Slow Cooker Lasagna – makes the perfect easy comforting meatless meal. Best of all, this entire recipe cooks up all in the crock-pot! Now with a step-by-step video!
One of the best parts about food blogging for me is definitely the amazing people that you get to “meet” along the way.
Samantha is the sweetheart over at Five Heart Home where she shares healthy and delicious meals that are quick and easy to make along with fun free printables.
She’s a busy mom of three beautiful kiddos and is super talented and creative. She also just finished writing her first cookbook, Real Food Slow Cooker Suppers that was released yesterday!
I couldn’t be more excited and proud of her because writing a cookbook with small kids and keeping up with a blog along with all those other family responsibilities is seriously no easy task.
Her book is just beautiful and full of 80 delicious slow cooker dinner recipes that call for all real, fresh, unprocessed ingredients.
I loved the variety of cuisines featured and that there was a gorgeous color photo for every single recipe.
This Slow Cooker Lasagna is just one of the awesome dishes you will find in there. Easy crock-pot recipes are my favorite and I loved that this entire recipe was cooked in the slow cooker!
It’s the perfect meal for Meatless Monday and full of gooey layers of cheese and yummy greens in every bite.
I adapted the recipe slightly with what I have and to suit my families tastes and have listed those in the recipe below. Instead of just frozen spinach, I used a mix fresh spinach and kale.
This Slow Cooker Lasagna was seriously SO delicious and a big hit with my family!
Even my hubs who is a big meat-eater couldn’t get enough so you can bet this lasagna will be showing up regularly around here again.

Slow Cooker Lasagna - makes the perfect easy comforting meatless meal. Best of all, this entire recipe cooks up all in the crock-pot! Now with a step-by-step video!
- 3-4 cups fresh chopped spinach and chopped kale stems removed, boiled and drained (can also use 3 (10 ounces) boxes of frozen spinach)
- 1 15-ounce container ricotta cheese
- 1 large egg room temperature
- 1 teaspoon dried parsley
- 1 -/4 cups freshly grated Parmesan cheese divided
- 2 24-ounce jar marina sauce or 6 cups homemade sauce
- 1/2 cup water
- 3 Tablespoon tomato paste
- 1 Tablespoon Italian seasoning I used 1 teaspoon each of dried rosemary, oregano, thyme and basil instead
- 1/2 teaspoon garlic powder
- 1/4 teaspoon crushed red pepper flakes
- 12 uncooked lasagna noodles do not use no boil noodles
- 4 cups shredded mozzarella cheese
- fresh basil and parsley chiffonade; for serving
In a large bowl, combine the spinach, ricotta, egg, parsley and 3/4 cup of the Parmesan until well blended and set aside. In another large bowl, combine the marina sauce, water, tomato paste, Italian seasoning, garlic powder, and crushed red pepper flakes and set aside.
Spoon 1/2 cup of the sauce into the bottom of a large oval slow cooker and spread it into a thin layer. Place 3 lasagna noodles on top of the sauce, breaking a noodle into pieces (if necessary) in order to cover most of the blank spaces. Dollop 1/4 of the spinach-ricotta mixture into small spoonfuls on top of the noodles and gently spread it into an even layer. Spread 1-1/2 cups marinara sauce on top of the spinach-ricotta mixture. Sprinkle the top of this layer with 1 cup of the shredded mozzarella and 2 tablespoons of the remaining grated Parmesan.
Repeat these layers more times, starting with the noodles and ending with the mozzarella and Parmesan topping. Cover the slow cooker and cook on low for 3-1/2 to 4 hours, until the noodles are tender but not overcooked. Turn off the slow cooker and allow the lasagna to rest for 30 minutes before slicing and serving.

HI Kelly. Going to try the recipe this weekend. Can I use all fresh spinach instead of frozen and, if so, how much? Thanks.
Kelly -
Hi Debbie, yes, you can use all fresh spinach which I prefer to do as well. You can use as much as 2lbs (about 20 cups) of fresh spinach. Just saute or boil (and drain) until just wilted. Good luck, hope you enjoy!

Do I need to add the 1/2cup of water to the marinara sauce and the additional tomato paste? I am going to be using my homemade bolognese sauce and I am afraid it might water down the sauce and add too much acidity by adding extra tomato paste.
Kelly -
Hi So Un, yes, the and tomato paste are in addition to the marinara sauce. If your homemade sauce is more on the watery side, feel free to use a little bit less water or leave it out if you think it will water it down. The tomato paste adds additional flavor so I would say to use it as well. Good luck and hope it works out!
Jeri Stadnicki -
Do you cook the spinach first or just thaw before adding to the cheese mixture?
Kelly -
I just thaw it before adding it to the cheese.
