I first threw this together on a Tuesday evening when I had chicken that needed cooking and a jar of pesto lurking in the fridge. The way the kitchen filled with that basil and tomato aroma while it baked made the whole house feel cozy. My roommate actually came downstairs asking what smelled so good, and she is not easily impressed by weeknight dinners.

Last winter my sister came over exhausted from work and I made this for us. She sat on the counter watching the cheese turn golden through the oven door, and we ended up eating straight from the baking dish while catching up about everything and nothing.

Ingredients

  • Pasta: Penne or rigatoni catches all that sauce in ridges and corners, and I learned stopping it at al dente is crucial since it cooks more in the oven
  • Chicken breasts: Dicing them into bite sized pieces means every forkful gets the perfect meat to pasta ratio
  • Basil pesto: Store bought works perfectly fine but homemade adds that bright freshness that makes people ask what your secret is
  • Tomato passata or marinara: This creates the saucy base that ties everything together, so choose one you actually like drinking by the spoonful
  • Garlic: Minced fresh adds that aromatic kick that wakes up the whole dish
  • Olive oil: Use this to sauté the chicken so it gets those golden bits of flavor
  • Shredded mozzarella: Creates that irresistible cheese pull everyone loves
  • Grated Parmesan: Adds the salty finish that cuts through the rich sauce
  • Salt and pepper: Season your chicken generously before cooking, it makes all the difference
  • Fresh basil leaves: Optional but they add that pop of color and fresh aroma right before serving

Make It Your Own

I have added sun dried tomatoes when I needed to use up a jar and the tangy brightness worked beautifully. Sometimes I toss in roasted vegetables from the night before, anything that can hold up to baking becomes part of the meal.

Shortcuts That Work

Rotisserie chicken shreds perfectly into this when you are in a rush. I have used it on weeknights and honestly the seasoned flavor from the rotisserie bird adds something extra.

Serving Suggestions

A crisp white wine like Pinot Grigio cuts through the rich cheese and pesto beautifully. I also love a simple green salad with vinaigrette to balance the hearty pasta.

  • Crusty bread never hurts for soaking up that sauce
  • Keep extra Parmesan on the table
  • This pairs beautifully with that crisp white wine

Recipe Questions & Answers

Can I make this ahead of time?

Yes, assemble the entire casserole up to 24 hours in advance, cover tightly, and refrigerate. Bake for an additional 10-15 minutes if baking cold from the refrigerator.

What pasta shapes work best?

Penne and rigatoni are ideal because their tubes capture sauce and cheese effectively. Fusilli, ziti, or macaroni also work well in this baked dish.

Can I freeze leftovers?

Portion leftovers into airtight containers and freeze for up to 3 months. Thaw overnight in the refrigerator and reheat in a 180°C oven until hot throughout.

How do I know when it's done?

The casserole is ready when the cheese is melted and golden brown, and you see bubbles around the edges. This typically takes 20 minutes at 200°C.

What can I serve with this?

A crisp green salad with vinaigrette balances the richness. Garlic bread or roasted vegetables like broccoli or bell peppers also make excellent sides.

Can I use rotisserie chicken?

Absolutely. Shredded rotisserie chicken works perfectly and cuts prep time significantly. Simply skip the chicken cooking step and add it directly to the sauce mixture.

Ingredient List

Pasta

01 10.5 oz penne or rigatoni pasta

Chicken

01 2 medium chicken breasts (about 12 oz), diced into 1-inch pieces

Pesto & Sauce

01 1/2 cup basil pesto, store-bought or homemade
02 1 1/4 cups tomato passata or marinara sauce
03 2 cloves garlic, minced
04 2 tbsp olive oil

Cheese

01 2 cups shredded mozzarella cheese
02 1/4 cup grated Parmesan cheese

Seasoning

01 Salt and freshly ground black pepper to taste
02 Fresh basil leaves for garnish

How To Make It

Step 01

Preheat Oven: Preheat the oven to 390°F. Prepare a baking dish by lightly greasing with cooking spray or olive oil.

Step 02

Cook Pasta: Bring a large pot of salted water to a boil. Add the penne or rigatoni and cook until just al dente, about 1-2 minutes less than package directions. Drain thoroughly in a colander and set aside.

Step 03

Prepare Chicken: While pasta cooks, heat olive oil in a large skillet over medium-high heat. Season diced chicken generously with salt and pepper. Add to the hot skillet and sauté for 5-7 minutes until cooked through and lightly golden, stirring occasionally.

Step 04

Add Aromatics and Sauce: Add minced garlic to the skillet and cook for 1 minute until fragrant. Pour in tomato passata or marinara sauce and half of the pesto. Stir well and simmer for 2-3 minutes until slightly thickened. Remove from heat.

Step 05

Combine Everything: In a large mixing bowl, combine the cooked pasta, chicken mixture, half of the shredded mozzarella, and remaining pesto. Gently fold together until pasta is evenly coated with sauce.

Step 06

Assemble the Bake: Transfer the pasta mixture to the prepared baking dish, spreading it evenly. Top with the remaining mozzarella and grated Parmesan cheese.

Step 07

Bake Until Golden: Bake in the preheated oven for 20 minutes, or until the cheese is melted and bubbly with golden-brown spots. The sauce should be bubbling around the edges.

Step 08

Rest and Serve: Remove from the oven and let the casserole rest for 5 minutes before serving. This allows the cheese to set slightly for cleaner portions. Garnish with fresh basil leaves if desired.
