Spinach squares are a tasty keto appetizer bursting with bold flavor. Packed full of spinach and Cheddar, they’re easy to make ahead for any get together. Less than 3g net carbs per serving!
I love when a recipe takes me by surprise and turns out better than I dared to hope. And these cheesy spinach squares really did surprise me with their deliciousness.
It’s not that I thought they wouldn’t be good. Just a quick peek at the ingredients indicates that they will be tasty. But I liked them so much, I found myself looking forward to them as a post workout snack every day.
And I was sad when they were all gone. So I immediately whipped up another batch, which was just as good as the first. No surprise there!

Retro appetizer recipe
Have you ever heard of spinach squares? I hadn’t until recently but they seem to be one of those retro recipes that’s making a comeback.
You know what I mean, one of those recipes that comes from some 1950s women’s magazines. The sort of thing one might serve to the husband’s boss when he comes to dinner.
As with many older recipes, they don’t look all that impressive. But then you taste one and you realize that looks aren’t everything. Because oh my, do they ever taste good! More, more, give me more!
The original spinach squares take flour, but I used coconut flour to make them keto-friendly. I had to add more eggs, and then I tossed in some cooked bacon too. Because bacon makes everything better!
Ingredients
- Frozen spinach
- Coconut flour
- Baking powder
- Salt and pepper
- Cheddar cheese
- Eggs
- Butter
- Whipping cream
- Garlic
- Bacon (optional)
How to make cheesy spinach squares
This keto appetizer recipe is so easy and so flavorful, you’ll want to make again and again! Here are my best tips for getting it right:
- Thaw and squeeze the spinach: Frozen spinach can add a lot of excess moisture and make the spinach squares soggy. Make sure you really squeeze it out properly.
- Grate the cheese: I really like the flavor of sharp white cheddar in these squares, but you can use milder cheese if you prefer.
- Whisk the dry ingredients: A little coconut flour helps bind the spinach squares, and a touch of baking powder helps them rise just a bit. You want them to be fairly dense.
- Stir in the wet ingredients: The batter should be thick but still spreadable.
- Add bacon: It’s optional but it makes the squares that much more visually appealing.
- Bake until firm: The edges should be golden brown and the top shouldn’t feel wet at all.
- Let cool completely: The bars will be much easier to cut when cool.
- Serve warm or room temperature: They are meant to be finger food so you don’t need a fork!
Frequently Asked Questions
Yes but you will need to use a full cup of it. And then you need to reduce the eggs to two (possibly three if the batter is dry). Without having tried it myself, I can’t be sure of the baking time so keep your eye on it.
Sure! You do need a cheese that grates properly for the right consistency, but any semi-hard cheese should do.
You can make keto spinach squares several days in advance and store them in a covered container in the fridge. They should also be good in the freezer for up to a month. Wrap them tightly to avoid freezer burn.
No, it’s completely optional. Tasty, though!

The first time I made this recipe, I didn’t have all the ingredients so I made a couple of substitutions. I didn’t have spinach and not very much bacon or cheddar. But I did have a can of artichoke hearts to replace the spinach. And I added some breakfast sausage to the bacon. Then combined the cheddar cheese with an italian blend. It was amazing! I have made it this way several times, and even take it to church potlucks.
These were delicious! I made them as a side to veggie soup today to test the recipe. They will make great appetizers or even on the dinner table at thanksgiving!
Can you use fresh spinach??
Thanks
You need to sauté it and cook it down first, and then drain it.
Would almond milk work instead of heavy cream?
It’s much thinner so I am not sure that these would set as well.
I love all your recipes. Could I sub in oat hull fiber for the coconut flour in this?
These spinach squares were a delightful surprise! I love a recipe that combines good flavor and nutrition. Thanks for sharing!
These spinach squares are DELISH. Love having healthier snacks on hand!
This is a crowd pleaser! Absolutely delicious and so perfect to take to a ladies’ potluck brunch!! I like to use Cabot extra sharp white cheddar in mine. Absolutely my favorite cheese. The directions are simple & the recipe is easy! Love this!
I would love to make this into more of a casserole for dinner…a keto spinach casserole if you will.
How would I do that?
Thank you so much!
I just love ALL your recipes!!
Made the carrot cake with cream cheese frosting and my family did not know the difference!
I’m not sure, I guess you will have to experiment!
I made these for breakfast this morning. Actually they were slightly over baked because the electricity went out in the middle of baking and I overcompensated. Even so, they were delicious. Highly recommend.
Simply I just love your recipes. I am diabetic and looking for low carb food that has flavor. Thank so much for sharing.

These sound yummy!!!
I don’t like coconut flour or almond flour. Could I use rice or tapioca flour instead?
Not if you want to be low carb!
I’m diabetic, and use a lot of alternative ingredients. My go-to flour substitute is Lupina, a lupin bean flour. (Some brands ate bitter, Lupina is not) It’s 4 net carbs per cup. It tastes great, and I think it would work in this recipe. Another great alternative is soy flour. Not as low as Lupina, but still very low.
You won’t even taste the coconut flour in here,it makes the dish the right consistency! If you have some just try it!
Ok to substitute fresh spinach?
If so, any idea of quantity?
You would want to cook it down some first and then try to drain any excess moisture. I would also chop it up so the squares are easier to cut. And I’d use about 12 ounces, possibly more since it will lose weight as you cook it down.
Carolyn I have a large container of fresh organic spinach could I replace the frozen spinach with it?
Thank you

Looks like a great reheat breakfast too! I love your recipes, instructional videos & tips. Please keep creating!! Your work is invaluable to the keto community.
They really are good for that too. I ate them as a post workout snack with some sausage!
Can these be cooked using a mini muffin pan instead of 8×8?
You will have to experiment! 🙂
They turned out great! About like a mini quiche. Serving them at my nieces bridal shower. 20 minutes at 350 was perfect.
Thanks for the suggestion of muffins instead of squares. Making them tomorrow!
Thank you for sharing.. I was thinking the same thing…
