There is nothing better for this time of year than the aroma of freshly baked apple pie. As you may have guessed, this one has no apples in it.

I have to admit that I was really hesitant to use zucchini in a sweet pie. I got inspired by this Zucchini Apple Fritter Bread from Lisa of Low-Carb Yum. It's so good you will never know it's not apples!

Apart from zucchini, I used my Keto Caramel Sauce and Sweet Keto Pie Crust to make this recipe.

This pie was a great success. In fact, I managed to fool everyone with my zucchini pie! I didn't tell my fiancé what it's made with and his instant reaction was: "...but I thought that apples are not low-carb?" He loved it and asked for another slice.

A day after I had a friend visiting with her husband. They don't know much about low-carb, paleo or keto so they had no idea that this was not just another apple pie served with some "regular" vanilla ice-cream. You should have seen their faces when I told them that there were no apples, flour or sugar in it. Her husband is a diabetic so he was really pleased that he could have a slice without spiking his blood sugar.

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

Hi, I was wondering if you have tried preparing the filling and freezing it for later use. Thank you.

I have not but I assume it will work just fine. We have a recipe for "apple" butter that is freezable and we will share it in the next few weeks 😊

I think this recipe was awesome, it just needed to be a little bit sweeter. Next time I will add some stevia or monkfruit to the filling. But i was amazed at how similar the zucchini fits into place of apples, they even absorbed the lemon juice for a tartness, still so good! Thanks again!

Thank you for your lovely feedback! The good thing about low-carb sweeteners is that you can add more or use less to taste without affecting the texture 😊

Oh wauw its really apple pie look a like. I made it Friday, gave a piece to my son yesterday without telling him that it was zucchini in stead of apple. He hasn't noticed it at all. I myself was very sceptical because of the zucchini but it's just for the structure not for the taste. I ❤ it

I'm glad you enjoyed! 😊

Reply

You can use it if you can find it PG-free 😊

I noticed somebody wanted to use apple extract. What is PG free?

Reply

Hi Evelyn, PG refers to propylene glycol.

I made the pie crust with every intention on making this for Thanksgiving. Well as life happens, I couldn't make it. I put the crust in the freezer and just got to it. The crust held up great and the pie was unbelievable. One of the things I miss most is apple pie and this hit the spot. I made the other caramel sauce you linked to, and it came together and was so good. I can't wait to make it for Christmas.  I will be sure to tell everyone what is in it, hopefully this can convert them. If not, this pie heats up great, a little whipped cream and I'm good getting thru the table of cookies and other pies and cakes.
Thank You!!!!!

Many years ago my sister made a pie similar to this and she told her family it was squash,  They wouldn't even try it.  She gave me the recipe and one week  that summer her son came to visit, I had raised a very big garden with zucchini. I made the pie and it went over very well, that week I made 9 of the pies and they were all gone in a wink of the eye.  Even the nephew ate them.  Haven't made any in a long time.  I think I will get a squash and make one.

I was surprised myself - it was the first time I tried zucchini in a sweet recipe and couldn't believe how similar it is to apples 😊

YOU ARE USING YELLOW SQUASH.  DO YOU CALL THOSE ZUCCHINI?  ZUCCHINI IS GREEN IN THE U.S.

Reply

You can use both - the nutrition facts are the same in both types 😊

Dear Martina,
What can I use instead of cream of tartar? It's nowhere to be found here in France

Reply

Hi Greg, you can use a tablespoon more of lemon juice 😊

The Title is "Low-Cab" shouldn't it be "Low Carb"?

Reply

Thanks for spotting that! Fixed! 😊

Love the caramel sauce and the pie crust, used it several times to make coconut cream pie and even a savoury pie. This is definitely a Thanksgiving keeper!!!
