How to Make Slow Cooker Baked Ziti
Start by spraying your slow cooker with non-stick cooking spray. In a large bowl, mix together the ricotta, 1½ cups mozzarella, Parmesan, egg, basil, salt, and pepper until well combined.
Add the uncooked ziti pasta directly to the slow cooker. Pour in the marinara sauce, water, and minced garlic, stirring gently to coat the pasta. Dollop spoonfuls of the cheese mixture over the pasta and gently fold it in—don’t overmix, you want pockets of cheese throughout.
Cover and cook on low for 3-4 hours or on high for 1½-2 hours, until the pasta is tender. About 15 minutes before serving, sprinkle the remaining ½ cup mozzarella on top, cover, and let it melt. Let it rest for 10 minutes before serving.

Recipe Tips & Variations
Don’t lift the lid during cooking—this releases heat and adds time to your cook time. The pasta absorbs liquid as it cooks, so if it looks a bit soupy at first, don’t worry, it will thicken up.
Make it heartier: Brown 1 pound of Italian sausage or ground beef and add it in with the sauce for a protein-packed version.
Add veggies: Stir in fresh spinach, diced bell peppers, or mushrooms during the last 30 minutes of cooking.
Cheese swaps: Try using cottage cheese instead of ricotta, or add a layer of provolone for extra flavor.
Storage: Leftovers keep in an airtight container in the fridge for up to 4 days and reheat beautifully in the microwave.
Serving Suggestions
This slow cooker baked ziti is a complete meal on its own, but pairs wonderfully with a crisp green salad and garlic bread for soaking up extra sauce. A simple Caesar salad or caprese salad adds freshness to balance the richness.
For gatherings, serve it straight from the slow cooker to keep it warm throughout your meal. It’s also perfect for potlucks since it travels well and stays hot for hours.
Add a sprinkle of fresh basil, extra Parmesan, or a drizzle of olive oil just before serving for a restaurant-quality finish.
Frequently Asked Questions
Can I use a different type of pasta?
Yes! Penne, rigatoni, or mostaccioli work perfectly in this recipe. Just avoid long pasta like spaghetti or fettuccine, as shorter tube-shaped pasta works best in the slow cooker and holds the sauce better.
Do I really not need to cook the pasta first?
Absolutely not! The pasta cooks directly in the sauce, absorbing all that flavor while becoming perfectly tender. The water added to the sauce provides enough liquid for the pasta to cook through completely in 3-4 hours on low.
Can I make this ahead of time?
Yes, you can assemble everything in your slow cooker insert the night before, cover, and refrigerate. In the morning, just place the insert in the slow cooker and add 30 minutes to the cook time since you’re starting with cold ingredients.
