Ingredients You’ll Need

Gathering the right ingredients is the secret to unlocking the magic of this Slow Cooker Baked Ziti.

The cheeses add varying textures and creaminess, and herbs bring warmth and depth. You’ll find these simple items transform into a showstopping dish with minimal fuss.

• 1 pound Italian sausage, removed from casings: This adds a deliciously savory and slightly spicy foundation to your sauce.
• 1 large onion, chopped: Provides sweetness and body, softening as it cooks to meld beautifully with the meat.
• 2 cloves garlic, minced: Garlic infuses the sauce with aromatic depth—don’t skip it!
• 1 (28 ounce) can crushed tomatoes: Offers texture and fresh tomato flavor, forming the bulk of your sauce.
• 1 (15 ounce) can tomato sauce: Adds smoothness and richness to the sauce.
• 1 (6 ounce) can tomato paste: Intensifies the tomato flavor, making the sauce luxuriously thick.
• 1 teaspoon dried oregano: Brings an earthy, slightly peppery herbal note.
• 1 teaspoon dried basil: Adds a sweet and fragrant touch that complements the tomatoes.
• 1/2 teaspoon salt: Enhances all the flavors evenly.
• 1/4 teaspoon black pepper: Adds a gentle heat and complexity.
• 1 pound ziti pasta, uncooked: This sturdy pasta holds up well in the slow cooker and soaks up sauce deliciously.
• 15 ounces ricotta cheese: Provides creamy richness that balances the tangy tomato sauce.
• 1/2 cup grated Parmesan cheese: Adds a salty, nutty kick to the cheese mixture.
• 1 large egg, lightly beaten: Helps bind the ricotta mixture for a smooth texture.
• 2 cups shredded mozzarella cheese: Melts beautifully for that gooey, cheesy topping everyone loves.
• Fresh basil leaves, for garnish (optional): Offers a fresh pop of color and herbaceous brightness when serving.

How to Make Slow Cooker Baked Ziti

Step 1: Brown the Italian Sausage

Start by heating a large skillet over medium heat and cooking the Italian sausage until it’s nicely browned. Break it up into small pieces with your spoon for even cooking. Once browned, carefully drain any excess grease to keep your dish flavorful but not greasy.

Step 2: Sauté the Onion and Garlic

Add the chopped onion to the skillet with the sausage and cook until it’s soft and translucent, which usually takes about 5 to 7 minutes. Stir in the minced garlic and let it cook for just a minute so it releases its wonderful fragrance without burning.

Step 3: Create the Sauce

Pour in the crushed tomatoes, tomato sauce, and tomato paste. Sprinkle in the dried oregano, basil, salt, and pepper, then stir everything together to combine. Bring the sauce to a gentle simmer—this simmering step is key to melding the flavors into a cohesive, deeply satisfying sauce. Reduce the heat and let it cook for about 15 to 20 minutes, stirring every now and then.

Step 4: Prepare the Cheese Mixture

In a separate bowl, whisk together the ricotta cheese, grated Parmesan, and the lightly beaten egg until smooth and creamy. This mixture adds a luscious, velvety layer that contrasts beautifully with the robust sauce.

Step 5: Assemble the Layers in the Slow Cooker

Lightly spray the inside of your slow cooker with non-stick spray to prevent sticking. Now, begin layering: start with one third of the meat sauce, then add half the uncooked ziti pasta, followed by half of the ricotta mixture spread evenly on top. Sprinkle one cup of mozzarella cheese over the ricotta. Add another third of the meat sauce, the remaining ziti, the remaining ricotta mixture, the last bit of meat sauce, and finally, the remaining mozzarella cheese on top. This layering technique ensures every bite has a perfect balance of flavors and textures.

Step 6: Slow Cook to Perfection

Cover your slow cooker and let the masterpiece cook on low for 4 to 6 hours or on high for 2 to 3 hours. The pasta will soften perfectly while absorbing those incredible flavors. If you want a slightly bubbly and browned cheese top, remove the lid during the last 30 minutes of cooking—though this step is optional, it’s certainly delightful.

Step 7: Serve and Enjoy

Carefully lift the baked ziti from the slow cooker and let it rest for a few minutes—it’s tougher to serve right off the heat. After a short wait, garnish with fresh basil leaves for a fragrant, beautiful touch before digging in.

Garnishes

Fresh basil leaves are the ultimate way to brighten up your Slow Cooker Baked Ziti with their vibrant green color and fragrant aroma.

Side Dishes

Keep it simple with a crisp green salad tossed in a light vinaigrette to cut through the richness of the baked ziti. Garlic bread or crusty Italian bread is always a welcome companion and perfect for soaking up every last bit of sauce. Roasted or steamed veggies, like broccoli or green beans, can add a fresh, healthy counterpoint to this indulgent meal.

Creative Ways to Present

For a family-style feast, serve Slow Cooker Baked Ziti directly from the slow cooker placed on the table. Alternatively, scoop portions into individual ramekins for an elegant presentation that’s perfect for dinner parties.

Make Ahead and Storage

Storing Leftovers

Slow Cooker Baked Ziti tastes just as good the next day! Store leftovers in an airtight container in the refrigerator for up to 3 to 4 days. The flavors meld even more overnight, making it perfect for easy weekday lunches or quick dinners.

Freezing

This dish freezes beautifully. After cooking, allow the baked ziti to cool completely, then portion it into freezer-safe containers or bags. It will keep well for up to 3 months. When you’re ready to enjoy it again, thaw it overnight in the refrigerator before reheating.

Reheating

Reheat refrigerated portions gently in the microwave or in a covered baking dish at 350°F (175°C) until warmed through. If reheating from frozen, defrost overnight first. To keep it from drying out, cover with foil or a microwave-safe lid and add a splash of water or sauce to maintain moisture.

FAQs

Can I use ground beef instead of Italian sausage?

Absolutely! Ground beef or even ground turkey can be substituted for a different flavor or a leaner option, though it may alter the traditional taste that the sausage brings to the Slow Cooker Baked Ziti.

Do I need to pre-cook the pasta before slow cooking?

Nope! The raw ziti pasta cooks perfectly in the sauce during the slow cooking process, soaking up all those rich flavors while softening to the ideal texture.

Can I make this vegan or vegetarian?

Yes, by swapping out the Italian sausage for plant-based sausage or sautéed mushrooms, and using dairy-free ricotta and mozzarella alternatives, you can enjoy a delicious vegan version of Slow Cooker Baked Ziti.

How thick should the sauce be before adding to the slow cooker?

The sauce should be nicely simmered and thickened after cooking with the tomatoes and seasonings—this prevents the dish from becoming too watery while slow cooking.

Why does the recipe call for removing the slow cooker lid in the last 30 minutes?

Removing the lid at the end helps the cheese on top brown slightly, creating a lovely bubbly golden crust that adds texture and visual appeal to the dish.
