How to Make Chicken Pasta Casserole Recipe
Step 1: Preheat and Prepare the Pasta
Start by preheating your oven to 375°F (190°C). Meanwhile, cook the pasta in boiling salted water until it’s just tender but still has a slight bite — this ensures it won’t get mushy once baked. Drain and set aside to keep it ready for mixing with the other flavorful ingredients.
Step 2: Cook the Chicken
In a large skillet, warm the olive oil over medium-high heat. Season the chicken pieces with salt and pepper, then cook them until they are golden brown and fully cooked through, which usually takes about 6 to 8 minutes. The searing adds such a lovely texture and locks in the juiciness. Remove the chicken from the skillet and set aside for the next step.
Step 3: Sauté Vegetables
Using the same skillet, toss in the garlic, onion, and red bell pepper. Sauté for a few minutes until the onion becomes translucent, letting those aromatics release their charm. Then add the mushrooms and cook until they soften and develop rich flavors—this builds the hearty base of your sauce.
Step 4: Add Tomatoes and Simmer
Stir in the drained diced tomatoes and bring the mix to a gentle simmer. Letting it cook down for about 3 to 4 minutes helps thicken the sauce slightly while intensifying those fresh tomato notes, perfectly balancing the creaminess that comes next.
Step 5: Stir in Cream and Combine Ingredients
Lower the heat and pour in the heavy cream, carefully stirring it into the vegetable mixture. Let it cook for a couple more minutes to meld everything. Then, add the cooked pasta, chicken, and half of your mozzarella and Parmesan cheeses. Sprinkle in the oregano, basil, and red pepper flakes if you want that subtle heat. Gently toss everything together so the flavors get cozy.
Step 6: Bake to Perfection
Transfer the entire mixture into a greased 9×13-inch baking dish. Top it with the remaining mozzarella and Parmesan cheeses to create that golden, bubbling crust we all love. Bake in your preheated oven for 20 to 25 minutes, or until the cheese is beautifully melted, bubbly, and lightly golden on top.
Step 7: Rest and Garnish
Once out of the oven, let the casserole rest for a few minutes. This pause lets the sauce thicken a bit more and makes it easier to serve. Don’t forget to sprinkle with fresh parsley right before bringing this comforting dish to the table.
How to Serve Chicken Pasta Casserole Recipe

Garnishes
Fresh herbs like parsley or basil add a lovely burst of color and a hint of freshness that balances the richness. A light dusting of extra Parmesan right before serving is a nice touch, too.
Side Dishes
This hearty chicken pasta casserole pairs wonderfully with a crisp green salad or steamed green beans to add some crunch and lighten the meal. Garlic bread also makes a fantastic side, soaking up every last bit of that creamy sauce.
Creative Ways to Present
For a fun twist, serve individual portions in ramekins straight out of the oven, allowing each person to enjoy a personalized cheesy crust. You can also add roasted cherry tomatoes or drizzle a little balsamic glaze on top for a fancy, flavor-packed finish.
Make Ahead and Storage
Storing Leftovers
If you have leftovers (though this casserole goes fast!), store them in an airtight container in the refrigerator. It will stay fresh for up to 3 days, making a perfect grab-and-go meal.
Freezing
This Chicken Pasta Casserole Recipe freezes well. Before baking, cover the casserole tightly with foil and freeze for up to 2 months. When you’re ready to enjoy, thaw overnight in the refrigerator and then bake as directed, adding a few extra minutes if needed.
Reheating
Reheat leftovers in the oven at 350°F (175°C) until warmed through and bubbly, about 15 to 20 minutes. You can also microwave individual portions, though baking helps keep that cheesy topping delightfully melty.
