Ingredients

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

1 pound ground Italian sausage
1 small yellow onion, finely chopped
3 cloves garlic, minced
1 (24-ounce) jar marinara sauce
1 (15-ounce) can tomato sauce
½ cup water or low-sodium chicken broth
1 teaspoon dried Italian seasoning
½ teaspoon salt
¼ teaspoon black pepper
¼ teaspoon crushed red pepper flakes, optional
1 (16-ounce) box uncooked ziti pasta
1 cup ricotta cheese
1 ½ cups shredded mozzarella cheese
½ cup grated Parmesan cheese
Fresh basil or parsley, chopped, for garnish

Directions

1. In a large skillet over medium heat, add the ground Italian sausage and chopped onion. Cook for 6 to 8 minutes, or until the sausage is browned and fully cooked. Drain any excess fat if needed. Stir in the minced garlic and cook for 1 additional minute until fragrant.

2. Stir in the marinara sauce, tomato sauce, water or broth, Italian seasoning, salt, black pepper, and crushed red pepper flakes if using. Bring the mixture to a boil, then reduce the heat and let it simmer for 3 to 5 minutes.

3. Lightly grease a 6-quart slow cooker with nonstick spray. Spread a thin layer of the meat sauce on the bottom.

4. Begin layering by adding one-third of the uncooked ziti, followed by one-third of the meat sauce, dollops of ricotta, a sprinkle of mozzarella, and a sprinkle of Parmesan. Repeat the layers two more times, ending with cheese on top.

5. Cover and cook on low for 3 ½ to 4 hours, or until the pasta is tender but not mushy.

6. Turn off the slow cooker and let the ziti sit uncovered for 10 to 15 minutes to set. Garnish with freshly chopped basil or parsley before serving.

Variations

For added nutrition and color, stir chopped spinach, zucchini, or bell peppers into the meat sauce before layering.

Swap the ricotta cheese for cottage cheese if you prefer a slightly lighter texture. For a richer, creamier result, substitute part or all of the ricotta with cream cheese.

If you prefer a meatless version, replace the sausage with sautéed mushrooms or a plant-based ground alternative.

You can also use penne or rigatoni if ziti is not available, keeping the cooking time the same and checking for doneness toward the end.

Storage/Reheating

Allow leftovers to cool completely before transferring them to an airtight container. Store in the refrigerator for up to 4 days.

To reheat, microwave individual portions in 30-second intervals, stirring occasionally, until heated through. You can also reheat larger portions in a 350°F oven, covered with foil, until warmed throughout.

This dish freezes well. Place cooled portions in freezer-safe containers and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.

FAQs

Can I use a different type of pasta?

Yes, penne or rigatoni work well as substitutes. Choose a similar-sized pasta shape for even cooking.

Do I need to cook the pasta before adding it to the slow cooker?

No, the pasta goes in uncooked. It will cook directly in the sauce as the dish simmers.

Can I make this recipe ahead of time?

You can prepare the meat sauce a day in advance and refrigerate it. Assemble and cook in the slow cooker when ready.

What if my pasta turns out too soft?

Overcooking can cause mushy pasta. Check for doneness around the 3 ½-hour mark to avoid overcooking.

Can I cook this on high instead of low?

Cooking on low is recommended for even results. If using high, monitor closely, as the pasta may cook faster and become too soft.

How can I make it spicier?

Add extra crushed red pepper flakes or use hot Italian sausage for more heat.

Is it necessary to grease the slow cooker?

Yes, lightly greasing the slow cooker helps prevent sticking and makes cleanup easier.

Can I double the recipe?

If your slow cooker is large enough, you can double the ingredients. Make sure not to overfill beyond the recommended capacity.

How do I know when the ziti is done?

The pasta should be tender but still hold its shape. Insert a fork to test for doneness.

Can I add extra cheese on top?

Absolutely. For an extra cheesy finish, sprinkle additional mozzarella on top during the last 15 minutes of cooking.
