  1. Where does the garlic powder and clove of garlic come into play? Do you mix it in with the cheese mixture? Didn’t see garlic among mixture instructions.

  2. This sounds really good and I hope it turns out OK (currently in the oven). I do think the instructions in the recipe are confusing. You don’t account for time/direction on slicing the zucchini. Additionally, you’re forgetting the garlic powder and chopped garlic, what step does that come into play? Now my lasagna is sans garlic! Hope it comes out ok.

  3. What purpose does the coconut flour serve? Is it absolutely necessary? I hate coconuts. Thank you for the wonderful idea of using zucchini!

  4. Information is very helpful and helps me in making it. Now I also made just like the real thing low carb keto lasagna. Thank you

  5. Hello, I have this recipe in my oven right now. I am really excited to try it. I noticed the directions did not say when to include the garlic or garlic powder (I just added it to the sauce). What’s more important though, I am not sure how many servings this is making. Can you please update this recipe with the right information so we can keep a proper count of our carbs?

  6. Hi Dana, thanks for pointing that out! We’ve fixed it on our end. This recipe yields 6 servings cooked with 12g of carbs each serving.

  7. Hi Jen, I’m sorry about that. We’ve fixed it for you. It should be added with the ricotta mixture. Thanks!

  8. I used 85 percent beef instead and mozzarella, parmesan, and swiss cheeses instead in an attempt to lower the carbs. And I used zucchini noodles, just for ease because they were pre-packaged. This is probably the best thing I’ve ever made! It was mouth-watering good! THANK YOU!!!!
