Creamy Garlic Chicken & Mushroom Alfredo Spaghetti

Ingredients

For the pasta

Cooked chicken – sliced or shredded, tender and ready to toss into the sauce

Spaghetti or linguine – your choice of long pasta, cooked al dente

Mushrooms – sliced (cremini, button, or a mix for depth of flavor)

Garlic – minced, for aromatic richness

Onion – diced, to build a savory base

Olive oil & butter – for sautéing and flavor balance

Chicken broth – adds depth and keeps the sauce light yet flavorful

Heavy cream or half-and-half – for a luscious, creamy texture

Parmesan cheese – freshly grated, to melt into the sauce

Italian seasoning or thyme – for herbal warmth

Salt & black pepper – to season and balance flavors

Optional toppings

Fresh parsley – for a burst of freshness

Red pepper flakes – a touch of gentle heat

Extra parmesan – because you can never have too much cheese

1. Cook the pasta

Bring a large pot of salted water to a boil.

Cook the spaghetti or linguine until al dente according to package directions.

Drain, reserving about 1 cup of pasta water, and set aside.

2. Sauté the aromatics

In a large skillet, heat olive oil and butter over medium heat.

Add the diced onion and minced garlic, cooking until softened and fragrant, about 2–3 minutes.

3. Cook the mushrooms

Add the sliced mushrooms to the skillet and sauté until golden brown and tender, about 5 minutes.

4. Build the sauce

Pour in the chicken broth and heavy cream (or half-and-half).

Stir and let the mixture simmer gently until slightly thickened.

Reduce the heat, then stir in the Parmesan cheese, Italian seasoning (or thyme), salt, and black pepper.

5. Combine pasta and chicken

Add the cooked chicken and pasta to the skillet.

Toss everything together until the noodles are evenly coated in the creamy sauce.

Use a splash of reserved pasta water if needed to loosen the sauce.

6. Garnish and serve

Plate the pasta and finish with fresh parsley, extra Parmesan, and a sprinkle of red pepper flakes, if desired.

Serve immediately while warm and creamy.
