In a medium saucepan, combine the old-fashioned oats, milk, water, maple syrup, cinnamon, kosher salt, and any optional additions like chia seeds or flaxseed. Stir well to mix all the ingredients together. The mixture should appear creamy as it combines and thickens.
Heat the saucepan over medium-high heat until the liquid reaches a low, gentle boil. This should take several minutes. You’ll notice the bubbles forming around the edges, signaling that it’s time to reduce the heat.
Once boiling, reduce the heat to a simmer. Watch as the oatmeal begins to cook down, absorbing the liquid. Stir the mixture occasionally to prevent it from sticking to the bottom of the pan.
Add the diced apple to the simmering mixture. Stir gently to incorporate the apple pieces, allowing them to soften and infuse their sweetness into the oats.
Continue simmering, stirring periodically, until the oatmeal is creamy and has absorbed most of the liquid, about six to eight minutes. You want a texture that's thick but not too dry. If it becomes too thick, add a splash more of milk.
Once the oatmeal is ready, remove the saucepan from the heat. Stir in the vanilla extract for an extra layer of flavor. The aroma of the vanilla will take this dish to another level.
While the oatmeal cooks, prepare the topping. Heat a medium skillet over medium-low heat and add the unsalted butter. Allow it to melt completely so it coats the pan.
Add the additional diced apple, maple syrup, cinnamon, and kosher salt to the skillet. Stir to combine and let cook, stirring occasionally, for about eight minutes. The apples should become soft and tender without turning mushy.
Once the topping is ready, taste it and adjust the sweetness, cinnamon, or salt according to your preference. This is the moment to ensure it’s just right for you!
Serve the oatmeal hot in bowls, topped with the sautéed apples and a sprinkling of chopped toasted pecans. Enjoy every spoonful of this heartwarming dish.
