Ingredients
Ricotta Cheese
Ricotta provides the creamy, soft layer that makes this baked ziti especially comforting. It blends with the Parmesan, eggs, basil, salt, and pepper to create a flavorful cheese mixture.
Eggs
Two eggs are mixed into the ricotta mixture. They help bind the ingredients together as the ziti cooks.
Salt
Salt enhances the flavor of the cheese and marinara sauce. Since Parmesan and marinara can already contain salt, season according to your taste.
Basil
Basil adds a pleasant Italian-inspired herbal flavor. Fresh basil can be used when available, although dried basil also works well.
Pepper
Black pepper adds subtle warmth and balances the creamy cheese mixture.
Parmesan Cheese
Parmesan contributes a savory, nutty flavor and adds another layer of cheesiness to the dish.
The recipe uses 1/4 cup Parmesan cheese in the ricotta mixture, with additional grated Parmesan used on top before serving.
Marinara Sauce
Marinara sauce provides moisture and rich tomato flavor. You can use your favorite store-bought marinara or prepare a homemade version.
Gluten-Free Penne Pasta
The recipe calls for uncooked penne pasta. For a gluten-free version, choose gluten-free penne.
Shredded Mozzarella Cheese
Mozzarella melts into a deliciously gooey layer between the pasta and ricotta mixture. It also creates the cheesy topping that makes baked ziti so appealing.
How to Make Crock Pot Baked Ziti
Step 1: Prepare the Slow Cooker
Spray the entire slow cooker insert generously with non-stick cooking spray. This helps prevent the pasta and cheese from sticking and makes cleanup easier.
Step 2: Prepare the Ricotta Mixture
In a large mixing bowl, combine the ricotta cheese with:
- 2 eggs
- 1/4 cup Parmesan cheese
- Basil
- Salt
- Pepper
Mix until the ingredients are evenly combined and the mixture is creamy.
Step 3: Add the First Layer of Sauce
Spread a layer of marinara sauce across the bottom of the prepared slow cooker.
This first layer of sauce is important because it provides moisture underneath the uncooked pasta.
Step 4: Add the Pasta
Arrange a layer of uncooked penne pasta over the marinara sauce.
Try to distribute the pasta as evenly as possible so it cooks consistently.
Step 5: Add the Ricotta
Take 5 scoops of the ricotta mixture and drop them evenly over the layer of pasta.
There is no need to spread the ricotta perfectly. It will soften and blend into the other layers as the ziti cooks.
Step 6: Add Mozzarella
Sprinkle a layer of shredded mozzarella cheese over the ricotta mixture.
The mozzarella will melt during cooking and create the gooey, cheesy texture associated with baked ziti.
Step 7: Repeat the Layers
Repeat the layering process two more times:
- Marinara sauce
- Uncooked penne pasta
- Ricotta mixture
- Shredded mozzarella
For the final layer, finish with marinara sauce, shredded mozzarella cheese, and grated Parmesan cheese.
Step 8: Slow Cook
Cover the slow cooker and cook on HIGH for 2 1/2 hours.
Cooking times can vary slightly depending on your slow cooker, so check the pasta toward the end of the cooking time.
The pasta should be tender and the cheese should be melted and bubbly.
Step 9: Serve
Once the Crock Pot Baked Ziti is finished, carefully serve it while warm.
Top each serving with additional grated Parmesan cheese for an extra savory finish.
Important Cooking Tips
Don’t Boil the Pasta First
One of the convenient features of this recipe is that the penne is added uncooked. The pasta cooks in the marinara sauce and moisture released during slow cooking.
Keep the Layers Even
Try to distribute the pasta, ricotta, mozzarella, and sauce evenly. This helps ensure that the entire dish cooks consistently.
Don’t Open the Lid Too Often
Every time you remove the slow cooker lid, heat escapes. Keeping the lid closed helps maintain the cooking temperature and allows the pasta to cook properly.
Watch the Cooking Time
Slow cookers can vary in temperature. Begin checking the pasta around the expected finishing time rather than allowing it to cook significantly longer than necessary.
Overcooked pasta can become soft or mushy.
How to Make This Recipe Gluten-Free
Making this dish gluten-free is simple.
Use certified gluten-free penne pasta and check the labels of your marinara sauce, Parmesan, mozzarella, and other ingredients if you need to strictly avoid gluten.
Always check packaging because ingredient formulations can vary between brands.
How to Make It Spicy
If you enjoy a little heat, add red pepper flakes to either the ricotta mixture or marinara sauce.
Start with a small amount and increase it according to your preferred spice level.
Variations to Try
Add Ground Beef
For a heartier meal, browned ground beef can be added between the layers. Make sure the meat is fully cooked before incorporating it into the dish.
Add Italian Sausage
Cooked Italian sausage can add extra savory flavor and a touch of spice.
Add Vegetables
You can incorporate vegetables such as:
- Spinach
- Mushrooms
- Bell peppers
- Zucchini
- Chopped onions
Cook vegetables that release a lot of moisture before adding them so the final dish doesn’t become watery.
Add More Herbs
Italian seasoning, oregano, parsley, or additional basil can be used to enhance the flavor.
What to Serve with Crock Pot Baked Ziti
This cheesy pasta dish can be served on its own, but it also pairs beautifully with simple side dishes.
Consider serving it with:
- Garlic bread
- A crisp green salad
- Roasted vegetables
- Steamed broccoli
- Caesar salad
- Garlic-seasoned vegetables
A light salad is particularly nice because its freshness balances the richness of the cheese and pasta.
Storage
Allow leftover baked ziti to cool before transferring it to an airtight container.
Store leftovers in the refrigerator and enjoy them within a few days, following standard food-safety practices.
For longer storage, portions can be frozen in freezer-safe containers. Thaw refrigerated portions before reheating for more even warming.
How to Reheat Leftovers
Individual portions can be reheated in the microwave until heated through.
For larger portions, reheat gently in the oven or another suitable method. Adding a small amount of marinara sauce can help prevent the pasta from drying out.
Frequently Asked Questions
Can I use regular penne instead of gluten-free penne?
Yes. Gluten-free penne is included specifically for those who need or prefer a gluten-free version. Regular penne can be used if gluten is not a concern.
Do I need to cook the pasta before putting it in the crock pot?
No. This recipe specifically uses uncooked penne pasta. The pasta cooks directly in the slow cooker.
Can I use homemade marinara sauce?
Absolutely. Homemade marinara is a great option if you prefer making your own tomato sauce.
Can I use another type of pasta?
Penne is recommended because it works well with the layering method. If substituting another pasta, keep in mind that different shapes and sizes can have different cooking requirements.
Can I prepare the ricotta mixture ahead of time?
Yes. The ricotta, eggs, Parmesan, basil, salt, and pepper mixture can be combined ahead of time and refrigerated until you’re ready to assemble the dish.
Why is my pasta still firm?
Slow cookers vary, and pasta may need sufficient moisture and heat to become tender. Make sure the pasta is well covered by the sauce and avoid opening the lid frequently during cooking.
Why did my baked ziti become mushy?
Overcooking is one of the most common reasons pasta becomes mushy. Start checking the pasta as you approach the recommended 2 1/2-hour cooking time.
Can I make this recipe ahead of time?
You can prepare the ricotta mixture and have your ingredients ready in advance. For best results, assemble and cook the dish according to the recipe rather than leaving uncooked pasta sitting in sauce for an extended period.
