How to Make Juicy Steak Fajitas
1. Make the Marinade
In a large bowl or zip-top bag, whisk together soy sauce, lime juice, oil, chili powder, cumin, garlic, black pepper, and sugar (if using).
2. Marinate the Steak
Add steak to the marinade, ensuring it’s fully coated. Seal and refrigerate for at least 3 hours, up to 10 hours for maximum flavor.
3. Prep the Vegetables
Toss sliced peppers and onions with olive oil, salt, and pepper. Set aside.
4. Cook the Vegetables
Heat a cast-iron skillet or grill pan over medium-high heat. Cook vegetables for 5–8 minutes, stirring occasionally, until tender-crisp and lightly charred. Remove and set aside.
5. Cook the Steak
Remove steak from marinade and pat dry. Sear in the hot skillet for 3–5 minutes per side, depending on thickness and desired doneness.
6. Rest & Slice
Let steak rest for 5 minutes, then slice thinly against the grain.
7. Combine & Serve
Return steak and vegetables to the skillet, toss briefly to heat through, and serve immediately with tortillas and toppings.
Storage & Meal Prep
- Refrigerator: Store cooked steak and vegetables for up to 4 days
- Reheat: Skillet or microwave until warmed
- Meal Prep Tip: Store tortillas separately for best texture
