Step‑by‑Step Instructions for Creamy Pesto Chicken Pasta Bake
Step 1: Boil the Pasta
Start by bringing a large pot of salted water to a rolling boil over high heat. Add the 12 ounces of penne pasta and cook according to package instructions until al dente, usually around 8-10 minutes. Once done, drain the pasta and set it aside, allowing the steam to escape while you prepare the other ingredients.
Step 2: Sauté the Chicken
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add 1 pound of diced chicken breast that's seasoned with 1 teaspoon of salt and 1 teaspoon of black pepper. Cook for about 6-8 minutes, stirring occasionally, until the chicken is browned and cooked through. Remove the chicken from the skillet and set it aside on a plate to keep warm.
Step 3: Wilt the Spinach
Using the same skillet, add 3 cups of fresh spinach and sauté for 2-3 minutes, stirring occasionally until wilted. The vibrant green color of the spinach will signify it's ready to come off the heat. Once wilted, transfer the spinach to the plate with the chicken, ensuring you capture all those delightful flavors in the skillet.
Step 4: Mix the Sauce
In a large mixing bowl, combine 1 cup of basil pesto with 1 cup of heavy cream. Stir this luscious mixture until well blended. Then, fold in the cooked chicken, sautéed spinach, the drained penne pasta, and, if desired, ½ teaspoon of red pepper flakes for a touch of heat. Sprinkle in half of the 1 cup of shredded mozzarella cheese, mixing everything until it's well coated with that creamy goodness.
Step 5: Prepare for Baking
Preheat your oven to 350°F (175°C). Next, grease a large baking dish to prevent sticking. Carefully pour the creamy pasta mixture into the baking dish, spreading it evenly. Top it off with the remaining mozzarella cheese and ½ cup of grated Parmesan cheese, creating a cheesy layer that will become beautifully golden while baking.
Step 6: Bake the Dish
Place the baking dish in the preheated oven and bake for 20-25 minutes, or until the cheese is bubbly and turns a lovely golden brown. You can peek through the oven door; the aroma of the creamy pesto chicken pasta bake will surely tempt you, but be patient for those final moments!
Step 7: Serve and Garnish
Once baked to perfection, remove the dish from the oven and let it rest for a few minutes. Garnish with fresh basil leaves for a pop of color and added flavor. Serve hot and watch as your family and friends dive into this delicious Creamy Pesto Chicken Pasta Bake.
