Yield in cooking refers to the usable amount of food you end up with after preparation or cooking. It can mean two different things depending on context: the number of servings a recipe produces (“yields 8 servings”) or the percentage of an ingredient that remains after you trim, peel, or cook it. The second meaning is especially important when you’re scaling recipes, budgeting for groceries, or figuring out how much raw food to buy for a specific number of people.
Recipe Yield vs. Ingredient Yield
When a recipe says “yield: 4 servings,” it simply tells you how much finished food you’ll get. This is the everyday meaning most home cooks encounter. If you need to feed 12 people instead of 4, you triple the recipe.
Ingredient yield is more technical. It answers the question: if you buy a pound of something, how much of that pound actually ends up on the plate? A pound of whole watermelon, for example, gives you only about 0.61 pounds of edible fruit once you remove the rind. A pound of whole apples yields roughly 0.78 pounds after peeling and coring. This gap between what you purchase and what you serve is the core concept behind yield percentages.
As Purchased vs. Edible Portion
Professional kitchens use two terms constantly: As Purchased (AP), which is the weight of an ingredient when you buy it, and Edible Portion (EP), which is the weight after trimming, peeling, deboning, or cooking. The yield percentage is just the edible portion divided by the as-purchased weight, multiplied by 100.
So if you start with 5 pounds of carrots and end up with 4 pounds after peeling and trimming the ends, your yield percentage is 80%. That means every time you need a specific amount of prepped carrots for a recipe, you know to buy about 25% more than the recipe calls for.
This math matters most when you’re cooking for a crowd. If you need 5 pounds of peeled, trimmed broccoli and you know that fresh untrimmed broccoli yields about 81% of its purchased weight, you’d divide 5 by 0.81 to learn you need roughly 6.2 pounds from the store.
How Much Meat You Lose to Cooking
Meat shrinks when it cooks because heat drives out moisture and renders fat. The USDA has documented cooking yields for dozens of cuts, and the range is wider than most people expect.
Beef tenderloin steak retains about 80% of its weight when grilled, while a beef brisket drops to around 69% after braising. Ground beef patties land somewhere in between: lean ground beef (under 12% fat) holds about 73% of its weight, while higher-fat patties (over 22% fat) shrink to roughly 69%. The fattier the meat, the more weight it loses as that fat renders out.
Pork follows a similar pattern. A cured boneless ham holds onto about 96% of its weight when roasted because it’s already been processed, but a fresh pork leg roast drops to 73%. Bone-in pork chops pan-fried retain about 76%. Chicken breast comes in at roughly 77% after poaching or simmering.
If you’re planning a dinner and want each guest to have 6 ounces of cooked chicken breast, you need to start with close to 8 ounces raw per person.
Why Cooking Method Changes the Yield
The same cut of beef can yield very different amounts depending on how you cook it. A USDA study tested this across dozens of cuts sourced from six locations around the country. Chuck and tenderloin roasts (larger pieces cooked in the oven) had higher yields and retained more moisture compared to steaks from the same cuts cooked on a grill. The logic is straightforward: a larger piece of meat has less surface area relative to its volume, so less moisture escapes.
Interestingly, the pattern reversed for some cuts. Bone-in ribeye roasts yielded only about 77% of their starting weight, while ribeye steaks came in at 85%. Fat content and the structure of the cut play a role here, since ribeye roasts rendered more fat during the longer cooking time.
Temperature matters too. The roasts in that study were cooked to an internal temperature of 140°F, while the steaks were taken to 158°F. Higher internal temperatures generally mean more moisture loss, but the size and fat distribution of the cut can override that effect.
Yield for Grains, Pasta, and Legumes
Grains and pasta work in the opposite direction from meat and vegetables. Instead of shrinking, they absorb water and expand. One pound of dry pasta produces roughly 2.66 pounds cooked. Dry couscous yields about 2.55 pounds. Amaranth nearly triples, going from 1 pound dry to 2.70 pounds cooked, and buckwheat expands even more, reaching about 3.06 pounds.
This expansion is why recipes often specify dry weight for grains rather than cooked weight. If a recipe calls for “1 cup of rice,” it almost always means dry, and you can expect to get about 3 cups cooked. Knowing these ratios keeps you from making far too much or too little.
How to Run a Yield Test at Home
Professional kitchens perform formal yield tests to control costs. The Culinary Institute of America outlines a simple process that works just as well in a home kitchen:
- Weigh the ingredient as purchased. This is your starting number, including peels, stems, bones, or fat.
- Prepare the ingredient the way you normally would: peel, trim, debone, or remove seeds.
- Weigh the prepped ingredient. This is your edible portion.
- Divide the prepped weight by the original weight. Multiply by 100 to get your yield percentage.
One detail worth noting: when butchering meat, the trim (bones, fat caps, scraps) still has value for making stock or rendering. Vegetable trim, in most cases, goes to the compost. This distinction matters for professional kitchens tracking food costs, but it also means your beef bones and chicken carcasses can offset the yield loss if you use them.
Common Yield Percentages Worth Knowing
A few numbers are useful to keep in your head when shopping. Whole watermelon yields 61% edible fruit. Apples yield 78% after peeling and coring. Broccoli yields 81% after trimming. Fresh fish fillets yield about 70% of their raw weight after cooking, which is one of the steepest losses in the kitchen.
Ground beef patties lose roughly a quarter to a third of their weight. Chicken breast loses about a quarter. Cured ham barely shrinks at all. And dry pasta roughly two-and-a-half-times its weight in cooked form.
These numbers won’t be exact every time, since ripeness, freshness, fat content, and your specific cooking setup all introduce variation. But they give you a reliable baseline for planning meals, especially when you’re feeding a specific number of people and don’t want to come up short.
