach, mushroom, and béchamel sauce mixture and spread evenly.
  4. Sprinkle a layer of freshly grated kaşar or mozzarella cheese.
  5. Put the dish into the oven and bake until you have a golden crust on top, about 30 minutes.
  6. When the top is golden brown, turn off the oven and let the casserole rest for 15 minutes before serving.
