Comforting Slow Cooker Baked Ziti (Printable version)

Creamy ziti pasta with ricotta, mozzarella, and Italian sausage slow-cooked in marinara sauce for an effortless family dinner.

# What you'll need:

→ Meats

01 - 1 lb Italian sausage (mild or spicy), casing removed

→ Pasta

02 - 1 lb dry ziti pasta

→ Dairy

03 - 15 oz ricotta cheese
04 - 2 cups shredded mozzarella cheese, divided
05 - 1/2 cup grated Parmesan cheese

→ Vegetables & Sauces

06 - 1 medium onion, finely chopped
07 - 3 garlic cloves, minced
08 - 48 oz marinara sauce (2 jars)
09 - 1 tablespoon olive oil

→ Seasonings

10 - 1 teaspoon dried basil
11 - 1 teaspoon dried oregano
12 - 1/2 teaspoon crushed red pepper flakes (optional)
13 - Salt and pepper to taste
14 - Fresh basil (optional, for garnish)

# Directions:

01 - Heat olive oil in a large skillet over medium heat. Sauté chopped onion until translucent, approximately 3 minutes. Add minced garlic and continue cooking for 1 additional minute until fragrant.
02 - Add crumbled Italian sausage to the skillet, breaking apart with a wooden spoon. Cook until thoroughly browned and no pink remains. Drain excess fat and set aside.
03 - In a large mixing bowl, combine ricotta cheese, half the shredded mozzarella (1 cup), grated Parmesan, dried basil, oregano, and red pepper flakes. Season generously with salt and pepper, mixing until fully incorporated.
04 - Coat the slow cooker insert thoroughly with non-stick cooking spray. Spread 1 cup of marinara sauce evenly across the bottom to prevent sticking.
05 - Arrange half the uncooked ziti pasta over the sauce base. Top with half the browned sausage, followed by half the ricotta mixture. Pour approximately 2 cups of marinara sauce over this layer.
06 - Repeat layering with remaining pasta, sausage, ricotta mixture, and marinara sauce, ensuring ingredients are evenly distributed.
07 - Sprinkle the remaining mozzarella cheese generously over the top layer.
08 - Cover and cook on LOW setting for 3 to 4 hours, until pasta reaches desired tenderness and cheese is fully melted and bubbly.
09 - Remove from heat and allow to rest for 10 to 15 minutes before serving, which helps the dish set. Garnish with fresh basil leaves if desired.

# Expert Advice:

01 -
  • The pasta cooks directly in the sauce, absorbing all those flavors while getting perfectly tender
  • Coming home to that bubbling cheese and rich tomato aroma feels like someone else did the cooking
02 -
  • Every slow cooker runs differently—start checking at 3 hours because overcooked pasta turns into mush and there's no coming back from that
  • The resting period isn't optional, otherwise you'll end up with a soupy, unstructured mess instead of distinct layers
03 -
  • Cooking the onion and sausage first develops flavors that the slow cooker can't achieve on its own
  • Check the ingredients on your marinara sauce if you're avoiding soy or nuts, since commercial sauces vary
