This Easy Spinach Lasagna is my go-to vegetarian lasagna. Layers of sauce, no-boil noodles, spinach ricotta & cheese combine for a tasty meatless meal!

Easy Spinach Lasagna

I caught an episode of Cook’s Country TV one Saturday when they featured this Spinach Lasagna. Knowing any sort of spinach pasta would be a huge hit with my daughter, I printed off this easy spinach lasagna recipe while it was still available on-line.

To make the resident carnivore happy, I  often tweak the recipe by sauteing some mild Italian sausages and added slices to half the tomato sauce. It uses no-boil pasta, so that decreases the dishes by at least one pot. But the food processor is needed to finely chop the spinach and mix some of it with the ricotta. Still, even with the usual array of dirty dishes, it was worth it for a dinner that all 3 of us enjoyed.

What Makes This An Easy Lasagna Recipe?

Well, you will have some dirty dishes and utensils, but there are a couple of reasons this is an easy lasagna. First, it’s a vegetarian lasagna, so there’s no need to fry up any ground beef or sausage. The tomato sauce is cooked, though, so there will be only one pan to clean.

Also, you’re using No-Bake lasagna noodles. If you haven’t tried them before, they absorb liquid from the sauce while the lasagna is in the oven, thus omitting the need to boil up the pasta.

Instead of chopping and steaming loads of fresh spinach, just defrost and squeeze dry three boxes of frozen chopped spinach. Easy as can be!

Tips for Making this Vegetarian Lasagna Recipe

  • For the meat lover in your home, add some sliced sauteed Italian sausage to the sauce. I’ve made this recipe with half sausage and half without.
  • Look for No-Boil lasagna noodles and that saves you the step and the pan needed to make traditional pasta. There’s enough liquid in the sauce to plump up the pasta as it cooks.
  • Though you have to break out your food processor, it’s used twice. Once for finely chopping the spinach and again for mixing part of the spinach with the ricotta, etc.
  • PRO-Tip: Grease one side of your foil so that the cheese will not stick as the lasagna cooks. I love non-stick foil as it saves a step, but spraying Pam on regular foil works well, too.
  • PRO-Tip: If you don’t have fresh basil, you can substitute 1 teaspoon dried basil for each tablespoon of fresh basil.

How to Prepare the Spinach

As mentioned above, I defrost boxes of frozen spinach overnight in the refrigerator. It’s already chopped but does need to be squeezed dry. I’ve used my potato ricer to extract all the liquid,  but the resident dishwasher complained about the tedious cleaning process. So now I get out a plastic strainer, add the spinach, and press down with a spoon or rubber spatula to remove as much moisture as possible. Then, I squeeze handfuls of the spinach with my scrupulously clean hands to eliminate any remaining liquid.

What Can I Use Instead of Ricotta?

If you can’t find ricotta cheese or run short, you can substitute cottage cheese. In fact, the lasagna my mom used to make when we were kids, always had a layer of cottage cheese. Ricotta wasn’t so easy to procure in a small Iowa town in the 70s!!! Other suggestions include cream cheese, goat cheese, mascarpone, sour cream, and even tofu. But cottage cheese would be my first choice.

Spinach Lasagna

A hearty, scrumptious pasta dish laden with spinach adapted from Cook's Country

Prep Time 30 minutes
Cook Time 50 minutes
Total Time 1 hour 20 minutes
Yield 8 servings

Ingredients

  • 3 10-ounce packages frozen chopped spinach
  • 2 tablespoons olive oil
  • 1 onion, finely chopped
  • 5 garlic cloves, minced
  • 1/8 teaspoon crushed red pepper flakes
  • 2 28-ounce cans crushed tomatoes
  • Kosher salt
  • Freshly ground black pepper
  • 6 tablespoons chopped fresh basil, divided
  • 3 cups (24 ounces) ricotta
  • 1 1/2 cups grated Parmesan
  • 2 large eggs
  • 12+ no-boil lasagna noodles
  • 3 cups (12 ounces) shredded mozzarella
  • 3-4 mild Italian sausage links, sliced and browned, optional for a non-vegetarian version

