This 4-ingredient slow cooker memorial ziti is exactly the kind of no-fuss comfort food I lean on during busy weeks and family get-togethers. Everything starts with dry ziti straight in the slow cooker—no boiling water, no extra pans—and then you just dump in three more ingredients, stir, and walk away. It’s cozy, saucy, and cheesy, and it feels a little special even though it’s mostly hands-off. I started making a version of this after a family memorial gathering where we needed something simple that could feed a crowd and stay warm for hours, and it’s become one of those recipes my family now requests on repeat.
Serve this slow cooker ziti hot, straight from the crock, with a simple green salad (bagged salad totally works) and some crusty garlic bread or buttered dinner rolls to soak up the extra sauce. A side of steamed green beans or roasted broccoli balances out the richness without adding much work. If you like a little heat, pass red pepper flakes at the table. For a fuller spread, pair it with a light fruit salad or sliced melon to keep things fresh and easy.
4-Ingredient Slow Cooker Ziti
Servings: 6

Ingredients
16 ounces dry ziti pasta
24 ounces jarred marinara or pasta sauce
2 cups water
2 cups shredded mozzarella cheese, divided
Directions
Lightly spray the inside of a 4- to 6-quart slow cooker with nonstick cooking spray to help prevent sticking.
Pour the dry ziti pasta evenly into the bottom of the slow cooker so it forms a fairly even layer.
In a medium bowl or large measuring cup, whisk together the jarred marinara sauce and the water until well combined. The mixture will look like a thinner, bright red sauce—this is what you’ll pour over the pasta so it cooks up tender.
Slowly pour the thinned sauce mixture over the dry ziti in the slow cooker, making sure to cover all of the pasta. Use the back of a spoon to gently press down any exposed noodles so they’re mostly submerged in the liquid.
Sprinkle 1 cup of the shredded mozzarella cheese evenly over the top of the saucy pasta. Do not stir.
Cover the slow cooker with the lid and cook on HIGH for 2 to 2 1/2 hours, or on LOW for 3 1/2 to 4 hours, until the pasta is tender but not mushy. Try not to lift the lid during the first 1 1/2 hours so the heat and moisture stay trapped inside.
Once the pasta is cooked to your liking, gently stir the ziti from the bottom to distribute the sauce and melted cheese throughout. Sprinkle the remaining 1 cup of shredded mozzarella over the top in an even layer.
Cover again and cook on HIGH for an additional 10 to 15 minutes, just until the cheese on top is melted and bubbly.
Turn the slow cooker to WARM if you’re not serving right away. Serve the ziti straight from the crock, scooping down to the bottom so everyone gets plenty of pasta, sauce, and cheese in each serving.
Variations & Tips
You can easily tweak this 4-ingredient base to fit your family. Use any shape of short dry pasta you have on hand, like penne or rigatoni, but keep an eye on the cook time the first time you try a new shape and test for doneness early. Swap the mozzarella for an Italian blend cheese, or stir in a handful of grated Parmesan along with the first cup of cheese for extra flavor. If you want a bit more protein without adding another ingredient to the slow cooker, serve the finished ziti alongside pre-cooked Italian sausage or rotisserie chicken. For extra veggies, you can stir in a bag of thawed, well-drained frozen spinach or some leftover roasted vegetables during the last 20 to 30 minutes of cook time so they heat through without watering down the sauce.
Food safety tips: Make sure the pasta and sauce mixture reaches a safe, steamy temperature throughout; slow cookers can vary, so always test in the center before serving. Keep the lid on as much as possible to maintain heat and proper cooking temperature. Once cooked, do not leave the ziti on the WARM setting for more than 2 hours; after that, cool leftovers quickly and refrigerate in shallow containers. Reheat leftovers until they’re piping hot all the way through before eating. If the pasta has absorbed a lot of sauce when reheating, stir in a splash of water or extra sauce to loosen it up.
