Primal Pizza Pie Layer Casserole, primal and low carb with paleo option.

Primal Pizza Pie Layer Casserole is a grain free, low carb, and family friendly casserole. We love this pizza casserole at my house. Even the kids love it. The veggies are hidden, and you really can’t taste them.  My daughter did notice the green specks of zucchini in the crust, but thought it was herbs. If you leave out the cheese, then this casserole becomes paleo friendly too. Makes great leftovers too, and can be made in advance and reheated. Finally, something grain free and low carb that I could bring to a potluck. When making this, I was going to drain the meat completely, but was too lazy to transfer from the pan, so I just poured a little off into a metal bowl.  I was also going to strain and squeeze the ground zucchini, but also felt that was too many steps so, I just dumped it in as is. I put a little more coconut flour then I had originally planned on to absorb the zucchini moisture. Yay, it worked, I get to skip another step.  What is your favorite kitchen short cut?

    Hi. Just found your site and this recipe, sounds delish! Your serving size seems way to small for our family. A 9″ pie dish would serve 1 maybe 2 of my teens. =) Would you recommend doubling the whole recipe if I want to make this in a 9X13 dish? Can’t wait to try it and I love that you suggested using the veggie crust layer as single pizza crusts in the comments above. Will the crust get crispy if use it that way? Thanks for the recipe.

      Lilia, I make this in a 9x11x3 inch oval casserole dish, not a 9 inch pie dish. So it is a much deeper dish than a 9 inch pie dish. I think a 9×13 inch would work as well without doubling, but you could double it and make two 9×13 or 2 of the 9×11 casserole dishes. The crust on this one one is more bread like, not a crispy crust, but it may work for pizza crust if rolled out thin between parchment papers. Lol, I know what you mean about teenagers. I have 2 college students and a 12 year old boy. Not to mention, my hubby, who eats like a bear getting ready to hibernate and does not gain weight (so not fair).

  2. Teresa says

    Made this today and it was fab but I made too much of the cauliflower crust. Any suggestions what I can do with the left over grated cauliflower and zucchini mixture? I have already mixed it with the eggs, butter etc.

    • says

      Hi Teresa, thank you, I’m glad you like it. The leftover crust makes an excellent crust on a quiche, also is good fried as patties in oil as a fritter. Can also be pressed between two sheets of parchment paper to make a regular pizza crust.

  3. Caz says

    Hi, could you explain the serving size as I don’t understand the size of 1 square. How many serves does this recipe contain.

    • says

      Caz, it is 1 serving out of 5 total servings. The info is at the top of the recipe card, but the print is so small. I will put it in the nutritional data as well to make it easier to see.

      Hi Melinda, I have made this in advance, and left in the fridge until ready to bake. I have not tried freezing it yet, but I would think you could and would just need to bake for a longer amount of time.

  4. amber says

    This looks great and I’m trying to do more l do more low carb foods. Do you think I could use frozen cauliflower after it’s thawed? Or would it be too mushy.?
    Thank you

    I am making this tonight and can’t wait! One change I will make is to bake it in the same cast iron skillet I brown the meat in…one less dish to clean ;)


  1. […] 60. Primal Pizza Pie Layered Casserole When it comes to pizza on Paleo, you have a few different options. You can use one of these Paleo friendly pizza recipes, or you can make something like this pizza pie casserole. It has all the flavors that you want from a pizza, but without the crust that usually gets a Paleo eater into trouble. The bottom layer is made up entirely of ground beef, and then they put a vegetable crust over the top of the meat layer, making it a balanced Paleo meal by giving you your vegetables. The cheese on the top is optional, so use your best judgment on this and opt out of it if you know you can’t handle cheese. […]
