Mr. Jed Kirlin DDS 06 Jun 2025

Tacos! Just the word itself can make your mouth water. Whether you prefer them soft or crunchy, filled with savory meats or vibrant veggies, tacos are a beloved culinary staple around the world. But as delicious as they are, a common question often pops up for those mindful of their diet: "How many calories are in a taco?"

The simple answer is: it varies! A lot. The calorie count of a taco can swing wildly depending on its size, the ingredients used, and even the cooking method. In this comprehensive guide, we'll dive deep into the world of taco nutrition, breaking down the calorie content of various types of tacos and offering insights to help you make informed choices without sacrificing flavor.

The Great Taco Calorie Mystery: A General Overview

Let's start with a baseline. According to common nutritional data, a popular choice for a standard taco – one with beef, cheese, lettuce, tomato, and salsa – hovers around 170 calories. This is a good starting point, representing a single taco or tostada with these specific components. However, it's crucial to remember that this is just one specific type and serving size, and calorie and nutritional information for a variety of types and serving sizes of tacos is shown below.

Indeed, the number of calories in a taco can vary significantly depending on the ingredients used and the portion size. This is why you'll see a wide range of calorie numbers when you look up taco nutrition. To truly understand, we need to look at the individual components that make up this delicious dish.

Breaking Down the Taco: Component by Component

Every element you add to your taco contributes to its overall calorie count. Understanding the calorie content of each part can help you build a taco that fits your dietary goals. Here’s a breakdown of the approximate calorie content of some common taco components and popular combinations:

Taco Shells

Whether you prefer a soft tortilla or a crispy hard shell, the base of your taco adds calories. While specific calorie counts for shells alone weren't detailed for every type in the provided data, it's a fundamental component. Generally, hard taco shells tend to be slightly higher in calories due to being fried, while soft corn or flour tortillas offer a versatile base.

Protein Fillings

The type and amount of protein you choose for your taco will be a major determinant of its calorie content. Protein options commonly include chicken, beef, fish, or tofu. Here’s a look at some common options and their approximate calorie contributions per taco:

Ground Beef Taco: A standard beef taco with ground beef can be around 230 calories (based on a 3.4 oz serving). For a larger serving or a fast-food version, a hard shell taco with beef, cheese, and lettuce contains approximately 386 calories. This type often has a macronutrient breakdown of 35% carbs, 50% fat, and 15% protein, and is a good source of protein (27% of your daily value), fiber (24% of your daily value), and potassium (8% of your daily value).
Shredded Chicken Taco: A shredded chicken taco (3.4 oz) is often a slightly lighter option, coming in at approximately 210 calories.
Carne Asada Taco: A typical carne asada taco can be around 190 calories. However, for smaller street taco versions (2.0 oz), a carne asada street taco might be as low as 90 calories.
Steak Fajita Taco: A steak fajita taco (2.1 oz) can have about 90 calories.
Chicken Fajita Taco: Similar to steak, a chicken fajita taco (2.0 oz) is often around 80 calories.
Brisket Taco: A brisket taco with BBQ sauce (3.3 oz) can be around 250 calories, while a smaller brisket street taco (2.3 oz) might be around 140 calories.

Toppings and Add-ons

Do toppings affect the overall calorie count of a taco? Absolutely! While fresh veggies like lettuce and tomato add minimal calories, creamy or cheesy toppings can significantly increase the total:

Cheese: A generous sprinkle of cheese adds calories and fat.
Sour Cream: A dollop of sour cream can add a surprising amount of calories.
Guacamole: While healthy fats are good, guacamole is calorie-dense. The calorie count in a taco with guacamole will be higher than one without.
Salsa: Most salsas are low in calories, making them a great flavor enhancer.
Beans: Beans can add fiber and protein, but also calories. A bean & cheese taco, for example, can be around 300 calories.

