Step-by-Step Cooking Method

4.1 Prep

• Cook the spaghetti in salted water until just al dente. Drain and set aside.
• Shred the cooked chicken using forks or your hands. You can use leftovers or rotisserie.

4.2 Sauté Aromatics

• In a large skillet, heat olive oil over medium heat.
• Sauté the finely diced onion until translucent (about 5 minutes).
• Add minced garlic and cook for 1–2 minutes until fragrant.

4.3 Build the Sauce

• Stir in the cream of chicken soup, Rotel, sour cream, and chicken broth.
• Let it simmer for about 5 minutes until it’s smooth and slightly thickened.

4.4 Incorporate Cheese & Veggies

• Add half the Monterey Jack cheese to the sauce and stir until melted.
• Mix in optional veggies like spinach, peas, or mushrooms here.

4.5 Combine With Spaghetti

• Add the cooked pasta to the skillet and toss to coat evenly with sauce.
• If the mixture is too thick, loosen it with a splash of reserved pasta water.

4.6 Transfer to Baking Dish

• Pour everything into a greased baking dish.
• Sprinkle remaining cheese (and fried onions if using) on top for a crunchy layer.

4.7 Bake

• Bake at 350°F (175°C) for 20–25 minutes until the top is bubbly and golden.
• Let the casserole rest for 5–10 minutes before serving to help it set.

For a stovetop version, skip baking and serve straight from the skillet. More on this variation can be found at New South Charm.

Make‑Ahead, Storage & Reheating

• You can assemble the casserole up to 24 hours ahead and keep it in the fridge covered with foil or cling wrap.
• Alternatively, freeze the assembled (but unbaked) dish for up to 2 months—just thaw in the fridge overnight before baking.
• For leftovers, store portions in airtight containers:
  • In the fridge: up to 4 days
  • In the freezer: up to 2 months (freeze in individual servings for easier reheating)
• Reheating tips:
  • In the oven: Cover with foil and bake at 325°F until hot (add a splash of broth if dry).
