Steps
Before you start
- Use true steel cut (Irish) oats, not rolled or quick oats; cooking times differ greatly.
- Choose a heavy 3-quart saucepan with a lid so the porridge doesn't scorch or boil over.
- Measure the liquids first so you can add them all at once while the oats are toasting.
Toast the oats
- Melt the butter in the saucepan over medium heat.
- Add the steel cut oats and stir constantly for 2 minutes.

Ready when: Oats smell nutty and look slightly golden at the edges.
Tip: Don't walk away; toasted oats go from nutty to scorched quickly.
Add liquids
- Pour in the water and milk, add the salt, and stir.
- Raise the heat to high and bring to a boil, about 5 minutes.

Ready when: Large bubbles break across the whole surface.
Tip: Stay close; the milk can foam up and boil over.
Simmer gently
- Reduce the heat to low so the surface bubbles lazily.
- Partially cover the pot with the lid slightly ajar and cook for 20 minutes, stirring every 5 minutes and scraping the bottom.

Ready when: Oats are swollen and tender but still slightly chewy, and the porridge is thickened but still loose.
Tip: If it sticks or looks dry, stir in 2 tablespoons hot water.
Sweeten and rest
- Stir in the brown sugar until dissolved.
- Remove from the heat, cover, and let rest for 5 minutes; the porridge will thicken to a creamy, spoonable texture.

Ready when: Porridge mounds softly on a spoon and no sugar granules remain.
Tip: Taste before serving and add another teaspoon of sugar if you like it sweeter.
Serve
- Divide among 4 warm bowls.
- Pour a splash of extra milk over each and sprinkle with a little more brown sugar.

Tips
- Toasting the oats gives a deeper, nuttier flavor, so don't skip it.
- Stir only occasionally; constant stirring makes the porridge gluey.
- For a creamier result, use 2 cups water and 2 cups milk, but stir more often to prevent scorching.
- Add raisins, chopped apple, or a pinch of cinnamon in the last 5 minutes of simmering.
Make ahead
"Cook the oats through step 3 without the sugar, cool, and refrigerate up to 4 days. Reheat with a splash of milk, then sweeten."
Storage & reheating
"Room temperature: up to 2 hours. Refrigerator: airtight up to 4 days. Freezer: portion into containers up to 3 months. Reheat in a saucepan or microwave with 2–3 tablespoons milk or water per serving, stirring until hot and creamy."
Substitutions
- whole milk → oat milk or unsweetened almond milk. Makes it dairy-free; the texture will be slightly less rich.
- light or dark brown sugar → maple syrup or honey. Use 3 tablespoons (45 ml) and stir in at the end.
- unsalted butter → coconut oil or olive oil. Same amount; toasts the oats just as well.
