How to make low calorie lasagna

Traditional lasagna can exceed 350 calories per slice. Some recipes are much higher than that. This one however came down to only 98 calories per the same size of a slice of lasagna. Not only that, the protein stayed high (15 grams) and the fat was low (only 1.4 grams.. FOR LASAGNA!)

Definitely a small miracle.

Using Zucchini instead of pasta for low calorie lasagna

The first swap was replacing the lasagna pasta noodle with zucchini. The zucchini can serve as the pasta layers, while bringing down all of our macros. Cup for cup you

Using fat free cheeses instead of full fat

I understand fat is not a bad thing. I understand we need fat in our diet. HOWEVER, I’d rather get my fat from other clean sources like avocados and coconuts, rather than cheese.

In addition, getting fat free cheeses drops the calories! So, for me, this is a win win! I found fat free mozzarella at Walmart, and fat free cottage cheese is everywhere. This saved a huge amount of calories and fat.

Using 50 calorie spaghetti sauce (Classico)

I turned over every jar of pasta sauce at the store, and found the Classico had 50 calories per half cup. The others had about 60 or 70, with some even more. For 3 servings, that potentially could have added 60 more calories.

Using 99% Lean Ground turkey

And the final savings came from using 99% lean ground turkey. I found this at Walmart. 85% lean ground turkey has 170 calories (per 4 ounces), whie the 99% lean only has 100 calories. Plus, you save 7 grams of fat for every four ounces.

So, that leads me to the final recipe! Go out and track down some fat free cheese and zucchini, and you can have this low calorie lasagna on your table in no time!

  1. I use a jar of no sugar added pasta sauce and add a can of diced tomatoes to it for pasta. I am anxious to try your recipe for lasagna and I am waiting for a spiralizer for my zucchini “pasta” dish. I haven’t had any pasta for the past two months and I really miss it! Thanks for sharing your tips and recipes.

  2. I’m happy to have found your recipe and plan to try it next week. Does the fat free mozzarella really melt like in a traditional lasagna? I would like to avoid crispy shreds if unmelted cheese. Thanks!

  3. 5 stars
    This was absolutely delicious! I almost felt guilty because it tasted like traditional lasagna, I even had to remind myself that this was okay to eat on my low-carb diet. Amazing! Thanks for sharing this recipe, can’t wait to try more!

  4. I have found that salting the zucchini as it rests, and then patting it dry helps with the soupiness.
