Low-Carb Vegetarian Lasagna | No Pasta/Noodles Weight-Loss Friendly Mediterranean Vegetables Bake

While lasagna is extremely famous and popular, vegetarian lasagna is on the rise and I am sure many will appreciate this low-carb, no pasta or noodles, vegetarian version. 

This is another dish my mother would do occasionally while I was growing up in Italy and I absolutely love it!

It is extremely easy to prepare as it mainly has three ingredients: grilled vegetables, tomato sauce, and cheese.

You can call it mixed Mediterranean vegetables Parmigiana if you wish (which is what it is, essentially!).

This vegetarian lasagna is extremely versatile, as it can be used as a side dish when having a small portion or as a main dish when being more generous. It is very filling as it contains low-carb vegetables that are high in fiber and it is scrumptious as it has cheese layered in between. 

It is delicious either hot or cold and it can be prepared a day in advance and stored in the fridge to be either baked or reheated the day after.

Have a try at this delicious and colorful dish!

Let’s talk nutrition!

While it is easy to talk about peppers, zucchini and eggplant, as they are all low-carb vegetables, what many don’t talk about is the nutritional benefits of cheese and its fats and proteins.

Cheese is often associated with weight gain, as some types are high in fat, calories, and sodium, however, what most forget is that cheese is a great source of calcium and proteins, amongst many others! Some studies have shown how some cheeses may help prevent heart diseases and osteoporosis, with some even associating it to weight loss, however, some cheeses are indeed ‘healthier’ than others and mozzarella is one of them!

Mozzarella cheese is originally from Italy and it is usually made from cow or buffalo milk; its consistency is soft and it is extremely moist.

This cheese is a great option as it has less sodium and calories than most other cheeses, as well as still being rich in proteins.

Some bacteria contained in mozzarella act as probiotics; Lactobacillus Casei and Fermentum are found in it, which can be found as an additive in some yogurts and upsold because of this!

These probiotics found in this cheese may help improve the health of the human and animal gut, as well as assist the immune system and fight inflammation present in the body, such as respiratory infections.

Mozzarella is also rich in Vitamin B-7 (Biotin, which, for example, stops the nails from becoming brittle), B-2 (Riboflavin, required by the body for cellular respiration), B-3 (Niacin, converts fat into energy usable by the body) as well as Vitamins A, D, and E.

Questions time!

How to make vegetarian lasagna?

This low carb vegetarian lasagna is very easy to prepare and it can be divided into three simple steps:

• Prepare the vegetables: Wash, slice, and grill the vegetables on a non-stick grilling pan.
• Prepare a tomato sauce: heat a teaspoon of olive oil and gently brown some onion and garlic in it; once ready add either chopped tomato or passata with a bit of water, adjust the salt level and simmer on a low flame for about 15 minutes.
• Layer and bake: Starting with tomato sauce, layer the ingredients alternating vegetables, tomato sauce, and mozzarella cheese. Save some tomato sauce for the top layer and mix it with some parmesan cheese for a luxury topping! Bake for 30 minutes (15 minutes with some foil on top and 15 minutes uncovered) then allow it to sit for 10 minutes before serving. Enjoy!

Always remember to put a bit of tomato sauce before starting with the vegetables at the bottom, as this will prevent the vegetables from sticking to the bottom. 

Should you wish to make this a Light Eggplant Parmigiana, you can simply use eggplant only, instead of peppers and zucchini as well.

How to make vegetarian lasagna with spinach?

This vegetarian lasagna can be made with the addition of spinach; to do so, fresh spinach can be added to the tomato sauce once it is nearly done. Baby spinach is the best choice as it is not bitter and it can be mixed and lightly cooked in the tomato sauce for a couple of minutes before using it to layer the vegetables.

What other vegetables can I add to this mixed vegetable bake recipe?

This low-carb eggplant, pepper, and zucchini lasagna is already extremely rich per se, however other vegetables can be used for this recipe as well.

Large Portobello mushrooms can be grilled and added to the mix, as they are quite large and can be nicely grilled, as well as large slices of beef tomato.

