Equipment

  • Pressure Cooker/ Air Fryer optional
  • Glass casserole dish

Ingredients
  

  • 1 whole chicken shredded
  • 1 pound spagetti noodles
  • 3 tablespoons butter
  • 1-2 poblano peppers (depending on size) seeded , small dice
  • 1 small onion small dice
  • 3 cloves fresh garlic minced
  • 1 teaspoon kosher salt
  • fresh cracked black pepper
  • 1 packet Hidden Valley Ranch seasoning mix
  • 2 tablespoons flour
  • 2 cups chicken stock
  • 1 can Rotel
  • 8 ounces Velveeta cheese cubed so it melts easier
  • ½ cup heavy cream
  • 4 ounces sharp cheddar cheese shredded
  • Optional: fresh parsley or cilantro for garnish chopped

Instructions
 

  • Preheat the oven to 400℉
  • Roast, peel, and dice the peppers. This is so simple to do in my Ninja Foodi 10-in-1 using the broil function.
    I just place the peppers in the air fryer basket, drizzle with a little olive oil, and set the broil function to 15-20 minutes. Flip about half way through.
  • Once they are charred all the way around, place them in a bowl and wrap them with plastic wrap. Allow the peppers to sweat for about 20 minutes. This makes them easy to peel.
    Remove the seeds and dice.
  • Add a generous amount of salt to a large pot of water and bring to a boil. Cook the spaghetti until it's al dente according to package directions.
    You want it to be a little firmer than usual because it will continue to cook in the oven.
  • In a large skillet, melt 3 tablespoons butter over medium heat. Add the diced onions. Season with a little salt and saute until the onions have softened (4-6 minutes). Add the minced garlic and cook for another 2 minutes or so.
    Add the roasted poblano and jalapenos.
  • Sprinkle 2 tablespoons of flour over the softened vegetables and stir to incorporate. Cook for one or two minutes.
    Now, slowly add 2 cups of chicken stock stirring with a whisk to keep the mixture from getting clumpy. Add 1 can of Rotel.
    Stir until the sauce starts to thicken.
    Add 8 ounces of cubed Velveeta cheese. Turn the heat down to medium-low and allow the cheese to melt, stirring occasionally, 6-8 minutes.
    Stir in ½ cup of heavy cream and simmer for a few more minutes. Taste for seasoning and adjust salt and black pepper at this point.
  • Add the cooked spaghetti and shredded chicken into the sauce and mix until everything has been combined.
    Pour it into a 9x12 glass casserole dish and top it with 8 ounces of shredded sharp cheddar cheese.
  • Bake it in the 400℉ oven for 10-15 minutes or until it starts to bubble and the cheese has melted on top.
  • Garnish with chopped cilantro or parsley if desired.
