Zucchini Lasagna Soup with Lentils

Last week’s weather was brutal – the Monday night storm (which I missed, because I was traveling) and the lingering frigid temperatures that lasted through the week.

All I craved was soup! I had lentil soup as a late afternoon “snack” on Thursday and Friday, trying to thaw out.

Since we’re ALMOST in the 50s temperature, I figured I’d share a healthy, warming soup to get us there.

Zucchini Lasagna Soup with Lentils

If you’ve ever had lasagna soup, you know how comforting and filling it is. The lasagna noodles fill up the soup and soak up the flavors of the soup.

This zucchini noodle version replaces the lasagna noodle with, well, zucchini noodles.

We use Blade A for this soup to create ribbon-style noodles with resemble the consistency of true lasagna noodles. It works so well, you won’t miss the lasagna!

Zucchini Lasagna Soup with Lentils

For this version, I chose to make it vegetarian-friendly, so I used lentils, but if you want to make a true lasagna-style soup, you could stir in some ricotta, you could use ground beef or sausage – just customize it to your favorite lasagna.

Consider it a deconstructed lasagna in a soup.

Happy Sunday, everyone! If you’re meal planning, add this one to the list!

  • Your Pin It buttons have not been working for about a week now!!! Please fix it, thanks.
  • Hi Ali, first of all I love love love the inspiralizer and how many yummy recipies you can do with it! It is so much fun and my toddler is eating more veggies thinking they are spaghetti hehe...My only difficulty is that I am not familiar with cups as measurements for the ingredients, are grams included too in your books or only Cups? Would you kindly specify on the website or somewhere the exact converted measurements to the cups you usually use in your recipies? I'd be most grateful, thanks for all the Inspiralization! Always looking forward to your posts x
    • Are you in the UK? If you are, there's a UK edition of my cookbook where things are in grams and those measurements!
      • Thanks ever so much for your time and your kind reply Ali, I'm so happy! Yes, I'm in the UK :-), I will definitely check it out!! Thanks a million again x
  • What?????? "If you’ve never had lasagna soup, you know how comforting and filling it is. "
  • this looks lovely, Ali - and would taste even better next day im sure - a great work lunch option!!!
  • This dish is absolutely delicious! Great recipe.
  • When/where does the water get incorporated?
    • With the vegetable stock, the recipe has been updated!
  • Made this for dinner tonight. Subbed fennel bulb for onion and used half of the tomatoes called for. No cheese but no problem- this turned out great!
  • I'll make this over the weekend, and freeze some for lunches in the coming week or two -- it looks delicious. Hope it freezes well (don't want mushy "lasagna" noodles!) Ali, I jumped right on that Amazon Flash Sale a couple of weeks ago and got "Inspiralize Everything" -- so now I have both cookbooks! Yay!
  • I made this for dinner and it's great! In addition to all the ingredients listed, I added fresh oregano, spicy Italian chicken sausage and some Frontier Pizza Seasoning.
  • Hi! I just upgraded my spiralizer to your inspiralizer and am super excited as it worked so much smoother and clean-up was so much better. AND this soup is currently cooking on my stove :-) I have a question about the WW smart points; I was wondering how you got to 7sp per serving? According to my calculations it is 3SP per serving unless you were counting the mozzarella? I assumed since it said optional and no amount was listed you didn't... The only 3 items with points (since veggies are free) that I can find are the lentils (16sp/cup), olive oil (4sp/Tbsp) & stock (3sp/5cups) and those total 23SP. Divided by 7 that equals 3SP...
    • I just noticed it doesn't say optional and DOES list a measurement for the mozzarella OOPS ;-) but with that it still only comes out to 4SP in my calculations...
