How To Make Crockpot Baked Ziti
Step 1: Prepare Your Slow Cooker
- Create a foil collar by folding two 18×14-inch foil strips and lining the inside of your slow cooker insert. Spray with nonstick cooking spray.

Step 2: Cook the Meat and Aromatics
- Heat the oil in a large, deep pan over medium-high heat. Add the Italian sausage, breaking it into chunks as it cooks. Brown the sausage for about 7-8 minutes.
- Stir in the onion, cooking until translucent, about 4-5 minutes.
- Add the garlic, oregano, fennel, salt, and pepper. Stir and cook for 30-60 seconds until fragrant.

Step 3: Combine Pasta and Sauce
- Reduce heat to medium-low and add the raw ziti pasta. Stir constantly for 3-4 minutes until the pasta edges turn translucent.
- Stir in the crushed tomatoes and tomato sauce, scraping up any browned bits from the bottom of the pan.

Step 4: Assemble and Cook
- Transfer the mixture to your prepared slow cooker.
- Cover and cook on LOW for 3 hours or until the pasta is tender.

Step 5: Add Cheese and Serve
- Remove the foil collar. Spoon the ricotta cheese over the ziti, then sprinkle with mozzarella cheese.
- Cover and let the cheese melt for 20 minutes. Sprinkle with fresh basil.
- Serve warm alongside garlic bread and a green salad.

Cook’s Tools:
- slow cooker

- Cheese Swaps: Pureed cottage cheese can be used instead of ricotta for a lighter option.
- Spice It Up: Add crushed red pepper flakes for a spicy kick.
- Gluten-Free: Use gluten-free pasta.
- You can double this recipe with the following changes to the directions:
- When doubling this recipe, use a large crockpot that holds at least 6 quarts.
- After removing the foil collar, remove half of the pasta and spread 1 cup of ricotta and 1 cup of mozzarella over the top. Place the removed pasta on top of the cheese layers, and top with the remaining 1 cup of ricotta and mozzarella.
- Proceed with the remainder of the slow cooker baked ziti recipe.

Can I use a liner instead of foil?
Yes, that will work.
I’ve been there with the commissary! This looks just as delicious with the penne! Such a delicious and comforting meal. Love all that cheese.
I definitly do not miss shopping at the commissary, especially the ones OCONUS!
Love how easy this was to make right in my slow cooker! So flavorful and delicious!
Thank you!
Tasty recipe! My family really enjoyed it.
I’m so glad they enjoyed the recipe!
Yum! My family loves this recipe! I can’t wait to make this again soon!
This was fantastically delicious! So easy to make – I’ve never cooked pasta in the slow cooker from raw before and it was perfect.
Could this be doubled and prepared in an 8qt slow cooker? If so, how would the setting and time vary?
Thanks!
A doubles recipe will definitely fit in an 8-quart slow cooker. I would say increase the slow cooking time by 30 minutes.
Not sure what is meant by foil collar?
Looks at the middle picture just above the subtitle “Cook’s Tools”. That picture shows a foil collar. Basically, you’re just lining the sides of the slow cooker insert.
Can one use parchment paper instead of foil? I’ve stopped keeping foil in my house as parchment paper typically works better for what I need.
I wouldn’t recommend it. I could see parchment paper scorching in the slow cooker.
