Ingredients for Crockpot Baked Ziti

This recipe uses simple ingredients to create a flavorful homemade pasta dinner. The sauce is made from scratch, but it’s surprisingly easy to prepare.

For the Ziti

1 pound ziti pasta
2 Tablespoons butter
Garlic salt, to taste
Grated Parmesan cheese, for serving

For the Homemade Ziti Sauce

1 large can stewed tomatoes, approximately 28 ounces, finely chopped
1 can tomato paste, 6 to 8 ounces
1 1/2 standard 16.9-ounce bottles of water, approximately 3 cups, plus more if needed
Garlic salt, to taste
1 Tablespoon minced onion
1 teaspoon Italian seasoning
2 teaspoons ground oregano
1 teaspoon dried sweet basil
2 to 3 heaping Tablespoons brown sugar
1/2 teaspoon minced garlic
Red pepper flakes, optional

Optional Cheesy Additions

If you love extra-cheesy baked ziti, you can add:

1 to 2 cups shredded mozzarella cheese
1/2 cup additional grated Parmesan cheese
1/2 cup ricotta cheese, optional
Fresh parsley or basil, for garnish

The original recipe is delicious with Parmesan cheese alone, but adding mozzarella gives the pasta a gooey, melted cheese topping.

How to Make Crockpot Baked Ziti

Step 1: Preheat the Crockpot

Turn your crockpot to the HIGH setting while the pasta is cooking. This helps warm the slow cooker before adding the cooked ziti.

Step 2: Cook the Ziti Pasta

Bring a large pot of water to a boil and cook 1 pound of ziti according to the package directions, preferably just until al dente.

Drain the pasta well and transfer it to the warm crockpot.

Sprinkle the pasta with garlic salt and add 2 Tablespoons of butter. Stir gently until the butter melts and coats the pasta.

Place the lid on the crockpot while you prepare the sauce.

Step 3: Prepare the Tomatoes

In a large, heavy-bottomed saucepan, add the stewed tomatoes.

Using a spoon or potato masher, chop and crush the tomatoes until they are finely broken down and almost smooth.

This creates a wonderful homemade tomato sauce texture without large pieces of tomato.

Step 4: Add the Tomato Paste and Water

Add the tomato paste and approximately 3 cups of water to the saucepan.

Stir well over low heat until the tomato paste is completely blended with the tomatoes and water.

If the sauce seems too thick, add a little additional water until you reach your preferred consistency.

Step 5: Season the Sauce

Sprinkle the sauce with garlic salt and add the minced onion, Italian seasoning, ground oregano, sweet basil, and brown sugar.

Stir everything together until the seasonings and brown sugar are well incorporated.

Step 6: Bring the Sauce to a Gentle Boil

Increase the heat to medium-high and bring the tomato sauce to a gentle boil.

Allow it to boil gently for approximately 5 minutes, stirring frequently to prevent the sauce from sticking or scorching.

Step 7: Add Garlic and Simmer

Stir in the minced garlic.

Reduce the heat to low and allow the sauce to simmer for approximately 30 minutes, stirring occasionally.

As the sauce simmers, the tomatoes, herbs, garlic, and brown sugar blend together to create a rich, flavorful homemade Italian-inspired sauce.

Step 8: Taste and Adjust the Seasonings

Taste the sauce and adjust the ingredients as needed.

If you prefer a sweeter tomato sauce, add a little more brown sugar.

For a stronger Italian herb flavor, add additional Italian seasoning or oregano.

If you enjoy spicy pasta sauce, sprinkle in a small amount of red pepper flakes.

Step 9: Add the Sauce to the Crockpot

Carefully ladle the hot homemade tomato sauce over the cooked ziti in the crockpot.

Stir gently until all the pasta is coated in the delicious sauce.

Cover and allow the pasta to sit in the warm sauce for approximately 10 to 15 minutes, just long enough to absorb some of the flavor and heat through.

If the pasta is already hot, use the WARM setting rather than continuing to cook on HIGH. Avoid holding it for too long, as the pasta can become overly soft.

Step 10: Add Parmesan Cheese and Serve

Sprinkle the pasta generously with grated Parmesan cheese.

For an extra-cheesy version, add shredded mozzarella, cover, and heat just until the cheese melts.

Serve warm and enjoy!

Jennie’s Thoughts

I love a good homemade pasta dinner, and this Crockpot Baked Ziti is such an easy way to make something comforting and delicious without having to turn on the oven.

The homemade tomato sauce is really what makes this recipe special. I love the combination of garlic, oregano, Italian seasoning, and sweet basil, but the brown sugar is one of my favorite little additions. It helps balance the acidity of the tomatoes and gives the sauce a slightly sweet, rich flavor that tastes wonderful with the pasta.

One of my favorite tricks is to toss the cooked ziti with butter and garlic salt before adding the sauce. It’s such a simple step, but it gives the pasta an extra layer of flavor.

And of course, you can never go wrong with Parmesan cheese! I love adding a generous sprinkle right before serving. If you’re craving something really cheesy, you can also add mozzarella and let it melt right over the top.

This is a wonderful recipe for those evenings when you want a cozy homemade dinner without a lot of fuss. Serve it with warm garlic bread and a simple salad, and you’ve got a delicious meal everyone will enjoy.

Tips for Making the Best Crockpot Baked Ziti

Don’t Overcook the Pasta

Because the pasta will sit in warm tomato sauce, it’s important not to overcook it initially. Cooking the ziti just until al dente helps prevent it from becoming too soft.

