Place a Dutch oven or a large pot over medium-high heat. Add in olive oil. Then, add in chicken breasts and cook for around 10 minutes, flipping the chicken midway until it cooks through.
Remove the chicken from the pot and set aside.
Add the button and Bella mushrooms into the pot and sauté for 6 minutes or so. Reserve some of the cooked mushrooms for garnish.
Add in the onion, garlic, thyme, Marjoram, and grape juice. Sauté for 5 minutes or so.
Now, pour in the chicken broth and bring to simmer. Then, add the chicken back into the pot, stir the pot, and simmer for around 10 minutes uncovered.
Add cream cheese, Parmesan, and cheddar and whisk to mix well.
Pan-fry the mushroom you set aside, if any, before using it as garnish.
Garnish with the mushroom, cheddar cheese, and fresh parsley.
