One cup cooked pearled barley has about 3.5 g protein; one cup dry pearled barley has about 19.8 g, based on USDA-linked data.
Barley is a grain people add to soups, salads, bowls, and pilafs. If you’re counting protein, the serving and form decide the number you get. Below you’ll see the exact protein for a standard cooked cup of pearled barley, plus dry cup values and hulled vs. pearled notes. The short version: cooked barley is a modest protein source, while a dry cup packs more protein because it’s concentrated before boiling.
Barley Protein Per Cup — What One Cup Gives You
For everyday meals, most folks measure a finished cup of cooked barley. Using USDA-based references, a 1-cup cooked pearled barley serving (about 157 g) lands at roughly 3.5 g protein. If you measure dry grain in a cup before cooking, a 1-cup dry pearled barley serving sits near 19.8 g protein. The gap comes from water uptake during cooking, which lowers protein density per cup.
Barley Protein By Form And Serving
| Form | Serving | Protein (g) |
|---|---|---|
| Pearled, Cooked | 1 cup (~157 g) | ~3.5 |
| Hulled, Cooked | 1 cup | ~3.6 |
| Pearled, Raw (Dry) | 1 cup (dry) | ~19.8 |
| Pearled, Cooked | 100 g | ~2.3 |
| Pearled, Raw | 100 g | ~9.9 |
| Hulled, Raw | 100 g | ~12.8 |
| Pearled, Cooked | 1/2 cup | ~1.8 |
Numbers above come from USDA-linked datasets and clinical libraries. For cooked pearled barley, the protein value sits near 3.5 g per cup in multiple references that draw from USDA data.

Barley Protein Per Cup Guide: Cooked, Dry, Hulled
Let’s pin down what changes protein per cup:
Cooking Hydrates The Grain
As barley simmers, it absorbs water and swells. The protein grams don’t vanish; they spread through more volume. That’s why a cooked cup shows fewer grams than a dry cup. Think of it as dilution by water, not loss of amino acids.
Pearled Vs. Hulled
Pearled barley has its outer bran polished away. Hulled barley keeps the bran layer. Bran holds fiber and a small share of protein and minerals. On the plate, both cooked forms sit in the same ballpark for protein per cooked cup (about 3.5–3.6 g), with hulled edging up in fiber and some minerals in many datasets. The choice often comes down to texture and fiber goals.
Dry Cup Vs. Cooked Cup
A dry cup of pearled barley (~1 cup raw) can sit near 19–20 g protein because you have far more grain packed into that measuring cup. Once boiled, the same dry cup typically yields several cooked cups, so the protein per single cooked cup drops even though total protein in the pot stays the same.
Weight Matters For Precision
When a label lists “1 cup,” the weight behind that cup can vary by how firmly the grain is packed and by moisture. If you need precision, weigh the portion after cooking. The cooked reference of ~2.3 g protein per 100 g gives a clean path to scale your target intake.
How To Hit A Protein Target With Barley
Barley works best as a base you pair with higher-protein partners. A single cooked cup isn’t a protein star on its own, but it can pull its weight in a balanced bowl. Here are simple ways to reach numbers that fit a meal plan without losing barley’s chewy bite.
Smart Pairings
- Legumes: Add chickpeas, lentils, or edamame. A half cup of cooked lentils adds a solid bump and blends well in soups and stews.
- Dairy Or Soy: Crumbled feta, skyr, or grilled tofu brings up the total fast while keeping the bowl fresh.
- Eggs Or Fish: A poached egg over a warm barley salad or a canned salmon toss turns a side into a full plate.
- Nuts And Seeds: Toasted pumpkin seeds or chopped almonds add crunch and more protein per serving.
Serving Moves That Raise Protein
- Go From One To Two Cups: Two cups cooked pearled barley bring you to ~7 g from barley alone; the rest can come from toppings.
- Use Stock Rather Than Water: If you simmer the grain in a protein-fortified stock, the final cup may pick up small extra grams.
