Ingredients

  • 8 ounces uncooked spaghetti
  • 1 tablespoon olive oil
  • 1 tablespoon butter
  • 1/2 medium onion chopped finely
  • 1/2 green or red bell pepper chopped small
  • 2-3 cloves garlic minced
  • 2 tablespoons flour
  • 1/2 cup chicken broth
  • 1 cup heavy/whipping cream
  • 1 (10 fluid ounce) can Rotel Diced Tomatoes & Green Chilies with juices
  • 1/2 tablespoon chili powder
  • 2 cups shredded sharp cheddar divided
  • 2 cups shredded cooked chicken (I used rotisserie)
  • Salt & pepper to taste

Instructions

  • Preheat your oven to 350F and move the rack to the top third of the oven.
  • Boil a salted pot of water for the spaghetti and cook it 1 minute less than the package directions indicate. Meanwhile, prep all the recipe ingredients.
  • Drain the spaghetti then add it to a greased 9x13 casserole dish.
  • Add the oil and butter to a skillet over medium-high heat. Once it's hot, add the onions and peppers and sauté for 5 minutes.
  • Stir in the garlic and cook for 30 seconds.
  • Stir in the flour and cook for 1 minute (keep stirring).
  • Whisk in the chicken broth and cream and ensure there's no flour lumps.
  • Stir in the Rotel and chili powder. Let the sauce cook for 3-4 minutes (it should be slightly thickened, but don't let it get too thick!).
  • Turn the burner off and stir in half of the cheddar.
  • Stir in the chicken and add a bit of salt & pepper.
  • Transfer the skillet contents to the baking dish and toss with the spaghetti.
  • Top with the remaining cheddar and cover the casserole dish with foil. Bake for 25 minutes. Uncover and broil for a few minutes if you wish to brown the cheese.

Notes

  • Makes about 6 adult-size portions. It'll feed more if kids are eating or if you serve it with something like a salad and/or breadsticks on the side.
