Wash and peel the firm apples, core and slice them into wedges, about 1/4 inch thick. Squeeze lemon juice over the slices to prevent browning.

Melt the butter in a skillet over medium heat until bubbling, about 1-2 minutes.

Add the apple wedges to the hot skillet, sauté for 5-7 minutes until they soften and become lightly golden.

Sprinkle brown sugar and cinnamon over the apples, stir gently to coat, and cook for an additional 3-5 minutes until caramelized.

Remove from heat, transfer to a serving dish, and serve warm with optional toppings.
