Ingredients & substitutions

  • Eggs: Beaten eggs are mixed with the ricotta to allow it to set, so that it doesn’t ooze out when you cut into the lasagna.
  • Cheese: Use ricotta, parmesan and mozzarella to make this tomato lasagna. The ricotta adds a great creamy texture, the parmesan gives a stronger and sharper cheese flavor and the mozzarella creates those perfect cheese pulls.
  • Seasoning/Aromatics: Fresh basil, fresh garlic salt and pepper.
  • Spinach: This adds vegetables to the tomato lasagna to bulk it up for the meatless option.
  • Lemon: The lemon juice and lemon zest add a burst of fresh flavor, and the acid helps to cut through the creamy ricotta.
  • Tomatoes: Heirloom tomatoes are perfect for the lasagna as they are so much more flavorful than regular. In a pinch, large beefsteak tomatoes, or vine-ripened will work well. slice them and layer them with the other ingredients.
  • Lasagna: Use no-boil lasagna sheets for this recipe. The moisture in the rest of the dish will cook the sheets.
  • Tomato sauce: Use plain tomato sauce for that authentic lasagna flavor or make your own marinara from scratch.

Tips for making the recipe

  1. Place the lasagna over a sheet pan in the oven. This is a great little tip to keep your oven clean when baking lasagna. The sheet pan helps to catch any bubbling sauce.
  2. Make it faster by not cooking the garlic and spinach. Since the garlic and spinach cook together in the oven with the lasagna, you can skip the initial saute. But if you have time, this allows the garlic to release more of its flavor and the wilted spinach is easier to mix.
  3. Use no-boil lasagna sheets for ease. They are much easier to work with and can be added straight to the dish. If you use lasagna sheets that need to be boiled first, be careful not to overcook them, or they will become very soggy in the dish. Boil them for 4 to 5 minutes before draining, cooling and adding to the dish.
  4. Cover the lasagna when you bake it. If your lasagna is baked uncovered, it can turn out quite dry as the steam will escape. Keep it covered and then broil quickly under the broiler for the last few minutes.

Frequently asked questions

How long does it keep?

Lasagna is a great dish to make, as you can make up a big batch and enjoy it a few times throughout the week for easy to grab lunches and dinners. It will keep well in the fridge for up to 5 days, and can be reheated in the oven at 360F, covered with foil to warm through.

You can make up the lasagna a day ahead of time and keep it covered in the fridge until you are ready to cook.

Can you freeze it?

You can freeze the lasagna for up to 3 months, either cooked or uncooked. You can defrost cooked lasagna in the fridge overnight before reheating or cooking. An uncooked frozen lasagna will take about 10 more minutes to cook through.

What do you serve it with?

This tomato lasagna is great to serve with a fresh side salad like:
Tomato Caprese Salad
Green Goddess Salad
Feta Crouton Salad
Pesto Zoodles

Ingredients
  

  • Nonstick cooking spray
  • 1 tablespoon olive oil
  • 4 garlic cloves minced
  • 1 5 ounce bag baby spinach
  • 2 eggs
  • 1 15 ounce container ricotta cheese
  • 1 cup fresh grated Parmesan cheese divided, plus more for garnish
  • ¼ cup fresh basil chopped, plus more for garnish
  • ½ lemon zested and juiced
  • 1 teaspoon Kosher salt plus more to taste
  • freshly cracked black pepper
  • 4 large heirloom tomatoes sliced into ¼-inch planks
  • freshly cracked black pepper
  • 12 lasagna sheets no-boil
  • 1 15 ounce can tomato sauce
  • 3 cups shredded mozzarella cheese

Instructions

  • Preheat the oven to 375°F and set an oven rack in the middle and upper third of your oven. Spray a 13×9 baking dish with cooking spray.
  • In a large skillet, heat oil over medium heat. Add garlic and cook until fragrant, 1 minute. Add spinach and cook until wilted, 4 minutes. Remove from heat.
  • In a medium bowl, whisk the eggs. Then stir in the ricotta, ½ cup grated Parmesan, basil, cooked spinach mixture, lemon zest, lemon juice, 1 teaspoon kosher salt, and black pepper.
  • Arrange ½ of the heirloom tomato slices in a single layer on the bottom of the prepared baking dish, reserving the “prettier” slices for the top of the baking dish.
  • In the baking dish with the arranged heirloom tomatoes, add a layer of the lasagna sheets (4 per layer), then ¼ of the tomato sauce, then ¼ of the ricotta mixture, and ¼ of the mozzarella cheese. Repeat this sequence 3 more times, reserving the final ¼ of mozzarella cheese. Top final layer of ricotta with remaining ½ of pretty heirloom slices and remaining ¼ of mozzarella and remaining ½ cup grated Parmesan.
  • Spray a sheet of aluminum foil with cooking spray and lay it, oiled side down, over the lasagna, covering the entire baking dish. Place the lasagna over a sheet pan (to catch any bubbling sauce) and bake in the center rack of the oven until sheets are fully cooked, 35-40 minutes.
  • Remove the foil and transfer to the top of the oven. Broil until the cheese is golden and crispy, 2-3 minutes.
  • Garnish with fresh basil and more Parmesan, if desired. Let sit for 10 minutes before cutting and serving.

