Step‑by‑Step Instructions for Creamy Pesto Chicken Pasta Bake
Step 1: Cook the Pasta
Start by bringing a large pot of salted water to a rolling boil. Add 12 ounces of penne pasta and cook according to package instructions until you achieve al dente texture, roughly 10-12 minutes. Once cooked, drain the pasta thoroughly and set it aside to cool slightly while you prepare the chicken.
Step 2: Sauté the Chicken
In a large skillet set over medium heat, pour in 2 tablespoons of olive oil. Once the oil is shimmering, add 1 pound of diced chicken breast, seasoning it with 1 teaspoon each of salt and pepper. Cook the chicken for about 6-8 minutes, stirring occasionally until it's browned and cooked through. After cooking, remove the chicken from the skillet and place it on a plate.
Step 3: Wilt the Spinach
Using the same skillet, add 3 cups of fresh spinach over medium heat. Stir and cook for about 2-3 minutes until the spinach wilts and reduces in volume. You want it beautifully bright and tender. Once done, combine the spinach with the cooked chicken for the next step.
Step 4: Combine the Sauce
In a large mixing bowl, blend together 1 cup of basil pesto and 1 cup of heavy cream until smooth and creamy. Stir in the previously cooked chicken, wilted spinach, the cooked penne pasta, and if you wish, ½ teaspoon of red pepper flakes for a spicy kick. Mix in half of the shredded mozzarella cheese, creating a luscious filling for your Creamy Pesto Chicken Pasta Bake.
Step 5: Prepare for Baking
Preheat your oven to 350°F (175°C) to get it nice and hot. Grease a baking dish to prevent sticking, then transfer the delicious pasta mixture into the dish, spreading it evenly. Top it off with the remaining shredded mozzarella cheese and sprinkle ½ cup of grated Parmesan cheese on top for an irresistible golden crust.
Step 6: Bake to Perfection
Place the baking dish in the preheated oven and bake for 20-25 minutes. Keep an eye on it, as you'll want the cheese to become bubbly and golden brown, giving you a beautiful, inviting crust. Once it reaches that perfect melty texture, remove it from the oven.
Step 7: Garnish and Serve
After baking, let the Creamy Pesto Chicken Pasta Bake cool for a few minutes before serving. For a fresh touch, garnish with some sprigs of basil or extra red pepper flakes if desired. Scoop it onto plates, and get ready for a delightful meal filled with comforting flavors!
