How many calories are in pasta?
Cooked pasta is about 155 kcal per 100 g (3.5 oz). Dry, the same pasta is about 360 kcal per 100 g, because cooking mostly adds water. Mixing the two up is the commonest pasta logging error there is.
Per portion
| Portion | Calories | Protein | Carbs | Fat |
|---|---|---|---|---|
| 100 g (3.5 oz) dry | ~360 kcal | 12 g | 73 g | 1.5 g |
| 100 g (3.5 oz) cooked | ~155 kcal | 5.5 g | 31 g | 0.9 g |
| 75 g (2.6 oz) dry, one standard serving | ~270 kcal | 9 g | 55 g | 1.1 g |
| 180 g (6.3 oz) cooked, the same serving | ~280 kcal | 10 g | 56 g | 1.6 g |
| 250 g (9 oz) cooked, restaurant plate | ~390 kcal | 14 g | 78 g | 2.3 g |
| 125 g (4.4 oz) fresh egg pasta, raw | ~350 kcal | 13 g | 65 g | 3.5 g |
What changes the number
Dry weight against cooked weight, first. Dry pasta takes up a little over twice its weight in water: 100 g dry comes off the hob at 220–250 g. Weigh it dry and log it as cooked and you understate the plate by 200 kcal. Packet panels almost always quote the dry figure, so check which weight a label means. It is the same trap as dry versus cooked rice, where the multiplier is nearer three, and as noodles.
Then the sauce, which usually wins. Per 150 g serving:
| Sauce | Approx. kcal |
|---|---|
| Tomato or passata based | ~90–130 |
| Pesto, 2 tbsp (30 g) | ~160–180 |
| Bolognese, beef | ~250–350 |
| Cheese sauce, as in macaroni cheese | ~350–450 |
| Carbonara | ~350–500 |
| Cream or Alfredo | ~400–550 |
A 75 g dry serving with tomato sauce is a 380 kcal dinner; the identical pasta under cream sauce is 750. That one choice moves more than any sensible change to the portion.
The extras. A tablespoon of olive oil in the pan is about 120 kcal, 20 g of grated parmesan about 80, a slice of garlic bread 110–150. Shape barely matters: spaghetti, penne and fusilli are within a few per cent of each other.
Where it fits in a deficit
At 155 kcal per 100 g cooked, pasta sits mid-range: above potato, below bread, close to rice, and well below pizza at around 265, which is the same flour with the water baked out. It is moderately filling but not high-volume food, and low in protein for the calories.
In a calorie deficit pasta rarely needs replacing — it needs weighing dry once, 75 g for most people, and then remembering what that looks like in your own bowl. After that the leverage is all in the sauce: a tomato base with 150 g of chicken or beans, and vegetables bulking out the sauce rather than more pasta, is a 500–600 kcal plate with real protein. The same bowl on cream and cheese is 900 and no more filling.
The “healthier pasta” aisle
Wholewheat pasta is not lower in calories. Cooked, it is 130–150 kcal per 100 g against 155 for white — a rounding error. The case for it is fibre, not energy.
Legume pasta is not lower either. Chickpea, lentil and pea pastas are 340–360 kcal per 100 g dry, the same as wheat. What they do offer is protein: 20–25 g per 100 g dry against 12 g, a real advantage at roughly zero calorie cost. Buy them for that, not for a saving that is not there.
Konjac and shirataki are the exception. At 10–20 kcal per 100 g they really are nearly free, being mostly water and fibre. They also do not behave like pasta, and bring no protein of their own.
