Equipment

  • Large Pot
  • Small bowl
  • Wooden Spoon
  • Chef’s knife
  • Cutting board

Ingredients
 

  • 2 tablespoons chili powder
  • 1 tablespoon cumin
  • 2 teaspoons salt
  • 1 teaspoon onion powder
  • 1 teaspoon garlic powder
  • 1 teaspoon Mexican oregano
  • 1.5 pounds chicken breasts cut into strips
  • 2 tablespoons olive oil divided
  • 1 red onion peeled and cut into 1/2-inch wedges
  • 4 cloves garlic minced
  • 1 cup chicken broth
  • 1 cup salsa
  • 4 cups milk
  • 1 pound penne pasta
  • 1 red bell pepper cut into 1/2-inch strips
  • 1 green bell pepper cut into 1/2-inch strips
  • 1 yellow bell pepper cut into 1/2-inch strips
  • 4 cups shredded Mexican 4-cheese blend
  • 0.25 cup minced cilantro

Instructions
 

Build the seasoning and start the sear

  • Stir together the chili powder, cumin, salt, onion powder, garlic powder, and Mexican oregano in a small bowl. Coat the chicken strips with half of this spice blend, reserving the other half for the end.
  • Heat 1 tablespoon of olive oil in a large pot over medium-high heat. Add the chicken in a single layer and sear for about 5 minutes until browned, avoiding the urge to stir constantly.
  • Remove the browned chicken to a plate and set aside, leaving the flavorful browned bits (the fond) in the pot.

Sauté, then deglaze for depth

  • Add the remaining tablespoon of olive oil to the pot. Sauté the red onion wedges and minced garlic for about 2 minutes until fragrant and the onions just begin to soften.
  • Pour in the chicken broth and salsa. Scrape the bottom of the pot with a wooden spoon to release all the browned bits into the liquid.

One-pot simmer and the cream cheese emulsification method

  • Stir in the milk and dry penne pasta. Add the chicken and the bell pepper strips back into the pot, then bring the mixture to a boil.
  • Reduce the heat to a light simmer. Cook for approximately 20 minutes, stirring every few minutes to ensure the pasta hydrates evenly and stays submerged.
  • Stir in 4 ounces of room-temperature cream cheese until it fully melts, creating a smooth and glossy sauce. If the sauce becomes too thick, loosen it with a splash of broth.

Cheesy finish and final seasoning

  • Add the remaining seasoning blend and the shredded Mexican cheese. Stir until the cheese is completely melted and the sauce is cohesive.
  • Garnish with minced cilantro and serve immediately while hot and creamy.

Notes

Silky Sauce Secret: Using room-temperature cream cheese is a vital emulsification step that stabilizes the dairy and ensures your sauce remains glossy without splitting.
Texture Control: To achieve a restaurant-style finish with the vegetables, consider sautéing only half the peppers at the start and adding the remaining half during the final simmer for a crisp-tender bite.
Storage & Reheating: This dish is best enjoyed within 3 days. When reheating, add a splash of milk or broth and warm gently over low heat to restore the velvet-like coating of the sauce.
