I love spicy food and this seasoning is my favourite. For those who are calorie-conscious, zucchini chips are not only low in carbs but also calories. They contain about 50 calories per serving and are a good source of heart-healthy potassium!

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.

Can I use lemon instead of lime?

Absolutely! Any flavour you like 😊

These are Fantastic !! I just made a batch and I love the flavor and crispness. ThAnk you for the recipe. 😀

Thank you Donna!

At what point do you put the spices on, before it goes in the oven?

Yes, it's before you place them in the oven - just added some info in the steps 😊

Can't wait to try these. Just starting cleaner eating with the whole fam and trying to find recipes the kids will enjoy...they're pretty scared of eating better and what that means, but so far no big complaints!

Thank you Elaine, I'm glad to hear that! Let me know when you try them 😊

Never mind, just saw it.

That's ok. If you are wondering how I got the values, I usually use the USDA database.

Hey! Thanks for this awesome recipe, just one question though. Do you know how many calories are in this serving?

Sure - the nutrition facts are at the top of the post (54.4 kcal per serving) 😊

Looks damn good - can they be saved or do they have to be eaten right away???

Thank you! They don't usually last for long when I make them 😊 I guess you can if you make them really crispy - best in dehydrator or oven on very low temperature and then keep in air-tight container so they don't get soft.

The best low-carb crisps I found! Honestly, I love the spicy seasoning. Thank you so much!
