Growing up, lasagna was ALWAYS my favorite dish and what I requested on special occasions. It’s really a shame that I don’t have a SINGLE lasagna recipe on my blog but I’m very happy that I’m here to fix that today! AND I’m excited to team up with The Crock-Pot brand once again to bring you this simple and delicious vegetarian recipe!

I used the 7-Qt. Cook & Carry™ Easy Clean Slow Cooker for this recipe which is perfect because it’s large enough for an average sized lasagna. I also love the fact that you can easily carry this slow cooker around. This particular recipe would be perfect for potlucks and work get togethers.

You can go ahead and assemble everything but then wait to cook it until you’re at your destination. OR you can cook everything and simple carry the entire slow cooker to a party and then just turn it to the “keep warm” setting.

If you’re in the market for a new slow cooker, I HIGHLY recommend the 7-Qt. Cook & Carry™ Easy Clean Slow Cooker. You can pick up the slow cooker at target HERE!

How to make this Vegetarian Crockpot Lasagna

To make the lasagna, star out by sautéing your veggies. You want to get them a little softened before they go into the slow cooker. The marinara sauce and tomato sauce will also get mixed in to create a super delicious veggies sauce!

Next mix together the ricotta, mozzarella, Italian seasoning, and spinach.

Now it’s time for assembly. Start by spreading a little bit of sauce on the bottom of the slow cooker. Then layer the lasagna up by placing in several lasagna noodles followed by 1/3 of the ricotta mixture and more of the sauce. Repeat until everything is used up and then cook on high for 1 1/2 hours. Sprinkle on more mozzarella cheese (if using) and cook for an additional 30 minutes.

And that’s it! Super easy and so ridiculously delicious! Of course, you can make simple modifications to this recipe as needed and add in/ take out any of the veggies desired.

I hope that your family loves this recipe as much as mine did! If you make it, please remember to snap a picture and share it with me on Instagram @foodwithfeeeling !

Ingredients 

  • 1 ½ pounds baby bella mushrooms, roughly chopped
  • ½ teaspoon salt
  • 1 tablespoon olive oil
  • 1 cup onion, heaping cup, finely diced
  • 2 carrots, large, finely diced
  • 24 ounces spaghetti sauce, divided
  • 15 ounce tomato sauce
  • 2 10-ounce boxes frozen chopped spinach, thawed and squeezed of excess moisture
  • 15 ounces ricotta cheese, can sub for vegan ricotta cheese
  • 1 teaspoon Italian seasoning
  • 2 ½ cups shredded mozzarella cheese, divided (sub for vegan shredded as desired or leave it out completely)
  • 8-10 lasagna noodles

Instructions 

  • In the bottom of your slow cooker, evenly spread 2/3 cup of the spaghetti sauce. Turn to high heat.
  • Heat a large skillet over medium heat and add in the mushrooms and stir in the salt. Cook for about 5 minutes, stirring often until the mushrooms begin to release moisture. Continue to cook until most of the moisture is gone.
  • Add in the olive oil, onions, and carrots. Continue to cook until the carrots just begin to soften. Stir in the spaghetti sauce and the tomato sauce. Remove from heat.
  • In a medium bowl, mix together the ricotta, 1 1/2 cups of the mozzarella, italian seasoning, and spinach.
  • Layer your lasagna: on top of the initial layer of sauce, place 2 lasagna noodles in the middle. Break a 3rd noodle in half and put it on the sides to fill in the gaps. It doesn’t need to be perfect for completely covered. Noodles come in different sizes so adjust the recipe to fit your noodles as needed.
  • Finish the layering by spreading out 1/3 of the ricotta mixture, 1 cup of the veggie sauce, 2-3 more noodles, 1/3 of the ricotta mixture, 1 cup of sauce, 2-3 more noodles, remaining ricotta, and remaining sauce. Cook on high for 1 1/2 hours.
  • Add on the remaining cup of mozzarella cheese and cook on high for 30 more minutes.
  • Serve and ENJOY!

    Amazing recipe!  So delicious.  Needed to “use up” some lasagna noodles I had, so cooked this.  Not fond of mushrooms, so cooked diced red bell pepper with the onion mixture.  Used only 1 package of spinach.  Portion sizes were very generous and fit right in with my current weight loss regime.  Will definitely use this recipe for the noodles I still have.

  2. Ashley says:

    Have you ever made this in the oven? Curious the cooking difference

    1. Brita says:

      I actually haven’t tried this particular recipe in the oven but it should work fine. I’d bake it covered at 350 for 20 minutes, uncovered and then bake an additional 25 minutes

  3. Miss Victoria says:

    Do you cook the noodles first?

    1. Brita says:

      no! :)

  4. Christine Vanwijn says:

    Hi – Going to try this tomorrow! Are regular lasagna noodles ok to use or do they need to be special no-boil? Thanks.

    1. Brita says:

      I just used regular (NOT the no boil ones)

  6. robin says:

    do u use the regular lasagna noodles or the ones that require no boiling?

    1. Linda Schoonover says:

      IMO…Regular noodles cook as well as no-cook noodles just as long as they’re covered with sauce/liquid. I bake my lasagna with regular noodles.

    Added 1 can garbanzo beans. Gave the meal great texture.

    Tried this out for a second time, because it was so amazing the first! Unfortunately, my mushrooms were spoiled so I substituted broccoli and it was just as great!! 

  9. Natasha says:

    Not sure if I missed it somewhere, but are you using regular lasagna noodles or no-boil noodles in this recipe?

    1. Jennifer says:

      I would love to know the answer to this question, as well! I have a new crock pot arriving tomorrow and I’d love to break it in with this recipe. ?

  10. Ann says:

    Oh my goodness, these lasagna looks absolutely amazing! That is a dish that would please my entire family. I never used mushrooms in lasagna before! And I love all the vegetable goodness! Can you advise if it can be frozen as I will need to make it in advance?

    1. Brita says:

      I’ve never tried freezing this lasagna but I’m sure that it would work well as this is something that people often do with lasagnas! I hope that you like it!
