Ingredients

1 lb. linguine

3 tbsp. butter, divided

2 c. mushrooms, thinly sliced

Kosher salt

Freshly ground black pepper

2 cloves garlic, minced

1 lb. boneless skinless chicken breasts, cut into 1" pieces

2 tbsp. all-purpose flour

1 1/2 c. low-sodium chicken broth 

1 1/2 c. heavy cream

2/3 c. freshly grated Parmesan

Preparation

Step 1Preheat oven to 350°. Prepare linguine according to package instructions. Drain, reserving half a cup pasta water. Step 2In a large skillet over medium heat, melt 1 tablespoon butter. Add mushrooms and season with salt and pepper. Cook until mushrooms are mostly tender, 4 to 5 minutes, then add chicken. Season again with salt and pepper and cook, stirring occasionally, until chicken is lightly golden, 5 minutes. Add garlic and cook until fragrant, 1 minute more. Transfer mixture to a large plate or bowl. Step 3Return skillet to medium heat and melt remaining 2 tablespoons butter. Whisk in flour until completely combined, then slowly whisk in broth and heavy cream. Bring to simmer over medium heat, stirring occasionally and allowing sauce to thicken, about 10 minutes. Step 4Add pasta and chicken mixture to skillet and toss to combine. Add pasta water to loosen sauce if needed. Sprinkle with parmesan and bake until sauce is bubbling and cheese is golden, 25 minutes.

Can I use a different type of pasta for this recipe? Absolutely! Tetrazzini is usually made with spaghetti, linguine, or egg noodles, but feel free to use your favorite cut. If bowties are your thing, don’t let us stop ya! What other vegetables can I add to this dish?  Spinach, tomatoes, or chopped bell peppers would be delicious additions! Dark leafy greens like kale or chard would be good, just be sure to sauté whatever veggie you choose before adding to your baking dish. What kind of dish can I bake this in? As long as it all fits, any oven-safe baking dish will do. (That includes a cast iron skillet!) Can this be frozen? Yep, simply cover tightly and freeze! When ready to eat, remove from the freezer and let defrost in your refrigerator for 24 hours in advance. Once defrosted, cover with foil and bake at 350° for 30 minutes. Remove foil, bake 15 minutes longer, and serve! Made it? Let us know how it went in the comment section below!
