This vegetarian lasagna couldn't be easier, thanks to jarred pasta sauce and no-boil lasagna noodles. Prep it in the morning and let your crock pot do the work.

Ingredient Checklist


Instructions Checklist
  • Combine bell pepper, mushrooms, and spinach in a medium bowl. Combine pasta sauce, tomatoes, ricotta, and 1/2 cup Parmesan in a large bowl.

  • Spread 1 cup of the sauce mixture in a 6-qt. slow cooker. Place 3 noodles over the sauce, breaking them as needed to fit in one layer. Spread another 1 cup sauce over the pasta. Layer on one-third of the vegetable mixture, 3 more noodles, and 1 cup sauce. Sprinkle with 1/2 cup mozzarella. Continue layering one-third of the vegetables, 1 cup sauce, 1/2 cup mozzarella, and the remaining noodles. Top with a final layer of the remaining vegetables, the remaining sauce, and the remaining 1 cup mozzarella.

  • Cover and cook on Low for 5 hours.

  • Turn off and unplug the slow cooker. Let the lasagna stand, covered, for 1 hour (see Tip). Serve topped with the remaining 1/4 cup Parmesan and basil.


Tip: To prevent condensation building up on the underside of the lid during the 1-hour rest time, place a paper towel under the lid during the rest time.

Equipment: 6-qt. slow cooker

Would this be considered "vegetarian" considering it contains Parmesan and Mozzarella cheese? If not what would be a good substitute? Read More

Really easy & good! My family who likes meat kind of missed the meat a bit but I liked the veggie flavor. I ended up cooking a bit less than the 5 & 1 hours. Put on 8 hour low setting for first 3-4 hrs. Read More

It is considered vegetarian but not vegan. A good sub in would be vegan cheese for the mozzarella and nutritional yeast for the parm. Read More
