Prep the aromatics: Slice green onions, mince garlic, and dice celery.
If using raw chicken, cut into bite-size pieces and season lightly with salt and pepper.
Sauté the base: Heat olive oil and butter in a large pot over medium heat. Add the white parts of the green onions and celery. Cook 3–4 minutes until softened.
Stir in garlic and cook 30 seconds until fragrant.
Cook the chicken (if raw): Add the chicken to the pot and cook, stirring, until opaque and cooked through, 5–7 minutes. If using cooked chicken, wait to add it later.
Build the broth: Pour in chicken broth, soy sauce, and hot sauce. Start with 1/3 cup hot sauce if you prefer milder heat.
Bring to a simmer.
Add creaminess: Reduce heat to low. Whisk in cream cheese until smooth. Stir in heavy cream (or half-and-half).
Taste and adjust salt and pepper. The broth should be rich, spicy, and slightly tangy.
Cook the noodles: Add ramen noodles directly to the simmering broth. Cook 2–3 minutes until just tender.
Stir gently to separate the strands.
Add the chicken (if pre-cooked): Fold in shredded or diced cooked chicken and warm through for 1–2 minutes.
Finish and balance: Stir in rice vinegar for brightness. Adjust heat with more hot sauce or chili oil if you like. If the broth is too thick, splash in a little more broth or water.
Serve: Ladle into bowls.
Top with the green parts of the onions, celery slices, a drizzle of ranch or blue cheese dressing, crumbled blue cheese, and fresh herbs. Crack a little black pepper on top.
