What you will need

This recipe uses 5 simple ingredients that you can find at any grocery store:

  • 0.5 cup old-fashioned rolled oats
  • 1 tsp ground cinnamon
  • 1 tbsp brown sugar
  • 0.125 tsp salt
  • 1 cup water

Step by step instructions

Step 1: Boil the Water

Bring 1 cup of water and a small pinch of salt to a boil in a small saucepan over medium-high heat. Using salted water enhances the natural nutty flavor of the oats.

Step 2: Cook the Oats

Stir in the rolled oats and reduce the heat to medium. Cook for 3 to 5 minutes stirring occasionally until the oats have absorbed most of the water and reached your preferred creamy or hearty consistency.

Step 3: Season and Serve

Remove from heat and stir in the ground cinnamon and brown sugar until fully combined. Transfer to a bowl and serve immediately, adding a splash of milk or a small pat of butter on top if desired.

Easy substitutions

Missing an ingredient? Here are some swaps that work perfectly:

  • old-fashioned rolled oats → quick oats for a faster cook time or steel-cut oats for more texture
  • brown sugar → maple syrup or honey for a different natural sweetness

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Cooking oats over too high heat which causes them to boil over and creates a gluey sticky texture
  • Adding the cinnamon at the start of cooking which can make it taste bitter instead of warm and sweet
