How To Make Slow-Cooker Baked Ziti

Step 1: Prepare The Meat Sauce

Heat a large skillet over medium heat.

Add:

Ground beef or Italian sausage
Chopped onion

Cook until the meat is browned and the onion becomes soft.

Drain excess fat if needed.

Add minced garlic and cook for another 30 seconds until fragrant.

Step 2: Build The Sauce

Add to the skillet:

Marinara sauce
Crushed tomatoes
Tomato paste
Italian seasoning
Salt
Black pepper
Red pepper flakes (optional)

Stir everything together and allow it to simmer for a few minutes.

This helps develop a deeper flavor before slow cooking.

Step 3: Prepare The Cheese Mixture

In a bowl, combine:

Ricotta cheese
Parmesan cheese
Fresh herbs
Black pepper

Mix until smooth and creamy.

This creates the rich cheesy layer that makes baked ziti so delicious.

Step 4: Layer The Slow Cooker

Lightly grease the inside of your slow cooker.

Create layers:

A layer of meat sauce
A layer of uncooked ziti pasta
A layer of ricotta mixture
A layer of mozzarella cheese

Repeat the layers until all ingredients are used.

Finish with mozzarella and Parmesan on top.

Step 5: Slow Cook The Baked Ziti

Cover and cook:

Low setting: 3–4 hours
High setting: 1½–2½ hours

The pasta should be tender and the cheese should be melted and bubbly.

Avoid overcooking because pasta can become too soft.

Step 6: Rest Before Serving

Turn off the slow cooker and allow the baked ziti to rest for:

10–15 minutes

This helps the layers set and makes serving easier.

Garnish with:

Fresh basil
Extra Parmesan cheese

Serve warm.

Tips For The Best Slow-Cooker Baked Ziti
