Old-Fashioned Rolled Oats Porridge with Milk
Creamy, tender-chewy porridge made the classic way: rolled oats simmered gently in milk and water with a pinch of salt, then finished with a little butter. Simple, comforting, and ready in about 15 minutes.

Steps
Before you start
- Use old-fashioned (regular) rolled oats, not instant or quick oats, and not steel-cut oats; cooking times differ.
- Choose a saucepan at least 2 quarts (2 L) so the milk has room to foam up without boiling over.
- Have your bowls and toppings ready, because porridge thickens quickly as it stands.
Combine and heat
- Add the oats, 1½ cups (360 ml) milk, ½ cup (120 ml) water and the salt to the saucepan.
- Stir once to combine.
- Set over medium heat and bring to a gentle simmer, stirring every minute or so, about 4 minutes.

Ready when: Small bubbles break around the edge and the surface just begins to tremble; the milk should not boil hard.
Tip: Starting the oats in cold liquid helps them release starch evenly for a creamier result and prevents clumps.
Simmer gently
- Reduce the heat to medium-low.
- Cook, stirring every 30 seconds or so and scraping the bottom and corners, for 5 to 6 minutes.

Ready when: Oats are tender but still slightly chewy, and the porridge is thick and creamy; a spoon dragged across the bottom leaves a trail that closes slowly.
Tip: If the milk climbs the pan, lift it off the heat for a few seconds and stir, then return it at lower heat.
Add butter and rest
- Remove the pan from the heat.
- Stir in the butter until melted.
- Cover and let stand for 2 minutes so the oats absorb the remaining liquid and the porridge thickens slightly.

Ready when: Porridge is spoonable and softly mounded, like thick yogurt.
Tip: If it gets too thick, stir in a tablespoon or two of hot water or milk.
Serve
- Divide the porridge between two warm bowls.
- Sprinkle each with 1 teaspoon brown sugar, if using, and pour 1 tablespoon cold milk around the edge.
- Serve right away.

Ready when: Steaming hot and creamy.
Tip: Taste before sweetening; a little extra pinch of salt often improves the flavor more than extra sugar.
Good to know
Tips
- Stir often but gently; over-stirring breaks down the oats and makes the porridge gluey.
- Salt is essential, and even a small amount brings out the nutty oat flavor.
- For a thicker porridge use 1⅓ cups (320 ml) total liquid; for a looser one use 2¼ cups (540 ml).
- Soak the pan right away; dried oats are hard to scrub.
Make ahead
Cook the porridge up to 3 days ahead, cool, and refrigerate in an airtight container; reheat with a splash of milk as described under storage.
Storage & reheating
Best eaten fresh. Refrigerate leftovers in an airtight container up to 4 days. Reheat in a saucepan over low heat or in the microwave in 30-second bursts, stirring in 2 to 3 tablespoons milk or water per serving to loosen. Freeze in single portions up to 2 months; thaw overnight in the fridge before reheating. Not recommended at room temperature for more than 2 hours.
Substitutions
- whole milk → 2% milk, or unsweetened soy or oat milk. Lower-fat milk gives a slightly less rich porridge; soy and oat milk work best among plant milks.
- unsalted butter → coconut oil or a drizzle of olive oil. Adds richness; coconut oil gives a faint sweet flavor.
- light brown sugar → maple syrup or honey. Use 2 teaspoons; stir in at serving.
- water → additional milk. Use 2 cups (480 ml) milk total for a richer, more dessert-like porridge.
