Ingredients
Method
- Prep the chicken: Pat chicken dry and slice into thin strips. Toss with 1–2 tablespoons oil, the fajita seasoning, and the zest and juice of 1 lime. Let it sit while you prep the veggies, at least 10–15 minutes.
- Slice the veggies: Cut peppers and onion into even strips for quick, even cooking. Keep them on the thicker side so they don’t turn mushy.
- Cook the cauliflower rice: Heat 1 tablespoon oil in a large skillet over medium-high heat. Add cauliflower rice, a pinch of salt, and pepper. Sauté 4–6 minutes until tender with a little bite. Stir in a squeeze of lime and some chopped cilantro. Transfer to a bowl and keep warm.
- Sear the chicken: Add a bit more oil to the hot skillet. Cook the chicken in a single layer without crowding. Sear 3–4 minutes per side until cooked through and lightly charred on the edges. Work in batches if needed. Remove to a plate and cover loosely.
- Sauté the peppers and onions: Add a final drizzle of oil if the pan looks dry. Toss in peppers and onions with a pinch of salt. Cook 5–7 minutes, stirring occasionally, until tender-crisp and slightly charred. For extra flavor, add a small pinch of fajita seasoning near the end and a squeeze of lime.
- Combine or keep separate: You can return the chicken to the pan with the veggies for a quick toss, or keep components separate to control portions when assembling bowls.
- Assemble the bowls: Divide cauliflower rice among 4 meal prep containers. Top with chicken, then peppers and onions. Add shredded cheese while warm so it softens slightly.
- Add toppings: Let bowls cool, then add small containers of sour cream, sliced avocado (or pack separately), extra lime wedges, and chopped cilantro. If packing hot and cold items together, keep toppings in separate lidded cups.
- Final taste check: Before sealing, taste one bite and adjust with extra salt, lime, or a sprinkle of cayenne for heat. Small tweaks make a big difference.

Instead, you’ll build bowls around seasoned chicken and sautéed veggies, with low-carb add-ins like cauliflower rice and avocado.

You can scale it up, swap proteins, or tweak the spice level to fit your taste. It’s a reliable, flexible option for busy weeks and keto goals.

Benefits of This Recipe
- Low-carb and keto-friendly: You get satisfying protein and fat without grains or added sugar.

- Meal prep win: Scales easily and stays tasty for days, saving time and money.
- Balanced macros: Chicken for protein, avocado and cheese for healthy fats, and non-starchy veggies for fiber.
- Customizable: Adjust spice, swap proteins, and tailor toppings to your diet.
Pitfalls to Watch Out For
- Overcrowding the pan: This steams the chicken and prevents browning. Cook in batches for a proper sear.
- Watery cauliflower rice: Too much moisture leads to soggy bowls. Cook on medium-high heat and let steam escape.
- Overcooking peppers: Aim for tender-crisp.
Mushy peppers lose their fajita charm.
- Hidden sugars in seasoning: Many mixes add sugar or starch. Use a sugar-free blend or make your own.
- Adding avocado too early: It browns. Add right before eating or pack with lime and keep airtight.
Variations You Can Try
- Protein swaps: Try shrimp, steak, or turkey.
Adjust cook times: shrimp cooks in 2–3 minutes, steak 2–4 minutes per side depending on doneness.
- Spice twist: Add chipotle powder for smoky heat, or use ancho chili for a mild, rich flavor.
- Veggie add-ins: Zucchini ribbons, mushrooms, or poblano peppers add depth while keeping carbs low.
- Dairy-free: Skip cheese and sour cream. Use guacamole, extra olive oil, or a cashew-lime crema (if it fits your plan).
- Bowl base ideas: Swap cauliflower rice for shredded lettuce, cabbage slaw, or sautéed broccoli rice.
- Salsa upgrade: Spoon on a sugar-free pico de gallo or roasted salsa verde for brightness.
FAQ
How many carbs are in each bowl?
It depends on toppings and portion sizes, but a typical bowl with cauliflower rice, chicken, peppers, onions, cheese, and sour cream lands around 8–12 net carbs. Keep avocado portions modest and check labels on spice mixes and cheeses to avoid hidden carbs.
Can I make this without a cast-iron skillet?
Yes.
Any large, heavy skillet works. Just make sure it’s hot before adding chicken to get a good sear and avoid crowding the pan.
How do I keep the chicken juicy?
Slice evenly, don’t overcook, and let it rest a few minutes after searing. Thighs are more forgiving than breasts if you want extra insurance against dryness.
Is this recipe spicy?
It’s mildly spicy as written.
For more heat, add cayenne, crushed red pepper, or use pepper jack cheese. For less heat, skip the cayenne and use a mild chili powder.
Can I make it ahead for the whole week?
Absolutely. Prep 6–8 portions by doubling the recipe.
Store in the fridge up to 4 days, and freeze extra portions without fresh toppings for longer storage.
What’s the best way to reheat without drying out the chicken?
Reheat gently at 50–70% power in the microwave, stirring once, or warm in a covered skillet over low heat with a splash of water or broth. Add toppings afterward.
Are store-bought fajita seasonings okay for keto?
They can be, but check the label. Choose blends without sugar, cornstarch, or maltodextrin.
Making your own is the safest and often tastiest option.
Can I use rotisserie chicken?
Yes. Toss shredded rotisserie chicken with oil, lime, and seasoning, then warm briefly in a skillet. It’s a fast shortcut for busy nights.
What if I don’t like cauliflower rice?
Use shredded lettuce or cabbage slaw for a fajita salad feel, or sautéed broccoli rice.
All keep carbs low while adding crunch or texture.
How do I prevent the bowls from getting watery?
Cook off moisture from the cauliflower rice, let all components cool before sealing, and pack wet toppings separately. A small paper towel on top before sealing can absorb excess condensation.
