Cook the chicken.
Heat olive oil in a large pot over medium heat. Season chicken with salt and pepper. Cook 5–6 minutes per side until golden and cooked through (165°F / 74°C). Remove and rest.
Sauté aromatics.
In the same pot, add onion and cook for 2–3 minutes. Stir in garlic and cook for 30 seconds until fragrant.
Build the broth.
Pour in chicken broth and soy sauce. Bring to a gentle simmer.
Add cream.
Stir in heavy cream and reduce heat slightly. Let simmer 5–7 minutes.
Do not boil, or the cream may separate.
Cook noodles.
Add ramen noodles directly to the broth. Cook 3–4 minutes until tender.
Do not overcook, as noodles soften quickly.
Slice chicken and return to pot.
Slice rested chicken thinly and add back into soup.
Taste and adjust.
Add extra salt, pepper, or soy sauce if needed.
Taste before serving — balance is key.
