Preheat the oven to 375°
In a large saucepan or Dutch oven, whisk together the flour, cream, and milk.
Add in the chicken broth, butter, salt, pepper, and ranch seasoning
Bring to a simmer, stirring frequently to prevent scorching, then reduce the heat to low
Let simmer until it thickens and no longer tastes like raw flour.
Once it has thickened, gently fold in the cooked chicken and add the gnocchi.
Cook for an additional 5-7 minutes, or until the gnocchi is tender and heated through.
Taste, and add any other desired seasonings
