The best way to cook rolled oats
For one serving of old-fashioned rolled oats, simmer ½ cup oats in 1 cup water or milk for about 5 minutes, stirring occasionally. Stop when tender and loosen with a little liquid after resting.

The oat type comes first. Steel-cut pieces, quick oats, and old-fashioned flakes have different schedules. This guide is for ordinary old-fashioned rolled oats; extra-thick brands may need the package’s longer time. Choose a saucepan with room to stir without losing breakfast over the rim.

Before you start
- Use a deep microwave-safe bowl and keep it open; never seal it.
- Milk and porridge can bubble suddenly. Reduce heat if they climb the pan.
- Refrigerate perishable cooked oats within 2 hours, or 1 hour above 90°F.
Stovetop method
Measure before heating
Measure ½ cup oats separately from 1 cup liquid. Choose a pan with space above the liquid line.
Look for Room for the porridge to rise.
Bring the liquid to a boil
Heat water or milk with the optional salt. Stir milk as it warms; reduce heat if it starts climbing.
Look for An active but controlled boil.
Simmer the oats
Stir in the oats and cook around medium heat for about 5 minutes, stirring occasionally. Lower heat to prevent scorching.
Look for Tender flakes in creamy liquid.
5:00 suggested timingFinish in the bowl
Remove from heat and let the texture settle briefly. Add a spoonful of liquid if too thick. Cool a spoonful before tasting.
Look for Porridge flows from the spoon without a dry clump.
Fix common problems
Using a small cereal bowl in the microwave: the porridge expands before it settles.
Too thick? Stir in a tablespoon of liquid at a time after cooking.
Burnt bottom? Transfer the unburnt top without scraping; use lower heat next time.
Common questions about this method
Can I replace rolled oats with steel-cut oats?
Use the steel-cut package instructions. Cut groats need a longer cook and different liquid quantities than the flakes measured here.

MicrowaveAbout 5 min
Combine ½ cup old-fashioned rolled oats and 1 cup water or milk in a deep, open microwave-safe bowl, leaving ample room for bubbling. Heat on high for about 2½–3 minutes and stop if foam approaches the rim. Stir, add short intervals if needed for tenderness, and let settle before eating.
Preparation
1 bowl
Ingredients
- ½ cup old-fashioned rolled oats
- 1 cup water or milk
- Pinch of salt, optional
Equipment
- Deep microwave-safe bowl
- Spoon
- Measuring cups
- Oven mitts
Start with the manufacturer’s 2½–3 minute window; stop if it threatens to overflow.
Choose the bowl
Use a deep bowl with ample empty space. Combine oats, liquid, and optional salt.
Look for Mixture fills well under half the bowl.
Microwave and observe
Heat on high for 2½–3 minutes. Stay nearby and stop if foam approaches the rim.
Look for Flakes soften; bubbling stays contained.
Stir and adjust
Remove with mitts and stir. If flakes remain firm, add short heating intervals, stirring between them.
Look for No hard centers; liquid is distributed.
Let it settle
Let the bowl stand briefly, then thin with a little liquid if desired. Check temperature before eating.
Look for A warm spoonful, not a scalding one.
