Tips and Tricks
1. Marinate for Flavor: If time allows, marinate the chicken for at least 30 minutes (or up to overnight) with lime juice, garlic, and spices to enhance the flavor.
2. Use a Cast Iron Skillet: For that perfect sear, a cast iron skillet retains heat well and helps to achieve those desirable charred edges on the chicken and peppers.
3. Pre-cut Vegetables: To save time, slice your bell peppers and onions in advance so when you’re ready to cook, it’s just a matter of tossing everything in the pan.
4. Customize the Spice Level: Adjust the amount of chili powder and cumin according to your spice preference. You can also add jalapeños for an extra kick!
Make Ahead Tips
You can prep the chicken and vegetables ahead of time. Simply slice the chicken and veggies, and store them in airtight containers in the refrigerator for up to 2 days. For the marinade, combine the spices and lime juice in a jar and keep it in the fridge. When you’re ready to cook, just toss everything together, and you’ll have a delicious meal on the table in no time!

Recipe Variations
1. Protein Swaps: Substitute chicken with shrimp, beef, or tofu for a different protein option.
2. Vegetable Variety: Add other vegetables such as zucchini, mushrooms, or asparagus for extra nutrients and flavor.
3. Cooking Methods: Try grilling the chicken and veggies on an outdoor grill for a smoky flavor or use an air fryer for a healthier, less oily option.
4. Fajita Bowls: For a hearty meal, serve the fajitas over a bed of lettuce or cauliflower rice instead of wrapping them in lettuce leaves.
How to Serve
Serve your Low Carb Chicken Fajitas hot from the skillet, garnished with fresh cilantro and lime wedges. For an added touch, you can offer a selection of toppings such as sliced avocado, sour cream, or shredded cheese. Present the dish in a colorful platter to highlight the beautiful array of colors from the peppers and chicken. For a fun dining experience, let guests assemble their own fajitas!

Pairing Suggestions
For a refreshing drink pairing, consider serving these fajitas with a zesty margarita or a light beer. If you prefer non-alcoholic options, a fresh limeade or iced tea with mint complements the flavors beautifully. As for side dishes, a simple green salad or guacamole would be excellent accompaniments, while a light dessert like a berry salad can round off the meal perfectly.
How to Store
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. If you want to freeze them, place the cooled fajitas in a freezer-safe container, where they can last for up to 2 months. When ready to eat, thaw in the refrigerator overnight and reheat on the stovetop over medium heat until warmed through.
Equipment Needed
- Cast iron skillet or stainless steel frying pan: For perfect cooking and caramelization.
- Sharp knife: For slicing the chicken and vegetables.
- Cutting board: To prepare your ingredients safely.
- Meat thermometer: To ensure your chicken is cooked to the right temperature.

Dietary Adaptations
To make this recipe vegan, replace the chicken with grilled tofu or tempeh and ensure that the marinade is dairy-free. For a dairy-free version, skip the sour cream and opt for avocado or guacamole instead. If you have nut allergies, this recipe is nut-free as is. Always check labels on pre-packaged spices to avoid hidden allergens.
Seasonal Adaptations
In the summer, use fresh, in-season bell peppers and tomatoes for a sweeter flavor. In the fall, consider adding seasonal spices like cinnamon or nutmeg to the marinade for a warm twist. During the winter months, use frozen bell peppers if fresh ones aren’t available, ensuring you have a colorful dish all year round.
