When you want to estimate protein per meatball, the key is to convert your batch into a per-meatball weight, then multiply by a typical protein-per-100-gram value for cooked ground beef.

Step 1: Find the cooked weight per meatball

If your total cooked beef yield was 900 g and you made 9 meatballs, then each meatball contains:

900 g ÷ 9 = 100 g cooked beef per meatball

So each meatball is effectively 100 g of cooked ground beef, assuming the batch is evenly divided.

Step 2: Use a typical protein value for cooked ground beef

Cooked ground beef protein is usually around the mid-20s grams per 100 g. Exact protein depends a bit on the fat percentage (and the label you started with), but a practical estimate is:

• About 26 g protein per 100 g cooked ground beef

The result: protein per meatball

Because each meatball is 100 g cooked, your protein per meatball is approximately:

100 g cooked beef × (about 26 g protein per 100 g) = about 26 g protein

A realistic range

Depending on the fat ratio and the specific product, a reasonable range is:

• About 25 to 27 g of protein per meatball

What can change the number

Your protein per meatball will be lower if the meatballs include significant non-meat ingredients, such as breadcrumbs, oats, milk, or large amounts of onion. If you tell me what you added (and roughly how much), I can estimate a more accurate protein number for your exact recipe.
