This delicious Spinach Casserole recipe with feta cheese will be a winner with even the pickiest eaters. Gluten free, low carb, and vegetarian, making it a great breakfast, brunch, side dish, or main if you need to accommodate special diets. And it’s so easy to make!
Love spinach? Don’t miss our classic Creamed Spinach! So delicious and goes with just about anything.

Have you ever made Spanakopita? It’s a Greek classic, featuring spinach, feta cheese, herbs, and butter, stuffed into flaky phyllo shells. This Spinach Casserole is very similar, except made with cottage cheese and without the pastry.
This casserole is great served for breakfast, brunch, as a side, or a perfect vegetarian main dish if you need something meatless.
Friends who are not fond of spinach love this dish and always ask for the recipe. It goes well with any meat or fish and is hearty and satisfying!
Spinach Casserole Recipe
You only need a few simple ingredients to make this casserole.
(Scroll below to the printable recipe card for details and measurements.)
- Spinach: We use frozen, thawed chopped spinach. (See note below regarding fresh spinach.)
- Cottage cheese: This is milky, sweet, and mellow, similar to ricotta. As the casserole bakes, it breaks down and adds necessary moisture, making the casserole creamy.
- Feta cheese: Crumbled feta adds a nice salty flavor.
- Sweet onion: For flavor.
- Large eggs: Eggs act as a binder to hold everything together.
- Butter: For flavor and richness.
- Seasoning: Black pepper, garlic powder, and nutmeg.

How to Make Spinach Casserole
With just one bowl, it seriously could not be easier to make this Spinach Breakfast Casserole.
(Don’t miss the complete printable recipe card below, along with the video.)
- Combine all the ingredients in a bowl.
- Transfer to a greased casserole dish.
- Bake until set and enjoy.
Recipe Variations
- Use fresh spinach: Fresh spinach can be used instead of frozen, keeping in mind 1 1/2 cups of cooked fresh spinach is roughly the equivalent of a 10 ounce frozen package.
- Try ricotta cheese instead: If you really hate cottage cheese, you can use ricotta in its place.
- Sauté the onions first: If you’ve got the time, sautéing the onions before adding them to the mix, will add more flavor.
- Add in some artichokes: Love the flavor of spinach artichoke dip? Us, too! Mix in some jarred, drained and chopped artichoke hearts.
- Include other seasoning: Stir in a 1/4 teaspoon of dried dill for added flavor. Or a pinch of crushed red pepper flakes if you want some heat.

Storing Leftovers
Assembled ahead of time: You can assemble this casserole up to 1 day ahead and store, tightly covered, in the refrigerator. Bring to room temperature and then bake.
To store leftovers, cool completely, then store in an airtight container in the fridge up to 3 days.
Can you freeze spinach casserole? I do not recommend freezing this casserole, since the spinach mixture tends to be watery once thawed.

What to Serve with Spinach Cottage Cheese Casserole
This dish is so flavorful, but mild enough that it goes well with any meat or fish. We love it with Baked Chicken Breast and Beef Brisket. Also nice with a bowl of Fresh Fruit Salad.

Other Notes

Just lovely and delicious. So nice to have a low carb breakfast/side option. Will make this again.
Absolutely delicious – thank you!
Great recipe! I added in a glove of minced garlic and diced fresh mushrooms.
I needed something for a brunch that could accomodate gluten free and also vegetarian friends. This was perfect – everyone loved it.
Served this as a side to pork chops. Sort of like a creamed spinach casserole. Loved it.
MMMMMM SPINAAAAACH.
Minnah-SO-tah misses you, Amy. Glad you got to take some of it with you in the form of lifelong friendships and hot dishes.
What did Vogue’s Anna Wintour say about us? We’re built like little houses on the prairie? This casserole will make sure of it. :)
I miss ya already knowing you’re not here.
Just made a spinach casserole much like this last week — only I used some Irish Dubliner cheese, rather than the feta. Can’t beat cheesy veggie casserole, especially in the dark days of winter.
Good luck with the move chica! And at least you got to experience the midwest. For a little bit. At least long enough to get their casserole recipes. And then share them. With me. So that I never have to live there.
K thanks!
This looks delicious. Creamy, cheesy…what more can you ask for in comfort food?
