Farro is a whole grain. It belongs to the wheat family and has been cultivated for thousands of years, making it one of the oldest grains in the human diet. The Whole Grains Council officially recognizes farro as a qualifying whole grain when it retains all of its bran, germ, and endosperm. But there’s an important catch: the form of farro you buy at the store determines whether you’re actually getting a whole grain or a partially refined one.
What “Whole Grain” Means for Farro
A grain counts as whole when all three original parts remain intact: the fiber-rich outer bran, the nutrient-dense germ, and the starchy endosperm. Farro in its unprocessed state checks all three boxes. The term “farro” actually refers to several ancient wheat species, most commonly emmer, but also einkorn and spelt. All three qualify as whole grains in their intact form.
In U.S. grocery stores, though, farro is sold in three different processing levels, and only one is truly a whole grain:
- Whole farro retains the full bran layer, delivering the most fiber and nutrients. It requires the longest cooking time.
- Semi-pearled farro has some bran removed, which shortens cooking time but also strips away a portion of the fiber and nutrients.
- Pearled farro has most of the bran removed. It cooks the fastest but contains less fiber and no longer qualifies as a whole grain.
If getting a true whole grain matters to you, check the packaging carefully. Labels don’t always specify the processing level, and “farro” on its own doesn’t guarantee the bran is intact. Look for the word “whole” on the ingredient list or a Whole Grain Stamp from the Whole Grains Council. Products carrying the 100% Whole Grain Stamp must contain at least 16 grams of whole grain per serving, with all grain ingredients being whole.
Nutritional Profile of Farro
One cooked cup of farro delivers roughly 200 calories, 7 grams of protein, and 7 grams of fiber. That protein content is notably higher than brown rice or quinoa on a per-serving basis, making farro a solid plant-based protein source. The 7 grams of fiber covers about a quarter of the daily recommended intake for most adults.
Like other whole grains, farro contains plant compounds called lignans. These are found throughout the bran and germ layers, which is exactly why processing level matters. Diets rich in lignan-containing foods (whole grains, nuts, seeds, legumes, fruits, and vegetables) have been consistently linked to lower cardiovascular disease risk. One large study following over 7,000 older adults for about four years found that those with the highest lignan intake had a 49% lower risk of cardiovascular events compared to those with the lowest intake. Lignans also show antioxidant activity in lab studies, though researchers are still working out how much of that effect translates directly to the human body versus coming from the broader nutrient package of whole grain foods.
Farro also has a chewy, nutty texture that holds up well in soups, salads, and grain bowls. It doesn’t turn mushy the way some grains do, which is part of why it’s become a staple in Mediterranean and Middle Eastern cooking.
Farro Contains Gluten
Because farro is a type of wheat, it contains gluten. This applies to all three species sold under the farro name: einkorn, emmer, and spelt. None of them are safe for people with celiac disease, non-celiac gluten sensitivity, or a wheat allergy. No amount of processing or cooking removes the gluten from farro. If you need a gluten-free whole grain, options like brown rice, quinoa, millet, buckwheat, and sorghum are better choices.
How Processing Affects Cooking Time
The tradeoff with whole farro is time. Whole farro can take up to 40 minutes to cook. Semi-pearled farro lands in the 20 to 30 minute range. Pearled farro is ready in 10 to 20 minutes. All three types benefit from a quick rinse under cold water before cooking, but none strictly require soaking.
A good middle ground for busy weeknights is semi-pearled farro. It still retains some of its bran, so you get more fiber and nutrients than the pearled version, while cutting the cooking time nearly in half compared to whole. If you batch-cook grains on the weekend, though, whole farro is worth the extra time. It stores well in the refrigerator for four to five days and reheats without losing its signature chewy texture.
How Farro Compares to Other Whole Grains
Farro’s combination of 7 grams each of protein and fiber per cup puts it in the upper tier of commonly available whole grains. Brown rice, by comparison, typically offers around 5 grams of protein and 3 to 4 grams of fiber per cooked cup. Quinoa is comparable in protein but lower in fiber. Barley comes close in fiber but falls slightly behind in protein.
Where farro really stands out is versatility and texture. It absorbs dressings and sauces well without falling apart, making it a natural fit for cold salads, warm pilafs, and hearty soups. Its slightly nutty flavor pairs well with roasted vegetables, fresh herbs, and sharp cheeses. For anyone looking to diversify beyond rice and oats, farro is one of the most approachable ancient grains to start with, as long as you choose the whole or semi-pearled variety and don’t need to avoid gluten.
