Ingredients
Method
- Mix the fajita seasoning: In a small bowl, combine 1.5 teaspoons chili powder, 1 teaspoon ground cumin, 1 teaspoon smoked paprika, 1/2 teaspoon oregano, 1/2 teaspoon garlic powder, 1/2 teaspoon onion powder, 1/2 teaspoon salt, and 1/4 teaspoon black pepper.
- Prep the chicken: Pat chicken dry and slice into thin strips. Toss with half the seasoning mix and 1 tablespoon oil. Let it sit while you prep the veggies.
- Slice the veggies: Cut bell peppers and onion into thin strips. Keep them roughly the same size so they cook evenly.
- Sear the chicken: Heat a large skillet over medium-high heat with 1 tablespoon oil. Add chicken in a single layer. Cook 4–6 minutes, turning once, until browned and cooked through. Transfer to a plate and tent with foil.
- Cook the peppers and onions: Add 1 tablespoon oil to the same skillet. Toss in peppers and onion with a pinch of salt. Cook 5–7 minutes, stirring occasionally, until tender with a bit of char. Stir in minced garlic and the remaining seasoning. Cook 30 seconds more. Return chicken to the pan, squeeze in juice from half a lime, and toss.
- Make the cauliflower rice: In a second skillet, heat 1 tablespoon oil or butter over medium. Add cauliflower rice with a pinch of salt and pepper. Cook 4–5 minutes until tender but not soggy. Zest in a little lime and add chopped cilantro for extra flavor.
- Assemble the bowls: Add a base of cauliflower rice. Top with chicken and fajita veggies. Add avocado, a squeeze of lime, and any toppings you like.
- Taste and adjust: Add more salt, lime, or a sprinkle of chili powder if you want more punch.

Keeping It Fresh
- Storage: Keep chicken and veggies in one container and cauliflower rice in another for up to 4 days in the fridge.
- Reheating: Warm gently on the stovetop over medium heat or in the microwave in short bursts.
Add a splash of water or oil to keep things juicy.

- Freezing: Freeze the cooked chicken and veggies up to 2 months. Thaw overnight and reheat. Make fresh cauliflower rice and toppings when serving.
Health Benefits
- Keto-friendly macros: Low net carbs, higher fat from avocado and optional cheese, and steady protein from chicken.
- Fiber and micronutrients: Bell peppers and cauliflower bring vitamin C, potassium, and fiber to support digestion and immunity.
- Healthy fats: Avocado and olive oil support heart health and satiety, helping you stay full longer.
- No added sugar: Clean spices and lime juice deliver flavor without hidden carbs.
What Not to Do
- Don’t overcrowd the pan: You’ll steam the chicken instead of searing it.
Cook in batches if needed.
- Don’t skip the seasoning rest: A few minutes on the chicken helps the spices stick and boosts flavor.
- Don’t overcook the peppers: You want tender-crisp with a bit of char, not mushy.
- Don’t drench it in sugary sauces: Check labels on salsa or hot sauce. Choose no-sugar-added options to keep it keto.
- Don’t forget acidity: Lime brightens everything. Without it, the bowl can taste flat.
Variations You Can Try
- Swap the protein: Use shrimp, steak, or turkey.
Adjust cook times—shrimp cooks in 2–3 minutes.
- Add low-carb veggies: Zucchini ribbons, mushrooms, or shredded cabbage work well and add volume.
- Cheesy cauliflower rice: Stir in shredded cheddar or cotija to the cauliflower rice for extra richness.
- Spice it up: Add chipotle powder, cayenne, or sliced jalapeños for more heat.
- Bowl base twist: Try shredded lettuce or sautéed spinach instead of cauliflower rice for a lighter bowl.
- Dairy-free: Skip cheese and sour cream; use extra avocado and a drizzle of olive oil.
FAQ
How many carbs are in a keto chicken fajita bowl?
Carbs will vary based on toppings and serving size, but a typical bowl with chicken, peppers, onions, avocado, and cauliflower rice lands around 8–12 net carbs. Keep an eye on salsa and cheese to stay within your target.
Can I prep this ahead of time?
Yes. Cook the chicken, peppers, and cauliflower rice, then store separately.
Reheat just before serving and add fresh toppings like avocado, cilantro, and lime.
Do I need a cast-iron skillet?
No, but it helps. Cast iron gets hot and holds heat, which gives a great sear. Any large, heavy skillet works fine—just avoid overcrowding.
Can I use a store-bought fajita seasoning?
You can, but check the ingredients.
Choose a blend without added sugar, cornstarch, or fillers. Making your own gives you control over flavor and carbs.
What if I don’t like cauliflower rice?
Use shredded lettuce, sautéed cabbage, or riced broccoli. You can also skip the base and serve the chicken and veggies with avocado on top.
