01 - Place a dry skillet over medium heat. Add the sliced almonds and toast, stirring frequently, until golden brown and fragrant, approximately 2 to 3 minutes. Remove from heat immediately and set aside for later use.
02 - In a medium saucepan, combine the rolled oats, milk, ground cinnamon, and salt. Place over medium heat and bring to a gentle boil, stirring occasionally to prevent sticking.
03 - Reduce the heat to low. Add the raisins and allow the mixture to simmer, stirring frequently, until the oats become creamy and tender, approximately 5 to 7 minutes. The mixture should thicken nicely during this process.
04 - Stir in the maple syrup or honey until fully incorporated. Remove the saucepan from heat.
05 - Divide the warm oatmeal between serving bowls. Top generously with the toasted almonds. If desired, add a pat of butter or vegan alternative and any additional toppings. Serve immediately while hot for the best texture and flavor.
