What is a Fajita?
Definition of fajita (meat, vegetables, tortilla)
A fajita is a dish originating from Tex-Mex/US-Mexican cuisine, typically consisting of strips of grilled or sautéed meat (often beef skirt steak originally) combined with sautéed onions and bell peppers, and then served in or with a tortilla (corn or flour) that the diner wraps or folds.
The common format: meat + vegetables + warm tortilla = fajita. The meat provides protein and fat, the vegetables add fibre, vitamins and colour, and the tortilla provides the carbohydrate wrap.
Because of its three-component nature (meat/veg/tortilla) the calorie content of a fajita depends on each of these elements plus cooking method and condiments.
Common types: chicken fajita, beef fajita, shrimp/vegetable fajita
-
Chicken fajita: Made with grilled chicken breast or thigh strips, peppers, and onions. It’s usually leaner and lower in calories compared to beef.
-
Beef fajita: Uses skirt, flank, or sirloin steak. Higher in fat, but richer in flavor and iron.
-
Shrimp or vegetable fajita: Seafood or plant-based versions that are lighter and lower in calories while still offering good protein or fiber.
Typical components that contribute to calories
-
Protein source: Type and amount of meat or seafood used.
-
Cooking fat: Oil or butter used for sautéing adds significant calories.
-
Tortilla: Flour tortillas generally contain more calories than corn tortillas.
-
Toppings and sauces: Cheese, sour cream, guacamole, and creamy sauces can quickly add 200–400 extra calories.
-
Sides: Rice, beans, and chips served with restaurant fajitas often double the total calorie intake.
How Many Calories in a Typical Fajita?
Home-cooked fajita calories
- Chicken fajita: A typical homemade chicken fajita with vegetables and one medium tortilla contains around 350 to 400 calories.
- Beef fajita: A similar serving made with beef averages 400 to 450 calories, depending on the cut and amount of oil used.
- Vegetable-only fajita: A fajita made only with peppers, onions, mushrooms, and a small tortilla typically ranges between 200 to 300 calories.
Restaurant or chain fajita calories
Restaurant fajitas are much higher in calories due to larger portions, oil-heavy preparation, and extra toppings. A single restaurant fajita platter can easily reach 800 to 1,200 calories, especially if served with rice, beans, and multiple tortillas.
Example: A chicken and steak combo fajita plate with all toppings and sides often exceeds 1,000 calories.
Packaged or frozen fajita meals
Pre-made fajita kits and frozen meals generally range from 300 to 400 calories per serving. These usually include chicken or beef, vegetables, and small tortillas. Always check nutrition labels, as sodium and fat can be high in prepackaged versions.
Tortilla type and size impact on calories
Flour vs. corn tortillas:
-
A medium flour tortilla (about 30–35 g) has roughly 100–120 calories.
-
A small corn tortilla of the same weight has around 70–90 calories.
Large vs. small size tortillas: Using large tortillas or doubling up increases the total calorie count quickly. For example, three small flour tortillas can add 250–300 calories on their own.
Additional toppings and sides that add calories
- Cheese: Adds around 100 calories per ¼ cup.
- Sour cream: Adds 60–70 calories per 2 tablespoons.
- Guacamole: Adds 80–100 calories per serving.
- Rice and beans: Add 200–400 calories, depending on portion size.
- Sauces: Creamy or queso sauces add more fat and sodium, while salsa is low in calories but high in sodium.
How toppings can dramatically increase total calorie load: A simple 350-calorie fajita can exceed 900 calories when loaded with cheese, sour cream, guacamole, and sides.

How different ingredient choices affect nutrition profile
-
Choosing lean protein like chicken or shrimp reduces total calories and fat.
-
Using less oil during cooking cuts down unnecessary fat calories.
-
Opting for whole-wheat or corn tortillas increases fiber and reduces calories.
-
Adding more vegetables enhances volume and nutrients without raising calories.
-
Limiting high-fat toppings like cheese and sour cream keeps the dish lighter.
Factors That Most Influence Fajita Calories
-
Portion size: Doubling meat or using two tortillas doubles the calories.
-
Cooking method: Grilling or using a non-stick pan with minimal oil lowers fat compared to pan-frying.
-
Choice of meat: Chicken breast and shrimp are leaner than beef or pork.
-
Tortilla count: Each extra tortilla adds about 100 calories.
-
Toppings: Guacamole, sour cream, and cheese add significant fat calories.
-
Sides: Rice, beans, and chips can add 300–500 calories.
-
Restaurant vs. homemade: Homemade fajitas typically have 30–50% fewer calories due to portion control and reduced oil.
How To Estimate or Calculate Your Fajita Calories
Step-by-step: identify each component
-
Weigh your meat portion (in grams or ounces) and multiply by its calorie value.
-
Estimate vegetables (usually 20–40 calories per 100 g).
-
Add tortilla calories based on type and number used.
-
Include oil (1 tablespoon = ~120 calories).
-
Add toppings (cheese, sauces, etc.).
-
Add sides if served (rice, beans).
Use of food database values
Use nutritional data from USDA, MyFitnessPal, or similar resources to find accurate calorie values for each component. Add them up to estimate your total fajita calories.
Tips for adjusting portion or ingredient to reduce calories
-
Use one tortilla instead of two.
-
Choose corn or whole-wheat tortillas over white flour.
-
Grill instead of fry.
-
Add more vegetables to create volume with fewer calories.
-
Skip or reduce high-calorie toppings like cheese and sour cream.
-
Make a fajita bowl without tortillas to cut 100–150 calories.
-
Use non-stick spray or minimal oil for cooking.
