Crispy topped pasta casserole with chicken, basil pesto, and melted mozzarella cheese.

# What You Need:

→ Pasta

01 - 10.5 oz penne or rigatoni

→ Chicken

02 - 2 medium chicken breasts (about 12 oz), diced

→ Pesto & Sauce

03 - 1/2 cup basil pesto
04 - 1 1/4 cups tomato passata or marinara sauce
05 - 2 cloves garlic, minced
06 - 2 tbsp olive oil

→ Cheese

07 - 2 cups shredded mozzarella
08 - 1/4 cup grated Parmesan cheese

10 - Fresh basil leaves, for garnish (optional)

# Directions:

01 - Preheat the oven to 390°F.
02 - Cook the pasta in a large pot of salted boiling water until just al dente. Drain and set aside.
03 - While the pasta cooks, heat olive oil in a large skillet over medium heat. Add diced chicken, season with salt and pepper, and sauté for 5–7 minutes until cooked through and lightly golden. Add minced garlic and cook for another 1 minute.
04 - Stir in the tomato passata (or marinara sauce) and half of the pesto. Simmer for 2–3 minutes, then remove from heat.
05 - In a large mixing bowl, combine the cooked pasta, chicken mixture, half of the mozzarella, and remaining pesto. Stir gently until evenly mixed.
06 - Transfer the mixture to a lightly greased baking dish. Top with remaining mozzarella and Parmesan.
07 - Bake in the preheated oven for 20 minutes, or until the cheese is melted and golden and the sauce is bubbling.
08 - Let rest for 5 minutes before garnishing with fresh basil and serving.

# Expert Tips:

01 -
  • The pesto infuses every single noodle with bright basil flavor that you just cannot achieve with marinara alone
  • It comes together in under an hour but tastes like you spent all afternoon lovingly preparing it
  • The leftovers reheat beautifully for lunch the next day, if there are any
02 -
  • Undercook your pasta by about two minutes since it will continue cooking in the oven and you do not want mushy noodles
  • Reserve a splash of pasta water before draining, it helps bind everything together if the sauce seems too thick
03 -
  • Mix some pesto directly into the pasta before combining with the chicken, this ensures flavor in every single bite
  • Broil for the last 2 minutes if you want extra crispy cheese edges on top
