Peel and slice the peaches and set aside.
Spread ricotta cheese evenly over one side of each bread slice if using.
Layer sliced peaches on two bread slices.
Drizzle honey evenly over the peaches.
Place white cheddar cheese slices on the remaining bread slices.
Close the sandwiches with the cheese side facing the peaches.
Spread butter over the outside of each sandwich.
Heat a skillet or panini press over medium-low heat.
Place the sandwiches onto the heated surface.
Cook for 3–5 minutes per side, or until the bread is golden brown and the cheese is melted.
Reduce the heat if the bread browns too quickly before the cheese melts.
If using turkey bacon, fresh basil, or balsamic glaze, carefully open the sandwich after cooking and add the desired toppings.
Serve the Honey Peach White Cheddar Grilled Cheese Sandwich immediately while warm and melty.
