Who could use a dinner idea that’s easy (like super easy), hearty, and delicious? How about the easiest lasagna recipe in the world?
Can I just start by saying this: frozen ravioli is a freezer must-have. It’s not like you can make that many meals with frozen ravioli, but it does make a pretty awesome weeknight lasagna. We’ve done a few variations over the years, but a good, marinara-sauced Ravioli Lasagna seems to be the favorite. And really, this is just baked ravioli, but saying lasagna makes it feel a little fancier, right? And it has all the basic components of lasagna — layers of noodles, sauce, and cheese. See? Lasagna it is. :)
It’s totally up to you which ravioli to use. I prefer to buy a basic ricotta ravioli and then gussy up the sauce when I want a variation. The recipe below is a sort of creamy Florentine-style sauce — frozen spinach (another time saver!) plus heavy cream and a good-quality bottled marinara. (Or you could make your own!) The addition of cream is the most recent change I’ve made to our tried-and-true recipe. It just sort of ups the flavor and decadent feel of the whole dish.
The ravioli doesn’t need to be cooked before making the casserole. It just goes straight into the baking dish from the freezer. We usually keep this meatless and sometimes I add mushrooms too. It really is as simple as opening a few packages and putting the pan in the oven.
While this is a quick and easy dinner to make on a weeknight, it’s also great to serve when you’ve got a crowd to feed. Simply double or triple the recipe as needed. Also, can I tell you that this is a great meal to take to a neighbor or friend? A friend with a newborn baby or who has a sick child or spouse. Or one who has had one of those weeks and could use a yummy dinner and a reminder that you’re thinking of them.
Creamy Spinach Ravioli Lasagna
2 tablespoons olive oil
1 small onion, diced
3 garlic cloves, minced
16 ounces frozen spinach
Salt and pepper, to taste
28 ounce jar marinara sauce
8 ounces heavy cream
2 pounds frozen ravioli, your favorite flavor, unthawed*
16 ounces shredded mozzarella
1 cup shredded or grated Parmesan
For serving: green salad
1. Preheat oven to 400° F. Lightly grease a large baking dish, such as a 9- by 13-inch pan.
2. In a large skillet, heat olive oil over medium-high heat until shimmering. Add the diced onion. Cook, stirring occasionally, until onion begins to soften, about 3-5 minutes. Add the garlic and cook for another 30-60 seconds. Add the frozen spinach to the pan. Cook for another 3-5 minutes, stirring occasionally. Season with a little salt and pepper.
3. Add the heavy cream to the spinach and stir well. Bring to a simmer and cook for a few minutes, then add the marinara sauce. Add more salt and pepper, if needed. Remove from heat.
4. Spread about 1/2 to 3/4 cup of the sauce on the bottom of the baking dish. Place an even layer of the frozen ravioli over the sauce. Pour one third of the remaining sauce over the ravioli layer, followed by 1/4 of the shredded mozzarella and 1/4 cup shredded Parmesan.
5. Repeat the process two more times with the remaining ravioli, sauce, and cheese.
6. Cover with foil and bake for 30-40 minutes. Turn heat up to 425°F and remove foil from pan. Continue baking for an additional 10-15 minutes, or until the top is golden brown and bubbly. Remove from oven and let stand, covered, for an additional 10 minutes before serving.
7. Serve warm with a green salad on the side.
Yield 6-8 servings.
– You can also use fresh ravioli. Cooking time will be about 15-20 minutes less.
– This recipe is meatless, but you could add 1 pound of cooked ground beef, turkey, or sausage to the sauce for a heartier casserole. Or you could use raviolis stuffed with meat as well.
This recipe is especially good because it’s so doable. It’s basically assembling ingredients in a casserole dish! Barely any prep at all. I feel like this could become a solid family reunion recipe — a great way to feed a bunch of people fast. It really is the easiest lasagna recipe ever.

