What Is Vegetarian Lasagna?

Just like the name sounds, a vegetarian lasagna is a layered pasta dish that’s made without meat. Traditional lasagna is made with either ground beef or sausage (or a combination of the two).

This vegetarian lasagna is made without any meat. It’s a meat-free meal which is perfect to eat during Lent, or if you don’t eat meat in your regular diet.

Is it vegan? No, this recipe isn’t vegan. Since it’s made with cheese, it can’t be considered vegan. But if you want to make it vegan, just use a vegan cheese substitute.

Here are some tips and answers to common questions about baking homemade lasagna.

Add Marinara Sauce To The Casserole Dish

It’s very important that you add a base layer of marinara sauce to the casserole dish first. This will prevent the noodles from sticking to the dish.

Add Uncooked Pasta

You’ll add as many uncooked lasagna noodles as you can fit in your casserole dish. For me, it was six noodles.

Yes – you will add them to the dish uncooked. They will cook in the oven, in the sauce. This step saves you so much time!

Use Fresh or Frozen Spinach

It’s ok to use either fresh or frozen spinach in your lasagna. If you’re going to use frozen spinach, I suggest cooking it first and them removing as much water and moisture as you can.

Strain it and then use a paper towel to wring out more moisture. If you skip this step, the water will cook out of it and thin down the marinara sauce.

Layer With Plenty of Cheese

I used a combination of ricotta cheese and mozzarella cheese. These are the two types that you will most often find in lasagna recipes.

But you can get creative and use different types of cheese. Try a half and half combination of ricotta and cottage cheese. Or shred some Monterey Jack cheese instead of Mozzarella. You can even use soft goat cheese instead of ricotta cheese.

How To Tell When It’s Done

How do you know when meatless lasagna is done cooking? Since it’s made without meat, it’s perfectly safe to eat it without cooking (but no one will enjoy those crunchy noodles).

So, the best way to tell when it’s finished cooking is to try to cut into it. If the noodles are soft and cooked, it’s ready to eat!

How To Store Leftovers

How do you store leftover lasagna? This meal will taste delicious later in the week! Cut up the lasagna into smaller pieces and place them into an airtight container. Then, keep the container in the refrigerator for up to three days.

  • Make it spicier – add red pepper flakes
  • Use different veggies. Instead of spinach, add thinly sliced zucchini
  • Lasagna Noodles – These can be swapped too! Try it with a layer of rotini noodles instead
