💡 Expert Tips and Tricks
- You can use frozen spinach if you like, but be sure to let it thaw and remove any excess liquid.
- Add ground beef, ground turkey, meatballs, or sausage layered between the layers of sauce for some extra protein.
- Feel free to switch up the orders of the layers if you like, but I've found everything cooks the best when layered like this.
❔ FAQs
Yes, as long as there's some kind of liquid along with the pasta it'll cook fine.
Adding veggies to ziti adds moisture, so be sure to get rid of any moisture before you add them, especially the spinach!
If you want a much thicker result, you can make a cornstarch slurry by combining equal parts cornstarch and water and then mixing it into the pasta bake.
📝 Substitutions and Variations
- Swap out the mushrooms for zucchini, eggplant, or bell peppers if you prefer.
- For some added flavor, use a dash of red pepper flakes or some Italian seasoning in the ricotta mixture.
- Fontine and provolone are great substitutes for or additions to mozzarella.
- Sprinkle with fresh chopped herbs like parsley or basil for more pops of color and herbal flavor.
Kristin’s Kitchen Tip
Feel free to add other seasonings, different types of cheeses, or other kinds of pasta to customize this dish to your liking!
🥡 Storage and Reheating
Transfer any leftovers to an airtight container and store in the fridge for 3 to 4 days. You can also freeze your ziti for several months at a time.
To reheat, microwave individual portions until they're heated through again. You can also put everything back in the oven to reheat more at a time! If you're reheating from frozen, let the ziti thaw in the fridge first.

Erica (@Erica's Recipes)
this sounds so tasty! I've never cooked pasta in the crockpot like this, but I think I may have to give it a go. Sounds like a great idea on a busy Saturday or Sunday when I'm around the house, but want something easy for dinner.
Bernadette
Hi Kristin. I love waking up on Friday morning and reading your post as I drink my hot tea. Your recipes are wonderful, and you are an excellent writer (A+) who makes me smile. The baked ziti is one dish I can make while running here and there and everywhere! Thanks so much for this idea.
Kristin King
Thanks Bernadette, you always make my day with your nice comments! 🙂 I hope you and the family are well and enjoying summer. I am sure there is some excitement happening around your house as you get ready for another to head off to college. Where did the time go? It seems these kids just grew up all of a sudden. Have a great weekend, and please tell your hubby we say hello! 🙂
Renee@Renee's Kitchen Adventures
Oooo...I gotta try this one. I've always gotten pasta mush when I've tried to make pasta in the slow cooker!
Cheryl
When do you put in the spinach?
Kristin King
Oh my goodness, I totally forget an entire step! I have fixed it now, thank you so much for letting me know!
Carrie @Frugal Foodie Mama
Oh, this sounds right up my alley! 🙂 LOVE using my slow cooker, but you are right- it is easy to overcook the pasta to mush when making it in a slow cooker. Can't wait to try this recipe!
