📝 Instructions

11 steps
1

Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish and set aside.

2

Cook the spaghetti according to package instructions until al dente. Drain and set aside.

3

Heat 1 tablespoon of olive oil in a large skillet over medium heat. Season the chicken breast with salt, pepper, and dried thyme. Cook the chicken for 6-8 minutes per side until golden and cooked through. Remove from the pan, let it rest for a few minutes, then shred or cube into bite-sized pieces.

4

In the same skillet, add the remaining olive oil and 2 tablespoons of butter. Sauté the minced garlic for about 30 seconds until fragrant, then add the sliced mushrooms. Cook for 5-7 minutes until the mushrooms have released their liquid and are golden brown. Set aside.

5

Reduce the heat to low and melt the remaining butter in the skillet. Sprinkle the flour over the melted butter and whisk continuously for 1-2 minutes to cook out the raw flour taste.

6

Gradually whisk in the chicken broth and milk, stirring constantly to avoid lumps. Bring the mixture to a simmer and cook for 4-5 minutes until the sauce has thickened.

7

Stir in the Parmesan cheese and season with additional salt and pepper to taste. Add the cooked mushrooms and shredded chicken into the sauce and mix well.

8

Combine the cooked spaghetti with the sauce mixture, ensuring the pasta is fully coated. Transfer the mixture to the prepared baking dish.

9

Sprinkle the mozzarella, cheddar, and breadcrumbs evenly over the top of the pasta.

10

Bake in the preheated oven for 20-25 minutes or until the top is golden brown and bubbly.

11

Remove the dish from the oven and let it cool for 5 minutes before serving. Garnish with chopped parsley, if desired.
