December 2, 2025 •

3 min read

According to a study published in the journal Nutrients, Mexican cuisine can be rich in vitamins and fiber, but restaurant versions often contain excess calories, sodium, and unhealthy fats. This means that whether fajitas are a healthy option at a Mexican restaurant depends entirely on how they are prepared and what accompaniments are chosen.

Quick Summary

Fajitas can be a nutritious, high-protein meal with grilled meat and vegetables, but restaurant variations often contain high levels of sodium, calories, and saturated fat. Learn how to customize your order to make it a healthier choice by selecting lean proteins, fresh vegetables, and mindful toppings.

Key Points

Start Smart: Decline the complimentary chips and opt for fresh salsa and guacamole in moderation to save hundreds of calories.
Choose Your Protein: Select lean proteins like grilled chicken, shrimp, or a lean cut of steak to maximize protein intake and minimize saturated fat.
Boost Your Veggies: Request extra bell peppers, onions, and other vegetables to increase fiber, vitamins, and minerals in your meal.
Rethink the Tortilla: Skip the large flour tortillas in favor of smaller corn tortillas or, for a low-carb option, turn your meal into a fajita bowl or lettuce wrap.
Top It Right: Substitute fatty toppings like sour cream and cheese with fresh salsa, pico de gallo, and a small serving of guacamole.
Mind Your Sides: Ask for black beans instead of refried beans and choose grilled vegetables over calorie-dense rice.

The Nutritional Breakdown of Restaurant Fajitas

A traditional fajita plate often arrives sizzling with grilled onions and peppers, alongside a choice of protein. This core combination of lean protein and fresh vegetables is nutritionally sound, providing essential vitamins, minerals, and fiber. However, the healthfulness can be significantly compromised by what comes on the side.

Proteins: Lean chicken breast, shrimp, and certain cuts of steak (like flank or sirloin) offer high-quality protein necessary for muscle repair and satiety. Fattier cuts of beef or pork, such as carnitas or ribeye steak, will increase the saturated fat content.
Vegetables: The sautéed bell peppers and onions are packed with beneficial nutrients like Vitamin C and antioxidants. They add bulk and fiber to the meal, helping you feel full.
Tortillas: The choice of tortilla matters. Large, refined flour tortillas, often served in restaurants, are higher in calories, fat, and sodium than their smaller corn counterparts.
Toppings: This is where calories and fat can quickly accumulate. Standard toppings like sour cream, shredded cheese, and sometimes refried beans add significant saturated fat and sodium.

Making Smarter Choices for a Healthier Fajita

The customizable nature of fajitas makes them a top contender for a healthy Mexican meal when dining out. By being selective, you can enjoy all the flavor with fewer of the drawbacks. The key is controlling your portion sizes and choosing healthier alternatives for each component.

Best practices for ordering healthy fajitas:

Choose lean protein: Opt for grilled chicken breast, shrimp, or a lean cut of steak.
Load up on veggies: Ask for extra peppers and onions, or see if other vegetables like zucchini or mushrooms are available. This boosts fiber and nutrients without adding many calories.
Be selective with tortillas: Order corn tortillas instead of flour, or skip them altogether to make a fajita bowl. For a low-carb option, use lettuce wraps.
Request sauces on the side: This allows you to control how much you consume. Substitute creamy toppings with fresh, healthy alternatives.
Mind your sides: Decline the complimentary chips and queso, and swap refried beans for black beans or pinto beans, which are typically prepared without lard.

Conclusion

In essence, fajitas can absolutely be a healthy option at a Mexican restaurant, provided you are a conscious and careful diner. The core components of lean protein and sautéed vegetables are highly nutritious, and the "build-it-yourself" nature of the dish allows for significant customization.

Frequently Asked Questions

Yes, customized fajitas are generally a healthier option than burritos. Burritos typically contain a large flour tortilla filled with rice, beans, and cheese, leading to a much higher calorie count. Fajitas, with their separate components, allow for greater portion control and healthier ingredient choices.

To reduce sodium, ask for less oil when cooking the meat and vegetables and avoid or limit salty toppings like cheese. Use fresh salsa and lime juice for flavor instead, and choose black beans over saltier refried versions.

Corn tortillas are a healthier choice. They are lower in calories, fat, and sodium compared to large flour tortillas. However, the healthiest option is often to use a fork and eat the fillings as a bowl.

Yes, fajitas can be easily adapted for a low-carb diet. Simply skip the tortillas and any rice, and enjoy the grilled meat and vegetables as a bowl. You can also use large lettuce leaves as a wrap.

Skinless chicken breast and shrimp are the leanest and lowest-fat protein options for fajitas. If you prefer beef, opt for a lean cut like flank or sirloin and limit your portion size.

Guacamole is a healthy topping in moderation. It is made from avocados, which are rich in heart-healthy monounsaturated fats. However, it is also calorie-dense, so it's best to enjoy a small portion.

To keep your fajitas healthy, avoid high-fat and high-sodium additions like sour cream, shredded cheese, and lard-filled refried beans. Also, be mindful of the large portion sizes common in restaurants.
