I made this spinach pie recipe the other day for our family and my gluten-free friend, and it was so good. My friend told me she finally had a gluten-free option for a spanakopita-like dish, which she has missed since adopting a gluten-free diet.

The beauty of this high-protein crustless spinach and feta casserole recipe is that you can use any flour you like, including all-purpose flour. I ate it for dinner, breakfast and lunch, so you might want to double the recipe to have some great leftovers! Plus, check out the health benefits of protein.

To make this crustless, gluten-free Greek-inspired recipe you will need olive oil, green onions or shallots, fresh or frozen spinach, flour of choice, baking powder, sea salt, milk of choice, eggs, butter, fresh dill, mozzarella cheese, feta cheese and Parmesan cheese.

You can prepare the recipe the day before and refrigerate it, covered, then bake the following day. This casserole recipe also bakes very nicely as muffins, but make sure to decrease the cooking time by half to see if they are cooked. My photos show a doubled recipe baked in a 13x9-inch baking pan.

Serve this Greek casserole for breakfast, brunch, lunch or a vegetarian dinner with your favorite side dishes. You could even serve this as a side dish with your favorite protein. 

Cuisine: Greek
Prep Time: 15 minutes
Cook Time: 40 to 45 minutes
Total Time: 55 to 60 minutes
Servings: 6

Ingredients

• 2 teaspoons olive oil
• 4 green onions or 2 shallots, chopped (I did a combination)
• 12 ounces baby spinach, fresh or frozen, roughly chopped (if frozen, defrost first)
• 1 cup all-purpose flour, oat flour, almond flour or a gluten-free flour blend (I used Bob’s Red Mill gluten-free flour blend)
• 1 teaspoon baking powder
• 1 teaspoon sea salt
• 1 cup milk (almond, coconut, soy or regular)
• 2 large eggs, lightly beaten
• 2 tablespoons unsalted butter, melted
• 2 tablespoons fresh dill, chopped
• 4 ounces shredded mozzarella
• 4 ounces feta cheese
• 2 tablespoons grated Parmesan cheese

Here's how to make it: 

1. If you are using fresh spinach, place a frying pan on the stove on medium heat with a few tablespoons of water. Place your spinach and wilt it down stirring with a spatula every now and then.
   
2. Place the fresh cooked or defrosted frozen spinach in a colander and squeeze out excess moisture. Be careful with the fresh spinach as it will be hot. Use a clean towel or paper towel to press out as much moisture as possible. Set aside.
   
3. Using the same frying pan, add green onions or shallots and olive oil. Cook on medium heat for 2 minutes.
   
4. While the green onions cook, add the flour, salt and baking powder to a mixing bowl. Use a fork to gently blend.
   
5. Add the milk, eggs and melted butter. Blend. (If you use a plant-based milk, make sure it is unsweetened.)
   
6. Add the green onions, dill, feta, mozzarella and spinach. Blend well.
   
7. Put the batter into a parchment paper-lined 8x8-inch baking pan and press it into the corners. Smooth the top with a spatula. Sprinkle the top with Parmesan cheese.
   
8. Bake in a preheated 375-degree F oven for 40 to 45 minutes. Remove when you press gently on the top and it springs back. Remove and cool for 10 to 15 minutes.
   
9. Cut, serve and enjoy! Store any leftovers in an airtight container in the fridge and reheat in the microwave.
