Looking for a quick, low-calorie, low-carb, and gluten-free dinner? These low-carb chicken fajitas fit the bill. All you need is chicken, bell peppers, onion, and a simple seasoning blend.
This chicken fajita plate clocks in at about 198 calories per serving with roughly 16 g protein, 12 g carbs, and 10 g fat (most carbs come from the vegetables).
Simple family dinner strategy: cook one batch of the seasoned chicken and sautéed vegetables for everyone. Serve yours on a bed of lettuce or cauliflower rice to keep calories and carbs low. Family members who want a heartier option can load theirs into tortillas — everyone gets what they prefer without extra cooking.
This approach keeps dinner uncomplicated and flexible. For example, my portion was about 200 calories while others who used tortillas ate around 350+ calories. One main dish, multiple serving options.

What ingredients are in these low carb fajitas?
This recipe started with a 12-ounce package of chicken thighs, sliced into strips — that yields about 3 ounces of cooked chicken per serving when divided into four servings. You can adjust the amount of chicken, but remember to recalculate calories and macros if you change the quantity.
We prefer thighs for flavor, but swap in chicken breasts if you want to save a few calories for a stricter deficit.
I sliced a medium onion and three bell peppers (different colors) into strips and used a fajita seasoning. Pre-made fajita seasoning is convenient, but I mixed a quick homemade blend for this batch.
Homemade fajita seasoning:
- 1 tablespoon chili powder
- 1 teaspoon salt
- 1/2 teaspoon paprika
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/4 teaspoon ground cumin
- 1 tablespoon corn starch
- 1 tablespoon golden monk fruit sweetener (optional)
To assemble, scoop the chicken and vegetables onto lettuce leaves and top with a tablespoon of light sour cream. If you prefer, serve the filling in tortillas — there are plenty of low-calorie tortilla options that still allow you to stay on track.
