Grilled Fajitas

A special marinade gives the steak in these fajitas outstanding flavor that's always a hit with my family. It's a fun and satisfying summer main dish using garden-fresh peppers and onions. —Cheryl Smith, The Dalles, Oregon

    4 servings


  • 1 beef flank steak (about 1 pound)
  • 1 envelope onion soup mix
  • 1/4 cup canola oil
  • 1/4 cup lime juice
  • 1/4 cup water
  • 2 garlic cloves, minced

  • In a large shallow dish, combine the first nine ingredients; add steak. Turn to coat; cover and refrigerate 4 hours or overnight.
  • Drain and discard marinade. Grill over high heat until meat reaches desired doneness (for medium-rare, a thermometer should read 135°; medium, 140°; medium-well, 145°).

    These are so good! Will definitely make again. I followed the recipe exactly, and I used the leftover marinade to cook in with the onions and peppers as a sauce. My brother-in-law couldn't stop raving about the marinade. I served them with the lime wedges and sour cream too.

    I made this recipe this past weekend and was blown away!!! We always used a fajita package before, but never again. I did add some fresh cilantro to the marinade. Will be making this again for sure! Thanks for posting.

    What a special dinner we had last night and the best part was when my husband, who's eaten my cooking for 55 yrs., told me what a delicious dinner it was yet he grilled the steak. For a side, I made Spanish Rice with a short-cut. While prepping the pepper/onions for the Fajitas, I chopped and sauteed extras, then added to cooked rice, along with a jar of homemade salsa with black beans. I'm anxious to try this dish now with chicken.-Carol Kinelski, Richmond, Kentucky
