For a main course, plan 2.5 oz (about 70 g) of dry pasta per adult with a normal appetite. Side dishes need about 1.5 oz per person, and child portions are roughly 1 oz. Adjust up or down by about 1 oz for hearty or light eaters.
| Meal Context | Light | Normal | Hearty |
|---|---|---|---|
| Main Course (oz) | 1.5 | 2.5 | 3.5 |
| Side Dish (oz) | 1.0 | 1.5 | 2.0 |
| Child Portion (oz) | 0.75 | 1.0 | 1.5 |
Pasta roughly doubles in weight when cooked. Most shapes have a cooked multiplier between 1.9 and 2.25, meaning 1 oz dry becomes about 2 oz cooked. Orzo expands the most at 2.75 times its dry weight because it absorbs more water.
Use 1 quart (4 cups) of water for every 4 oz of dry pasta. Add 2 teaspoons of salt per quart of water. For a standard box of 16 oz pasta, you need 4 quarts (1 gallon) of water and 8 teaspoons of salt for properly seasoned pasta.
| Dry Pasta | Water (quarts) | Salt (tsp) |
|---|---|---|
| 4 oz (1 person) | 1 | 2 |
| 8 oz (3 people) | 2 | 4 |
| 16 oz / 1 box (6–7 people) | 4 | 8 |
| 32 oz / 2 boxes (12–14 people) | 8 | 16 |
Long thin pasta like spaghetti and linguine pairs best with light oil-based or thin tomato sauces. Short tubular shapes like penne and rigatoni catch chunky meat sauces. Wide flat noodles like fettuccine and farfalle hold creamy sauces well.
Cook pasta for 1–2 minutes less than the package directions for al dente texture. The pasta should be firm to the bite with a tiny white dot visible when you cut a piece in half. Always taste-test at the minimum cook time and drain immediately when ready.
