A pot of rice or grains on Sunday is three or four dinners waiting to happen: a stir-fry, a grain bowl, a soup, a salad for lunch. It’s also the one leftover with a safety rule most people have never heard. Here’s how to cook a big batch of each grain the easy way, cool it fast, keep it and freeze it, and turn it into dinner all week.

An open freezer drawer with a clear bin of quart freezer bags frozen flat and standing upright like books.From No. 05Cook Once, Transform TwiceSame idea, smaller pot: cook the base once, freeze it flat, use it all week.

1 · Cook a big batchOne cup in, about three cups out.

Three hand-drawn measuring jugs each start with one cup of dry grain, then fill as it cooks: white rice to 3 cups, quinoa to 2¾ cups, and farro to about 3 cups.
Plan on about three times as much cooked as dry.

  1. Step 1: White rice · 30 min

    Rinse 2 cups long-grain rice in a strainer until the water runs almost clear. Bring it to a simmer with 3 cups water and ½ teaspoon salt, stir once, cover, and cook on low for 20 minutes. Take it off the heat and let it sit, covered, 10 minutes more, then fluff. Makes about 6 cups.

  2. Step 2: Brown rice, in the oven · 1 hr 10 min

    Spread 1½ cups brown rice in an 8-inch glass baking dish. Pour over 2⅓ cups boiling water with 2 teaspoons butter or oil and ½ teaspoon salt, cover tightly with a double layer of foil, and bake at 375°F for 1 hour. Fluff and let it rest 10 minutes. Doubling? Use a 9×13 dish; same time.

  3. Step 3: Quinoa · 30 min

    Rinse it unless the bag says prewashed. Toast 1½ cups quinoa in a dry saucepan until it smells nutty and pops, 5 to 7 minutes, then add 1¾ cups water and a little salt, cover and simmer on low 18 to 20 minutes. Let it rest 10 minutes. Box directions use almost twice the water; less water means fluffy, not soggy.

  4. Step 4: Farro (and other big grains) · 15–20 min

    Cook it like pasta: boil 1½ cups farro in 2 quarts salted water until tender with a little chew, 15 to 20 minutes, then drain well. Barley, wheat berries and brown rice all work this way too; just taste for doneness.

2 · Cool it fastThe rice rule nobody tells you.

Cooked white rice spread in a thin even layer on a rimmed aluminum baking sheet on an oak counter, with a wooden paddle and empty freezer bags beside it.
A thin layer on a sheet pan cools in minutes, not hours.

  1. Step 1: Spread it out

    Tip the hot rice or grains onto a rimmed baking sheet in a thin layer. It cools in a fraction of the time it would in the pot.

  2. Step 2: Portion it

    Move it into shallow containers, no more than 3 inches deep, or into freezer bags. A big deep tub stays warm in the middle for hours.

  3. Step 3: Into the fridge

    Within 2 hours of cooking. You don’t need to wait until it’s cold; just leave the lids cracked until it is.

3 · Keep itFour days in the fridge. Months in the freezer.

Quart freezer bags of cooked rice, quinoa and farro pressed flat into neat slabs, labeled with masking tape and stacked on an oak counter.
Pressed flat, they freeze fast, stack like books and thaw in minutes.
  • ✓

    Fridge: 3 to 4 days — Covered, in shallow containers. Past day 4, freeze what’s left.

  • ✓

    Freezer: about 2 months — Cool it on the sheet pan, then pack it into freezer bags, squeeze out the air, press flat and label. It’s best within about 2 months.

  • ✓

    Reheat to steaming — Sprinkle on 1 to 2 tablespoons of water per cup, cover, and heat until it’s steaming hot all the way through, 165°F.

4 · Use it all weekFried rice, grain bowls and salads.

A large nonstick skillet of vegetable fried rice with scrambled egg, peas, carrot and scallions on a gas burner, a wooden spoon in the pan and a small bowl of soy sauce beside it.
Cold, day-old rice is what makes fried rice work.

Fried rice for 4. Day-old rice from the fridge is perfect: chilled rice firms up, so the grains stay separate instead of turning to mush. Scramble 3 eggs in a little oil in a big skillet over medium-high heat and set them aside. Cook 1 diced carrot and ¾ cup diced ham (or any leftover meat) for a few minutes, add the white parts of 4 sliced scallions and another spoonful of oil, then 4 cups cooked rice, pressing and stirring until the clumps break up and it’s heated through, 2 to 5 minutes. Stir in ½ cup frozen peas, the eggs and the scallion greens, and season. (Brown rice can go in fresh; it doesn’t clump.) More egg ideas in No. 16.

A wide stoneware bowl of farro salad with cherry tomatoes, cucumber, parsley, crumbled feta and a lemon wedge, with a small jar of vinaigrette beside it.
Farro holds its chew for days, so it’s made for lunches.

Grain salad

Toss cooled farro, quinoa or brown rice with a lemony vinaigrette (3 tablespoons lemon juice, a spoonful of minced shallot, a little Dijon, ⅓ cup olive oil), then whatever’s in the crisper: tomatoes, cucumber, herbs, a handful of greens and some cheese. Cooling the grains on a sheet pan keeps them from going sticky.

Grain bowls

Warm grains, a protein, a roasted or raw vegetable and a sauce. It’s the easiest way to use up the bits from the week (see the plan in No. 08).

In soup

Stir a cup of cooked rice or barley into soup in its last few minutes, just long enough to heat through.

5 · The dry bagWhite rice keeps for years. Brown rice doesn’t.

  • W

    White rice: about 2 years — Sealed, in a cool, dry cupboard.

  • B

    Brown rice: about 6 months — Brown rice keeps its bran, which has natural oils that go stale and rancid. If it smells musty or oily, it’s past its best. Keep it in the fridge or freezer and it lasts about a year.

  • Q

    Quinoa: 2 to 3 years — In a sealed container, somewhere cool and dry.

  • F

    Farro and barley: about 6 months — Whole grains like these keep about 6 months in the pantry, or a year in the freezer.
