One of the easiest ways to update white kitchen cabinets is by changing the hardware to more modern finishes such as matte black, brushed nickel, or gold. You can also create a more current look by adding features like open shelving, glass-front cabinet doors, or under-cabinet lighting. Pairing white cabinets with updated countertops, backsplash materials, or newer appliances can also help give the kitchen a more modern feel.