Make the Sauce Ahead of Time

You can prepare the homemade tomato sauce in advance and store it in the refrigerator for up to 3 to 4 days. Reheat it thoroughly before adding it to the cooked pasta.

Adjust the Sweetness

The brown sugar helps balance the acidity of the tomatoes, but you can adjust the amount depending on your preferences. Start with 2 heaping Tablespoons and add more after tasting if desired.

Add More Cheese

For a gooey, cheesy pasta dish, sprinkle shredded mozzarella over the top of the ziti after adding the sauce. Cover the crockpot briefly until the cheese melts.

Keep an Eye on the Sauce

Tomato sauce can thicken as it simmers. If it becomes too thick, stir in a little water until it reaches the consistency you like.

Don’t Leave the Pasta on High for Hours

This recipe uses the crockpot primarily to keep the prepared pasta warm and allow the sauce to coat it. Because the ziti is already cooked, prolonged cooking can make it mushy.

Easy Crockpot Baked Ziti Variations

There are so many delicious ways to customize this recipe!

Cheesy Crockpot Baked Ziti

Add shredded mozzarella and grated Parmesan cheese over the top of the pasta. Cover until the cheese is melted and deliciously gooey.

Crockpot Baked Ziti with Ground Beef

Brown 1 pound of ground beef in a skillet, drain the grease, and stir it into the homemade tomato sauce before adding the sauce to the pasta.

Crockpot Baked Ziti with Italian Sausage

Cook and crumble 1 pound of Italian sausage and add it to the tomato sauce for a heartier, savory pasta dinner.

Spicy Crockpot Baked Ziti

Add crushed red pepper flakes to the sauce for a little extra heat.

Crockpot Baked Ziti with Ricotta

Spoon small dollops of ricotta cheese throughout the sauced pasta and sprinkle with mozzarella and Parmesan for a creamier, cheesier dish.

Crockpot Baked Ziti with Spinach

Stir a handful of cooked, well-drained spinach into the pasta sauce for an easy way to add vegetables.

What to Serve with Crockpot Baked Ziti

This hearty pasta dish is delicious on its own, but it’s even better served with a few simple sides.

Garlic Bread: Warm, buttery garlic bread is perfect for soaking up the delicious homemade tomato sauce.

Homemade Breadsticks: Soft, fluffy breadsticks are a wonderful addition to any Italian-inspired dinner.

Caesar Salad: A crisp Caesar salad adds a fresh contrast to the rich pasta.

Roasted Broccoli: Oven-roasted broccoli with garlic and Parmesan makes a delicious vegetable side dish.

Italian Chopped Salad: Fresh lettuce, tomatoes, cucumbers, and Italian dressing pair beautifully with baked ziti.

Homemade Dinner Rolls: Soft, buttery dinner rolls are always a family favorite.

Can You Make Crockpot Baked Ziti Ahead of Time?

Yes! You can make the tomato sauce ahead of time and store it in an airtight container in the refrigerator for up to 3 to 4 days.

When you’re ready to serve dinner, cook the pasta, reheat the sauce until hot, and combine everything in the crockpot.

For the best texture, I recommend cooking the pasta shortly before serving rather than leaving cooked pasta in the crockpot for several hours.

How to Store Leftover Crockpot Baked Ziti

Allow the leftovers to cool slightly, then transfer them to airtight containers and refrigerate promptly, within 2 hours of cooking.

Store leftover ziti in the refrigerator for up to 3 to 4 days.

To reheat, place a serving in a microwave-safe dish with a small splash of water or additional tomato sauce. Cover loosely and heat until steaming hot throughout, reaching 165°F.

You can also reheat leftovers in a covered baking dish in the oven.

Can You Freeze Crockpot Baked Ziti?

Yes! This pasta dish can be frozen, although the pasta may become slightly softer after thawing and reheating.

Allow the ziti to cool, transfer it to freezer-safe containers, and freeze for up to 2 to 3 months for the best quality.

Thaw overnight in the refrigerator and reheat thoroughly before serving.

You can also freeze the homemade tomato sauce separately, which is a wonderful way to make future pasta dinners even easier.

Frequently Asked Questions

Can You Put Cooked Pasta in a Crockpot?

Yes! Cooked pasta can be added to a crockpot with hot sauce to keep it warm briefly before serving. Avoid cooking it for extended periods because it can become mushy.

Do You Have to Boil Ziti Before Putting It in the Crockpot?

For this recipe, yes. The ziti is cooked on the stovetop before being combined with the homemade tomato sauce in the crockpot.

Can I Use Penne Instead of Ziti?

Absolutely! Penne, rigatoni, or another short tubular pasta can be substituted for ziti.

Can I Use Jarred Pasta Sauce?

Yes! If you’re short on time, you can substitute your favorite prepared pasta sauce. However, the homemade sauce gives this recipe its signature flavor.

Can I Add Mozzarella Cheese?

Definitely! Shredded mozzarella is a delicious addition and gives the pasta a wonderful melted, cheesy topping.

Why Is My Crockpot Ziti Dry?

Pasta absorbs liquid as it sits in the sauce. If the ziti becomes too dry, stir in a little additional warm tomato sauce or water.

Is Crockpot Baked Ziti the Same as Oven Baked Ziti?

Not exactly. Traditional oven-baked ziti is usually layered with cheese and baked until bubbly, sometimes with a browned top. This crockpot version uses precooked pasta and homemade sauce, then finishes in the slow cooker without baking. It has the same comforting pasta flavors but a softer, saucier finish.
