Helpful Tips

To make this casserole you need to make cauliflower rice. I prefer making it in the food processor, but if you don’t have one you can also use a box grater. To make cauliflower rice in the food processor you can use the blade or the grater attachment.

In this recipe I want you to sauté the cauliflower rice before baking. This step is necessary to remove some of the funky cauliflower smell. It also helps to reduce the amount of water and to soften it a little bit.

Cooking the vegetables in advance takes some time but it is needed. You have to sauté the onions, garlic and the cauliflower rice for few minutes. Then cooking the zucchini.

Peeling the tomatoes is optional. I don’t like to eat peels of cooked vegetables and that is why I take this extra step.

You can either pan fry, grill or bake the sliced zucchini. I found out that baking them at 400F for 10 minutes i s way quicker than cooking them in a pan.

Remove the cauliflower rice from the stove top before you add the cream cheese and the eggs.

Depending on the size of the cauliflower you might need a different size of baking dish. I’ve prepared this recipe in square dish with 9 inch sides and in a rectangle dish (13 x 5 inches).

Also, depending on the baking dish you’ve used the serving sizes might be 4 or 6.

    Surprisingly this recipe was very fast to make which I love, and what I love even more is how delicious this casserole was. I didn’t peel my tomatoes and didn’t feel any of the tomato skin., probably why it came out faster. Definitely adding this one to my repertoire!
