Orzo
Orzo is a small, rice-shaped pasta made from semolina wheat (or sometimes rice flour for gluten-free versions). Despite the nickname "orzo rice" and its rice-like appearance, it's pasta through and through, made the same way as spaghetti or penne, just extruded into a tiny grain shape. It cooks quickly, holds sauce well because of its shape, and works in everything from soups to cold salads to baked casseroles.
Varieties
Regular orzo and whole wheat orzo are the two common wheat-based versions; gluten-free orzo made from rice, corn, or lentil flour cooks faster and holds together less firmly, so it's easy to overcook into mush.
Buying tips
Check the ingredient list if avoiding wheat, since many brands sell rice-flour or corn-based orzo that looks identical on the shelf. Whole wheat orzo is slightly darker and takes about a minute longer to cook than regular semolina orzo.
Substitutes
Acini di pepe or ditalini pasta — 1:1
Same wheat pasta family; acini di pepe is smaller and rounder, ditalini slightly larger, but both cook in a similar amount of time.
Arborio rice — 1:1 by volume
Cooks starchier and creamier than orzo, closer to a risotto texture; good in soups but reduce liquid slightly since arborio absorbs more.
Couscous (regular, not pearl) — 1:1
Much faster cooking (about 5 minutes) and lighter in texture; best for salads rather than soups or baked dishes.
Pearl (Israeli) couscous — 1:1
Larger and chewier than orzo, but a close substitute in texture for salads and pilafs.
Long-grain white rice — 1:1 by volume
Needs more liquid and about twice the cooking time; works in soups but won't match orzo's tender bite.
Storage
Store uncooked orzo in a sealed container in the pantry for up to two years; it doesn't need refrigeration. Cooked orzo keeps in an airtight container in the refrigerator for 3 to 5 days, and benefits from a splash of water or olive oil when reheated since it dries out and clumps.
How to use
Boil in salted water for 8 to 10 minutes for al dente pasta salads, or cook it risotto-style by toasting in butter and gradually adding warm broth for a creamy side dish. It also thickens soups (like Greek avgolemono or minestrone) and works baked into casseroles with cheese, where it absorbs liquid as it bakes.
What it pairs with
Pairs well with lemon, feta, olive oil, and fresh herbs in Mediterranean-style salads, and with parmesan, butter, and mushrooms in creamy risotto-style preparations. Also a natural match for shrimp, chicken, and roasted vegetables.
Nutrition
Orzo is a wheat pasta, so it's primarily carbohydrate with a modest amount of protein (about 7 grams per cooked cup) and little fat. Whole wheat orzo adds more fiber; gluten-free versions made from rice or corn have a different nutrient profile and softer texture.
FAQ
Is orzo actually a type of rice?
No. Orzo is wheat pasta shaped to resemble rice grains. It's made and cooked like pasta, not rinsed or steamed the way rice is.
Why did my orzo turn mushy?
Orzo overcooks fast because of its small size and thin shape. Start checking for doneness at 7 minutes and drain as soon as it's al dente, since it keeps softening in residual heat.
Do you need to rinse orzo after cooking?
Rinse it only if using it cold in a salad, to stop the cooking and wash off surface starch that would otherwise make it clump. For hot dishes, skip rinsing so the starch helps sauce cling.
Can orzo be cooked risotto-style without pre-boiling?
Yes, toast the raw orzo in butter or oil first, then add warm broth a ladle at a time, stirring until absorbed, the same technique used for risotto, and it will turn creamy in about 10 to 12 minutes.
