Oatmeal

Steel-cut oats only. Rolled oats turn to mush in any sous vide bath because they're already partially cooked and the long bath dissolves them. Steel-cut oats are whole, raw groats that need long, slow hydration - exactly what sous vide is best at.

Use a 1:4 oats-to-liquid ratio. One cup of steel-cut oats to four cups of liquid (water, milk, or a mix). Less liquid and they come out gluey; more and they're soupy. The 1:4 ratio gives you creamy, distinct grains with just the right body.

Cook at 194°F for 2 h for breakfast-tomorrow timing. Bag the oats, liquid, salt, and any aromatics before bed and set the bath. Wake up to perfectly cooked, creamy oatmeal with zero stirring and zero risk of scorching or sticking.

Add fat to the bag, not at the table. A pat of butter, a splash of cream, or a spoonful of coconut oil goes into the bag at the start. The fat emulsifies into the cooking liquid and gives the finished oats a luxurious mouthfeel that you can't replicate by topping later.

Anti-tip: don't add brown sugar or maple syrup to the bag. The sugar will caramelize and stick to the bag walls in a way that's hard to scrape out. Add sweeteners after cooking, when the oats are in the bowl. Save the bag for savory aromatics like vanilla, cinnamon, or salt.

Shake jars immediately after cooking to distribute starch and keep oats creamy.

Add chia or flax seeds after the bath so they don’t thicken excessively during cooking.

Store jars without toppings for up to 5 days; add fruit/nuts when serving.

Line jars with parchment if you plan to unmold and slice.

Let oats cool fully before cutting so they hold their shape.

For sweet versions, stir chocolate chips or dried fruit after cooking so they stay intact.
