Ermahgerd-worthy Low Carb Instant Pot Keto Lasagna

By Bree

Keto lasagna has quickly turned into one of my weaknesses. Once it’s in front of me, I’m a goner! There’s something about the smell of it baking in the oven that just puts an instant smile on my face. If you love lasagna, or you’re looking for a low-carb meal that your family is sure to love, read on. This is going to be a treat.

Zucchini, A Keto Dieter’s Best Friend

While zucchini wasn’t my favorite vegetable growing up, I often encountered it in my mom’s cooking so I’ve become quite familiar with the different varieties of it. Now that I’m a mom myself, I find it easy to incorporate into a lot of my family’s meals because it’s mild in flavor and cooks pretty quickly.

In fact, I have a list of recipes that I like to make every once in a while when I’m looking for something quick and easy:

Of course, when it’s smothered in cheese and sauce, it’s hard not to love it. That’s exactly why this keto lasagna is such a hit. Zucchini as a pasta alternative is genius because it’s low in carbs, but high in volume. So if you’re looking for something to add bulk to your meal, it’s an excellent option.

Making this keto lasagna is fairly simple, too. You only need a little over half an hour to prepare and bake this recipe. It starts off with slicing the zucchini into relatively thick slices. to season the zucchini, sprinkle some salt over it and then pat dry with paper towels. You’ll then place the zucchini slices in between some pans to help absorb the moisture even more.

Once that’s soaking dry, you can prepare the other ingredients. In a separate bowl, combine your cheese, seasonings and eggs and set that aside. For the next part, you’re going to need your Instant Pot.

I love my Instant Pot for overnight cooking, but I also love it for quick bursts of pressure cooking. For this recipe, we’ll be using it to quickly make the meat sauce. For the meat sauce, you’ll be using ground beef, tomato sauce and of course, some seasonings. Make sure to taste your meat sauce at this stage because it will be more difficult to season your dish once you start layering it with the zucchini.

Once the meat sauce is done cooking, set it aside in a separate bowl and wash the Instant Pot insert. You’ll be using it to layer the lasagna. Start with a layer of meat sauce, some zucchini slices, some ricotta, and then finally some mozzarella. Keep repeating this until you’ve used up all the ingredients.

Seal your Instant Pot and leave it to pressure cook for 10-15 minutes. This will give your lasagna enough time to become gooey and melty–just the way it should be!

The Zucchini Layers Ended Up Too Mushy/Too Firm

For most Instant Pots, the standard 10-15 minutes on the pressure cook setting should be enough, however, don’t be afraid to play around with it. There is a limitation to the pressure cook setting in that it’s sealed shut, so you can’t keep raising the lid to check on the doneness of your zucchini.

One way you can monitor the doneness of the zucchini is to observe if the zucchini has gone translucent (mushy) or if it’s still fairly opaque (firm).

My Keto Lasagna Ended Up Being Too Watery

Zucchini has a high water content, so if you neglected to pat your zucchini slices dry after slicing, this could have contributed to a watery lasagna. Also, another reason why could be that you used chilled or frozen zucchini instead of room temperature zucchini.

Is There An Alternative to the Zucchini Sheets?

If you’re just not into using zucchini as a pasta alternative, not to worry because there’s actually another option you can use for this recipe. QueenKeto has a recipe for making lasagna sheets that have a similar texture to real pasta but without the excess carbs. Give it a try and let us know what you think of this version of keto pasta.

If you’d still like to keep it vegetable-based, I recommend trying spaghetti squash and slicing it a little thinner than ⅙ of an inch. You would have to use thinner slices of spaghetti squash because it’s firmer than zucchini, so it would require longer cooking time. However, spaghetti squash contains more carbs than zucchini, so in order to have this and still fit the keto guidelines, you would have to limit your servings.
