Cheesy Baked Chicken Rigatoni Casserole

Ingredients You’ll Need

Pasta

  • 500 g rigatoni or penne pasta
  • salt for boiling water

Chicken Filling

  • 3 cups cooked shredded chicken (rotisserie works great)
  • 2 cups tomato sauce or marinara
  • 1/2 cup tomato paste or pizza sauce
  • 1 small onion, diced
  • 2 cloves garlic, minced
  • 1 tablespoon olive oil
  • salt & pepper
  • 1 teaspoon paprika
  • 1 teaspoon Italian seasoning

Cheese Layer

  • 2 cups shredded mozzarella
  • 1 cup cheddar or gouda
  • 1/2 cup parmesan (optional)

Optional Add-ins

  • mushrooms
  • bell peppers
  • spinach
  • olives
  • chili flakes
  • cream cheese
  • white sauce

🔥 Step 1 – Cook the Pasta

Bring a large pot of salted water to boil.

Add rigatoni.

Cook until al dente (slightly firm).

Don’t overcook — it will cook more in the oven.

Drain and set aside.

Tip: Toss with a little olive oil to prevent sticking.

🍗 Step 2 – Prepare the Chicken Filling

In a large pan over medium heat:

Add olive oil.

Cook onion and garlic until soft and fragrant.

Add shredded chicken.

Stir for 2–3 minutes.

Now add:

  • tomato sauce
  • tomato paste
  • spices
  • salt & pepper

Simmer 5–7 minutes.

You want a thick, rich sauce — not watery.

Taste and adjust seasoning.

This is where all the flavor builds.

Your kitchen will smell amazing already 😍

🧀 Step 3 – Mix Pasta with Sauce

In a big bowl combine:

  • cooked pasta
  • chicken sauce mixture

Mix until every piece of pasta is coated.

The sauce should hug the pasta nicely.

If it looks dry, add a little extra sauce.

🥘 Step 4 – Assemble the Casserole

Preheat oven to 180°C (350°F).

Grease a baking dish or foil tray.

Layer like this:

1️⃣ Half pasta mixture

2️⃣ Half cheese

3️⃣ Remaining pasta

4️⃣ Lots of cheese on top

Be generous with cheese.

The cheesy top crust is EVERYTHING.

Optional: sprinkle parmesan for extra flavor.

🔥 Step 5 – Bake Until Golden

Bake for 20–25 minutes.

You’ll know it’s ready when:

  • cheese is melted
  • edges bubbling
  • top slightly golden
  • smells irresistible

Optional: broil 2 minutes for extra browning.

Let rest 5–10 minutes before serving.

This helps it hold shape when slicing.

It’s cheesy, savory, slightly tangy from tomato, and super satisfying.
