storage/reheating

FAQs

What’s the best cut of steak for fajitas?

Flank or skirt steak are ideal—they’re lean, flavorful, and perfect for quick grilling and slicing thin against the grain.

Do I have to marinate the steak?

Yes, even a short marinade enhances flavor and tenderizes the meat. Aim for at least 30 minutes.

Can I cook fajitas indoors?

Absolutely. Use a grill pan or cast iron skillet for the steak and sauté the veggies on the stovetop.

How do I know when the steak is done?

Use a meat thermometer: 130°F for medium-rare, 140°F for medium. Let it rest before slicing.

Should I slice steak before or after grilling?

Grill first, then rest and slice against the grain for maximum tenderness.

Can I freeze the leftovers?

Yes—freeze cooked steak and veggies for up to 2 months. Thaw and reheat before serving.

Are steak fajitas healthy?

Yes! They’re packed with lean protein and vegetables. Use whole-grain or lettuce wraps for an even healthier option.

What toppings go best with steak fajitas?

Avocado, salsa, shredded cheese, sour cream, hot sauce, lime, and cilantro are all great options.

Can I use store-bought fajita seasoning?
