Main Ingredients

  • 12 oz dry spaghetti break in half if preferred
  • 3 cup cooked shredded chicken
  • 10 oz sliced mushrooms cremini or white
  • 1 cup chopped onion
  • 2 tsp minced garlic
  • 3.5 tbsp unsalted butter
  • 1 tbsp olive oil
  • 0.33 cup all-purpose flour
  • 0.25 cup dry white wine or sherry optional but recommended
  • 2.5 cup low-sodium chicken broth warm if possible
  • 1.5 cup half-and-half or use equal parts milk and cream
  • 4 oz cream cheese, softened cut into cubes
  • 1.25 cup Parmesan cheese, finely grated divided
  • 1 cup frozen peas no need to thaw
  • 1 tsp Italian seasoning or use dried thyme
  • 1.5 tsp kosher salt to taste
  • 0.75 tsp black pepper
  • 0.25 cup chopped fresh parsley plus extra for garnish
  • 0.75 cup panko breadcrumbs for topping
  • 1.5 tbsp melted butter for topping

Instructions

Preparation Steps

  • Heat oven to 375°F. Grease a 9x13-inch baking dish.
  • Boil spaghetti in salted water until just shy of al dente. Drain and set aside.
  • Warm olive oil and 2 tbsp butter in a large skillet over medium-high heat.
  • Brown mushrooms until they release liquid and develop color, about 6 minutes.
  • Stir in onion; cook until soft, 3 to 4 minutes. Add garlic; cook 30 seconds.
  • Melt remaining butter. Sprinkle in flour and cook, stirring, for 1 minute.
  • Deglaze with wine, scraping the pan. Whisk until smooth and slightly thick.
  • Slowly whisk in broth, then half-and-half. Simmer until creamy and thickened.
  • Blend in cream cheese until melted. Stir in 1 cup Parmesan, salt, pepper, and Italian seasoning.
  • Fold in chicken, peas, and parsley. Add cooked spaghetti and toss to coat.
  • Spread mixture in the baking dish. Mix panko with melted butter and remaining Parmesan; sprinkle over top.
  • Bake until bubbling and golden, 20 to 25 minutes. Rest 10 minutes before serving.

Notes

Swap in cooked turkey for the chicken, or add a handful of shredded mozzarella for extra stretch. Skip the wine and replace with more broth if you prefer. To make ahead, assemble, cover, and refrigerate up to 24 hours; add 5–10 minutes to the bake time. Leftovers reheat well with a splash of broth or milk.
