Start by spraying the inside of your 6-quart or larger crockpot with non-stick cooking spray to prevent sticking. This simple step makes cleanup so much easier later.
Add all your ingredients to the crockpot - the milk, instant rice, white sugar, brown sugar, butter, vanilla extract, cinnamon, and salt. Give everything a good stir to combine, making sure the sugar dissolves and the butter is distributed evenly throughout.
6 Cups Whole Milk, 2 Cups Instant rice, ¾ Cup White Granulated Sugar, 2 Tablespoons Brown Sugar, 1 Tablespoon Salted Butter, 1 Teaspoon Vanilla Extract, 1 Teaspoon Cinnamon, ¼ Teaspoon Salt
Set your crockpot to low and cook for 4 hours, stirring occasionally every hour or so if you can. The rice will gradually absorb the liquid and the pudding will thicken as it cooks. Keep in mind that everyone likes their rice pudding at different consistencies, so you can stop cooking once the rice is tender and you've reached your preferred thickness.
When the pudding is done, you can garnish each serving with a sprinkle of ground cinnamon, a few raisins, or even a piece of cinnamon stick for presentation. Serve warm for the ultimate comfort food experience, or chill it in the fridge for a cool, creamy treat.
½ Cup Raisins, Extra Cinnamon, Cinnamon Sticks (optional garnish
Notes
Stir occasionally - While this is mostly a hands-off recipe, stirring every hour helps ensure even cooking and prevents any rice from sticking to the bottom or sides of the crockpot.
Adjust cooking time - If your pudding reaches your ideal consistency before the 4-hour mark, go ahead and turn off the crockpot. Conversely, if you prefer it thicker, you can cook it a bit longer.
Instant rice only - This recipe is specifically designed for instant rice, which cooks quickly and absorbs liquid properly in a slow cooker. Regular rice will not work and will remain hard and undercooked.
Layer of skin - Like any milk-based dessert, a skin may form on top as it cools. Simply stir it back in or remove it before serving, depending on your preference.
Taste and adjust - Before serving, taste your rice pudding and adjust the sweetness or spice if needed. You can always stir in a bit more sugar or cinnamon to suit your preferences.
