Ingredients

• For the steak and marinade:
  • 1.5–2 pounds flank steak or sirloin, trimmed
  • 3 tablespoons olive oil
  • 3 tablespoons fresh lime juice (about 2 limes)
  • 2 teaspoons lime zest
  • 3 cloves garlic, minced
  • 2 teaspoons chili powder
  • 1 teaspoon ground cumin
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon dried oregano
  • 1 teaspoon kosher salt
  • 1/2 teaspoon black pepper
  • 1 teaspoon honey or maple syrup (optional, for browning)
• For the fajita veggies:
  • 3 bell peppers (mix of red, yellow, green), thinly sliced
  • 1 large red onion, thinly sliced
  • 1 tablespoon olive oil
  • 1/2 teaspoon kosher salt
  • 1/2 teaspoon ground cumin
  • 1/2 teaspoon smoked paprika
• For serving and meal prep:
  • 3–4 cups cooked rice or cauliflower rice
  • 1/4 cup chopped fresh cilantro
  • Lime wedges
  • Optional toppings: sliced avocado, pico de gallo, salsa verde, Greek yogurt or sour cream, shredded cheese, jalapeños

How to Make It – Instructions

1. Mix the marinade: In a bowl, whisk olive oil, lime juice/zest, garlic, chili powder, cumin, smoked paprika, oregano, salt, pepper, and honey.

   It should smell like a taco truck parked in your kitchen.

2. Marinate the steak: Place steak in a zip-top bag or shallow dish. Pour marinade over, coat well, and refrigerate at least 30 minutes, up to 8 hours. Pro tip: Longer = more flavor, but don’t exceed 12 hours or the acid can “cook” the edges.
3. Prep the veggies: Toss sliced peppers and onions with olive oil, salt, cumin, and smoked paprika. Keep them evenly coated for that signature fajita sizzle.
4. Cook the veggies: Heat a large skillet over medium-high until hot.

   Add veggies and cook 6–8 minutes, stirring occasionally, until soft with charred edges. Remove to a plate.

5. Sear the steak: Pat the steak dry (crucial for browning). Add a little oil to the hot skillet.

   Sear 3–5 minutes per side for medium-rare, depending on thickness. Aim for 130–135°F internal temp. Rest 5–10 minutes.

6. Slice the steak: Slice against the grain into thin strips.

   This is the difference between “wow” and “why is this chewy?”

7. Build the bases: Divide cooked rice or cauliflower rice among 4–5 meal prep containers. Add a squeeze of lime and sprinkle of cilantro for freshness.
8. Add veggies and steak: Portion fajita veggies and steak on top of the base. Keep any cold toppings (avocado, yogurt, salsa) separate until serving.
9. Finish strong: Add extra lime wedges to each container.

   A quick squeeze before eating wakes everything up, IMO.

Storage Tips

• Fridge: Store bowls in airtight containers for up to 4 days. Keep wet toppings separate to avoid sogginess.
• Freezer: Freeze rice/cauli rice and veggies with steak for up to 2 months. Thaw overnight, then reheat.

  Add fresh toppings after warming.

• Reheat: Microwave 60–90 seconds, stir, then another 30–60 seconds until hot. Or rewarm in a skillet with a splash of water or broth to keep it juicy.
• Avocado strategy: Add day-of or store with a spritz of lime and plastic wrap pressed directly on the surface to slow browning.

Nutritional Perks

• High-quality protein: Steak delivers all essential amino acids for muscle repair and steady energy.
• Fiber and antioxidants: Bell peppers and onions bring vitamin C, quercetin, and fiber to support immunity and gut health.
• Smart carbs your way: Choose brown rice for long-lasting fuel, white rice for quick energy, or cauliflower rice for a low-carb route.
• Healthy fats: Olive oil and optional avocado support nutrient absorption and satiety—aka fewer 3 p.m. snack attacks.

Common Mistakes to Avoid

• Over-marinating: More than 12 hours can make the surface mushy. Set a timer and don’t let it go rogue.
• Skipping the pat-dry step: Wet steak steams instead of sears.

  Paper towels are your friend.

• Crowding the pan: Overloading reduces heat and kills the char. Work in batches if needed.
• Slicing with the grain: Against the grain = tender. With the grain = gym chew toy.
• Adding cold toppings too early: Salsa, yogurt, and avocado belong on top right before eating to keep textures on point.

Different Ways to Make This

• Sheet pan method: Broil steak and seasoned veggies on a foil-lined sheet at the top rack.

  Veggies go first (8–10 minutes), then push aside and broil steak 3–5 minutes per side.

• Grill option: Preheat grill to high. Sear steak 3–4 minutes per side; grill peppers/onions in a basket until lightly charred.
• Spice twist: Add chipotle powder for smoky heat or a splash of soy sauce for umami depth (FYI, not traditional but very tasty).
• Low-carb swap: Use cauliflower rice and add extra peppers/onions. Finish with avocado for staying power.
• Protein variations: Try chicken thighs, shrimp (marinate 15–20 minutes only), or portobellos for a plant-forward option.
• Sauce it up: Quick crema = Greek yogurt, lime juice, and a pinch of salt.

  Drizzle right before eating.

FAQ

What cut of steak works best for fajitas?

Flank steak is classic for its deep flavor and thin grain, but sirloin is a great, slightly more tender alternative. Skirt steak is also fantastic if you can find it. Whatever you choose, slice against the grain after resting.

How long should I marinate the steak?

Aim for 30 minutes to 8 hours.

That window gives you bold flavor without compromising texture. If timing gets weird, you can dry-brine with salt for 30 minutes, then add the rest of the marinade for another 30.

Can I make this spicy?

Absolutely. Add 1/2–1 teaspoon cayenne or chipotle powder to the marinade, or top with sliced jalapeños.

You can also finish with hot sauce for a customizable kick.

How do I keep the veggies from getting soggy?

High heat, don’t crowd the pan, and stop cooking when they’re tender-crisp with charred edges. If meal-prepping, store them separately or on top of the rice, not under it.

What’s the best way to reheat without drying out the steak?

Use short bursts in the microwave with a cover, or toss in a hot skillet with a tablespoon of water or broth. Warm just until heated through; overheating is the fast track to sadness.

Can I make it dairy-free and gluten-free?

Yes.

The base recipe is naturally gluten-free and dairy-free. Just avoid flour tortillas or dairy toppings, and check your spices are certified GF if you’re sensitive.
