Calories and protein in a plate of spaghetti bolognese, with and without olive oil
Also called pasta with ragù, spag bol.
The short answer
1 plate, about 350 g, normal olive oil
570 kcal
26 g protein
Fat 23 g · carbs 65 g · fibre 5 g · With meat or fish
Portion: about 75 g of dry pasta, cooked, with ragù. Calculated from USDA FoodData Central
The fat in the mince matters as much as the oil. Draining the pan after browning lowers it.
With and without olive oil
The same 1 plate, changing only the olive oil the soffritto starts in. Normal is about 4.5 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.

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.

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.