- Fold In Beans Post-Cook: A one-to-one mix of cooked barley and cooked beans gives a sturdy base with a clear protein lift.
Cooking Notes That Keep The Numbers Consistent
Cooking style can change the cup weight. Boil gently and drain well for repeatable results. A common kitchen ratio for pearled barley is 1 cup dry barley to about 3 cups liquid, simmered until tender with most liquid absorbed. This yields multiple cooked cups with the texture most recipes expect.
Portioning Tips
- Weigh Your Cup Once: Scoop a cup as you normally would, weigh it, and keep that weight as your personal cup reference for future logging.
- Stir Before Scooping: Scooping from the top can give a lighter cup; a quick stir evens out moisture for a more consistent measure.
- Note The Add-Ins: Oil, cheese, or sauces change calories and macros. Add those numbers after you tally the plain grain.
Protein Quality And Amino Acids
Like most cereal grains, barley’s protein skews lower in lysine and higher in methionine. That’s another reason a bean-and-barley pair works well at the meal level. You don’t need to micromanage amino acids in a single bowl, but mixing grains and legumes across a day gives a balanced pattern.
Fiber, Minerals, And Why People Still Pick Barley
The main draw isn’t protein; it’s fiber and texture. A cooked cup of pearled barley sits near 6 g fiber, with hulled landing higher in many cases. If you’re tracking fiber sources, see the federal chart that lists barley among fiber-dense foods. That same cup also contributes iron, magnesium, and selenium in steady amounts without adding much fat or sodium.
How Barley Stacks Up Against Other Grains (Cooked Cup)
Protein varies wildly by grain. Here’s a quick side-by-side so you can plan a bowl without hunting through labels. Values below come from USDA-based consumer nutrition libraries that summarize the same datasets.
Protein Per Cooked Cup: Common Grains
| Grain (Cooked) | Serving | Protein (g) |
|---|---|---|
| Pearled Barley | 1 cup | ~3.5 |
| Brown Rice | 1 cup | ~4.5 |
| Quinoa | 1 cup | ~8.0 |
| Kamut (Khorasan Wheat) | 1 cup | ~9.8 |
| Spelt | 1 cup | ~10–11 |
If you want a grain-first bowl with more protein per cup, quinoa and ancient wheat types sit higher. If the goal is fiber with a chewy base, barley earns its spot. Many cooks split the difference by doing a half-and-half mix of barley and a higher-protein grain or legume.
Practical Takeaways For Barley Protein Per Cup
- Cooked Cup Baseline: Use ~3.5 g protein per cup for pearled barley. This is the number most meal logs use for soups, salads, and sides.
- Dry Cup Snapshot: A dry cup of pearled barley sits near ~19.8 g protein, but it yields several cooked cups. Tally the cooked cups you actually eat.
- Hulled Vs. Pearled: Expect a small swing in protein per cup; fiber and mineral shifts are the bigger difference on the plate.
- Hit Your Target With Pairings: Add beans, tofu, eggs, dairy, fish, or nuts to bring the bowl to your protein goal.
- Weigh For Accuracy: If you track closely, weigh the portion. Use ~2.3 g protein per 100 g cooked for quick math.
Sources And Data Notes
This guide draws on USDA-linked nutrition tables and clinical library sheets. See cooked pearled barley, 1 cup for the 3.5 g protein figure and full panel, and pearled barley, raw for the 1-cup dry value near 19.8 g. A clinical nutrition library confirms the cooked cup numbers for pearled barley and lists the same macronutrient spread. A consumer nutrition overview that cites USDA provides the hulled cooked cup figure near 3.6 g. For fiber context, the federal food sources of fiber page lists barley among top sources.
Two closing lines to lock it in: if your tracking app asks for barley protein per cup, log ~3.5 g for cooked pearled barley and adjust by weight when you need precision. If a recipe lists a dry cup, split that pot into the cooked cups you plate and assign the barley protein per cup value to each serving.
