For the Casserole
- Large eggs These provide structure and richness; feel free to substitute with flax eggs for a vegan twist.

- Diced sweet onion For depth and sweetness; shallots or green onions work in a pinch.

How to Make Feta and Spinach Casserole
Preheat your oven to 350 °F. This sets the perfect stage for the casserole to cook evenly and achieve that golden top. Give it a moment to heat up while you prepare the other ingredients.
Grease a 1 & 1/2-quart (9-inch square) casserole dish with a bit of butter or cooking spray. This will help the casserole slide out effortlessly once it s baked, making serving a breeze.
Combine all the ingredients in a large mixing bowl: beaten eggs, cottage cheese, thawed spinach, crumbled feta, diced onion, melted butter, Parmesan, black pepper, garlic powder, and nutmeg. Mix well until smooth and blended together, ensuring every flavor is represented.
Transfer the mixture into the greased casserole dish. Spread it out evenly with a spatula to ensure even cooking and the perfect texture throughout.
Bake uncovered for about 40-45 minutes, or until the center is nearly set and the edges start to turn golden brown. You ll know it s ready when a toothpick inserted comes out clean, promising a delicious, fluffy casserole.
Cool for 5-10 minutes before cutting into it. This resting time allows the casserole to firm up a bit, making each serving a luscious, satisfying piece. Serve warm and enjoy the delightful flavors!
Optional: Top with fresh herbs like parsley for a burst of color and flavor!

Feta and Spinach Casserole Recipe FAQs
How do I select the best spinach for my casserole?
Absolutely! For the best results, I recommend using frozen chopped spinach that is well-drained to avoid excess moisture in your casserole. If you prefer fresh spinach, choose vibrant, dark green leaves without dark spots or wilting. Make sure to wash it thoroughly, saut it briefly until wilted, and drain it well before adding it to the casserole mixture.
How should I store any leftovers from my Feta and Spinach Casserole?
Very easy! Store your leftovers in an airtight container in the fridge for up to 3 days. This will keep your casserole fresh and ready for a quick meal later. Just make sure to let it cool completely before sealing it up to prevent moisture buildup, which can lead to sogginess.
Can I freeze Feta and Spinach Casserole?
Yes, you can! To freeze your casserole, first let it cool completely. Wrap it tightly in plastic wrap, then in aluminum foil, making sure it s sealed to prevent freezer burn. You can freeze it for up to 3 months. When you re ready to enjoy it again, simply thaw it overnight in the fridge and reheat in the oven at 350 °F for about 20-25 minutes until heated through.
What can I do if my casserole is too watery after baking?
Oh no! If your casserole comes out a bit watery, it s often because excess moisture was in the spinach or if it wasn t drained well enough. For future bakes, ensure that your spinach is thoroughly drained, pressing it with paper towels if necessary. If you find yourself in a jam, you can mix in a little extra cottage cheese or a small handful of breadcrumbs to absorb the moisture.
Is this recipe suitable for people with allergies?
Great question! This recipe includes dairy products such as cottage cheese and feta, so it may not be suitable for those with lactose intolerance or a dairy allergy. For a dairy-free version, consider using non-dairy cheese or a mixture of silken tofu and nutritional yeast to mimic the flavors. It s always best to double-check ingredient labels for any specific allergens, especially if you re serving guests!
Can pets enjoy a little bit of this casserole too?
While it s always sweet to share, I recommend keeping this casserole away from your furry friends. The ingredients include onion and garlic powder, which can be toxic to pets. It s best to stick to treats specifically designed for them, ensuring they re safe and healthy!