Yum! This sounds totally yummy! Thanks for sharing :) Our go-to dinners change a lot depending on what I am stewing in large batches on the stove/crockpot. I like cooking large amounts of things like pasta sauce (loaded with veggies & sausage) or chicken soup or stew and freezing jars of it. I also recently learned I could steam the glass jars of frozen meals straight from the freezer without breaking! Maybe it depends on the jar, but so far my Ball mason jar has been surviving :) Right now our go-to meal is a green hatch chili chicken stew with diced tomatoes & corn topped with sour cream & some crushed tortilla chips. Shrimp tacos are another go-to since shrimp defrosts quickly & is quick to cook up.
I saw a recipe like this on pinterest but I think the spinach is a welcomed addition in our house!
“One of the things that stops me up from making lasagna is the pre-boiling of the pasta.” No-boil lasagna noodles are the bomb! And – here’s a secret – even regular lasagna noodles do not have to be pre-boiled. The baking in the sauce cooks them. That said, I make a similar ravioli casserole that is really delicious and easy.
I use regular lasagna noodles and don’t boil them first. This is my go-to lasagna recipe!
Me too, I never pre boil lasagne sheets, I use them dry and they cook in the sauce.
I am a slow cooker fan. I cook dinner five nights a week on average. (I work as an ICU doc and I have to prep in advance.) My teenagers love this coconut curry chickpea recipe. I make it once a week! I serve it with white rice cooked with 1/2 part water and 1/2 part light coconut milk.
My other standby is this one skillet yellow rice chicken dish. I always have chicken thighs and peas in the freezer so I can make this on the fly. The garlic, cinnamon, turmeric, and cumin make this SO good.
Thanks for these suggestions, Michelle. I have to eat milk- and soy-free (boo) for my breast-feeding son, and these both work well for my diet. I will definitely be trying them. :)
I made the yellow rice chicken dish a few days ago. My family of seven loved it. I had two batches going side by side because I was worried about doubling it first try. SO easy. Anyone interested in a delicious, one-pan meal must try it! The chicken was so tender and rice was cooked to perfection. Thanks Michelle!
It would be great fun to have a post on these quick meals like Michelle makes. You could ask for suggestions, and we could add links to our favorite quick meals. The ravioli lasagna was great… and I want to try the 2 that Michelle mentioned. Especially at this busy time of year these recipes are very wonderful!!
Love this idea, GiGi! I’ll see what I can whip up.
Kelly, isn’t that yellow rice dish amazing! (When I have zero energy, I can still throw that meal together.)
Can’t wait to hear what you think!
Wow, My wife and I have making this for years, we substitute browned hamburger for spinach and use 4 cheese ravioli. We got the recipe from Instructables.com about 6 years ago. Been a favorite since day one
I made this recipe last night, and it was truly delicious!
Yay! That makes me so happy, Karen! Thanks for popping back over to report. So glad you enjoyed it!
Hi Lindsey, do you add the spinach to the pan when ya totally frozen or do you defrost it first?
I will go in and add that – I do not thaw it first. You could, but I don’t think you need to. While we’re on the topic of spinach, I have made this several times with fresh spinach too. There tends to be a little extra liquid as the spinach cooks down, which isn’t too much of a problem.
It looks so delicious and so easy to make.
I am going to try cooking it tomorrow.
I made this Sunday night. It was delicious. My youngest son asked for seconds. I used fresh spinach.
However, my pan doesn’t look like lasagna, it looks like stacked ravioli. I’ll try to attach an Instagram photo.
Yay! I’m so glad you tried it and your son liked it too! Fresh spinach is great in this. It looks delicious!
Thanks for the recipe. Is there a way to print it out without pictures?
Leslie you can copy and paste just the text into a word document.

Thanks for this recipe! Made it tonight for my family of 6; I even snuck some extra spinach and mustard greens in there. It was great!
Looks amazing and stress-free for xmas! Going to triple for our xmas eve party! Think the baking temp/time should be adjusted?
Hi Julie! It sort of depends on they size and depth of the pan you’re using. Are you going to put a triple batch into one extra large pan? If so, then it may take a little longer to bake. If you’re doing three separate pans, then I think you should be fine with the temp and time as-is.
Am going to use very large deep foil pan. Also guessing it will take longer, just have to watch temp I guess and keep covered till the end. Happy Holidays!
Do you have any suggestions for bottled marinara sauce? I can never seem to find one that’s very good.
You know, I have had the same issue. The one I like the best right now is the organic store brand from Whole Foods. I think it says “olive oil” on the label. I hate most bottled ones because they are too sweet or have an overpowering garlic flavor. That one tends to be pretty close to my homemade sauce and it’s relatively inexpensive – less than $3 a bottle, which I also like. A close second would be the marinara from Trader Joe’s. I also don’t mind the one from Simply Organic that is available at Fred Meyer, Albertson’s, Safeway, and other Kroger stores.

Traditional lasagna is so time consuming, but this recipe was so much easier and my family loved it!
Looks amazing! Would this work with ravioli that’s not frozen but just in the fridge?
Made this recipe tonight! I’m 7mo pregnant and last night was talking about craving lasagna.
(I did substitute out spinach with ground turkey + zucchini.)
It was so easy to make and delicious! It’s going into our rotation! Love it!
Taught my g-daughter this recipe to teach her how to read a recipe and cook it. Came out delicious.
Made this last night and heating up leftovers for lunch. Whole family approved! Thank you!
Made two batches – one for my family and one for my sister, who just had a baby! We all loved it. Thank you ☺️
