Spinach and ricotta cheese come together in this vegetarian-friendly slow cooker lasagna. The best part? You can carefully place your ingredients directly in the crockpot and then forget about this dish for three and a half hours—which is the ideal timeline for a large Sunday gathering.

Layers of marinara sauce, pasta, mozzarella, and a spinach-ricotta mixture cook slowly until the ingredients meld and the noodles become tender. Pair with a simple romaine salad, and you have a classic Italian staple with just 15 minutes of hands-on time.



  • 2 10-ounce packages chopped frozen spinach, thawed and squeezed to remove excess moisture

  • 1 cup ricotta

  • ¾ cup grated Parmesan (3 ounces)

  • 3 cups marinara sauce

  • 6 regular lasagna noodles (not no-boil)

  • 1 ½ cups grated mozzarella (6 ounces)

Romaine Salad

  • 1 small head romaine lettuce, cut into strips (about 8 cups)

  • 1 cucumber, thinly sliced

  • ½ small red onion, thinly sliced

  • kosher salt and black pepper

  • 2 teaspoons red wine vinegar

  • 2 tablespoons olive oil


  1. In a bowl, mix together the spinach, ricotta, and ½ cup of the Parmesan. In a second bowl, mix together the marinara sauce and ½ cup water.

  2. Spread ¾ cup of the marinara mixture in the bottom of a 4- to 6-quart slow cooker.

  3. Top with 2 noodles (breaking to fit), ¾ cup of the remaining marinara mixture, half the spinach mixture, and ½ cup of the mozzarella; repeat.

  4. Top with the remaining noodles, marinara mixture, mozzarella, and Parmesan.

  5. Cover and cook on low until the noodles are tender, 3½ to 4 hours.

  6. In a large bowl, whisk together the oil, vinegar, ½ teaspoon salt, and ¼ teaspoon pepper. Add the lettuce, cucumber, and onion and toss to combine. Serve with the lasagna.