Understanding Portion Sizes and Their Impact

The size of your taco plays a huge role in its calorie content. What one person considers a "medium" taco might be different from another's. Let's look at some approximate calorie counts based on size and type:

Standard Tacos by Weight

For a general idea of calorie content based on size:

A taco weighing around 102 grams typically contains about 210 calories. This serving size has 9.9g total fat (13% daily value) and 4.2g saturated fat (21% daily value).
A small size serving (90g) of taco: 202.4 kcal.
A medium size taco (112g): 253 kcal.
A big size taco (146g): 328.9 kcal.
A single large taco can contain as many as 568 calories. This large taco's macronutrient breakdown is often around 49% fat, 29% carbs, and 22% protein.

Multiple Servings

If you're having more than one, the calories add up quickly. Here's how many calories are in 1, 2, 3, or 5 servings of tacos:

Two medium size servings of tacos: Approximately 506 kcal.
Three medium size servings of tacos: Approximately 759 kcal.

Street Tacos: A Lighter Option?

Street tacos are generally smaller and often simpler, which can make them a lower-calorie choice. Here's how many calories are in 1, 2, 3, or 5 servings of street tacos:

A medium size street taco (80g): Approximately 150 kcal.
An ounce (oz) of street tacos: 53 kcal.
A half of medium size serving of street taco: 75 kcal.
A small size serving of street taco (64g): Approximately 120 kcal.
A big size street taco (104g): Approximately 195 kcal.
Two medium size servings of street tacos: Approximately 300 kcal.

Specific types of street tacos also vary in calorie count:

Beef street tacos: Around 340 calories.
Chicken street tacos: Around 240 calories.

Specialty Tacos and Fast Food Options

When you head to popular fast-food chains, their menu items often have detailed nutritional information available. For example, Taco Bell provides comprehensive calorie, fat, and protein content for its menu items, allowing users to calculate the nutrition facts for any taco or burrito they choose.

Some specific examples from fast-food menus include:

A bean burrito from Taco Bell, for instance, contains 350 calories, with most of those calories (62%) coming from carbohydrates.
A Cantina Chicken Bowl from Taco Bell is higher, at 490 calories, with most calories coming from fat (44%) and carbohydrates (36%). This bowl features freshly grilled chicken marinated with chipotle peppers and a touch of pure honey.

For those interested in building their own, a taco bowl calorie counter allows users to estimate the total calories in their taco bowl based on the weights of its individual ingredients.

Vegetarian and Vegan Tacos

For those opting for plant-based diets, vegetarian and vegan tacos can be excellent lower-calorie alternatives. These tacos generally range from 100 to 200 calories per serving, depending on the ingredients and toppings. They typically rely on ingredients like beans, tofu, or various vegetables, making them a good option for those watching their calorie intake.

Macronutrient Breakdown and Nutritional Benefits

Beyond just calories, it's helpful to look at the macronutrient breakdown (carbohydrates, fats, and proteins) of your taco. For example:

A beef taco can have a macronutrient breakdown of 17% carbs, 55% fat, and 28% protein. This makes it a good source of protein (providing about 27% of your daily value), vitamin B12 (around 51% of your daily value), and zinc (about 30% of your daily value).
A fast-food taco (beef, cheese, lettuce, hard shell) might be 35% carbs, 50% fat, and 15% protein. It's also a good source of protein (27% of your daily value), fiber (24% of your daily value), and potassium (8% of your daily value).

This shows that while some tacos can be high in fat, they also offer significant nutritional benefits, especially in terms of protein and essential micronutrients.

Burning Off Those Taco Calories

If you're curious about the physical activity needed to burn off your taco, here are some examples:

To burn the 350 calories in a bean burrito, you would typically have to run for about 31 minutes or walk for 50 minutes.
To burn the 490 calories in a Cantina Chicken Bowl, you would need to run for approximately 43 minutes or walk for 70 minutes.

These are just estimates, but they give you an idea of the energy expenditure required.
