Calories and protein in a plate of pasta al pomodoro, with and without olive oil
Also called tomato pasta, spaghetti with tomato sauce.
The short answer
1 plate, about 360 g, normal olive oil
420 kcal
13 g protein
Fat 9.5 g · carbs 71 g · fibre 6.5 g · Vegan
Portion: 85 g of dry pasta, cooked, with sauce. Calculated from USDA FoodData Central
Weighing dry pasta before it goes in the pot is the single most useful habit for pasta nights.
With and without olive oil
The same 1 plate, changing only the olive oil in the sauce. Normal is about 7.5 g in this portion. A little halves the recipe’s fat and a lot doubles it, so in a portion of the same weight a lot comes out a little under double. These are the four levels the app asks about, with the same numbers.
| Olive oil | Added | Calories | Protein |
|---|---|---|---|
| None | 0 g | 360 kcal | 13 g |
| A little | 4 g | 390 kcal | 13 g |
| Normal | 7.5 g | 420 kcal | 13 g |
| A lot | 15 g | 470 kcal | 13 g |

The recipe behind these numbers
Raw ingredient weights in one 1 plate, scaled from the batch recipe in the Homekcal app’s dish table, with normal olive oil. Water, salt and spices add almost no energy but are listed so the recipe is complete. If your version has more of something, the numbers move with it.

What we could not match
Stand ins and assumptions in this recipe that a person still has to check.
- Cooked yield is an estimate of a typical home pot (water evaporated); a weighed batch would replace it.
- Basil is left out (negligible energy); parmesan on top is not included and should be logged on its own.
How this was worked out
This is the same dish the Homekcal app logs, from the same table. Each raw ingredient’s weight is multiplied by its per-100 g values in USDA FoodData Central, the batch is added up and divided by the cooked weight it makes. Calories are rounded to the nearest 10 and grams to the nearest gram, because a standard recipe is not your recipe. These are calculated values, not weighed or lab tested meals, and home versions vary a lot.
