Start by heating the olive oil in a large pot over medium heat. Watch as the oil shimmers, indicating it's ready for the next step.
Add in the chopped yellow onion and minced garlic. Sauté them until they become tender and fragrant, about three to five minutes. The onions should be translucent, adding a base of flavor to your soup.
Next, toss in the chopped celery. Let it cook with the onions and garlic for an additional two to three minutes until it softens slightly.
Now, it's time to add the star of our dish: the cooked and shredded chicken. Stir it in, allowing it to absorb the flavors of the sautéed vegetables.
Pour in the entire bag of frozen mixed vegetables. This is where the soup becomes colorful and vibrant. Stir everything together.
Add the pepper, cream of potato soup, and cream of chicken soup into the pot. Stir until everything is well combined, and the soups are melted.
Slowly add the milk, stirring continuously to achieve a smooth consistency. The mixture should begin to bubble gently.
Let the soup simmer for about five to seven minutes, stirring occasionally. You want everything to heat through and meld together, creating a deliciously creamy texture.
Once heated, carefully pour the soup into bowls. If you’ve chosen to make Grand biscuits, bake them according to the package instructions while the soup simmers.
To serve, top each bowl with a warm biscuit, if desired. Garnish with fresh parsley for a pop of color and freshness. Enjoy your homemade Easy Chicken Pot Pie Soup hot and hearty!
