Add the olive oil to a large heavy bottom stock pot and heat it up over medium heat for 1-2 minutes. Now gently add the diced onion into the pot and saute it for about 5 minutes until it begins to soften up.
Now add in the rotel tomatoes, the canned corn, black beans, and shredded chicken along with the room temperature cream cheese. Gently mix the cream cheese together with the other ingredients until it begins to melt, for about 3-5 minutes.
Now gently pour in the chicken broth and mix it until it is fully combined. The cream cheese should be fully incorporated. Add in all of your seasonings, including the taco seasoning, cumin, all purpose seasoning, and smoked paprika.
Mix the chicken taco soup very well, and then reduce the heat to a simmer and cover it with a lid. Allow it to simmer over medium low for 10-15 minutes while you prepare you soup toppings.
You can add shredded cheese, pico de gallo, sliced avocado, sour cream, salsa, or any taco toppings of your choice. Taste the soup for seasoning and add any additional salt and pepper or other seasoning that you think it may need. Serve right away with your favorite toppings, and enjoy!
