Low Carb Chicken Fajita Meal Prep Bowls - Easy, Flavor-Packed, and Weeknight Friendly
Ingredients
Method
- Mix the seasoning: In a small bowl, combine chili powder, cumin, smoked paprika, garlic powder, onion powder, oregano, cayenne, salt, and black pepper. Set aside.
- Prep the chicken: Pat the chicken dry, then toss with half the seasoning and 1 tablespoon of oil. Squeeze the juice of half a lime over the chicken and set aside while you prep the veggies.
- Cook the peppers and onions: Heat a large skillet over medium-high heat with 1/2 tablespoon oil. Add peppers and onions, sprinkle with a big pinch of salt and the remaining seasoning. Cook 6–8 minutes, stirring occasionally, until tender-crisp with some char. Transfer to a plate.
- Cook the chicken: In the same skillet, add the remaining 1/2 tablespoon oil. Add the chicken in a single layer. Cook 5–7 minutes, stirring a couple of times, until browned and cooked through. Squeeze the remaining half of the first lime over the chicken and toss.
- Finish together: Return peppers and onions to the skillet. Toss with the chicken for 1–2 minutes to mingle flavors. Taste and adjust salt, pepper, or cayenne. Turn off heat and sprinkle with chopped cilantro.
- Cook the cauliflower rice: In a separate pan, heat 1 tablespoon oil or butter over medium heat. Add cauliflower rice, a pinch of salt, and cook 4–6 minutes until hot and slightly tender but not mushy. Squeeze a little lime over it for flavor.
- Assemble bowls: Divide cauliflower rice among 4 containers. Top with equal portions of chicken fajitas. Add lime wedges. If using avocado, cheese, salsa, or sour cream, pack them separately to add right before eating.

Benefits of This Recipe
- Low carb, high satisfaction: Cauliflower rice keeps carbs low while the protein and fiber help you stay full.
- Great for planning: Built for batch cooking, with components that store and reheat well.
- Budget-friendly: Uses common pantry spices and affordable produce.
- Balanced flavor profile: Smoky, bright, a little spicy—so you won’t miss tortillas.
- Customizable: Easy to tailor heat level, veggies, and toppings to your taste or dietary needs.
What Not to Do
- Don’t overcrowd the skillet: If the pan is packed, the chicken will steam instead of sear.
Cook in batches if needed.
- Don’t skip drying the chicken: Excess moisture prevents browning and dilutes seasoning.
- Don’t overcook the veggies: You want tender-crisp peppers with a little bite, not mush.
- Don’t add avocado too early: It browns quickly. Add it fresh before serving.
- Don’t forget acid and salt: A final squeeze of lime and a small pinch of salt at the end make flavors pop.
Variations You Can Try
- Sheet pan version: Toss chicken, peppers, and onions with oil and seasoning. Spread on a lined sheet pan and roast at 425°F (220°C) for 18–22 minutes, stirring once.
- Different protein: Use chicken thighs for extra juiciness, or try steak, shrimp (cook 3–4 minutes), or turkey.
- Veggie boost: Add zucchini strips or mushrooms.
Roast or sauté briefly to avoid excess moisture.
- Spice switch: Swap smoked paprika for chipotle powder, or add a dash of coriander for a citrusy note.
- Saucy finish: Stir in a tablespoon of tomato paste plus a splash of chicken broth for a glossy, slightly saucy fajita mix.
- Different base: Use shredded lettuce, cabbage slaw, or riced broccoli instead of cauliflower rice.
- Dairy-free or keto tweaks: Skip cheese and sour cream for dairy-free; for stricter keto, keep onions moderate and focus on peppers and chicken.
FAQ
How many servings does this make?
This recipe makes about 4 meal prep bowls. If you prefer larger portions or are tracking macros closely, divide into 3 containers and adjust sides as needed.
Is it spicy?
It has a gentle kick from cayenne and chili powder. For milder heat, reduce or omit the cayenne.
For extra heat, add chipotle powder or sliced jalapeños.
Can I use pre-cut fajita veggies or a store-bought seasoning packet?
Yes, both work in a pinch. If using a packet, check the label for added sugar or starch and adjust salt since many packets are already salty.
What’s the best way to keep the chicken juicy?
Slice evenly, pat dry, and cook over medium-high heat without crowding. A quick sear locks in moisture.
Finishing with lime juice adds brightness without drying it out.
Can I make this without a skillet?
Absolutely. The sheet pan method at 425°F works great and is hands-off. Just avoid piling ingredients too closely so they roast instead of steam.
How do I keep cauliflower rice from getting soggy?
Cook it quickly over medium heat with a little fat and minimal stirring.
Avoid covering the pan, and don’t add extra liquid. Season at the end.
What low-carb toppings do you recommend?
Fresh cilantro, extra lime wedges, sliced avocado, jalapeños, shredded cheese, and a spoonful of sour cream or Greek yogurt are all solid choices. Salsa adds brightness with few carbs.
Can I grill the chicken and veggies?
Yes.
Use a grill basket for the peppers and onions. Grill chicken over medium-high heat, 3–4 minutes per side, until cooked through.
How long does it keep in the fridge?
Stored properly, the bowls last up to 4 days. Add fresh toppings right before serving for the best texture and flavor.
What if I don’t like cilantro?
Skip it or substitute chopped parsley or green onions.
The lime and spices will still carry the dish.
