Calories in pesto
Calories, protein, carbohydrate and fat per 100 g and per serving, from the USDA reference database — plus what actually changes the number on your plate.
Short answer
100 g of pesto contains 418 kcal, with 9.8 g of protein, 10.1 g of carbohydrate and 37.6 g of fat.
A typical serving — 1 tablespoon, about 16 g — is roughly 67 kcal.
That is a very calorie-dense food: small amounts carry a lot of energy, and it is easy to under-count.

Where the calories come from
Calories come from three macronutrients: protein and carbohydrate at 4 kcal per gram, fat at 9 kcal per gram. For pesto the split is:
- Protein: 9.8 g × 4 = 39 kcal — 9% of calories
- Carbohydrates: 10.1 g × 4 = 40 kcal — 10% of calories
- Fat: 37.6 g × 9 = 338 kcal — 81% of calories
- Most of the energy in pesto comes from fat (81% of calories).
- 6.3 g of its carbohydrate per 100 g is sugar.
- It is high in sodium: 603 mg per 100 g.
- For 200 kcal you can eat about 50 g.
What actually changes the number
Pesto is 418 kcal per 100 g — oil, pine nuts and cheese — and a tablespoon is 65 kcal. A generous restaurant portion on pasta is 60–80 g, adding 250–330 kcal to the plate.
How accurate are these numbers?
The values on this page are reference averages from the USDA FoodData Central database (SR Legacy release), measured on samples of pesto as sold and prepared in the United States. Your portion will differ: produce varies by variety and ripeness, meat by cut and trim, and anything cooked by the fat and water it gained or lost.
For most foods the per-100 g figure is reliable to within about 10%. The larger uncertainty is almost always the weight of what is on your plate and the cooking fat you cannot see — the two things worth checking before you worry about the database.
