The Ingredients
Let’s break down the superstar ingredients of this dish. You will need:
- 4 cups cooked pasta of your choice, well-drained
- 1 to 1½ cups shredded mozzarella cheese
- 2 cups cooked, frozen, or leftover shredded chicken
- ½ teaspoon dried Italian herbs (basil, oregano blend)
- 1 jar of rich marinara sauce

How to Make 4 Ingredient Chicken Pasta Casserole?
Before we get into the nitty-gritty of the cooking process, just know that this casserole comes together in a snap. It’s perfect for busy weekdays or when you’re having a laid-back Sunday. Let me guide you through the steps.
Step 1: Preheat the Oven
First things first, you’ll want to preheat your oven to 350°F (175°C). This ensures that when your casserole is assembled, you can pop it directly into a hot oven and let the magic begin.
Step 2: Cook the Pasta
While the oven warms up, bring a large pot of salted water to boil. Cook your pasta according to the package instructions until al dente, which usually takes about 8-10 minutes. Drain the pasta well and return it to the pot.
Step 3: Combine Ingredients
Now comes the fun part. In the pot with the drained pasta, add the shredded chicken, dried Italian herbs, and marinara sauce. Stir gently until everything is nicely combined. You want every noodle to be kissed by that rich sauce.
Step 4: Add Cheese
Grab that mozzarella cheese and fold it into the pasta mixture. As the cheese starts to incorporate, you can already envision the melty goodness that’s about to come out of your oven.
Step 5: Transfer and Bake
Transfer your mixture into a greased 9×13-inch baking dish. Spread it out evenly so each bite has all the flavors. If you’re feeling wild, sprinkle a little extra mozzarella on top for an even cheesier finish. Bake uncovered for about 25-30 minutes, or until the cheese is bubbly and slightly golden.
Step 6: Serve and Enjoy!
Once out of the oven, allow the casserole to rest for about five minutes. This makes it easier to serve. Dish it up, and get ready for that first bite!
Notes
Here are some helpful tips to make your casserole even better:
- Mix in Veggies: Toss in some sautéed spinach, peas, or bell peppers to sneak in extra nutrients.
- Use a Variety of Cheeses: Experiment with a mix of cheeses, like cheddar or parmesan, for added flavor.
- Make it Spicy: Add red pepper flakes or diced jalapeños for a little heat.
- Dress Up the Marinara: Enhance your store-bought marinara by simmering it with garlic, onion, or fresh herbs before mixing it in.
- Customize Your Pasta: Use whole wheat or gluten-free pasta for a healthier or dietary-friendly option.
Storage Tips
Storing leftovers is simple. You can refrigerate your casserole in an airtight container for up to 3-4 days. If you want to save some for later, pack individual portions in freezer-safe containers. These can last up to 3 months in the freezer. Just reheat thoroughly in the oven or microwave.
