  • 15 ounce low-fat ricotta cheese
  • 4 cups low-fat mozzarella cheese shredded, divided in half
  • 1 egg beaten
  • 1-2 garlic cloves minced
  • 1 cup carrots sliced thin
  • 1 medium zucchini sliced about ¼ inch thick and cubed (about 2 cups)
  • 8 ounces mushrooms sliced (about 2 cups)
  • ½ cup red onion sliced thin
  • 12 whole wheat lasagna noodles
  • 48 ounces pasta sauce
  • ¼ cup Parmesan cheese grated


  • Combine ricotta, 2 cups of mozzarella cheese, egg and garlic in a bowl and set aside.
  • Generously coat the inside of the crock pot with cooking spray.
  • Spread ½ cup of pasta sauce over the bottom of the crock pot.
  • Layer 3 lasagna noodles in the bottom of the crock pot, breaking noodles as necessary and overlapping pieces to cover the pasta sauce. Don't worry how it looks!
  • Cover noodles with a third of the cheese mixture. (Tip: drop cheese mixture in Tablespoon size heaps and use finger tips to gently spread the cheese mixture evenly over the noodles.)
  • Layer a third of the vegetable mixture (about 1 ½ cups) over cheese mixture.
  • Spread ¾ cup of pasta sauce over the vegetables.
  • Repeat steps 4 through 7 two more times
  • Top with 3 more broken lasagna noodles and remaining pasta sauce.
  • Cook on low heat for 4 hours.
  • Remove lid and sprinkle 2 cups of mozzarella cheese and ¼ cup of Parmesan cheese over the top.
  • Replace lid and allow to sit for about 30 minutes so cheese will melt and lasagna will set.
  • Serve from crock-pot.
