Instructions
Bring a large pot of salted water to a boil. Add the fettuccine and cook according to package instructions until al dente, about 8-10 minutes. Drain and set aside.
In a large skillet, heat olive oil and 1 tablespoon of butter over medium heat. Add the chopped onion and sauté until translucent, about 3-4 minutes. Add the sliced mushrooms and minced garlic; cook for another 5 minutes until the mushrooms are soft.
Reduce the heat to low, then sprinkle in the dried thyme, garlic powder, salt, and pepper. Stir well. Pour in the cream and chicken broth, stirring to combine. Add the frozen peas and cook for another 2-3 minutes until heated through.
In the skillet, add the shredded chicken to the sauce mixture, stirring well. Gently fold in the cooked fettuccine until everything is evenly coated with the creamy sauce. If the mixture looks too thick, you can add a little more chicken broth or cream to achieve the desired consistency.
Preheat your oven to 350°F (175°C). Transfer the tetrazzini mixture to a greased 9x13 inch baking dish. Sprinkle the grated Parmesan cheese evenly over the top. Dot with the remaining 2 tablespoons of butter, cut into small pieces.
Place the dish in the oven and bake for 20-25 minutes until the top is golden and bubbling.
Remove from the oven and let it cool for a few minutes. Garnish with chopped fresh parsley before serving.
Notes
For a dairy-free option, substitute cream with coconut milk.
