Melt the butter in a skillet.
Add chicken chunks and onion. Cook, stirring often, until the chicken is cooked through and just starting to brown on the edges (about 5 minutes).
Stir in garlic and cook until fragrant (about 30 seconds).
Stir in hot sauce and cream, then gnocchi and oregano. Bring to a simmer and cook, stirring occasionally, for 3 minutes.
Serve hot either by itself or with a drizzle of ranch dressing on top.
