Keto Zucchini Lasagna Recipe

I have always loved Italian foods with lasagna being towards the top of my list. Of course, lasagna noodles aren’t low carb. Thankfully, there are many pasta alternatives that satisfy my cravings for my favorite Italian recipes without the added carbs like in this Zucchini Lasagna recipe,

One of the biggest reasons that I love this recipe is that it’s super simple. Isn’t that one of the biggest hassles of actually making lasagna? It seems to take a long time and is quite a labor-intensive recipe! Luckily, this recipe requires little time and effort on your part!

What can I use instead of pasta in lasagna?

There are many different versions of low carb lasagna recipes; my favorite pasta substitute is zucchini. When chopped into small pieces and sauteed, it gives just enough texture to the dish to fool your tastebuds.

Below, I have included a step-by-step pictorial along with tips for making this recipe and substitutions. Make sure to scroll to the bottom of the post for the recipe card with the full ingredient list and instructions.

 

browning ground beef for low carb zucchini lasagna

Start by browning the ground beef in a skillet with chopped onion and minced garlic.

*If you happen to keep ground beef already browned in the freezer like me, it will save you quite a bit of time. Doing so is one of the few meal prep steps that make my week easier explained in these five easy steps to meal prep.

Tip: If you prefer, you can sub turkey for ground beef.

What low carb marinara sauce should I use?

If you aren’t familiar with what low carb marinara sauce to use, I’ve listed several below for your convenience. I have found all of these sauces at my local grocery store.

saute chopped zucchini in butter in a skillet

Make sure to slice the zucchini in bite-size pieces for this zucchini lasagna. While I typically sautee zucchini in butter, olive oil would work fine. After you have sauteed the zucchini for just a few minutes, set it aside on paper towels so as to absorb the excess moisture.

While some people cut zucchini very thin vertically to mimic lasagna noodles, I find this method of bite-sized pieces much easier and quicker. With four kids and a full life, we just have to make it work sometimes, and easy is the name of the game. If you’d like to try your hand at slicing zucchini, follow the slices instructions here.

How to get the water out of zucchini lasagna?

Zucchini has a high water content, and I don’t like for my lasagna to be watery, so these steps are key to making this low carb lasagna recipe amazing.

  1. Before sauteing the zucchini, salt it just a bit and let it sit for approx 10 minutes. The salt helps draw out moisture to avoid a watery lasagna.
  2. After you saute, the zucchini set it aside on paper towels before layering in the casserole dish.

Now that the tomato sauce and zucchini are ready, it’s time to layer the ingredients in a 9 X 13 baking dish. You’ll need two layers for the lasagna to set up properly starting with the spaghetti sauce and ending with a final layer of mozzarella.

adding ricotta mixture layer to zucchini lasagna keto recipe

After the zucchini layer, the ricotta cheese mixture is the next step. To make it easier to spread, I spooned it out in rows as pictured above then used the back of the spoon to spread it out.

Should I cover Lasagna with foil while baking?

To prevent lasagna from drying out, it is best to bake it for at least part of the baking time covered with aluminum foil. Remove the foil at least halfway through the baking time so that the top can brown.

How long should lasagna sit before serving?

It’s not going to be easy to wait, but you should let the lasagna rest approx 15 before cutting to let it set up. Otherwise, the layers will fall apart into a mess

Incredible Italian flavors, a delicious meat sauce, and a zucchini and ricotta cheese layer topped with melted mozzarella make this easy keto recipe a hit. I’ve even had several people comment that they enjoy it more than traditional recipes with real noodles, which blew me away.

Is Keto Lasagna gluten-free?

This recipe should be gluten-free without the noodles. However, I always suggest checking the labels of all the ingredients you use in your kitchen as there could be added gluten that I am not aware of in the ingredients.

How many carbs in low carb lasagna?

With the ingredients I used in my kitchen, this recipe came out to only 5g net carbs per servings, which is impressive. It will definitely be on regular rotation in our home.

    I’ve made this recipe so many times. It is amazing. My hubby and I prefer it over the traditional noodle lasagna. I would like to make this ahead and freeze it for when I have house guest. Do I bake first then freeze? Or can I put it straight in the freezer after preparing the dish?

    1. You can assemble the casserole and freeze it. Then thaw and bake. It will likely take a bit longer to bake since it will be cold.

  2. I would probably use a Mandolin and slice it thin and use the Zucchini like Lasagne noodles and layer it. Its really hard to find Spaghetti sauce low in carbs but I will keep looking.. from Ontario Canada. I love all your recipes, so inspiring, and so yummy thanks for sharing.

    1. That would def be an option. I just don’t have the time and patience. lol
      So glad you enjoy my recipes! I appreciate your kind words.

    1. With 4 kids, I need easy and that would take too much time for me to cut it that thin. I prefer the ease of cubes personally, but it’s worth ta try.

  3. 5 stars
    SO GOOD!!! I’ve made this 100 times and it seems to taste better every time! I’ve given the recipe to lots of people and they rave about it….my family and extended family love it! Make sure you use Marinara sauce though…it really makes it taste so much better than even an expensive pasta sauce! So quick and easy and VERY filling and VERY tasty!

    1. I’m so glad you all love it! Thanks so much for taking the time to comment. I appreciate it so much and value your opinion.

  4. Chopping up the zucchini was brilliant!! Harder for my 19 year old to taste……so definitely a win!! The taste was great too!! Definitely will be added to the regular menu, thank you!!