Notes

Storage: Store any leftovers in an airtight container. They will last about 5 days in the fridge.
Freezing Instructions: You can also freeze the baked lasagna for up to 3 months. To re-heat, thaw in the fridge overnight and bake in a 350°F oven until heated through. You can also freeze the uncooked lasagna as I often do. Follow the baking instructions but leave it in the oven for an extra 10 minutes.

    hey. im in europe and having trouble converting your numbers. is that a 15 oz bag of spinach of 1 oz 5 grams??? also for ricotta and tomato sauce! HELP!

    1. Yumna Jawad says:

      It is one bag of spinach, which should have 5 ounces of spinach in it. It is one container of ricotta, which should weigh 15 ounces. It is one can of tomato sauce, which should have 15 ounces of tomato sauce in it. Hope that helps!

      1. Shanna says:

        This looks amazing, having so many of the ingredients I crave on a regular basis! I can’t wait to make it, I already know I will love it. What a wonderful alternative to the traditional, guilt inducing dish. Thank you!

        1. Yumna J. says:

          You’re so welcome! You’ll have to let me know what you think when you make it!

  2. Nina Makarem says:

    Another brilliant recipe. Followed it exactly as is and the whole family liked it. Thanks, wil def do it again!

    1. Yumna Jawad says:

      Wow, thank you so much! Yay!!

  3. Cheryl says:

    I picked this recipe because I needed to use up some heirloom tomatoes a friend gave me. I had to add Italian sausage because my hubby wasn’t thrilled at the idea of a veggie lasagna but everything else was the same. It turned out really good, and he went back for seconds. Thanks for the great recipe!

    1. Yumna Jawad says:

      That sounds like a great way to make it work for the both of you! Yay!! You’re so welcome.

  4. Keith Labrecque says:

    What happens with the onions?
    And what’s up with all the commenters’ mushroom omissions? I saw no mushrooms mentioned in the write up.

    1. Yumna Jawad says:

      No onions in this recipe – thank you for spotting that! Not so sure about that one haha.

  5. Sheila says:

    Hi Yumna can I omit the eggs ??? My son is allergic. Thank you

    1. Yumna Jawad says:

      Hi! I haven’t tried this with an egg substitute yet because the eggs mixed with the ricotta allow it to set. I usually substitute eggs with flax eggs in a recipe, but I have yet to give that a go here.

  6. Lana says:

    I’m very pleased with the way it turned out. I used half yogurt and half ricotta mixture, I didn’t have any mushrooms and I added some shredded mozzarella to yogurt mixture. It’s a great way to use those beautiful garden tomatoes. I made it for a company and everyone loved how pretty it looked and how fresh tasting it was. Thank you so much for this recipe!!!

    1. Yumna Jawad says:

      Yay! I’m still glad it worked out that way and that everyone enjoyed it too. You’re so welcome!

  7. L says:

    I had been looking for a lighter lasagna recipe for summer. This was fantastic! I made mine using the ricotta. I made mostly as directed, but I also added 2 ounces of parm to the ricotta-spinach mixture, I didn’t spray the top with cooking oil, and I left out the mushrooms. Next time I would bake bread to sop up all of the delicious tomato juice that bakes out of the heirloom tomatoes. Sadly I didn’t think of that this time, so I ended up dumping the extra tomato juice out of the pan before storing the leftovers (I didn’t want them to get soggy).

    We will def make this again! Thank you for such a great recipe!

    1. Yumna J. says:

      That sounds lovely! Definitely go with the bread idea next time too. You’re so welcome!

  8. Kevin Helwig says:

    Why didn’t you post your tried and true lasagna recipe on this website? Now, unfortunately, I have to look elsewhere.

    1. Yumna Jawad says:

      Hi Kevin – I actually had this post drafted for a very long time and never posted it. I’m so happy you mentioned it because it really needs to be on my site. And thanks to your reminder, it’s actually published now here:

      1. Kevin says:

        Thank you! I look forward to to trying it. I like your website and have turned some of my buddies on to it. As an ex-athlete, I am moving to a more plant based diet and I appreciate the ways you mention how to modify recipes to accommodate different diets in the recipes. Your flavors are spot on and the nutritional benefits are significantly better. Keep it up!! Take care

        1. Yumna Jawad says:

          I’m so glad to hear that Kevin! Thanks so much for sharing and I love hearing feedback like that to continue providing more plant-forward recipes with great flavor. Thank you and wishing you happy holidays!
