Tips & Variations
- Swap dried oregano for fresh dill, parsley, or basil to change the flavor profile.
- Add roasted red peppers, sun-dried tomatoes, or olives for a Mediterranean twist.
- For extra protein, mix in cooked chicken, ham, or turkey.
- Use a gluten-free baking blend instead of all-purpose flour for a gluten-free version.
- Include additional cheese like mozzarella, gouda, or cheddar for more cheesiness.
Storage
Store Spinach Feta Bake Squares in an airtight container in the refrigerator for up to 3 days. For longer storage, freeze individual squares wrapped in foil or parchment paper for up to 2 months.

FAQs
Can I use frozen spinach instead of fresh?
Yes, just thaw the frozen spinach and squeeze out excess moisture before cooking. It works just as well and makes the recipe convenient year-round.
Can I make this recipe dairy-free?
To make it dairy-free, substitute feta and other cheeses with your favorite plant-based cheeses and use a non-dairy milk such as almond or oat milk. The texture and flavor will differ slightly but will still be tasty.

Instructions
- Preheat Oven and Prepare Pan: Preheat your oven to 180°C (350°F). Lightly grease a square baking dish or line it with parchment paper to ensure easy removal of the bake squares.
- Sauté Vegetables: Heat 1 tablespoon of olive oil in a skillet over medium heat. Add the finely chopped onion and minced garlic, cooking until they become soft and fragrant. Next, add the spinach—if fresh, cook until wilted; if using frozen, cook until most moisture evaporates. Remove from heat and let the mixture cool slightly.

- Add Dry Ingredients: To the wet mixture, stir in the all-purpose flour, baking powder, salt, ground black pepper, and dried oregano or dill. Mix thoroughly until you achieve a thick but pourable batter.
- Combine Spinach Mixture and Cheese: Fold the cooled spinach, onion, and garlic mixture into the batter along with the crumbled feta cheese. If desired, add the grated mozzarella or Parmesan now for an extra cheesy flavor.
- Pour and Smooth Batter: Pour the combined batter evenly into the prepared baking dish. Use a spatula to smooth the surface into an even layer for uniform baking.
- Bake: Place the dish in the preheated oven and bake for 35 to 40 minutes, or until the top is golden brown and the center is set and no longer jiggly.
- Cool and Serve: Remove from the oven and allow the bake to cool for at least 10 minutes. Cut into squares and serve warm, at room temperature, or chilled, depending on your preference.
