We were surprised by how well lasagna cooks up in the slow cooker. Use traditional noodles, and place them in the cooker uncooked. We tried specially formulated no-bake noodles, and they didn't work well.

Ingredients

  • 9 ounces part-skim ricotta cheese
  • 1 ounce Asiago cheese, grated and divided (about ¼ cup)
  • 2 tablespoons chopped fresh flat-leaf parsley, divided
  • 2 tablespoons chopped fresh chives, divided
  • 1/4 teaspoon freshly ground black pepper
  • 6 garlic cloves, divided
  • 6 cups water
  • 1/2 cup red wine vinegar
  • 1 large yellow crookneck squash, cut into ¼-inch-thick slices
  • 1 large zucchini, cut into ¼-inch-thick slices
  • Cooking Spray
  • 8 ounces hot Italian pork sausage links, casings removed
  • 2 cups chopped onion
  • 1 tablespoon olive oil
  • 3 (3.5-oz.) packages shiitake mushrooms, stemmed and sliced
  • 1 cup unsalted chicken stock (such as Swanson)
  • 1/2 cup chopped fresh basil leaves
  • 1 (25-oz.) jar lower-sodium marinara sauce (such as Dell'Amore)
  • 12 uncooked lasagna noodles
  • 3 ounces fontina cheese, shredded and divided (about ¾ cup)
