  • 1 carton (15 ounces) part-skim ricotta cheese
  • 1 package (10 ounces) frozen chopped spinach, thawed and squeezed dry
  • 2-1/2 cups shredded Italian cheese blend
  • 1/2 cup diced red onion
  • 1/2 teaspoon garlic powder
  • 2 teaspoons dried basil
  • 1/2 teaspoon dried oregano
  • 1/2 teaspoon dried thyme
  • 2 jars (24 ounces each) roasted garlic Parmesan pasta sauce
  • 2 cups water
  • 1 package (12 ounces) jumbo pasta shells
  • Optional: Additional shredded Italian cheese blend and sliced fresh basil


  1. Mix first 8 ingredients (mixture will be stiff). In a greased 6-qt. slow cooker, mix 1 jar pasta sauce with water. Fill shells with ricotta mixture; layer in slow cooker. Top with remaining jar of pasta sauce.
  2. Cook, covered, on low until pasta is tender, 4-5 hours. If desired, serve with additional cheese and fresh basil.
Health Tip: Relative to other cheeses, ricotta is especially high in calcium. Just 1/4 cup provides almost 20 percent of the recommended daily intake.
