Spinach and feta are truly one of those great food combinations. We see it in the famous spanakopita where they are combined along with crunchy phyllo but also with spanakorizo the traditional Greek spinach and rice dish which must be eaten with a chunk of feta.

Spinach is one of those much loved leafy vegetables, it’s added in pasta, in dips and in salads. Cooking it, as is done mostly in Greek and Mediterranean cuisine, has the added benefit of shrinking, that means that it is easier to eat much more!

The Flavors of Spanakopita in a Casserole

This dish came about because I was looking to make a somewhat easy dish that included 2 of my favorite ingredients: feta and spinach. Oh and it had to be easy! So what about a spinach casserole but healthier and more Mediterranean? I used ingredients typically used in a spanakopita along with parmesan and a few eggs as well as herbs. Because there is no phyllo, I felt it needed something starchy to give it a bit more texture and substance, so I made this easy topping. I used whole grain wheat and barley breadcrumbs and mixed them with some olive oil with a fork until I had a coarse meal, similar to the method used to make a streusel topping. I basically made a gratin and it took less than 30 minutes!

The result was not only pretty but delicious! In every bite you get melted cheese along with flavorful spinach and herbs and the crunchy topping. And this is in fact a healthy dish as opposed to many spinach casseroles that contain cream, butter, and lot of cheese. This felt filling and rich but not heavy.

We had this for lunch, but it would make a great breakfast or brunch dish. It combines everything you need: vegetables, protein, good fats and flavor. You can assemble it the night before and just bake it the next morning.

Spinach Nutrition

There have been several studies examining the nutrients in spinach. Generally (thanks to Popeye) we associate spinach with iron. Yes, spinach contains iron although many factors affect how much you actually absorb. Cooked spinach increases the amount of iron and calcium available for absorption. There is also the issue of oxalic acid, this is an inhibitor that is believed to block the absorption of iron and calcium. However when spinach is cooked, the oxalic acid is broken down and does not block the absorption of nutrients.

The absorption of iron can be increased when consumed with vitamin C rich foods such as squeezing some lemon or accompanying with a small tomato salad.

Research has also shown that although there is loss of some nutrients in vegetables when cooked (such as vitamin K), in many instances fat soluble vitamin levels are increased as well as the antioxidant ability.

Apart from iron,  spinach is a good source of vitamins, A and C, folate, magnesium, and calcium.

  • 1 pound 450 grams fresh spinach washed and chopped (or about 7 ounces or 200 grams frozen defrosted and drained)
  • 6 spring onions sliced (only whites)
  • 8 ounces 240 grams crumbled feta
  • 4 tablespoons grated parmesan
  • 3 tablespoons olive oil
  • 1 ½ tablespoon dry oregano
  • ¼ cup dill chopped
  • salt/pepper
  • 1 tablespoon breadcrumbs (preferable wholegrain)
  • 6 medium eggs
  • *Lemon for serving

For Topping

  • 3 tablespoons breadcrumbs
  • 1 tablespoon olive oil


  • Preheat oven at 400 F (200 C)
  • Brush a 8×12 inch (20-30 cm) baking dish with olive oil.
  • In a large deep pan or pot heat 2 teaspoons of olive oil and sauté the spring onions for 2-3 minutes, add the spinach and continue heating until spinach wilts and shrinks. Remove from pan, strain and let it cool.
  • In a large bowl mix the feta cheese, 2 tablespoons parmesan, 1 tablespoon bread crumbs, oregano, dill, 1 tablespoon olive oil, a pinch of salt and freshly ground pepper. Add the spinach and mix making sure it has spread in the whole mixture.
  • In a small bowl whip the eggs and add them to the spinach mixture and mix well.
  • Grease a baking dish with olive oil and transfer the spinach mixture to the baking dish. Even it out and sprinkle over it the rest of the parmesan (2 tablespoons).
  • Make topping: in a small bowl place the rest of the bread crumbs (3 tablespoons), and add olive oil gradually (do not add all of it at once) while pressing the mixture with a fork, add enough olive oil until you have a crumbly texture and all the breadcrumbs are wet. Sprinkle over the casserole.
  • Bake in the oven for about 15 minutes. After that, put under broiler about 1-2 minutes until topping is golden (check often).
  • Let it cool and serve.
  • You may serve with a squeeze of lemon.


Make Ahead:
Assemble it the night before (except for the topping), transfer to the baking dish and cover tightly with aluminum foil and place in refrigerator for one night. To Bake: Make the topping and sprinkle and bake.
You can also assemble and freeze (uncooked) for 3 months. To bake you must let it defrost first.
You can also freeze after cooking and heat when ready to serve.

    This spinach casserole is delicious! I love the combination of flavors and the topping is perfect.

    I made this with gluten free bread crumbs and it turned out just fine. I’m sure it would also work as a kosher for Passover dish using matzo meal. I used an oven-safe pan to have one less dish to wash, and that worked well.5 stars

    I have also made this with equivalent weight of shredded zucchini (and GF bread crumbs) when my frozen garden spinach was gone and it was equally good. I’m tempted to try leeks next.5 stars

    Can you use fresh spinach in this? I have a container in the fridge that’s why I came looking for recipes.

  • Reply Jean April 15, 2022 at 5:00 pm

    If the casserole is refrigerated overnight, do the baking instruction change?

      Hello, how many mushrooms did you add? Did you add them raw to bake? or did you sautee them first?

  • Reply Gemma December 1, 2021 at 2:42 pm

    Great recipe. I was worried it’d be overly eggy as my partner hates eggs but he loved it. Pretty healthy too – we had it as 6 portions instead of 4 and served with lots of veggies.5 stars

    I wanted to make something quick and easy using up spinach and this did not disappoint! Very tasty and cooked in next to no time. Will definitely do again.5 stars

    Hi Cindy,

    Violife do a great vegan Feta which i’ve substituted into this recipe. The cheese itself is called “greek white”. Lower salt than the real thing.5 stars

    I made this over the weekend and it was amazing. I recently discovered your blog and am very excited to cook many of your recipes. I also appreciate that you provide information regarding the nutrition value of the (main) ingredients and the science behind. Thank you!

    I really want to make this recipe for hubby and I soon. He has high blood pressure and while at store noticed feta is very high in salt. I want to start cooking Mediterranean style. Is there a substitute for the feta cheese or is there another type of cheese Greeks enjoy lower in salt. Thank you for your quick reply.

      You can reduce the salt in the feta cheese by soaking a block of cheese in water for a couple hours ( changing the water a few times) . This is how we eat our feta, it has a mild salty taste not overpowering.
