Ingredients
Method
- Prep the seasoning: In a small bowl, mix chili powder, smoked paprika, cumin, garlic powder, onion powder, oregano, salt, pepper, and cayenne.
- Season the chicken: Pat chicken dry. Toss with half the seasoning and 1 tablespoon olive oil. Let sit 10–15 minutes while you slice the veggies.
- Cook the chicken: Heat a large skillet over medium-high. Add the chicken in a single layer. Sear 4–5 minutes per side until browned and cooked through. Transfer to a plate and squeeze on the lime juice.
- Sauté the veggies: In the same skillet, add the remaining 1 tablespoon olive oil. Add peppers and onions with the rest of the seasoning. Cook 5–7 minutes, stirring, until tender-crisp with a bit of char.
- Optional base: If using cauliflower rice, sauté it in a little oil with a pinch of salt for 3–5 minutes until just tender.
- Assemble: Divide greens or cauliflower rice into bowls. Top with chicken and fajita veggies.
- Finish and serve: Add avocado, cheese (if using), a dollop of sour cream, cilantro, and a squeeze of lime. Taste and adjust salt or lime as needed.

Keeping It Fresh
- Store smart: Keep chicken and veggies in one container, and greens, avocado, cheese, and sauces in separate containers. This keeps textures crisp.
- Fridge life: Cooked chicken and veggies last 3–4 days.
Slice avocado fresh or use lime juice to slow browning.
- Reheat right: Warm chicken and veggies in a skillet for 2–3 minutes to revive that fajita sizzle. Avoid microwaving the greens.
- Prep ahead: Mix the seasoning in bulk and pre-slice peppers and onions. Dinner comes together in under 20 minutes.
Why This is Good for You
- Low-carb and keto-friendly: Skipping tortillas and grains keeps net carbs low while still feeling hearty.
- Protein-forward: Chicken provides a satisfying protein base that helps control hunger.
- Healthy fats: Olive oil and avocado support satiety and steady energy.
- Micronutrient-rich: Bell peppers deliver vitamin C; onions and greens add fiber and antioxidants.
- No added sugar: The spice blend builds flavor without sugary marinades.
Pitfalls to Watch Out For
- Hidden carbs: Store-bought fajita blends can include starches or sugar.
Make your own to be safe.
- Overcooking chicken: Dry chicken ruins the bowl. Pull it once it’s just cooked through and let it rest.
- Watery veggies: Crowding the pan steams onions and peppers. Cook in batches for good color and flavor.
- Greens wilt fast: Don’t add hot veggies directly to delicate lettuce if you plan to store.
Cool slightly first.
- Too light on salt or acid: A pinch more salt and a squeeze of lime can make the whole bowl pop.
Recipe Variations
- Spicy chipotle: Add minced chipotle in adobo or extra cayenne to the seasoning and finish with jalapeño slices.
- Creamy poblano: Swap bell peppers for roasted poblanos and drizzle with a quick cilantro-lime crema.
- Steak or shrimp: Use flank steak (thinly sliced, quick-seared) or shrimp (2–3 minutes per side). Keep the same seasoning.
- Dairy-free: Skip cheese and sour cream; add extra avocado or a drizzle of tahini-lime sauce.
- Extra veg: Toss in zucchini ribbons or mushrooms. Sauté separately to avoid excess moisture.
- Bowl base swap: Try shredded cabbage, riced broccoli, or a mix of arugula and romaine for different textures.
FAQ
How many carbs are in a Keto Chicken Fajita Bowl?
With lettuce as the base and no cheese, the bowl typically lands around 7–10 net carbs per serving, depending on pepper size and avocado portion.
Using cauliflower rice may add 2–3 net carbs. Always calculate based on your exact ingredients.
Can I use a store-bought fajita seasoning?
Yes, but check the label. Look for blends without sugar, cornstarch, or maltodextrin.
If carbs matter, homemade seasoning is the safest bet and usually tastes fresher.
What’s the best cut of chicken for this?
Chicken thighs are forgiving and stay juicy, especially at high heat. Chicken breasts work well if sliced thin and not overcooked.
How do I get that restaurant-style char?
Use a large skillet or cast-iron pan, preheat it well, and avoid crowding. Cook the chicken and veggies in batches and let them sit undisturbed for a minute before stirring to develop color.
Can I make it ahead for lunches?
Absolutely.
Store the base components separately, then reheat the chicken and veggies and assemble just before eating. Add avocado and toppings fresh for the best texture.
Is sour cream keto-friendly?
Yes, in moderation. Choose full-fat sour cream and watch portions.
You can also use full-fat Greek yogurt if you tolerate dairy.
How can I make it spicier without changing the flavor too much?
Increase cayenne slightly or add minced jalapeño on top. A dash of hot sauce at the end also boosts heat without overwhelming the seasoning.
What if I don’t have fresh lime?
Use a splash of apple cider vinegar in a pinch. Lime is ideal for that bright, classic fajita finish, but a little acid of any kind helps lift the flavors.
