Equipment

  • Large skillet
  • Knife and cutting board
  • Large pasta cooking pot
  • 9x13-inch baking dish
  • Oven and stove

Ingredients

  • 12 oz spaghetti
  • 4 tbsp unsalted butter
  • ½ cup onion, chopped
  • 2 garlic cloves, minced
  • 4 tbsp all-purpose flour
  • 2 cups low-sodium chicken broth
  • 1 tsp dry parsley
  • ½ tsp dry oregano
  • ½ tsp dry basil
  • ½ tsp red pepper flakes
  • ¼ tsp salt
  • Freshly ground black pepper to taste
  • 1 cup cheddar cheese, freshly shredded and divided
  • 1 cup mozzarella cheese, freshly shredded and divided
  • 1 cup half and half
  • 1- 10 oz diced tomatoes with green chiles
  • 3 cups shredded leftover rotisserie chicken

Instructions

  • Cook the spaghetti until al dente in a large pot of boiling salted water according to package instructions until al dente. Drain and set aside. Preheat the oven to 350 F
  • While the pasta is cooking, heat the butter in a large skillet over medium-high heat and cook the onion and garlic until translucent, about 2 minutes. Sprinkle and whisk the flour on top and cook until golden brown, about 2-3 more minutes.
  • Slowly whisk in the chicken broth until no lumps remain, and cook for about 3 minutes until thick. Season with salt, pepper, oregano, basil, parsley, and red pepper flakes.
  • Sprinkle half of the shredded cheddar and mozzarella into the skillet, and stir until melted.
  • Gently fold the cooked spaghetti, half and half, chicken, and diced tomatoes into the sauce mixture until everything is well combined. Be careful not to break the pasta.
  • Spoon the mixture into a greased 9x13-inch casserole dish and sprinkle the remaining cheddar and mozzarella on top. Bake for 20-25 minutes or until the cheese is melted and bubbly.
