Slow Cooker Baked Ziti Recipe
This is a super easy way to make an iconic, Italian favorite–baked ziti! I love how this recipe doesn’t require you to pre-boil the noodles. When cooked on high the raw noodles cook perfectly. I used my casserole crock* to make this ziti but you can definitely use your favorite oval shaped slow cooker. I added dollops of ricotta on the top after the ziti was cooked through for a creamy taste. If you don’t love ricotta you can easily try out cottage cheese, cream cheese or even sour cream.
I used regular ziti because I couldn’t find whole wheat ziti* at the store but if you can find whole wheat I recommend using it. Whole wheat noodles just seem to work a lot better in the slow cooker, plus they are healthier. This is a great recipe to feed a busy family. Keep your ziti warm in the slow cooker until everyone has a chance to come home and eat. This would also be a great recipe to make for a neighbor or a friend who just had a baby.

I cannot count how many recipes or the amount of time I have been making Karen’s ummmazing “Instant Pot” recipes. I am embarrassed to say that this is the first time I’ve decided to try a Crockpot recipe of Karen’s. Her Ziti with Pepperoni recipe was mind blowing. The ease of getting this “from scratch” recipe into the Crockpot, the deep flavor, the texture of the pasta, etc. etc. All so dang easy! We just went crazy over this dish. I also have the same casserole cooker, but as I halved the recipe, I just used my 2 quart Crockpot. I am serving this dish to everyone we invite into our home for dinner. Thank you karen SO much.
NICE! Don’t you just love the casserole crock? It is so fun. But the 2 quart also sounds great. I love the smaller crockpot options.
You're on a roll with the casserole crock!
This looks so wonderful, Karen. I've got to try it!
