Step 1: Preheat your oven to 350°F (175°C). This will ensure the pasta bake is cooked evenly and bubbly when it’s time to eat.
Step 2: In a large pot, bring salted water to a boil. Add the pasta and cook according to the package instructions until al dente. Drain the pasta and set it aside.
Step 3: In a large mixing bowl, combine the cooked pasta, pesto, heavy cream, shredded chicken, frozen peas, and sun-dried tomatoes. Stir until everything is well coated and evenly distributed.
Step 4: Pour the pasta mixture into a greased baking dish. Spread it out evenly with a spatula.
Step 5: Sprinkle the shredded mozzarella cheese generously over the top of the pasta mixture. This will create a delicious, gooey topping as it bakes.
Step 6: Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the cheese is melted and bubbly, and the edges are slightly golden.
Step 7: Once baked, remove the dish from the oven and let it cool for a few minutes before serving. This Pesto Chicken Pasta Bake pairs wonderfully with a fresh salad or some garlic bread.
