Tomatoes are rich in one of the most powerful antioxidants found in nature. Lycopene. So what makes antioxidants so great? Antioxidants are those substances we get from our diet that help keep our brain, heart, muscle, and liver healthy.

Adding antioxidants to your diet in the form of tomatoes is one way you can combat the free radicles in your body and protect your brain, heart, muscles, and liver from damage by free radicles. You’ll enjoy a longer, healthier life when you eat foods high in antioxidants.

Ingredients for the Marinara Sauce

Make the Pasta Sauce
I love the smell of a pot of homemade marinara sauce simmering on the back burner. This recipe is a great simple and easy basic sauce. It’s delicious as a marinara sauce over pasta or in your lasagna recipe. If you like a hearty meat sauce, like farmer Fred, add some meatballs and sausage to the sauce while it simmers.
To make the homemade pasta sauce, I used canned garden tomatoes that I pureed before adding them to the sauce kettle. Instead of home canned sauce you may want to purchase crushed tomatoes as they are a great substitute for the home-canned tomatoes. To make the sauce, saute the garlic and add all of the ingredients to the tomato sauce. Use fresh herbs whenever possible.
If you don’t have fresh herbs, use 1 tsp. of each herb if you are using dried herbs. Simmer for two hours. Prepare the ingredients for the Vegetarian lasagna while the sauce is simmering.

Ingredients for the Vegetarian Lasagna
- Marinara Sauce from above.
- Lasagna Pasta: Use some whole grain pasta or gluten free pasta if you are gluten free.
- Spinach: Frozen and thawed spinach or blanch fresh spinach.
- Plant Based Meat: Any variety of plant based meat. You can use sausage or a combination of both.
- Sour Cream or plain greek yogurt
- Cheese: Mozzarella, Mixed Italian blend, and parmesan cheese.
- Ricotta Cheese: Either low fat or full fat.
Make the Vegetarian Lasagna
Prepare the ingredients:
- Grate the Mozzarella and Parmesan cheese and set aside.
- Saute the plant-based sausage with the onions and garlic until the sausage browns, and the onions are translucent. Set aside to cool.
- Cook the Lasagna noodles in a large pot of boiling water. I add about a tbsp of oil to the water. This prevents stuck-together noodles when it’s time to assemble the lasagna. If the noodles are still sticky, I toss them with a bit of olive oil and lay them out flat.
- Steam-cook the fresh spinach in a bit of water. Press the cooked spinach between two kitchen towels to remove as much moisture as possible. Chop the cooked spinach before adding it to the Vegetarian Lasagna.


Assemble the Vegetarian Lasagna
First Layer:
- Spread two cups of sauce in the bottom of a lightly greased 9 X 13-inches deep dish baking pan. A deep-dish pan works best. However, I use a regular baking pan as well. I used a regular baking pan in this recipe.
- Add a layer of cooked lasagna noodles on top of the sauce. I use 1/3 of the total number of noodles in each layer.
- Add half of the plant-based sausage mixture.
- Add half of the spinach.
- Add 1 cup of ricotta cheese. Scatter rounded teaspoons full across the top of the pasta noodles. Add 1/2 cup of the sour cream.
- Top with one and 1/3 cup of the grated mozzarella cheese and 1/3 of a cup of parmesan cheese.
- Add two cups of marinara sauce.
Second Layer:
- Top the bottom layer with more lasagna noodles and repeat the above steps for the vegetarian lasagna ingredients.
Top Layer:
Add the last of the lasagna noodles, the rest of the sauce, and the rest of the grated mozzarella and parmesan cheese.

Baking, Storing, and Freezing the Lasagna
- Cover the Vegetarian Lasagna with lightly sprayed aluminum foil. Bake the Lasagna for 30 minutes at 350-degrees F. Uncover and bake another 30 minutes or until the center is hot and bubbly.
- Freeze uncooked lasagna for up to two months. Tightly cover the pan before freezing. Defrost overnight and bake as above.
- Store leftover lasagna in the fridge. Leftovers reheat well in the oven or microwave.
- Create a yummy appetizer with the leftovers. Make Fried Lasagna Bites.

FAQ for Lasagna
What can I substitute for meat in lasagna?
There are plenty of delicious meat substitutes that can be used in place of the traditional ground beef. One popular option is using mushrooms as a meat replacement. Their meaty texture and earthy flavor make them a great choice. You can either finely chop them or sauté them to mimic the texture of ground meat.
Another option is using lentils, which have a similar texture to ground beef when cooked. They absorb flavors well, making them a tasty addition to any lasagna. For a more plant-based alternative, you can use tofu or tempeh, which can be crumbled and seasoned to resemble ground meat. Freeze them first and then defrost and crumble them.
How do you keep veggie lasagna from getting soggy?
The key to preventing soggy lasagna is to ensure that your vegetables are cooked adequately before assembling the lasagna. This will help remove any excess moisture from the vegetables, preventing them from releasing water during baking. Another tip is to use a thicker tomato sauce or add some tomato paste to your sauce to help absorb any excess moisture. Also, let your lasagna rest for 10-15 minutes after removing it from the oven. This will allow the layers to set and firm up, reducing the chances of it becoming soggy.
Does lasagna in Italy have meat?
Traditional Italian lasagna, known as Lasagna alla Bolognese, contains meat. It is typically made with layers of thin pasta sheets, a rich and flavorful meat sauce made with ground beef or veal, and a creamy béchamel sauce.
However, it is essential to note that there are variations of lasagna throughout Italy, and some regions may have their unique versions that do not include meat. For example, in the southern regions of Italy, lasagna may be made with a tomato-based sauce and vegetables instead.
What does veg lasagna contain?
This mouthwatering dish is made up of layers of pasta sheets, rich tomato sauce, and a variety of flavorful vegetables. The most common vegetables in veg lasagna include bell peppers, zucchini, mushrooms, and spinach.
Additionally, veg lasagna often contains a generous amount of creamy ricotta cheese, which adds a creamy and savory element to the dish. Lastly, the whole dish is topped off with a generous layer of gooey melted cheese, creating a golden-brown crust that is simply irresistible.
How many layers should a lasagna have?
Traditionally, lasagna is made with three layers – a bottom layer of sauce, a middle layer of pasta sheets, and a top layer of cheese. However, some people like adding even more layers to their lasagna, creating a towering dish bursting with flavor.
Whether you stick to the classic three layers or go all out with six or more, the key is to ensure each layer is well-balanced and packed with delicious ingredients.
Should you boil lasagna sheets first?
Some argue that boiling the sheets ensures they cook evenly and prevents them from becoming too tough. On the other hand, some believe that the sheets will cook perfectly in the oven without any prior boiling. So, what’s the verdict? Well, it ultimately depends on personal preference.
If you prefer a softer texture and want to ensure that your lasagna sheets are fully cooked, boiling them beforehand might be the way to go. However, skipping the boiling step is perfectly fine if you like a slightly firmer texture and don’t mind a bit of chewiness.
How do you make lasagna stay firm?
One essential tip is to let it cool and set before cutting into it. This allows the layers to settle and bind together, creating a firmer texture. Another trick is to use enough sauce but not too much. Too much sauce can make the lasagna soggy, so strike the right balance.
Additionally, using a combination of ricotta cheese and eggs in the filling can help provide structure and maintain the firmness of the lasagna. Lastly, don’t be afraid to experiment with different types of noodles or even add breadcrumbs on top for an extra crispy finish.
