Ingredients
Method
- Prep the chicken: Pat chicken dry and slice into thin strips. In a bowl, combine 1.5 teaspoons chili powder, 1 teaspoon smoked paprika, 1 teaspoon cumin, 1/2 teaspoon garlic powder, 1/2 teaspoon onion powder, 1/2 teaspoon oregano, 3/4 teaspoon salt, and 1/4 teaspoon black pepper. Add 1 tablespoon oil and the juice of 1/2 lime. Toss chicken with the spice mix; let it sit while you prep veggies.
- Slice the veggies: Core and slice bell peppers into thin strips. Slice onion into thin half-moons. Roughly chop cilantro and set aside. Cut remaining limes into wedges.
- Rice the cauliflower (if not using pre-riced): Cut cauliflower into florets and pulse in a food processor until rice-like. Don’t overdo it or it gets mushy.
- Cook the chicken: Heat a large skillet over medium-high heat with 1 tablespoon oil. Add chicken in a single layer. Sear 3–4 minutes, flip, and cook another 2–3 minutes until cooked through and lightly charred at the edges. Transfer to a plate and tent loosely.
- Sauté peppers and onion: In the same skillet, add another drizzle of oil if needed. Add onions and peppers with a pinch of salt. Cook 5–7 minutes, stirring occasionally, until tender-crisp with some char. Squeeze in a little lime juice and scrape up browned bits for extra flavor.
- Make the cauliflower rice: In a separate skillet, heat 1 tablespoon oil over medium. Add cauliflower rice with a pinch of salt and pepper. Cook 4–6 minutes, stirring, until just tender but not soggy. Finish with a squeeze of lime and a handful of chopped cilantro.
- Assemble the bowls: Add a bed of cauliflower rice to each bowl. Top with chicken, peppers, and onions. Add avocado slices, a dollop of sour cream, a sprinkle of cheese, and cilantro. Serve with lime wedges and jalapeños if you like heat.
- Taste and adjust: Add more salt, lime, or hot sauce to balance flavors. You want bright, savory, and a hint of smoky spice.

Keeping It Fresh
- Storage: Store chicken, peppers, and cauliflower rice separately in airtight containers for up to 4 days.
Keep toppings like avocado and cilantro fresh by adding them the day you eat.
- Reheating: Reheat chicken and veggies together in a skillet over medium heat to revive char and texture. Microwave works too, but use short bursts to avoid drying out.
- Avocado tip: If prepping ahead, slice avocado just before serving. Or store cut avocado with a squeeze of lime and press plastic wrap directly onto the surface to slow browning.
- Freezer-friendly: The cooked chicken and peppers freeze well for up to 2 months.
Cauliflower rice is best made fresh, but frozen works in a pinch.
Why This is Good for You
- Protein-forward: Chicken delivers the protein you need for steady energy and muscle support.
- Healthy fats: Avocado, cheese, and sour cream provide satiating fats that fit a keto lifestyle.
- Low-carb veggies: Peppers, onions, and cauliflower add fiber, color, and micronutrients with fewer carbs than tortillas or rice.
- Custom macros: You control the fat and protein by adjusting toppings and portion sizes, keeping you aligned with your goals.
Pitfalls to Watch Out For
- Hidden sugars: Store-bought fajita seasonings and hot sauces can have added sugar. Make your own blend and read labels.
- Overcooked cauliflower rice: It goes mushy fast. Keep the heat moderate and stop when it’s just tender.
- Dry chicken: Thin slices cook quickly.
Don’t walk away from the pan. Pull them as soon as they’re done.
- Too little seasoning: Salt enhances everything. Taste and adjust at the end with salt and lime to make flavors pop.
Recipe Variations
- Steak or shrimp fajita bowl: Swap in flank steak (thinly sliced) or shrimp.
Cook shrimp 1–2 minutes per side; steak 2–3 minutes per side for medium.
- Spicy chipotle version: Add 1–2 teaspoons minced chipotle in adobo to the chicken marinade for smoky heat.
- Creamy cilantro-lime drizzle: Blend sour cream, lime juice, cilantro, and a pinch of salt for a quick sauce.
- Cheesy skillet bake: Transfer cooked chicken and veggies to a baking dish, top with cheese, and broil until bubbly. Spoon over cauliflower rice.
- Greens instead of rice: Serve over chopped romaine or mixed greens for a fajita salad. Keep the warm toppings; the contrast is great.
- Dairy-free: Skip cheese and sour cream, and add extra avocado and a drizzle of olive oil.
FAQ
How many carbs are in a keto chicken fajita bowl?
Carbs vary with toppings and portions, but a typical bowl with cauliflower rice, chicken, peppers, onions, avocado, cheese, and sour cream lands around 8–12 net carbs per serving.
Use less onion and watch toppings to bring it even lower.
Can I use a store-bought fajita seasoning?
Yes, but check the label for added sugar, corn starch, or fillers. If in doubt, make your own with simple spices so you control the carbs and salt.
Do I need a cast-iron skillet?
No, but cast iron delivers great sear and char. Any large skillet works.
Just preheat well and avoid overcrowding so the chicken browns instead of steams.
Can I make it in the oven?
Absolutely. Toss chicken, peppers, and onions with oil and seasoning. Spread on a sheet pan and roast at 425°F (220°C) for 15–20 minutes, stirring once, until cooked and lightly charred.
What if I don’t like cauliflower rice?
Use shredded cabbage sautéed until just tender, or serve the fajita mix over a bed of crisp romaine for a hearty salad.
Both stay low-carb and taste great.
How can I add more fat to hit my keto macros?
Use chicken thighs, add extra avocado, drizzle olive oil, or top with a creamy cilantro-lime sauce. Cheese and sour cream also help boost fats.
Is this recipe spicy?
It’s mild as written. For more heat, add jalapeños, extra chili powder, or a splash of hot sauce.
For less heat, stick to smoked paprika and cumin and skip the chiles.

A Keto Chicken Fajita Bowl gives you all the sizzle of classic fajitas without the carb-heavy extras. It’s bright, savory, and simple to make, with easy swaps to match your taste and macros.