The sauce can be bulked up with multiple ‘leafy’ vegetables, such as watercress or rocket, however, for a deeper taste, some leek can be added to the onion and garlic base, as well as some grated carrot.

Should one have all of these vegetables at home, I would not recommend using them all, as most times less is more! These Mediterranean vegetables complement each other nicely, and I’d suggest adding other vegetables only if there are not enough of the other ones or if one or more of the vegetables in the recipe are not liked.

How long can I store this low-carb lasagna?

This low-carb vegetarian lasagna can be stored in the fridge for 3 days once it has been baked; before putting it in the fridge, allow it to fully cool down and then cover with the container’s lid (I have a nice glass baking tray with matching plastic lid) or with cling film.

You can also prepare this day one day before baking, store it in the fridge, and bake as per the instructions.

This is the glass container with lid I like to use for lasagna, pasta bakes and savory bakes in general!

Can I freeze this vegetarian lasagna?

Yes, this low-carb lasagna can be frozen either baked or before baking. 

Should you wish to freeze it baked, then allow it to fully cool down before doing so; as this is a great lunchbox option, this is a great dish to freeze in single portions. Before reheating, allow the vegetarian lasagna to fully defrost and then either reheat it thoroughly in the oven or the microwave; always ensure the lasagna is piping hot before serving.

Should you instead wish to freeze it unbaked, you can do so easily; before baking though, ensure it is fully defrosted and then baked as normal. 

Why is this considered a low-carb vegetarian lasagna?

The main vegetables used in this recipe are all low carbohydrate ones: peppers, zucchini, eggplant, tomato, and onion, and they are used as a substitute for lasagna noodles/sheets. Should you still wish to use some pasta sheets, then perhaps alternate the layers so that not too much is added but the texture is felt through and through.

Can I make this vegetarian lasagna vegan?

Absolutely yes, and very easily so! 

To do so, you can either swap the cheese for a non-dairy alternative or the cheese can just be skipped altogether. Should you wish to simply skip the cheese, then perhaps try adding (as in a couple of questions above) some spinach to the tomato sauce for that extra something.

What can I serve this low-carb vegetarian lasagna with?

This dish can be eaten as a side or a main, so there are multiple dishes this can be served with!

If using as a main, serve it with a crunchy coleslaw made of grated carrots, thinly sliced cabbage, and onion and dressed with a little amount of mayonnaise (I like to use Calve’ or Hellmans, as one teaspoon is so tasty you won’t need more) or a sliced of toasted bread topped with a little homemade fluffy garlic butter.

If you’re serving this as a side, accompany it with a nice simple onion and black pepper omelet or with some scrambled eggs; if you are not following a vegetarian diet, perhaps try adding a small amount of crumbled chorizo to either egg option.

Again, for non-vegetarians, a grilled slice of chicken breast or a lean cut of pork is a great accompaniment.

Should you prefer to keep it light, try sautéing some button mushrooms in a bit of butter with garlic and parsley; you’ll only need a tiny amount of butter, but the garlic and parsley will elevate the mushrooms and make them a nice pairing for this dish as they will have that nice bite.

Rich layers of grilled vegetables, tasty tomato sauce and mozzarella cheese!

How can I modify this dish in different ways?

There are multiple ways this can be modified depending on taste, calories, dietary requirements, and what you have in the house!

Starting from the tomato sauce, flavors can be added in the form of spices and herbs; elevate it by adding some crushed red chilies, chopped basil, or parsley. If you’re looking for a bit of a bite and tanginess, add some chopped green or black pitted olives to it, or try a tablespoon of basil or sundried tomato pesto in it.

For the cheese, there are many options as well! Swap the mozzarella for some mild grated cheddar cheese, edam, or crumbled feta, and use Pecorino Romano instead of parmesan for the top layer!

You will love this recipe as it is easy to prepare, low in calories, tasty and vegetarian! 

This is a great dish to prepare and have in the fridge ready to warm up, but as well as a lunchbox filler to have on the go, either warm or hot!

The Mediterranean flavors, the delicious cheese, and the warming smell of tomatoes will fill your kitchen and you won’t turn back… low-carb and low-calorie options have never looked so tasty!
