Ingredients for Low Carb Steak Fajita
To make these fantastic Low Carb Beef Fajita dishes, you’ll need just a few simple ingredients. The star is, of course, the steak, which should be thinly sliced against the grain for the best texture. We’ll also use colorful vegetables like bell peppers and onions, sliced for that classic fajita look. Olive oil forms the base for cooking, while lime juice adds a bright, zesty flavor. For that signature fajita taste, we’re using a blend of chili powder, cumin, garlic powder, and onion powder. A pinch of cayenne pepper adds a little heat if you like! Salt and black pepper are essential for seasoning. These components come together to create a truly delicious and satisfying meal.
- 1.5 lbs flank steak, thinly sliced – choose flank or skirt steak for the best results
- 1 large bell pepper (any color), sliced – for vibrant color and sweet crunch
- 1 large onion, sliced – adds a savory depth
- 2 tablespoons olive oil – divided for marinating and cooking
- 1 tablespoon lime juice – adds a fresh, zesty kick
- 1 teaspoon chili powder – for a mild warmth
- 1 teaspoon cumin – earthy and aromatic
- 1/2 teaspoon garlic powder – essential for savory flavor
- 1/2 teaspoon onion powder – intensifies the onion taste
- 1/4 teaspoon cayenne pepper (optional) – for a touch of heat

How to Make Low Carb Steak Fajitas
Whipping up these amazing Low Carb Steak Fajitas is surprisingly simple, and the results are incredibly rewarding. The aroma alone will have everyone gathering in the kitchen!
- Step 1: First, let’s marinate that beautiful steak. In a medium bowl, combine the thinly sliced steak with 1 tablespoon of olive oil, the fresh lime juice, chili powder, cumin, garlic powder, onion powder, and the cayenne pepper if you’re feeling a little adventurous. Don’t forget a good pinch of salt and black pepper! Toss everything together gently with your hands until the steak is evenly coated. Let it sit and soak up all those delicious flavors for at least 15 minutes while you prep your veggies.
- Step 2: Now, let’s get cooking! Heat the remaining 1 tablespoon of olive oil in a large skillet or a cast-iron pan over medium-high heat. You want that pan nice and hot so everything sears beautifully.
- Step 3: Carefully add the marinated steak to the hot skillet. Try to lay it in a single layer so it browns nicely instead of steaming. Cook for about 2-3 minutes per side, just until it’s nicely browned and cooked to your preferred doneness. You’ll see those little crispy edges forming – that’s flavor! Remove the steak from the skillet and set it aside on a plate.
- Step 4: Toss the sliced bell pepper and onion into the same skillet. They’ll pick up all those tasty bits left from the steak. Cook, stirring occasionally, for about 5-7 minutes. You want them to get tender-crisp, with just a slight bite left.
- Step 5: Now, bring it all back together! Return the cooked steak to the skillet with the softened vegetables. Give everything a good stir to combine and let it heat through for another minute. This is where the magic happens, creating the perfect flavor profile for your Steak Fajitas No Tortilla creation.
- Step 6: Serve your delicious Steak Fajitas No Tortilla immediately. The sizzle and smell are incredible!
Pro Tips for the Best Low Carb Steak Fajita
Want to elevate your fajita game? I’ve picked up a few tricks over the years that make all the difference for these Keto Steak Fajitas.
- Thinly slice your steak against the grain. This is crucial for tenderness!
- Don’t overcrowd the pan when cooking the steak or veggies. Cook in batches if necessary to ensure a good sear.

Can I make Low Carb Steak Fajitas ahead of time?
Yes, you can definitely prep components ahead! Marinate the steak up to 24 hours in advance and chop your veggies. Store them separately in the fridge. When you’re ready to cook, it’s just a matter of sautéing. This is a great way to save time, similar to how you might prep ingredients for sloppy joe bowls.
How do I avoid common mistakes with Low Carb Steak Fajitas?
A common mistake is overcooking the steak, which makes it tough. Another is not slicing the steak thinly enough against the grain. Also, resist the urge to stir the steak constantly; let it sear! Proper cooking temperatures are key, much like when making focaccia bread.
Best Ways to Serve Low Carb Steak Fajitas

Simply spoon the steak and veggie mixture over a bed of fluffy cauliflower rice, then top with your favorite low-carb goodies like diced avocado, a dollop of sour cream, and a sprinkle of shredded cheese. It’s a complete, satisfying meal that feels like a treat.
Another fantastic option is to enjoy them straight from the skillet with a side of fresh pico de gallo and a creamy guacamole. The bright, fresh flavors perfectly complement the rich, savory steak. You could also serve them alongside some simple grilled zucchini or a crisp green salad for a lighter, yet still incredibly flavorful, meal.
