Fajitas come in parts: a skillet of meat and peppers, a stack of tortillas and a row of small bowls. You build each one yourself, which makes the total easy to lose track of. The parts are also what make fajitas easy to count, once you know what each one adds.
Short answer: one wrapped fajita (3.4 oz) has about 158 to 219 calories, according to USDA: 158 for vegetable, 180 for shrimp, 196 for chicken and 219 for beef or pork. The bigger swing comes from tortillas, toppings and sides. A restaurant-style steak platter with three flour tortillas, guacamole, sour cream, cheese, rice and beans comes to about 1,546 calories.

Fajita calories by protein
USDA weighs one wrapped fajita at 3.4 oz (95 g), tortilla included. Here is one fajita of each kind, and three of them:
One fajita (3.4 oz) | Calories | Protein | Fat | Saturated fat | Sodium | Three fajitas |
|---|---|---|---|---|---|---|
Vegetable | 158 | 3.1 g | 7.4 g | 1.6 g | 326 mg | 473 |
Shrimp | 180 | 7.9 g | 8.5 g | 1.8 g | 433 mg | 539 |
Chicken | 196 | 10.8 g | 9.3 g | 2.0 g | 428 mg | 587 |
Beef or pork | 219 | 11.5 g | 11.6 g | 3.1 g | 436 mg | 658 |
Source: USDA FoodData Central (FNDDS).
The protein moves the count by about 60 calories a fajita, from vegetable to steak. Chicken and beef give the most protein, about 11 g each, but beef carries half again as much saturated fat. Three chicken fajitas come to about 587 calories and 32 g of protein.
Sodium is similar across the meats, about 430 mg a fajita, so three of them reach about 1,300 mg, more than half of the 2,300 mg Daily Value before any salsa or sides.

The oil in the skillet
The fat in the pan is the part of a fajita you never see on the plate. A tablespoon of cooking oil (0.5 oz) adds about 126 calories, and it ends up spread across everything the skillet holds.
USDA's values for cooked peppers and onions show the gap, per cup:
Cooked with added fat: 86 calories, 3.9 g fat
Cooked without added fat: 52 calories, 0.2 g fat
Source: USDA FoodData Central (FNDDS): vegetable oil, peppers and onions cooked with and without fat.
At home, measuring the oil is the simplest fix. Two tablespoons in a skillet that serves four people add about 63 calories to each share; one tablespoon halves that. Brushing the pan instead of pouring cuts it further.
Building each fajita: tortilla, filling and toppings
When you build your own, each layer has its own number.
The tortilla
A medium flour tortilla (1.6 oz) has about 138 calories and 315 mg of sodium; a small one (1.2 oz) has about 101. A medium corn tortilla (1 oz) has about 61 calories and 13 mg of sodium. Our guide to taco calories compares the two in more detail.
The filling
Per 3 oz cooked, shrimp has about 94 calories, chicken breast about 137 and flank steak about 207, with about 15, 26 and 25 g of protein. Half a cup of peppers and onions cooked with fat adds about 43 more.
The toppings
Per spoonful, the toppings run from almost nothing to more than the tortilla:
Pico de gallo, 2 tbsp: 5 calories
Red salsa, 2 tbsp: 11
Guacamole, 2 tbsp: 47
Sour cream, 2 tbsp: 59
Mexican blend cheese, 1/4 cup: 102
Shredded cheddar, 1/4 cup: 116
Source: USDA FoodData Central (FNDDS).
Put together, a medium flour tortilla with 3 oz of chicken, half a cup of peppers and onions, 2 tbsp of guacamole and 2 tbsp of pico comes to about 370 calories, nearly twice USDA's 3.4 oz chicken fajita, because the portion is bigger. For more on the dip itself, see our guacamole nutrition breakdown.
A full fajita platter
Here is a restaurant-style steak platter built from USDA values with common portions, not one restaurant's menu:
Part of the platter | Amount | Calories | Sodium |
|---|---|---|---|
Flank steak | 6 oz | 413 | 629 mg |
Peppers and onions, cooked with fat | 1 cup | 86 | 178 mg |
Flour tortillas, medium | 3 | 413 | 945 mg |
Guacamole | 1/4 cup | 93 | 206 mg |
Sour cream | 2 tbsp | 59 | 15 mg |
Mexican blend cheese | 1/4 cup | 102 | 201 mg |
Pico de gallo | 1/4 cup | 10 | 266 mg |
Spanish rice | 1/2 cup | 140 | 377 mg |
Refried beans, restaurant-style | 1/2 cup | 230 | 523 mg |
Total | 1,546 | 3,340 mg |
Source: USDA FoodData Central (FNDDS); totals worked out from the values for each item.
The tortillas, rice and beans together make up about half the platter, 783 of 1,546 calories. Sodium reaches about 3,340 mg, almost one and a half times the Daily Value, and the plate holds about 83 g of protein. Swap the steak for 6 oz of chicken breast and the platter drops to about 1,406 calories with about the same protein.
A platter like this is easier to log in parts than as one guess. Snap it with a photo calorie tracker like Dietfit and Deep Scan lists the steak, the tortillas and each topping on its own line, so you can change the count to what you actually ate.
Lighter fajitas
Fajitas are easy to trim, because every part comes separately. Four changes and a 4 oz portion of chicken take the chicken platter from about 1,406 calories to about 595:
Cook the peppers and onions without added fat. One cup drops from 86 to 52 calories.
Switch to corn tortillas. Three medium corn tortillas have about 183 calories against 413 for flour, and about 900 mg less sodium.
Keep the toppings light. A quarter cup of pico and 2 tbsp of guacamole (56 calories) in place of guacamole, sour cream and cheese (254).
Pick one side, and make it black beans. Half a cup has about 121 calories and 8 g of protein, and the rice stays in the kitchen.
Source: USDA FoodData Central (FNDDS); totals worked out from the values for each item, with 4 oz of chicken breast.

The lighter platter still holds about 50 g of protein, with about 1,290 mg of sodium instead of 3,320. For fajitas next to tacos, burritos and other dishes, see whether Mexican food is healthy, and for another dish where the count matters more than the filling, see tamales calories.
