Ingredients
Method
- Prep the steak: Pat the steak dry and slice it against the grain into thin strips about 1/2 inch wide. Trimming visible fat keeps it lean and tender.
- Make a quick marinade: In a bowl, combine 1 tablespoon oil, juice of 1 lime, 1 tablespoon soy sauce, 2 minced garlic cloves, 1 teaspoon chili powder, 1 teaspoon ground cumin, 1 teaspoon smoked paprika, 1/2 teaspoon oregano, 1/2 teaspoon black pepper, and 1/2 teaspoon salt. Add a pinch of cayenne if you like heat.
- Marinate: Toss the steak strips in the marinade and let sit for 20–30 minutes at room temperature, or up to 8 hours in the fridge. Short marinade, big payoff.
- Slice the vegetables: Cut bell peppers into thin strips and onion into thin half-moons. Keep them similar in size for even cooking.
- Heat the pan properly: Set a large cast-iron skillet or heavy pan over medium-high heat. When it’s hot, add 1 tablespoon oil and swirl to coat.
- Sear the steak in batches: Add half the steak in a single layer. Don’t crowd the pan. Sear 2–3 minutes per side until nicely browned but still juicy. Transfer to a plate and repeat with the remaining steak.
- Cook the veggies: In the same skillet, add another teaspoon of oil if needed. Add peppers and onion with a pinch of salt. Cook 5–7 minutes, stirring occasionally, until crisp-tender with some char.
- Bring it together: Return steak and any juices to the pan. Squeeze in the juice of 1 lime, add the remaining minced garlic clove, and toss for 30–60 seconds. Turn off the heat and finish with chopped cilantro and lime zest for brightness.
- Warm the tortillas (if using): Heat tortillas in a dry skillet 20–30 seconds per side or microwave wrapped in a damp towel for 30 seconds. Warm tortillas bend without cracking.
- Assemble and serve: Fill tortillas or bowls with steak and vegetables. Top with avocado, Greek yogurt, salsa, and lettuce. For extra protein and fiber, add black beans. Taste and adjust with a pinch of salt or an extra squeeze of lime.

What Makes This Special
Great fajitas are all about contrast—tender steak, crisp-tender peppers, and zesty accents. Here, you’ll get a juicy sear on the beef without drowning it in oil or sugar.
The seasoning mix is straightforward but punchy, and the cooking method keeps every bite fresh and bright. You can serve it bowl-style or in warm tortillas, and it reheats well for weekday lunches. It’s the kind of meal you’ll make once and keep on repeat.

Keeping It Fresh
Cooked steak and veggies keep well for 3–4 days in the fridge. Store them in separate airtight containers to maintain texture. If you’re prepping for lunches, portion steak, veggies, and beans together and keep toppings like salsa and yogurt in small containers on the side.
Reheat gently on the stovetop over medium heat or in the microwave for 60–90 seconds. Avoid overcooking when reheating so the steak stays tender.
Tortillas are best warmed right before serving, and fresh lime juice added at the end makes leftovers taste bright again.
Why This is Good for You
- High protein: Lean steak delivers a strong protein punch that supports muscle repair and helps keep you full longer.
- Fiber and micronutrients: Bell peppers and onions bring vitamin C, antioxidants, and fiber for better gut health and immune support.
- Smarter fats: Using a small amount of olive or avocado oil adds heart-healthy fats without going overboard.
- Balanced plate: Pair with whole wheat tortillas or brown rice for steady energy, and add beans for extra fiber and plant protein.
- Lower sodium, big flavor: Seasonings and citrus let you use less salt while still getting bold, satisfying taste.
What Not to Do
- Don’t over-marinate in acid: More than 8–10 hours in lemon or lime juice can make the steak mushy.
- Don’t crowd the pan: Overcrowding steams the meat. Cook in batches to get that flavorful sear.
- Don’t slice with the grain: Cutting against the grain shortens the muscle fibers and keeps each bite tender.
- Don’t skip resting time: Letting the steak sit while you cook the veggies helps juices redistribute for better texture.
- Don’t drown it in oil: A little goes a long way. Too much oil dulls the flavors and adds unnecessary calories.
Alternatives
- Protein swaps: Try chicken breast or thighs, turkey, shrimp, or extra-firm tofu.
For tofu, press well, marinate, and sear until golden.
- Low-carb base: Serve over cauliflower rice or lettuce instead of tortillas. Add extra peppers and onions for volume.
- Grill option: Grill the steak whole, rest, then slice. Grill peppers and onions in a basket for charred flavor.
- No soy: Use coconut aminos and a pinch more salt.
You still get savory depth with less sodium.
- Spice adjustments: Mild? Skip cayenne. Smoky?
Add more smoked paprika or a dash of chipotle.
- Dairy-free: Swap Greek yogurt for mashed avocado or cashew crema.
- Budget tip: Use top round or sirloin tip and marinate a bit longer. Slice thinly against the grain to keep it tender.
FAQ
What cut of steak works best?
Flank, skirt, or sirloin are top picks. They’re flavorful, lean, and cook quickly.
Just slice against the grain and don’t overcook.
How do I keep the steak tender?
Use a short, flavorful marinade, cook over high heat, and avoid well-done. Medium or medium-rare stays juicier. Thin slices against the grain are key.
Can I make this ahead?
Yes.
Marinate up to 8 hours, then cook. Or cook everything and store for 3–4 days. Keep toppings separate and add fresh lime when serving.
What are the best high-protein add-ins?
Black beans, pinto beans, or a scoop of nonfat Greek yogurt bump protein without much effort.
You can also add egg whites to a breakfast fajita scramble.
Are corn or whole wheat tortillas healthier?
Both can be good choices. Whole wheat tortillas offer more fiber and protein per tortilla, while corn tortillas are naturally gluten-free and usually lower in calories.
How spicy is this recipe?
It’s mild to medium as written. Increase or decrease heat with cayenne, chipotle, or fresh jalapeños to match your taste.
Can I cook this in the oven?
Yes.
Roast peppers and onions at 425°F (220°C) for 15–20 minutes. Broil the marinated steak strips on a sheet pan for 3–5 minutes, watching closely, then toss everything together with lime and cilantro.
What if I don’t have a cast-iron pan?
Any heavy skillet works. Stainless steel sears well; nonstick will do in a pinch, but you may get less browning.
Preheat thoroughly before adding steak.
