Make Ricotta Mixture
Combine ricotta with egg whites, Parmesan, mozzarella, salt, and pepper.
Add Noodles
Place half the uncooked noodles in the bottom of your slow cooker.
Layer Ingredients
Add a layer of spaghetti sauce, add a layer of the ricotta mixture, and then add the mushrooms and spinach.
Finish Layers
Repeat the process with another layer of noodles, add more sauce, and finish with the rest of the ricotta.
Cook
Finish with a layer of sauce, then cook on low for 4 hours.
More Cheese
About five minutes or so before you serve the ziti, sprinkle mozzarella on top. Cover to melt and then serve!
💡 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.
- Fontina 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 one time! If you're reheating from frozen, let the ziti thaw in the fridge first.

Love this recipe! So delicious! Have you freezed this before? If so what are the steps for reheating?
Kristin King says
Hi Katie, I'm so glad you like this recipe! Yes, I have frozen this and it went fairly well. First I cooled it completely on the counter, then I placed it in an airtight freezer-safe container and placed it in the refrigerator to cool it even further for a few hours. Then I placed it in the freezer. You can store it there for 3 months or so. When ready to use it, transfer the container to the fridge and allow the ziti to thaw overnight or longer. Once thawed it can be reheated at 350 degrees F in the oven for 15-30 minutes, loosely covered with foil to prevent drying out (start checking at 15 minutes to see if it is hot yet).

Judee says
Thank you for this wonderful recipe. I like to make baked ziti when I have company and this would certainly make it alot easier. I would even let people help themselves from the crock pot. Perfect for holiday parties...
Dorothy says
My husband loves this recipe! Just make sure to spin the spinach and dry off the mushrooms as much as possible to prevent the ziti from getting too soupy.
Kristin King says
Good tip, thanks! I am glad your husband likes it! 🙂
dorothy says
can you cook on high for two hours instead?
Kristin King says
I have not actually tried that, Dorothy. Sorry! I have only tried it on low. You could give it a shot, but just make sure you have a backup plan in case it doesn't turn out! 🙂
Mel Farrell says
what size slow cooker works best for this?
Kristin King says
I use a 5 quart slow cooker. I have to kind of pack it in because the fresh spinach takes up a lot of room, but it cooks down pretty fast. Let me know if you have any other questions!
Marlene Stindle says
This sounds really good, but I would add cooked Italian sausage and green pepper! Thanks
Jenny says
Where the noodle supposed to be cooked when you put them into the crockpot?
Kristin King says
No, the noodles should not be cooked when you put them in. If they are, they will be complete mush when done. Although it will be very tasty mush! 🙂
