Ingredients Needed
How to Make This Cheesy Spinach Casserole
First, microwave the spinach for a couple minutes to thaw it. I do this right in the bag, its so convenient. Then drain it and squeeze the extra water out. I use a fine mesh (wire) strainer and press with the back of a spoon to squeeze as much water out as I can.
In a medium mixing bowl, beat the eggs well. Microwave the butter for about 15 seconds to melt.
Add the cottage cheese to the eggs in the bowl, then add the cubed Cheddar cheese and flour. Stir to combine.
Add the spinach and melted butter.

Transfer the mixture to a greased casserole dish.
Bake, uncovered, for 40 to 45 minutes at 350℉. The edges will be bubbly and the chunks of cheese will be melted and slightly browned on top.
Serving Suggestions
Once you try this, you'll realize how versatile it is. I've been serving it as a side with grilled chicken or pork and even with some air fried sausages. It always fits right in. I plan to double the batch for holiday meals, because this is a crowd pleaser for sure!
Substitutions and Variations
If you need to lower the carbs or be gluten free, you can just eliminate the flour. You might see a little unabsorbed liquid in the bottom of your dish when you start serving, but it doesn't affect the taste or texture of the cheesy spinach bake.
You can use fresh spinach, but you do need to cook it down first to release all the excess water. I find frozen spinach so much easier in this situation.
Frequently Asked Questions

You can substitute any gluten-free flour, if you wish. But I often skip the flour altogether for a low carb option, which also makes it gluten free.
Yes, just omit the flour. When you scoop the casserole out to serve it you might notice a little unabsorbed liquid in the bottom of the casserole dish but the taste and texture of the cheesy spinach is unaffected.

Sounds so yummy and easy! Thinking about adding cooked ziti and mushrooms or something to this to make it a meal. Do you think I would need to add extra cheese or ?to make it work?
Sula
I think you'll be fine, especially with mushrooms. I would go easy on the pasta as it might end up a little dry - pasta absorbs so much liquid! But a small amount wouldn't be too bad.
