What makes this steak so great is that it’s just as delicious warm for dinner as it is cold and eaten for lunch. When choosing harissa for the marinade, look for it in a tube or can, which will have a thick, paste-like consistency (we want that explosive, concentrated red chile flavor), rather than jarred harissa, which tends to be saucier and has less potent flavor. Yogurt is the actual secret ingredient here, because the sugars will caramelize and help the meat develop a beautiful brown crust. If you have time, let the steak marinate in the yogurt mixture for a few hours or overnight to let it tenderize the meat, but if you only have 15 minutes while the grill heats up (see Tip), it’ll still be delicious.

Ingredient Substitution Guide

Preparation

  1. Step 1

    Make the marinade: Mix the harissa, yogurt, garlic and 1 tablespoon oil in a large bowl.

  2. Step 2

    Using paper towels, pat the steak dry and season generously with salt and pepper. Add the steak to the bowl and, using tongs, toss the steak so that the marinade covers the meat. Let marinate at room temperature while you prepare the onions and heat the grill, or cover and chill for up to 12 hours.

  3. Step 3

    Peel the onions, leaving the root end attached, then slice into 1-inch wedges. Transfer to a large baking sheet and drizzle with 2 tablespoons oil. Season with salt and pepper and toss to combine.

  4. Step 4

    Heat the grill on medium-high for 10 minutes. When hot, transfer the steak directly from the marinade to the grill, then arrange the onions on the grates. Grill until the onions are nicely charred all over, 2 to 3 minutes per side, and the steak has formed a beautiful caramelized crust on both sides, 4 to 6 minutes per side for medium-rare. Transfer onions and steak to the baking sheet as they finish cooking. Let the steak rest for 5 to 10 minutes.

  5. Step 5

    While the steak is resting, combine the tomatoes, vinegar, remaining 3 tablespoons oil and the grilled onions in a medium bowl. Season with salt and pepper and toss together. Warm the bread on the grill.

  6. Step 6

    Slice the steak against the grain and serve with the tomatoes and onions (and their juices) and the warmed flatbread.

Tips
  • If you only have jarred harissa, try marinating the steak overnight to extract as much flavor as possible from the chile paste.
  • This recipe is intended for outdoor grilling, but if you want to give it a go indoors, be sure your kitchen is well ventilated and be ready to crack some windows. The grilling of the marinated steak will generate smoke.

THE STEAK - so good, SO crusty in the best possible way, and toothsome -- and the tomatoes with the onions were glorious. I actually pretended that the dressing was a "red chimichurri" and liberally applied it to the steak on my plate to the same effect. I will note that I marinated the steak for 24hrs for convenience. I am not sure how it would turn out with a shorter marination time.

This was outstanding! Did it all on the grill and then thinly sliced the steak and served it on grill toasted pita's along with the tomato and onion mixture topping it, everyone loved the flavor with the perfect amount heat and flavor delivered by the harissa, black pepper, along with the onion and tomato mixture.

Just made, served, and at the steak and it was great! Happened to have all the ingredients so made it as specified. Steak was delectably tender AND delicious. Really liked the grilled red onion with heirloom tomatoes too. Served with a side of sliced, roasted potatoes. Will make the whole dinner again I in the future—maybe for guests.

Someone else in the comments used mayonnaise, which sounds plausible! @shoshana

Nothing not to like! I marinated overnight with Trader Joe's harissa. It has a kick to it and flavored the steak nicely. Skewered the grilled onions so none were lost. Served with rice pilaf instead of pita. Would very much do this again, and soon!

This was excellent! The only flatbread I had were some fresh corn tortillas so I made “fajitas”. Marinated the meat as written, grilled a bell pepper and threw that in with the onion and tomato mixture. Served with the tortillas, cilantro, lime and a little yogurt. The meat was so good I’ll have to do it again without the toppings! Harissa paste was key for me- the flavor did not get lost. This is now my favorite flank steak.
