Calories and protein in a plate of risotto parmigiano, with and without butter and olive oil
Also called parmesan risotto, risotto bianco.
The short answer
1 plate, about 340 g, normal butter and olive oil
460 kcal
10 g protein
Fat 17 g · carbs 67 g · fibre 0.5 g · Vegetarian
Portion: a main course plate. Calculated from USDA FoodData Central
The stock is mostly water, but the butter and cheese stirred in at the end add up quickly.
With and without butter and olive oil
The same 1 plate, changing only the butter and oil it is cooked and finished with. Normal is about 14 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.
| Butter and olive oil | Added | Calories | Protein |
|---|---|---|---|
| None | 0 g | 370 kcal | 10 g |
| A little | 7 g | 420 kcal | 10 g |
| Normal | 14 g | 460 kcal | 10 g |
| A lot | 27 g | 550 kcal | 9.5 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 butter and 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.
- Arborio or carnaroli is calculated as USDA short-grain white rice.
- Stock is calculated as water with salt; a meat or bone stock adds a little protein and fat.
- White wine is left out.
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.
