- Ricotta Cheese: Creamy and luscious, ricotta adds a luxurious texture that pairs perfectly with the other ingredients. We like to use this vegan ricotta from Kite-Hill.
- Egg: This binding agent helps to hold the spinach and ricotta mixture together, contributing to the lasagna’s structure. You can sub with a flax-egg or egg substitute of choice if needed.
- Parmesan Cheese: The nutty and savory notes of Parmesan elevate the flavors and add a delightful umami depth. We like Miyokos or Violife for dairy-free

- Lasagna Noodles: Essential for creating those signature layers, choose regular, gluten-free, or grain-free options based on your preference.

Instructions: How to make Crock Pot Lasagna
- Prepare the Spinach-Ricotta Mixture: In a large bowl, combine the chopped fresh spinach, ricotta cheese, egg, dried parsley, and a portion of the grated Parmesan cheese. Mix until all the ingredients are well blended. Set this mixture aside.
- Create the Flavorful Marinara Sauce: In another bowl, whisk together the marinara sauce, water, tomato paste, Italian seasoning, garlic powder, and crushed red pepper flakes. This sauce will infuse your lasagna with rich flavors.
- Layer the Crock Pot: Begin by spooning a layer of the marinara sauce mixture onto the bottom of a large oval slow cooker. Spread it into a thin, even layer.
- Build the Layers: Place three uncooked lasagna noodles on top of the sauce layer. You may need to break a noodle into pieces to ensure most of the gaps are covered. Now, dollop a quarter of the spinach-ricotta mixture in small spoonfuls over the noodles. Gently spread it out to create an even layer.
- Add the Sauce and Cheese: Spread about 1½ cups of the marinara sauce over the spinach-ricotta layer. Sprinkle this layer with shredded mozzarella cheese and a portion of the remaining grated Parmesan cheese.
- Repeat the Layers: Repeat the layering process, starting with the uncooked noodles and ending with the mozzarella and Parmesan topping. This will create a beautiful lasagna stack.
- Slow Cook to Perfection: Cover the slow cooker and set it to cook on low heat. Allow the lasagna to cook for around 3½ to 4 hours. During this time, the noodles will become tender and the flavors will meld together deliciously.
- Rest and Serve: Once the cooking time is complete, turn off the slow cooker. Let the lasagna rest for about 30 minutes before slicing and serving. This resting period allows the flavors to settle and makes for easier slicing.

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!
So Un -
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.
