Are fajitas low in carbs? Your Guide to a Low-Carb Mexican Favorite

4 min read

A traditional restaurant fajita plate, served with multiple large flour tortillas, can contain over 120 grams of carbohydrates. But are fajitas low in carbs if you make some strategic changes? The answer depends entirely on how you prepare and serve this popular Mexican-American dish, with simple modifications making it a low-carb and keto-friendly meal.

Quick Summary

The carb count in fajitas depends heavily on ingredients, particularly tortillas and sides. The meat and vegetables are naturally low in carbs, allowing for simple adjustments to create a keto or low-carb meal.

Key Points

  • Depends on preparation: Traditional fajitas with flour tortillas are high-carb, but the core ingredients (meat and vegetables) are low-carb.

  • Skip the tortillas: The easiest way to reduce carbs is to replace flour tortillas with lettuce cups, low-carb wraps, or simply serve in a bowl.

  • Watch the sauces: Many pre-made seasonings and marinades contain hidden sugars, so a homemade spice mix is best.

  • Choose smart toppings: Opt for fresh toppings like guacamole, salsa, and cheese, but be mindful of portion sizes and avoid sugary salsas.

  • Order wisely: When dining out, request your fajitas without tortillas, rice, or beans, and ask about the seasoning ingredients.

  • Customize at home: Making fajitas at home allows you complete control over ingredients, ensuring a meal that is low-carb and tailored to your diet.

Understanding the Carb Sources in Fajitas

To determine if fajitas are low in carbs, it's crucial to identify where the carbohydrates in a typical serving come from. While the sizzling platter of meat and vegetables might seem harmless, several components of the traditional preparation can significantly increase the carb count.

The Main Culprit: Tortillas

The most substantial source of carbohydrates in a standard fajita meal is the flour tortillas. A single large flour tortilla can contain between 20 to 30 grams of carbohydrates. With most restaurant servings providing multiple tortillas, the carb count can quickly skyrocket, easily accounting for over 100 grams of carbohydrates for the meal. These refined grains offer little nutritional value beyond simple carbohydrates, which can cause a rapid spike in blood sugar.

Sneaky Carbs: Marinades and Seasonings

Many pre-packaged fajita seasonings and marinades contain added sugars and starches to enhance flavor and texture. These can contribute hidden carbohydrates to your meal without you even realizing it. While the amount might seem small per serving, it can add up, especially for those on a strict ketogenic diet.

High-Carb Sides

Restaurant fajita platters are often served with high-carb side dishes like Mexican rice and refried beans. A cup of white rice can have over 40 grams of carbs, and refried beans are also starchy and high in carbohydrates. These sides are meant to complement the main dish but pose a major challenge for anyone watching their carb intake.

How to Make Fajitas Low in Carbs

The good news is that the core components of fajitas—the grilled protein (chicken, steak, or shrimp) and fresh vegetables (bell peppers and onions)—are naturally low in carbohydrates. By making a few strategic substitutions, you can transform fajitas into a delicious, low-carb meal.

Ditch the Tortillas

The simplest and most effective way to reduce the carb count is to eliminate or replace the flour tortillas. Here are some popular low-carb alternatives:

  • Lettuce wraps: Large, crisp lettuce leaves like iceberg or butter lettuce make excellent, crunchy wraps.
  • Low-carb tortillas: Many brands now offer low-carb tortillas made from ingredients like almond or coconut flour.
  • Fajita bowl: Serve the meat and vegetable mixture in a bowl and top it with cheese, guacamole, and sour cream. This is a popular and satisfying option.

Choose Lean Protein

Lean protein sources like chicken breast, skirt steak, and shrimp are naturally carb-free and packed with protein to keep you full and satisfied. For a keto-specific diet, fattier cuts of meat are also great.

Use Low-Carb Vegetables and Homemade Seasoning

While bell peppers and onions are great low-carb additions, you can also include other vegetables like mushrooms, zucchini, or cauliflower to bulk up your meal. To avoid hidden carbs, prepare your own fajita seasoning using spices like cumin, chili powder, paprika, and garlic powder instead of relying on sugary pre-made packets.

Smart Toppings

Toppings can make or break a low-carb fajita. Stick to fresh, flavorful, and low-carb options such as:

  • Guacamole or sliced avocado
  • Sour cream or Mexican crema
  • Shredded cheese
  • Fresh pico de gallo
  • Chopped cilantro

Ordering Low-Carb Fajitas at a Restaurant

Dining out doesn't have to ruin your low-carb diet. Follow these tips to enjoy restaurant fajitas while staying on track:

  1. Skip the tortillas: Ask for your fajitas without tortillas. If they offer, request lettuce cups instead.
  2. Hold the sides: Politely request no rice or beans. You can ask for extra vegetables or a side salad instead.
  3. Inquire about seasoning: Ask if the restaurant's fajita seasoning contains added sugars. If you're unsure, ask for plain grilled meat and veggies and request a fresh lime wedge to season it yourself.
  4. Manage your toppings: Stick to fresh toppings like salsa and guacamole. Be mindful of sour cream and cheese portions, especially on stricter low-carb diets.

Conclusion

So, are fajitas low in carbs? The simple answer is no, not in their traditional, restaurant-style presentation. However, the components that make up the sizzling core of the dish—the meat, peppers, and onions—are naturally low in carbs. With a few simple substitutions, like swapping flour tortillas for lettuce wraps and avoiding high-carb sides, fajitas can easily become a delicious and healthy low-carb or keto-friendly meal. The key is mindful preparation, whether at home or in a restaurant, to ensure your meal fits your dietary goals.
