How Many Calories Is One Serving of Spaghetti With Tomato Sauce?

When it comes to monitoring our calorie intake, understanding the nutritional value of our meals is essential. If you’re a pasta lover, one common question that might come to mind is how many calories are in a serving of spaghetti with tomato sauce. In this article, we will delve into the details and provide you with the answer.

The Components

To determine the number of calories in a serving of spaghetti with tomato sauce, we need to consider two main components: the pasta and the sauce.

The Pasta

Before we can calculate the calorie content, it’s important to note that there are different types of pasta available. For simplicity, let’s assume we are using regular white spaghetti. One serving of cooked spaghetti typically weighs around 2 ounces (57 grams).

The Tomato Sauce

Tomato sauce is generally low in calories compared to other sauces. For our calculation, let’s consider a basic tomato sauce made from tomatoes, onions, garlic, and olive oil.

Calorie Calculation

Now that we have an idea about the components let’s break down the calorie content:

  • Spaghetti: One ounce (28 grams) of cooked spaghetti contains approximately 25-30 calories. Therefore, a serving size of 2 ounces would contribute around 50-60 calories.
  • Sauce: The calorie content may vary depending on the recipe and portion size. On average, one serving (1/2 cup) of basic tomato sauce contains around 70-80 calories.

Total Calories

To find the total calorie content of one serving of spaghetti with tomato sauce, we need to add the calories from the pasta and the sauce:

Total Calories = Calories from Spaghetti + Calories from Sauce

Let’s consider a rough estimate:

  • Calories from Spaghetti (2 ounces): 50-60 calories
  • Calories from Sauce (1/2 cup): 70-80 calories

Therefore, one serving of spaghetti with tomato sauce contains approximately 120-140 calories.


When it comes to monitoring your calorie intake, knowing the nutritional content of your meals is crucial. In the case of spaghetti with tomato sauce, one serving typically contains around 120-140 calories. However, it’s important to keep in mind that portion sizes and recipe variations can affect these numbers.

If you are on a specific diet or have dietary restrictions, it’s always best to consult a nutritionist or refer to nutritional labels for accurate information. Remember, moderation is key when enjoying your favorite pasta dishes while maintaining a balanced diet.
