  • 9x13 Casserole Dish

Ingredients
  

Main Ingredients

  • 2 chicken breasts boneless, skinless (about 1.5 lb)
  • 1 tbsp olive oil
  • 0.5 tbsp salt for pasta water
  • 8 oz spaghetti uncooked
  • 0.25 cup salted butter
  • 1 onion diced
  • 2 cloves garlic minced
  • 0.25 cup all-purpose flour
  • 2 cups chicken broth
  • 0.5 tsp salt
  • 0.25 tsp black pepper freshly cracked
  • 0.5 tsp Italian seasoning
  • 1 cup heavy cream
  • 10 oz diced tomatoes with green chiles drained (like Rotel)
  • 1 cup shredded cheddar cheese divided
  • 1 cup shredded mozzarella cheese divided

Instructions
 

  • Preheat oven to 375°F. Slice chicken breasts in half lengthwise. Heat olive oil in a skillet and sear chicken on both sides until golden and cooked through. Set aside to rest, then chop into bite-sized pieces.
  • Bring a pot of salted water to boil. Cook spaghetti until al dente. Drain and set aside.
  • In the same skillet, melt butter. Add diced onion and garlic, sauté 3–4 minutes until soft and fragrant.
  • Sprinkle in flour and stir constantly for 2–3 minutes to cook off the raw flour taste and start a roux.
  • Slowly whisk in chicken broth until smooth and thickened. Season with salt, pepper, and Italian seasoning.
  • Stir in heavy cream. Add half of the cheddar and mozzarella cheese. Stir until melted and creamy.
  • Add chopped chicken, drained tomatoes, and cooked spaghetti. Toss until evenly coated in the sauce.
  • Transfer to a 9×13-inch casserole dish. Top with remaining cheeses and bake for 25 minutes or until bubbly and golden.
  • Let rest for 5 minutes before serving for the best texture and flavor.

Notes

For extra flavor, use freshly shredded cheese and don’t forget to salt your pasta water. You can easily make this ahead of time and bake when ready to eat.
