Even though this Slow Cooker Baked Ziti Recipe feels indulgent, the ingredient list is refreshingly simple. Each component plays a crucial role, from the robust ground beef that adds savory depth to the tender pasta soaking up all the saucy goodness.

1 pound ground beef: Provides a rich, meaty base for the sauce, delivering hearty flavor.
1 onion (finely chopped): Adds natural sweetness and a gentle bite that softens during cooking.
2 cloves garlic (finely minced): Brings aromatic warmth that infuses the entire dish deeply.
1½ teaspoons salt: Essential for enhancing all the flavors perfectly.
1 teaspoon dried basil: Offers a classic herbaceous note to brighten the sauce.
1 teaspoon dried parsley: Delivers a fresh, subtle earthiness and vibrant color.
1 can diced tomatoes (28oz or 798ml) with liquid: Adds a sweet, slightly chunky texture for a robust tomato base.
2½ cups marinara sauce: Thickens the sauce and brings layers of tomato richness.
2½ cups low-sodium chicken broth: Keeps the sauce moist and adds gentle savory depth without overpowering.
4 cups dry penne or ziti pasta (340g): The perfect pasta shape that holds sauce in every bite.
2 cups shredded mozzarella cheese: Melts into gooey, golden goodness that crowns the dish.

How to Make Slow Cooker Baked Ziti Recipe

Step 1: Brown the Beef and Onion

Start by heating a large skillet over medium-high heat. Add the ground beef and finely chopped onion, cooking together until nicely browned and fragrant, about 5 minutes. This step builds the foundational savory flavor that will carry through the whole dish.

Step 2: Incorporate Garlic and Herbs

Next, stir in the minced garlic, salt, dried basil, and parsley. Cook everything together for just one minute until the garlic releases its aroma, taking care not to let it burn. This quick sauté infuses the mixture with bright herb notes while layering flavor complexities.

Step 3: Combine Ingredients in Slow Cooker

Transfer the beef and onion mixture into your slow cooker. Add the diced tomatoes with their juices, marinara sauce, and chicken broth. Stir everything well, ensuring all ingredients are thoroughly mixed and ready to develop their magic during the slow cooking process.

Step 4: Slow Cook the Sauce

Cover the slow cooker and cook on low for 6 hours, or if you’re short on time, set it to high for 3 hours. This slow simmer allows the flavors to gently marry, the tomatoes to soften, and the sauce to develop a depth that is impossible to achieve with quick cooking.

Step 5: Add Pasta and Cook Until Tender

Turn the slow cooker temperature to high, then stir in the uncooked pasta until it’s well coated in the sauce. Cover again and let it cook for 15 to 30 minutes, checking and stirring at the 15-minute mark. The pasta finishes cooking by absorbing the delicious sauce, becoming perfectly al dente by the time it’s done.

Step 6: Top with Cheese and Melt

Once the pasta is tender, remove the lid and generously sprinkle shredded mozzarella cheese on top. Cover the slow cooker again and let it sit for 3 to 5 minutes off heat, allowing the cheese to melt into a luscious, gooey blanket that brings the whole dish together.

Creative Ways to Present

Serve this dish straight from the slow cooker for a casual, comforting family-style meal. Or, for something special, portion it into individual ramekins, broil the mozzarella until bubbly and golden, and garnish each with a basil leaf—instantly turning a humble meal into an inviting presentation.

Make Ahead and Storage

Storing Leftovers

Leftover Slow Cooker Baked Ziti Recipe can be stored in an airtight container in the refrigerator for up to 3 days. Make sure the dish has cooled to room temperature before refrigerating to keep the texture of the pasta and sauce intact.

Freezing

This recipe freezes wonderfully. Simply portion it into freezer-safe containers and freeze for up to 2 months. When you’re ready to enjoy, thaw overnight in the fridge to preserve the rich flavors and creamy texture.

Reheating

Reheat leftovers in the microwave or in a covered dish in the oven at 350°F (175°C). Adding a splash of water or broth before reheating helps keep the pasta moister and prevents it from drying out. Stir halfway through heating for even warmth.

FAQs

Can I use turkey or chicken instead of beef?

What if I don’t have marinara sauce on hand?
