All it takes is layering ingredients into your crockpot and letting the magic happen.

Whether you’re feeding a crowd, meal prepping for the week, or just want a one-dish dinner with minimal cleanup, this is your new go-to.


Why I Love This Recipe

As someone who lives for cozy, crave-worthy dinners that require almost zero effort, I fell in love with this no-boil baked ziti the moment I tried it. The pasta cooks right in the sauce, absorbing flavor and reaching the perfect tender texture without turning mushy.

This dish is especially great because:

  • It’s a true dump-and-go meal.
  • There’s no need to boil or drain pasta.
  • It’s ultra cheesy and completely satisfying.
  • The leftovers (if you have any) reheat beautifully.

Ingredients

  • 1 pound uncooked ziti or penne pasta
  • 3 cups marinara sauce (use your favorite jarred or homemade)
  • 1 cup water or low-sodium chicken broth
  • 1 cup ricotta cheese
  • 2 cups shredded mozzarella cheese
  • ½ cup grated Parmesan cheese
  • 1 egg (optional, helps bind ricotta)
  • 1 teaspoon Italian seasoning
  • 1 teaspoon garlic powder
  • Salt and pepper to taste
  • Fresh basil or parsley (for garnish, optional)

Swaps & Notes

  • No ricotta? Use cottage cheese or a mix of cream cheese and sour cream.
  • Want meat? Brown 1 lb of ground beef, sausage, or turkey and layer it in.
  • Gluten-free? Use a certified GF pasta, but reduce liquid slightly and monitor doneness.
  • Extra veggies? Add chopped spinach, zucchini, or mushrooms in layers.

Instructions

  1. Mix the ricotta layer
    In a bowl, combine ricotta, egg (if using), garlic powder, Italian seasoning, salt, pepper, and ¼ cup Parmesan. Set aside.
  2. Grease your slow cooker
    Spray the inside with cooking spray to prevent sticking.
  3. Layer the ingredients
    • Start with 1 cup of marinara sauce on the bottom.
    • Add half the uncooked ziti.
    • Dollop half the ricotta mixture.
    • Sprinkle 1 cup mozzarella.
    • Repeat: sauce → pasta → ricotta → mozzarella.
    • Pour remaining sauce and water/broth evenly over the top.
    • Sprinkle the rest of the Parmesan.
  4. Cook
    • Cover and cook on LOW for 3½ to 4½ hours, or until pasta is tender.
    • Avoid lifting the lid too often—trust the process!
  5. Finish
    • Optional: Add more mozzarella in the last 10 minutes, cover until melted.
    • Garnish with fresh basil or parsley before serving.

Tips for Success

  • Use regular (not oven-ready) pasta for best results.
  • If the sauce is very thick, add an extra splash of water.
  • Resist the urge to stir mid-cooking. It cooks more evenly layered.