Instructions

  1. Preheat oven to 375º. Microwave spinach in covered large bowl until completely thawed, about 15 minutes, stirring halfway through. Squeeze spinach dry, reserving 1/3 cup liquid. Pulse spinach in food processor until ground, 8 to 10 pulses, scraping down bowl every few pulses. Wipe out large bowl with paper towels. Transfer spinach to now-empty bowl; set aside.
  2. Heat oil in large saucepan over medium heat until shimmering. Add onion and cook until softened, about 5 minutes. Stir in garlic and pepper flakes and cook until fragrant, about 30 seconds. Add tomatoes, ½ cup processed spinach, 1 teaspoon salt, and ½ teaspoon pepper and cook until slightly thickened, about 10 minutes. Off heat, stir in 3 tablespoons basil; set aside.
  3. Process ricotta and reserved spinach liquid in food processor until smooth, about 30 seconds. Add Parmesan, remaining 3 tablespoons basil, eggs, 1½ teaspoons salt, and ½ teaspoon pepper and process until combined. Stir ricotta mixture into remaining processed spinach.
  4. Cover bottom of 13 by 9-inch baking dish with 1¼ cups sauce. Top with 3 noodles and spread one-third of ricotta mixture evenly over noodles. Sprinkle with 2/3 cup mozzarella and cover with 1¼ cups sauce and sprinkle with sausage pieces, if using. Repeat twice, beginning with noodles and ending with sauce. Top with remaining 3 noodles, remaining sauce, and remaining 1 cup mozzarella.
  5. Cover pan tightly with aluminum foil sprayed with vegetable oil spray and bake until bubbling around edges, about 40 minutes. Discard foil and continue to bake until cheese is melted, about 10 minutes. Cool on wire rack for 30 minutes. Serve.

  1. Even though I’m not a great fan of spinach, I’m almost certain that I will like it in this dish. Bye-bye my diet, hello spinach lasagna=)

  2. Hey, something my dad could eat. All I’d have to do is remove the garlic and onions because he hates those for some reason. ._.

  3. I would have to add the sausage for my resident carnivore, too. Looks delightful, though. Never met a lasagna I didn’t like, er, love. Hope your new year is off to a great start, Lizzy. Your photographs are absolutely gorgeous.

  4. Love the combination of pleasing the daughter and the carnivore. Paul would be very appreciative of the sausage links! Saving this – such comfort on a winter’s night. Happy 2013!

  6. Look amazing!!!! Happy new year dear Lizzy and lots of beauty recipes like always you make!

  7. This has got to be the most perfect spinach lasagna I’ve EVER seen. I love adding spinach to lasagna – and really, any pasta dish. I want a huge chunk of this for lunch today!

  8. Lizzy, this looks fabulous. I never tire of Italian or Asian. Your piece is cut perfectly too, I never seem to have a neat looking lasagna that is picture-worthy – BRAVO!

  9. Wow, you got your lasagna to hold together perfectly. What a fabulous-looking dish!

  10. This looks like the perfect cold-weather comfort food dish! Love all those cheesy layers, and major kudos for making one of the ugliest foods so beautiful!

    I love a good, hearty lasagna, and this looks like it fits the bill. Yum!!

  17. trying to find meat free dishes that hubby would like and believe this would work. I don’t buy no-boil noodles. learned a trick eons ago from a friend to just use reg. noodles and maybe a bit more sauce. It bakes up great and is easier to slice. Thanks for the recipe, am new to your site and looking forward to recipes from you this year.

    • I hope your hubby likes this lasagna…mine did! I use that same trick with dried pasta…sure is easier than boiling! Glad you found your way to my blog 🙂

  18. Now this is what I call a LA-SA-GNA!! Wow… it’s beautiful. Mine always falls apart and it never serves up so perfectly. Gorgeous job!!

    PS… my resident carnivores would approve of your tweaking with sausage. 🙂

  19. Liz this looks delicious! I love spinach lasagna and haven’t made it in years. My family is funny about eating too much pasta something I’ve been craving lately. Thanks for the recipe, I’ll definitely try it.

  20. You’re right – I had to subscribe to your blog again. Which I just did. We now have an 11-year old vegetarian living in our family (thank goodness her Iowa great-grandparents are not alive to know this). This spinach lasagna minus the sausage looks delicious. She’ll love it. As will her mother.

