Heat olive oil in a skillet and cook chicken 5–6 minutes per side until golden and cooked through, then remove.
Add butter and garlic to the skillet and sauté 30 seconds until fragrant.
Stir in chicken broth and heavy cream and simmer 2–3 minutes.
Reduce heat and stir in Monterey Jack cheese until melted and smooth.
Return chicken to the skillet and spoon sauce over it.
