Ingredients
- 12 oz linguine or spaghetti
- 4 cups rotisserie chicken, shredded or diced (or cook 1.5 lbs of chicken breast)
- 2 tbsp olive oil
- 1 lb button mushrooms, thickly sliced
- 1 medium onion, finely chopped
- 4 garlic cloves, minced
- 4 tbsp unsalted butter
- 1/3 cup all-purpose flour
- 3 cups low-sodium chicken broth
- 1 tbsp lemon juice
- 2 cups half & half (or substitute with equal parts milk & heavy cream)
- 1 1/2 tsp sea salt, plus more to taste
- 1/4 tsp freshly ground black pepper
- 1/4 cup parsley, chopped, plus more to garnish
- 1 1/2 cups shredded mozzarella cheese
Instructions
- Preheat the oven to 350°F (175°C) and butter a 9×13-inch casserole dish.
- Cook the pasta in a large pot of salted boiling water until barely al dente (do not overcook). Reserve 1/2 cup of the pasta cooking water, then drain the pasta and set aside.
- Heat olive oil in a large skillet over medium-high heat. Add the sliced mushrooms and sauté for 3 minutes until softened. Add the diced onions and cook until soft and golden, about 5-7 minutes. Add the minced garlic and cook for 1 minute until fragrant. Transfer this mixture to the cutting board with the chicken.
- In the same pot, melt the butter and whisk in the flour until lightly golden, about 1 1/2 minutes. Gradually whisk in the chicken broth, lemon juice, salt, and pepper until smooth. Add the half & half and bring to a simmer. Taste and adjust seasoning with more salt and pepper if needed.
- Add the chicken, mushroom mixture, parsley, and sauce into the pot with the pasta. Stir to combine. If you want a saucier texture, add 1/2 cup of the reserved pasta water.
- Spread the mixture evenly into the prepared casserole dish. Top with shredded mozzarella.
- Cover with foil and bake for 20 minutes. Remove the foil and continue baking for 15 minutes. Optionally, broil for the last 1-2 minutes to get golden spots on top.
Notes
- For a lighter version, substitute half & half with a mixture of milk and heavy cream in equal parts.
- This dish can be made ahead and frozen for future meals.
- Use a rotisserie chicken to save time, or cook chicken breasts for a fresher alternative.
- Adjust seasoning to your preference, especially the salt and pepper.
