Ingredients for this Creamy Chicken Casserole

• 3 cups cooked rotini pasta
• 2 cups cooked chicken breast, shredded or cubed
• 1 ½ cups shredded mozzarella cheese
• ½ cup shredded cheddar cheese (optional for extra flavor)
• 1 cup cherry tomatoes, halved or diced
• 2 tablespoons olive oil
• 1 tablespoon minced garlic
• 1 teaspoon Italian seasoning
• Salt and pepper to taste
• ¼ cup chopped fresh parsley (for garnish)
• ½ cup heavy cream or whole milk (for added creaminess)
• ¼ cup grated Parmesan cheese (for the top)

Step 1: Prepare the Ingredients

Start by preheating your oven to 375°F (190°C). While it’s heating up, cook your rotini pasta according to the package instructions until al dente. Drain and set aside. At the same time, ensure your chicken is cooked and either shredded or cubed into bite-sized pieces. This is a great use for leftover rotisserie chicken!

Step 2: Sauté for Extra Flavor

In a large skillet, heat the olive oil over medium heat. Add minced garlic and cook for about 30 seconds until fragrant. Toss in the diced cherry tomatoes and sauté for 2–3 minutes, just enough to soften them slightly and release their juices. Sprinkle in the Italian seasoning, salt, and pepper. Remove from heat.

Step 3: Combine Everything

In a large mixing bowl, combine the cooked pasta, chicken, sautéed tomato mixture, and heavy cream. Mix well to coat everything evenly. Stir in 1 cup of shredded mozzarella and all the cheddar cheese (if using) for that creamy richness. Adjust seasoning if needed.

Step 4: Layer in a Casserole Dish

Transfer the mixture into a lightly greased 9×13-inch casserole dish. Spread it out evenly. Sprinkle the remaining mozzarella cheese and the Parmesan on top for a perfect cheesy crust.

Step 5: Bake to Perfection

Bake in the preheated oven for 20–25 minutes, or until the cheese is melted, bubbly, and lightly golden brown on top. For extra browning, broil for the last 2 minutes—but watch it carefully!

---

Step 6: Garnish and Serve

Remove from the oven and let it rest for about 5 minutes before serving. Sprinkle fresh chopped parsley over the top for a burst of color and freshness. Pair with a simple green salad or garlic bread for a complete meal.

Frequently Asked Questions

1. Can I use a different type of pasta?

Absolutely! Penne, fusilli, or macaroni all work well. Just avoid delicate pasta shapes that may fall apart when baked.

2. Is it possible to make this casserole ahead of time?

Yes! Assemble everything, cover, and refrigerate for up to 24 hours. Bake when ready to serve.

3. Can I make this casserole gluten-free?

Just substitute the rotini with your favorite gluten-free pasta. Double-check that other ingredients (like sauces and cheese) are certified gluten-free.

4. What veggies can I add to this dish?

Great options include spinach, mushrooms, zucchini, or bell peppers. Sauté them first to avoid excess moisture.

5. Can I use canned tomatoes instead of fresh cherry tomatoes?

Yes, diced canned tomatoes (drained) will work fine, though fresh ones offer a brighter flavor.

6. What’s the best cheese combo for extra flavor?

Mozzarella gives it that gooey texture, but mixing in a sharp cheddar, gouda, or even a bit of blue cheese adds amazing depth.

7. How do I keep the casserole from drying out?

Make sure not to overbake and use enough cream or milk. Cover with foil during baking if needed to retain moisture.

8. Is this kid-friendly?

Very much so! It’s creamy, cheesy, and full of familiar flavors that most kids love. You can even sneak in some finely chopped veggies.
