Chicken Preparation Options: Poaching Chicken: Follow the poaching instructions in the recipe. Using Leftover Chicken: Swap in 1 cup of cubed cooked chicken instead.
Poach the Chicken (Skip if Using Leftover or Cooked Chicken)
Cook the Chicken (or Use Leftover Chicken): Place the chicken in a 1 or 2-quart saucepan and cover it with cold water, about 1 inch above the chicken. Add the salt and bring to a gentle simmer—avoid boiling. Reduce the heat, cover, and cook for 10-12 minutes. Transfer to a plate, cover, and let it rest for 10 minutes before slicing to keep it juicy.Note: You can make sure the chicken is fully cooked with a thermometer - it should read 165°F, or ensure the juices run clear when pierced with a knife.
Make the Chicken Spaghetti
Cook Spaghetti: Bring a medium sized pot of water to a boil. Add the spaghetti and cook until al dente, about 7-8 minutes. Drain and set aside.
Sauté the Onions: Melt butter in an 8-inch skillet over medium heat. Add chopped onions and cook until softened, about 4 minutes.
Make the Sauce: Stir in 1 tablespoon of flour and cook for 1-2 minutes, stirring constantly. Add salt, pepper, and seasonings. Slowly pour in the broth and milk, stirring until smooth. Simmer until the sauce thickens, about 5 minutes.
Assemble the Dish: Chop the cooked chicken and place it in a bowl. Add chopped tomatoes and shredded cheddar cheese.
Combine Everything: Pour the warm sauce over the chicken and cheese, then add the cooked spaghetti. Stir until everything is evenly coated and the cheese has melted.
Serve: Transfer to a serving bowl and enjoy.
Notes
Preventing Sticky Spaghetti: If you're not using the cooked spaghetti right away, toss it with a little olive oil to keep it from sticking together.
Milk vs. Cream: Milk works well for the sauce, but for a richer texture, use heavy cream instead. If using heavy cream, skip the flour, as the cream naturally thickens the sauce.
Crumb Topping Option: For a crispy finish, mix breadcrumbs with melted butter, sprinkle over the dish, and bake at 350°F until golden brown.
Doubling the Recipe: Want to make chicken spaghetti for two? Simply double each ingredient to make more servings.
Note:This recipe is perfect for using leftover cooked chicken or rotisserie chicken, but if starting from raw, poaching is a quick option.
