  • 1 large yellow onion, diced
  • 1 red bell pepper
  • 1 yellow bell pepper
  • 1 green bell pepper
  • 5 cloves garlic, minced
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 2 cups water

  • 1 (10-ounce) can Rotel tomatoes
  • 8 ounces penne pasta, dried
  • salt and fresh cracked pepper to taste
  • green onions, sliced for garnish

  • In a Dutch oven over medium heat, add 2 tablespoons of olive oil.

  • Add water, chicken base, heavy cream, Rotel tomatoes, garlic powder, onion powder, and penne pasta. Stir to combine. Bring liquid to a boil.
  • Once boiling, reduce heat to low. Then cover and allow to simmer until pasta is cooked, about 15 minutes. Stir occasionally.
  • Uncover and turn heat back to medium. Add chicken and vegetables back to the pot. Stir to combine. Let cook for 3 to 5 additional minutes.
  • Garnish with green onion, cilantro, salt, and fresh cracked pepper.
  • Serve and enjoy!


  • Chicken, onion, bell peppers, and garlic can all be pre-chopped and stored in airtight containers in the refrigerator until you are ready to make this recipe. Store the raw chicken in a separate container.
  • Make sure that the chicken pieces are a consistent size so that they all cook fully in about the same amount of time.
