Smoky marinated chicken, charred peppers, and cauliflower rice come together in a bowl that doesn’t need a tortilla to be good.
Sizzling chicken, melty cheese, and zero guilt about the tortilla you’re skipping. That’s the whole pitch.
I started making these fajita bowls when I was trying to cut carbs without cutting flavor. Big mistake energy usually. Not here.
The chicken gets a smoky, citrusy marinade. The peppers and onions char up in the same pan. Everything piles into a bowl with cauliflower rice, avocado, and a squeeze of lime. Fifteen carbs a bowl, maybe less depending on your toppings.
I’ve made this one so many times my husband stopped asking what’s for dinner on Tuesdays. He just knows.
Let’s get into it.
What You’ll Need

- 1 red bell pepper, sliced
- 1 yellow bell pepper, sliced
- 1 green bell pepper, sliced
- 1 medium yellow onion, sliced
- 1 tbsp olive oil
For the bowls
- 4 cups cauliflower rice

- 1/4 cup sour cream
- 1/4 cup fresh cilantro, chopped
- 1 lime, cut into wedges

How to Make Low Carb Chicken Fajita Bowls
- Marinate the chicken. Whisk together the olive oil, lime juice, garlic, chili powder, cumin, smoked paprika, onion powder, salt, and pepper in a large bowl. Add the chicken and toss to coat. Let it sit for at least 20 minutes on the counter, or up to 8 hours in the fridge.
- Cook the chicken. Heat a large skillet over medium-high heat. Add the chicken (shake off excess marinade first) and cook for 6 to 7 minutes per side, until it hits 165°F inside and has a nice char on the outside. Move it to a cutting board and let it rest for 5 minutes before slicing.
- Char the veggies. In the same skillet, add another tablespoon of olive oil and toss in the peppers and onion. Cook for 6 to 8 minutes, stirring occasionally, until they’re softened with a few blackened edges. Those charred bits are where the flavor lives, so don’t rush this step.
- Cook the cauliflower rice. While the veggies cook, heat the cauliflower rice in the microwave for 3 to 4 minutes, or sauté it in a separate pan with a little oil for 5 minutes. Season with a pinch of salt.
- Slice the chicken. Cut the rested chicken into strips against the grain. This keeps it tender instead of chewy.
- Build your bowls. Start with a base of cauliflower rice. Layer on the peppers and onions, then the sliced chicken. Top with avocado, cheese, sour cream, and cilantro. Finish with a lime wedge and hot sauce if you’re feeling brave.
Pro Tips
- Don’t skip the resting step. Cutting into chicken right off the heat lets all the juice run out onto your cutting board instead of staying in the meat. Five minutes makes a real difference.
- Use a hot pan for the veggies. If the pan isn’t hot enough, the peppers steam instead of char, and you lose that smoky flavor that makes fajitas taste like fajitas.
- Thighs stay juicier than breasts. If you’ve had dry chicken breast disappointments before, thighs are much more forgiving and taste just as good in this dish.
- Toast your spices first for extra depth. If you have 60 seconds, warm the chili powder, cumin, and smoked paprika in a dry pan before adding them to the marinade. It wakes the spices up.
- Buy pre-riced cauliflower to save time. Homemade cauliflower rice is great, but the frozen bagged version is genuinely just as good here and saves a chunk of prep time.
Substitutions and Variations
This recipe is forgiving, so play around with it.
| Change | How to do it |
|---|---|
| Protein swap | Shrimp or steak work great instead of chicken. Cook shrimp 2 to 3 minutes per side. |
| Dairy free | Skip the cheese and sour cream, or use dairy free versions. Tahini or cashew crema works too. |
| Extra low carb | Swap cauliflower rice for shredded lettuce or a bed of spinach. |
| Spicier | Add a diced jalapeño to the veggies, or double the chili powder. |
| Make it a wrap | Use a low carb tortilla for a handheld version. |
Make Ahead Tips
The chicken can marinate up to 8 hours ahead, which makes this a great “prep in the morning, cook at dinner” kind of meal.
You can also fully cook the chicken and veggies up to 3 days ahead and store them separately in the fridge. Reheat in a hot skillet for a few minutes to bring back some of that char, then build your bowls fresh with the cold toppings.
Leftovers and Storage
Store the chicken, veggies, and cauliflower rice in separate airtight containers in the fridge for up to 4 days. Keep the avocado, sour cream, and cheese separate and add them fresh when you reheat.
Reheat the chicken and veggies in a skillet over medium heat for a few minutes, or in the microwave in 30 second bursts. The skillet method keeps the veggies from turning mushy.
These bowls also freeze well minus the toppings. Freeze the cooked chicken and veggies flat in a freezer bag for up to 2 months, then thaw overnight in the fridge before reheating.
FAQ
Can I use chicken breast instead of thighs?
Yes. Just watch the cook time closely since breasts dry out faster than thighs. Pull them at 165°F and let them rest just like the thighs.
Is cauliflower rice actually good, or just a diet substitute?
Honestly, it’s good on its own merits once it’s seasoned and has something flavorful sitting on top of it, like this fajita chicken. It’s not trying to trick you into thinking it’s regular rice, it’s just a solid low carb base.
How many carbs are in one bowl?
Roughly 12 to 15 grams of net carbs per bowl, depending on how much cheese, sour cream, and avocado you pile on. The peppers and onions carry most of the carbs here.
Can I make this in advance for meal prep?
Yes, this is one of the better meal prep recipes I make. Portion the chicken, veggies, and cauliflower rice into containers and add the fresh toppings right before eating.
What can I serve alongside this?
A simple side salad or some roasted zucchini rounds this out nicely if you want more volume without more carbs.
Wrapping Up
That’s the whole recipe, and I’m willing to bet it becomes one of your go-to weeknight dinners too.
It’s fast, it’s colorful, and it doesn’t feel like you’re missing anything by skipping the tortilla.
Make a batch, load up your bowl exactly how you like it, and let me know in the comments how it turned out. I’d also love to hear what toppings you added if you switched things up.
