Chicken Caprese Pasta Casserole

This comforting, dinner-worthy bake blends the familiar flavors of a Caprese salad with hearty pasta and tender chicken. It’s the sort of recipe that shows up on busy weeknights and on the table when friends drop by—melty cheese, bright basil, juicy tomatoes, and a tangy, creamy tomato sauce all baked until bubbling and golden. If you love easy, flavor-forward meals that come together mostly in one dish, this Chicken Caprese Pasta Casserole will be on repeat.

Why this recipe works

There’s a reason the Caprese flavor combo (tomato, basil, mozzarella) is timeless: it’s simple and balanced. In this casserole, the classic trio gets hearty support from pasta and chicken, while grated parmesan and a touch of heavy cream round out the sauce so it clings to every rigatoni or penne. A splash of balsamic vinegar deepens the tomato flavor without overwhelming the dish. The result is an elevated comfort food that still feels light and fresh thanks to plenty of basil and juicy grape tomatoes.

Notes before you start

• Use about 1 pound chicken, cooked and chopped (roughly two chicken breasts). You can poach, roast, or pan-sear the breasts—just make sure they’re cooked through and roughly chopped before mixing into the casserole.
• Either rigatoni or penne works well; both hold sauce in their ridges and tubes so every bite is saucy.
• Cube the 6 ounces of mozzarella into small pieces so it melts evenly through the pasta. Reserve 6 fresh mozzarella rounds for the top—they’ll add a gorgeous, melty finish.
• Keep a few halved grape tomatoes and one tablespoon of chopped basil back for garnish so the finished casserole looks bright and fresh.

Ingredients

• 1 pound chicken, cooked and chopped, about 2 chicken breasts
• 1 pound pasta, Rigatoni or Penne
• 2 cups marinara sauce
• ¼ cup heavy cream
• 1 tablespoon balsamic vinegar
• ¼ cup grated parmesan cheese
• 6 ounces mozzarella cheese, cut into cubes
• 1 pint grape tomatoes, cut in half, reserve some for garnish
• ¼ cup fresh basil, chopped, plus 1 tablespoon for garnish
• 6 fresh mozzarella rounds for the top

Equipment

You’ll need a large pot to cook the pasta, a mixing bowl, a 9×13-inch casserole dish (or similar), and an oven preheated to bake the casserole. A slotted spoon or tongs for transferring pasta and a spatula for mixing will make things easy.

Step-by-step instructions

1. Preheat the oven. Set your oven to 375°F (190°C) so it’s ready once the pasta and sauce are combined.
2. Cook the pasta. Bring a large pot of salted water to a boil. Add 1 pound pasta (rigatoni or penne) and cook according to the package directions until al dente—slightly firm to the bite. Drain the pasta and return it to the pot or place it in a large mixing bowl. Do not overcook, because it will finish cooking in the oven.
3. Prepare the sauce mixture. In a separate bowl or measuring cup, combine 2 cups marinara sauce with ¼ cup heavy cream, 1 tablespoon balsamic vinegar, and ¼ cup grated parmesan cheese. Stir until smooth and uniform; the cream will mellow the acidity and help the sauce cling to the pasta.
4. Add the chicken. Ensure you have 1 pound chicken, cooked and chopped, about 2 chicken breasts. Fold the chopped chicken into the drained pasta so the pieces are distributed evenly.
5. Mix in cheeses and tomatoes. Add 6 ounces mozzarella cheese, cut into cubes, plus the halved grape tomatoes (1 pint, cut in half). Stir these gently into the pasta and chicken so the tomatoes and cheese become well distributed.
6. Combine pasta and sauce. Pour the marinara-cream-parmesan mixture over the pasta, chicken, tomatoes, and cubed mozzarella. Use a large spoon or spatula to toss everything together until the pasta is evenly coated and the ingredients are mixed throughout.
7. Add basil and transfer to the casserole dish. Stir in ¼ cup fresh basil, chopped, saving 1 tablespoon for garnish. Transfer the sauced pasta mixture into a 9×13-inch casserole dish or similar oven-safe baking dish, spreading it into an even layer.
8. Top with fresh mozzarella rounds. Place the 6 fresh mozzarella rounds evenly across the top of the assembled casserole. Nestle them slightly into the pasta so they’ll melt into the dish as it bakes.
9. Bake until bubbly. Put the casserole in the preheated oven and bake for about 20–25 minutes, or until the cheese is melted and the sauce is hot and bubbling around the edges. If you like a lightly browned top, place the casserole under the broiler for 1–2 minutes at the end—watch closely so the cheese doesn’t burn.
10. Garnish and serve. Remove the casserole from the oven and let it sit for 5 minutes. Scatter the reserved halved grape tomatoes and the remaining 1 tablespoon chopped basil over the top for a fresh finish. Serve warm, scooping generous portions so each plate has a mix of saucy pasta, chicken, and melted mozzarella rounds.

Serving suggestions

This Chicken Caprese Pasta Casserole is satisfying on its own, but a few simple sides elevate the meal. A crisp green salad with a lemon vinaigrette cuts through the richness, and some crusty bread (or garlic bread) is perfect for mopping up extra sauce. If you want a lighter contrast, serve it with steamed green beans or a simple arugula salad with shaved parmesan.

Make-ahead and storage tips

• To make ahead: Assemble the casserole without baking, cover tightly with foil, and refrigerate for up to 24 hours. When you’re ready to bake, remove foil and add an extra 5–10 minutes to the bake time if the casserole is chilled.
• To freeze: Bake the casserole once, cool completely, then wrap tightly and freeze for up to 3 months. Thaw in the refrigerator overnight and reheat in a 350°F (175°C) oven until warmed through.
• Leftovers: Store cooled leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in the microwave or in a 350°F (175°C) oven until heated through.

Ingredient swaps and tips

• If you prefer a lighter dairy option, you can use half-and-half instead of the ¼ cup heavy cream, but the sauce will be slightly less rich.
• For a more pronounced balsamic flavor, drizzle an extra 1–2 teaspoons of balsamic vinegar over the top just before serving, but don’t add more to the sauce than listed unless you want a tangier profile.
• Try using fresh, homemade marinara if you have time; the fresher the tomato flavor, the brighter the casserole will taste.
• If you don’t have fresh mozzarella rounds for the top, thin slices of fresh mozzarella or extra cubed mozzarella will work—just distribute them evenly so the top melts uniformly.

Frequently asked questions

Can I use a different protein? Yes—substitute the chicken with cooked turkey or even a plant-based chicken-style product if you prefer. Just keep the amount to 1 pound so the balance of ingredients stays the same.

Do I have to cook the chicken before adding it? Yes; the recipe lists 1 pound chicken, cooked and chopped. Raw chicken should not be mixed into the casserole because the short baking time is meant to melt cheese and heat through, not fully cook raw poultry.

What if I only have shredded mozzarella? Shredded mozzarella will work—use 6 ounces cut into cubes per the ingredient list was meant to ensure even melting, but shredded will also melt well throughout the dish. Keep the 6 fresh mozzarella rounds for the top if you want that signature appearance.
