🍴 Ingredients

  • 1 lb Spaghetti, broken in half
  • 3 cups Cooked chicken, shredded (Rotisserie is perfect)
  • 4 tbsp Butter
  • 1 Bell pepper (Red or Green), finely diced
  • 1 Small yellow onion, finely diced
  • ¼ cup All-purpose flour
  • 2 cups Chicken broth
  • 1 cup Heavy cream or Half-and-half
  • 1 can (10 oz) Rotel (Diced tomatoes with green chilies), drained
  • 3 cups Sharp Cheddar cheese, shredded (divided)
  • 1 tsp Garlic powder & ½ tsp Onion powder
  • Salt and Black Pepper to taste

👩‍🍳 Instructions

1. The Under-Boil

  • Preheat your oven to 175°C (350°F).
  • Boil the spaghetti in salted water for about 7 minutes. Drain and set aside in a large mixing bowl.

2. The Veggie Base

  • In a large skillet or Dutch oven, melt the butter. Sauté the onion and bell pepper until soft and fragrant (about 5 minutes).

3. The “Liquid Gold” Sauce

  • Sprinkle the flour over the sautéed veggies and whisk for 1 minute.
  • Slowly pour in the chicken broth and heavy cream, whisking constantly until the sauce thickens and bubbles.
  • Stir in the garlic powder, onion powder, and the drained Rotel.
  • Remove from heat and stir in 2 cups of the Cheddar cheese until melted.

4. The Big Mix

  • Pour the cheese sauce over the cooked spaghetti in the large bowl. Add the shredded chicken and toss until every strand is coated.
  • Transfer to a greased 9×13 inch baking dish. Top with the remaining 1 cup of Cheddar.

5. The Bake

  • Bake for 25–30 minutes until the cheese on top is bubbly and just starting to brown at the edges.

The “Crunchy” Topping: If you want to take this to the next level, mix ½ cup of crushed Ritz crackers with 2 tablespoons of melted butter and sprinkle it over the cheese before baking. It adds a buttery snap that perfectly offsets the creamy interior.
