In a large, heavy pan, melt butter until liquid and shiny on high.
Pat chicken thighs dry with a paper towel.
Generously season chicken thighs with salt and pepper.
Add chicken to pan and cook 3-4 minutes until one side is golden brown and crunchy. Flip and repeat for other side. Reduce heat to medium.
Add diced garlic to pan, stirring quickly to prevent burning.
Sprinkle lemon zest over chicken thighs.
When garlic is soft and fragrant (not burned), add oregano, lemon slices, and wine.
Cook until sauce has thickened and chicken thighs have reached 165 degrees internally.
Remove from pan and plate with grilled vegetables, topping with sauce. Also great to add to salads, wraps, tacos, or save for meal prep to reheat for lunch.
