Slow Cooker Cheesy Spinach Lasagna

This post may include affiliate links.

Believe it or not, lasagna is a dish that actually comes out better in the slow cooker. The noodles cook perfectly, not drying out, but melding with the gooey cheese and savory ingredients to form a lasagna with slices that actually hold together nicely. The sauce and all of the flavors have time to blend and the whole dish becomes extra tasty. This is a must-try recipe, for the ease of cooking and the dependable results. Who doesn’t love a lasagna?

  • 1 tablespoon olive oil
  • 1 (5 ounce) package baby spinach or 6 cups packed baby spinach
  • 2 (24 ounce) Jars marinara sauce, no sugar added
  • 1 cup reduced fat ricotta cheese
  • 1 cup low-fat cottage cheese
  • 1 cup (part skim) mozzarella cheese
  • 1/4 cup grated parmesan cheese
  • 1 teaspoon dried oregano
  • 12 whole wheat lasagna noodles, uncooked (break in half)
  • Fresh basil for garnish


  1. Add oil to a large skillet, add spinach and cook over low heat just until wilted, about 3-5 minutes.
  2. Combine in a medium bowl ricotta cheese, cottage cheese, mozzarella cheese, and oregano.
  3. Add 1 cup marinara to the bottom of the slow cooker. Next, add a layer of broken lasagna noodles, spread 1/4 of cheese mixture over noodles, next top with 1/4 of wilted spinach. Repeat the layers until all the ingredients are used up. I prefer to add cheese last.
  4. Cover and cook until noodles are al dente and cheese is bubbly. Cook on low-heat 4-5 hours or high heat 2-3 hours. Remove the lid and add parmesan to the top. Turn off the slow cooker and allow the casserole to sit for 15 minutes before cutting. Serve garnished with fresh basil and additional parmesan, if desired.
  5. Recommend a 6 quart slow cooker, or approximately that size.

    Hello, are the lasagna noodles the ones that are meant to be boiled, or "oven-ready"?

    • SkinnyMs  December 5, 2014

      Kathleen, You can actually use either. The ones that are meant to be boiled soften up as well.

  2. Lisa  January 24, 2015

    What do you do with the two jars of marinara sauce?

    • SkinnyMs  January 26, 2015

      Lisa, To each layer you add at least a half cup to a cup of marinara sauce, and add remaining marinara sauce to the top of the lasagna to cover.

    Will gluten free noodles work

    • SkinnyMs  January 26, 2015

      Anne, Yes gluten-free noodles will work well.

  4. SWeiss  January 4, 2016

    We loved this recipe. My kids helped me make it and they loved it too. Will make again.

  5. Mrs. Allen  January 12, 2016

    Mine tastes kind of plain is it supposed to be like that?

    • SkinnyMs.  January 13, 2016

      If you are new to clean eating, you may find that your taste buds need a little time to adjust to the missing processed sugars and other ingredients. If you still prefer to add a little zip to your recipes, feel free to up the spices. A little extra garlic can go a long way. 🙂

    is this a clean eating recipe

      Yes, all of our recipes are clean recipes.

    Is it necessary to wilt the spinach? Won’t it wilt as it cooks?

    • Nichole  October 16, 2016

      Great question, Sheila!

      Yes, it is necessary to wilt the spinach. As spinach cooks it releases water, if it is not wilted before added to the slow cooker the lasagna will end up very soupy!

      • Sheila  October 19, 2016

        Tried the lasagna yesterday. It was great, and so easy! Everyone in the family loved it. Thanks!

        • Kym Votruba  October 19, 2016

          Great! Thanks for sharing!

  9. ross  December 19, 2016

    Do you mean 12 oz of lasagna noodles or 12 packets or lasagna?

    • Nichole Furlong  December 19, 2016

      Hi Ross – the recipe says “12 whole noodles”. So 12 individual noodles.

  10. Jan  January 10, 2017

    What other noodle can i use.

  11. Pam  March 25, 2017

    Hi, how long do you cook it in the slow cooker and low or high temp?

    • Gale Compton  March 25, 2017

      Pam, Cook on low-heat 4-5 hours or high heat 2-3 hours. Remove the lid and add parmesan to the top. Turn off the slow cooker and allow the casserole to sit for 15 minutes before cutting. Serve garnished with fresh basil and additional parmesan, if desired.

  12. Jennifer  June 30, 2017

    Do you have to use cottage cheese?

    • Nichole Furlong  July 1, 2017

      Hi Jennifer, great question! You do not need to use cottage cheese. Instead, increase the ricotta to 2 cups.

  13. Colette Huntoon  October 4, 2017

    Can I use frozen spinach? I will be making my own sauce and adding green pepper,red pepper,onion and mushrooms. I also want to add meat I want to do a lean sausage and burger combination what do you think would work well?

    • Gale Compton  October 5, 2017

      Colette, I like your sausage burger combination idea. You can use frozen spinach, just be sure to sqeeze out as much liquid as possible. We love
      fresh vs. frozen spinach, but that’s our preference. Keep us posted. 🙂

  14. Nancy White  October 10, 2017

    This sounds delicious but I am cooking for only two of us. Can I change the ingredients and use a smaller slower cooker or is it possible to make this on the stovetop?

    • Gale Compton  October 11, 2017

      Nancy, Definitely! Yes, you can make this on the stovetop or in the oven. 🙂

      • Jean Hale  January 21, 2018

        How long could I do this in the oven (love using the crockpot but it’s on the blink now!), so as an alternative, what temperature and time would I cook this in the oven? Thanks! Love all of your recipes, BTW! Especially meatless ones! Or seafood!

        • Gale Compton  January 22, 2018

          Jean, I highly recommend my Skinny Lasagna Rolls, baked in the oven. It’s easy to make and delicious.

          In 2018, we’ll have plenty of meatless recipes, all delicious. So happy you’re enjoying our recipes. 🙂

  15. Joyce  October 10, 2017

    Very easy to cook. My husband prefers the meat lasagne so I now have a meal I can eat on another day.

  16. Rosa Romero  October 15, 2017

    Would like to make this with zucchini as the noodles. Can I replace the noodles with the zucchini?

    • Gale Compton  October 15, 2017

      Rosa, Keep in mind the zucchini noodles only take a few minutes to cook. I would recommend making this recipe on top of the stove. 🙂

  17. Cyrisse  January 27, 2018

    What percentage of low fat cottage cheese should be used ? One or two percent?

    • Gale Compton  January 27, 2018

      Cyrisse, It’s up to you, but we used 1%. 🙂

  18. Veronica  October 1, 2018

    This is my favorite recipe! I’ve made it 3-4 times and my family LOVES it as well!
