❓ Frequently Asked Questions About Beef Flank Steak Fajitas

1. How long should I marinate the flank steak?

Marinate for at least 30 minutes, but for best flavor and tenderness, let it sit for 2 to 4 hours in the fridge. Do not marinate longer than 8 hours or the acid can start to break down the meat too much.

2. Can I use a different cut of beef?

Yes, skirt steak or sirloin steak work well too. Just adjust cooking time based on thickness and always slice against the grain for tenderness.

3. What if I don’t have a grill?

No problem. Use a cast iron skillet or heavy pan over high heat. It will still give you a nice sear and that sizzling fajita effect.

4. How do I store leftovers?

Store leftover steak and veggies in an airtight container in the fridge for up to 3 days. Reheat in a skillet over medium heat to keep the texture good.

5. Can I make these fajitas gluten free?

Absolutely. Just use corn tortillas instead of flour and check that your marinade ingredients are gluten free. Most are, but always double check labels.
