Easy Spinach Lasagna
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!
But you can also include slices of cooked Italian sausage to add another layer of flavor to your Spinach Lasagna Recipe.
Why You Must Make
- This lasagna recipe was featured on Cook’s Country TV which tests their recipes thoroughly before sharing them.
- It’s perfect for vegetarians.
- You can also jazz it up for carnivores by adding in some sauteed, sliced Italian sausages!
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 online.
Ingredient Notes
- Kitchen Staples – Olive Oil, Kosher Salt, Black Pepper, Eggs (large), Onion, Garlic Cloves
- Frozen Chopped Spinach – 3 10-ounce packages, defrosted and squeezed dry
- Crushed Red Pepper Flakes – Adjust depending on your heat tolerance.
- Canned Crushed Tomatoes – 2 28-ounce cans
- Fresh Basil – Chopped
- Ricotta Cheese – Use full fat for the best flavor. You could also substitute Cottage Cheese which will make a creamier filling.
- Grated Parmesan – Make sure it’s not the powdery stuff in the green can on the store shelves. Look for real Parmesano Reggiano for the best flavor.
- No Boil Lasagna Noodles – Extra liquid in the sauce will hydrate them as the dish cooks.
- Mozzarella Cheese – Full fat and shredded.
- Mild Italian Sausage Links – Optional. Omit if making a vegetarian entree. Slice and saute to elicit the Maillard reaction which provides delicious flavor to browned food. Omit for a vegetarian version.
Recipe Tips
- 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 which save you a step and cleaning 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 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.
- Defrost your frozen spinach overnight in the refrigerator. Squeeze dry before using. You can use a potato ricer, press and squeeze in a strainer, or squeeze over a bowl with clean hands.
- Use a good quality jarred marinara sauce if you’re short on time. You will probably need at least 2 jars.
- Saute some sliced mushrooms in butter or olive oil if you’d like to add them to the tomato sauce.
Frequently Asked Questions
There are a few things that make this a simple lasagna recipe. First are the no-boil lasagna noodles. They absorb liquid from the sauce to hydrate, eliminating the need to boil and cool them before using them. Then, since this is a vegetarian lasagna, there’s no need to get out another pan to cook ground beef or sausages. And, finally, using frozen chopped spinach entails defrosting and squeezing it dry instead of cooking and chopping, then squeezing out the excess liquid.
Ricotta is a soft Italian cheese that’s often used in lasagna. My mom used cottage cheese and that’s probably the best alternative. Other options include cream cheese, sour cream, tofu, and even goat’s cheese or yogurt.
Yes, it should be cooked and chopped. Purchasing frozen, chopped spinach eliminates those steps. You will only need to defrost and squeeze out all the excess liquid.
Using a ricer works well, though it’s difficult to clean. You can also hand squeeze it with well-washed hands. I do that method over a strainer in the kitchen sink.
Leftover lasagna will keep for 3-4 days covered in the refrigerator as long as it hasn’t been left out on the counter for more than 2 hours. Cover with plastic wrap and reheat it at 350° for 30-40 minutes. You can also microwave single slices until heated through.
You can also freeze your lasagna, wrapped airtight, for up to 3 months. Defrost overnight in the refrigerator before reheating.

Instructions
- Preheat oven to 375º.
- Microwave spinach in a covered large bowl until completely thawed, about 15 minutes, stirring halfway through.

- Heat oil in a 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.

- Stir the ricotta mixture into the remaining processed spinach.
- Cover the bottom of a 13 by 9-inch baking dish with 1 ¼ cups of sauce. Top with 3 noodles and spread one-third of the ricotta mixture evenly over the noodles.

I’ve made a similar recipe but with homemade thin noodles and the flavours were awesome! You should try letting it rest overnight in the refrigerator and then slicing and reheating by frying the slices on their side, the noodles get so crispy on the edges, sooooo good!
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.
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)!
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!
Always a crowd pleaser. I love a delicious and easy lasanga. 🙂 ~Valentina
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.
I just love home made lasagna, though we have never made spinach lasagna before 🙂
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!
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!
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.
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!
Love this Liz! With a link of Italian sausage on the side, I’m sure Manservant would devour it. I know I would!
Great recipe! I would love to make this with goat cheese as a sub for the ricotta. Thanks, Liz.
This makes a perfectly comforting and delicious weekday meal.
This spinach lasagna is going to be on dinner repeat!! It’s so hearty and delicious!
