  • Turn over several times to mix well. Refrigerate 20- 24 hours. The long marinade time really infuses the steak and vegetables with delicious flavors. I’ve tried marinating for less time and was disappointed in the flavor.

  • Make a foil packet around flour tortillas and set aside.
  • Prepare a grill fire to about 350° with pecan or hickory for smoke flavor.

  • Remove steak and vegetables from marinade onto the grill over indirect fire – use a grill pan or griddle if you have large grates. Spread evenly and close the lid. Discard marinade.
  • Cook in 5 minute intervals, turning the mixture with a spatula or tongs to cook evenly.

  • Continue to cook for 15- 20 minutes or until steak reaches about 135° to 140° with a digital  meat thermometer.
  • During the last 5 minutes, warm the tortillas.

  • Serve with sour cream, salsa and guacamole if desired.

How to Store and Reheat:

  • Store leftovers in an airtight container in refrigerator up to 4 days.
  • Reheat in a skillet coated with olive oil over medium heat. Stir continually until heated through, about 5 minutes.

Best Steak for Fajitas:

Our favorite is sirloin steak because it’s always tender and has great flavor. Flank steak or hanger steak are commonly used and will work just fine with this recipe. Use what you have have on hand or can find on sale.

Traditionally fajitas are made in a sizzling hot cast iron skillet but when they are grilled with hardwood smoke you get that smoky delicious flavor that just makes it even tastier.

If you are craving a sizzling plate of steak fajitas, try making them on the grill. It is a really simple and delicious dinner perfect for busy weeknights, plus you can count on the whole family enjoying them!
