Cook the Pasta: Begin by boiling a large pot of salted water. Cook the pasta according to package instructions until al dente. Drain and set aside.
Sauté Vegetables: In a large pot, heat the olive oil over medium heat. Add the diced onion, carrots, and celery. Sauté for about 5-7 minutes, or until the vegetables are softened.
Add Chicken: Stir in the shredded chicken and frozen peas. Cook for another 2-3 minutes until the peas are heated through.
Make the Sauce: Sprinkle the flour over the chicken and vegetable mixture, stirring to coat evenly. Cook for a minute to lightly toast the flour. Slowly pour in the chicken broth while stirring continuously.
Thicken and Flavor: Add the heavy cream, dried thyme, garlic powder, and season with salt and pepper. Bring the mixture to a gentle simmer, allowing it to thicken for about 5-10 minutes. Stir frequently to avoid lumps.
Combine with Pasta: Once the sauce has thickened, add the cooked pasta to the pot. Gently mix everything together until the pasta is well coated with the creamy sauce.
Serve: Spoon the Chicken Pot Pie Pasta into bowls and garnish with fresh parsley before serving.
