Slow Cooker Vegetarian Lasagna

In college, choosing macaroni and cheese or juniorettes is always a first choice- But sometimes, it just doesn't cut it. Home cooked meals are very necessary every once in awhile, as you may know. Slow cooker recipes are great in apartments, especially when space is limited to prepare a feast. This takes only minutes to prepare, then let it cook while you study or rest for 2 1/2 hours. *Note: Veggie crumbles are a heat and serve vegetarian meat substitute- If you don't want this to be vegetarian, you can substitute 8 ounces ground beef, browned, for the crumbles.

Ingredients Nutrition


  1. In medium bowl, combine marinara sauce and tomatoes with their juice.
  2. Spray 4.5-6 quart slow cooker bowl with nonstick cooking spray.
  3. Spoon 1 cup tomato-sauce mixture into bowl.
  4. Arrange 1/4 of noodles over sauce, overlapping noodles and breaking into large pieces to cover as much sauce as possible.
  5. Spoon about 3/4 cup sauce over noodles, then top with 1/2 cup ricotta, and 1/2 cup shredded cheese.
  6. Spread half of spinach over cheese.
  7. Repeat layering 2 more times beginning with noodles, but in middle layer, replace spinach with frozen crumbles. Place remaining noodles over spinach, then top with remaining sauce and shredded cheese.
  8. Cover slow cooker with lid and cook on low 2.5 to 3 hours or on high 1.5 to 1.75 hours, or until noodles are very tender.

Thank you! Using the diced tomatoes and spinach, and the veggie crumbles, in the sauce is a great idea! I also added mushrooms to mine. Instead of exchanging the layers as recommeded here, I put it all together in the sauce. Thanks for the Prego idea--I used Roasted Red Pepper and Garlic, which was a hit. I used regular lasagne noodles--they always come out right in my crockpot lasagne. I also add parmesan cheese and green onions to my cottage cheese (instead of ricotta.) Will use again!

This is a great recipe as it is so simple, and you can play around with it to suit your taste! I added mushrooms and sweet peppers. The only thing I will try differently next time is add a can of Rotel and try cream cheese in place of ricotta. Thanks!
