Step 1: Rinse the rice under cold water until the water runs clear. This helps remove excess starch, though with Arborio, some starch is desired for creaminess.
Step 2: In a heavy-bottomed saucepan or Dutch oven, combine the rinsed rice, whole milk, granulated sugar, and salt. Stir well to combine.
Step 3: Bring the mixture to a gentle boil over medium heat, stirring frequently to prevent sticking. Once boiling, reduce the heat to low and simmer, uncovered.
Step 4: Continue to simmer for 25-30 minutes, stirring every 2-3 minutes to prevent the rice from sticking to the bottom of the pot. The rice should absorb most of the milk and become tender, and the pudding will thicken significantly.
Step 5: Once the easy rice pudding has reached a thick, creamy consistency and the rice is tender, remove the saucepan from the heat.
Step 6: Stir in the vanilla extract and ground cinnamon. Taste and adjust sweetness if desired.
Step 7: Serve warm or cold. Garnish with an extra sprinkle of cinnamon, fresh berries, or a dollop of whipped cream if desired. This easy rice pudding is best enjoyed fresh, but leftovers store well.
