Are you looking for the ultimate low-carb vegetarian lasagna recipe? Well, we have your new favorite recipe! Our deconstructed lasagna recipe has plenty of vegetables (as any good vegetarian lasagna should).

The best part of this lazy, low-carb veggie lasagna is that it takes just minutes to prepare but has all the same amazing flavors as your favorite regular lasagna recipe. For meat lovers, we also have a classic version of this fantastic dish in a low-carb recipe you'll love!


One little-discussed conundrum that vegetarians face is how to balance a low-carb diet with a vegetarian lifestyle. Following a low-carb diet, especially a keto diet, can be particularly challenging. After all, how do you stay full if you cut out both meat and carbs?

Fortunately, many vegetarian and even vegan protein options can help you stay full and satisfied without loading up on carbohydrates. Options like nuts, tofu, chickpeas, beans, and chia seeds provide a protein boost.

If you’re cutting back or cutting out meat, you can rely on eggs and dairy products as healthy protein sources. Now, not all people looking for vegetarian lasagna options are vegetarian, either. Maybe you just want to add a few veggie-forward dishes to your routine. Pescatarians and those who keep kosher may like to have some vegetarian options for meals when they aren’t having meat or fish.

No matter your lifestyle, a vegetarian lasagna recipe can be satisfying for all—even the most carnivorous meat lover. Mushrooms make this vegetarian lasagna taste meaty and savory without the usual beef. The secret is a flavor called umami. It's that meaty, satisfying taste you get from mushroom dishes, miso broth, and soy sauce.

This deconstructed vegetarian pasta dish is ultra satisfying thanks to spinach, zucchini, onion, and garlic. There are so many amazing flavors here that you definitely won’t miss the meat.

Oh, and did we talk cheese? One of the best parts of lasagna is the cheese, and this recipe BRINGS IT. We have creamy ricotta, stretchy mozzarella, and tangy parm. There's no deprivation or "womp-womp” sadness when you have this deconstructed vegetarian lasagna! It’s all stress-free deliciousness! This vegetarian keto lasagna recipe is a great option for a meal that doesn't feel like deprivation.


If you're cutting out carbs, the best path to success is one that involves yummy foods. Look for healthy ways to meet your cravings so you don't cave to temptation. Telling yourself that you can never have pasta or rice again is a surefire way to run out of steam in a few weeks.

Fortunately, It’s Skinny is a great way to make delicious meals that are as satisfying as their carb-heavy counterparts. You’ll get the taste and joy of eating pasta (or rice) with zero net carbs and only 9 calories per bag.

It’s Skinny is made with a fibrous vegetable called konjac root. This vegetable helps fill you up—keeping blood sugar levels steady. You won’t feel that carb spike and crash like you can get from other big, heavy pasta meals.

What’s more, It’s Skinny couldn't be easier to use. Open the pack, drain, rinse, and add it to your other ingredients when you're almost finished cooking. Once It’s Skinny heats through, in 2-3 minutes, you're ready to enjoy pasta your way.

It’s Skinny is available in four great styles:

  • Spaghetti
  • Fettuccine
  • Angel Hair
  • Rice

You can also get It's Skinny in organic varieties. All our styles are available in traditional as well as organic. Can't decide? Consider a variety pack. You'll each type of It's Skinny so that you can mix and match in any recipe.

For this deconstructed low carb lasagna, we use our widest fettuccine noodles. They make a great swap for the wide traditional lasagna noodles without the fuss, muss, or carbs. In literal minutes, you'll get all the yummy, gooey cheese lasagna flavors—even on a weeknight!


Sometimes, when you find a great recipe, you're inspired to make a few additions and changes! We've got you! We encourage you to customize, play around, and have fun in the kitchen! After all, mealtimes should be joyful and exciting!

Are you looking for customization ideas? Here are a few swaps and tricks to help you make this recipe your own.


Craving a more traditional lazy lasagna recipe? You can add any sort of meat to this recipe, or check out our traditional deconstructed lasagna recipe for the classic riff with meat sauce. This recipe goes well with ground beef, ground chicken, or turkey. You could add crumbled sausage, too, if you're looking for a spicy option.

Soy crumbles or meatless meat would be appropriate in this recipe if you’d like to keep it vegetarian. However, keep in mind that some types of vegetarian meat substitutes can be high in carbohydrates. If you are watching your carb intake on a keto diet, you’ll want to calculate the difference carefully. Sauteed tofu or walnut "meat" can also be a nice choice to keep carb counts low.


We've got spinach, zucchini, and mushrooms, along with a garlic and onion marinara sauce, making this vegetarian lasagna veggie-rich! But if you want to get in a few more vegetables (or swap out for your favorites), others could play well in this recipe. Eggplant slices could be nice. We use basil leaves, but any fresh herbs—oregano, marjoram, rosemary, and parsley would also be delicious here. It's all about the Italian seasoning. You could spice things up with red pepper, too.

Artichokes, broccoli, broccolini, bell peppers, and even asparagus would be a nice addition to this vegetarian lasagna. Cauliflower and Brussels sprouts may be too chunky for the sauce, but you could certainly use finely chopped vegetables of any sort. Broccoli slaw, for example, can cook down and add extra veggies to your sauce. You could also try cabbage, kale, or another leafy green in place or in addition to spinach.


Love cheese? We do too! You can indulge in a more decadent, richer sauce when you go low carb! While the recipe's ricotta, mozzarella, and parmesan combination makes it taste like classic lasagna, you could use many different cheeses and even cream to make the sauce richer.

Consider adding heavy cream to the tomato sauce. You could swap the ricotta for cottage cheese if preferred. Cream cheese can also work in this recipe in a pinch (look for a herbed variety for extra flavor). Mozzarella melts like no other, but provolone would also be a good choice. You could use Burrata or Gouda too. Pecorino is typically the closest swap for parmesan.


Ready to make this vegetarian pasta dish? It has all the delicious comfort food flavors of your favorite vegetable lasagna, but it’s fast and easy to bring together. With zero net carb It’s Skinny Fettuccine, there’s no guilt in indulging in this yummy Italian meal!
