This simple, comforting dessert comes together on the stove using already-cooked rice. Whole milk, a touch of sugar, and a beaten egg create a silky base, while butter and vanilla added at the end bring everything together with a warm, cozy flavor.
Warm the rice. Place the cooked rice in a medium saucepan. Add 1 ½ cups of the milk and the salt. Cook over medium heat, stirring regularly, until the mixture thickens and becomes creamy, about 15–20 minutes.
Blend in the remaining ingredients. Stir in the remaining ½ cup of milk, the raisins, the beaten egg, and the sugar. Keep stirring as the mixture cooks for another 2–3 minutes, ensuring everything combines smoothly.
Finish with richness. Remove the pan from the heat. Add the butter and vanilla extract, stirring until the butter melts completely and the pudding becomes velvety.
Serve. Spoon into bowls and enjoy warm. A light sprinkle of cinnamon is a wonderful finishing touch if you like a hint of spice.
