When you start a keto diet, giving up some of your favorite high-carb dishes can be hard. And the warm, comforting, Italian classic lasagna might be one of them. The good news is that with a few simple tweaks in ingredients, you can easily enjoy a keto lasagna that will satisfy your comfort food cravings and not kick you out of ketosis.

Veggies make an excellent low-carb alternative to various grains. Rice can be substituted with cauliflower, spaghetti with spaghetti squash, and tortilla wraps with lettuce leaves.

Zucchini is another vegetable commonly used to replace high carbohydrate favorites, particularly pasta. With a simple spiralizer, a whole zucchini can be transformed into an entire plate of zoodles not unlike angel hair pasta.

Zucchini can also be cut into strips and layered with mozzarella cheese, ground beef, and pasta sauce to make a bubbly, meaty lasagna. You’ll follow this exact process to bake a low-carb, keto lasagna suited for the whole family.

How Do You Make Low-Carb Lasagna?

When you examine your mother’s classic Italian lasagne recipe, you’ll notice only two ingredients need to be eliminated: lasagna sheets and flour. The flour is typically used in the ricotta cheese mixture, which is easily swapped for coconut flour in this particular recipe. All other ingredients such as the meat sauce and cheeses are keto-friendly.

There are several ways of swapping regular lasagna sheets with low-carb options:

Option 1: Bake Your Own Keto Lasagna Noodles

To replace the non-keto lasagna noodles, you’ll need to find a low-carb alternative. Some keto lasagna recipes call for baked lasagna sheets made from a combination of cream cheese, parmesan cheese, and eggs. While this is a perfectly fine option, it certainly makes for a heavy dish. 

If your stomach is dairy sensitive or can’t take four different kinds of cheese packed into a single baking dish, making a keto lasagna with zucchini is a viable alternative.

Option 2: Replace Lasagna Sheets With Zucchini Noodles

Zucchini is a healthier alternative than adding more dairy to your lasagna. However, it’s a tricky process. You will need to “sweat” the zucchini noodles to prevent your lasagna from becoming too soupy.

Zucchini is packed with water, which releases when baked in the oven. Slice the zucchini then sprinkle generously with sea salt. Place your salted zucchini on a paper towel for 30 minutes. You will be shocked at how much water is extracted. Once 30 minutes are up, gently wring the zucchini noodles with a paper towel one last time to extract any moisture.

Using eggplant instead of zucchini is also an option, but be aware that eggplant is a nightshade vegetable, along with tomatoes and potatoes. Studies have shown that people who suffer from chronic inflammation or auto-immune diseases might adversely react when eating nightshades. If that is the case, stick to zucchini and you’ll be just fine[*].

What Makes Zucchini So Healthy? 

Zucchini is a common ingredient in keto recipes, most commonly in Italian cooking. Zucchini is naturally gluten-free, contains a low net carb count, and is extremely low in calories. That’s why it’s a great way to transform an otherwise gluttonous comfort food into a healthy, low-carb recipe.

If you check out the nutrition facts below, zucchini is the reason why this recipe stays within 12 grams of carbs per serving. Traditional lasagna, on the other hand, could contain up to 35 grams of carbs per slice[*].

Zucchini comes with roughly 5 net grams of carbohydrates, zero fat, and around 3 grams of protein per cup. It’s packed with a number of vitamins and minerals, including vitamins A, B, C, and potassium[*]. 

These vitamins are vital in a number of roles such as maintaining the integrity of tissues and promoting cellular and vascular health. Research has shown that potassium deficiency may increase the risk of stroke and coronary heart disease[*][*][*][*].

Finally, using zucchini in lieu of high-carb pasta is a great way to “hide” vegetables. If you have a tough time convincing your partner or your kids to eat enough vegetables, this is a great way to sneak in an extra serving. 

This particular recipe uses four entire zucchinis in a single lasagna. Since this recipe yields six servings, you will consume two-thirds of zucchini in one meal.

You’ll also be pairing these nutritious veggies with some great saturated fats like lard or ghee, which will help your body to absorb the benefits of zucchini in the most efficient way possible[*].

Kitchen Tools You’ll Need

Believe it or not, this keto lasagna is a fairly easy recipe that doesn’t require any fancy kitchen tools. Below is a list of the basic equipment you’ll need.

  • A casserole dish (the deeper the better — don’t use a baking sheet or a sheet pan, as the tomato sauce and ricotta mixture will splatter everywhere).
  • A skillet 
  • Foil
  • Two large bowls, one to mix your cheese mixture and one to mix your Italian seasoning.

For the ingredients, see below. All the ingredients should be easily found at your local grocery store.

Recipe Notes

For the marinara sauce, Perfect Keto typically uses Rao’s. However, you can use any brand you wish, as long as it doesn’t contain added sugar (be sure to double-check the ingredients label).

Now that you have a delicious and easy low-carb lasagna to add to your keto meal plan, be sure to check more ketogenic versions of your favorite recipes. Here are a few ideas that will make great low-carb dinner options.

  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?

    1. 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.

  6. 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!!!!
