Main Ingredients

  • 12 oz dry spaghetti
  • 1.5 tbsp olive oil
  • 0.75 cup diced yellow onion
  • 0.75 cup diced green bell pepper
  • 1.5 tsp minced garlic
  • 21 oz condensed cream of chicken soup two small cans
  • 1.25 cup low-sodium chicken broth
  • 4 oz cream cheese, softened
  • 10 oz diced tomatoes with green chiles undrained
  • 2.5 cup shredded sharp cheddar cheese divided
  • 3 cup cooked shredded chicken rotisserie works great
  • 1.25 tsp kosher salt
  • 1 tsp black pepper
  • 0.5 tsp smoked paprika
  • 2 tbsp chopped fresh parsley for garnish

Instructions

Preparation Steps

  • Heat oven to 350°F. Mist a 9x13-inch baking dish with cooking spray.
  • Bring a large pot of salted water to a boil.
  • Cook spaghetti until just shy of al dente; drain and set aside.
  • Warm olive oil in a skillet over medium heat.
  • Sauté onion and bell pepper until tender, 5–6 minutes. Stir in garlic for 30 seconds.
  • Whisk in condensed soup, broth, and cream cheese until smooth and creamy.
  • Stir in tomatoes, 1.5 cups cheddar, salt, pepper, and paprika. Simmer 2 minutes.
  • Combine spaghetti, chicken, and sauce in a large bowl. Toss to coat evenly.
  • Spread mixture in the prepared dish. Top with remaining cheddar.
  • Bake until bubbly and lightly browned, 20–25 minutes. Rest 5 minutes.
  • Finish with parsley and serve warm.

Notes

Variation: Swap half the cheddar with Monterey Jack for extra melt. For heat, add a pinch of red pepper flakes. Storage: Refrigerate leftovers up to 4 days; reheat covered at 325°F with a splash of broth.
