Slow Cooker Baked Ziti (Printable)

Creamy, cheesy pasta dish with Italian sausage that cooks effortlessly in your slow cooker.

# 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
13 - Salt and black pepper to taste
14 - Fresh basil for garnish

# How To Make It:

01 - Heat olive oil in a large skillet over medium heat. Sauté chopped onion until translucent, approximately 3 minutes. Add minced garlic and cook for 1 minute until fragrant.
02 - Add Italian sausage to the skillet, breaking apart with a wooden spoon. Cook until thoroughly browned and no longer pink. Drain excess fat and set aside.
03 - In a large mixing bowl, combine ricotta cheese, half the mozzarella (1 cup), Parmesan, dried basil, oregano, and red pepper flakes. Season generously with salt and pepper. Mix until evenly 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 - Add half the uncooked ziti pasta, followed by half the browned sausage, half the ricotta mixture, and approximately 2 cups of marinara sauce. Repeat layers with remaining pasta, sausage, ricotta, and sauce.
06 - Sprinkle the remaining mozzarella cheese evenly over the top layer.
07 - Cover and cook on LOW setting for 3 to 4 hours, until pasta is tender and cheese is melted and bubbly.
08 - Remove lid and let rest for 10 to 15 minutes to set. Garnish with fresh basil leaves before serving.

# Expert Advice:

01 -
  • The ricotta layer stays impossibly creamy instead of drying out like it sometimes does in the oven
  • You can assemble it in the morning and forget about it until dinner time
02 -
  • Every slow cooker runs differently, so check at 3 hours to prevent mushy pasta
  • The resting period is not optional—it needs time to firm up or you'll have a delicious mess on your plate
03 -
  • Mix an egg into the ricotta for an extra creamy layer that holds together better
  • Check your marinara sauce label if you're avoiding soy or nuts