  21. I as crazy about spinach as Popeye the Sailor Man! And I’d love to make this to add it to my lasagna repertoire! Delicioso Liz! I think that you just may have an Italian gene inside of you! Sorry for not commenting lately (I HAVE been reading each post tho) . . . Dad in Mary Greeley, double pneumonia, influenza and cancer . . . this is where we’ve been throughout Christmas. Stopped in Indiana for word to return to IA, but he stablilized and we moved on to SC. He’s out of ICU and will be in the ‘pital for at least another week. So that’s why I hadn’t posted or commented in the last week. I promise to catch up on your delicious posts . . . pinky promise!

    Happy New Year!

    Hope you are off to a great 2013!

  51. Lizzy, this is just gorgeous!! You are so very talented. I love spinach lasagna and much prefer it over the meat version!

  52. Maybe it’s just the time of year, but lasagne sounds soooo good right now. I’d take half of the pan of your spinachy goodness Liz.

    Happy New Year and good luck to the Pack this weekend!

  53. I was vegetarian for 3 years and although I now eat meat, I STILL prefer a vegetarian lasagna. SO good. This one looks perfect 🙂

  54. I’m with the carnivore, I like a little sausage in my lasagna, lol. I love lasagna, a little too much if you know what I mean. Usually my will power doesn’t last long and I should be ready for one soon. Hope you are having a wonderful week Miss Lucky Lizzy!
    -Gina-

  55. Lizzy, I’ve never worked with frozen spinach. Would fresh spinach be just as good in this, do you think? We also use another green called Silverbeet instead of spinach quite often – it has a slightly stronger taste than spinach. Hope you are having a good week.

  56. Lasagna can be hard to photograph but you nailed it, looks delicious Lizzy!!

  57. Lizzy, are you ok? Just noticed you haven’t posted for a while! Hope it’s because you have been having a nice holiday and not something not as nice. Take care. Hope you see you soon.

  58. I’m a huge spinach fan – maybe watched too much Popeye growing up. This would be a hit for the winter-that-will-not-go-away. And we would all do this meatless (although meat is good, too).

  59. My son loves lasagna, but guess what? I’ve never eaten it in my life!! To me, Lasagna is Garfield’s food! I can’t bear to fight with him. Hahaha!

  60. With ricotta, parmesan and spinach – this has to be deliciously good! Love spinach and love lasagna so this is a perfect combo for me!

  61. This spinach lasagna is going to be on dinner repeat!! It’s so hearty and delicious! 

  62. This makes a perfectly comforting and delicious weekday meal.

  63. Great recipe! I would love to make this with goat cheese as a sub for the ricotta. Thanks, Liz.

  64. Love this Liz! With a link of Italian sausage on the side, I’m sure Manservant would devour it. I know I would!

  65. I will definitely not miss meat in this lasagna…love vegetarian lasagna and spinach is one of my favorite.
    Have a great rest of the week Liz!

  66. We love sneaking in vegetables any way we can. Your delicious lasagna with the spinach is right up our alley. Hiding those veggies like a pro and smothering them with cheese and sauce, no one will ever know.

  67. Your lasagna looks delicious! I love your tip to spray the foil wrap with cooking oil. I will try that trick next time I make lasagna.  Thanks so much! 

  68. I love spinach lasagna, but my Bill would have to have his standard meat in his. Geesh! I’ll make it for myself though, any day! Stay safe my friend!

  69. I just love home made lasagna, though we have never made spinach lasagna before 🙂

  70. This looks like a wonderful lasagna and it is worth all the dirty dishes. Last year our 89 year old neighbor made a similar one for us. It was delicious. 

  71. Always a crowd pleaser. I love a delicious and easy lasanga. 🙂 ~Valentina

  72. I would say that this doesn’t really need the Italian sausage, but … Italian sausage adds SO MUCH to a dish I can see how it would take this already delicious lasagna up a notch or two. Beautiful dish Liz!

  73. Dear Liz, a beautiful spinach lasagne like yours is very hard to beat. I often make a vegetable lasagne for us and spinach is the most popular. I usually pair it with an antipasti assortment and make the meat-loving eaters in our family happy, as they nibble on Italian salami and/or prosciutto. But adding slices of mild sautéed Italian sausages to one half of the dish is a pretty delicious idea as well! I will certainly remember that tip for the next time I make veggie lasagne.
    Happy Pentecost (Frohe Pfingsten)!

  74. I think the first lasagna I ever made was a spinach one. I do love the No-Boil lasagna noodles, I think they make a lighter lasagna. Our husband’s sound alike, add a little sausage and they love it.
