Baked Cheddar Spinach Squares
Today’s menu item is similar to quiche and may be used as a bite-size appetizer or cut into bigger squares for a veggie option on your dinner plate. A convenient recipe for entertaining or a busy weeknight, what is essentially a cheesy baked spinach may be cooked ahead and reheated and freezes well, too.
Those who visit my website or read my newspaper column regularly know I love to provide options, and this recipe is no different! As an alternative to the spinach, you may substitute a 10-ounce box of frozen, chopped broccoli. Either way, simply follow the moisture-removing tip to ensure a perfect outcome.
This recipe may be made ahead and reheated, is an excellent hors d’oeuvre or side dish, and freezes well.
- 1 10-ounce package frozen spinach, thawed
- 1 cup flour
- 1 teaspoon baking soda
- 1/2 teaspoon kosher salt
- 1 cup milk (non-fat is fine to use)
- 2 eggs
- 1/2 cup onion, finely chopped
- 3/4 pound (3 cups) shredded sharp cheddar cheese, divided (see note)
- Preheat the oven to 350 degrees.
- Remove the moisture from the spinach. To do this easily and thoroughly, my favorite trick is to wrap a clean tea towel around it and, literally, wring it out. (If you have never done this, you will be amazed at how much water is in there!) Then, separate the spinach with two forks or with your fingers.
- In a large bowl, mix the flour, baking soda, salt, milk and eggs with a fork. Stir in the onion, two cups of the cheese, and the spinach.
- Spread the mixture evenly in a greased, 12×8 baking dish. (Two 9×5 loaf pans have a similar surface area and you could eat one now and freeze one for later.) Sprinkle with the remaining one cup of cheese, and bake for 30 to 35 minutes or until cooked through and golden brown on top. (Sometimes, I move the dish to the top rack for the final two minutes or so to brown the top a little more. Just watch closely if you do this, so as not to burn.)
Notes
When serving as a side dish, I have occasionally made this with one cup less cheese, and it is also delicious. If you prefer a lighter option, simply add one cup of cheese initially, then top with one final cup before baking.

The Fountain Avenue Kitchen was my grandmother’s kitchen, the kitchen where I first pulled up a stool and watched the magic of turning basic, fresh ingredients into culinary wonders. Through today’s Fountain Avenue Kitchen, I hope to inspire people to try a new recipe, learn a new technique and eat more vegetables and wholesome grains ... but still enjoy a little dessert now and then.

I love giving my readers options too, so much more fun for them:-) Your baked cheddar spinach squares sound delicious, and would be great for a traveling girl! Hugs, Terra
Thanks, Terra! And you are right…these are the perfect recipe to make ahead and reheat or freeze in individual serving portions, and they stay fresh for quite a number of days in the fridge. Hope you are well, my dear!
Would fresh spinich work as well? we always have fresh spinich and brocoli on hand as we buy at Sam’s club. hmmm I bet this dish would be perfect for left over brocoli also!
This recipe is going to be used a lot! Thank you!
I hope you love it, Linda! And, yes, fresh spinach or broccoli will work, too. Just make sure to cook it first and remove all the moisture. That is the key to great texture and taste. I love having leftover broccoli, too. So many great ways to reuse it!
Love this recipe tried it today, keep up the great job, I did not cook the fresh spinach first,but my children love it any way, will try cooking it another time and let you know, but was great . Looking forward for more new things try
One of my good friends and cooking buddies just made this recipe for a recent get together after seeing it in the Sunday paper- it was excellent. I will have to make this soon since our entire family loved it so much! Great way to get the kids to eat more veggies!
Thank you very much for the thoughtful comment, Sarah! I am thrilled your whole family enjoyed them and so appreciate the feedback!
